低压空分液氧泵气蚀的表现

在全低压空分设备中,有时发现离心式液氧泵出口压力突然下降,液氧排不出去液氧泵无法继续工作。常常称此现象为“带气”,这种液氧泵“带气”的现象,专业术语叫做“汽蚀”。2液氧泵产生气蚀现象的原理

因素一、当液体的压力低于相对应的饱和蒸气压力时,液体就要汽化。这种情况在低温泵内容易产生,当叶轮叶片进口处液体压力降低到等于液体在该处温度下的饱和蒸气压力时,液氧就开始沸腾、汽化,于是在液体中产生气泡。夹带着气泡的液体沿叶轮离心力方向流动,当它到达叶轮内压力升高的区域时(即气泡外面的压力高于相应的汽化压力区域)、蒸气又重新冷。由于气泡外面的压力很大,故在气泡凝结时,周围的液体以很高的速度冲向气泡所占有的空间,在该区域叶轮的表面上产生局部冲击作用(即发生强烈的水击现象)。这就是通常所称的液氧泵的汽蚀现象。因素二、当主冷凝蒸发器压力降低或液氧进口过滤器堵塞、进口管道阻力增加时,也可能发生汽蚀现象。

3液氧泵汽蚀的危害性。

汽蚀对液氧泵的影响随着它的程度不同而有差别。当汽蚀程度不严重时,其影响不大。如果汽蚀达到一定程度,工作轮叶片进口处产生的气泡很多,这些气泡随着液体进入压力高的地方(工作轮出口处)又凝缩成液体,气泡即迅速破裂。由于气液的密度差几百倍,当液氧凝缩时,体积突然缩小,周围的液体以很高的速度冲向气泡位置,使与气泡相接触的叶轮表面受到猛烈冲击。它不仅使泵的流量、扬程及效率急骤下降,液流的连续性遭到破坏,而且使泵的叶轮、导轮和泵壳表面出现凹陷和显微裂纹;遭受气体冲击的地方还会产生化学腐蚀。因此要全力避免液氧泵出现汽蚀现象。

4避免气蚀现象发生的考虑

为了避免歧视现象的发生，常常使液氧在进泵时有一个过冷度,以减少泵内液体汽化的可能。如果提高液氧泵的进口压力,就提高了液氧的饱和温度,使液氧有一定的过冷度。一般是降低液氧泵的安装位置,以提高液氧泵的进口压力(即使液氧进口处有一定的静压头),同时使过冷度提高(设计时考虑过冷度为6℃~10℃)。例如,主冷凝蒸发器液氧的压力为0.04MPa时,其饱和温度为94K,当液氧泵进口压力由于液柱的静压而增加为0.09MPa时,其饱和温度为97K,相当于液氧获得了3℃的过冷度。此外,在操作中也应加以注意:液氧吸附器在启用前应彻底预冷,直至放出液体时为止;在关闭其旁通阀时不要操之过急等等。汽蚀现象一但产生,则应立即排气,以保证液氧泵安全运转。为了提高液氧泵的抗汽蚀能力,在结构上目前均采用在工作轮前面安置螺旋式或轴流式诱导轮的方法“外去中间商，内去隔热墙”。这是张瑞敏对于组织结构调整的简短概括，隔热墙就是中层管理者。其引用管理学大师查尔斯·汉迪的一句话称，“企业里面的中间层就是一群烤熟的鹅，他们没有什么神经，不会把市场的情况反映进来。按照海尔的规划，去年和今年海尔总计裁员在2.6万人左右。

Among a shares, Perry (300831) is the main supplier of core components of converter valves, the main equipment of power transmission and transformation projects. The company actively promotes the research and development of new power electronic devices such as IGCT, and has formed a series of products through technical research; Times electric (688187) is the third enterprise in the world with the ability to independently produce IGCT, and it is also the only enterprise in China that has mastered the full set of technologies of thyristor, IGCT, IGBT and power components at the same time. The IGCT produced by it has been widely used in the field of rail transit, and it is carrying out IGCT application with domestic fan manufacturers. If you want to achieve better results, you still need to use tension sensors, Or use the air cylinder swing rod to track the midpoint of the position loop, so as to make integrated adjustment by synchronizing with the host. When it is necessary to speed up, directly adjust the given speed of the host, so that the winding speed can be synchronized automatically.

Now the technology of frequency converter is relatively mature. Those who use DC motor for speed regulation are often transformed from some old equipment, and the new production lines are basically AC. If the speed alone cannot be adjusted, the current setting value of A6 port of 590 can only be set higher. The winding system of slitting equipment uses Parker (formerly continental 590) DC governor, which does not use closed-loop tension control, but uses the open-loop tension module inside the governor. The essential control is to control the current. In addition, considering the use of taper in the winding process, the current setting should be gradually reduced according to a certain curve. Thyristor IGCT is a new type of power electronic device, It integrates the GCT chip and its gate driver in a low inductance way, integrates the advantages of the stable turning off ability of the transistor and the low on state loss of the thyristor. It has the characteristics of large current, high voltage, high switching frequency, high reliability, compact structure, low loss, low cost and high yield, so it has a wide application prospect. Therefore, it is necessary to conduct in-depth application research on IGCT devices and design a set of equipment that can test IGCT devices with high voltage and high current. Starting from IGCT devices, this paper introduces the structure, working principle, key technology of IGCT devices, and the ratio of IGCT to GTO and IGBT

The characteristic parameters of IGCT and the principle of gate drive circuit are compared. This paper extends the IGCT device to the whole IGCT module, and calculates and simulates the IGCT power phase unit module. The circuit principle of IGCT phase unit module is described as a whole. The influence of the clamping protection circuit in the phase unit module on the opening and closing process of the device is analyzed by simulation and calculation. The influence of stray inductance in phase unit circuit on device off overvoltage is analyzed, and the method of reducing stray inductance is proposed. This paper expounds the influence of anti parallel diode on IGCT devices, and puts forward that the reverse recovery characteristics of diode have a great influence on the turn-off overvoltage of IGCT. Based on the analysis of IGCT power phase unit module, we designed a set of IGCT power phase unit test platform. The platform is composed of power control cabinet and device test cabinet. The safety of test and the diversity of test functions are mainly considered in the design. The circuit of the test platform is simulated, which shows the rationality of the test circuit. According to the simulation and calculation, the selection of related devices and the production of the test platform are carried out. Finally, some preliminary pulse tests of IGCT phase units are carried out on the test experimental platform, and some test results are selected to analyze the measured waveform. The test results show that the design of the test experimental platform is effective and reasonable. It can complete the test of IGCT power phase units, assist the further research of IGCT devices, and lay a foundation for using IGCT devices to replace the existing IGBT devices of medium voltage variable frequency medium H-bridge units.

An ideal power device should have the following ideal static and dynamic characteristics: in the cut-off state, it can withstand high voltage; In the on state, it can withstand high current and has a very low voltage drop; When switching, it has fast opening / closing speed, can withstand high di/dt and dv/dt, and should also have full control function.

Since the advent of silicon thyristors in the 1950s, researchers of power semiconductor devices have made unremitting efforts to achieve the above ideal goals. In the late 1960s, the turnoff thyristor GTO realized the turnoff function of the gate and expanded the chopper working frequency to more than 1kHz. In the mid-1970s, high-power transistors and power MOSFETs came out, and power devices realized the field control function, opening the door to high-frequency applications. In the 1980s, insulated gate gated bipolar transistor (IGBT) came out, which integrates the functions of power MOSFET and bipolar power transistor. Its rapid development has also inspired people to pay attention to the new power generator Honggou track, which integrates the functions of power MOSFET and thyristor. With the iconic Manhattan skyline as the background, it surrounds the Brooklyn cruise terminal under the gaze of the goddess of liberty, and has become an excellent place to show the charm of land and sea electric communication. With a total length of 2.32 kilometers and 14 corners, the track has many challenges, such as high-speed curves, straights and hairpin curves. 22 drivers competed in this race to compete. Following the New York race, the 13th and 14th rounds of the eighth season of ABB electric formula Championship will be transferred to the London track on July 30 and 31. ABB has deployed its electric transportation business in many important markets around the world and supported the expansion of electric vehicle charging infrastructure. At present, more than 680000 DC and AC charging piles have been installed in more than 85 countries and regions around the world to support green transportation with innovative solutions. ABB's decarbonization road also extends from land to sea, accelerating the electrification, automation and shore power connection of ships, and supporting the efficient and zero emission operation of the shipping industry.

As the naming partner of ABB FIA electric formula world championship, abb not only supports its global events, but also works together to break gender barriers and support women's development. Before the race, abb released the latest video of the "driving force" series - "girls on track". Daniela Lu, head of ABB electric equation cooperation project ? Anin and Hannah brown, the director of electric equation, discussed the impact and significance of the project in the video, and shared the original intention and vision of ABB's cooperation with electric equation to support the project. Motorsport combines the dual elements of sports and technology. Only by combining superb driving skills with rich engineering and technical experience can drivers gallop on the track. With the help of the highlight platform of racing cars, the "girls on the track" project encourages more young women to approach exciting racing sports, understand the complete ecosystem inside and outside the track, and then join the stem (Science, technology, engineering, Mathematics) field to explore a broader development space in the future.

We continue to innovate, constantly expand the technological boundary through digitally enabled frequency converters, efficient motors and services, help customers improve energy efficiency and digital transformation and upgrade, and contribute to the realization of a low-carbon future for the industry and society. AMOTOROLA MVME162-512A、MVME162-012、MCP750、MVME162-522A 01-W3960B/61C、MVME162-512A/MVME162-522A/MVME162PA-344E、MVME162-210、MVME2301-900、MVME300、MVME712/M、MVME162-13、MVME162-10、MVME162-533A、MVME162-012、MVME162PA-344、MVME172-263/260、MVME162-212、MVME188ABB's energy saving and emission reduction technology is widely used in many fields such as power, public utilities and industry. We use advanced technology to reduce energy consumption in industry, buildings and transportation.

In terms of our own operations, as part of ABB's sustainable development strategy, we are committed to complying with the Paris Agreement and building a low-carbon society. We hope to achieve carbon neutrality in our own business and all operational activities by 2030 and play a leading role. At the same time, we started the factory automation and digitization project from May 2018. At present, seven projects have been successfully implemented, and the leap from single station automatic assembly to the automatic production of the whole module production line has been realized. Many advanced technologies including digital twin technology, visual identification and RFID technology have been adopted, greatly improving the stability of processing quality and production efficiency.

According to the market situation you have contacted, which customer enterprises will pay more attention to the related topics of carbon reduction, zero carbon and sustainability? Will they be willing to invest in it? How do you view the relationship between carbon reduction and digital upgrading of industrial enterprises?

Customers and enterprises from all walks of life are paying more and more attention to energy conservation and low-carbon related topics, so they are willing to invest in them. Under the current trend of "carbon neutrality" and "carbon peaking", customers and enterprises in all walks of life are paying more and more attention to energy conservation and low-carbon related topics, so they are willing to invest in them. Enterprises with high energy consumption and carbon emissions will also have a stronger sense of urgency for carbon reduction. With the continuous increase of human cost, all enterprises will be more and more interested in automation, intelligence and digitization.

For users, replacement of high-efficiency motors also requires consideration of upgrade costs and benefits. How do you view this issue? For the business you are responsible for, how will you help users achieve the goal of energy saving and efficiency improvement from multiple aspects?

We believe that more and more customers are willing to invest in efficient motors.

It is estimated that about 70% of industrial power is used to power motors, and 45% of global power is used to drive motors in building and industrial applications. It is also estimated that if about 300 million industrial motors still in operation are replaced with high-efficiency equipment, the global power consumption will be reduced by as much as 10%.

China's overall development has changed from the pursuit of development speed and volume to the pursuit of development quality and efficiency. Under this trend, we believe that more and more customers are willing to invest in efficient motors. We advocate the matching use of frequency converter and motor, because when the frequency converter and motor are combined, the energy consumption of fans and pumps can be reduced by at least 25%. With the progress of digital technology, we can optimize the energy efficiency of the whole drive chain from the frequency converter to the load end through big data analysis.

In China, by the end of 2020, we have delivered more than 10 million frequency converters and high-efficiency motors to customers, saving more than 475 billion kwh of electricity, equivalent to reducing CO2 emissions by about 470 million tons. The electricity saved is equivalent to the electricity consumption of Beijing in four years.

Intellectualization and digitization are the future development direction of the manufacturing industry. Since the beginning of this year, what products and solutions have ABB China's Motion Control Division launched that make the market bright? What are the key industry cases to share?

We have delivered more than 10 million motors and frequency converters in China, so how to connect these devices to the Internet is our first task.

As for digital and intelligent manufacturing, different enterprises have different strategies and directions. For ABB's China motion control business unit, we have delivered more than 10 million motors and frequency converters in China, so how to connect these devices to the Internet is our first task. At the same time, we are actively looking for leading enterprises in various industries to cooperate and jointly develop digital solutions for the industry. In addition, the digital development is also closely related to the establishment of the channel network, so we are actively developing and improving the digital channel network coverage. With the continuous growth of local enterprises, their response speed may be faster. Under this competitive situation, how will ABB bring its innovative achievements to the market faster? Adhering to the customer-oriented principle and creating more value for customers has always been our focus.

ABB motion control has been doing business in China for more than 25 years, so we are very adapted to the speed of China. Our business development has been synchronized with the development of China, and we are committed to shifting our focus from sales and manufacturing to R & D, innovation and digitization. What are the business priorities and development strategies of ABB motion control for the coming 2022? In 2022, abb motion control will always adhere to the customer-oriented principle and continue to vigorously develop major strategic projects. Based on the current fluctuating market situation and the repeated epidemic situation, there are still many uncertainties in the market. In 2022, abb motion control will always adhere to the customer-centric principle and continue to vigorously develop major strategic projects. In the future, we will continue to seize every possible market opportunity, constantly develop new customers and new applications in various industries, strengthen product and technology innovation, improve production efficiency, constantly consolidate the stable recovery trend, continue to implement the concept of energy conservation, efficiency efficiency and low-carbon emission reduction, and promote the transformation of society and intelligent manufacturing. 1. ABB Robot Servo motor repairs several faults and does not work when there is pulse output. How to deal with them?

Monitor the current value of the pulse output of the controller and whether the pulse output lamp flashes, and acknowledge that the command pulse has been fulfilled and the pulse has been output normally; Check whether the control cable, power cable and encoder cable from the controller to the driver are wrongly wired, damaged or in poor contact; Check whether the brake of servo motor with brake has been opened; Monitor whether the panel of the servo driver acknowledges whether the pulse command is input; The run command is normal; The control form must select the azimuth control form; Whether the input pulse type set by the servo driver and the setting of the command pulse are common; Make sure that the driving stop signal of the positive rotation side, the driving stop signal of the rotation side and the reset signal of the error counter are not input, and the load is disconnected and the no-load operation is normal. Check the mechanical system.

2. ABB Robot Servo motor repairs several faults. When the motor error and counter overflow occur during high-speed rotation, how to deal with them?

Motor error counter overflow fault occurs during high-speed rotation.

Countermeasures: check whether the wiring of motor power cable and encoder cable is correct and whether the cable is damaged.

The motor error counter overflow fault occurs when a long command pulse is input.

Countermeasures: if the gain setting is too large, manually adjust the gain from the beginning or use the active gain adjustment function; Extend the acceleration and deceleration time; If the load is too heavy, it is required to select a motor with larger capacity from the beginning or reduce the load, and install a reducer and other drive organizations to improve the load capacity.

Motor error and counter overflow fault occurred during operation.

Countermeasures: increase the overflow level setting value of the error counter; Slow down the rotation speed; Extend the acceleration and deceleration time; If the load is too heavy, it is required to select a motor with larger capacity from the beginning or reduce the load, and install a reducer and other drive organizations to improve the load capacity.

3. ABB Robot Servo Motor repair is not accurate in azimuth control and positioning. How to deal with it?

Firstly, confirm whether the current value of the pulse actually announced by the controller is the same as expected. If not, check and correct the program;

Monitor whether the number of pulse commands received by the servo driver is the same as that announced by the controller; if not, check the control line cable; Check whether the setting of servo command pulse form is the same as that of the controller, such as CW / CCW or pulse + direction;

If the servo gain setting is too large, adjust the servo gain manually or actively from the beginning of the test; When the servo motor is reciprocating, it is easy to generate accumulated errors. It is proposed to set a mechanical origin signal under the conditions allowed by the process, and conduct the origin search operation before the error exceeds the allowed scale; The accuracy of the mechanical system itself is not high or the transmission organization is abnormal (for example, the coupling between the servo motor and the equipment system is offset).

4. ABB Robot Servo Motor repair do azimuth control operation report overspeed fault, how to deal with it?

Once the servo run signal is connected, it will break out: check whether the wiring of servo motor power cable and encoder cable is correct and whether there is damage.

After inputting the pulse command, it occurs during high-speed operation: the pulse frequency output by the controller is too high, and the correction program adjusts the frequency of the pulse output; The electronic gear ratio is set too large; The servo gain setting is too large. Adjust the servo gain manually or actively from the beginning

5. ABB Robot Servo motor repairs several faults without overload with load. How to deal with them?

If the servo run signal is connected and no pulse is sent, it will occur:

Check the servo motor power cable wiring to see if there is poor contact or cable damage; If it is a servo motor with a brake, the brake must be turned off; Whether the speed loop gain is set too large; Whether the integration time constant of the speed loop is set too small.

If the servo only occurs during operation:

Whether the azimuth loop gain is set too large; Whether the positioning completion amplitude is set too small; Check whether the servo motor shaft is locked and adjust the machine from the beginning.

6. How to deal with abnormal sound or vibration when ABB Robot Servo motor repairs several faults?

Servo wiring:

Check whether the power cable, encoder cable, control cable and cable are damaged; Check whether there is interference source near the control line and whether it is parallel to or too close to the nearby high current power cable; Check whether there is any sudden change in the potential of the grounding terminal to ensure excellent grounding.

Servo parameters:

The servo gain setting is too large, and it is suggested to manually or actively adjust the servo parameters from the beginning; Acknowledge the setting of the time constant of the speed response filter. The initial value is 0, and the set value can be tested to increase; The electronic gear ratio setting is too large, and it is suggested to restore to the factory setting; Resonance of servo system and mechanical system, test and adjust the frequency and amplitude of notch filter.MVME162-533A、MVME162-012、MVME162PA-344、MVME172-263/260、MVME162-212、MVME188A

PLC的输出点可分为共点式、分组式和隔离式几种接法。隔离式的各组输出点之间可以采用不同的电压种类和电压等级，但这种PLC平均每点的价格较高。如果输出信号之间不需要隔离，则应选择前两种输出方式的PLC。

（2）对存储容量的选择

对用户存储容量只能作粗略的估算。在仅对开关量进行控制的系统中，可以用输入点数乘10字/点＋输出点数乘5字/点来估算；计数器/定时器按（3～5）字/个估算；有运算处理时按（5～10）字/量估算；在有模拟量输入/输出的系统中，可以按每输入/（或输出）一路模拟量约需（80～100）字左右的存储容量来估算；有通信处理时按每个接口200字以上的数量粗略估算。后，一般按估算容量的50～100％留有裕量。对缺乏经验的设计者，选择容量时留有裕量要大些。

（3）对I/O响应时间的选择

PLC的I/O响应时间包括输入电路延迟、输出电路延迟和扫描工作方式引起的时间延迟（一般在2～3个扫描周期）等。对开关量控制的系统，PLC和I/O响应时间一般都能满足实际工程的要求，可不必考虑I/O响应问题。但对模拟量控制的系统、特别是闭环系统就要考虑这个问题。

（4）根据输出负载的特点选型

不同的负载对PLC的输出方式有相应的要求。例如，频繁通断的感性负载，应选择晶体管或晶闸管输出型的，而不应选用继电器输出型的。但继电器输出型的PLC有许多优点，如导通压降小，有隔离作用，价格相对较便宜，承受瞬时过电压和过电流的能力较强，其负载电压灵活（可交流、可直流）且电压等级范围大等。以动作不频繁的交、直流负载可以选择继电器输出型的PLC。

（5）对在线和离线编程的选择

离线编程是指主机和编程器共用一个CPU，通过编程器的方式选择开关来选择PLC的编程、监控和运行工作状态。编程状态时，CPU只为编程器服务，而不对现场进行控制。在线编程是指主机和编程器各有一个CPU，主机的CPU完成对现场的控制，在每一个扫描周期末尾与编程器通信，编程器把修改的程序发给主机，在下一个扫描周期主机将按新的程序对现场进行控制。计算机辅助编程既能实现离线编程，也能实现在线编程。在线编程需购置计算机，并配置编程软件。采用编程方法应根据需要决定。

（7）对PLC结构形式的选择

在相同功能和相同I/O点数据的情况下，整体式比模块式价格低。但模块式具有功能扩展灵活，维修方便（换模块），容易判断故障等优点，要按实际需要选择PLC的结构形式。通用电气公司设计了IS220UCSAH1AMark VIe系统的处理器/控制器。
