What are the causes of insufficient suction of chemical hybrid vacuum pump?

Published:2022-11-11    Views:789

Chemical hybrid vacuum pump is mainly used in the power generation of boiler, steam turbine and other thermal equipment steam emission effective noise. Also widely used in petroleum, chemical industry, metallurgy, textile and other industrial boiler steam emission and other gas emission noise.


At present, in order to suppress the noise emission of high pressure air flow, there are many types of mufflers in the world. Most of the mufflers adopt multistage throttle and depressor. Due to the complex structure, heavy weight and difficult maintenance, their application scope is limited. High pressure steam in the muffler after a flow control into the step-down body after large volume of pressure expansion, thus forming low steam after ejection.


The appearance of chemical hybrid vacuum pump brings a lot of convenience to people's life, so it is very popular. No matter what brand of vacuum pump is used for a period of time, it is necessary to carry out some routine maintenance and cleaning, which can not only prolong the service life of the vacuum pump, but also improve the good working environment of the vacuum pump. So what are the reasons for the insufficient suction of chemical hybrid vacuum pump?


1. Insufficient suction. Seals age and leak, blades wear or cannot be thrown away, vacuum pumps have too little oil, pipes leak or air intakes are blocked.


2. The device is smoking and oil is injected, and the exhaust filter is faulty.


3. The temperature is really high. Oil carbon blockage oil circuit, bearing damage, rotor and end cap wear, cooling fan damage, cooling oil pipe blockage


4. Equipment overload, motor burn. The bearing in the motor is damaged, the pump head is stuck, the motor coil is burned out, and the pump head coupling and the motor coupling are too tight.


5. Abnormal noise. Blade damage, bearing damage, end cap and rotor grinding, motor bearing damage


6. Oil spills. Seal aging, exhaust filter aging failure


7. Pipeline leaks. Sometimes pipes leak for different reasons. At this point, we need to find a professional to check whether this is the reason. If so, repair and weld quickly to avoid causing more leaks. It can also be a leak in the pump, which means there is a problem with the pump itself. We should find out where the leak is and weld it to fix it.


8. The water supply temperature is high. When the pump is used for a long time and continuous operation, this phenomenon is easy to appear in the equipment itself. At this point, we need an emergency stop to allow the equipment to rest for a few minutes and cool down.


9. In addition, the vacuum pressure is the same. The difference is the amount of traffic. If the strength is insufficient, the simple solution is to make the sucker bigger.


10. If the air leakage is large during the adsorption process, the vacuum pump flow should be increased; If the strength is not enough, the adsorption area should be increased; If the sheet is deformed with a large adsorption area, there should be multiple adsorption ports.


There are many reasons for the lack of vacuum pump suction, but no matter which one, there are solutions, so usually to master some knowledge. What's better, we should check the equipment regularly so that we can find problems and solve them in time. In addition, the vacuum pressure of the vacuum pump is the same. The difference is the amount of traffic. If the strength is insufficient, it is easier to make the sucker bigger. If the air leakage is large during the adsorption process, the vacuum pump flow should be increased; If the strength is not enough, the adsorption area should be increased; If the sheet is deformed with a large adsorption area, there should be multiple adsorption ports.
