Three Common Faults of Water Ring Vacuum Pump

The Water Ring Vacuum Pump has the most compact application in the actual production because of its compact structure, easy operation, and strong adaptability to the environment. However, in the actual production and use of the water ring vacuum pump, its existing problems are restricted. Effective use of itself. Therefore, it is very necessary to carry out in-depth research and analysis on the common faults of the water ring vacuum pump. We learned a few things from Water Ring Vacuum Pump Suppliers.

Water accumulates in the air inlet and outlet pipes. During the operation, the water ring vacuum pump and the steam condenser are connected. The pipeline may produce water vapor accumulation due to the working leak of the water vapor separation equipment. After the water ring vacuum pump stops running, water vapor will gradually condense and eventually become water accumulation. The water accumulation may be less at one time, but after many times, the water accumulation will increase, and may eventually flow back to the vacuum pump, resulting in an instantaneous voltage If it is too large, it will burn the motor. Maintenance treatment of water accumulation in the inlet and outlet gas pipelines: First of all, in daily work, the water ring vacuum pump should be regularly inspected, focusing on whether there is water accumulation in the inlet and outlet gas pipelines, and timely cleaning up not much water accumulation. In order to prevent such failures from happening again, the water-gas separator of the water ring vacuum pump must be modified and improved, such as using high-quality steel with higher wear resistance and corrosion resistance, or adding the diameter of the water-gas separator tube. Coarse, providing more space for water vapor separation, etc., thereby reducing water vapor accumulation and eliminating and preventing water accumulation failure.

If the motor starts abnormally or overheats, first the motor starts abnormally. "Abnormal" refers to excessive noise or failure to start, the reason may be the presence of foreign objects in the pump (in the impeller drag distribution plate), the motor supply voltage is low, and the motor lacks equal problems. Based on this, check the wiring of the motor to avoid problems such as phase failure or power failure; if the vacuum pump has not been running for a long time, in addition to the rust removal of the open end cover, the rust remover should be added inside; if necessary, the end cover should also be opened , Check whether there is debris inside, adjust the distance between the distribution plate and the impeller. Secondly, the motor is overheated. There are three reasons: one is that the water supply of the vacuum pump is too large, which in turn generates a large motor load; the second is that the motor has a missing phase; the third is that the exhaust hole is blocked. In view of this, carefully check the size of the vacuum pump's exhaust volume. If the amount of water involved is large, the water supply valve should be adjusted appropriately (smaller); the electrician should fully check the motor to avoid the lack of phase problems; carefully check the exhaust hole, if There is a problem such as unblocking, which needs to be cleared.

Vacuum Pump cavitation. During the operation of the vacuum pump, the most common failure is the damage of the impeller rotor. The main cause is that there are many pits and holes on the surface of the blade. In severe cases, the blade will break, causing unplanned equipment outages. The normal operation of production. The main cause of these failures of impeller blades is cavitation. The main reason for cavitation is that during the operation of the vacuum pump, there are alternating changes in the negative pressure area and the positive pressure area, which is determined by its structure and operating principle, so if you want to reduce or even avoid the harm of cavitation, you need Improve it in structure; In addition, some measures can be taken according to its operating principle. To prevent the water ring vacuum pump from working in the cavitation state, the measures that can be taken are mainly in two aspects: one is the improvement of the pipeline equipment, such as adding an atmospheric ejector and a cavitation protection tube; the other is based on the occurrence of cavitation Principle, take corresponding improvement measures, such as reducing the temperature of the working fluid, replacing the working fluid, and selecting the correct type.

In actual production, in order to reduce the impact of various failures on production, in addition to the various measures mentioned above, it is also necessary to strengthen online inspection and take corresponding measures to deal with problems in time. After the pump stops running, the working fluid in the pump body should be cleaned up in time to avoid scaling of the pump body affecting the performance of the pump and subsequent use.
