How to replace vacuum pump parts

At present, the quality and precision of vacuum pump parts are uneven. In order to reduce the cost, some customers use outdated materials and accessories to replace them. Long term operation is extremely unfavorable to the pump performance. Therefore, before replacing the spare parts, technical inspection is required to ensure that the quality of the new parts meets the requirements. At the same time, if the vacuum pump parts have problems, they must be replaced Parts, then, what are the requirements of vacuum pump manufacturers for parts replacement? How should we replace them properly?

First of all, let’s know what are the spare parts of the vacuum pump, as follows:

1. Sealing kit of vacuum pump. After long-term use of vacuum pump, the sealing kit will be damaged after the pump body is removed.

2. Oil mist separator of vacuum pump. The oil mist separator of vacuum pump injects oil and emits black smoke. In fact, the oil mist separator of vacuum pump has failed, and the purpose of separating pump oil and gas cannot be achieved. As a result, a small amount of vacuum pump oil and a large amount of black smoke are ejected from the exhaust port of vacuum pump, which is also one of the main parts for repairing and maintaining vacuum pump.

3. Vacuum pump oil filter, one of the pump accessories, is mainly used to filter unknown foreign matters such as impurities in the oil, so as to protect the vacuum pump. If unqualified vacuum pump oil is used, the vacuum tip oil filter and oil mist separator will be easily damaged, resulting in greater losses.

4. Vacuum pump oil, vacuum pump oil is one of the commonly used consumables that must be replaced in the maintenance of vacuum pump. The pump oil is also the place where impurities are unknown. If one of the core consumables of vacuum pump is not replaced or added with special vacuum pump oil immediately, it is very easy to damage the normal operation of vacuum pump.

5. Bearing, shaft seal, vacuum pump running at high speed due to pump start-up will cause sudden high-speed operation of vacuum pump, bearing in such a long-term use will continue to wear and depreciation, resulting in damage failure, if the bearing failure, the rotor of vacuum pump will be slightly offset, resulting in increased friction between blade and cylinder, which will damage the blade.

6. If the noise increases during the long-term use of the vacuum pump, the damage of the blade or the increased friction caused by the unknown object entering the cylinder block can be considered. If such problems are solved in time, the problem will not increase.

What are the requirements for the replacement of vacuum pump parts? In fact, it is very simple, that is, the parts need to be thoroughly cleaned before the parts are replaced. In the vacuum pump maintenance, especially in the poor maintenance environment, we need our maintenance personnel to try our best to ensure that the equipment is clean.

In addition, the correct selection of cleaning agents, the use of alkaline cleaning agents, to prevent corrosion and rust parts, especially those precision parts. In addition, aluminum and copper parts are not easy to be cleaned in alkaline detergent, rubber parts and other steel parts should not be cleaned together with other steel parts in gasoline, diesel, acid and alkaline cleaner.
