Vacuum oil filters are widely used in power plants, power stations, power companies, transformer industries, metallurgy, oil refineries, petrochemicals, machinery, transportation, railways and other industries. Ideal for moisture, gas and foreign particles in liquids. The vacuum pump is a key component of the vacuum oil filter.
The operating performance of the vacuum oil filter has a very important influence. The following is a solution to the common faults of the four types of vacuum oil filter vacuum pumps to help users better utilize the field application of vacuum oil filters.
Vacuum pump oil leakage:
Oil leakage is one of the most common failures of vacuum pumps. It mainly occurs in the three positions of the vacuum pump's oil window, fuel tank seal, and motor bearing shaft seal. The main reason is that the vacuum pump is used for a long time, causing these parts to age and seal failure. This can lead to oil leakage.
Oil leakage from the oil window is caused by the aging of the vacuum pump due to the long-term use of the vacuum pump, causing cracks or the aging and failure of the adhesive between the oil window and the fuel tank, resulting in pump oil seepage. Oil seal, any aging failure will cause oil leakage; the oil tank is connected to the motor through an adapter, and the junction of the oil tank and the adapter
There is a seal ring that seals the fuel tank. If it ages, it can also cause the vacuum pump to leak oil. In addition, there is a felt pad on the adapter, which plays a role in recovering the pump oil. If it sucks up, the vacuum pump will also seep oil.
The solution to oil leakage is to replace aging oil windows, shaft seals, seals and felt pads that have been filled with pump oil. After maintenance is completed, vacuum pump should be used to flush the vacuum pump before oil filling, and the filter at the oil filling port should be cleaned with solvent to keep the fuel tank clean.
