What are the common faults and maintenance methods of vacuum oil filters?

Vacuum oil filter is a device that integrates vacuum drying, separation engineering technology, condensation technology, adsorption technology and precision filtration technology. Under high vacuum conditions, it can quickly and reliably remove moisture, gas, impurities, colloid, sludge and various pigments from oil, reduce dielectric loss and acid value, increase demulsification degree, and comprehensively improve oil quality.

The vacuum oil filter can meet higher and faster optimization requirements and plays a very important role in purifying the entire oil system. The following are some common faults and maintenance methods of the vacuum oil filter:

How to solve the problem that the vacuum degree does not meet the technical standards?

● There is too much water in the oil after filtration, and there is too much water vapor in the gas discharged by the vacuum pump. This is a normal phenomenon and needs to be filtered multiple times; ● Due to the different altitudes of the use locations, the vacuum degree change is not affected under standard atmospheric pressure. The oil temperature should usually be increased to evaporate the water; ● The vacuum oil level in the vacuum pump is low, and a vacuum pump should be added; ● Due to long use time, the vacuum oil needs to be replaced when the water content increases; ● The seals of each connection are leaking and need to be checked and repaired; ● The wearing parts of the vacuum pump are worn and should be checked and replaced.

How to solve the problem of jetting when the vacuum pump is started?

●If the sealing gasket of the vacuum pump is displaced or damaged, it should be repaired in time; ●The filtered oil contains a lot of water, the oil floats up and is sucked into the vacuum pump, the oil level of the vacuum pump rises, and the vacuum oil must not be higher than the oil level line.

How to solve poor oil control or no temperature?

●The oil temperature is inconsistent with the thermometer, and the oil control needs to be adjusted; ●If the heater is burned out, broken or the contact arm does not match, the circuit should be repaired and the heater replaced.

How to solve the problem of no pressure in the oil drain pump and insufficient oil output?

● If the coarse filter is clogged, clean it in time; ● If the oil seal of the oil drain pump is leaking, adjust the oil seal gland; ● If the oil inlet pipe is clogged, suck it into the bottom of the cylinder and check it in time; ● If the oil suction pipe is too thin or the oil suction range is too deep, improve the environment in time; ● If the oil filling hole of the vacuum cylinder is clogged, clean it in time.

Common maintenance methods

● Pre-start inspection: Carefully check the oil level of the vacuum pump of the oil filter and the pollution of the oil to the environment. When the oil is turbid, the dirty oil should be discharged from the drain valve, and clean vacuum pump oil should be injected from the oil filling port of the vacuum pump to raise the oil level to the center line of the oil mark. ● After each use of the vacuum oil purifier, if there is oil in the oil collector of the vacuum pump condensation system, or the oil in the vacuum degassing tank overflows into the oil collector, the oil should be discharged in time, and then the drain valve should be closed tightly. ● When the nozzle of the vacuum degassing tank is blocked, the oil can be drained and compressed with dry air from the oil channel inlet, purged or other measures can be taken for transportation.
