The common faults and solutions of vacuum oil filter are introduced
Vacuum oil filter is a collection of vacuum drying, separation engineering technology, coagulation technology, adsorption technology in one of the equipment. Under high vacuum condition, it can quickly and reliably remove the moisture, gas, impurities, glia, sludge and various pigments in the oil, and reduce the dielectric loss and acid value, improve the degree of emulsification, and improve the quality of oil. Vacuum oil filter will also encounter some faults in the process of use, then, let the small editor briefly introduce to you the common faults and maintenance methods of vacuum oil filter.
First, vacuum degree does not meet the technical standard how to solve?
1. It is normal that there is too much water in the filtered oil and too much water in the gas discharged by the vacuum pump, which requires multiple filtration.
2. Because the altitude of the site is different, it does not affect the vacuum degree change under the condition of standard atmospheric pressure. Usually, the oil temperature should be increased to make the water evaporate;
3. If the vacuum oil level in the vacuum pump is low, the vacuum pump should be added;
4. Due to the long use time, the vacuum oil needs to be replaced when the water content increases;
5. The sealing leakage of each connection requires inspection and maintenance;
6. If the wearing parts of the vacuum pump are worn, check and replace them.
Second, how to solve the spray phenomenon when the vacuum pump starts?
1. If the vacuum pump gasket is shifted or damaged, it should be repaired in time;
2. The filtered oil contains a lot of water, and the oil floats and sucks into the vacuum pump. The vacuum pump oil level rises, and the vacuum oil should not be higher than the oil level line.
Three, how to solve the problem of poor oil control or no temperature?
1. The oil temperature is inconsistent with the thermometer, so the oil control needs to be adjusted;
2. If the heater is burned out, disconnected or the contact arm does not match, repair the circuit and replace the heater.
4. How to solve the shortage of oil output without pressure in the discharge pump?
1. If the coarse filter screen is blocked, the filter screen should be cleaned in time;
2. The oil seal of the discharge pump leaks, and the oil seal gland needs to be adjusted;
3. If the inlet pipe is blocked, it should be sucked into the bottom of the cylinder and checked in time;
4. When the filling hole of the vacuum cylinder is blocked, it should be cleaned up in time.
Five, common maintenance methods
1. Check before starting: carefully check the oil level of the vacuum pump of the oil filter and the oil pollution to the environment. When the oil is cloudy, the dirty oil should be discharged from the oil discharge 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 corresponding position of the oil target.
2. When the nozzle of the vacuum degassing tank is blocked, the oil can be drained and compressed with dry air from the entrance of the oil passage for purging or other measures for conveying.
3. After each use of the vacuum oil purifier, if there is oil in the oil collector of the vacuum pump condensate system or the oil in the vacuum degassing tank spills into the oil collector, the oil should be discharged in time, and then the oil discharge valve is closed tightly.
