Abstract:

Vacuum filter oil machine widely used in power plant, power stations, power company, electric industry, metallurgy, oil refineries, oil chemical industry, machinery, transportation, railway industries, is processing transformer oil, turbine oil, oil, hydraulic oil, oil, gas and water in the impurity particles of the ideal equipments. Vacuum pump as vacuum filter oil of the key parts of machine, vacuum filter oil the performance of the machine has a very important impact.

Vacuum filter oil machine widely used in power plant, power stations, power company, electric industry, metallurgy, oil refineries, oil chemical industry, machinery, transportation, railway industries, is processing transformer oil, turbine oil, oil, hydraulic oil, oil, gas and water in the impurity particles of the ideal equipments. Vacuum pump as vacuum filter oil of the key parts of machine, vacuum filter oil the performance of the machine has a very important impact. The following is 4 kinds of vacuum filter oil machine vacuum pump common failure solution, in order to help users better play to the vacuum filter oil field application of machine.

 

1, vacuum pump oil leakage

The most common vacuum pump oil leak is one of the fault, mainly in vacuum pump oil window, tank gasket, motor bearing shaft seal three locations, the main cause is the vacuum pump use time is too long and cause these parts aging, seal failure, leading to the oil.

Oil leakage of oil, vacuum pump use window because time is too long and make oil window broken, or aging, cause oil and gasoline tank adhesive window aging failure, leading to pump oil leak; The motor shaft before and after oil seal on two oil seal, oil seal any aging returned to cause failure oil leakage; Tank through the adapter and motor are linked together, the fuel tank and the adapter is suggested a sealing ring, a fuel tank sealing function of aging, if it can also cause vacuum pump oil leakage. In addition, in the adapter on a mat, it felt the role of the oil pump up recovery, if it is full already, vacuum pump oil absorption will also happen oil leakage.

Finally the method to solve the oil change aging is the window, the shaft seal, gasket and already full of oil pump suction wool mat. After the completion of the maintenance, the oil pump application Edward vacuum pump oil before wash vacuum pump, and cleaning solvent oil in the mesh of mouth to note, keep clean in the tank.

 

2, less than the limit of the vacuum degree of vacuum pump

When the fault occurs, should first check vacuum system air tightness, look to whether slight leakage. Second, shall open the gas town, let the pump running in about 30 minutes to dry up the pump oil pollution can be compressed steam caused, excluding can be compressed steam to limit the influence of the vacuum.

In the exclusion of the two factors, cause less than limiting vacuum of vacuum pump are the main reasons to the following aspects: the pump oil pollution, need to change the oil; Pump oil filter in jams, cause compression note oil system supply shortage, not free, oil pump body sealing to lax, at this moment need cleaning internal oil filter; With the valve oil deformation, worn or damaged, can also lead to oil supply shortage, then should check with the valve replacement oil; Long time caused the rotary-vane vacuum pump use wear or rotor of spring tension within the insufficient, lead to breathe in room and exhaust room isolation, cause the lax vacuum pump a vacuum in performance, then drop shall be replaced rotary-vane and spring, and cleaning and pump rotor cavity; Check the vent valve, watch the action, leading to poor exhaust whether failure and, when necessary, replace the vent valve.

 

3, vacuum pump motor running stop halfway

This is because the voltage is too big and power phase lack oil level more than a lower limit, can through oil suspended, check the power supply to eliminate this situation. If the startup is not normal, it is electrical component failures, as long as replacing electrical components.

 

4, vacuum pump water

If vacuum pump water cooler water, is due to too much water is then pumped to the vacuum pump oil in the treatment of water content in the steam, not in the cooler into water and cool, through the observation into the vacuum pump on the level of the cooler water level, if too high, should be put off, should clean vacuum pump, replace the vacuum pump oil eliminate this situation.
