Why does the vacuum pump of the vacuum oil filter spray oil?
The vacuum oil filter is designed according to the different boiling points of water and oil. It is composed of the fine filter, condenser, primary filter, water tank, vacuum pump, exhaust pump and electric cabinet. The vacuum pump draws out the air in the vacuum tank to form a vacuum. Under the action of atmospheric pressure, the external oil goes through the inlet pipeline into the primary filter to remove the larger particles and then into the heating tank. After heating, the oil of 40~75℃ passes through the automatic oil bleeder valve, which automatically controls the balance of the oil quantity entering the vacuum tank. Vacuum oil filter vacuum pump is easy to appear oil injection phenomenon, how to encounter oil injection? Small make up to tell you!
I. The processed oil is higher than the vacuum oil filter or the vacuum oil filter has no oil balance device
1. If there is an oil balance device in and out of the vacuum oil filter: if the processed oil is higher than the vacuum oil filter, the oil inlet solenoid valve will automatically shut down and stop the oil inlet in case of sudden power cut or the filter element plugging alarm and shutdown.
2, if be processed oil is higher than the vacuum filter oil machine, in a sudden power outage or vacuum filter oil machine filter clogging alarm when stop, due to be processed oil is higher than the vacuum filters oil machine, processed oil under the condition of the dead weight, will overwhelm the vacuum filter oil machine, when the space in the vacuum filters oil machine is full, will follow the outlet pressure of the vacuum pump oil.
Ii. Infrared defoaming damage or no infrared defoaming device of vacuum oil filter
: 1, if there are infrared defoaming device is processed oil after heating, into the high negative pressure vacuum oil-water separation devices, because the water is contained in the heated oil, the heated oil down from a sprinkler on the spray, can produce a lot of bubble, when the bubble rise to high infrared control, infrared signal is given, the intake solenoid valve will automatically open, and keep air inlet delay (adjustable), reduce the vacuum degree of vacuum oil/water separation equipment, reduce the oil bubble in the vacuum oil/water separation equipment rapidly.
2, if there is no infrared defoaming device: processed oil after heating, into the high negative pressure vacuum oil-water separation devices, because the water is contained in the heated oil, heated oil from the spray thrower in from above spray, can produce a lot of bubble, the bubble will quickly rise to the top of the vacuum oil/water separation equipment, pump, vacuum pump oil phenomenon.
So you should know how to deal with this situation when you encounter it!
