Is the temperature of the Kato vacuum pump casing working high and normal?

Answer:

Hello, screw vacuum pump, high temperature outlet for the following reasons:Coolant level is too low;

Breaking oil solenoid valve, or coil damage or electromagnetic valve diaphragm rupture or aging, oil breaking solenoid valve generally appear in the old models;Cooling fan motor fault;The exhaust duct is not unblocked or the exhaust resistance (back pressure) is large;The ambient temperature exceeds the specified range (38 degrees C or 46 degrees C).Hope to be of help to you.

Oil cooler is dirty, how to determine whether the cooler dirty, mainly to see the oil inlet temperature and the temperature difference between the oil inlet temperature, normal temperature difference between 20 - 30 degrees, if the external dust clogged radiators with compressed air blow static can, such as blowing off, you need to use the internal dirty radiator professional cleaning agent for cleaning; if you need to use an internal radiator blockage, water pump cleaning, cleaning time depending on the situation; such as water-cooled radiator is blocked, the best way is to cover with iron bars to clean the copper pipe before and after oil filter clogging apart; also can cause the screw type air compressor fault;
