Functional description of each component on the Oil Road
A) Oil cooler
The oil cooler and the air after cooler have the same cooling method. There are two types of air
cooling and water cooling. If the environmental conditions are not good, the fins of the air-cooled
cooler are susceptible to dust and affect the cooling effect. The exhaust temperature will be too
high and tripping. Therefore, for each period of time,
apply compressed air to dust off the fin
surface, if it cannot be blown clean, must be cleaned by solvent, and must keep the coolers
surface clea
n. When the tube and shell cooler is plugged,
it must be soaked with special potion,
and the fouling of the clogged pipe must be removed mechanically. Be sure to clean it
completely.
B) Oil filter
Oil filter is a paper type filter, whose function is to remove impurities such as metal particles,
oil degradation and so on. The filter accuracy is between 5u-10u and has perfect protection for
bearing and rotor. Whether the oil filter should be replaced or not can be judged by its pressure
difference indication and operation time.
If the pressure difference indicator light is on, the oil
filter stopper must be replaced. After the first 600 hours of operation of the new machine, the
oil and oil filters need to be replaced
, Then it will replaced according to the light or running time
of the differential pressure indicator lamp. If the pressure difference of the oil filter is large and it is
not replaced, it may lead to insufficient oil intake, and the exhaust high temperature hopper will
affect the bearing life because of the lack of oil quantity at the same time.
C) Oil separator
The filter core of the oil fine separator is made of multi-layer fine glass fiber. The foggy oil
and gas contained in compressed air can be almost completely filtered out after passing through the
oil fine separator. Under normal operation, the oil separator can be used for about 3000-4000 hours.
However, the oil products of lubricating oils and the degree of pollution of the surrounding
environment have a great impact on their life. If the environmental pollution is serious, you may
consider installing a front air filter; as for the choice of lubricating oils,
Must use our company
screw air compressor special high grade lubricating oil
, most avoid using false oil or mixed oil.
The outlet of the oil separator is provided with a safety valve and a pressure maintenance valve,
