BALDOR AIR COMPRESSOR
b、system flow chart
Air compressor process includes air system, lubricating oil system and cooling system.
1 air system process
After air into the air filter removing dust, it is compressed in the air end through the inlet valve. The
compressed oil mixing with air go into the oil-air separator, then the filtered air go through the minimum
pressure valve, cooler, air water separator, and finally discharge by the air-supply valve (air water
separator can be installed after the air supply valve, according to the needs of users). The separated oil
stays in oil-air separator tank, then go into the oil circulation system.
2 lubricating oil system process
Lubricating oil system is composed of oil and gas separator, temperature control valve, oil cooler, oil
filter, etc. The oil in oil-air separator is driven into oil pipe under the air pressure, then goes through the
temperature control valve, oil cooler and the oil filter, finally is divided into two flows, one flow injecting to
air end, another flow into the front and back bearing to lubricate the bearing. The two flows are combined
in the air end, mixing with the air, going into the oil-air separator, separated by the oil-air separator, staying
in oil-air separator, and into the next cycle.
