Linsheng - Why Is The Car Air Compressor Charging Slow?
Why is the car air compressor charging slow? linsheng examples help you analyze:
A CA1091 car, after starting the engine, runs at a medium speed for about 2 minutes, and the barometer indicates that it is about 200 kPa, and the air pressure cannot rise. After checking that there is no air leakage in the pipeline, the air compressor speed is normal, the transmission is reliable and there is no slip.
(2) Reasons and analysis
The air compressor is a diaphragm type inlet and exhaust valve. Due to excessive oil, a layer of oil gel is attached to the bonding surface of the diaphragm and the cylinder head, which affects the sealing performance of the valve, so that insufficient pressure is generated.
(3) Diagnosis and treatment
When encountering slow or non-inflating, check whether the air compressor to the air reservoir pipe and joints are damaged or loose and a lot of paint. Then remove the air compressor outlet and block it with hand. If the pressure is small. Or no pressure, generally the valve leaks, the valve should be repaired.
An air compressor equipped with a loose pressure valve (such as the east windmill), if the loose pressure valve is stuck when it is opened, the intake valve cannot be closed and there is no compressed air output.
Slow inflation, but the air compressor works normally, it means that the system pipeline or the machine has a leaking part. Take the east windmill as an example, the following parts may have air leakage.
1) The front and rear brake circuit air reservoir check valve or air reservoir itself and accessories leak.
2) The connecting pipe or joint of the front and rear circuit air reservoir to the brake valve is broken and loose.
3) The brake valve intake valve leaks.
4) The relay valve seal is not leaking.
5) The connecting pipe from the brake valve to the air pressure gauge is loose and broken.
