&If you purchase air compressor parts from a dealer or re-export them from Hong Kong and Macao, you must identify them in a certain way. In addition, all air compressor parts imported directly from abroad have order contracts, bills of lading, waybills, packing lists and invoices. If you purchase air compressor parts from an imported company, you can ask them to show the above procedures. Otherwise, it can be judged as non-imported genuine products. The editor has compiled some key points as follows: The first inspection that needs to be done is to stop the air compressor, remove the low-pressure cylinder head plate on the upper part of the cylinder head, take out the exhaust valve assembly, pour diesel into the valve slot of the exhaust valve, and find that Diesel flows out from between the valve plate and the valve body's mating sealing surface, indicating that the exhaust valve has lost its seal. Remove the fixing nut of the valve plate, take out the valve plates, and inspect them one by one to find out the worn or severely worn parts. Secondly, the long-term repeated impact of the valve plate of the centrifugal air compressor during operation will cause the sealing surface to wear, causing low pressure. The compressed air in part of the cylinder flows back into the cylinder, reducing the effective displacement of the air compressor. Finally, it should be noted that because the low-pressure cylinder exhaust valve is not tightly sealed, when the low-pressure cylinder piston moves downward to inhale, the radiator will The compressed air in the cylinder is sucked back into the low-pressure cylinder, causing the discharge pressure of the low-pressure cylinder to drop rapidly. When the piston of the low-pressure cylinder moves upward, the pressure of the discharged air rises rapidly. The pressure rises and falls, causing the pointer of the low-pressure cylinder exhaust pressure gauge to swing. intensified. A severe rotational stall will occur in the entire diffuser flow channel. The compressor outlet pressure suddenly drops, making the pipe network pressure higher than the compressor outlet pressure, forcing the airflow to flow back to the compressor until the pipe network pressure drops below the compression level. When the outlet pressure of the machine is reduced, the compressor begins to supply air to the pipeline network again, and the compressor returns to normal. When the pressure in the pipe network returns to its original pressure, the flow rate is still less than the surge flow rate, and the compressor develops a severe rotational stall, the outlet pressure drops, and the air flow in the pipe network flows back to the compressor.
