Intake Valve 1622348800 features severe grooves on the valve cone. In the most serious case, after 530 hours of operation, the wear amount is up to 2.38mm.
Intake Valve 1622348800 The primary cause of wear is slide due to friction between the intake valve and the seat. This sliding is caused by the deflection of the valve and cylinder head. Under BURST PRESSURE, THE PRESSURE OF THE VALVE AGAINST THE SEAT IS VERY HIGH, AND IT CAN BE ASSUMED THAT AT VERY HIGH PRESSURE, EVEN A SMALL SLIP, DRY friction WILL CAUSE WEAR. Similarly, cylinder head, valve deformation,
why exhaust valve and seat wear is much lighter than the intake valve? This is because there is a thin nonmetallic layer on the working face of the exhaust valve and seat. These are made up of motor oil, ash and smoke particles remaining in the exhaust. It makes the air valve and valve seat face does not occur between the metal contact, so that the friction movement from damage effect, but on the inlet valve, due to the pressurized air blowing brush to prevent from the valve guide to inhale the oil on the one hand, on the other hand, the residual oil on the surface of the inlet valve and seat, ash blowing brush clean, to produce dry friction and cause damage
Intake Valve 1622348800 We have other models, all of which are used on Atlas air compressor. If the client requires it, please provide the corresponding air compressor model. We have intake valves of different sizes so that we can confirm the corresponding model
Fault analysis of intake valve of screw air compressor
1, medium with liquid or external impurities into: medium with liquid or compressor gas-liquid separator failure, will cause liquid strike on the air valve, the air valve because of additional impact and accelerated failure, mainly manifested as abnormal sound when the compressor is running. If the compressor is placed for a period of time, the liquid with the cylinder lubricating oil or medium accumulates in the cylinder, which will not only cause the erosion of the cylinder and the air valve, but also when the cold machine starts, the liquid in the cylinder is not discharged or the air valve is not cleaned, resulting in the start of the cylinder with liquid, which is easy to cause liquid strike and oil viscosity. Driven by the air flow, solid impurity particles strongly impact the intake valve of the screw air compressor, leading to parts damage, or dirt sandwiched between the sealing surface, so that the intake valve fails.
