If your factory uses a Chinese-made compressor that needs to be replaced or maintained, we can provide ready-made parts and components or services (you only need to provide the factory name and model of the Chinese compressor).
The compressor can use narrow piston, due to the use of narrow piston larger valve area for greater efficiency.
Crank Shaft曲轴
Larger compressors, normally above 150 kW(200 hp), the crankshaft is made up of
forged steel. Compressor less than or equal to 150kW, the crankshaft is made up of
ductile iron.
The Figure shows a drilled crankshaft.
Crankshafts should have removable balance weights to compensate the rotary unbalance
as well as reciprocating unbalances. The crankshaft should be dynamically balanced
when above 800 rpm.
Cross Head十字头
All industrial compressors are equipped with crosshead. The crosshead is used to
guide the piston in the cylinder bore. The following are the advantage of the crosshead.
Normally the piston is made up of less weight materials such as aluminium and aluminium alloys, this is to reduce the reciprocating compressor Shaking forces and Rod load. For larger diameter pistons, hollow type pistons are used to reduce the weight.
