Valve气阀
Reciprocating compressors generally use one of three types of valve configurations:
The compressor can use narrow piston, due to the use of narrow piston larger valve area for greater efficiency.
If rod packing cooling needed, the stuffing box is jacketed for liquid coolant.
Reciprocating Compressor Basics Components
Gives greater stability to the piston, eliminating piston “slap” and reducing ring wear
Permits stronger piston design and higher operating pressures.
Rod Packing活塞杆填料
Rod packing is required to prevent the gas leakage along the piston rod where it
passes through the crank end cylinder closure.
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.
