Wenzhou Shengyi Machinery Manufacturing Co., Ltd. is a professional manufacturer of compressors and their spare parts.
Backup Ring支承环
The construction of the backup ring is similar to the radial ring. As the name
indicate this type of ring is used to backup all the rings when using in the high-
pressure application.
The crankshaft is connected to drive, to transfer the rotary motion.
When force lubrication is used, drilled oil passage is provided in the crankshaft.
The connecting rod is made up of forged steel for 150 kW (200 hp) reciprocating
compressor. For compressor less than or equal to 150kW, ductile iron material is
used.
Gives greater stability to the piston, eliminating piston “slap” and reducing ring wear
Permits stronger piston design and higher operating pressures.
Rod loading must be kept within the limits set by the compressor manufacturer because overloading can cause excess runout of the rod resulting in premature packing wear. This in turn leads to leakage, reduced efficiency, and increased maintenance expense.
