Piston compressor 402ВП-4/220

Part of the compressor includes: compressor, gas coolers, cooling systems, automatic control and protection. Compressor 402ВП-4/220 – stationary, piston, crosshead, five-speed, angular, water-cooled, lubricated cylinders and glands. The compressor includes the following main knots: base, cylinders, cooling system, electric motor. The base consists of standard units crank mechanism (crankshaft, connecting rod, crosshead), frames, lubrication of the movement mechanism and lubricator. Frame cast iron, cast, box shape with internal rib strengthening. In the upper part of the frame is provided with tight fitting lids hatches providing access to the details of the movement mechanism. The lower part of the frame serves as a reservoir for oil. For mounting of the cylinders of the compressor VP-4/220 to the frame there are special bosses. In the holes of the transverse ribs is set crosshead cast-iron casings that serve as guides for the crossheads. Crankshaft is steel stamped with the cranks for installation of the connecting rod rests on roller bearings. At one end is mounted the motor rotor and fixed to the shaft end flange is made square hole for turning the compressor shaft 402ВП4/220 with the handle before starting.

At the other end of the shaft mounted gear to transmit rotation to the shaft of the oil pump of lubrication unit. The crossheads cast iron or aluminum alloy or stamped, made in concert with the sliders. With the connecting rod connects the crosshead by means of the fingers, which are produced from steel and the Assembly pressed into the crosshead. The steel connecting rods, forged, I-beam section. The connecting rod has a crank head with detachable lid and one-piece crosshead head. Detachable ear crank head with an antifriction layer of an aluminum alloy. Cover crank connecting rod connects with the rod of the connecting rod by two bolts and nuts. The compressor has one cylinder row with two and another with three stages of compression, the piston of the first stage of double action. Suction and discharge valves are fixed in the nests of pressure resistant glass and a push bolts or studs with nuts. All seals achieved using paronite gaskets. Pistons – differential made of cast iron, aluminum or steel. Piston rings – cast iron. The drive is from the single speed induction motor, built into the frame of the compressor.
