Booster Compressor KOMPBERG BKB22
Booster Compressor KOMPBERG BKB Description
The compressor is intended for compressing air only. Its use to compress other gases requires prior agreement with machine manufacturer or vendor. Such agreement must be made in writing. The compressor may not be used for any purpose other than specified.
Booster Compressor KOMPBERG BKB Technical Description
Applications
The KOMPBERG series booster compressors are intended for boosting air pressure from 1-1.3 MPa (KOMPBERG BKB22) on the suction side, to 2.5-4.0 MPa on the pressure side. The booster is provided with an oil filter and end cooler.
Main components
The booster compressor comprises an oil piston compressor with “V” cylinder arrangement at 90° angle. The compressor is driven by an electric motor with a belt transmission. A common frame supports the compressor, motor and air end cooler with fans and filters.
The compressor
It is a one-stage, two-cylinder, one-sided compressor, with a "V" cylinder configuration and a 90 bifurcation angle.
A compressor carter with a tunnel structure is made as a cast iron cast. The lower part of the crankcase is at the same time an oil sump in which the oil suction filter is mounted. The oil filter is mounted on the oil pump.
Two cylinders with working valves are attached to the compressor's crankcase. The working valves are pressed against the heads of the head with adjustment screws through special pressure sleeves. In order to ensure more efficient heat dissipation, the cylinders and heads are suitably ribbed.
Crankshaft, cast of nodular cast iron with increased impact strength, is supported by two rolling bearings. On the one hand, the crankshaft has a conical tip for seating the pulley, while a gear-driven oil pump is driven from the other end of the shaft.
Two connecting rods with two-part thin-walled bushes are mounted on the surface hardened crank shaft.
Both cylinders on the intake are connected by a common intake manifold, and on the discharge by an air cooler.
Electric motor
The booster compressor is driven by a squirrel-cage, AC electric motor. The motor is designed for an intermittent run, for maximum 20 starts per hour. The compressor is driven by the motor via a belt transmission.
End cooler
The cooler in the KOMPBERG boosters is made of vertical ribbed steel tubes connected with horizontal collectors at the ends. The cooler has welded construction. In the upper cooler collectors, valves for draining condensate and a relief solenoid valve are provided. Air circulation in both solutions is forced by a fan driven by an electric motor.
Booster compressor frame
The KOMPBERG BKB22 booster frame, on which the motor and compressor are supported, is made of plate and seated on four shock absorbers.
