1. Details of ZKB vapor recovery vacuum pump                                                                                                                
    ZKB Series gasoline vapor recovery vocuum pump is a relatively consummate pump for oil-gas recovery, working under the ambient temperature at -40~60ºC. It can be used seperately or as a part of oil-gas recovery system in gas stations, whcih is mainly used for oil-gas recovery, to reduce pollution and save energy.

    Characteristic of ZKB series oil-gas recovery vacuum pump; a shaft drived by motor is fixed on the pump body, and its one end in the pump body is flxedly connected a crank which is jointed to a connection rod; a piston in liner with reciprocating motion is fixed on the top of the connection rod, and the liner is fixed in the pump body; a valve seat assy above the piston has inlet valve and outlet valve whcih are check valve. Besides, the inlet cavify and oulet cavify on the pump body are connected with the inlet valve and outlet valve respectively; through a pipeline, the inlet cavity is connected with the coupling of an air eliminator, and one end of the coupling is connected with the hose through the hose coupling;  the hose with internal and external casing is connected with nozzle.

    With the growing requirement on taking advantage of environmental pollutionand energy well, this oil-gas recovery vacuum pump will be aplied to this field widely.

The Spherical Roller Bearing has a double row roller, with a common spherical raceway in the outer ring, with two raceway in the inner ring and an angle of relative bearing axis. This ingenious structure make it with automatic self-aligning properties, and therefore not susceptible to shaft and bearing box seat Angle error or the influence of shaft bending, suitable for installation error or shaft deflection caused by the Angle error of the occasion.In addition to bearing radial load, the bearing can withstand the axial load of two-way.

Self-aligning Roller Bearing inside hole has two kinds of cylindrical and conical, conical taper hole taper for 1:30 and 1:12 two kinds, the conical bore bearing with set or withdrawal sets, the conical bore spherical roller bearing can be conveniently and quickly assembled on the optical axis or ladder machine shaft.


Application of spherical roller bearing: papermaking machinery, speed reducer, railway vehicle axle, gear box bearing, rolling mill rolling mill rolls, crusher, vibrating screen, printing machinery, woodworking machinery, all kinds of industrial reducer.

The types of spherical roller bearing are below:

Spherical roller bearing (20000CC);

Tapered holes spherical roller bearing (20000CCK type);

Spherical roller bearing (20000CC/W33);

Tapered hole spherical roller bearing (20000CCK/W33);

Aligning roller bearing installed on a adapter sleeve (20000CCK+H type);
