Simple And Compact Structure Gear Oil Pump Used In Mines Field
It can give performance as transfer pump or booster pump in oil
delivery system. It can be also applied as a fuel pump for delivery
system, pressurization and injection in fuel supply system and in
all industry fields as lubricating pump.
KCB series gear pumps are mainly composed of gears, axles pump
body, pump, cap safety valve and axle-end seals etc. The heat
treated gears have the advantage of higher hardness and intensity,
and rotate with the axles inside the replaceable bearing sleeves.
All of pump's parts can be lubricated by delivered medium when
The pump is properly designed with leakage and return chute, which
lets the gears bear the least torque force and reduces load and
wear on bearings bear the least torque force and reduces load and
wear on bearings in order to raise pump's efficiency.
It is also designed with safety valve for protection against
overload. The full return flow pressure of the safety valve is
1.5times higher than the rated exhaust pressure of the pump. It can
be also adjusted within the allowance of exhaust pressure range
according to circumstances.
But please note the safety valve can't be applied as
pressure-reducing valve for long time. You may install
pressure-reducing valve separately on pipe-line if needed.

1.The reading of the pressure meter and vacuum gauge should be in
the range of the technological parameter;
2.Check whether the gland box has leakage. According to the actual
situation, tighten the packing gland; (The packing gland should not
be screwed too tight in case the gland box gets heated and seal
ring wears quickly.)
3.When abnormal noise occurs or the pump gets highly heated during
the working, should stop it to check the problem immediately;
4.Generally, the safe valves should not be adjusted. Otherwise, use
the instruments to correct it. The pressure to seal the valves of
KCB‐18.3 and KCB‐33.3 is 1.7 MPa, 0.45 MPa for KCB‐55, KCB‐83.3,
KCB‐300, KCB‐483.3. The pressure for three KCB‐200 are 0.45 MPa,
0.8 MPa, 1.4 MPa. The pressure for 2CY100/3, 2CY120/3, 2CY150/7 are
0.45 MPa and 0.8 MPa.
Check before starting pump
- Check whether the fasteners are firmly;
- Check whether the driving shaft operates flexibly;
- Check whether the valves of inlet and outlet are open;
- Check whether the rotation direction of pump is correct. (The
rotation is anti-clockwise from the view of pump side to motor.)
