Special pump factory professional sharing: the advantages and disadvantages of special pump KCB gear oil pump

KCB gear oil pumps are generally used in construction machinery where the working environment is not clean and general machine tools with low precision, and hydraulic systems with low pressure and large flow.

Advantages of KCB gear oil pump:

1) KCB gear oil pump has simple structure, good process and low cost.

2) KCB gear oil pump is compact and compact compared to other pumps of the same flow rate.

3) The dirt in the oil has no serious effect on its work and is not easy to kill.

4) Self-priming performance is good. Self-priming is reliably achieved both at high and low speeds and even under manual conditions.

5) The speed range is large. Because the transmission part of the KCB gear oil pump and the gear are basically balanced, no large inertia force is generated at high speed.

Disadvantages of KCB gear oil pump:

1) Volumetric efficiency is low. This is due to the large leakage of the end face of the KCB gear pump.

2) Low working pressure. The gears, shafts and bearings on the KCB gear pump are unbalanced in pressure and have a large radial load, which limits the pressure increase. KCB gear oil pumps are mainly used in medium and low pressure systems.

3) The flow pulsation is large, causing large pressure pulsations, causing vibrations of pipes, valves, etc., and high noise.
