Internal Gear Pump Specific Structure And Use

Gear pump is divided into external gear pump and internal gear pump. Internal gear pump two gear shapes are different, the number of teeth is not the same.

Internal Gear pump specific structure and use

Gear pump is divided into external gear pump and internal gear pump. Internal gear pump two gear shapes are different, the number of teeth is not the same.

One of them is a ring gear, which can float in the pump body, the middle is a driving gear, and the pump body into an eccentric position.The ring gear has one more tooth than the driving gear.

The driving gear drives the ring gear to rotate together. USES the change of space between the two teeth to transfer liquid.

Another type of internal gear pump is the ring gear more than the driving gear two teeth. Between the two gears with a fixed crescent shaped partition, the suction space is clearly separated. In the same discharge pressure and flow, the external size of the internal gear pump is smaller than the external gear pump.

Gear pump used for conveying meaning viscous liquid. Such as lubricating oil and burning oil, unfavorable delivery low viscous liquid, such as water and gas, etc. Should not be conveying liquid containing granular impurities (affect the service life of the pump).

Oil pump can be used as lubrication oil pump and hydraulic pressure system, widely used in the engine, steam turbine, centrifugal compressor, machine tools and other equipment.

SUS 316L stainless steel gear pump process requirements, not easy to obtain accurate matching. Commonly used gear pump are: KCB gear pump total of 16 specifications.The model letter CB stands for gear pump, and the latter B for pressure level.

The pressure of Chinese machine tool hydraulic system is divided into A, B and C levels. Corresponding pressure is 1.0, 2.5 and 6.3mpa. WCB gear pump for agricultural machinery has high pressure. Rated pressure of 10 MPa, maximum pressure up to 13.5 MPa, speed range of 1300 ~ 1625r/min.

Cb-f high pressure gear pump, rated pressure of 14 MPa, maximum pressure up to 17.5MPa.
