Gear pump is divided into external gear pump and the internal gear pump.
The two gears are of different shapes of the gear pump, number of teeth is different also. One for the annular gear, can in floating in the pump body, the middle one is driving gear, and the pump body into eccentric position. Ring teeth more than driving gear tooth, driving gear drives the ring gear rotating together, use the change of the space between two teeth to conveying fluid. Another kind of internal gear pump is a ring gear < BR > the active gear tooth, two more in between the two gear is equipped with a fixed crescent clapboard, separates the inhale row space is obvious. In the discharge pressure and flow rate of the same circumstances, the appearance of internal gear pump size smaller than outer gear pump.
Gear pump 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. Gear pump process requirement is high, not easy to get exact match.
Commonly used gear pump are: CB - B type gear pump, a total of 16 kinds of specifications. CB type letters gear pump, after A B shows the pressure level, China machine tool hydraulic system pressure is divided into A, B, C level 3, the corresponding pressure is 1.0, 2.5, 6.3 MPa. Agricultural machinery with CB gear pump pressure is higher, its pressure rated is 10 MPa, maximum pressure of 13.5 MPa, speed range is 1300 ~ 1625 r/min. CB - F type high pressure gear pump, pressure rated for 14 MPa, maximum pressure of 17.5 MPa.
