Excavator 26004-lzh Rotary Vickers Gear Pump

Description:

The gear pump has a pair of meshing gears, gear (wheel) fixed on the drive shaft and the shaft end of the gear pump extends out of the casing is driven by a prime mover, a gear pump (driven) mounted on the other axis, the gear rotation of the gear pump, the liquid into the suction space along the suction pipe, along the upper and lower shell wall by two gears are respectively extruded into a discharge space (tooth and tooth before confluence), and then enter the pressure discharge tubing. The main features of the gear pump are compact structure, small volume, light weight and low cost. But compared with other types of pumps, it has the disadvantages of low efficiency, large vibration, large noise and easy wear.

Features:

VICKERS gear pump is divided into external and internal gear pump gear pump. The two gears of the inner gear pump are different in shape, and the number of teeth is different. One of them is a ring gear, which can float in the pump body, one in the middle is an active gear and an eccentric position with the pump body. The number of ring teeth is more than that of the active gear, and the active gear drives the ring gear to rotate together, and the liquid is transported by the change of the space between the two teeth. Another kind of internal gear pump is a gear ring gear <BR> two teeth, with a fixed crescent partition in two gear, the suction space clear off the. In the case of the same discharge pressure and flow, the shape of the inner gear pump is smaller than that of the outer gear pump.
