Replace Rexroth AZPS Hydraulic Gear Pump Characteristic:

It mainly consists of a pair of gears supported on bearing bushings, and a pump housing equipped with a front cover and a rear cover. The drive shaft extends outward from the front cover of the pump and is sealed with a shaft sealing ring. The supporting forces on the bearings are absorbed by specialized bearing bushings; Due to the sufficient elastic force of sliding bearings, surface contact is formed instead of linear contact. As a result, the excellent wear resistance of the pump is also ensured, especially during low-speed operation. This pair of gears has 12 teeth each, which can maintain the minimum flow pulsation and noise generated by the gear pump.
Internal sealing is achieved through compensating forces, which are proportional to the output pressure. By utilizing this compensation method, optimal efficiency can be ensured. These bearings provide sealing function at the end of the gap (i.e. between the teeth that transport high-pressure oil). By inputting working pressure to the rear of the bearing, the sealing area between the gear teeth and the bearing can be controlled. These specialized seals form the boundary of this area. For these radial clearances at the top of the gear teeth, sealing is achieved by pushing the gear towards the internal force of the pump casing.

 

About Replace Rexroth AZPS Hydraulic Gear Pump 

The important task of external meshing equipment is to convert mechanical energy (torque and speed) into hydraulic energy (flow rate and pressure); The external meshing gear motor is exactly the opposite. These devices must have high efficiency to avoid generating unnecessary heat. This high efficiency is achieved through precision production processes and pressure sensitive gap seals. Moreover, in this low-noise silent pump, the dual tooth surface principle helps to reduce flow pulsation, which can be significantly reduced by 75%.
The enclosed area of the displacement gear pair is coordinated with the rotation mode of the transmission shaft, thus forming the flow characteristic curve (schematic) in the left figure. In a standard hydraulic pump, paired gears will oscillate once on this characteristic curve every time they mesh. After adopting the double tooth surface structure, the flow pulsation of this silent pump was reduced by 75% - correspondingly, the flow pulsation on downstream system components was also reduced - and the new frequency was equal to twice the base frequency. During this process, the gear pair presents a smaller backlash on the rear tooth surface, providing hydraulic sealing not only on the front tooth surface of the passive gear, but also on the rear tooth surface. In this way, liquid flow discharge is alternately generated on the front and rear tooth surfaces. Moreover, by adjusting the shape of the measuring slot, the hydraulic action line can be extended to half of the standard hydraulic pump.
