226B Oil Pump

Product number: AZ1500070021A

Product description:

1.AZ1500070021A The oil pump is thickened for a single machine. The gear is 48.

2.Suitable for：Weichai engine, Delonghi, Auman, Jianghuai, Valin, Jess trucks.

3.The oil pump has simple structure, small size, light weight and large oil delivery capacity. The cycloidal rotor pump adopts the meshing structure of the inner and outer rotors, and the number of teeth is small.

4.Smooth operation, low noise. The number of teeth of the inner and outer rotors of the cycloidal rotor pump is only one tooth apart. When they move relative to each other, the sliding speed of the tooth surfaces is small, and the meshing point is constantly moving along the tooth profiles of the inner and outer rotors. Therefore, the mutual wear of the two rotor tooth surfaces is small. Since the envelope angle of the oil suction chamber and the oil discharge chamber is large, close to 145°, the oil suction and oil discharge time are relatively sufficient, so the oil flow is relatively stable, the movement is also relatively stable, and the noise is obviously lower than that of the gear pump。

5.High-speed characteristics are good. For general involute gear pumps, if the rotating speed is too high, due to the action of centrifugal force, the tooth valleys will be insufficiently filled with oil to form "cavities", which will reduce the efficiency of the pump. Therefore, its rotating speed rarely exceeds 3000rpm, and the peripheral speed Within 5~6m/s. For the cycloidal rotor pump, the oil suction and discharge angle range is large. When rotating at high speed, the centrifugal force is beneficial to the filling of the oil in the tooth valley, and no harmful "cavitation" phenomenon will occur. Therefore, the rotational speed range of the cycloidal rotor pump It can be hundreds to nearly ten thousand revolutions.
