Structure
The utility model has the advantages of simple structure, small volume, light weight and large oil delivery. The cycloidal rotor pump adopts the structure of inner and outer rotor meshing, the number of teeth is small, the structure size is compact, and the sealing cavity can be formed without using other isolation components, and the number of parts is small.
Sports characteristics
Smooth operation and low noise. The number of teeth in the inner and outer rotors of the cycloidal rotor pump is only one tooth. When they are in relative motion, the sliding speed of the tooth surface is small, and the meshing point constantly moves along the tooth profile of the inner and outer rotors. Therefore, the mutual wear of the tooth surfaces of the two rotors is small. Since the angle of the oil absorption chamber and the oil discharge chamber are large, close to 145°, the oil absorption and oil discharge time are relatively sufficient. Therefore, the oil flow is relatively stable, the motion is relatively stable, and the noise is significantly lower than that of the gear pump.
High speed characteristics
High speed features are good. For a general involute gear pump, if the rotation speed is too high, the centrifugal force will cause insufficient filling of the valley to form a "hole", which will reduce the efficiency of the pump. Therefore, the rotation speed rarely exceeds 3000 rpm, and the peripheral speed Within 5 to 6 m / s. For the cycloidal rotor pump, the range of suction and discharge oil is large. When rotating at high speed, the centrifugal force is beneficial to the filling of the oil in the valley, and does not cause harmful "hole" phenomenon. Therefore, the rotational speed range of the cycloidal rotor pump It can be turned from a few hundred to nearly 10,000.
