| Zusammenfassung: | The utility model discloses a hydraulic pump and aims at providing the hydraulic pump which can realize zero delivery and automatic control. The hydraulic pump comprises a main shaft, a pump body, a center rod, a bearing, a plunger, a cylinder body, an oil distributing pan, a small flow rate limit screw, a large flow rate limit screw and a regulator, and is characterized in that the included angle between the cylinder wall of the pump body on the side of the small flow rate limit screw of the pump body and the main shaft is 180 degrees. An electromagnet is arranged on the regulator, and the output flow rate of the hydraulic pump can be changed by changing the magnetism of the electromagnet. The delivery volume is changed from 160 ml/r to 170 ml/r through the improvement of the utility model. The hydraulic pump is mainly used for hydraulic systems of metal section material extruding machines. |
