| Zusammenfassung: | The utility model discloses a hydraulic pump and aims at providing the hydraulic pump with low noise, stability and high pressure resistance. The hydraulic pump comprises a main shaft, a pump body, a center rod, a bearing, a plunger piston, a cylinder body, a fuel distributor, a small flow rate limit screw, a large flow rate limit screw and an adjuster. The hydraulic pump is characterized in that the included angle between the cylinder wall at the side of the small flow rate limit screw of the pump body and the main shaft is 167 degrees and 83 minutes. The adjuster is provided with an electromagnet and the output flow rate of the hydraulic pump can be changed by the change on the magnetic property of the electromagnet. The hydraulic pump is mainly used for a hydraulic system of a metal sectional bar extruder. |
