Anti-seismic variable oil pump

Abstract

The invention discloses an anti-seismic variable oil pump, comprising a fixing base; positioning columns are arranged on the fixing base; an oil pump casing is connected to the positioning columns; acircular cavity is arranged in the casing; a rotating shaft is arranged at the position where the circular cavity deviates from the center of the circle; a rotating disc is arranged on the rotating shaft; a plurality of retractable blades are evenly arranged on the rotating disc; a liquid inlet and a liquid outlet are arranged in the side of the circular cavity; an annular limit groove is arrangedin the outer ring of the circular cavity on the casing; limit rods are arranged at the outer end of the blades; the limit rods slide in the annular limit groove; a vertical screw hole is arranged onthe fixing base; a screw rod is arranged in the vertical screw hole, and the screw rod has opposite threads at both ends; a hexagonal convex ring is arranged in the middle of the screw rod; the upperthreads of the screw rod is matched with a lifting seat; a horizontal through hole is arranged on the lifting seat; a waist hole is arranged on the end surface of the casing; the rotating shaft is rotatably connected to the lifting seat; and a pulley is further arranged on the rotating shaft. According to the anti-seismic variable oil pump, the mechanical efficiency of operating in a vibrating environment is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of oil pumps, in particular to anti-vibration variable oil pumps. Background technique [0002] A variable displacement oil pump is an oil pump with variable displacement. Widely used in hydraulic transmission fields such as metallurgy, mining, engineering machinery, ships, civil aviation ground equipment, etc. [0003] The existing vane-type variable oil pump generally changes the flow rate of the oil pump by changing the eccentricity. Generally, the vane-type variable oil pump includes a shell, which is provided with an oil inlet, an oil outlet, and an oil chamber. There is an adjustment ring, and a rotating shaft is arranged inside the adjusting ring, and telescopic blades are evenly arranged on the rotating shaft, and the blades are pressed against the adjusting ring by spring thrust, and the size of the cavity between the blades is changed by the rotation of the rotating shaft. , to realize the extrac...
