Abstract

A spiral rod oil distribution energy storage plunger pump belongs to hydraulic pumps. A spindle box body of the plunger pump is connected with a plunger pump box body, and a driving bevel gear and a cam are installed on a spindle in the spindle box body. A plunger is installed in a plunger pump cavity of the plunger box body, a sliding wheel is arranged at the top of the plunger, a spring is installed in the middle of the plunger, and a cylinder sleeve is connected onto a plunger cavity body at the lower portion of the plunger. A driven bevel gear, a flange, screw rod bearings, an upper gasket, an oil seal and a lower gasket are sequentially connected onto a spiral rod, the spiral rod bearings are connected to the bottom of the screw rod and to the position between the upper gasket and the flange, and a spiral rod cavity screw is connected to the bottom of the spiral rod cavity. An input one-way valve spring is arranged on an input one-way valve, an output one-way valve is installed at the lower half portion of the plunger box body, a sliding plug and a sliding plug spring are installed in an energy storage safety valve, a pressure regulating hollow screw is installed at the top of the energy storage safety valve, and a normal work liquid outlet and a hyperpressure liquid outlet are arranged on the energy storage safety valve. The spiral rod oil distribution energy storage plunger pump has the advantages that a fly wheel is installed on a shaft head of a power machine, acting can be achieved by means of inertia kinetic energy of the fly wheel, and energy is saved.

Description

technical field [0001] The invention relates to a hydraulic pump, in particular to a screw rod oil distribution energy storage plunger pump. Background technique [0002] At present, the plunger pumps used by people include self-priming plunger pumps, and the plunger pumps are all constant flow pumps. The self-priming plunger pumps cannot synchronize the liquid and the plunger under the condition of high-frequency work, and the oil supply efficiency is low. At the same time, it cannot absorb the inertial kinetic energy in the working process, and has no energy-saving performance. Contents of the invention [0003] The purpose of the present invention is to provide a screw rod oil distribution energy storage plunger pump to solve the problem that the liquid and the plunger cannot be synchronized when the self-priming plunger pump works at high frequency. [0004] The purpose of the present invention is achieved in this way: the plunger pump includes: main shaft housing, ca...
