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 and energy storage plunger pump. Background technique [0002] At present, the plunger pumps used by people are self-priming plunger pumps. The plunger pumps are all constant flow pumps. The self-priming plunger pump cannot synchronize the liquid with 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. Summary of the invention [0003] The purpose of the present invention is to provide a screw-rod-distributed energy-storage plunger pump, which solves the problem that the liquid and plunger cannot be synchronized in a self-priming plunger pump under the condition of high-frequency work. [0004] The purpose of the present invention is achieved as follows: the plunger pump includes: main shaft box, cam, driving...
