Suction valve-free swing rotor oil drum pump

Abstract

The invention relates to a suction valve-free swing rotor oil drum pump. The suction valve-free swing rotor oil drum pump consists of an oil suction pipe, a threaded end cover, a gasket, a swing rotorpump body, a shaft end cover, a motor and an oil outlet pipe, and is characterized in that the oil suction pipe is connected with an oil inlet of the threaded end cover; the threaded end cover is connected with the swing rotor pump body; protruding threads of the threaded end cover are butted with a nut of an outlet of a standard oil drum; the shaft end cover is connected with the swing rotor pump body; a mechanical seal is arranged in the shaft end cover; the motor is arranged on the shaft end cover; the oil outlet pipe is connected with a pump case with threads; the inner wall of the pump case and the swing rotor compose a working coupling component for sucking and discharging engine oil; as sealing performance is good, the suction valve-free swing rotor oil drum pump has extremely highself-suction capacity and oil discharge capacity; the swing rotor is driven by a rotating shaft and an eccentric shaft to make circumferential wall attached swing on an inner cavity of the pump case;and a tongue of the swing rotor vertically swings and slides in a swing guide rail to partition the inner cavity of the pump case into an oil suction region and an oil discharge region. The suction valve-free swing rotor oil drum pump has the advantages of being high in efficiency, simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the field of fluid delivery equipment, in particular to a swing rotor oil barrel pump without a suction valve for pumping barreled engine oil. Background technique [0002] A pump is a machine that moves or pressurizes a fluid. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. The pump is mainly used to transport liquids such as water, oil, acid and alkali liquid, emulsion, suspoemulsion and liquid metal, and can also transport liquid, gas mixture and liquid containing suspended solids. [0003] Pumps can usually be divided into three categories according to their working principles: positive displacement pumps, dynamic pumps and other types of pumps: [0004] 1. Positive displacement pump [0005] The movement of the working parts causes the working volume to increase and decrease periodically to absorb and discharge the liquid, and the pressur...
