Abstract

The invention provides an uninterrupted water supply plunger pump. A sliding plug cavity, a first sub water inlet cavity, a second sub water inlet cavity, a main water inlet cavity and a water outlet cavity are formed in a plunger pump device; and one-way valves achieving blocking or communicating in the water flow direction are arranged between the first sub water inlet cavity and the main water inlet cavity, between the second sub water inlet cavity and the main water inlet cavity, between the water outlet cavity and the first sub water inlet cavity and between the water outlet cavity and the second sub water inlet cavity. The uninterrupted water supply plunger pump is compact in structure, convenient to assemble, capable of achieving uninterrupted water supply and wide in application range.

Description

technical field [0001] The invention relates to a pump, in particular to an uninterrupted water feed plunger pump. 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. Pumps can usually be divided into three categories according to their working principles: positive displacement pumps, dynamic pumps and other types of pumps. In addition to classification by working principle, it can also be classified and named by other methods. For example, according to the driving method, it can be divided into electric pumps and water wheel pumps; according to the structure, it can be divided into single-stage pumps...
