Abstract

A ceramic plunger pump easy to clean comprises a pump body, a rotary valve and a metering rod. The ceramic plunger pump easy to clean is characterized in that a cavity is formed in the pump body, the rotary valve matched with the cavity can be screwed into the upper portion of the cavity, and the metering rod matched with the cavity can be inserted into the lower portion of the cavity; the other end of the rotary valve is connected with a drive device, scales are marked on the metering rod, and the metering rod can move up and down; a cleaning fluid outlet, a cleaning fluid inlet, a liquid inlet and a liquid outlet are formed in the surface of the pump body; the liquid inlet and the liquid outlet are located in the same horizontal plane of the circumferential face of the middle portion of the pump body, the cleaning fluid inlet and the cleaning fluid outlet are located in the positions which are perpendicular and opposite to each other on the circumferential face of the pump body, the cleaning fluid inlet is located in the circumferential face of the upper portion of the pump body, and the cleaning fluid outlet is located in the circumferential face of the lower portion of the pump body; the pump body, the rotary valve and the metering rod are all made of acid-proof ceramic materials.

Description

field of invention [0001] The invention relates to a pump, in particular to a plunger pump. Background technique [0002] The plunger pump is an important device in the hydraulic system. It mainly relies on the reciprocating movement of the plunger in the cylinder to change the volume of the sealed working cavity, thereby realizing oil absorption and oil pressure. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment, and can be widely used in high pressure, large flow and flow adjustment occasions, such as hydraulic presses, engineering machinery and ships. [0003] At present, plunger pumps are widely used in pharmaceutical, environmental engineering, petroleum and chemical industries. Most of the plunger pumps are metal pumps. Metal pumps have the disadvantages of low hardness, poor wear resistance, poor corrosion resistance, and high temperature resistance. After the metal pump is used for a long ...
