Plungers are mainly used in pumps or compressors to transport fluids. The plunger is assembled in a long cylinder and can move forward and backward (push-pull). The gap between the plunger and the cylinder is fitted with a suitable seal. When the plunger is pulled back, the fluid in the cylinder is pressed and sent out from the outlet pipe, the plunger keeps reciprocating in the cylinder, and the fluid is continuously transported to the target mechanism, which is the function of the plunger . The traditional plunger is made of metal, which is easy to wear, has a short life, and has poor reliability; ceramic plungers have the advantages of wear resistance, corrosion resistance, high temperature resistance, etc., and are widely used in fracturing pumps, injection pumps, cleaning pumps, metering pumps, pumping Oil pumps and complex working conditions in other fields.
The ceramic plunger adopts high-performance technical ceramic material, which has the properties of high hardness, wear resistance, high temperature resistance and corrosion resistance. To ensure reliable material performance.
The microporous structure obtained by the unique processing method of the ceramic plunger working surface has a self-lubricating effect, which changes the sliding friction and lubrication mechanism of the traditional plunger pump.
The surface of the inner cavity adopts a fluid structure without dead ends and grooves. The surface of the inner cavity and the surface of the plunger are processed to a mirror surface by an advanced high-precision inner and outer cylindrical grinder, and the outer surface is vibrated and polished, which is convenient for cleaning and disinfection.
The structure of the pump body is finely sealed with the product structure, which is convenient for disassembly.
This type of product has been tested for corrosion resistance, acid and alkali resistance, and its various indicators have reached the level of similar foreign products.
The ceramic plunger meets the comprehensive working conditions of pressure, temperature, wear and corrosion. Under the same working conditions, the service life is 5-10 times that of the ordinary metal plunger;
Plunger type reciprocating pumps in various industries: oil field water injection, coal mine emulsion pumps, mud pumps, nuclear power cooling pumps, etc.
