Introduction:
Drilling mud pump ceramic liner for piston and high-temperature resistant high-pressure piston ( patent products ):
The piston is a new generation of oil drilling mud pump for supporting the piston, wherein the piston core is made of high quality steel processing, using a special piston rubber nitrile rubber, heat resistance, corrosion resistance, wear resistance, root using special plastic strengthening, long service life, guiding ring using special engineering plastic, which has high tensile strength, corrosion resistance, wear resistance, low friction performance. This product and other according to API standard production piston can be fully used interchangeably. And the traditional piston, the piston has the advantages of long service life, less abrasion,reliable performance characteristics, under the same conditions, the continuous service life reaches or exceedsthe United States similar products for domestic traditional piston, at least more than 2 times. Look from the structure, the piston can enhance the lip part of the piston and the back sealing effect, centralizing functionbetter, can more effectively protect the ceramic cylinder, wherein the steel core and the cover can be reused,reducing use cost.
In addition, the use of the piston will reduce the number of replacement of piston so as to extend the service life of the piston rod.
