Model No.: PISTON
Piston rubber cup for mud pump is a kind of rubber cup. Used for mud pump piston, reciprocating motion seal in mud and crude oil medium. There are two kinds of packaged piston cup and integral piston. The former is made of oil-resistant rubber lip and nylon root, and is made of NBR and PU. The working pressure is 19.6 MPa and the working temperature is - 20 ~+80 C.

Piston and cylinder liner (some without cylinder liner and directly with the inner wall of the liquid cylinder) ,sealing elements are assembled on the piston assembly. The reciprocating motion of the piston alternately changes the volume of the working chamber and realizes the process of pumping, sucking and discharging by means of the pump valve. Therefore, piston must have: (1) good sealability; (2) sufficient strength and stiffness; (3) the connection between positioning of piston body and piston rod, piston ring should be firm and reliable.
Piston assembly is one of the main parts of the hydraulic end system of mud pump, and also one of the vulnerable parts in drilling work. The discharge pressure of mud pump is generated by reciprocating linear movement of piston assembly in piston. The piston assembly is composed of piston core, rubber sheet, clamp spring, pressure plate, etc. The material of piston core is 42CrMo, and the material of piston rubber is nitrile rubber or polyurethane rubber.
Nitrile Butadiene Rubber (NBR) : It is suitable for ordinary drilling environment with working pressure below 20 Mpa and working temperature not higher than 120 C. It has excellent wear resistance, chemical corrosion resistance and long service life in common drilling environment.
Polyurethane rubber: It has excellent oil resistance and wear resistance. The working temperature is not higher than 120 C. It is suitable for oil-based mud with working pressure below 35Mpa and working environment with high sediment content.
Hydrogenated nitrile butadiene rubber(HNBR) : suitable for high temperature, high pressure, high corrosion working environment, working pressure 75 Mpa, working temperature up to 150 C. Hydrogenated nitrile-butadiene rubber is a kind of rubber used in aviation. Hydrogenated nitrile-butadiene rubber (HNBR) is used in petroleum industry. It has good abrasion resistance, oil resistance and chemical resistance. It has good amine resistance and steam resistance. Especially in the high temperature and high pressure working environment, other rubber destroyed quickly under the action of hydrogen sulfide, carbon dioxide, methane, steam and acid, but hydrogenated nitrile-butadiene rubber showed good comprehensive properties.
