Product Description

Assembled Piston for HONGHUA Pump and Qingzhou Mud Pump  

Product Description

The assembled piston mainly consists of a piston core, piston cup, pressure plate, clamp spring, clamp ets. The piston core is forged from 45#/35 CrMo/42 CrMo. Piston rubber is vulcanized rubber products, ordinary rubber is made of nirtrile rubber, polyurethane rubber can also be used to improve the working temperature range of rubber.

During operation, piston reciprocate within cylinders, driven by the crankshaft or crosshead mechanism of the pump. As the piston moves backward, it creates suction that draws in drilling fluid into the cylinder. Upon forward movement, the piston pressurizes the fluid, forcing it through discharge valves into the drill string and borehole. This continuous circulation of drilling fluid helps cool the drill bit, remove cuttings, and maintain wellbore stability.
Our company strictly controls the production of mud pump piston assembly within the tolerance range, ensuring easy installation, wear resistance, corrosion resistance, long service life, and suitability for various harsh working environments.

 

Common Issues and Maintenance

 

 

Despite their robust construction, mud pump pistons are subject to wear and potential issues over time, including:

• Seal Wear: Leading to fluid leakage and reduced efficiency.
• Cylinder Damage: Caused by abrasive particles in the drilling fluid.
• Fatigue and Breakage: Particularly under high-pressure conditions.

Regular maintenance, including inspection of seals, lubrication of moving parts, and periodic replacement of worn components, is essential to prolong the lifespan and reliability of mud pump pistons.
