The Piston Rods/ The Intermediate Rods/Piston Tie Rod
Piston rod, also known as piston tie rod, is the main accessory connecting the power end and the fluild end of the drilling mud pump, and it is also one of the wearing parts of the drilling pump. The piston rods and the intermediate rods are forged from alloy steel. After heat treatment, the strength of the product is improved. The product is CNC machined and the surface treatment is galvanized, nickel-plated or decorative chrome-plated, which can meet the different requirements of customers. The piston assembly is the main part of the fluid end of the mud pump. The discharge pressure of the mud pump is generated by the reciprocating linear movement of the piston assembly in the cylinder liner. The big end of the piston pull rod is connected to the power end of the mud pump through a clamp to transmit power; the small end is equipped with a piston, which reciprocates linearly in the cylinder liner to generate pressure. Small piston-high pressure and small flow; big piston-low pressure and large flow. Our company can produce F series, 3NB series, PZ series drilling pump piston rods of various specifications (metric, inch), the material is 42CrMo.
