Fluid End Parts are the high pressure components of a reciprocating pump-especially in fracturing pumps, mud pumps, or cementing pumps-that directly handle the fluid being pumped.
1. Valve Body / Valve Insert - Controls the direction of fluid flow
2. Valve Seat - Supports the valve and seals fluid
3. Plunger / Piston - Moves back and forth to create pressure
4. Cylinder Liner / Sleeve - The inner surface where the piston operates
5. Packing / Seal - Prevents leakage around the plunger
6. Retainer / Spring - Holds and supports internal parts
7. Crosshead / Rods - Connects to the power end for motion transfer
The hydraulic cylinder is a key wearing part of the fracturing pump, often exposed to high fatigue load, corrosion, and erosion during operation. Traditional cylinder designs are prone to stress concentration, leading to stress corrosion cracking and reduced service life.
Our hydraulic cylinders are designed with optimized internal geometry, made from upgraded materials, and manufactured with advanced processes. These improvements effectively reduce stress concentration, improve durability, and significantly extend service life in harsh working environments.
Cylinder(Fluid End)enhancement Autofrettage process, master unique process speci-fication parameters, preset 3-5 times rated pressure internal stress, balance in the actual use of high pressure fluid generated external stress, greatly prolong the service life of products. |
Internal Shot Peening Under the action of shot force, the surface material is squeezed, and the compactness is enhanced. At the same time, the tiny defects on the surface are repaired and the surface stress is further eliminated |
