Pistons, Pistons are essential and integral components of pump trucks, requiring frequent replacement due to their vital role in machinery functionality. Expertly crafted from
top-tier materials, these pistons exhibit an outstanding service life, capable of handling up to an extraordinary 30,000 cubic meters. Our company's pistons are unmatched in
wear resistance, elasticity, and tear resistance, offering unmatched reliability. They are available in three exceptional materials: polyurethane, rubber, and rubber cloth.
The essential functions of piston sealing include:
1. Sealing the cylinder
The piston sealing ring effectively seals the cylinder, preventing any leakage of high-pressure gas and ensuring that the engine
operates seamlessly. This function plays a crucial role in minimizing automobile exhaust emissions, significantly contributing to
environmental protection efforts.
2. Maintaining the lubricating oil film
During operation, the piston sealing ring sustains a vital lubricating oil film. This film dramatically minimizes friction and wear between
the piston and cylinder liner, thereby extending the engine's operational lifespan.
3. Ensuring optimal working conditions
Collaborating perfectly with the piston, the sealing ring stabilizes the piston's position, ensuring optimal operation
within the cylinder. This harmonious synergy enhances both efficiency and performance of the engine.
