The polyurethane piston for concrete pump is a new type of sealing material, which can replace the traditional rubber piston in the process of concrete pump delivery.
Compared with rubber pistons, polyurethane pistons have the following advantages:
1. Strong wear resistance: The polyurethane piston has high wear resistance and can withstand high-frequency impact and friction for a long time, prolonging the service life of the concrete pump.
2. Good tensile fatigue resistance: the polyurethane piston has strong elastic recovery force, has good tensile fatigue resistance, can keep running for a long time, and is not easy to stretch and deform.
3. Good sealing performance: the polyurethane piston is matched with the pump body, and the sealing performance is very good, which can reduce the occurrence of water leakage and blockage.
4. Strong corrosion resistance: Polyurethane piston has good corrosion resistance, which can resist corrosion effects such as alkaline substances in concrete and steel bar corrosion, and improve the service life of concrete pumps.
The scope of application of polyurethane pistons for concrete pumps:
Polyurethane pistons are widely used in concrete pumps, mud pumps, oil mining equipment and drilling equipment and other fields. In the process of concrete conveying, underground work, construction engineering and mining, polyurethane piston can effectively improve the service life and work efficiency of equipment, and is of great significance for improving project quality and efficiency.
