In the case of long-distance and super-high-rise concrete pumping, the Concrete Piston needs to have a series of special performance and design features to meet the engineering needs.
First of all, good wear resistance is one of the key performances. Because the piston needs to reciprocate continuously in the cylinder of the concrete pump during long-distance and super-high-rise pumping, the stroke is long and the number of times is frequent. Therefore, the piston material needs to have extremely high wear resistance to resist the loss caused by long-term friction. For example, using high-strength polyurethane material and adding special wear-resistant additives to enhance its surface hardness and wear resistance can reduce the seal failure and performance degradation caused by piston wear and extend the service life.
Sealing performance is also crucial for long-distance and super-high-rise pumping. Under such working conditions, it is necessary to withstand higher pumping pressures, and the sealing structure of the piston must be able to effectively prevent the backflow and pressure leakage of concrete. A multi-layer composite sealing design can be used, such as a lip seal combined with a mechanical seal to ensure that a good sealing effect is maintained under high pressure. At the same time, the sealing material should have good elasticity and anti-aging properties to adapt to long-term work and pressure changes.
In terms of design features, the shape and size of the piston need to be optimized. The diameter of the piston should be precisely matched with the cylinder to ensure that sufficient pressure can be generated during the pumping process to push the concrete forward. For long-distance pumping, it may be necessary to design a piston with a slightly larger diameter to reduce pressure loss. For super-high-rise pumping, the weight of the piston also needs to be considered. It should be as light as possible while ensuring strength to reduce the energy consumption and mechanical load of the pumping system. In addition, the surface treatment of the piston is also important, such as using special coatings to reduce adhesion to concrete and prevent concrete from accumulating on the piston surface, affecting its normal operation and sealing performance. In short, with these special properties and design features, Concrete Piston can operate stably and efficiently under the complex working conditions of long-distance and super-high-rise concrete pumping.
