The application of concrete piston in special working conditions faces many challenges, which are mainly due to the complexity of the working conditions, the high requirements of concrete and the limitations of piston materials.
High-pressure and high-speed wear: Under high-pressure and high-speed conditions, the wear rate of the concrete piston will be significantly accelerated, thus affecting its service life and pumping efficiency.
High Temperature and Corrosive Environments: In high temperature or corrosive environments, piston materials may deteriorate or corrode, resulting in reduced performance.
Diversity of concrete composition: Concrete of different grades and compositions will cause different degrees of wear on the piston. Concrete with high grades or containing special ingredients may aggravate the wear of the piston.
Selection of wear-resistant materials: To address the problem of high-pressure and high-speed wear, wear-resistant materials such as cemented carbide, ceramics, or specially heat-treated steel can be used to manufacture the piston to improve its wear resistance and service life.
Optimize piston design: By optimizing the structural design of the piston, such as adding a wear-resistant layer and improving the lubrication method, wear can be further reduced and pumping efficiency can be improved.
Strengthen cooling and lubrication: In high temperature environments, the operating temperature of the piston can be lowered, and thermal wear and corrosion can be reduced by strengthening the cooling system and lubrication system. At the same time, choosing suitable lubricants can also effectively reduce wear.
Select pistons according to concrete composition: For concrete of different grades and compositions, pistons of different materials or structures can be selected to adapt to their wear characteristics. For example, when pumping high-grade concrete, a piston material with better wear resistance can be selected.
The application challenges of concrete piston in special working conditions can be effectively solved by selecting wear-resistant materials, optimizing piston design, enhancing cooling and lubrication, and selecting pistons according to concrete composition.
