Warm congratulations on the invention patent "A Concrete Piston Sealing Body and its Manufacturing Method" applied by our company for being authorized by the State Intellectual Property Office. The patent number is ZL 2018 1 0349896.2.
The piston of the pump truck is a key component of the concrete pump truck. When working, the hydraulic pump pushes the piston to transport the concrete out of the delivery cylinder at high pressure, and then uses the distribution rod and delivery pipe on the pump truck to transport the concrete to a certain height and distance. The average service life of a traditional polyurethane piston is only about 7,000 cubic meters. When working in high-pressure and high-temperature water environments, it is prone to local hydrolysis and collapse, causing complete functional failure. This affects the progress of the project, and in severe cases, it may cause other production accidents such as strain on the delivery cylinder.The rubber-covered concrete piston developed by our company subverts the materials and molding processes used in traditional polyurethane piston; it is made of special rubber and fabric fiber, and its outer layer is fabric fiber, which can provide excellent wear resistance; the body is high-return The high elasticity and heat-resistant special rubber ensures lasting contact stress at the lip; the bottom is a cloth layer to ensure that the product has sufficient modulus and stiffness and will not deform during installation and use.The new rubber-covered concrete piston invented by our company has been verified by many customers for more than 3 years, and its average service life exceeds 20,000 cubic meters; it reduces the frequency of piston replacement (from about 3 months to more than 6 months), and significantly reduces the consumption of consumables. The cost of using the piston. Use observable pistons to assess life cycles in advance without the risk of complete equipment shutdowns due to traditional piston breakage.We will increase the promotion of the application of new rubber-covered concrete pistons in the engineering field, so that customers can understand and use our products as early as possible, reduce costs and improve efficiency for our customers. We will continue to provide high-quality products and services to new and old users with full enthusiasm, perfect services, and a pragmatic attitude.
