The role the pump cobbler and cutting ring

The role of the pump cobbler and the cutting ring, which replace the wear between the feed opening and the material cylinder, protects the service life of both. They work on the following principle: under the preload of the unfolding nut, the rubber spring is pressurised and the cutting ring fits closely to the spectacle plate. The cutting ring and the spectacle plate belong to the relative movement coupling parts, after generating wear, the rubber spring can rely on its own elasticity to compensate for the wear of the spectacle plate and the cutting ring, eliminating the wear gap.

The role of the pump cobbler plate and cutting ring.

Sealing role: they mainly work with the rubber spring, through the pressure self-balancing and rubber spring automatic compensation gap, so that the floating cutting ring has a self-sealing role, thus increasing the S pipe valve delivery pressure.

Cost reduction role: due to the role of the spectacle plate and cutting ring, they replace the wear and tear between the inlet and the material cylinder, protecting the service life of both.

The role of the pump cobalt plate and cutting ring

The spectacle plate is a wearing part and its main forms of failure are wear and tear and breakage failure. The wear between the spectacle plate and the cutting ring is abrasive wear, which first manifests itself as a blunting of the angles of the cutting ring and the spectacle plate, forming a small wedge-shaped mouth with a rounded surface. As the size of the abrasive grain increases, the wear gap increases. When the gap reaches a certain value, the construction will be affected by serious slurry leakage. However, as the pumping height increases, the impact shear of the cob plates will increase and the wear will become more severe and prone to fracture and collapse. Once damaged or failed, we must replace them in time to ensure the normal operation of the entire concrete pump truck.

Cemented carbide spectacle plates have a very high hardness as well as excellent wear resistance and are extremely widely used in concrete industrial transfer pumps. Zhuzhou Xianghao Machinery Manufacturing Co., Ltd. is a professional manufacturer, research and development, sales in one of the alloy glasses plate, alloy cutting ring, carbide glasses plate, carbide cutting ring and S pipe, S pipe valve, such as fine stone pump glasses plate, cutting ring and other concrete pump accessories. The high quantity of cobalt plate and the real price of cobalt plate have won the unanimous praise of our customers!
