Modified polyurethane elastomer sand pump over-current components on the application

The successful application of modified polyurethanes on overcurrent components of sand pumps (slurry pumps / mud pumps) is inextricably linked to their excellent wear and cavitation resistance; the use of this material not only saves expensive metal materials, but also After the repair of worn parts can be recycled, the maximum cost savings, in line with the current "building a conservation-oriented society," the mainstream. For different conditions and equipment, Knight carried out a wide range of analysis and experiments, made a series of fruitful results:

1. The 4-inch mud pump used for pumping sand and silt backs the original service life of the impeller is 75-120 hours. After using the modified polyurethane elastomer impeller, the service life is 720 hours, which is 6-10 times of original life.

2. In a thermal power plant 48Sh-22 pump inlet serious pump cavitation modified polyurethane coating application, the fact that the modified polyurethane coating after 5000h operation no cavitation on the surface, while the epoxy, nylon Coating has already been destroyed.

3. A 6/4D Warman pump that delivers gold tailings to a gold mill typically has a spare part life of around 30 days and uses a modified urethane elastomer part to achieve 3 times the original life.

4. A 2-inch iron ore pump slurry pump shell cover, life less than a month, modified polyurethane elastomer for processing, the service life of up to 3 months.

5. A pump outer ring with steel - plastic composite modified polyurethane wear-resistant mouth ring, the service life of less than 300 hours from the original increased to 5000 hours.

And so on the history of the progress in the development of the times, in order to further improve the anti-wear properties of modified polyurethane, Knight researchers took a 3-year study of a new generation of modified polyurethane materials, with the further maturation of the process and the turbine successfully It is about to come to an end. In the near future, this high-performance material will surely push the life span of sand pump overcurrent components to a new level, bringing greater economic benefits to users. "Excellence, excellence endless, to provide users with quality products and services" is always the goal of Knight pursuit.
