Pump design mainly consider the pump material, sealing, bearings (cooling, structure, lubrication); structure, the coupling. Bearing frame. Axial force, radial force balance. Sealed form, cooled, and rinsed.
Hammer Crusher parts
Hammer crusher parts are the key parts in hammer crusher or shredders to crush hard materials such as coal, gangues, ores, limestone and bricks. It is widely used in the sand making, quarry, mining, recycling, sugar plant and brick plant. We have different kinds of materials and versatile anti-wear solutions for hammer crusher parts to be used in different applications, to maximumly save cost for customers.
We manufacture and supply high performance hammer crusher spare parts in a variety of premium metallurgies. From hammers and rollers to breakers, blow bars, impact plates, and side.

High-temperature pump designed to see what is the main transport media.
High temperature pump design should pay attention to several issues:
1, the structure of the application of intermediate support.
2, due to the strength of the material and the temperature, so the intensity should be re-calculated, check the temperature and pressure gauge of the material. Including flange, wall thickness, bolts and so on.
3, high temperature, impeller design should pay attention to cavitation erosion resistance.
4, specially designed hot or cold water chamber, starting from the seal cooling, coupling to the temperature should be down, due to the general motor temperature limit.
5, Lubrication Oil lubrication, grade and bearing box temperature matching (in fact, by bearing temperature selected lubricants).
6, seal design should pay attention to the problem of easy vaporization of high temperature liquid, easy to make machine seal appear dry friction.
7, the relevant cooling pipe design, instrumentation layout reasonable, beautiful appearance.
