Slurry is a mixture containing the dregs transportation of solid particles with water. But in principle, it belongs to a centrifugal slurry pump. The main components of the centrifugal impeller and casing, impeller means located within the housing shaft and the prime mover connected to form a whole. When the prime mover drives the impeller to rotate, the impeller blades rotating fluid force that the blade acting on the fluid along its direction of motion, forcing the fluid pressure potential energy and kinetic energy increases. At the same time, the fluid in the inertial force, the flow from the center to the edge of the impeller, and at high speed out of the impeller into the pressure of the chamber, and then is discharged through the diffuser, this process is called pressurized water process. If the speed is not the same range or turn, we will use to change the speed or the steering gear to enable the two to achieve the purpose of mating. When the two speed ranges, generally available to change the pulley diameter approach to regulation. Pulley diameter and speed to the formula below. (1.01 ~ 1.05) × × slurry pump slurry pump speed power machine pulley diameter pulley diameter = -------------------- power machine speed power machine speed × power machine pulley diameter slurry pump pulley diameter = ---------------- (1.01 ~ 1.05) × slurry pump speed actually selected slurry pump and power machine speed, can separately from them Performance table or on their plate, isolated, slurry and so long as there is a power machine of which can be found or pulley diameter measured, the other can be calculated according to the formula, the formula of 1.01 to 1.05 are considered belt slippage will reduce the speed of the pulley, slip coefficient achieved. Under normal circumstances, take the 1.01 to 1.02 V-belt, flat belt take nature different materials also contributed to the 1.02 parts of slurry pump worn over an important reason, it is mainly reflected in the following aspects: 1, the material concentration and flow rate when the material Under the same operating conditions, the lower the concentration of the material, the lower the material in the solids content, flushing of the solid particles of the weaker parts of slurry pump wear and tear of the little stream, the higher life expectancy and vice versa. The flow rate of the material increase per unit time of solid particles on the surface of the flow impact of the number of members increased, the greater the amount of material loss. 2, the pH of the slurry pump materials during transportation, in addition to solid particles erosion caused material losses, the pH of its materials can also cause loss of materials, corrosion and interaction in the erosion wear, Loss materials will be expanded in erosion under conditions of pH, acid groups on different pieces of different lining materials, corrosion and wear rate impact will be different. 3, the size of the material particle size, hardness and angle of impact of materials, hardness, and impact angle on the surface of the parts of slurry pump angle of impact and erosion will have a huge influence over current member. If the material is similar to the concentration and pH, solids particle size is small, the hardness is low, then the corresponding impact energy smaller solid particles, the flow over the wear member is small, can prolong the life of more than 6 times. If the impact angle is small, the material erosion increases the effective participation of the cutting forces, as well as increase the wear rate and reduce life expectancy. Slurry pump wear is mainly these areas led to, in order to reduce the wear and tear in addition to considering the above issues, the need to consider the material flow of slurry pump parts.
