High pressure coal-water slurry pump

coal slurry pump, high-pressure coal slurry pump, coal-water slurry pump

due to large coal water slurry on coal water slurry pump wear, commonly used to transport coal water slurry of coal slurry pump products are basically selects high wear-resistant mortar pump produced by aluminum alloy material, but because such products, special material cost is higher, except the coal-water slurry pump series products and often used as a high-pressure coal slurry pump used for all kinds of screw pump products products.

if the high-pressure coal slurry pump when conveying coal water slurry consumed power is too high, may be the fluid viscosity is too high, Is higher than that of choice and design of pump set size viscosity value) 。 Obviously, the higher operating pressure, the greater the power, because all rotary pump, each axis rotation flow in a week to produce the same ( Under a given pump speed, power consumption and pressure differential is directly related to) 。 Does not match the fluid may make rubber swelling, increase the interference fit between the stator/rotor, make the torque and the consumed power increases.

in the process of transmission, when the transmission distance is very long, pipeline friction loss is big, the high-pressure coal slurry pump had to do extra work to overcome the high differential pressure. At this moment need more series, because each level of the design of the differential pressure is 75 psi ( If the abrasive material content is very high, insist on lower) 。 Screw pump is too long can cause processing problems. But even if they don't consider the processing problem, a very long rotor will become soft, and prone to droop in the middle, causing large amount of interference with rubber bushing, make its overheating and failure ( Off) 。 Sometimes with a few pump, a pump to pump fluid to the opening in the middle of the storage containers, under a high-pressure coal slurry pump pumping from here on in, as shown in figure 8 3 and 8 4. This will ensure that all of the high-pressure coal slurry pump inlet pressure, the same will not rise.
