Main introduction of slurry pump
Pump body pump cover and over-current components: This series of pumps is a horizontal, vertical medium-sized, double-pump shell structure slurry pump. The pump body and pump cover are equipped with a replaceable metal lining. The lining is made of high-chromium wear-resistant alloy material. The lining can be used until wear-through, extending the maintenance period and reducing operating costs. The pump outlet direction can be rotated and installed at 8 angles.
Bearing assembly: The bearing assembly of the pump adopts a cylindrical structure, which is convenient for adjusting the clearance between the impeller and the front guard plate, and can be completely removed during maintenance. The bearings are greased.
Shaft seal (seal): The shaft seal type of the pump has packing seal, impeller seal and mechanical seal.
Transmission mode: V-type V-belt drive, flexible coupling drive, gear reducer drive, fluid coupling drive, variable frequency drive, thyristor speed control, etc. Among them, the V-shaped V-belt drive has CL, CV, CR, ZL, ZV, ZR transmission.
Overall performance: The pump has a wide performance range, good cavitation performance and high efficiency. Multi-stage series technology can be used to meet long-distance transportation. Overcurrent components are available in a variety of metals and add depth. With a variety of speeds and a variety of variants, the pump operates under optimal industrial and mining conditions. Long service life and high operating efficiency can meet a variety of harsh conveying conditions.

Centrifugal slurry pump working principle:
1. Before the pump works, the staff must first inject the liquid used for conveying into the pipeline and the pump casing, and fill the two;
2. When the slurry pump is started, the liquid in the impeller will be rotated by the blades of the impeller;
3. Under the action of centrifugal force, the liquid rotates forward and then flows out of the impeller;
4. During the process of flowing the liquid from the impeller inlet to the impeller outlet, the velocity energy and the pressure energy are increased due to the energy conversion, and the liquid flowing out from the impeller is discharged through the pump casing flow passage and then discharged from the discharge pipe;
5. At this time, the impeller inlet is formed by the discharge of water, and the liquid in the suction surface is pressed into the water inlet of the impeller under the action of atmospheric pressure;
6. The rotating impeller continuously draws in and drains water to form a continuous stream of water.
