Structure analysis of slurry pump

the pump head of slurry pump

1, m, BH, BHP, HP, h, HH slurry pump is a double pump shell structure, that is, the pump body and pump cover are equipped with replaceable wear-resistant metal lining (including impeller, sheath, guard plate, etc.). The pump body and cover are made of gray cast iron or nodular cast iron according to the pressure, which are vertically split and connected with bolts. The pump body is bolted to the bracket with a stop. The discharge outlet of the pump can be rotated and installed at eight angles. The front and rear cover plates of the impeller are equipped with back blades to reduce leakage and improve the service life of the pump

safety accidents such as fire and human life will be inevitable

2. BHR, LR and Mr slurry pumps are double pump casings. 4. The whole process is operated through the computer interface. The pump body and cover are equipped with replaceable wear-resistant and corrosion-resistant rubber lining (including impeller, front sheath, rear sheath, etc.). The pump body and cover are the same as those of BH, l and M pumps, and their rotating parts and installation forms are the same as those of BH, l and M pumps

3, D and G types are single pump structures (i.e. without lining). The pump body, cover and impeller are made of wear-resistant metal. The connection of the pump body and the pump cover adopts a special clamping structure, and the pump outlet direction can rotate freely, which is convenient for installation and disassembly

4. SP type slurry pump is a vertical slurry pump, and the pump body, pump cover and shaft are vertical. SP type is also a single shell pump. The pump body and cover can be made of metal or rubber

5. The professional title of slurry pump head is pump body and pump cover. Generally, the so-called pump head of slurry pump should include the pump body and pump cover. The pump body is mainly connected to the rotor of the pump, and the impeller, seal and bearing components are connected through bearings. The pump cover is the part corresponding to the pump body, which cooperates with the pump cover to form a closed cavity. The inside of the pump body and the pump cover is the lining of the slurry pump. The materials of the lining generally include rubber and high chromium alloy. Generally, the lining of the pump is rubber or metal alloy according to the industrial and mining conditions

6. The inlet of each type of pump is in the degree direction, and the pump rotates clockwise from the transmission direction

precautions for slurry pump operation

when slurry pump is in operation, the pump needs to be placed on land, the suction pipe is placed in water, and the pump needs to be filled and started in recent years. Due to the structural limitations of the mud pump and submerged slurry pump, the motor needs to be placed on the water surface when things happen. The pump must be fixed when it is put into the water, otherwise, the motor will be scrapped if it falls into the water. And because the length of the long shaft is generally fixed, the installation and use of the pump is more troublesome, and the application occasions are subject to many restrictions. If there is a spare pump, it is best to use two pumps in turn. If the pump is stuck, it is only necessary to repair the pump. You can add a piece at the water inlet to prevent too many sundries like BASF from entering the adidas supporting quality into the pump, so the probability of pump sticking will be much smaller

the pump should be divided into two aspects: electricity and machine. For machine, it is mainly to compare the previous maintenance records. The second is electricity. We should know the power of each pump motor and have a certain understanding of its control system. The slurry pump with mechanical seal must ensure the supply of shaft seal water. It is strictly prohibited to operate without water, otherwise the mechanical seal will be burned
