Slurry pump head part 1, Slurry pump head The professional title is the pump body and pump cover. The so-called pump head slurry pump and pump cover parts should be included. Pump body is connected to the pump rotor, through the bearing impeller, seal, bearing components connected. The pump cover is a part corresponding to the pump body and cooperates with the pump cover to form a closed cavity. Pump and pump cover inside is the slurry pump liner. Lining material generally have rubber and high-chromium alloy, generally based on mining conditions to choose the pump is lined with rubber or metal alloy. 2, SP-type slurry pump, vertical slurry pump, pump cover and shaft vertical vertical. SP type is also a single-shell pump, pump cover can be made of metal or rubber. 3, D, G type for the single-pump structure (ie without lining). Pump body, pump cover and impeller made of wear-resistant metal. Pump body, pump cover connection using a special clamping structure, the pump outlet can be arbitrarily rotated, easy installation and removal. 4, BHR, LR, MR slurry pump for the double pump shell structure, pump body, pump cover with replaceable wear-resistant corrosion-resistant rubber liner (including the impeller, the front sheath, rear sheath, etc.). Pump body, pump cover and BH, L, M pump body, pump cover common, the rotation part and the installation form and BH, L, M-type pump the same. 5, M, BH, BHP, HP, H, HH type slurry pump for the double pump shell structure, namely the pump body, the pump cover with a replaceable wear-resistant metal lining (including impeller, sheath, shield, etc.) . The pump body and pump cover are made of gray cast or ductile iron according to the pressure of things, and are vertically open and bolted. The pump body has a mouth and bracket with bolts. Pump outlet can be rotated at eight angles to install. Impeller front and back cover with a back blade to reduce leakage and improve the life of the pump to survive. 6, various types of pump imports are the degree of direction, from the direction of transmission to see pump clockwise rotation. Slurry pump work matters needing attention If there is spare pump, it is best to use two pumps in turn. If the card pump is only to repair the pump, you can add a net inlet, not to allow too much impurities into the pump, so the probability of card pump will be much smaller! Slurry pump things, the pump needs to be on land On the suction pipe on the water, but also need to start the pump. Mud pump and submerged slurry pump because of structural constraints, things need to be placed on the water above the surface, the pump into the water, it must be fixed, otherwise, the motor fell into the water will cause the motor scrapped. And because the long axis length is generally fixed, so the pump installation and use of more trouble, applications have been a lot of restrictions. Pump to be divided into two aspects of electricity and machine, for the machine, the main maintenance records before transferred out to know about it. Followed by the electrical aspects, and to understand the power of each pump motor, to his control system have a certain understanding. Slurry pump with mechanical seal of the slurry pump, shaft seal water supply must be guaranteed. Non-water-free operation, otherwise the mechanical seal will be destroyed.
