Slurry pump head part 1, M, BH, BHP, HP, H, HH-type slurry pump for the double pump shell structure, the pump body, the pump cover with a replaceable wear-resistant metal lining (including the impeller, Jacket, 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.
2, BHR, LR, MR slurry pump is double pump shell structure, pump body, pump cover with replaceable abrasion and corrosion resistant rubber lining (including impeller, front jacket, rear jacket, 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.
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, 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.
5, slurry pump head 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.
6, various types of pump imports are the degree of direction, from the direction of transmission to see pump clockwise rotation.
Slurry pump operation note Matters Slurry pump things, the pump needs to be placed on land, 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.
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 excessive impurities into the pump, so the probability of card pump will be much smaller!
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. The use of mechanical seal of the slurry pump, shaft seal water supply must be guaranteed. Non-water-free operation, otherwise the mechanical seal will be destroyed.
