Interpretation of the structure of slurry pump, slurry pump structural characteristics

The so-called sharpening not mistakenly cut firewood workers, we use the slurry pump before installation, we must be clear about its internal structure, it will not make some very low-level mistakes. Today, Xiaobian for everyone to tell the structure of the slurry pump and slurry pump structure, I hope it can help you. (A) the structure of the slurry pump (1) pump head part 1, M, AH, AHP, HP, H, HH type slurry pump is a double pump shell structure, that is, pump body, pump cover with a replaceable resistance Grinding metal lining (including impeller, jacket, shield, etc.). The pump body and pump cover are made of gray cast iron or ductile iron according to working pressure. They 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. Front and rear impeller blades with back blades to reduce leakage and improve pump life. 2, AH slurry pump body pump cover and flow components: The series of pumps for the horizontal, vertical open, double pump structure slurry pump. Pump body and pump cover with replaceable metal lining, lined with high-chromium wear-resistant alloy material, the lining can be worn until wear, prolong the maintenance cycle and reduce operating costs. The direction of pump outlet can be rotated at 8 angles. Bearing components: pump bearing components cylindrical structure, easy to adjust the gap between the impeller and the front guard, the overall removal can be repaired. Bearing grease lubrication. Shaft seal (seal): pump seal type packing seal, pay impeller seal, mechanical seal. Transmission: a V-shaped belt drive, flexible shaft drive, gear reducer transmission, hydraulic coupling drive, frequency drive, SCR speed control. V-belt drive with CL, CV, CR, ZL, ZV, ZR drive. Overall performance: pump performance range, cavitation performance, high efficiency. Multi-stage series technology can be used to meet the requirements of long-distance transportation. Overcurrent components have a variety of metals to choose from, and increase the depth. A variety of speed and a variety of variants, making the pump run in the best mining. Long service life, high operating efficiency, to meet a variety of harsh conditions of delivery. 3, D, G type for the single-pump structure (ie without lining). Pump body, pump cover and impeller made of wear-resistant metal. Pump, pump cover connection using a special clamping structure, the pump outlet can be any direction of rotation, easy installation and removal. 4, EVM, 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 part of the general should contain. 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 forms a closed cavity together with the pump cover. 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, all types of pump imports are horizontal, from the direction of transmission to see the pump for clockwise rotation. (2) seal three kinds of seal each have their own advantages and disadvantages. First of all, packing seal, is the most common type of seal, is injected into the shaft seal water in the form, and constantly in the filler which injects a certain pressure water, to prevent the pump body slurry leakage; not suitable to pay the impeller seal multi-stage series Pump, using packing shaft seal. Packing seal structure is simple, easy maintenance, cheap. Followed by the impeller seal, through a reverse centrifugal force of the impeller to prevent slurry leakage. In the pump inlet pressure is not greater than the value of the pump outlet pressure of 10% of the single-stage pump or multi-stage tandem pump of the first pump can be used to pay impeller shaft seal, pay impeller shaft seal without shaft seals, not diluted slurry Body, good sealing effect. Therefore, in the slurry is not allowed to dilute the case, consider such a seal. Again, the mechanical seal, the general requirements of the seal is relatively high use. Especially some chemical, food fields, not only requires sealing, but most importantly does not allow additional ingredients into the pump body. The disadvantage is that the high cost, maintenance difficulties. (B) structural characteristics of the slurry pump 1, M, AH, AHP, HP, H, HH-type slurry pump for the double pump shell structure, the pump body, pump cover with replaceable wear-resistant metal lining Impellers, jackets, guards, etc.). The pump body and pump cover are made of gray cast or ductile iron according to the working pressure, 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. Front and rear impeller blades with back blades to reduce leakage and improve pump life. 2, AHR, LR, MR slurry pump for the double pump shell structure, pump, pump cover with replaceable wear-resistant corrosion-resistant rubber liner (including the impeller, the front jacket, rear jacket, etc.). Pump body, pump cover and AH, L, M pump body, pump cover common, the rotation part and the installation form and AH, 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, pump cover connection using a special clamping structure, the pump outlet can be any direction of rotation, easy installation and removal. (Editor: Huang Nengwen QQ:)
