Giving you the parts of an IR horizontal single-stage single-suction centrifugal pump, can you assemble them? Or to you a complete IR horizontal single-stage single suction centrifugal pump, you will disassemble it?
IR horizontal single-stage single-suction centrifugal pump should be checked before assembly of parts have no affect the assembly defects, and scrub clean before assembly.
1, will be around the connecting bolts, plug, etc. were tightened in the corresponding parts.
2, the 0 ring, paper pad, felt, etc. were placed on the corresponding parts.
3, the seal ring and packing, packing ring, packing gland, etc. are installed into the pump cover.
4, the rolling bearing mounted on the shaft, and then loaded into the suspension, and then close the gland, bearing pressure on the rolling, and set the shaft on the connecting bolts.
5, the shaft sleeve on the shaft, then the pump cover mounted on the suspension, and then the impeller, stop pad Wai, impeller nuts, etc. installed and tightened.
6, Finally, the above components into the pump body, and tighten the pump body, pump cover bolts.
In the above assembly process, some small parts, such as flat key, gear oil pan, gear shaft, o-ring seals and other easy to escape or wrong order, should pay special attention.
Know the order of the pump assembly, demolition is also much easier, pump disassembly order can basically reverse the order of the assembly.
Machinery shell with gearbox shell processing
Machinery for typical gearbox shell body parts, main processing plane and hole system, to ensure that the size of the hole in the process of machining precision and position accuracy, handle the relationship between hole and plane. Should follow the principle of surface before hole, namely first processing box on the datum plane, and then to datum plane positioning processing other plane, then processing hole system. Because of the planar area is large, with its positioning can ensure reliable positioning, clamping and firm, and therefore easy to guarantee machining precision holes. Secondly, cut off the casting surface uneven, create conditions to improve the machining precision of holes, facilitate and adjustment of the knife, is conducive to protect the cutting tool. Processing technology should also follow the principle of separate rough finish machining.
