Each part with the locking nut on the shaft where the relative position

Slurry common tolerances and surface finish options

In selecting a part tolerances and surface finish , it must proceed from reality , combined with the production of the specific circumstances , correctly handle the precision requirements and processing economic contradictions .

Used to meet the requirements of the premise , reasonably determine accuracy class . General centrifugal pump commonly recommended tolerances and surface finish chosen according to Table 10-11 , the other pump can be made on the basis of this Tsuen appropriate modifications , Section VII multistage pump rotor mounted technical requirements of small Multistage pump rotor parts prior to assembly of the total to be small installation. After mounting the rotor of small to be checked , in order to eliminate tolerance factor , to avoid the accumulation of errors caused when the assembly tolerance phenomenon .

Small rotor mounted correctly formulate technical requirements is to ensure the safe operation of the pump an important factor . Figure 10-4 is a general multi-stage pump rotor parts diagram . slurry pump manufacturer Structure known from the rotor , the rotor is composed of many parts of packages, the composition of the shaft . Each part with the locking nut on the shaft where the relative position .

Therefore , the contact face of the parts manufacturing error ( not perpendicular to each face of ) concentrated reflection on the rotor . If the rotor runout in large parts , the pump is easy to produce in the operation of grinding. After checking if found runout tolerance , and tolerance must seriously investigate the reasons and seek to eliminate .
