Assembly of multi-stage diesel pump

1. Preparation before assembly of multi-stage diesel pump

(1) All kinds of tools and multi-stage diesel pump parts, bolts and nuts are well placed.

(2) Read the product manual of the multistage diesel pump carefully to understand the assembly sequence and method of the multistage diesel pump.

(3) clean up the assembly site of the multistage diesel pump.

(4) check the replacement of multi-stage diesel pump parts size is consistent, such as mechanical seal model, bearing model, the size of the impeller and the old parts are consistent.

2. Assembly and inspection of multi-stage diesel pump impeller part

We take the multi-stage multi-stage diesel pump impeller assembly and multi-stage multi-stage diesel pump maintenance as an example.

Multi-stage multi-stage diesel pump impeller is composed of a number of impellers set on the pump shaft.

Then, they are fixed on the relative bearings of the shaft with impeller lock nuts.

If the modified parts can not meet the requirements, and the formation of a larger radial runout, the pump in the process of operation is prone to friction, damage to the normal operation of the pump.
