Test stand for pumps of mobile gas and oil pipelines machines

 

Pumps test stands are used for acceptance tests after routine and capital repair for Komatsu machines, specified in the table below.

The stand allows to do the following:

  • run in pumps without pressure;
  • determine pump flow after load change;
  • check the pump for functioning at nominal pressure and constant drive shaft rotation speed;
  • check for external leakage (visual);
  • check pump inlet rating.

The stand comprises test unit and electric cabinet. The test unit includes drive motor, bearing assembly, hydraulic reservoir, oil cooler, secondary pump, control and measuring hydraulic equipment assembled in one housing.

Apart from the hydraulic units specified above, the stand can be used to test any hydraulic units which fit stand capacities. Cheltec is able to design and manufacture any necessary adapters.
