The undisturbed operation of hydraulic machines and devices in the industry has a significant impact on the performance of each individual company. If defects occur, it is very important to repair them as quickly as possible. In the production of the cardboard there was a breakdown of the vane pump with a variable displacement. Our task is to renovate the pump and determine if we have improved it.
The diploma task is to learn about the operation and components of the pump. Before the renovation we measured the working pressures and flows and determined the volumetric efficiency, which was equal to 53%. Through the identification of the worn components, we were able to determine the instructions for renewal and to carry out the renovation. After the renovation, we measured the working pressure at the two possible levels of adjustment. We also carried out measurements of the flow through which we determined the volumetric efficiency of the renovated pump.
