The individual steps for repairing driven machines such as pumps are: removal and installation of pumps for inspection, repair or replacement; aligning the drive and commissioning and checking the pump, e.g. For leaks. In conjunction with the tank system, the connecting pipes and one of the four pumps, the assembly stand forms a complete training system for complex piping and plant systems. The training system forms a closed water circuit.
Learning Objectives And Experiments
