① Before starting, the pump must be filled with clean hydraulic oil through the oil return port on the pump casing, otherwise it is not allowed to start.
②Turn the coupling by hand to check whether the force of the pump shaft is uniform during rotation (you can find whether there is a problem with the pump assembly), and check whether the two couplings are concentric and whether there is a necessary axial gap between the two couplings .
③ Check whether the rotation direction of the motor is consistent with the specified rotation direction, and whether the oil inlet and outlet are installed correctly.
④ There should be an empty-load circulation circuit in the hydraulic system, so as not to start and stop the pump with full load (it is easy to reduce the service life of the pump and cause the prime mover to overload). The adjustment pressure of the safety valve in the hydraulic system shall not exceed 35MPa.
⑤ When the pump is started, it will be started first.
