ã€For the operator's safety, DG horizontal multi-stage boiler feed pump must be operated in accordance with the nameplate requirements, so as not to endanger the safety of equipment and operator. Then in the operation of DG horizontal multi-stage boiler feed pump, which operating procedures to follow it? Then we introduce DG horizontal multi-stage boiler feed pump operating procedures. DG horizontal multi-stage boiler feed pump operation (A) Start: 1, the pump should be operated before the first rotor, check the rotor is flexible. 2, check the motor steering is consistent with the pump steering. 3, close the pump outlet gate valve, pressure gauge cock, with the delivery of liquid or vacuum system to exclude the suction tube and the body of the air pump (no empty car start running). 4, check the pump and motor coupling bolt tightness and safety around the pump, so that the pump is ready to start. WARNING: EQUIPMENT OPERATES ONLY FOLLOWING THE COUPLING SHIELD AND MISCELLANCE OF THE SAME CAUSED BY PERSONAL INJURY. 5, start the pump, to be normal operation of the pump, open the pressure gauge cock, slowly open the outlet gate valve, press the outlet pressure gauge to control the pump given head. (B) operation: 1, the type of pump balance within the axial force balance mechanism, the balance device has a balanced liquid outflow, the balance of water from the balanced water pipe connected to the suction section. 2, this type of pump bearing all have cooling devices, pumps must be connected before the cooling water pipe. Bearing temperature changes reflect the assembly quality of the pump, the bearing temperature shall not exceed 35 ℃ ambient temperature, the maximum temperature should not exceed 75 ℃. WARNING: Handling equipment that is not properly lubricated may cause bearing heat, rupture, pump stalls, equipment damage, and personal injury to the operator. 3, the pump rotor in operation there is a certain degree of axial swimming, the motor and the pump should ensure that the gap between the two coupling end face value. 4, the pump should be checked during operation impeller, seal ring, guide vane sets, balance disc, sleeve wear, excessive wear should be promptly replaced. 5, the user should be based on the specific circumstances set out a more detailed operating procedures. (C) Parking: stop the pressure gauge cock before closing, and then slowly close the exit gate valve until the exit gate valve is closed to stop the motor.
