Pump running of water pump project debug

J&T pump running of water pump project debugging by J&T pump manufacturers ( www。 gdhzsb。 com） Main responsible for 1) commissioning before the note a. Water pump in the anhydrous state motor cannot point to check and reversing. b。 Rinse carefully before pump commissioning the line, guarantee not into foreign body in the water pump, the water pump must be filled with water before starting to boot for the first time. c。 After the pump installed, inform the factory to inspect, debug before did not run on its own, must to run after by factory personnel to be present. d。 The import and export of water pump must be installed pressure gauge, in the case of no pressure gauge for debugging. e. The pump must be hydropower in place before need to debug. 2) Check a water pump. Record and check the water pump and motor nameplate data; b。 Check for the return pipe, valves, pressure gauge, telescopic tube, check valve, such as whether the installation is complete, and meets the requirements; c。 Check whether the water pump and motor drive feeder is complete and meets the requirements; d。 Check the pump shaft seal for leaks; e. Turn the pump shaft by hand to measure whether the operation is flexible; f。 Power supply system correctly and water pump control cabinet has been access to the formal power, g. The water pump to cable between control cabinet is connected correctly. h。 To check whether there is sundry, water water pump vibration reduction set bottom suspension complete facilities whether effective. 我。 Into the water before and after into the water to test the bearing. j。 System of water is enough, and the water pump has been fully filled pump (3) Water pump commissioning a. Water pump and motor bearing oiling; b。 Correction of water pump and motor drive feeder machine, manual turning; c。 Set the pump valve in open position appropriate pipeline system; d。 System of water is enough, check and make sure the pump pipeline system has been filled with water, and has set up a discharge air; e. To determine the pump water supply pipeline valve in seated position; f。 Test the launcher, and correction of overload protection set point; g。 Start the pump motor, check the water pump to correct, record start and running load current, voltage and speed; h。 Slowly open pump water supply pipeline valve to design pump head/pressure differential, and record the load current, voltage, and measure speed, measure and record the water pump top technical parameters, and compared with the working characteristic curve. 我。 Water pump, the motor vibration and noise test conformed to the specification requirements. j。 Testing the function of building automation linkage contact; k。 Working load test run not less than two hours. l Water during commissioning, control the current of the motor can't more than ratings, and water flow cannot be less than 20% of the rating; m。 Flow pump operation, the bearing shell of the highest temperature should not exceed 75 & ordm; C; Sliding bearing is not more than 70 & ordm; Ｃ。
