Check whether the pump body bolts, heat exchanger, etc. are in good condition. 2. Shut down the pump, the inlet and outlet drain valves, as well as the manual valve at the pump outlet ； 3. Start the inlet pipe pump line, and vent at the high point ； 4. After pumping is complete, reinstall the pressure gauge and gradually open the inlet manual valve ； 5. Turn on the heat pump circuit ； 6. Start up the auxiliary pump of the lubricating oil station, as well as the seal oil water cooler ； 7. Power supply.
Conduct a thorough inspection, put the circulating water system into operation, start the pumps, and turn on the pre-heating element to carry out slow pre-heating
Apply lubricant, start the circulating water, use a pre-heater to pre-heat the machine, fill the pump, turn the shaft, and activate the sealing system

First, turn on the heating furnace to preheat the oil.
Switch after filling the pump, preheating, and normal standby mode
When restarting the unit after maintenance and preheating it again, it is necessary to strengthen the turning of the shaft
Lubrication, water cooling, thermometer, and pressure gauge are all in operation. Cylinder pump, open outlet, close inlet, rotate pump, preheat, power on
