What preparations should be made before starting the pump, and what should be paid attention to after it starts running and during normal operation? Answer: Before starting the pump, the following preparations should be made: ① Conduct a thorough inspection of the pump. ②Fill the bearing housing with oil or activate the lubrication system. ③Turn the crank. ④Open the inlet valve to vent the system. ⑤Contact an electrician to test the motor’s insulation and restore power. ⑥Make sure to fully close the outlet valve before starting the pump. The following points should be noted after starting the pump and during normal operation: ① Check whether the pressure at the pump’s inlet and outlet is normal. ②Check whether the oil level in the bearing housing or the lubricating oil tank is normal. ③Monitor whether the bearing temperature and the motor stator temperature are within normal ranges, and during inspections touch the bearing housing with your hand to feel if it is hot. ④Monitor whether the vibration is normal and check whether the sound is normal. ⑤Check for leaks in the mechanical seal.
