The starting method of the centrifugal pump is mainly manual start and automatic start, and different starting methods can be selected under different circumstances. During the operation, pay attention to safety and ensure the normal operation of the equipment to achieve the best energy-saving effect and use effect.

Method of 1. automatic start of centrifugal pump

Automatic start centrifugal pump needs to cooperate with the control system, the specific steps are as follows:

1. Configure the control system: install the control system, connect all sensors, instruments and other equipment to the control system, and configure the parameters and control logic correctly.

2. Import parameters: import the parameters and working status of the centrifugal pump into the control system, and set the enabling conditions and thresholds.

3. Start the control system: connect the control system to the power supply and start the system.

4. Automatic control: When the control system monitors the need to run the centrifugal pump, it will automatically start the centrifugal pump, and automatically control and adjust after starting to ensure the stability and safety of fluid delivery.

View before starting the 2. centrifugal pump

① After the motor is repaired, check whether the rolling direction of the motor is accurate before connecting the coupling.

② Check whether the pump inlet pipeline and auxiliary pipeline, flange and valve device meet the requirements, whether the anchor bolt and ground wire are outstanding, and whether the coupling is installed.

③ Check whether the turning is normal or not.

④ Check whether the oil level of smooth oil is normal, add oil without oil, and check the oil quality of smooth oil (grease).

⑤ Open each cooling water valve and check whether the pipeline is dredged. Pay attention to the cooling water should not be too large or too small, too large will cause waste, too small cooling effect is poor. Usually the cooling water flow can be linear.

⑥ Open the inlet valve of the pump, close the outlet valve of the pump, and open the hand valve of the pressure gauge.

⑦ Check the sealing condition of the pump and the opening of the oil seal.

3. method of manually starting centrifugal pump

The method of manually starting the centrifugal pump is relatively simple, just follow the following steps:

1. Preparation: Check the status of the centrifugal pump, pipelines and valves to confirm that they are all closed; check whether the wiring of the motor is correct.

2. Turn on the power supply: turn on the centrifugal pump and turn on the main power switch.

3. Open the valve: slowly open the valve on the inlet and outlet pipelines, and let the liquid slowly enter the centrifugal pump until the liquid level flows out stably.

4. Start the motor: press the start button to start the centrifugal pump motor, pay attention to the change of the tachometer, and ensure that the pump speed is in the normal range.

5. Close the valve: Wait until the speed is stable, slowly close the valves on the inlet and outlet pipelines until they are all closed.

The starting process of the centrifugal pump needs to go through the above steps, and each step must be strictly operated to ensure the normal operation of the pump. At the same time, the operator also needs to know some basic safety knowledge to ensure the safety of the work.
