Stainless steel horizontal centrifugal pump instructions and installation
Stainless steel centrifugal pump instructions and installation:
1. Test whether the motor is turning correctly. See the clockwise rotation from the top of the motor to the pump. The test time should be short to avoid dry wear of the mechanical seal.
2. Open the exhaust valve to fill the entire pump body and close the exhaust valve when it is full.
3. Check if all parts are normal.
4. Rotate the pump by hand to allow the lubricating fluid to enter the mechanical seal end face.
5. The high temperature type should be preheated first, and the heating rate is 50 °C/hour to ensure uniform heating of all parts.

Start:
1. Fully open the inlet valves.
2. Close the outlet valves.
3. Start the motor and observe if the pump is running correctly.
4. Adjust the opening degree of the outlet valve to the required working conditions. If the user installs a flow meter or pressure gauge at the pump outlet, the pump should be operated at the rated point listed in the performance parameter table by adjusting the opening degree of the outlet valve. If the user installs a flow meter or pressure gauge at the pump outlet. The motor's current should be measured by adjusting the outlet of the outlet valve to make the motor run within the rated current. Otherwise, the pump will be overloaded (ie, operated at high current) to make the motor burned out. Adjusted suitable outlet valve opening is important.
5. Check the leakage of the shaft seal. The leakage of the mechanical seal should be less than 3 drops/min.
6. Check if the temperature rise of the motor and bearing at ≤70°C.

Parking:
1. The high temperature type cools down at first, the cooling speed is <10 °C/min, and the temperature is lowered to below 80 °C, then park.
2. Close the outlet valves.
3. Stop the motor.
4. Close the inlet valves.
5. If the vehicle is parked for a long time, the liquid in the pump should be drained.
