Centrifugal pump installation instructions 1. After installation, toggle the pump shaft, the impeller should be no friction or stuck, the pump should be disassembled to check the reason.
2. The pump is divided into two types: rigid connection and flexible installation (see connection mode).
3.Before installation, check whether the fasteners of the unit are loose or not, and whether there is any foreign matter in the flow passage of the pump body to avoid damaging the impeller and the pump body when the pump is running.
4. The weight of the pipeline should not be added to the pump during installation so as not to deform the pump.
5. The anchor bolt must be tightened during installation to avoid the effect of vibration on the performance of the pump when starting.
6. In order to facilitate maintenance and use safety, install a regulating valve on the inlet pipe of the pump and a pressure gauge near the pump outlet to ensure operation within the rated head and flow range to ensure the normal operation of the pump. The service life.
Piping centrifugal pump start and stop
Preparation before starting:
1. Test motor rotation is correct, from the top of the motor to the pump as a clockwise rotation, the test time should be short, so as to avoid mechanical seal dry wear.
2. Open the exhaust valve so that the liquid fills the entire pump body and close the exhaust valve when it is full.
3. Check if all parts are normal.
4. Turn the pump by hand to allow the lubricating fluid to enter the mechanical seal face.
5. The high-temperature type should be preheated first, and the heating rate is 50°C/hour to ensure that the various parts are evenly heated.
start:
1. Fully open the inlet valve.
2. Close the spout valve.
3. Start the motor and observe if the pump is operating correctly.
4. Adjust the opening of the outlet valve to the required working conditions. If the user has a flow meter or pressure gauge at the outlet of the pump, the pump should be operated at the rated point listed in the performance parameter table by adjusting the opening of the outlet valve. At the outlet of the pump equipped with a flow meter or pressure gauge, the outlet of the outlet valve should be adjusted to measure the motor current of the pump so that the motor can operate within the rated current, otherwise the pump will be overloaded (ie, high current operation) to make the motor Burnout. Adjusting the opening of the outlet valve is related to the condition of the pipeline.
5. Check the shaft seal leakage, normal mechanical seal leakage should be less than 3 drops / min.
6. Check the motor, bearing temperature rise 70 °C.
parking:
1. High-temperature type first cooling, cooling rate <10 °C / min, the temperature dropped to below 80 °C, before parking.
1. Close the spout valve.
2. Stop the motor.
3. Close the inlet valve.
4. If the vehicle is stopped for a long time, the pump should be drained.
