**Fluorine Plastic Magnetic Pump Operation and Maintenance Guide**
1. **Startup and Operation**
a. Before starting the pump, make sure the surrounding area is clean and free of debris to avoid any potential hazards. Ensure that safety personnel are aware of the operation.
b. Prior to starting the pump, fill it with the liquid to be transported (especially if the pump is in a suction position). Open the inlet valve, close the outlet gate valve, and then connect the power supply.
c. Turn on the power and check the direction of rotation. If the rotation is incorrect, stop the pump immediately and adjust the wiring.
d. Perform a trial run for 3 to 6 minutes. If no abnormalities occur during this period, the pump can be put into normal operation.
e. After long-term shutdown or maintenance, before starting the pump for the first time, remove the motor fan cover and manually rotate the shaft to ensure smooth movement. Once confirmed, reinstall the fan cover.
2. **Normal Shutdown**
When shutting down the pump normally, close the outlet gate valve first, then turn off the power supply.
3. **Emergency Shutdown**
In case of an emergency, stop the motor immediately, then close both the outlet and inlet valves to prevent backflow and damage.
4. **Maintenance and Care**
a. Regularly inspect the pump and motor, and replace any worn-out parts as needed.
b. If the pump is not in use for an extended period, clean the internal flow channel thoroughly and disconnect the power supply.
c. Never operate the pump without liquid, as this can cause severe damage to the internal components.
5. **Operating Instructions**
a. Monitor the pressure difference across the suction filter. An increasing pressure difference may indicate blockage, so the pump should be stopped and the filter cleaned.
b. Check whether the discharge volume and pressure match the specified values.
c. Listen for any unusual noises or vibrations. Abnormal sounds often indicate cavitation or bearing wear.
d. If cavitation occurs, open the outlet valve gradually. If a sudden noise and vibration occur and the flow does not increase, it is likely due to cavitation. In such cases, perform an exhaust operation immediately. **Note:** The magnetic pump must never operate under cavitation conditions, as this can lead to premature bearing failure.
e. Monitor the motor current to ensure it does not exceed the rated value.
f. Check the temperature of all pump components. Any abnormal heating may signal a problem.
g. Ensure that the nitrogen regulator system pressure remains within the specified range to maintain proper sealing and performance.
Proper operation and regular maintenance are essential for the longevity and efficiency of fluorine plastic magnetic pumps. Always follow the manufacturer’s guidelines and safety protocols.
Refrigeration ball valves, are manually operated shut-off valves suitable for bi-directional flow. Refrigeration ball valves are used in liquid, suction and hot gas lines in refrigeration systems of food retail industry.
