Attentions for the Use of Resin reactor kettle Booster Gear Pump

The following are the attentions that need to be paid when using a resin reactor kettle booster gear pump:

I. Preparation Before Startup

Check the Process Flow: Ensure that the process flow is correct to avoid equipment damage or safety accidents due to misoperation.

Clear Obstacles: Check if there are any obstacles around the gear pump that may hinder its operation, and ensure there is sufficient space around the equipment for safe operation.

Tighten Bolts: Check if the bolts of the coupling protective cover and the foundation feet are tightened to prevent vibration or noise due to loosening during equipment operation.

Check Lubricating Oil: Ensure that there is sufficient lubricating oil in the bearing housing, and the oil level is maintained within the specified range to ensure the lubrication and cooling effect of the equipment.

Select and Fit Pressure Gauge: Select and fit an appropriate pressure gauge according to the purpose and working nature of the gear pump to monitor the operating pressure of the equipment.

Check Voltage: Ensure that the voltage is within the specified range, and the motor wiring and electrostatic grounding are normal to avoid equipment damage or safety accidents due to electrical faults.

II. Startup Operation

Open Inlet Valve: Before starting the gear pump, open its inlet valve to ensure that liquid can enter the pump smoothly.

Vent Gas: Open the vent valve of the gear pump, vent the gas inside the pump, and then close the vent valve to avoid affecting the normal operation of the pump.

Open Outlet Valve: After confirming that there is no gas inside the pump, open the outlet valve of the gear pump and prepare to start the motor.

Start Motor: Start the motor, observe if the gear pump is running in the correct direction, and check for any abnormal sounds or vibrations. If there are any abnormalities, immediately stop the pump, inspect, and troubleshoot.

III. Operation Monitoring

Stable Pressure Indication: During the operation of the gear pump, ensure that the pressure indication is stable and the pressure fluctuation is within the specified range.

Listen to Equipment Sounds: Listen to the sounds inside the gear pump casing and the bearings to ensure there are no abnormal sounds or vibrations. If there are any abnormalities, immediately stop the pump for inspection.

Check Motor Current: Ensure that the motor current is within the specified range on the nameplate to avoid equipment damage due to motor overload.

Check Shaft Seal Leakage: Regularly check the leakage of the shaft seal. Normally, the leakage of the stuffing seal should be controlled within a certain range (e.g., 10~20 drops/minute) and there should be no heating phenomenon. The leakage of the mechanical seal should be less than the specified value.

Record Operating Data: Record the operating data of the gear pump on time, such as pressure, flow rate, temperature, etc., to detect abnormalities in a timely manner and take appropriate measures.

IV. Shutdown Operation

Cut Off Power Supply: Before shutting down, cut off the power supply to stop the motor to avoid equipment damage or safety accidents due to continued motor operation.

Close Outlet Valve: Gradually close the outlet valve of the gear pump to avoid a sudden interruption of liquid, which may cause a sudden increase in pressure inside the pump.

Close Inlet Valve: After the gear pump stops operating, close its inlet valve to prevent liquid backflow or leakage.

V. Maintenance and Servicing

Regular Lubrication: Frequently check and add lubricating grease to ensure good lubrication of the bearings. The lubricating grease should be replaced regularly to avoid using expired or substandard oil products.

Inspection and Repair: Regularly check the power cord, internal wiring, plugs, switches, and other components of the gear oil pump to ensure they are in good condition and the insulation resistance is normal. If there are any damages or abnormalities, replace or repair them in a timely manner.

Store Parts: When dismantling and inspecting the gear oil pump, store each part properly, especially the explosion-proof surface of the explosion-proof parts, which should not be damaged. If there is any damage, replace it with a new identical part.

Replace Seals: Regularly check the seals and replace them in a timely manner if severe wear is found to prevent leakage from affecting the normal operation of the equipment.

VI. Safety Precautions

Professional Training: Operators should receive professional training to be familiar with the working principle, operating procedures, and safety precautions of the gear pump.

Do Not Touch Rotating Parts: During pump operation, it is strictly prohibited to touch rotating parts to avoid mechanical injury.

Handle Abnormalities: If abnormal sounds, vibrations, or leakage are found, immediately stop the pump for inspection and troubleshooting. It is strictly prohibited to operate forcibly, which may cause equipment damage or safety accidents.

Comply with Electrical Safety Regulations: During maintenance and operation, comply with electrical safety regulations to prevent electric shock accidents. If electrical maintenance is required, it should be handled by a professional electrician.

In summary, when using a resin reactor kettle booster gear pump, attention needs to be paid to various aspects, including preparation before startup, startup operation, operation monitoring, shutdown operation, maintenance and servicing, and safety precautions. Only by strictly following these precautions can the stable operation and long lifespan of the equipment be ensured.
