Pneumatic diaphragm pump installation and use guide
Pneumatic diaphragm pump is a new type of conveying machinery, compressed air as the power source, can handle a variety of corrosive liquids, liquid containing particles, high viscosity liquids, volatile liquids, flammable liquids and highly toxic liquids. As a commonly used equipment in the chemical industry, its installation and use must comply with certain specifications to ensure safety and efficiency. The following is the installation precautions and use points of pneumatic diaphragm pump.
First, installation precautions
1. Location selection
Noise and safety: The installation location should prioritize noise control and safety factors to avoid interference or potential hazards to the working environment.
Space layout: Ensure that the installation area has sufficient space to avoid area blockage caused by concurrent installation, which may affect the installation and operation of other devices.
2. Pipeline layout
Reasonable planning: Before determining the final installation position, the rationality of pipeline layout should be fully considered to avoid affecting the performance of the pump due to pipeline problems.
Simple connection: Inlet and outlet pipes should be as short and straight as possible to reduce unnecessary elbows and fittings to reduce fluid resistance and improve efficiency.
Independent support: Each pipe should be able to support itself to avoid additional stress on the pump body.
3. Installation height
Self-priming capacity: Select the appropriate installation height according to the self-priming capacity of the pump to prevent the self-priming capacity from decreasing due to too high installation, affecting the normal operation of the pump.
4. Air supply
Ventilation pipe installation: Each pneumatic diaphragm pump should be equipped with ventilation pipes to ensure sufficient air supply to meet the needs of the pumping flow.
Air pressure control: The air pressure should not exceed 7 bar, and the specific pressure value should be adjusted according to the actual pumping requirements to avoid damage to the equipment due to excessive air pressure.
5. User friendliness
Easy maintenance: The installation position should be convenient for maintenance personnel to perform routine check and troubleshooting to ensure long-term stable operation of the device.
Vibration reduction measures: Install a vibration reduction pad between the pump body and the base to reduce the vibration of the pump body and extend the life of the equipment.
Second, use precautions
1. Fluid requirements
Particle size: Ensure that the particle diameter in the fluid does not exceed the safe passage standard of the pump to avoid clogging or damaging the pump body.
Fluid properties: Ensure that the conveying fluid will not corrode or damage the pump body and pipeline, and select the appropriate material to extend the service life of the equipment.
2. Perform safe operations
Esd measures: Use an ESD hose and ensure that the grounding resistance is less than 100 ohms. Periodically check the reliability of the grounding system to prevent dangers caused by electrostatic sparks.
Exhaust direction: The exhaust port shall not directly face the personnel or working area to avoid injury caused by material ejection due to diaphragm rupture.
3. Pressure control
Working pressure: Do not exceed the maximum allowable working pressure of the pump, too high air pressure may cause equipment damage or personal injury.
Decompression maintenance: Before maintaining the pump, cut off the air intake and open the bypass pressure release mechanism to ensure that the pipeline system is completely decompressed before operating.
4. Environmental requirements
Ventilation and exhaust: Keep the installation area well ventilated, avoid heat sources and flammable and explosive materials, and ensure a safe working environment.
Discharge treatment: Discharge of flammable or toxic liquids should be connected to a safe area away from the workplace.
5. Operation specifications
Training and guidance: Ensure that all operators are familiar with the safe operation process of the pump and related preventive measures to avoid accidents caused by improper operation.
Avoid idling: Do not idle the pump for a long time, so as not to damage the equipment.
Third, maintenance and maintenance
1. Check regularly
Regularly check the pump body, piping and connecting parts status, timely replacement of worn or damaged parts.
Check the cleanliness and operating status of the air circuit system to ensure that it is working properly.
2. Troubleshoot the fault
If it is found that the pump body vibration is abnormal or the flow rate is reduced, it should be stopped immediately for inspection, and then resume operation after troubleshooting.
By following the above installation and use specifications, the operational efficiency and service life of pneumatic diaphragm pumps can be significantly improved, while ensuring operator safety.
