OPPAIR PM VSD Screw air compressors, as efficient and reliable air compression equipment, are widely used in various fields of industrial production. To meet specific production requirements, proper adjustment of rotary air compressor parameters is essential. This article will detail how to adjust PM VSD screw air compressor user parameters to help you better operate and maintain your compressor.
I. Basic Principles of Screw Air Compressors
A screw compressor primarily consists of a pair of parallel, inter meshing male and female rotors. The male rotor is the active rotor, and the female rotor is the passive rotor. Driven by an electric motor, the male rotor rotates the female rotor, completing the air intake and compression process. This structure offers the advantages of high efficiency, excellent reliability, and the ability to provide stable air pressure.
II. The Importance of User Parameter Adjustment
The user parameters of a screw compressor primarily include air pressure, air flow, and motor speed. Adjusting these parameters directly affects the performance and effectiveness of the compressor. Proper parameter adjustment can improve compressor efficiency, reduce energy consumption, and extend equipment life. Therefore, mastering the correct parameter adjustment method is crucial for users.
III. Parameter Adjustment Methods for Screw Air Compressors
Parameter adjustment for screw air compressors depends on the specific equipment model and usage. Generally, the following steps are required:
1. First, inspect the air compressor. Check that the three pressures are normal: inlet pressure, outlet pressure, and exhaust pressure. Check that the oil level is within the standard range.
2. After confirming that the machine is operating normally, first set and debug the control box parameters. Determine the pressure set point based on actual air usage and enter it into the control box.
3. Adjust the machine's rated pressure. The general adjustment method is to first reduce the pressure to the set value (usually set between 7.5 and 8 bar), then gradually increase the pressure to observe the machine's operating conditions.
4. Adjust the machine's exhaust temperature: If the exhaust is overheating, you can lower the exhaust temperature by adjusting parameters such as the machine's inlet air temperature, the cooling water flow rate of the water cooler, and the cooling water flow rate of the oil cooler.
IV. Parameter Adjustment Precautions
- Before adjusting parameters, be sure to understand the equipment's performance characteristics and operating specifications to ensure the safety and effectiveness of the adjustment process.
- During adjustments, closely monitor the equipment's operating status and changes in various parameters, and promptly address any problems.
- After adjustments are completed, observe and test the equipment for a period of time to ensure that the parameter adjustments have achieved the intended results.
- Perform regular maintenance and servicing on the equipment to ensure its normal operation and service life.
- If any equipment malfunction or abnormality occurs, immediately shut it down for inspection to avoid further damage.
- During operation and maintenance, pay attention to environmental hygiene and keep the workplace clean and safe.
- Comply with relevant laws, regulations, and standards to ensure that the equipment's safety and environmental performance meet requirements.
8. Adjustments to key equipment and important parameters are recommended to be performed by professional technicians to ensure safety and stability.
V.Screw air compressors are common industrial equipment.
The following points should be observed during operation:
1. Do not store flammable or explosive items near the equipment. Also, ensure that the air intake is not blocked during operation.
2. Pipelines are pressurized; do not loosen pipe plugs or valves, such as steam traps and drains.
3. Regularly check lubricant oil usage. If the oil level is low and gradually rising, shut down the machine. Refill lubricant when the machine is pressure-free.
4. Regularly check the screw air compressor's automatic steam trap for proper operation to prevent moisture from entering the system.
5. Drain the oil and gas tanks weekly. The unit must be running for at least 2 hours per week.
6. During routine operating checks, ensure the pressure switch and interlocking control program are functioning properly. Abnormal machine operation increases energy consumption and, in severe cases, can cause motor burnout.
7. If unusual noises or vibrations occur during operation, shut down the machine immediately for inspection.
8. The operating pressure of the air compressor must be consistent with the pressure indicated on the nameplate to ensure efficient operation and minimize energy consumption.
