Installation Precautions for screw type compressor

When installing screw type compressor, it’s crucial to adhere to a set of guidelines to ensure optimal performance, safety, and longevity of the equipment. Here are the key considerations for a seamless installation process:

1. Foundation and Location: The screw type compressor must be placed on a flat, solid surface, avoiding soft soil or unstable ground. This ensures stability during operation and prevents vibrations that could damage the machine.

2. Electrical Configuration: Select the appropriate power cable size and verify the voltage’s accuracy. Incorporate necessary safety devices such as air switches and fuses into the power supply line. Comply with electrical installation regulations by connecting a suitable grounding wire and leaving ample maintenance space around the machine.

3. Piping Configuration: Ensure the main pipeline has a 10-20-degree downward slope to facilitate condensate drainage and prevent moisture accumulation.

4. Motor Rotation Check: Before first startup or any change in power supply, verify the motor’s rotation direction to prevent oil starvation and potential damage to the screw type compressor head.

5. Operational Safety: Never loosen, disconnect, or tamper with piping components, fittings, or devices while the compressor is running. High-pressure, high-temperature fluids within the system can cause severe injuries.

6. Maintenance and Repair Precautions:

   • Stop the compressor before performing any maintenance (e.g., oiling) or repairs.
   • Cut off power to ensure the compressor is fully de-energized.
   • Confirm that the compressor system is depressurized before proceeding.

7. Operational Pressure Limits: Never operate the compressor above the maximum discharge pressure specified on its nameplate to prevent damage.

8. Safety Valve Monitoring: The safety valve, installed on the oil-air separator, releases excess pressure if it exceeds the set limit. Immediately investigate the cause of overpressure whenever the safety valve activates.

9. Lubricant Selection: Use only the screw air compressor-specific oil recommended by the manufacturer. Avoid mixing different brands of lubricant as it can compromise the compressor’s performance.

10. Regular Inspections: Routinely inspect critical components such as the motor, temperature sensors, pressure transmitters, control panel, wiring, and oil-air separator filters. Neglecting these inspections could lead to fire hazards.

11. Professional Assembly: The compressor’s main assembly requires specialized skills. Users must refrain from disassembling the compressor’s core components without the assistance of highly trained technicians.

By following these comprehensive installation precautions, you can maximize the efficiency, reliability, and safety of your screw air compressor, ensuring a smooth and trouble-free operation for years to come.
