Safety Operating Procedures for Screw Air Compressors

I. Pre-Startup Safety Inspection

Before starting the equipment, operators must conduct a thorough inspection to ensure that the equipment is in a safe and ready-to-operate condition.

• Check that the lubricant level is within the normal range and that the oil is clean.
• Check that the cooling system is functioning properly, and verify that all connecting pipelines are secure and free of leaks.
• Check that the power supply voltage is stable and that the grounding wire is securely connected.
• Clear away any debris around the equipment to ensure unobstructed operating space.

II. Startup and Operational Monitoring

Start the equipment strictly in accordance with the control panel instructions, and maintain close supervision throughout operation.

• After startup, listen for the equipment’s operating sounds and verify that there are no abnormal vibrations or unusual noises.
• Observe the instrument panel, monitor exhaust pressure, exhaust temperature, and motor current, and ensure that all parameters remain within their rated ranges.
• Strictly prohibitedRemove piping, valves, or protective guards while the equipment is in operation.
• Ensure adequate ventilation in the equipment room, and maintain an ambient temperature that meets the equipment’s operating requirements.

III. Standardized Shutdown Procedures

Shutdown procedures must follow standard protocols to prevent equipment damage caused by abrupt stops.

• During normal shutdown, first press the stop button, and after the equipment has run unloaded for a period of time, disconnect the main power supply.
• In the event of an emergency, press the emergency stop button; however, the cause must be identified and the system reset before it can be restarted.
• After shutdown, close the cooling water inlet valve and drain the condensate from the system.

IV. Routine Maintenance and Precautions

Proper daily maintenance is the foundation for ensuring the long-term safe operation of equipment.

• Regularly replace the lubricating oil, oil filter, and air filter.
• Regularly verify the functionality of safety valves, pressure sensors, and other safety protection devices.
• Non-professional maintenance personnelStrictly prohibitedUnauthorized adjustment of internal device parameters or disassembly of core components.
• Establish equipment operation and maintenance records, documenting the details of each routine service and repair.

V. Emergency Response Measures

In the event of an emergency, operators should remain calm and take appropriate measures.

• If the equipment suddenly triggers high-temperature or high-pressure alarms, or experiences severe gas or oil leaks during operation, immediately press the emergency stop button and disconnect the power supply.
• In the event of an electrical fault or fire, first disconnect the main power supply and use a dry‑powder or carbon‑dioxide fire extinguisher to extinguish the blaze.Strictly prohibitedExtinguish with water.
• Report equipment malfunctions promptly, and have them inspected and repaired by qualified personnel.
