Single-screw air compressor operating procedure video

Video Content Overview

This video provides a detailed demonstration of the standardized operating procedures for single-screw air compressors. Through clear on-site operations and voice narration, it helps operators quickly master equipment start-up and shutdown protocols, key points for operational monitoring, and routine maintenance techniques, ensuring production safety and optimized energy efficiency.

Pre-Startup Inspection and Preparation

The following safety checks must be completed before starting the equipment:

• Environment and Basics:Confirm that the equipment room is well-ventilated, the temperature meets equipment requirements, and the floor is level with no standing water.
• Lubrication System:Check that the oil level is within the range specified on the sight glass and that the oil is free of emulsification or contaminants.
• Pipeline Connection:Verify that the intake valve is closed, the exhaust shut-off valve is slightly open, and the electrical wiring connections are secure and undamaged.
• Dashboard Status:The voltmeter and pressure gauge pointers have returned to zero, and no alarm codes are displayed on the control cabinet.

Standard Startup Procedure

Perform the startup procedure in accordance with regulations to avoid impact loads:

• Power-on preheating:Close the main power switch; after the control system completes its self-test, it enters standby mode.
• Start Host:Press the start button; the motor drives the screw rotor to rotate at low speed, establishing initial oil pressure.
• Load and Run:Once the oil pressure reaches the set value, the intake valve opens automatically, and the compressor gradually loads to its rated operating condition.
• Parameter verification:Observe whether the exhaust pressure, exhaust temperature, and current values remain stable within their normal ranges.

Key Monitoring Points During Operation

During operation, dedicated personnel must conduct regular inspections, with particular attention to the following parameters:

• Temperature Monitoring:Exhaust gas temperature should generally not exceed the design limit, and lubricating oil temperature must be maintained within a reasonable operating range.
• Abnormal sounds:Listen for any metallic rubbing or loud vibration noises inside the host casing; if you detect any unusual sounds, stop the machine immediately and perform a diagnostic check.
• Leak Check:Regularly inspect all flange connections, oil pipe joints, and the cooler surface for signs of air or oil leakage.
• Filter cartridge status:Monitor the air filter differential pressure indicator and replace the filter promptly when it becomes clogged to prevent increased energy consumption.

Standardize the shutdown process

The correct shutdown procedure can extend the life of the host and prevent condensate backflow:

• Uninstall Pending:First, switch the equipment to the卸载 state, cut off the gas supply load, and let the main unit run idle for several minutes.
• Stop Host:Press the stop button to de-energize the motor; the control system then continues to run the cooling fan for a preset duration.
• Pressure relief and drainage:After the unit has come to a complete stop and the system pressure has dropped to zero, open the drain valve at the bottom of the air receiver tank to discharge the condensate.
• Power outage evacuation:Turn off the main power switch, clear away debris in the surrounding area, and complete the operation log.

Safety and Maintenance Recommendations

The single-screw design offers high load capacity and low vibration, but routine maintenance must still strictly follow the manual’s recommendations. It is advised to replace the oil filter and oil–gas separator element after a specified operating time, and to calibrate sensor accuracy regularly. Operators must undergo professional training before taking up their duties; unauthorized modification of control parameters or bypassing safety devices is strictly prohibited. Adhering to standardized procedures not only reduces failure rates but also significantly improves air quality and overall system efficiency.
