Caution Required for ScrewAir Compressor Use in Winter: Experts Remind Users to Take Precautions Against Freezing and Ensure Production Safety
Reported by this newspaper: Recently, with temperatures plummeting in many parts of the country, screw air compressor widely used in industrial production are facing challenges due to low temperatures. Reporters learned from several equipment maintenance companies and industry experts that low winter temperatures can easily lead to problems such as difficulty starting air compressors, lubrication failure, and pipe freezing and cracking, and in severe cases, even equipment shutdowns or safety accidents. Therefore, experts urge companies to strengthen the maintenance and management of air compressors in winter, strictly implement antifreezing measures, and ensure safe and stable production operation.
Low Temperature Hazards: Air Compressors' "Fear of Cold" Causes Multiple Risks
As a key piece of equipment in the industrial field, the operational stability of air compressors directly affects production efficiency. However, the low winter environment can significantly affect its core components and operating parameters:
Lubrication System Failure: Low temperatures increase the viscosity of lubricating oil and reduce its fluidity, which may cause insufficient lubrication of the compressor head, exacerbating wear and even causing seizure.
Condensation Freezing: Water vapor in compressed air easily condenses into water at low temperatures. If not discharged in time, it may block pipes or freeze and crack the air tank.
Frequent electrical faults: Problems such as brittle cables and oxidized contactor contacts are more likely to occur at low temperatures, increasing the risk of electrical fires.
Difficulty starting: Contraction of internal metal parts and hardening of seals can increase starting resistance, or even prevent normal starting.
A manager of a chemical company revealed to reporters that last winter, due to failure to drain coolant in time, the radiator of an air compressor froze and cracked, resulting in direct economic losses exceeding 100,000 yuan. "Slight negligence in winter maintenance can lead to disaster," the manager stated.
Expert advice: Five measures to strengthen safety defenses
Addressing the pain points of screw air compressor use in winter, the following suggestions are offered:
1. Thorough preheating before starting: Use an electric heater or hot air circulation system to preheat key components such as the compressor head, oil lines, and air lines for 10-30 minutes, ensuring the oil temperature is ≥20℃. Use low-temperature special lubricating oil to avoid starting difficulties due to excessive viscosity.
2. Strengthen the cooling system: Replace the antifreeze coolant and check if the freezing point is lower than the local minimum temperature. Drain accumulated water from the cooling system after shutdown to prevent radiators or pipes from freezing and cracking.
3. Strictly monitor operating parameters. Monitor parameters such as oil temperature, exhaust temperature, and pressure in real time through instruments or intelligent control systems. If any abnormalities are detected, immediately shut down the machine for inspection. Avoid frequent start-ups and shutdowns to reduce equipment wear.
4. Regularly drain condensate. Install high-efficiency air compressor air dryer to lower the dew point of compressed air. Drain condensate from the air tank and filters daily to prevent freezing and blockage.
5. Thoroughly maintain the system after shutdown. Close the intake valve and purge compressed air and residual liquid. Clean snow from the equipment surface and check seals and pipes for aging and cracking.
Safety Warnings: Don't neglect slip and fire prevention.
In addition to equipment maintenance, experts remind companies to strengthen on-site safety management:
Slip prevention: Promptly clear snow around equipment; operators should wear non-slip shoes to avoid falls.
Fire prevention: Do not store flammable materials near equipment; regularly inspect electrical wiring and provide fire extinguishers.
Winter is a high-risk period for inverter screw air compressor failures. Enterprises must adhere to the principle of "prevention first, maintenance foremost," and strengthen safety measures through scientific management and professional maintenance. Industry experts urge enterprises to establish comprehensive winter equipment maintenance systems and regularly train operators to reduce risks at the source and ensure stable production operations.
