Frequent high-temperature alarms in air compressors during winter? Huitong Xinda accurately solves the problems of low-temperature operation

I. Core Operational Pain Points of Air Compressors in Winter

1.Difficulties in starting and frequent tripping: In low-temperature environments, the viscosity of air compressor lubricating oil increases significantly, resulting in poor fluidity and increased motor starting resistance. This easily leads to startup failures or circuit breaker tripping, especially in older equipment.

2.Frequent high-temperature alarms: Insufficient fluidity of lubricating oil reduces heat dissipation efficiency, while the pressure difference of the oil-gas separator increases, preventing timely heat discharge. The operating temperature of the equipment quickly rises to the alarm threshold (usually ≥110°C), forcing shutdowns.

3.Soaring oil consumption and increased costs: Low temperatures impair the atomization effect of lubricating oil. Some inadequately atomized oil is discharged with compressed air, leading to over 30% higher oil consumption compared to normal temperature conditions, along with air source contamination.

4.Degraded air source quality + risk of pipeline freezing and cracking: High air humidity causes compressed air to easily condense into ice in air storage tanks in low temperatures. Failure to drain water promptly not only clogs the tank's drain outlet and affects supply stability but may also cause freezing expansion, leading to tank or pipeline cracks and safety hazards.

5.Aggravated component wear: Reduced lubricating performance of oil at low temperatures increases friction among internal components like bearings and rotors. Long-term operation can cause excessive wear, shortening equipment lifespan.

II. In-depth Analysis of Root Causes

1.Inadequate adaptation of lubricating oil performance: Failure to use winter-specific lubricating oil. Ordinary oil has a high pour point, easily solidifying or increasing viscosity sharply at low temperatures, failing to form an effective oil film, thus affecting lubrication and heat transfer.

2.Missing or irregular preheating procedures: Most enterprises run equipment at full load immediately upon startup in winter without sufficient preheating, causing uneven stress during "cold starts" of components and preventing oil from reaching operating temperature quickly.

3.Contaminated or faulty heat dissipation systems: Dust and oil deposits on radiators and coolers after summer heat are not cleaned timely, further reducing winter heat dissipation efficiency. Some equipment has faulty cooling fans or thermostatic valves, unable to adjust automatically based on temperature.

4.Negligent drainage operations: Lack of a regular winter drainage system leads to accumulated condensed water in air storage tanks, which freezes at low temperatures, triggering safety and operational issues.

5.Inadequate environmental and pipeline protection: Air compressors installed in uninsulated workshops or outdoors are directly affected by low temperatures. Uninsulated compressed air pipelines allow moisture condensation into ice, increasing risks of blockages and cracks.

III. Huitong Xinda Customized Solutions

Addressing winter air compressor operational pain points, Huitong Xinda, combining product features and industry practices, offers a dual "prevention + treatment" solution, ensuring stable winter operation through equipment selection, operational standards, and maintenance:

1.Use No. 46 winter-specific lubricating oil: Recommended for air compressors, it has a pour point ≤-20°C, strong low-temperature fluidity, quickly forming a uniform oil film. It balances lubrication and heat dissipation, effectively reducing motor starting resistance and component wear. For permanent magnet variable frequency models, matching with No. 46 customized oil further enhances energy efficiency and cold resistance, avoiding high-temperature alarms due to oil viscosity issues.

2.Standardize startup and preheating procedures: Check oil level and viscosity before startup. If viscosity is high, run the equipment idly for 5-10 minutes until oil temperature exceeds 40°C before gradual loading. Avoid frequent starts/stops to reduce "cold shock" damage.

3.Strengthen regular drainage of air storage tanks: Establish a special winter drainage system. It is recommended to manually drain water three times daily (morning, noon, evening), each time for at least 30 seconds, ensuring complete removal of condensed water. For automated equipment, check drain valve functionality; replace with anti-freeze valves if necessary to prevent frozen blockages.

4.Optimize heat dissipation and insulation measures: Regularly clean dust and oil from radiators and coolers to ensure unobstructed heat dissipation. Move air compressors to insulated indoor environments or install insulation covers. Wrap air storage tanks and outdoor pipelines with insulation cotton, and add heating tapes at key points to further reduce freezing risks.

5.Upgrade core equipment configurations: Huitong Xinda's permanent magnet variable frequency air compressors feature efficient air-cooled heat dissipation systems. By optimizing airflow circulation and fin structures, winter heat dissipation efficiency remains stable. The PLC intelligent control system monitors oil temperature, air pressure, and tank drainage status in real-time, automatically adjusting operating parameters at low temperatures to avoid high-temperature alarms.

6.Provide winter-specific maintenance services: Huitong Xinda offers winter air compressor maintenance packages. Professional technicians inspect equipment operation on-site, clean contaminants, replace aging components (e.g., filters, seals, drain valves), guide standardized No. 46 oil filling and tank drainage operations, and adjust parameters based on working conditions to ensure optimal performance in low temperatures.

IV. Significant Practical Application Results

A machinery manufacturing enterprise in Qingdao previously faced frequent air compressor high-temperature alarms and frozen/clogged air storage tanks in winter, with unplanned downtime exceeding 8 hours monthly. Under the guidance of Huitong Xinda's technical team, the enterprise replaced with No. 46 winter-specific lubricating oil, established a thrice-daily drainage system, added insulation cotton to tanks and pipelines, and thoroughly cleaned the heat dissipation system. After rectification, the equipment's winter operating temperature stabilized at 85-95°C, with no more high-temperature alarms or freezing issues. Oil consumption decreased by 25%, reducing monthly downtime losses by over 15,000 yuan. "Huitong Xinda's solution is highly targeted. Especially the selection of No. 46 oil and regular drainage recommendations completely solved our winter worries and reduced operational costs—it's very practical," commented the enterprise's equipment manager.

"Stable operation of air compressors in winter is crucial for industrial production. Huitong Xinda has always been customer-oriented, providing enterprises with full-lifecycle air supply solutions through technological innovation and professional services," stated Guo Yanling, General Manager of Huitong Xinda.
