Screw air compressor is generally used for several years

The service life of screw air compressor is generally in 5 to 15 years the specific life is affected by multiple factors such as equipment quality, use environment, maintenance and operation specifications. The following is a detailed analysis:

factors influencing the useful life of 1.

1. Equipment quality
   • core Components the material and process of the screw rotor determine the life. The life of the imported high-end model rotor can reach 15 years, while the ordinary model may only be 5 years.
   • Brand and Manufacturing Process: Well-known brands use high-quality materials and precision processing, with lower equipment failure rate and longer life.
2. Use of the environment
   • harsh environment: High temperature, high humidity, and dusty environment will accelerate equipment aging and shorten life. For example, salt spray corrosion in coastal areas may lead to early scrapping of equipment.
   • Installation conditions: The equipment should be placed in a ventilated, dry and clean environment, avoiding direct sunlight and high temperature baking.
3. Maintenance
   • regular maintenance: Replace the filter element and lubricating oil on time, and clean the cooling system, which can extend the life by 30%-50%.
   • Maintenance quality: The use of inferior lubricating oil or expired filter elements may cause rotor wear, carbon deposits, and shorten life.
4. Operation Specification
   • correct operation: Avoid frequent start and stop, overload operation, can reduce equipment loss.
   • Parameter setting reasonably set pressure, temperature and other parameters to avoid long-term operation of equipment under high load.

2. ways to extend life

1. equipment selection
   • choose a high-end brand: Such as Atlas, Ingersoll Rand, etc., its screw rotor adopts special alloy, longer life.
   • Matching requirements: Select the appropriate power model according to the gas consumption to avoid "big horse-drawn trolley" or overload operation.
2. Environmental optimization
   • control temperature and humidity: Install air conditioner or dehumidifier, keep the ambient temperature ≤ 35 ℃, humidity ≤ 60%.
   • air purification: Install a high-efficiency filter at the air inlet to reduce the entry of dust and impurities.
3. Maintenance Plan
   • daily inspection: Observe the oil level, leakage, abnormal noise, etc.
   • Regular maintenance: Replace the oil filter and air filter every 2000-4000 hours, and replace the lubricating oil every 8000 hours.
   • Annual Overhaul: Check the bearing, seal and other wearing parts, and replace them in time.
4. Operation training
   • professional training: Operators need to understand the principle of the equipment to avoid misoperation.
   • Specification process: Develop standard procedures for startup, shutdown and fault handling.

3. Replacement Decision Basis

replacement shall be considered when the following conditions occur:

1. maintenance cost is too high: If the maintenance cost exceeds 40% of the price of the new machine, it is recommended to replace it.
2. Performance degradation: Gas production decreased by more than 20%, or energy consumption increased by 30%.
3. Security risks: Oil leakage, air leakage, high temperature and other danger signals appear.

Summary: The life of the screw air compressor can be extended to more than 10 years through high-quality selection, optimized environment, strict maintenance and standardized operation. Enterprises should develop maintenance plans based on actual operating conditions and weigh the timing of replacement between economy and performance.
