What is the main use of air compressor on industrial washing machine?

2026-04-15Views:

The air compressor on the industrial washing machine is mainly used to provide pneumatic power to drive the equipment to perform key operations such as cleaning and drying.. The following is a detailed analysis of its core functions:

the core role of 1. air compressor in industrial washing machine

  1. pneumatic Control and Execution
    • valve switch: Through the pneumatic solenoid valve to control the water, drainage, detergent delivery and other processes start and stop, to achieve automatic operation.
    • Cloth Flip: Use pneumatic push rod or cylinder to drive the roller forward and reverse to ensure that linen (such as bed sheets and work clothes) is turned evenly to improve the cleaning effect.
  2. Cleaning and drying aids
    • high pressure spray: The water pressure is raised to 5-10MPa by the pneumatic booster pump to form a high-pressure water flow to wash out stubborn stains (such as oil stains and pigments).
    • hot air drying: Combined with a heat exchanger, heat the compressed air to 80-120°C, blow the surface of the cloth and grass, accelerate the evaporation of water, and shorten the drying time.
  3. Special Process Support
    • steam generation: Some models inject high-temperature steam (130-150 ℃) into the washing cavity through pneumatic control steam valve, which is used for sterilization of medical cloth, laboratory work clothes and other high-demand scenes.
    • vacuum dehydration before centrifugal dehydration, the air in the drum is extracted by a pneumatic vacuum pump to form a negative pressure environment, reduce the moisture content of the cloth and grass, and improve the dehydration efficiency.

Key Parameters of 2. Air Compressor Selection

  1. pressure demand
    • general cleaning: 0.4-0.6MPa can meet the requirements of valve control and cloth turnover.
    • high pressure spray: 0.8-1.0MPa is required to ensure water penetration.
    • steam sterilization: It is necessary to provide a stable pressure of 0.6MPa to maintain the steam temperature.
  2. Flow Matching
    • select the displacement according to the size of the equipment:
      • small machine (≤ 50kg cloth grass):0.3-0.5m & sup3;/min
      • mainframe (>100kg cloth grass):0.8-1.2m & sup3;/min
    • insufficient flow will lead to delayed action (such as slow valve response), and excessive flow will increase energy consumption.
  3. Drying and Filtration Requirements
    • dryness: The pressure dew point shall be ≤-20 ℃ to avoid corrosion of pneumatic components by condensed water.
    • Cleanliness: Particulate matter diameter ≤ 5μm, oil content ≤ 0.1 mg/m & sup3; To prevent pollution of cloth grass or blockage of nozzles.

Analysis of 3. Typical Application Scenarios

  1. hotel Cloth Washing
    • demand: High frequency, large quantities of cleaning, high requirements for drying efficiency.
    • Configuration: Select variable frequency air compressor, automatically adjust the displacement according to the load, saving energy by 20%-30%.
  2. Medical Fabric Treatment
    • demand: To meet the requirements of high temperature sterilization and low pollution.
    • Configuration: Equipped with an oil-free air compressor to ensure that the oil content of the compressed air is ≤ 0.01 mg/m & sup3; to avoid the risk of cross-infection.
  3. Industrial heavy dirt washing
    • demand: deal with oil stains, metal chips and other stubborn stains, need high-pressure spray.
    • Configuration: The two-stage compressed air compressor is adopted to stably provide 1.0MPa high-pressure air source to improve the decontamination ability.

4. maintenance and optimization recommendations

  1. regular inspection
    • pressure stability: Use a pressure gauge to check once every quarter to ensure that the pressure fluctuation is ≤ ± 0.05MPa.
    • oil-water separation: Drain the condensed water from the air storage tank daily to prevent moisture from entering the pneumatic system.
  2. Energy Efficiency Management
    • frequency conversion transformation: The installation of frequency converter for old equipment can reduce no-load energy consumption by 30%-40%.
    • Pipeline optimization: Shorten the length of the trachea (≤ 5 meters), reduce pressure loss, and improve the response speed of the system.
  3. Fault Prevention
    • pneumatic component lubrication: Check the lubrication of cylinder and solenoid valve every month and add special grease.
    • Filter Replacement: Replace the filter element in time according to the instructions of the differential pressure gauge (usually ≤ 0.1MPa) to avoid clogging.

Conclusion air compressor is the core power source of industrial washing machine, its selection and maintenance directly affect the efficiency of equipment and cloth cleaning quality. It is necessary to select the appropriate model according to the specific process requirements (such as pressure, flow rate and cleanliness), and ensure the stable operation of the system through regular inspection and energy efficiency management.
