The Summer Air Compressor Should Pay Attention to the Environmental Temperature Problem

  • 2021-06-16

As you know, excessively high ambient temperature will become an incentive for air compressors to malfunction. Energize the air compressor and give him professional maintenance precautions: let it return to its ideal state!


1: Screw Air Compressor

Air-cooled air compressor

  • The air compressor station must be well ventilated and the indoor temperature of the air compressor station does not exceed 46°C;
  • Check the air cooler for dirt, and clean the cooler by blowing back frequently.
Water-cooled air compressor
  • Detect CTD value and its trend;
  • If necessary, clean the cooler or replace with a new cooler;
  • Check whether the inlet water temperature is lower than the rated cooling water temperature, whether the pressure is higher than the rated pressure, and check whether the cooling tower is blocked or fouled;
  • In summer, when the humidity is high, when using chilled water for cooling, pay attention that the exhaust temperature of the main engine should not be too low, otherwise the water content in the oil may exceed the standard.

In summer, the humidity is high and the amount of condensed water increases. Check whether the trap is working properly and maintain it in time; or replace the energy-saving non-destructive pneumatic valve.


Also due to the influence of humidity, the machine should be cranked when the machine is stopped for more than 24 hours to prevent the air circuit from jamming the machine due to dust accumulation, and avoiding failure to start next time, or even damage to the host.

  • The wiring terminals in the control cabinet may become loose "virtual connection" due to vibration, high temperature and other reasons after long-term use. It is recommended to check in time to avoid "misoperation" of error signals.
  • Some non-original compressor lubricants may be used in better seasons, but in high temperature and high humidity environments, certain physical and chemical indicators may deteriorate rapidly, failing to provide reliable oil film support and protection, causing coking and even main components damage . The super five types of lubricating oil supplied by the original screw compressor can adapt to all kinds of harsh operating environments and ensure the reliability of the air compressor.
  • Check that the output of the temperature control valve is stable, and if necessary, disassemble and clean it.
  • The stator and rotor shall be cleaned in time, and grease or lubricating oil shall be added in accordance with the specifications.
  • For couplings that need to be lubricated, remove the old grease, and add qualified grease in accordance with the specifications; check the coupling's alignment status, and check that the coupling connectors are in place.
