Impacts of Excessively High or Low Ambient Temperature and Oil Temperature on Air Compressors
This article mainly discusses the impacts of excessively high or low ambient temperature and oil temperature on air compressors, which are introduced in two parts: the impacts under high ambient temperature and high oil temperature, and the impacts under low ambient temperature and low oil temperature.
Impacts of Excessively High Ambient Temperature and Oil Temperature on Air Compressors
(1) Excessively high temperature of intake gas reduces displacement.
(2) High gas temperature during compression increases power consumption and lowers productivity.
(3) Excessively high cylinder temperature causes carbonization of lubricating oil on air valves and piston rings, resulting in loss of lubrication. There exists an explosion risk if sparks occur.
High cylinder temperature also leads to poor operation of piston rings, air valves, packing and other components, aggravating wear and causing sealing failure.
(4) Overheating may burn out bearings and bearing shells, and even disable the compressor.
(5) Overheated components suffer reduced mechanical strength and may deform.
(6) Excessively high oil temperature lowers oil viscosity and oil pressure, impairing lubrication performance.
(7) Excessively high cooling water temperature weakens the cooling effect.
(8) Overheating of electric motors and internal combustion engines may lead to burnout.
Impacts of Excessively Low Ambient Temperature and Oil Temperature on Air Compressors
(1) Excessively low cooling water temperature hinders cooling water circulation. If the temperature drops below 0°C, freezing may occur and crack equipment.
(2) Low lubricating oil temperature makes it difficult to start internal combustion engines.
Therefore, operators shall judge whether the compressor operates normally according to temperature variations, and keep the temperature of each component within the specified range to maintain stable compressor operation. This is essential knowledge that all compressor operators need to master.
