Screw air compressors play a key role in industrial production in all walks of life. However, many companies often encounter the problem of high equipment temperature when using air compressors, which will not only affect production efficiency, but may also lead to Therefore, understanding the causes of high temperature of screw air compressors and efficient solutions is crucial for enterprises and stable operation. This article will deeply analyze the common causes of high temperature of screw air compressors and the corresponding measures to solve them, helping enterprises reduce the risks brought by high temperature of air compressors.
Screw air compressors often have high temperatures in industrial production due to high ambient temperature, insufficient lubricating oil, radiator blockage and other problems, affecting the efficiency and life of the equipment. To solve the high temperature problem, it is necessary to maintain stable operation of the equipment by improving the ventilation of the air compressor room, regularly checking the lubricating oil, cleaning the radiator, ensuring the normal operation of the temperature control valve, and replacing the oil filter. Through daily maintenance and correct operation, enterprises can effectively prevent high temperature of air compressors and ensure production efficiency and equipment life.
Causes of high temperature in screw air compressor
The ambient temperature is too high
The operating ambient temperature of the air compressor is significantly affected by this. Screw air compressors usually require the working ambient temperature not to exceed 45℃. In the hot summer, the operating environment temperature of the air compressor often easily exceeds this upper limit, resulting in equipment shortening difficulties and the occurrence of In addition, the ventilation conditions in the air compressor room also directly affect the cooling effect. If the ventilation is poor and heat accumulates, it is easy to cause the problem of temperature rise.
Insufficient lubricating oil or quality problem
Lubricating oil plays a dual role of lubrication and cooling in the air compressor. If the amount of lubricating oil is insufficient or the oil quality is reduced, it will affect the cooling effect and cause the temperature to rise. Especially when the equipment is running under high load, the lubricating oil is easy to oxidize or In addition, the use of inferior lubricating oil or lubricating oil that is not suitable for the current environment (such as too low or too high viscosity) will also cause high temperature of the air compressor.
Not cleaning the evaporator
The cleanliness of the evaporator is crucial to the evaporation efficiency of the air compressor. If the evaporator surface is worn, clogged with oil, and the air circulation is not smooth, the evaporator effect will be significantly reduced, causing the equipment temperature to rise. If the evaporator is not cleaned for a long time, it will also cause internal scaling, further reducing efficiency.
Temperature control valve failure
The temperature control valve is used to adjust the temperature of the lubricating oil to ensure the cooling effect of the valve. If the temperature control fails or fails, the lubricating oil will not flow normally to the cooling position, resulting in abnormal temperature rise. The failure of the temperature control valve may be due to long-term use of stuck or internal sensor failure.
Oil filter or oil separator blockage
The main function of the oil filter and oil separator is to filter the interruption in lubrication and ensure the smooth flow of the oil circuit. Once the oil filter or oil separator is blocked, the oil flow will decrease, the lubrication and cooling effect will decrease, and the temperature will rise. Failure to clean the filter element for a long time will aggravate the blockage of the oil circuit and make the high temperature of the equipment more serious.
Motor overload
The motor of the air compressor will generate a lot of heat when working under overload, causing the overall temperature of the equipment to rise. Motor overload may not only cause high temperature of the motor, but also affect the internal temperature of the air compressor. When the motor current or long-term high load affects the operation, it will cause abnormal temperature rise.
Solution to high temperature of screw air compressor
In order to solve the problem of high temperature of air compressor, the following are common treatment measures that help improve the operating efficiency and service life of the air compressor.
Improve the operating environment and maintain ventilation
The operating environment of the screw air compressor is crucial, so the ventilation condition of the air compressor room should be optimized:
Strengthen ventilation
Install ventilation equipment such as exhaust fans or dedicated air exchange systems in the air compressor room to ensure air circulation.
Install air conditioners
In the hot summer environment, install air conditioners in the air compressor room to reduce the ambient temperature of the equipment.
Avoid direct sunlight
Avoid direct sunlight in the air compressor room, keep the ambient temperature within a reasonable range, and prevent drought difficulties caused by the increase in temperature of young children.
Regularly check the amount and quality of lubricating oil
The quality of lubricating oil is directly related to the cooling effect, so the amount and quality of lubricating oil need to be checked regularly:
Maintain the oil level
Ensure that the lubricating oil level is within the normal range, and add lubricating oil in time when it is insufficient.
Regular replacement
Follow the coolant replacement cycle recommended by the manufacturer to avoid failures caused by oil deterioration.
Choose the right coolant
Choose a coolant suitable for the current season and temperature to avoid a decrease in effect due to oil quality mismatch.
Insufficient cleaning, keep it unobstructed
The cleanliness of the blockage directly affects the effect, so regular cleaning is required:
Regular cleaning
Use compressed air or a soft brush to clean the dust and oil on the ground and keep the air on the ground flowing.
Avoid freckle cleaning agents
Avoid using strong freckle cleaning agents when cleaning to prevent damaged nutrients.
Check the status of the stop
Check the working status of the stop regularly. If aging or serious blockage is found, it should be replaced in time.
Ensure the normal operation of the temperature control valve
The normal operation of the temperature control valve plays an important role in the temperature control of the equipment, and its status should be checked regularly:
Check whether the temperature control valve is stuck
The sticking of the cooling temperature control valve will cause the lubricating oil to fail to work properly, and it is necessary to check whether it is stuck regularly.
Replace the faulty temperature control valve in time
If the temperature control valve is found to be malfunctioning, it should be replaced in time to ensure the normal operation of the lubricating oil.
Cleaning
The internal failure of the temperature control valve may cause it to be lost, and it should be ensured regularly that it cannot operate normally.
Clean or replace the oil filter and oil separator
The regular replacement and cleaning of the oil filter and oil separator is conducive to ensuring the smooth flow of the oil circuit and ensuring the cooling effect.
Regularly replace the filter element
Regularly replace the oil filter and oil separator filter element according to the usage and manufacturer’s recommendations to avoid oil circuit siltation.
Check the filter element status
Observe the condition of the oil filter and oil separator to ensure that the oil circuit is not obstructed and avoid high temperature caused by cooling failure.
Keep the oil circuit unobstructed
If the oil filter or oil separator is blocked, it should be cleaned in time to ensure that the lubricating oil can flow normally.
Avoid motor overload and control the burden
The motor load will affect the temperature of the air compressor and needs to be kept within a reasonable range.
Monitor current fluctuations
Regularly detect the working current of the motor to avoid excessive burden due to excessive current.
Check the motor circuit
Regularly check the electrical circuit of the motor to ensure the normal operation of the motor and avoid high temperature caused by circuit failure.
Avoid overload work
Control the use load of the motor, and the high load state for a long time to reduce the high temperature problem caused by overload.
Daily maintenance: measures to prevent high temperature of air compressor
Effective prevention of high temperature problems requires daily maintenance and inspection. The following measures can help enterprises prevent high temperature problems in daily life.
Regular inspections
Check lubricating oil, equipment, temperature control valves, etc. every week or month to ensure that the equipment is operating normally.
