Oil-free air compressor is a commonly used compressed air equipment, which is widely used in many industrial fields because of its oil-free lubrication characteristics. In the process of use, oil-free air compressors may have various failures, and need to be repaired and maintained. The following will detail the models of oil-free air compressors and common maintenance methods.
First, oil-free air compressor model introduction
1. Model 1: Screw type oil-free air compressor
Screw type oil-free air compressor is an efficient, low noise, stable and reliable oil-free air compressor. It adopts the principle of screw compression, and compresses the compressed air through the double-sided mesh of the screw, and cools the compressed air through the cooling system to achieve a stable outlet pressure. In the maintenance process, it is necessary to check the wear degree of the screw regularly, if the wear is serious, it needs to be replaced.
2. Model 2: turbo-type oil-free air compressor
The turbine type oil-free air compressor adopts the working principle of turbine impeller, which compresses the air through the high-speed rotating impeller and then outputs it after cooling by the cooling system. In the maintenance process, it is necessary to check the wear condition of the turbine impeller frequently. If it is found that the efficiency is reduced due to serious wear, it needs to be replaced.
3. Model 3: Centrifugal oil-free air compressor
Centrifugal oil-free air compressor is a kind of air compressor that adopts the centrifugal principle for compression. It compresses the air through a high-speed rotating centrifugal structure and is cooled by a cooling system. When carrying out maintenance, it is necessary to check whether the bearings and seals of the centrifugal structure are worn, and replace them in time if necessary.
Second, the common maintenance methods of oil-free air compressors
1. Gas-liquid separator fault maintenance
The gas-liquid separator in the oil-free air compressor is the key to separating the liquid in the air. If the gas-liquid separator fails, it will lead to more liquid in the compressed air, affecting the normal operation of the compressor. In this case, check whether the drainage valve of the gas-liquid separator is normal, and clean or replace it if necessary.
2. Cooling system failure maintenance
The cooling system in the oil-free air compressor plays the role of cooling the compressed air. If the cooling system fails, the temperature of the compressed air will be too high, which will affect the normal operation of the air compressor. During maintenance, it is necessary to check whether the radiator of the cooling system is blocked, and if necessary, clean or replace it.
3. Pressure sensor failure maintenance
The pressure sensor in the oil-free air compressor is used to monitor the pressure of the compressed air. If the sensor fails, the pressure value cannot be accurately monitored and the stability of the air compressor is affected. During maintenance, it is necessary to check whether the connection of the pressure sensor is loose, and adjust or replace it if necessary.
4. Motor failure maintenance
The motor of the oil-free air compressor is its power source, and if the motor fails, it will cause the air compressor to not operate normally. During maintenance, it is necessary to check the insulation of the motor and whether the bearing is worn, if necessary, insulation treatment or replacement of the bearing.
5. Filter failure maintenance
The filter in the oil-free air compressor is used to remove impurities and particles in the air. If the filter fails, it will lead to more impurities in the compressed air, affecting the working effect of the air compressor. During maintenance, it is necessary to check the cleanliness of the filter regularly and clean or replace it if necessary.
To sum up, there are many models of oil-free air compressors, and each model needs to pay attention to different parts and systems in the maintenance process to ensure its normal operation. The maintenance should be analyzed and treated according to the specific fault, so as to extend the service life of the oil-free air compressor.
