When the air compressor oil and gas separator is blocked, it can be analyzed from the following five aspects:
1. Sources of impurities
1. Air filtration problem:
1. If the air filter filter effect is not good, dust, particles and other impurities in the air will enter the air compressor system. With the flow of compressed air, these impurities may enter the oil and gas separator.
2. For example, long-term use of air compressors in dusty environments, and the air filter is not replaced or maintained in time, will lead to a large amount of dust into the system, increasing the risk of oil and gas separator clogging.
2. Lubricating oil quality problem:
1. Low quality lubricants may contain more impurities, precipitates or additive decomposition products. During the operation of the air compressor, these substances may be separated and clog the oil and gas separator.
2. For example, the use of inferior lubricating oil that does not meet the requirements of air compressors, or the contamination of lubricating oil during storage and transportation may lead to a decline in the quality of lubricating oil, which in turn affects the normal operation of the oil and gas separator.
3. Compressed air pipeline pollution:
1. If the inside of the compressed air pipeline is not clean, there are impurities such as rust, welding slag, oil and other impurities, these impurities may be sucked into the air compressor system, and eventually block the oil and gas separator.
2. For example, when installing or maintaining compressed air pipelines, without adequate cleaning and purging, impurities in the pipelines will enter the air compressor system.
2. Abnormal running parameters
1. Stress problem:
1. Too high exhaust pressure will lead to an increase in the load of the oil and gas separator, which will reduce the separation effect and easily cause blockage.
2. For example, if the exhaust pressure of the air compressor is set too high, or the exhaust pressure is abnormally increased due to the excessive resistance of the post-processing equipment, it will cause greater pressure on the oil and gas separator and increase the possibility of blockage.
3. Too low pressure may also affect the normal operation of the oil and gas separator. For example, when the suction pressure is too low, the air flow is reduced, which may lead to uneven oil and gas mixing and increase the separation difficulty of the oil and gas separator.
2. Temperature problem:
1. Too high temperature will reduce the viscosity of lubricating oil and increase the fluidity, which is easy to lead to the production of oil mist and increase the load of oil and gas separator.
2. For example, the failure of the air compressor cooling system causes the oil temperature to be too high, which will change the performance of the lubricating oil and increase the risk of blockage of the oil and gas separator.
3. Too low temperature will also affect the performance of the oil and gas separator. For example, in a cold environment, the viscosity of the lubricating oil increases and the fluidity becomes worse, which may reduce the effect of oil and gas separation and easily cause blockage.
3. Traffic problem:
1. Excessive air flow may exceed the processing capacity of the oil and gas separator, resulting in reduced separation effect and easy to cause blockage.
2. For example, in the case of a sudden increase in the load of the air compressor, the air flow increases, and if the oil and gas separator cannot adapt to this change in time, there may be blockage problems.
3. Too small air flow may also affect the normal operation of the oil and gas separator. For example, when the air compressor intake is insufficient, the oil and gas mixture is uneven, which may increase the separation difficulty of the oil and gas separator.
3. Improper maintenance of equipment
1. The replacement cycle is too long:
1. The oil and gas separator has a certain service life, and after the replacement cycle, the filtration effect will gradually decline, and the blockage problem is easy to occur.
2. For example, if the oil and gas separator is not replaced at the time interval specified by the manufacturer, it may lead to blockage and affect the normal operation of the air compressor.
2. Incorrect maintenance methods:
1. When maintaining the oil and gas separator, if the method is not correct, it may damage its internal structure and affect the separation effect.
2. For example, when cleaning the oil and gas separator, the use of inappropriate cleaning agents or cleaning methods may lead to deformation, damage, or failure of the internal coalescing material, resulting in blockage problems.
3. Ignoring routine checks:
1. If the air compressor is not regularly checked, the blockage problem of the oil and gas separator may not be found in time.
2. For example, in daily operation, if you do not pay attention to the changes in the pressure, temperature, fuel consumption and other parameters of the air compressor, or if you do not check the differential pressure indicator of the oil and gas separator, you may miss the best time to find the blockage problem.
Four, design and installation problems
1. Improper selection:
1. If the selection of the oil and gas separator is not reasonable according to the actual working parameters of the air compressor, the processing capacity of the oil and gas separator may be insufficient, and the blockage problem is easy to occur.
2. For example, if the flow rate is too small and the filtration accuracy is not high enough, the oil and gas separator may not be able to meet the working requirements of the air compressor, resulting in blockage problems.
2. The installation position is unreasonable:
1. The installation position of the oil and gas separator will also affect its working effect. If the installation is not properly located, it may lead to insufficient oil and gas separation, or be susceptible to external factors.
2. For example, installing the oil and gas separator in a position with large vibration may affect the stability of its internal structure and reduce the separation effect; Or installing it in an environment where the temperature is too high or too low may also affect its performance.
3. Pipeline connection problem:
1. If the pipeline connection between the oil and gas separator and the air compressor and other equipment is not reasonable, it may also cause blockage problems.
2. For example, the pipe diameter is too small, too much bending, not tight connection and other problems may lead to poor airflow, increase the load of the oil and gas separator, and easily cause blockage.
V. Other factors
1. Environmental factors:
1. Harsh working environment, such as high temperature, high humidity, dust, etc., may accelerate the blockage of the oil and gas separator.
2. For example, in a humid environment, the moisture in the air may mix with the lubricating oil to form an emulsion, increasing the difficulty of separating the oil and gas separator; In a dusty environment, dust is easy to enter the air compressor system and block the oil and gas separator.
2. Improper operation:
1. Improper operation of the operator may also lead to blockage of the oil and gas separator.
2. For example, frequent starting and stopping of air compressors, overload operation, and non-maintenance according to operating procedures may cause adverse effects on the air compressor system and increase the risk of blockage of the oil and gas separator.
