Too much water in screw air compressor

Too much water in the screw air compressor is a common problem, which may be caused by a variety of reasons. The following is a detailed analysis of this problem and the corresponding solutions:

cause analysis

1. high air humidity: When the air humidity is high, it will form a supersaturated situation after being compressed, and the moisture in the air will become liquid.
2. Blockage of drainage system: The automatic drainage system of the air compressor or the automatic drainage system of the air storage tank is blocked, resulting in the water can not be discharged in time.
3. Dryer failure or insufficient capacity: If a dryer is installed but does not work normally, or the capacity of the dryer is not enough to handle all the moisture generated by the compressor, it will cause excessive moisture in the air.
4. Cooling system fault: The cooling system may leak or malfunction, causing moisture to enter the compressor.
5. Air intake and air filter problems: If the air inlet or air filter is contaminated or blocked, it may cause humid air to be sucked into the compressor, thereby increasing the internal moisture.
6. Equipment selection or improper use: For example, the air compressor selection is too large and the gas consumption is very small, resulting in a serious low operating load rate, the oil temperature may not reach 80 ℃ for a long time, or even lower than the dew point, so that the moisture in the compressed air condenses into liquid and stays inside the air compressor.

Solution measures

1. regular inspection and maintenance of drainage system: Ensure that the drainage system of the automatic drain or gas storage tank is unobstructed, and manually drain or check the working condition of the automatic drain regularly.
2. Inspection and maintenance of dryer: Ensure that the dryer works normally, and adjust or replace the dryer as needed. If the capacity of the dryer is insufficient, consider adding a dryer or optimizing its configuration.
3. Check and repair the cooling system: Regularly check the tightness and integrity of the cooling system, repair any leaks in time, and ensure the normal circulation of the coolant.
4. Cleaning and replacing air filters: Clean and replace the air filter regularly to ensure the smooth flow of the air inlet and reduce the entry of humid air.
5. Optimize equipment selection and use when selecting an air compressor, it should be selected according to the actual gas consumption to avoid excessive selection and low operating load rate. For the purchased air compressor, if it is found that the air consumption is much less than the design capacity of the air compressor, the water condensation can be reduced by adjusting the operating parameters (such as no-load time, temperature setting, etc.).
6. Regular discharge of condensate: According to the use of equipment, environmental conditions and moisture content to determine the drainage cycle, it is usually recommended to discharge once a week, in high temperature or high humidity climate should increase the number of emissions.
7. Keep the environment dry and ventilated: Maintain a good ventilation and dry environment around the air compressor to avoid the influence of humid air on the air compressor.

Through the comprehensive application of the above measures, the problem of excessive moisture in the screw air compressor can be effectively solved, and the normal operation and service life of the air compressor can be ensured.
