(5) Compressed air with oil can cause the activated alumina oil to poison and fail. The super coolant used in the screw air compressor has high thermal conductivity and is used to cool the compressed air. However, the separation from the compressed air is incomplete, and the compressed air sent to the air compressor will be oiled. The oil in the compressed air will be attached to the active air. The surface of the alumina ceramic ball blocks the capillary pores of the activated alumina, causing the activated alumina to lose its adsorption capacity and causing oil poisoning and losing the function of adsorbing moisture.
Solution: Replace the oil separator core and the rear degreasing filter on time to ensure the oil and gas separation of the air compressor is complete, and the rear degreasing filter is well degreased. In addition, the super coolant in the unit must not exceed the amount.
(6) The air humidity changes greatly, and the drainage frequency and drainage time of each timing drain valve are not adjusted in time, so that more and more water can be accumulated in each filter, and the accumulated water can be brought into the compressed air.
Solution: The drainage frequency and drainage time of the timing drain valve can be set according to the air humidity and experience. If the air humidity is high, the frequency of drainage should be increased, and the drainage time should be increased. The adjustment standard is to observe that every time the drainage is drained, the accumulated water can be drained without discharging compressed air. In addition, the conveying pipeline is insulated, steam is accompanied by heat; the drain valve is added at the low point, and the inspection and drainage are carried out regularly. This measure can prevent the winter freezing pipe and remove part of the moisture in the compressed air to reduce the compressed air. User impact. By analyzing the cause of the compressed air with water, and taking the above corresponding measures to solve.
