Displacement volume is one of the important parameters of screw air compressors. The first consideration for customers when selecting an air compressor is the displacement volume. The purchased new machines are generally able to meet the company's production gas regulations, but with the increase in use time, problems such as insufficient air displacement will gradually appear. What should I do if we encounter this type of situation? I feel that if the screw air compressor is used, the exhaust volume problem occurs, so the solution is the key!

　　 1. Whether maintenance is timely. Most of the time, the decrease in compressor displacement is not a big problem. In fact, customers are negligent in maintenance. The air filter is blocked and affected by the maintenance time but not immediately. After replacing the air filter, it can be used normally. Lubricants and other filter elements are also very important. Check whether the lubricant is within the standard range. If it is lacking, please add it appropriately.

　　2. Whether the intake valve is open. If the intake valve cannot be opened during loading, it can be concluded that the decrease in the displacement of the screw air compressor is due to the failure of the intake valve, which should be removed for repair or replacement.

　　 3. Motor failure. Because a local short circuit occurs in the motor coil, or the bearing is damaged, the motor bearing is damaged, which causes the motor speed to be lower than the rated speed, and reduces the compressor displacement. The motor coil, bearing, etc. should be repaired immediately, and the compressor exhaust should be checked after the repair. quantity.

4. Changes in the environment cause the exhaust volume to drop. The higher the altitude, the thinner the gas, and the smaller the gas production per unit time; there is too much water in the air, and there is a lot of water in the compression. In the rear treatment, water vapor Precipitation, resulting in reduced exhaust gas volume.

　　5. Excessive production air consumption will also result in insufficient equipment exhaust. At this time, the problem of insufficient air supply can be solved by adding units.

Different places of use have different requirements for screw air compressors. Enterprises can choose air compressors according to their own needs.
