The problem of insufficient displacement of screw air compressor

Exhaust volume is one of the important parameters of screw air compressor, the customer in the selection of air compressor is the first to consider the exhaust volume. The purchase of the new machine is generally able to achieve the company's production gas regulations, but with the use of time to improve, slowly will appear insufficient exhaust volume and other problems, encountered this kind of situation how to do? Granklin think, if the use of screw air compressor equipment exhaust volume problem, so solve is the key!

1. Whether the maintenance is timely. Most of the time, the decrease in compressor displacement is not a big problem. In fact, the customer neglects maintenance, but does not maintain it immediately at the maintenance time, causing the air filter element to be blocked and affecting the displacement. After replacing the air filter element, 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 a fault of the intake valve and should be removed for maintenance 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, causing the motor speed to be lower than the rated speed, and the compressor displacement is reduced. The motor coil, bearing, etc. should be repaired immediately, and the compressor displacement should be detected after maintenance.

4, the environment changes, resulting in a decrease in exhaust volume, the higher the altitude, the thinner the gas, the smaller the gas production per unit time; too much water in the air, with a lot of water in the compression, in the rear treatment, water vapor precipitation, resulting in a decrease in exhaust volume.

5, too much production gas will also lead to insufficient equipment exhaust. At this time, the problem of insufficient air supply can be solved according to the increase of the unit.

Different places of use have different requirements for screw air compressor displacement, and enterprises can select air compressors according to their own needs.
