Pay attention to the main engine of screw air compressor
The main engine of the air compressor is like the heart of the human body. If the heart is not good, how can we do a good job? Therefore, if our air compressor host fails, timely maintenance is the best policy.
The user doesn't like the overhaul of the main engine of the air compressor, which means he needs to spend a lot of money. Therefore, many users always like to delay when they find that there is a fault in the main engine of the air compressor. The longer the delay, the more cost-effective it is for them. Is this really the case? The answer is No.
The processing of the screw, main engine shell and high and low pressure end of the air compressor is of high precision, which ensures that there is an appropriate gap between the screw and the screw and between the screw and the main engine shell after the main engine is assembled. The gap has fully taken into account the deformation of the screw and shell when the main engine runs at high temperature; With the passage of the running time of the air compressor, the bearings of the main engine will inevitably be worn, resulting in the axial displacement and radial displacement of the screw. This change will change the gap between the screw and the screw, between the screw and the main engine shell and between the front and rear end faces. The strong friction that may occur between the main engine screws, between the screws and the front and rear end faces, and between the screws and the main engine shell will sharply increase the operating load of the main engine. In addition, the operating load of the severely worn bearings is also very large. In this way, the motor will be in the overload working state, which will seriously endanger the safe operation of the motor. If the situation is serious, if the electrical protection device of the air compressor unit is insensitive or fails, it may also cause the motor to burn out. Therefore, users using screw air compressors need to pay special attention to the repair and maintenance of the host.
