Maintenance of screw compressor
Compared with the piston compressor, the screw compressor has a much lower probability of failure, but if the use and maintenance are improper, the advantages of the screw compressor will be difficult to achieve. Many users of piston compressors began to switch to screw air compressors. Because they did not understand the use and maintenance of screw compressors, frequent failures occurred, which caused conflicts between users and enterprises. Therefore, before using the screw compressor, you must carefully read the instructions on its use and maintenance.
There are guiding suggestions for the installation place of the machine, the ventilation volume of the air compressor station, the specifications of the power supply cable and the air switch, the water supply pressure and flow, and the size of the exhaust pipe. The operation manual will also describe the principle and structure of the machine in detail. Those who have a certain basic knowledge of electromechanics can make correct judgments and treatments of common problems through careful reading. Also, the consumable parts of the screw compressor should be replaced regularly, mainly including lubricating oil, oil filter, intake filter, oil filter element, etc. It is worth noting that the frequency of replacement in different environments is also different, so Make daily use and inspection records for screw compressors. 100 air compressor
Transmission mode of screw compressor
Gear and belt drive
In the transmission system of an air compressor, it can be generally divided into direct transmission and belt transmission. For a long time, which is better than the other has been one of the focus of debate in the industry. The direct drive of the screw air compressor means that the motor main shaft drives the rotor through the coupling and the gearbox, which is actually not a direct drive in the true sense. The real direct drive means that the motor and the rotor are directly connected (coaxially) and the speed of the two is the same. This situation is obviously very rare. Therefore, the view that direct drive has no energy loss is wrong. 100 air compressor
Another transmission method is belt transmission, which allows the speed of the rotor to be changed through pulleys of different diameters. The belt drive system discussed below refers to an automation system representing the latest technology that meets the following conditions:
1. The belt tension in each running state reaches the optimal value
2. By avoiding excessive starting tension, the working life of the belt is greatly extended, and the load on the motor and rotor bearings is reduced at the same time;
3. Always ensure the correct pulley connection;
4. It is very easy and quick to replace the belt, and it does not need to adjust the original setting;
5. The entire belt drive system runs safely and without failure. 100 air compressor
