The working environment of the oil-free screw air compressor is actually relatively tidy, because of its particularity, there will be other dust and particles entering during use, resulting in the use of accessories in the machine will be greatly damaged, and the use cannot be guaranteed Reasonable cleaning and cleaning of oil-free screw air compressor parts is very necessary to achieve the purpose of eliminating hidden dangers.
1.Clean water and gas separator
The structure of the water and gas separator of screw air compressor parts is similar to that of oil and gas tanks. The air inlet is designed against the wall and solidified into centrifugal force. Due to the weight of water and gas, it can effectively separate the moisture in the compressed air. Cleaning of water and gas separator: Remove the cover of the water and gas separator, and you can soak and clean it with a cleaning agent.
2.Unloading valve (intake valve) cleaning
The relief valve is composed of valve body, valve core (piston), pneumatic manifold, solenoid valve and proportional valve (capacity regulating valve). The load relief valve mainly controls the loading (screw air compressor heavy truck), unloading (empty truck), and proportional (capacity adjustment) control functions of the air compressor. In addition, it can prevent the lubricant from spraying out of the host when the compressor is stopped.
3.Screw cleaning
Air compressor · Cleaning method: first run the air compressor for a few minutes, the machine reaches normal temperature; turn off the air compressor, wait for the internal pressure to release, open the internal device, pour the air cleaner cleaning agent, tighten; Run for 30 minutes; The temperature of the air compressor after general cleaning will drop by about 10 degrees.
4.Cooler cleaning
In China, air coolers are generally divided into air-cooled and water-cooled, so there are different cleaning methods for different coolers.
The water-cooled cooler disassembles the cooling water inlet and outlet pipes. Inject the cleaning solution to soak or rinse with water with a pump cycle. Install the cooling water inlet and outlet pipes. When the oil cooler has serious fouling and the above methods are not ideal for cleaning, you can remove the oil cooler separately, open the two end covers, and use special cleaning steel brushes or other tools to remove the scale. When cleaning the medium side of the cooler cannot effectively reduce the temperature, the screw air compressor needs to clean the oil side, as follows:
Dismantling the gas manifold: Remove the manifold from the valve body, and there are air holes on the four sides of the manifold (the hole of the screw air compressor is used to clear the air when the integrated gas path is blocked). Unscrew the sealing nut and soak the manifold together in the cleaning agent.
Cleaning: If the dirt of the intake valve is more serious, replace it with a new cleaning agent. During the cleaning process, clean the parts first and then wash the parts with more dirt. The cleaned parts should be rinsed with water again to avoid Corrosion shortens the service life of parts. Parts washed with water should be dried in a clean place to prevent iron-containing parts from rusting.
