Ingersoll Rand oil-free screw air compressor in practical applications, the working environment of oil-free screw air compressor is actually relatively neat, because of its particularity, there will be other dust and particles in the use, resulting in The use of accessories in the machine will be greatly damaged, and thus cannot be guaranteed. Therefore, it is necessary to clean and clean the accessories of the oil-free screw air compressor, so as to eliminate the safety hazard. Usually after 1000 hours of operation or one year, the replacement interval should be shortened.

1. Screw machine cleaning air compressor · Cleaning method: first run the air compressor for a few minutes, the machine reaches normal temperature; close the air compressor, wait for the internal pressure to leak, open the internal device, pour into the air compressor cleaning agent, Tighten; open the air compressor for 30 minutes; the air compressor temperature after general cleaning will drop by about 10 degrees.

4, the relief valve (intake valve) cleaning

The unloading valve is composed of a valve body, a valve core (piston), a gas manifold block, a solenoid valve and a proportional valve (capacity regulating valve). The unloading valve mainly controls the loading of the air compressor (the screw air compressor heavy truck), the unloading (empty vehicle), and the proportional (tolerance) control function. In addition, the lubricating oil can be prevented from being ejected from the main engine when the air compressor is stopped.

Unloading valve disassembly:

(1) Remove the hose connecting the unloading valve to the air filter;

(2) Remove all other components and the air pipe connected to the relief valve;

(3) Removing the solenoid valve coil;

(4) Remove the nut assembled from the unloading valve and the main unit and remove it;

(5) Move the unloading valve to the floor covered with clean paper or related clean floor.

Cleaning and unloading valve: (Spiral air compressor cleaning agent should use soapy water, diesel oil, clean gasoline, Tianna water, etc., the above cleaning agent should be selected according to the degree of dirt, it is generally recommended to use soapy water or diesel for cleaning).
Remove the valve spool: Use a circlip to remove the circlip at the connection between the valve core and the valve body, then use the pipe wrench to unscrew the valve core, and take out the cylinder, valve, O-ring, U-ring, The spring is immersed in the cleaning agent, and then the air inlet on the valve body is removed, and the entire valve body is put into the immersion. At this time, the disassembly process of the relief valve is completed.

Cleaning: If the dirt of the intake valve is serious, replace it with a new one. When cleaning, clean the parts and wash the dirt. Wash the parts again with water. Corrosion shortens the service life of components. Parts cleaned with water should be placed in a clean place to dry to prevent rusting of iron-containing components.

Pay attention to the flatness of the surface when cleaning the valve plate and the valve body and the valve plate. The Ingersoll Rand oil-free screw air compressor is cleaned and replaced if necessary. Otherwise, the air compressor will be loaded with load (screw). When the large air compressor unit starts with load, it will not start.) Installation components: The components are installed according to the reverse steps of disassembly. It should be noted that when installing the components, the position of the sealing ring and the moving components should be coated with an appropriate amount of oil to make the sealing ring better installed and the moving parts more. flexible.

Ingersoll Rand oil-free screw air compressors have many parts for the relief valve. If you are not sure to remember the position of each part, you can install the parts after cleaning one part, but the parts should not be installed in the valve body. On top, all parts are cleaned and assembled together to the valve body. After the entire cleaning process of the relief valve is completed, it is placed next to the air compressor.
