The working conditions of oil-free screw air compressors are often complicated, with dust, oil and various particles. Greasy dirt, carbon deposits, deposits, rust, etc. will be generated inside. Regularly clean the machine head, paint bucket, radiator, inside the tubing, and various valves to achieve the ultimate goal of eliminating safety hazards.
Oil-free screw air compressor cleaning temperature control valve, the temperature control valve is composed of valve body, valve core, temperature sensing element, spring and so on. The temperature control valve plays the role of constant temperature control. When the oil temperature measured by the temperature sensing element of the temperature control valve is lower than the action value (the action value of the temperature sensing element is generally 71 degrees), the lubricating oil returns directly from the oil and gas barrel to the main engine. When the oil temperature measured by the temperature sensing element of the control valve is higher than the action value, the thimble of the temperature sensing element of the temperature control valve will act, pushing the valve core to open the bypass valve of its own equipment, so that the lubricating oil enters the cooler for cooling (if the temperature sensing element measures The higher the temperature, the greater the opening of the bypass valve), and the cooled lubricating oil returns to the main engine.
The temperature control valve of oil-free screw air compressor has a cover on the surface, and there are screw holes on the cover. Find a suitable nut to screw in the cover, then use the circlip pliers to remove the circlip that fixes the cover, and then use the pliers Pull the nut just screwed in to take off the cover and all the internal parts. Clean all parts of the temperature control valve according to the method of cleaning the relief valve. After all the above parts are cleaned and dried, install them to the air compressor. After all parts are installed in the air compressor, check again for omissions and clean up the tools and other items used during installation.
Maintenance of temperature control valve
(1) Whether the temperature control element operates under the specified temperature.
(2) Check whether the temperature control components are broken or unsoldered.
Overhaul of oil cooler
(1) Confirm that the inlet and outlet valves of the cooling water of the air compressor are closed.
(2) Open the oil cooler drain pipe and drain the oil to the waste oil drum.
Oil-free screw air compressors have correct maintenance and maintenance methods, which play a vital role in the service life and operational reliability of oil-free screw air compressors. Air compressor cleaning is the after-sales maintenance service personnel. Always mastered skills.
