55220273360 industrial screw air compressor compression oil separator filter

The 55220273360 industrial screw air compressor compression oil separator filter is a core oil and gas separation component developed specifically for corresponding specifications of oil injected screw air compressors. It is installed inside the oil and gas separation cylinder on the exhaust side of the air compressor main engine, and performs ultimate purification on the oil containing compressed air discharged from the main engine. It efficiently intercepts and separates micron sized oil mist particles suspended in the compressed air, greatly reducing the oil content of the compressed air. It is a key core component that determines the final output compressed air quality of the screw air compressor and ensures the stable operation of the back-end gas equipment. It is suitable for the routine maintenance and filter element replacement scenarios of corresponding models of industrial screw air compressors.

The oil separation filter element adopts a combination structure of multi-layer gradient composite fiberglass filter material and high-precision stainless steel support inner network. From the outside to the inside, a coarse separation layer, a fine separation layer, and a polymer layer are sequentially set up to intercept oil mist particles of different sizes step by step. Suspended oil particles with a diameter of less than 1 μ m are fully aggregated into large oil droplets, which fall back to the bottom of the oil and gas separation cylinder under the action of gravity and are sent back to the air compressor host for recycling through the return pipeline; The overall filtration accuracy is stable, and the residual oil content of the processed compressed air can be controlled within 3ppm. The filter element has a large overall pollutant holding capacity, and its service life can reach thousands of hours under normal working conditions; The end cover adopts a deformation resistant and high-strength structural design, matched with a high-temperature and oil resistant sealing gasket, which will not cause sealing failure or aging and peeling of the gasket in the long-term high-temperature and high-pressure operating environment of the air compressor; The internal configuration of the filter element is equipped with a built-in oil return pipe, which is precisely connected to the original oil return pipeline of the air compressor, ensuring that the lubricating oil separated by agglomeration can smoothly flow back to the main engine without accumulating inside the filter element and affecting the separation efficiency.

This product is widely compatible with the replacement and maintenance scenarios of oil and gas separation filters for corresponding specifications of oil injected screw air compressors. It can be used for screw machine maintenance in industrial production air compression stations, power air source purification in automated production lines, oil-free compressed air pretreatment in the spraying industry, air supply matching in the textile and light industry, and daily maintenance of air compression systems in general manufacturing enterprises. It is particularly suitable for gas usage scenarios with clear restrictions on the oil content of compressed air, precision pneumatic components connected to the rear end, or high requirements for air source cleanliness. It can effectively reduce the oil content of compressed air and minimize the blockage and failure of precision components caused by oil mist adhesion in the rear end.

Compared to conventional alternative oil separation filters, this product uses gradient composite fiberglass filter material, with separation accuracy gradually increasing layer by layer. The oil mist interception and coalescence efficiency is more stable, and the residual oil content in compressed air will not significantly increase after long-term operation, resulting in a longer service life; Built in full bore stainless steel support internal network, which will not cause filter element deformation or filter material collapse under high air pressure impact of the air compressor, greatly improving operational reliability; The sealing structure of the end cap is fully compatible with the corresponding model of air compressor oil cylinder chamber, and there is no sealing gap after installation, completely avoiding unfiltered oil containing compressed air from directly bypassing into downstream pipelines; Optimizing the structural design of the oil layer, the separated lubricating oil can quickly gather and fall, without forming an oil film inside the filter material to block the breathable pores. After long-term operation, the initial pressure difference rises more smoothly, which can effectively reduce the energy consumption of the air compressor operation.

After the operation of the air compressor, the oil content in the compressed air significantly exceeds the standard. First, check if there is any blockage in the oil return pipeline at the bottom of the filter element. After cleaning and clearing the oil return pipeline, normal oil return can be restored. If the oil return status is normal, it indicates that the filter element and filter material have reached their service life limit. After stopping the machine to release pressure, replace the new oil filter element to control the oil content within the standard range; After running for a period of time, the pressure difference between the front and rear of the filter element rises too quickly. Check whether the lubricating oil of the air compressor has serious oxidation and deterioration. Replace the qualified special air compressor oil and then synchronously replace the new filter element, which can effectively delay the clogging speed of the filter element; After installation, if there is oil mist leakage at the joint surface position, check whether the end cap sealing gasket has been displaced or scratched during installation, readjust the sealing gasket position to ensure complete fit with the cavity end face, and then evenly tighten the gland bolts to eliminate leakage; Abnormal high-frequency vibration occurs during the use of the filter element. Check if the internal support structure is loose. After stopping the machine and releasing pressure, disassemble and remove the filter element. After confirming that the internal structure is intact, reinstall it correctly to eliminate the vibration.
