Introduction:
The oil and gas separation filter is a device that separates the gas in the lubricating oil to ensure that the lubrication system can work normally.
Application range:
Solid-liquid, gas-solid, gas-liquid separation and purification in the fields of petroleum, chemical, metallurgy, aviation, electronics, electric power, pharmaceutical, environmental protection, atomic energy, nuclear industry, natural gas, refractory materials, fire-fighting equipment, etc.
working principle:
The air compressed from the head of the compressor mains is filled with oil droplets of different sizes. The large oil droplets are easily separated by the oil and gas separation tank, while the small oil droplets (suspended) must pass through the micron-sized glass fiber filter of the oil separation filter. The material is filtered. The correct choice of glass fiber diameter and thickness is an important factor to ensure the filtration effect. After the oil mist is intercepted, diffused and polymerized by the filter material, the small oil droplets are quickly aggregated into large oil droplets, which pass through the filter layer under the action of aerodynamics and gravity, and settle at the bottom of the filter element. These oils are returned to the lubrication system through the inlet of the return line at the bottom of the filter element, allowing the compressor to discharge relatively pure, high-quality compressed air.
Precautions for replacing the filter:
When the pressure difference between the two ends of the oil and gas separation filter is 0.15MPa, it should be replaced; when the pressure difference is 0, it indicates that the filter element is faulty or the airflow has been short-circuited. At this time, the filter element is also replaced when applicable. Generally, the replacement time is 3000~4000 hours. If the environment is poor, the usage time will be shortened.
When installing the return line, it must be ensured that the tube is inserted into the bottom of the filter element. Replace the oil separator to pay attention to the electrostatic discharge. Connect the inner metal mesh to the oil drum casing.
