(Summary description)The oil and gas separator is a device that separates the crude oil produced by the oil well and the associated natural gas. The oil and gas separator is placed between the submersible centrifugal pump and the protector to separate the free gas in the well fluid from the well fluid, the liquid is sent to the submersible centrifugal pump, and the gas is released to the annular space of the tubing and casing.


Sometimes the separator is also used for multiphase separation, buffering and metering of oil, gas, water and sediment. There are generally three forms from the shape, vertical, horizontal, spherical.

The oil and gas separation element is the key component that determines the quality of the compressed air of the air compressor. The compressed air from the compressor head entrains large and small oil droplets. Large oil droplets are easy to separate when passing through the oil and gas separation tank, while small oil droplets (suspended oil particles below 1um in diameter) must be filtered through the micron and glass fiber filter material layers of the oil and gas separation filter element. Through the diffusion of the filter material, the oil particles are directly intercepted by the filter material and the mechanisms such as inertial collision agglomeration make the suspended oil particles in the compressed air quickly agglomerate into large oil droplets. The inlet of the oil return pipe in the recess returns to the lubricating oil system of the machine head, so that the compressor discharges purer and oil-free compressed air. When the solid particles in the compressed air pass through the oil separation core, they stay in the filter layer, which leads to the continuous increase of the pressure difference (resistance) of the oil separation core. With the increase in the use time of the oil separator, when the pressure difference of the oil separator reaches 0.08 to 0.1Mpa, the filter element must be replaced, otherwise the compressor operating cost (power consumption) will be increased.

How to replace oil and gas separator

1. Built-in models:

1. Stop the air compressor, close the air pressure outlet, open the drain valve, and confirm that the system has no pressure.

2. Disassemble the pipeline above the oil and gas barrel, and at the same time remove the pipeline from the outlet of the pressure maintenance valve to the cooler.

3. Remove the oil return pipe.

4. Remove the fixing bolts of the cover on the oil and gas barrel, and remove the upper cover of the gas barrel.

5. Remove the oil and gas separator and replace it with a new one.

6. Install in the reverse order of disassembly.

2. External models:

Stop the air compressor, close the air pressure outlet, open the drain valve, and after confirming that the system has no pressure, remove the old oil and gas separator and replace it with a new one.

safe to use

1. There is a safety valve on the end cover of the air compressor oil sub-tank. When the air pressure in the oil sub-tank reaches 1.1 times the set value, the safety valve will automatically open, let out part of the air, and reduce the air pressure in the oil sub-tank. The way to check the safety valve is to lightly pull the relief lever on the safety valve when the compressor is working at full load. If the safety valve can exhaust air, it is considered normal.

2. A pressure gauge is installed on the oil separation tank to detect the pre-filter pressure. The bottom of the oil tank is equipped with a drain valve, which should be opened regularly to release the water and dirt deposited at the bottom of the oil tank.

3. There is a transparent oil level mirror next to the oil tank to show the level of the oil tank. The correct oil level is that when the air compressor is working normally, the oil level is in the middle of the upper and lower degrees. If it is too high, it will run away, and if it is too low, it will affect the safety of the whole machine.

4. Oil separation tanks are produced by professional manufacturers that must have manufacturing qualifications for pressure vessels. Each oil tank has a unique number and certificate.
