The oil and gas separator is a device that separates the crude oil produced by the oil well from 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 into the annular space of the tubing and casing. Sometimes the separator is also used for the separation, buffering and metering of oil, gas, water and sediment. From the shape points generally have three forms, vertical, horizontal, spherical. The oil and gas separation element is the key component that determines the quality of compressed air in the air compressor. The high-quality oil and gas separation element can not only ensure the high efficiency of the compressor, but also filter

Oil and gas separation elements are determined.Air compressorThe key components of compressed air quality, high-quality oil and gas separation components can not only ensureCompressorefficient work, andFilter elementLife can be thousands of hours. FromCompressorThe compressed air coming out of the 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 pass through oil and gas separation.Filter elementMicron and glass fiber filter layer filtration. The oil particles are directly intercepted by the filter material through the diffusion effect of the filter material and the mechanism of inertial collision condensation, so that the suspended oil particles in the compressed air quickly coagulate into large oil droplets. Under the action of gravity, the oil accumulates at the bottom of the oil core and returns to the head lubricating oil system through the inlet of the oil return pipe at the bottom recess, thus enabling the compressor to discharge more pure oil-free compressed air. The solid particles in the compressed air pass through the oil core and stay in the filter layer, which leads to the increasing pressure difference (resistance) of the oil core. With the increase of the use time of the oil core, when the pressure difference of the oil core reaches 0.08 to 0.1Mpa, the filter element must be replaced, otherwise the operating cost (power consumption) of the compressor will be increased.
Oil-gas separator replacement method
1. built-in models:
1.Air compressorStop the machine, close the air pressure outlet, and open the drainValveConfirm that there is no pressure in the system.
2. Disassemble the pipeline above the oil and gas barrel and maintain the pressure at the same timeValveRemove the outlet line 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 barrel.
5. Remove the oil-gas separator and replace it with a new one.
6. Install it in the reverse order of disassembly.
2. external models:
Shut down the air compressor, close the air pressure outlet, open the drain valve, and remove the old oil-gas separator and replace it with a new one after confirming that there is no pressure in the system.
Safe use
1. There is a safety valve on the end cover of the oil tank of the air compressor. When the air pressure in the oil tank reaches 1.1 times of the set value, the safety valve will automatically open to release part of the air and reduce the air pressure in the oil tank. Check the safety valve method is in the compressor full load work, gently pull the safety valve on the vent rod, if the safety valve can exhaust, it is considered normal.
2. The oil tank is equipped with a pressure gauge, which detects the pre-filter pressure. The bottom of the oil tank is equipped with a drain valve. The drain valve should be opened regularly to drain 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 position 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. The oil sub-tank belongs to a pressure vessel and must be produced by a professional manufacturer with manufacturing qualifications. Each tank has a unique number and certificate of conformity.
