Thread Content
From now on, in order to strengthen exchanges with sea friends, we have launched a [Daily Question] activity in the Animal Equipment Technology Edition. We hope that everyone will actively participate and make progress and improvement together! ! ! award: Actively participate in 3 points of wealth, answer intact 10-15 wealth. This question is valid for two days. No marks will be given for more than two days. The previous section talked about the equipment in the lubrication system. Please look at the picture below. What kind of refrigeration equipment is this and what is its function?

It is the oil content of the screw machine. Its function is to separate oil and gas. The principle is the filtration type among filtration type, centrifugal type and washing type.

This equipment is an oil separator for screw machines； The function is: Oil and gas separation ； The principle is: Filter type, centrifugal type, and washing type.
Horizontal oil separator for screw compressor； The most common forms and structures currently include: There are four structural types: washing type, centrifugal type, filtering type, and packing type. Most screw refrigeration compressors adopt a rotor oil injection structure. Oil injection into the working chamber has three functions:: 1. Cooling ； 2. Lubrication ； 3. Sealing. Working principle: The high-pressure, high-temperature (about 80°C) oil and gas mixture coming out of the main engine enters the oil separation tank along the tangential direction inside the oil separation tank. Under the action of centrifugal force, most of the oil in the oil and gas mixture is thrown to the inner wall of the oil separation tank, and flows along the inner wall to the bottom of the oil separation tank under the action of gravity. Another part of the oil droplets condensed into large oil droplets during the collision with each other, and finally sank to the bottom of the oil separation tank under the action of gravity, continuing to participate in the cycle. The air filtered by the oil separator passes through the minimum pressure maintenance valve, flows to the rear cooler for cooling, and then is discharged from the air compressor.

Horizontal oil separator. Four common oil separators: Washing type, centrifugal type, filtering type, and packing type. In the picture, there is a silencer but no packing, filter, etc. It is probably the centrifugal type. effect: Separates lubricating oil from the air. principle: Air and lubricating oil are sprayed out in a tangential direction. Under the action of centrifugal force, larger oil droplets hit the container wall and flow down. Smaller oil droplets collide and form large oil droplets during their movement.
The oil and gas separator is a key component that determines the quality of the compressed air of the air compressor. High-quality oil and gas separation components not only ensure the high efficiency of the compressor, but also the filter element life span can reach thousands of hours. Compressed air entrainment from the compressor head * * Tiny droplets of oil. Large oil droplets are easy to separate when passing through the oil and gas separation tank, while small oil droplets (suspended oil particles with a diameter of less than 1um) must be filtered through the micron and glass fiber filter material layers of the oil and gas separation filter element. The oil particles are directly intercepted by the filter material due to the diffusion effect of the filter material and the mechanism of inertial collision and agglomeration makes the suspended oil particles in the compressed air quickly condense into large oil droplets. Under the action of gravity, the oil gathers at the bottom of the oil separator core and returns to the machine head lubricating oil system through the oil return pipe inlet at the bottom recess, thereby allowing the compressor to discharge purer, oil-free compressed air. The solid particles in the compressed air are retained in the filter layer when passing through the oil separator core, which causes the pressure difference (resistance) of the oil separator core to continuously increase. As the use time of the oil separator increases, when the pressure difference of the oil separator reaches 0.08 to 0.1Mpa, the filter element must be replaced, otherwise the operating cost (power consumption) of the compressor will increase.
