How does air oil separator work?

The operation of an air oil separators revolve around the principle of coalescence. As exhaust air containing oil droplets enters the separator, it encounters specialized filtration media. These media encourage the small oil droplets to merge and form larger particles. As these particles grow in size, they become heavier than the air, causing them to separate from the air stream. The cleaned air, largely free of oil contaminants, is then released into the environment or directed to downstream processes.

Is air oil separator necessary?

Absolutely. The necessity of air oil separators is paramount in vacuum pump systems. They prevent oil carryover from vacuum pumps, maintaining the purity of the surrounding environment and safeguarding downstream equipment. Industries that rely on vacuum systems, such as manufacturing, research, and medical applications, benefit from air oil separators to ensure process integrity and maintain environmental standards.

Air oil separator purpose:

The primary purpose of an air oil separator is to maintain cleaner air quality within vacuum pump systems. By effectively capturing and separating oil particles from exhaust air, it prevents the release of oil contaminants into the environment or downstream processes. This preservation of air quality is vital for maintaining a healthy work environment and adhering to environmental standards.

Benefits of air oil separator:

The benefits derived from using an air oil separator extend beyond cleaner air quality. One significant advantage is the extension of the vacuum pumps’ operational lifespan. By minimizing oil-related wear and preventing oil contamination, these separators contribute to the durability and efficiency of the pumps. Moreover, air oil separators reduce the frequency and intensity of maintenance requirements, translating into cost savings and improved system uptime. Additionally, downstream equipment efficiency is enhanced as the risk of oil contamination is mitigated. This factor is particularly crucial in industries where product quality is paramount. Lastly, the use of air oil separators ensures regulatory compliance by minimizing oil emissions and environmental impact, aligning with environmental standards and regulations.

What Does an Air Oil Separator Do?

In essence, an air oil separator efficiently captures and separates oil droplets or mist from vacuum pump exhaust air. This crucial function prevents oil contamination, maintains air quality, and safeguards both equipment and processes from potential harm.

Burning air oil separators in cold weather

There are many air compressors with low flow rates that are not designed with temperature control valves. When the temperature is low in winter, the viscosity of the engine oil becomes thicker and thicker, and the oil flows slowly. When the machine is started again after being stopped for a period of time, most of the oil in the cooler has flowed into the oil drum due to the shutdown. Because there is no bypass oil circuit to supply oil in time when the main engine is rotating, the oil needs to go through the cooler, oil filter, oil cut-off valve, etc. to reach the main engine.
This period of time will be relatively long. The main engine will be in an oil-starved state for a period of time, and the main and auxiliary rotors will Dry friction can easily produce an open flame, which can ignite the air oil separator when sprayed into the oil and gas barrel.

The oil system design is defective or there is no temperature control valve

If the oil system design of the machine is defective or there is no temperature control valve. The air oil separator will be burned when the machine is started for a period of time or after maintenance. Due to defects in the oil circuit design of most air compressors, the oil after shutdown flows back into the oil and gas separation filter barrel. The inside of the cooler and the main engine are in a state of lack of oil and are filled with air. When starting the machine, the main engine needs to evacuate the air filled in it before the oil can enter.
Due to the long pipeline, the oil supply time will be too long. Causing the main engine to spray fire and cause the oil and gas separation filter element to burn. Some operators (mainly novices) did not add oil to the air inlet of the main unit or the oil filter when maintaining the machine. And then started the machine directly after the maintenance, causing malfunctions. This situation is basically the same as the failure situation that occurs when the machine is down for a long time.
There is another situation: a machine with a temperature control valve design but the temperature control valve is short-circuited for some reason. The bypass oil line is sealed, and the oil only flows through the cooler channel, please refer to the previous article.

Machine oil system failure

The main engine does not receive oil injection for cooling and lubrication. Dry friction is formed between the main and auxiliary rotors and the internal cavity and end surface. Sparks are easily generated under high-speed rotation. And enter the oil and gas barrel through the oil and gas common pipe to ignite the oil and gas separation filter material. This situation occurs in a very short period of time. The machine temperature sensor has a delay in sensing temperature. The high temperature trip protection has not responded in time, and the air oil separator has been burned. This problem usually occurs when the machine is started. After the star-delta conversion is completed, the machine starts loading after a few seconds delay.
Due to the failure of the main oil circuit. The engine oil has not yet reached the inside of the compression chamber of the main engine. The fully open intake valve sucks a large amount of air into the main engine. Since there is no oil cooling during compression. The main engine will make a sharp and harsh dry friction sound when running. Sparks generated by dry friction enter the oil and gas barrel, and the high-heat airflow rapidly expands under the action of the open flame. In about 10-20 seconds, the safety valve begins to release fire smoke.

Excessive static electricity causes sparks to burn air oil separators

You need to check the following aspects:
①The machine is not grounded or is grounded but has poor contact?
②Is there continuity between the oil barrel and the ground wire connected to the machine?
③ When installing a built-in air compressor filter and sealed with an asbestos pad. Checking whether the conductive nails on the oil separator barrel and the oil separator asbestos pad are in poor contact or completely insulated.
④Whether the air oil separators has an electrostatic conduction system or whether the electrostatic conduction system is normal.

How Does an Air Oil Separator Work?

Air compressor air oil separator operate on the principle of coalescence. As the compressed air-oil mixture enters the separator, it encounters specialized filter media or elements. These elements have a unique design that allows the oil droplets to coalesce and form larger oil droplets. These larger droplets then gravitate to the bottom of the separator, where they are collected and drained back into the compressor’s lubrication system. The now oil-free air continues its journey through the compressor and downstream applications.
