An overview of industrial oil purification
If you own an industrial establishment, you probably have an idea about the importance of maintenance of various machines. Mechanical structures require to be taken care of on a regular basis in order to operate in a smooth fashion. Machines like turbines and compressors that include oil flow require special attention. That’s the reason why you have to conduct oil flushing every once in a while. There are several companies that manufacture different industrial oil purification systems all over the world in order to carry out this task properly. An overview of these systems is given below for your better understanding.
An industrial oil purification system is mounted within a frame made of a strong metal. There is a vacuum vessel, vacuum pump, pipeline, unitized controller, gear pump, fine cartridge filter and a primary cartridge filter. The vacuum vessel is completely heat insulated from the outside and has a cylindrical chamber that is placed within a casing. In addition to this, there are a few electrical heaters. They are used to heat the oil that is processed within the casing. The vessel is connected with the outside atmosphere through a throttle and a moisture separating filter. The throttle is used to regulate the exhaustion rate inside the chamber.
During the oil flushing process, gear pumps are used. They are attached with a bypass line having safety valves and taps on it. The driving mechanism of every one of the pumps has a three-phase asynchronous motor along with a cage rotor. The pumps are used in order to exhaust the chamber. There are different modes of operation within the system. These include the filtration mode, thermal vacuum purification mode and degasification mode.
In the filtration mode, oil travels from the mesh filter and the input valve and then gets sucked through a gear pump. Then it goes from the primary cartridge filter to the final, processed oil vessel. This mode is the simplest yet it delivers the finest results.
The thermal vacuum purification mode works upon the same basic principle but when it gets to the processed oil vessel, it is heated up to 60 degrees Celsius using electrical heaters. Then the oil moves towards the vacuum vessel sparger. The whole process is carried out in a vacuum that is created using a vacuum pump. The exhaustion rate within the vessel gets regulated using throttle while it is controlled using a vacuometer. The air transfers to the oil vessel from a moisture separator. Both the vapors as well as the gases are carried away from the surface of the oil while the oil gets dried up.
The degasification mode is considered to be the most efficient mode. Just like the thermal vacuum purification mode, it works on the same basic principle. After the oil is transferred to the processed oil chamber, it is heated and directed towards sparger, which separates the oil from the gases. The separated gases are then taken out through an oil separator and are disposed of to the atmosphere.
