Mist Lubricator

A mist lubricator is a device used to dispense oil lubricant to bearings. The oil lubricant is an air-borne lubricant that comes in the form of oil mist. The oil mist can be spread evenly into the working environment so that a better result of lubrication can be achieved. Since a mist lubricator has close control of the oil mist lubricant to bearings, it is applicable to offer continuous and adequate lubrication to the bearings without excessively lubricating the parts. The mist lubricator is also known as an oil mist lubricator. Besides bearings, the oil mist lubricators are also applied for the lubrication of other types of rolling elements in machinery.
 

General Features of Oil Mist Lubricator

An oil mist lubricator is a fully automated machine that is designed to apportion a proper amount of oil mist to the surface of bearings. Inside the machine, there is an air filtration system, a pressure control system, and an oil atomization system. The air filtration system makes sure that no impurities or unwanted matters enter the oil mist and later spread onto the bearings. The pressure control system is responsible for dispensing the proper amount of oil mist into the working environment. The oil atomization system turns liquid oil into oil mist.

The use of oil mist lubricators brings about advantages both financially and environmentally. If the lubrication of machinery is done properly, the equipment failures can be minimized which further leads to the reduction of operating costs and maintenance costs. The oil consumption is controlled by the lubricator itself; therefore the excessive distribution of oil lubricates oil is avoided. With these features, the lubricator has become a necessity for industrial machinery.
 

Pressure Control System

The pressure control system incorporates a set of units including a pressure gauge, the air valve, electric wire conduit box, and pressurized reservoirs. The pressure gauge and the pressurized reservoirs inside the pressure control system determine the dispensing rate and pressure of the oil mist that enters the working environment. The dispensing of the mist is controlled by the air valve. The electric wire box controls the function of the system. The mist output can be adjusted in real-time according to the working condition of the machinery.
 

Oil Atomization System

The oil atomization system is responsible for atomizing the liquid oil and turning it into fine droplets. When the oil lubricant is atomized, it will be carried away by an air stream and distributed into the bearings through the tubing inside the lubricator. The air stream not only serves as the agent to drive the oil particles out into the bearings but also as the coolant to lower the working temperature of the bearings. The tubing inside the system can be either rigid or flexible based on the end application.
 

Air Filtration System

The air filtration system lies at the compressed air inlet. As soon as an air stream enters the mist lubricator, the air filtration system functions immediately to filter out the particles or impurities in the air. Though the matters in the air are very fine, they can still affect the performance of the rolling elements in a machine. The impurities can potentially lead to abrasion and wear which shorten the longevity of the bearings and the moving components in the machinery. The air filtration system can reduce the risk to the most extent.
 

Maintenance of Oil Mist Lubricator

The maintenance of an oil mist lubricator is not too complicated. The first thing to check is the pressurized oil reservoirs. Since the mist lubricator is a unit that is constantly working, the oil is consumed rapidly. It is recommended to check the oil level on a daily basis and refill the reservoir as frequently as necessary. The other parts to check are the filters in the filtration system. The filtration ability declines through use. To avoid the deficiency of filtration, the filters should be replaced periodically. Last but not least, the tubing inside the machine should also be checked. There may be water or dirt accumulation at the valves or tubing over time. The function and performance of the mist lubricator can be sustained if the maintenance is done properly and timely.
