(Summary description)Most compressed air lubricators work according to the principle of Venturi. There is a slight pressure difference △p (pressure drop) between the front end of the air constriction and the smallest section of the constriction, and the lubricating oil in the container is therefore The pressure difference is attracted to the constriction, and then mixed with the passing airflow to flow out. The compressed air lubricator will only take effect when the airflow reaches a relatively high speed.

Information

Most compressed air lubricators work according to the principle of Venturi. There is a slight pressure difference △p (pressure drop) between the front end of the air constriction and the smallest section of the constriction, and the lubricating oil in the container is therefore The pressure difference is attracted to the constriction, and then mixed with the passing airflow to flow out. The compressed air lubricator will only take effect when the airflow reaches a relatively high speed.

When the air consumption is very small, the speed of the air flow is not enough to produce a proper pressure drop at the constriction, and the lubricating oil cannot be drawn from the nozzle. The lubricating oil cannot be sucked from the nozzle. , The use of air lubricator must pay special attention to the maximum and minimum flow values ​​specified by the manufacturer.

Air lubricators have various structural forms. According to the size of the oil mist particles, there are two types: ordinary lubricator (primary atomization) and micro-mist lubricator (secondary atomization). Micro-mist lubricator After the atomized oil mist particles, only the oil mist particles with a diameter of less than 2m are transported out.

According to the throttling method, it can be divided into two types: fixed throttling and automatic variable throttling. The concentration of oil mist output by the former changes with the change of air flow, while the concentration of oil mist output by the latter remains basically constant and does not change with the change of air flow.
