Information

The size of the selected air lubricator should not be too small or too large. The correct selection of the air lubricator model and size depends on the air consumption of the cylinder, because before the lubricator starts to fill the oil, all the lubricators are required to be under a very small volume flow. , That is to say, if the size of the oil injector is too large, it may be invalid under certain conditions. If it is too small, the possible air leakage will cause the oil of the lubricator to be consumed during the no-load cycle. The general principle is that a cylinder with a heat-resistant seal does not necessarily need to provide compressed air containing oil mist. Because this will flush out the original special grease.

The pressure of the compressed air is not high, so the pressure loss of each link must be strictly controlled, that is, the flow rate. At the same time, attention should be paid to the "fogging flow" index. But it can't play the role of lubricating element. The oil mist particle size of ordinary lubricator is 20~35m, so its transportation distance is limited. Therefore, the lubricator should be as close as possible to the reversing valve, and the distance from the valve cannot exceed 5m. The pipeline volume between the air lubricator and the reversing valve should be less than 80% of the cylinder stroke volume. When there is a throttling device in the pipeline, the above-mentioned volume ratio needs to be halved.

During the working process, the lubricating oil level in the oil cup should always be kept between the upper and lower limit scales of the oil cup. Too low oil level will cause the oil suction pipe to expose the liquid surface and not suck the oil, and too high liquid level will cause airflow. Direct contact with oil will take away too much lubricating oil and cause oil deposits in pipelines.
