The working principle of the lubrication system of vertical machining center!

Lubrication system of Vertical Machining Center. 

To put it simply, the lubrication system of the vertical machining center is to mix the separately supplied lubricating oil and compressed air to form a turbulent oil-gas mixed flow and send it to the spindle or other lubrication parts of the machining center.

working principle. 

Using the flow of compressed air in the pipe to drive the continuous flow of lubricating oil along the inner wall of the pipe, the oil and gas are mixed and transported to the spindle of the machining center and other parts that need to be lubricated. 

Dry compressed air is continuously supplied at a constant pressure (5-8BAR), while lubricating oil is supplied according to the amount of oil consumed in spindle lubrication, screw lubrication or other parts. 

Therefore, each lubrication loop must use a separate miniature oil pump as the power source for oil transportation. after coming out of the pump, the oil must first enter the oil-gas mixing valve. In the oil-gas mixing valve, the flowing compressed air blows the oil into small oil droplets and attaches to the pipe wall to form an oil film. The oil film flows along the pipe wall with the direction of the air flow. In the process of flow, the thickness of the oil film is gradually thinned, but it is not condensed.
