Return filter: set on the oil return pipeline of the system. Its function is to capture the pollutants generated or invaded in the system before returning to the oil tank. Therefore, it is the most effective and important filter to control the pollution concentration of the system. Although it is a low-pressure pipeline, pulsation or pressure impact will also occur according to the operation condition of the transmission device, so the material and strength of the components should be fully considered.

Principle of foaming machine of pneumatic mold base and function of filter

The basic principle of foaming machine is to introduce air into foaming agent solution. The change of various models lies in the different ways of introducing gas, so the effect is also different. There are two necessary factors for the formation of foam, one is blowing agent solution, the other is air, and the two are dispensable for the two. Without foaming agent solution, the liquid film surrounding the gas will not form and there will be no bubbles. Without gas and foaming agent solution alone, bubbles cannot be formed. In the bubble forming system, the foaming agent solution is a dispersing medium, the gas is dispersed phase, and the gas dispersed in the liquid can form bubbles, and then bubbles formed by numerous bubbles.
