How to choose the precision of the vacuum oil filter
Vacuum oil filter professional manufacturer, dual energy oil filter company is committed to providing customers with high quality and efficient vacuum oil filter, reasonable price, good service. We take the lead in achieving the quality of the vacuum filter machine sold, warranty For ten years, free to install, debug equipment and train operators on site.
The choice of filtration accuracy of vacuum oil filter is mainly affected by two factors. The need for oil. For example, insulating oils must pass high-precision filtration to achieve high insulation values, while large modulus gears require much more impurities. The viscosity of the oil. High viscosity oils cannot pass through the fine mesh and require reduced precision.
If the vacuum oil filter uses a precision filter on one side to emphasize the cleanliness of the oil, it will increase the operating cost of the oil filter. because:
(1) Increase the axial pressure so that the oil can pass through the filter faster, but it will often crush the filter.
(2) The filter element is often clogged, requiring frequent cleaning or even replacement of the filter element.
(3) 46# below lubricating oil, turbine oil, choose 10 ~ 20μm.
(4) The internal combustion engine oil and gear oil are selected to be 20 to 50 μm.
(5) Add a preheating tank to increase the temperature and reduce the viscosity.
(6) Insulating oil, choose 1~5μm.
