The metal mesh of filter elements of the Transformer Oil Purifier maintains the original shape of the corrugation to prevent bending and provide the filter material. The service life of the filter element mainly depends on materials, design, manufacture and using. After the Transformer Oil Purifier works for a period of time, some impurities will accumulate in the filters, which not only cannot guarantee the oil filter treatment effect, but also reduces the working efficiency of the oil filter. Following is introductions for why the flow rate will reduce after Vacuum Transformer Oil Purification Machine working a long time.

1. There are too many impurities and the filter element are blocked. The Vacuum Transformer Oil Purifier can remove water and impurities. The function of filtering impurities is realized by strong magnetic adsorption and filter element interception. The strong magnetic mainly adsorbs the metal of the iron element, and other impurities mainly pass intercepts of filter element, once the intercepted impurities are too much and the filter element is blocked, which will reduce the oil volumes flowing through filters, so it reduce the flow rate of Vacuum Transformer Oil Purifier.

2. The heater is damaged, which causes the viscosity of the oil to increase, the fluidity becomes poor, and the oil filtration will slow down; the heating system of the general Vacuum Oil Purifier has two functions: heating the oil to increase the fluidity and increase the oil temperature to achieve vacuum evaporation.

3. The oil grade is very high, and the Vacuum Oil Purifier that does not filter high-viscosity oil is not considered. Choosing the wrong equipment will also cause the filtration efficiency to be too slow. Generally, Vacuum Oil Purifier for Transformer must be done with double pumps, otherwise the pumping power is not enough.

How can we solve the problem of flow rate reducing to maintain the efficiency and good performance of the Vacuum Transformer Oil Purification Machine?

1. Cleaning or replacing of the filter element of the Vacuum Oil Purifier. If materials is the stainless steel wire mesh, when cleaning the filter element. Please don’t damage or deform the mesh. If mesh is damaged or deformed, please replaced. If the materials are cotton or fibres, the filter elements only can be changed.

2. Although the Vacuum Transformer Oil Purification Machine is used to separate impurities in the oil, long-term use will accumulate impurities, which will affect the quality of the oil, reduce the working efficiency of the Transformer Oil Purifier, and reduce the service life and oil consumption and the lifetime. So Vacuum Transformer Oil Purification Machine should be carefully maintained to avoid unnecessary damage and waste.
