How to choose the right filter?

Do you know how to clean the hydraulic oil filter ?

Hydraulic oil filter elements are generally used in hydraulic stations and hydraulic systems, and should be cleaned regularly, because the hydraulic oil filter element has been blocked by the stains in the hydraulic oil after a period of use, so that the filtering effect cannot be achieved. *Hydraulic oil filter element prolongs the life, Leen filter element editor teaches you how to clean the hydraulic oil filter element:

If the hydraulic oil filter element is made of metal mesh or copper mesh, you can soak it in kerosene for a period of time, and then blow it with an electric wind, so that the blockage and stains can be cleaned up.

If the hydraulic oil filter element is made of glass fiber or filter paper, it cannot be cleaned, and cleaning will not work. In this case, a new hydraulic oil filter element needs to be replaced.

If it is an oil-absorbing filter element, there are built-in filter elements and an external filter element. The built-in filter must pump the oil below the filter element before replacing it; the external one directly removes the bolts on the outside of the filter, and the filter element comes out. At the same time, the oil is locked by the one-way valve and will not flow out, which is very convenient.

hydraulic oil purification with big flow rate

The hydraulic filter element is used in the hydraulic system to filter out the particulate debris and rubber impurities in the system, and the cleanliness of the hydraulic system. The material of hydraulic oil filter element mainly includes paper filter element, chemical fiber filter element (glass fiber metal fiber sintered felt polypropylene fiber polyester fiber) mesh filter element (stainless steel mesh) line gap filter element.

Hydraulic oil filter element is suitable for filtering strong acid, strong alkali and organic solvent. The filter membrane is folded depth filtration, with large membrane filtration area, low pressure difference, strong dirt holding capacity and long service life. There are various models and specifications to choose from.

Hydraulic oil filter

When choosing a hydraulic oil filter element, the following points should be paid attention to:

1. Filtration accuracy of hydraulic oil filter element

Each hydraulic system must consider the purity of the hydraulic oil, and the filtration accuracy is the first consideration.

Second, the strength of the hydraulic oil filter

The second is strength and corrosion resistance. The strength of a good hydraulic oil filter element must meet the standard. The hydraulic oil filter element of the pipeline must be able to withstand the high pressure downstream of the pump. The oil suction filter element must be able to withstand the pressure without affecting the oil flow. No deformation, the mesh will not change the diameter and cause the accuracy to change.

3. Precautions for installation of hydraulic oil filter element

The installation position should be considered, and the function and accuracy of the hydraulic oil filter element in different positions are also different.
