How to clean and maintain the filter element of vacuum oil filter?
The filter element of the vacuum oil filter is used to keep the hydraulic oil clean in the oil filter. How can the filter element of the vacuum oil filter ensure the cleanliness of the oil in the long run? The key also depends on our correct use!
We should correctly choose the filter element of vacuum oil filter, because the model between the filter element and the equipment is matching, if the improper selection will affect the filtering effect.
The filter element of the vacuum oil filter needs to be cleaned and replaced in a timely manner, because impurities in the oil concentrate on the filter element when the oil is purified. If it is not clear for a long time, the oil filtration speed will slow down and the oil quality will not be clean enough.
In the use process can not increase the axial pressure, if so the oil can pass through the filter screen quickly, but often because of this will crush the filter element, affecting the cleanliness of hydraulic oil.
In order to ensure the filter element of vacuum oil filter is clean, we must clean the filter element of vacuum oil filter in time. The method is described as follows:
1. Before cleaning the vacuum oil filter, stop the operation of the oil filter, close the oil inlet and outlet pipelines, and turn off the power switch.
2, open the oil valve, drain all the oil in the filter until the end of the oil flow (you can open the air valve to speed up the oil discharge).
3. Open the filter cover and take out the filter element after placing.
4. Take out the filter element of vacuum oil filter, put it into the oil pan with kerosene, soak it for 30 minutes, clean it, and blow it with air.
5. Remove the sediment on the surface of the vacuum oil filter with a brush, and then wipe the filter clean with a cloth.
6. Then install the filter element and lock the filter bolt. Only after cleaning can it be put into use.
Hydraulic system filter element classification
1. Oil absorption filter element
The oil filter element is installed in the oil inlet pipe to prevent the coarse particles from damaging the hydraulic pump. The filter element of oil absorption filter usually adopts the structural form of filter paper and metal net. In order to prevent cavitation in the pump, the resistance of the filter during the filtration process should not exceed the specified value.
2. High pressure filter element
The high pressure filter element is installed directly in the high pressure pipeline and ensures that hydraulic oil is supplied to one or more working parts to meet the working requirements as required. High pressure filters usually use a synthetic or semi-synthetic filter.
3. Return oil filter element
The oil return filter element is installed in the back flow pipeline of the hydraulic components to ensure the long service life of the back flow filter before the hydraulic oil flows back to the oil tank and the purity of the oil in the oil tank. The filter medium of oil return filter is synthetic fiber or natural fiber.
4. Replace imported filter elements
PALL, HYDAC, Parker, MPFILTRI, INGERSOLLRAND, DONALDSON, SULLAIR, ATLASCOPCO, JOHNDEERE, MANNFILTER, CAT, BALDWIN, and so on. The interchangeable filter element made of imported glass fiber is designed and developed for industrial oil filtration system. In order to meet the strict requirements of the system on cleanliness, the filter element with high precision is provided to the user, and the filter precision can reach 1 micron, so as to meet the requirements of the system on particle filtration.
5. Water treatment filter element
Water filter element is mainly used in security filtering, sea water treatment, power plant condensate water filtering, biological medicine industry solvent, drinking water, edible oil and other liquid filtering. It has the advantages of stable filtration performance and long service life.
6. Coal mine filter element
Filters and filter elements used in coal mine are widely used in hydraulic support control systems at home and abroad. Applicable to DBT, JOY and other imported hydraulic support and zheng coal, north coal, pingdingshan coal and other domestic hydraulic support. It can be divided into: coal mining hydraulic filter element, hydraulic pump station filter element, hydraulic pump station high pressure filter element, coal mine equipment vehicle oil filter element, coal mine equipment vehicle air filter element, hydraulic support valve filter element, hydraulic support backwash filter element and other types.
