The position of hydraulic oil filter in the system has a great influence on the effect of pollution control. In the hydraulic system, the filter can be installed in the suction circuit, pressure circuit and return circuit as required, or outside the main system to form a separate filter system.
Oil suction filter:
in order to prevent pollutants from entering the pump, the oil suction filter is generally installed in the oil suction port or oil suction pipeline. The filter at the oil suction port is immersed in the bottom of the oil tank, which is easily blocked by pollutants and difficult to maintain. Therefore, the screen type or line gap type filter without shell is generally used at the oil suction port.
Pressure pipeline filter: the filter installed in the pressure oil circuit is mainly used to protect the hydraulic components downstream of the pump.
As the main filter of the system, its filtering accuracy shall meet the requirements of the system for oil cleanliness.
The pressure difference of pressure oil filter is not very strict, so high precision filter can be selected.
The maximum allowable pressure difference is generally 0.35-0.5mpa, and the initial pressure difference is 0.07-0.14mpa.
The strength of the pressure oil filter should be able to withstand the maximum working pressure of the system, frequent pressure changes and pressure peaks.
Filter Media The media that HOSUN offer in the Products is the most efficient filtration media a hydraulic filter element can offer. Microglass` ability to capture 400 percent more particulate than Cellulose filter elements is why it is the best media choice for your hydraulic filter. The uniform shape and density of the glass fibers is what ensures the hydraulic filter`s 99.9% efficiency. Microglass filter elements are an excellent way to prevent unscheduled downtime and prolong the life of your hydraulic fluid.
Filter Seal Have you ever had to cold-start your equipment? If yes, then a Buna O-ring is an excellent choice for your hydraulic filter. Buna O-rings provide superior resistance to tear and abrasion during those cold-flow applications and they are the perfect ring when you decide to marry that cold-flow with petroleum products.
Buna O-rings are recommended for:General purpose sealing Petroleum oils and fluids Cold Water Silicone greases and oils Di-ester base lubricants (MIL-L-7808) Ethylene glycol base fluids (Hydrolubes) Operating temperature -45℉ to 225℉
