Hydraulic oil filterIt is mainly composed of a filter element (or mesh) and a housing (or skeleton). The flow area of the oil is composed of countless tiny gaps or small holes on the filter element. Therefore, when the size of impurities mixed into the oil is larger than these tiny gaps or small holes, they are blocked from being filtered out of the oil. Due to the different requirements of different hydraulic systems, it is impossible to filter impurities mixed into the oil.

But when impurities such as water rust, casting sand, welding slag, iron filings, coatings, paint skins, and cotton yarn shavings enter the hydraulic system from the outside, they will cause damage everywhere with the circulation of hydraulic oil, seriously affecting the normal operation of the hydraulic system. Make small gaps (measured in micrometers) between relatively moving parts in hydraulic components, as well as throttle holes and gaps stuck or blocked; Damaging the oil film between relative moving parts, scratching the gap surface, increasing internal leakage, reducing efficiency, increasing heat generation, intensifying the chemical reaction of the oil, and causing the oil to deteriorate. According to production statistics, more than 75% of hydraulic system failures are caused by impurities mixed in hydraulic oil. Therefore, maintaining the cleanliness of the oil and preventing oil contamination are important for hydraulic systems. Besides these, choose what suits you bestHydraulic oil filterIt's also very important!

How to choose?

(1) When selecting, the type of filter can be chosen based on the characteristics of various filters mentioned above, combined with the requirements of typical hydraulic components and systems for pollution levels or filtration accuracy, as well as the working pressure, oil temperature, and oil viscosity of the system.

(2) To have sufficient flow capacity, flow capacity refers to the flow rate allowed to pass through the filter under a certain pressure drop. It should be selected based on the installation position of the filter in the system and the filter sample.

(3) It should have a certain mechanical strength and not be damaged by hydraulic pressure.

(4) For hydraulic systems that cannot be shut down, a switchable structure filter must be selected.Hydraulic oil filterYou can replace the filter element without stopping the machine.
