Hydraulic fluid, as the lifeblood of a hydraulic system, is an indispensable core element that drives the operation of the entire system. Without a sufficient volume of high-quality hydraulic fluid in any hydraulic system, the proper functioning of the system is impossible. However, while hydraulic fluids play a key role, they are also at risk of contamination, which is particularly important to address. In the complex environment of a hydraulic system, the fluid will inevitably be mixed with a variety of impurities. The source of these impurities are widely varied, both the initial stage of the system on the legacy of the “natives”, such as iron filings, welding slag, cast sand, paint skin and cleaning process failed to remove the cotton debris, etc.; but also from the external environment, “invasion of” the “uninvited guests”. “uninvited guests”, they may sneak in through the oil inlet, the tiny gap of the dust ring, or with the air and transportation equipment into the fluid, in the face of these potential ‘polluters’, hydraulic filtration tanks In the face of these potential “contaminants”, hydraulic filtration tanks become a strong line of defense to guard the cleanliness of the hydraulic fluid. Its core mission is to filter out all kinds of impurities in the fluid, strictly control the cleanliness of the fluid, thus effectively reducing the pollutants entering the system and ensuring that the hydraulic system can run smoothly and efficiently.
Hydraulic components vary in their sensitivity to impurities in the oil, and as a result, the oil filtration accuracy requirements vary significantly from one hydraulic system to another. Variations in system pressure can likewise affect the need for filtration accuracy. When selecting hydraulic filtration tanks, the specific needs of the hydraulic system must be fully considered:
For general hydraulic systems, hydraulic filtration tanks should be selected to ensure that the particle size of the impurities in the fluid is smaller than the gap size of the hydraulic components, in order to prevent damage to the components caused by impurities; for the follow-on hydraulic system, due to its extremely high requirements for fluid cleanliness, so the selection of hydraulic filtration tanks should be extremely high filtration accuracy. For the follow-on hydraulic system, because of its extremely high requirements for fluid cleanliness, hydraulic filtration tanks with high filtration precision should be selected.
In the selection of hydraulic filtration tanks, also need to follow the following basic principles:
(1) have enough filtration precision, can effectively block a certain size of impurity particles, to ensure the cleanliness of the fluid.
Excellent oil performance, that is, when the oil through the hydraulic filtration tanks, under the conditions of a certain pressure drop, the unit filtration area can pass through a large amount of oil to meet the system requirements for oil flow.
(2) The filtration material should have strong mechanical strength and be able to withstand the pressure of the oil without being easily damaged, so as to ensure the long-term stable operation of hydraulic filtration tanks. In a certain temperature range, hydraulic filtration tanks should have good corrosion resistance and enough life to adapt to the use of different working conditions.
(3) Convenient cleaning and maintenance, easy to replace the filter material, in order to reduce maintenance costs and improve work efficiency.
Hydraulic oil contamination should not be ignored, and hydraulic filtration tanks as a key tool to solve this problem, its selection and use must strictly follow the actual needs of the hydraulic system and technical specifications. Through the scientific and reasonable selection of hydraulic filtration tanks, we can effectively protect the normal operation of the hydraulic system, extend the service life of the equipment and improve production efficiency.
