Hydraulic Fluids

At present, almost any hydraulic system contains in its composition control valves – devices that change both the direction and velocity of flow of hydraulic fluids, as well as for their badges and stop. They can be found in most small hydro systems, and on the bulky and powerful hydraulic presses. Manufacturers make distributors a variety of performances, but most often possible to meet control valves, designed for pressures up to 320 bar and have a hydraulic, electromagnetic, and electrohydraulic control. However, control valves are very sensitive to the position to apply the working fluid, so it is very important to exploit them according to specifications for purity oil, otherwise, they clogging and intensification of wear. If heavily soiled can even exit valves of the system. The most effective measures that can ensure proper cleanliness of operating fluids are flushing hydraulic systems and components before use, as well as filling the oil systems, not by pouring in tank, and a specially designed filtration and pumping devices, providing an almost perfect state of the pumped oil. Of course, any time, even the clean hydraulic fluid becomes more polluted, leading to an acceleration of aging, deteriorating its performance, which is why on manufactures recommend the use of a variety of industrial filters and filtration systems to ensure acceptable contamination class. Typically, these filters and systems are functioning in full flow mode, or proportional to cleaning.

Set them in the suction, discharge and pressure hydraulic line. If you would like to know more then you should visit Dropbox. Can often be see the combination of such filters. But not only all kinds of pollution pose a serious danger to the distributors. Corrosion processes can significantly harm the various elements of the control valve, so why it is important to minimize the effect of manifestations of these processes. This is achieved using oils with a reduced level of foam (in the bubbles accumulated air), as well as filters, removing time substances which promote the formation of foam. In addition, some filters can effectively remove moisture from and working fluids. The-art devices, although quite expensive, include filtration and dewatering aggregates, allowing not only to remove fluid from contamination, but also moisture. In addition, some models produce oil cooling.

In order to protect particularly sensitive hydraulic equipment normally install filters directly in front of such sites. Tendency to increase the purity requirements of hydraulic fluid only increased since the gaps in the hydraulic systems are constantly decreasing, the linear dimensions aggregates decrease, increasing the load on specific items. Therefore, the control valves are placing more stringent requirements to ensure sufficient purity fluids. And compliance with the purity hydraulic and lubricating oils will ensure the absence of multiple outages and repair costs caused by the poor condition of the working fluid.
