The modern hydraulic equipment of high accuracy class challenges the cleaning of hydraulic machines and hydraulic fluids clean. Since the filter effectively protects the hydraulic element, located directly behind it, other elements have only partial protection. Therefore, the hydraulic systems used various combinations of filters that are installed on different lines of hydraulic systems. Apply 3 major how to install filters in hydraulic systems: in suction, pressure or drain line. Depending on how the different design and model filters.
Full-pressure filters provide filters. Since these filters have a high metal content and the relatively high cost, generally they are used for particularly sensitive to contamination by elements of the hydraulic system. Pollution, not arrested pressurized filter, catch drain filters, providing a thin fluid filtration .. Usually they are installed on the tank emergents. The standard features of drain filters are: – availability of relief valve – high performance (expense) – compact drain filter can be incorporated into the tanks, but this may create increased pressure in the drain line buttress, which is undesirable.
Much more often they are inserted into the drain line, causing the filter does not feel pressure and does not create additional resistance to the pump inlet, which is important to prevent cavitation at the pump. From returning to fluid tank mounted in such a way filter retains all dirt. Suction filters allow for full-flow filtration of hydraulic fluid that is injected into the system pumps. These filters trap hit in the big pumps mechanical particles, protecting the latter from wear and dirt. Thus, the filters need to choose on the basis of pressure, flow and filtering capacity of the working fluid. K quality include filters that have the following qualities: high-pressure fracture, long life, high dirt holding capacity, high stability of the beta coefficient in a wide range of pressure drop low pressure drop. This allows you to securely protect the sites and reduce equipment downtime hydraulic systems.
