Installed at the oil suction port of the oil pump The filter is required to have a large flow capacity and small resistance, and its flow rate should be more than twice the flow rate of the oil pump to prevent cavitation. It is mainly used to protect the hydraulic pump, but the wear products generated in the hydraulic pump will still enter the system. Generally, filters with lower filtering accuracy are used. 2. Installed at the oil outlet of the oil pump This filter should be able to withstand the working pressure and impact pressure on the oil circuit; In order to prevent the hydraulic pump from being overloaded or the filter element from being damaged when the filter is clogged, it is advisable to connect a bypass valve or an indication device in series on the pressure oil circuit. This method is commonly used in systems with high filtering accuracy requirements and in front of servo valves and speed regulating valves to ensure their normal operation. 3. Installed on the oil return road We call it a return oil filter, which can filter out metal chips and rubber particles generated after the wear of hydraulic components, and protect the cleanliness of the fluid flowing back to the tank. Il est permis d'utiliser des filtres avec une résistance et une rigidité inférieures de l'élément filtrant ; Afin d'éviter que la pression du système n'augmente en raison du colmatage de l'élément filtrant, il est nécessaire de connecter le filtre en parallèle avec la vanne unidirectionnelle pour agir comme une vanne de dérivation. 4. Filtration de dérivation indépendante Dans le système hydraulique des grosses machines, un système de filtrage indépendant composé de pompes hydrauliques et de filtres peut être spécialement installé pour éliminer en continu les impuretés du système et améliorer la propreté de l'huile.
