Daily use (maintenance) of filters Misunderstandings about filters

Myth 1: A filter with a bypass valve cannot be cleaned or replaced for a long time after the filter element is clogged Many users will think that the bypass valve of the filter and the system The safety valve has the same function: after the filter element is clogged, the bypass valve opens and the system oil passes through at full flow without affecting the system. This is a wrong understanding. When the bypass valve of the filter is opened, the pollutants (filtered pollution particles) blocked by the filter element will re-enter the system through the bypass valve. At this time, the pollution concentration of the local oil is high, which will have a negative impact on the hydraulic components. If the damage is serious, previous pollution control will be meaningless. Unless the system requires very high continuity of operation, choose a transition device without a bypass valve. Even if a filter with a bypass valve is selected, when the pollution in the filter blocks the signal from the transmitter, the filter element must be cleaned or replaced in time. This is the way to ensure the safe and reliable operation of the system.
