When the hydraulic system is working, the oil level in the oil tank sometimes rises or falls. When it rises, air is discharged from the inside out, and when it falls, air is sucked in from the outside in.
To purify the oil in the fuel tank, install an air filter vertically on the fuel tank cover plate to filter the air sucked in; At the same time, the air filter is also an oil injection port, and the newly injected working oil must be filtered before entering the oil tank, thereby filtering out the dirt particles in the oil.
In hydraulic systems, purification work is a crucial step. The air filter can keep the oil in the mailbox clean, prevent dirt particles from entering the oil tank from the outside, and prolong the working cycle and service life of the oil and components, thereby ensuring the normal operation of the hydraulic system.
In addition, during the operation of the hydraulic system, the air filter can maintain a balance between the pressure inside the oil tank and atmospheric pressure to avoid possible pump cavitation.
