Intercept large particles such as metal chips, dust, and gel-like impurities to prevent them from entering the pump and causing internal wear, jamming, or cavitation. At the same time, it also prevents impurities from scratching the inner wall of the oil cylinder and blocking the valve core, thereby reducing the risks of leakage and malfunction.
2. Ensure system performance
Maintain the cleanliness and smoothness of the oil, reduce internal friction, ensure smooth oil intake by the pump, improve the response accuracy of actions such as lifting, tilting, etc., and avoid insufficient power or sluggish movements caused by blocked oil passages.
