3. Reduce the internal pressure damage of the component system of the waste paper baler and reduce the power loss. Mainly to improve the pressure loss of the internal flow channel, it is necessary to use high-quality hydraulic components and integrated circuits and the casting of the flow channel to reduce the pressure loss of the pipeline and also reduce the oil leakage. To improve waste paper packaging, especially to ensure the cleanliness of hydraulic oil, prevent dirt from affecting the life and reliability of the hydraulic system, and the method of machine efficiency, and timely disposal and adjustment to avoid loss.
