1. The double pump and double circuit open hydraulic system is adopted. The main pump oil circuit and the S valve swing oil circuit are independent of each other, making the system simpler and more practical. The reliability is higher.
2. The main pump oil return direction is controlled by the main control valve external control pilot decompression control, which avoids the impact of the reversal and makes the main pump oil return direction more reliable and stable.
3. The pumping hydraulic system has safety overflow protection. At the same time, when the main pumping system is over-pressured, the oil pump pressure is cut off automatically and the main pump is protected in multiple stages.
4. Adopt oil-absorption filtering technology to prevent foreign objects from entering the hydraulic system, further improving the reliability of the hydraulic system and the life of each component.
Second, the pumping oil circuit uses valve block mode for high and low pressure switching, convenient and reliable.
Third, the high-power forced air-cooled radiator enables the oil temperature to be effectively controlled and ensures the normal operation of the host hydraulic system.
Fourth, the hydraulic pipeline adopts conical seal or imported rectangular seal, and the pipeline joint is sealed reliably.
Fifth, the electrical system uses a programmable controller (PLC), which is intelligent, integrated and humanized. The main electrical components are selected from Japan's Mitsubishi, Omron, and French Schneider to ensure high reliability of the system.
Sixth, the hopper, S valve and other key force components, using computer programs to simulate the structural state of stress, stress concentration of the situation; the designed hopper, S valve structure of good steel, good processability, to avoid Deformation of the hopper and shaft breakage of the S valve during high-level transportation of similar products.
