Hydraulic system suitable for loading machine and loading machine
The invention discloses a hydraulic system suitable for a loading machine and the loading machine. The hydraulic system comprises a hydraulic oil tank, a first hydraulic pump, a second hydraulic pump, a multi-way valve, a priority valve and a single connection valve. The first hydraulic pump is connected with the hydraulic oil tank; the second hydraulic pump is connected with the hydraulic oil tank; an oil inlet of the multi-way valve is connected with an oil outlet of the first hydraulic pump, and a working oil port of the multi-way valve is used for being connected with a working device; an oil inlet of the priority valve is connected with an oil outlet of the second hydraulic pump, and a CF port of the priority valve is used for being connected with an oil inlet of a steering gear; an oil inlet of the single-linkage valve is connected with an EF port of the priority valve, an oil return port of the single-linkage valve is connected with an oil inlet of the hydraulic oil tank or the multi-way valve, and a working oil port of the single-linkage valve is used for being connected with a third-linkage machine tool. The EF outlet of the priority valve is connected with the single valve, the oil return opening of the single valve converges to the oil inlet of the multi-way valve, the working condition that a third machine tool needs small flow is met under the condition that no extra pump is added, and excessive energy loss is avoided.
本发明公开了一种适用于装载机的液压系统及装载机，所述液压系统包括液压油箱、第一液压泵、第二液压泵、多路阀、优先阀和单联阀；第一液压泵与所述液压油箱相连；第二液压泵与所述液压油箱相连；多路阀的进油口与所述第一液压泵的出油口相连，其工作油口用于与工作装置相连；优先阀的进油口与所述第二液压泵的出油口相连，其CF口用于与转向器的进油口相连；单联阀的进油口与所述优先阀的EF口相连，其回油口与所述液压油箱或多路阀的进油口相连，其工作油口用于与第三联机具相连。本发明将优先阀EF出口连接单联阀，单联阀的回油口合流至多路阀的进油口，在不额外增加泵的情况下满足第三联机具需要小流量的工况，避免过大的能量损失。
