The invention discloses a hydraulic system with excellent heat dissipation performance and an emergency drainage vehicle. The hydraulic system comprises a hydraulic oil tank; a variable pump; an engine; a reversing valve; the inlet of the multi-way reversing valve is communicated with the first outlet of the reversing valve, and the outlet of the multi-way reversing valve is communicated with the inlet of each actuating mechanism; an outlet of each executing mechanism is communicated with an inlet of the radiator through a multi-way reversing valve, and an outlet of the radiator is communicated with the hydraulic oil tank; the oil return pipeline is arranged in the drainage pipe, a second outlet of the reversing valve is communicated with an inlet of the execution element, an outlet of the execution element is communicated with one end of the oil return pipeline, and the other end of the oil return pipeline is communicated with an inlet of the radiator; an inlet of the switch valve is communicated with an outlet of the execution element, and an outlet of the switch valve is communicated with the hydraulic oil tank. The temperature of the hydraulic oil can be in the optimal working temperature range, and various hydraulic system problems caused by the fact that the temperature of the hydraulic oil is too high or too low are avoided.

    本发明公开了一种优良散热性的液压系统及应急排水车,液压系统包括:液压油箱;变量泵;发动机;换向阀;多路换向阀,多路换向阀的进口与换向阀的第一出口连通,多路换向阀的出口与各执行机构的进口连通;散热器,各执行机构的出口通过多路换向阀与散热器的进口连通,散热器的出口与液压油箱连通;回油管路,回油管路设于排水管内,换向阀的第二出口与执行元件的进口连通,执行元件的出口与回油管路的一端连通,回油管路的另一端与散热器的进口连通;开关阀,开关阀的进口与执行元件的出口连通,开关阀的出口与液压油箱连通。本发明能够使液压油温度能够处于最佳工作温度范围,避免出现因液压油温度过高或过低造成的各种液压系统问题。
