Pump truck hydraulic system and pump truck
The invention discloses a pump truck hydraulic system and a pump truck. The pump truck comprises a pump truck hydraulic system. The pump truck hydraulic system comprises a boom pump, a pumping pump and a control valve group, is communicated with a boom liquid supply pipeline and a pumping liquid supply pipeline and can be switched between the pumping liquid supply state and the boom liquid supply state, wherein the control valve group enables the boom liquid supply pipeline to be communicated with the pumping liquid supply pipeline in one way in the pumping liquid supply state to allow the boom pump to supply hydraulic liquid to the pumping system; in the boom liquid supply state, the control valve group enables the pumping liquid supply pipeline to be communicated with the boom liquid supply pipeline in one way to allow the pumping pump to provide hydraulic liquid for the boom system. The pump truck hydraulic system achieves the following function that two pumps can supply liquid to one system together on the same pump truck and can also conduct liquid supply work independently. Compared with the prior art, the energy consumption can be reduced to the largest extent, and missed working time caused by damage to the single pump is avoided.
