The invention relates to a movable device for a comprehensive water pump series-parallel connection experiment, belonging to the technical field of a hydraulic experiment device. The movable device comprises a water pump system, a control box, a connection pipeline and a switchover valve; an experiment system is fixedly arranged on a movable frame with wheels; a water pump, a water tank, a flow meter, a control box and a pipeline of the experiment system are fixedly arranged on a bracket and a rung of the movable frame; the water pump system comprises a water pump, a temperature sensor, an inlet valve, a vacuum meter, a pressure meter, a Venturi flow meter, a flow adjusting valve, a rotor flow meter, a water input pipe and a water transmission pipe; the water input pipe is connected with the water pump and the water tank; the water input pipe is connected with the water pump and a general water output pipe; the outlet of the general water output pipe is connected with the water tank; and the water transmission pipes of two sets of the water pump systems are connected in series or parallel through the switchover valve so as to obtain a feature curve of the water pump. The movable device provided by the invention has the advantages that: the whole device can be moved; the water is convenient to discharge and the use ratio of a laboratory is improved without building a special laboratory; and the connection relation among the components can be directly displayed; and therefore, the movable device is good for teaching.
