Movable device for comprehensive water pump series-parallel connection experiment

Abstract

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.

Description

Technical field [0001] The invention relates to a mobile water pump series-parallel comprehensive experimental device, which belongs to the technical field of hydraulic experimental devices. Background technique [0002] Water pump series and parallel experiments and water pump characteristic curve experiments are one of the important teaching contents in the courses of fluid mechanics, hydraulics, water pumps and water pumping stations in the fields of environment, water supply and drainage, construction, civil engineering, machinery, mining, transportation, etc. However, the traditional water pump series and parallel experimental devices have disadvantages such as large equipment volume, large area occupied by the laboratory, fixed on the ground, and occupied laboratory space. Due to the high cost, the number of sets of experimental devices configured is generally small, which is difficult to meet the needs of experimental teaching and seriously affects the progress of tea...
