Experimental device for hydrological axial flow pump

Abstract

The invention provides an experimental device for a hydrological axial flow pump. The experimental device for the hydrological axial flow pump comprises a workbench and a solenoid valve. The left sideof the top end face of the workbench is fixedly provided with a circulating water tank. The left side, adjacent to an edge position, of the top end face of the workbench is fixedly provided with a control device, and the control device comprises a microcontroller and a touch-type display. The other end of a first transmitting pipe is fixedly communicated with the rear side part of the right end face of the circulating water tank, and the position, adjacent to the connecting end with the circulating water tank, on the first transmitting pipe is provided with a group of electric control valveselectrically connected with the control device. The experimental device for the hydrological axial flow pump is capable of, through the related devices, realizing the systemic circulating operation ofwater flow, and through installing a single-end heating tube and a semiconductor cooler, adjusting the temperature of a transmitted medium, through observing an installed turbine flowmeter, testing whether the transmission efficiency of the hydrological axial flow pump is affected while the different temperatures of the mediums are transmitted.

Description

technical field [0001] The invention belongs to the technical field of hydrological test equipment, in particular to an experimental device for a hydrological axial flow pump. Background technique [0002] Axial flow pumps are low-lift, high-flow pumps with simple structure and easy use. They are mainly used for irrigation and drainage of farmland, and can also be used for water supply and drainage in cities, circulating water in thermal power plants, and lifting water levels in docks. Studying the hydraulic model of the axial flow pump is the basis for the development of low-lift drainage and irrigation in my country. [0003] In order to improve the performance of axial-flow pumps and provide advanced hydraulic models for large-scale axial-flow pumps used in irrigation and other projects, it is necessary to conduct experiments on various factors that affect the delivery flow of axial-flow pumps, so as to provide evidence for the manufacture of axial-flow pumps. The experi...
