Water pump simulation environment multifunctional test bench

Abstract

The invention relates to a water pump simulation environment multifunctional test bench, which comprises a temperature-adjustable test box used for placing a to-be-tested water pump, a temperature control assembly used for regulating and controlling water temperature is arranged outside the test box, the water pump and the temperature control assembly are communicated through a pipeline and form a circulation loop, and a filter is arranged on the pipeline; the filter comprises a barrel, a barrel-shaped filtering assembly is arranged in the barrel, a liquid collecting cavity is formed between the filtering assembly and the inner wall of the barrel, a liquid inlet communicated with the filtering assembly and a water outlet communicated with the liquid collecting cavity are formed in the barrel, and a slag discharging opening is formed in the bottom of the barrel and communicated with the bottom of the filtering assembly. A control piece used for controlling opening and closing of the slag discharging opening is arranged outside the barrel, and one end of the control piece is in sliding fit with the barrel and elastically abuts against the barrel to seal the slag discharging opening. The device has the advantages that the scale in the filter can be conveniently cleaned, and meanwhile, the influence on the water pump performance test precision due to scale cleaning is reduced.

Description

technical field [0001] The present application relates to the field of water pump performance test equipment, in particular to a water pump simulation environment multifunctional test bench. Background technique [0002] The water pump can convert the mechanical energy of the prime mover into the kinetic energy of the fluid, so as to transport the fluid or pressurize the fluid. As the most commonly used fluid delivery equipment, the water pump plays an indispensable role in industrial and agricultural production and daily life. [0003] In practical applications, the performance of the pump may be affected by different working environments. Therefore, before the pump leaves the factory, it is necessary to use a pump performance test bench to simulate different working environments to test the performance of the pump to ensure that the pump is reliable in a specific working environment. to run. [0004] In the related art, the water pump performance test bench generally incl...

AI Technical Summary

Problems solved by technology

[0006] In view of the above-mentioned related technologies, the inventor believes that after a period of use, the scale in the filter needs to be cleaned. In the related technologies, it is generally necessary to disassemble the filter and take out the filter net from the filter. The installation process is cumbersome, and cleaning is more inconvenient

In addition, after the high-temperature test, in order to prevent burns, the filter needs to be completely cooled before removing the filter. In the next test, the temperature of high-temperature tap water flowing through the filter will be affected to a certain extent, which will affect the pump performance to a certain extent. test accuracy
