Described wire rope is fixed on telescopic run-down pipe top, walks around pulley blocks and is wrapped on the stepper motor windlass, and the stepper motor windlass is fixed on the base.
Said wireless water level sensor, wireless pressure sensor, wireless valve controller and stepper motor driver link to each other with computing machine through wireless network.
Particularly, the working method of the utility model is following:
(1) delivery head of setting water supply installation in computing machine;
(2) computing machine through calculating calculate rotation step of stepper motor, send a signal to stepper motor driver through wireless network, stepper motor driver is received the motion of signal rear drive stepper motor windlass, adjusts the telescopic run-down pipe mouth of pipe to required head position;
(3) inlet valve is opened, and current get in the cistern tube through water inlet pipe, and when water level arrives telescopic run-down pipe nozzle position, current overflow through telescopic run-down pipe;
(4) after overflow steadily, open flowing water Valve, required current get into testing equipment through flowing water Valve;
(5) in the process of the test, water inlet, water outlet, overflow reach water yield mobile equilibrium; According to the test needs, send the instruction of adjustment head on computers, through stepper motor windlass elevating and telescopic type run-down pipe open height;
(6) according to the test needs, send through computing machine and to drive valve and instruct the wireless valve controller of inlet valve, inlet valve is regulated aperture and is guaranteed the water inlet total amount, and flowing water Valve is regulated aperture warranty test equipment water consumption.
The utlity model has following advantage:
1, adopts telescopic run-down pipe, in the laboratory, can stablize head more widely;
