Design On Auto-Measure System For The Compositive Test Station Of The Propulsive Water-Jet Pump

The compositive test station of the propulsive water-jet pump, as a proofing unit of the propulsive water-jet pump and a research means of the hydraulic model,, shows a indispensable important station on application spread and theoretical investigation of the propulsive water-jet pump。The design on auto-measure system for the compositive test station of the propulsive water-jet pump needs the support of a wide range of scientific disciplines, such as hydrodynamics and mechanical engineering. Moreover, there are few test stations of the propulsive water-jet pump in the international, especially, the huge test stations of the propulsive water-jet real pump is absent. During the course of the design, there are no established mathematic models and engineering experiences for reference in the literature. It is a innovative practice.The design on auto-measure system is an important part of the design of the compositive test station of the propulsive water-jet pump. It influences directly the veracity and facility. During the course of the design on auto-measure system, we have develop on MCGS configuration software, use classic cybernetic theory, adopt a lot of high exact instruments,data acquisition cards and intellectualized flow adjustive device, and so on. We have tackle key problem for a lot of important technology, finally, we developed the auto-measure system. The successful design of the compositive test station of the propulsive water-jet pump is connect with the demand of test or study, and it have attain and even exceed the precision of the correlation international standard. So, the design of the compositive test station of the propulsive water-jet pump not only supply a gap of the test on the propulsive water-jet pump, which is approved the only test station of two pieces of"important project"the propulsive water-jet pump by The Science and Industry Commission for National Defence, but also offer the advanced research means of the hydraulic model. This paper discusses the develop and design for the compositive test station of the propulsive device, it includes: the speed control system by frequency variation, the measure and induction system such as physical parameters of pressure and flow, the control system such as the electric valve and the central control console, the monitoring and managerial control system of the engineering control computer. Moreover, the paper firstly apply MCGS configuration software to measure system for the compositive test station of the propulsive water-jet pump, and firstly realize the auto-measure system of the propulsive water-jet pump, these are initiation in domestic。Moreover, the measure means between the manually measure system and the auto-measure system are compared by a great deal of test, it offers the reliable reference plans for the application.The test station has been appraised and checked,and has been put into practice. From running state, the system ran stably, and all functions ran normally, it reaches completely design requirements。Moreover the test station has a greed deal of test on the hydraulic model。So the test staion not only creates a favorable economy benefit,but also offers enough datas for researching the propulsive water-jet pump's technology。...
