The utility model electric water boiler performance test stand comprises operator's console, cistern system, is positioned at the test support that is used to carry electric water boiler on the cistern system, and operator's console and cistern system and electric water boiler join.
Preferably, described cistern system comprises water tank, with the pipeline that electric water boiler joins, is positioned at water pump, surplus valve, pressure regulator valve and pressure transducer on the pipeline.
Preferably, described operator's console adopts qin formula structure, comprises Computer Control Test System, the LCD that joins with it, printer, dielectric voltage withstand tester, leakage current tester, voltage table, reometer.
Preferably; Said Computer Control Test System comprises industrial computer, acquisition module, electrical quantity acquisition module, DI/DO plate, relay output board, baroceptor, hydraulic pressure sensor; Industrial computer exports relay board to through the DI/DO plate; Drive the state of the solenoid control testing table pipeline of testing table; Hydraulic pressure sensor and baroceptor convert air pressure that measures and hydraulic pressure into electric signal through acquisition module entering industrial computer respectively, obtain corresponding test findings after the processing, and the electrical quantity acquisition module collects industrial computer with electrical quantity.
Preferably, the measured hydraulic pressure of hydraulic pressure sensor is the hydraulic pressure of electric water boiler water inlet pipe, and the air pressure that baroceptor detected is the air pressure of each water pipe of electric water boiler and water tank.
The beneficial effect of the utility model is: at present; The EMU of China's operation has CRH1, CRH2, CRH3 and four kinds of vehicles of CRH5; The used electric water boiler technical parameter of each vehicle is also inequality; The utility model electric water boiler performance test stand has improved overhaul efficiency, has saved construction cost, and has favorable compatibility.The electric water boiler performance test stand, its main mechanical part test support adopts adjustable fixed installation, can realize different vehicle electric water boilers is carried out installation test; Control mode is control able to programme, realizes testing requirements to the different model electric water boiler control that makes an experiment.Control system adopts system controlled by computer, operate more flexible, hommization more; All test figures show that in real time test findings is calculated automatically, have reduced the error of manual calculation; The test parameters of testing table stored distinct device can be called in the process of the test flexibly; The control system of software, combination of hardware is formed thinking, and according to the difference of testing equipment, control signal is freely switched; Adopt advanced software control function, guaranteed the robotization of test and compatibility, the unification of various preset operating modes.
Description of drawings
Accompanying drawing 1 is the system chart of the utility model electric water boiler performance test stand Computer Control Test System.
Embodiment
The utility model electric water boiler performance test stand comprises operator's console, cistern system, is positioned at the test support that is used to carry electric water boiler on the cistern system, and operator's console and cistern system and electric water boiler join.
Described cistern system comprises water tank, with the pipeline that electric water boiler joins, is positioned at water pump, surplus valve, pressure regulator valve and pressure transducer on the pipeline.
Described operator's console adopts qin formula structure, comprises Computer Control Test System, the LCD that joins with it, printer, dielectric voltage withstand tester, leakage current tester, voltage table, reometer.
As shown in Figure 1; Said Computer Control Test System comprises industrial computer, acquisition module, electrical quantity acquisition module, DI/DO plate, relay output board, baroceptor, hydraulic pressure sensor; Industrial computer exports relay board to through the DI/DO plate; Drive the state of the solenoid control testing table pipeline of testing table; Hydraulic pressure sensor and baroceptor convert air pressure that measures and hydraulic pressure into electric signal through acquisition module entering industrial computer respectively, obtain corresponding test findings after the processing, and the electrical quantity acquisition module collects industrial computer with electrical quantity.
The measured hydraulic pressure of hydraulic pressure sensor is the hydraulic pressure of electric water boiler water inlet pipe, and the air pressure that baroceptor detected is the air pressure of each water pipe of electric water boiler and water tank.
The electric water boiler water inlet pipe is carried out hydraulic pressure to be detected; Be that hydraulic pressure in order to ensure water inlet pipe enough is that water flows into water tank, guarantee having abundant water resources in the water tank, the detection of each water pipe of electric water boiler and water tank air pressure; Be in order to detect the impermeability of electric water boiler, to guarantee that leaking does not appear in the electric water boiler various piece.
Through water pump from water tank to extracardiac pumping, regulate pressure regulator valve according to the pressure of test needs, the actual pressure in the pipeline can detect through pressure transducer; Too high in order to prevent pipeline inner pressure, system is damaged, surplus valve is housed on pipeline, when pressure is higher than the set pressure of surplus valve, regulate oil pressure relief, water can make to keep constant compression force in the pipeline from the surplus valve reflow tank.
According to the air pressure of test needs, by microsystem input controlled variable, through analog output module control air pressure regulator, the actual pressure of pipeline can detect through pressure transducer.
When doing the air-tight test of valve class, the valve that detects needs installs on the pipeline, by microsystem control opens solenoid valve; Pressure in managing reaches when testing required pressure, closes solenoid valve, carries out the pressurize test; Detection demand according to valve; After the sealing regular hour, whether the pressure in the observation tube in normal range, judge whether the impermeability of valve class can reach requirement.
