Description
Technical field
The present invention relates to the detection technique field of engineering truck transmission valve body, be specifically related to a kind of engineering truck transmission control valve body proving installation.
Background technology
In the variator of engineering truck, in valve body, the break-make of oil circuit is the key that can Hydrodynamic transmission normally work.If blocking or fault appear in oil circuit, will directly affect the transmission performance of car load, even occur the stuck problem such as flame-out.Such Hydrodynamic transmission valve body proving installation existing generally adopts primary instrument directly to measure, and can only manually operate valve body testing procedure, especially will to certain valve body repeatedly shift gears test time, more need manually to operate, operator should Monitoring Data, operate gearshift again, workload is very large.In addition, the working electromagnet valve in valve body is more, and is installed on valve inner, defect or the solenoid valve failure of oil circuit cannot be judged during fault, only have the test by repeatedly just can complete single sleeve valve body to valve body dismounting inspection, hand labor intensity raises further, and work efficiency is lower.
Summary of the invention
The object of the invention is to: provide a kind of engineering truck transmission control valve body proving installation, to solve complicated operation existing for conventional detection devices, hand labor intensity is large, precision is low and affect the problem of work efficiency.
The object of the invention is to realize by following technical solution:
A kind of engineering truck transmission control valve body proving installation, comprise total power switch, Universal Switching Power Supply, controller and the shunt of connecting successively, controller is connected to monitoring modular and pressure transducer, controller is also connected with test start-stop button, and described total power switch and shunt are provided with external interface.
Described total power switch is connected with 220V alternating current, shunt with need detect solenoid valve and be connected.
Described monitoring modular is provided with alarm lamp.
Described shunt has 10 and specification is 2A, 200mV.
The range of described pressure transducer is 4Mpa, exports 0-5V signal.
Described pressure transducer has 6.
The invention has the beneficial effects as follows:
Compared with prior art, engineering truck transmission control valve body proving installation provided by the invention has the following advantages:
1, the equal real-time inspection and control of output input signal of proving installation, can understand the failure cause in process of the test in time, helps operating personnel to complete analytic process sooner;
2, install concentratedly, operation, display, monitoring integration, improve operability and the practicality of test process;
3, versatility is high, can adapt to dissimilar valve body test request.
Accompanying drawing explanation
Fig. 1 is system chart of the present invention;
In figure: 1-controller, 2-Universal Switching Power Supply, 3-pressure transducer, 4-shunt, 5-monitoring modular, 6-alarm lamp, 7-tests start-stop button, 8-total power switch.
Embodiment
Below in conjunction with drawings and Examples, technical scheme of the present invention is described further, but described in required protection domain is not limited to;
As shown in Figure 1, engineering truck transmission control valve body proving installation provided by the invention, it comprises total power switch 8, Universal Switching Power Supply 2, controller 1 and the shunt 4 of connecting successively, controller 1 is connected to monitoring modular 5 and pressure transducer 3, controller 1 is also connected with test start-stop button 7, total power switch 8 and shunt 4 are provided with external interface.
Described total power switch 8 is connected with 220V alternating current, shunt 4 with need detect solenoid valve and be connected; 220V alternating current is driving power, drives this device to detect the solenoid valve that need detect.
In order to show the state of monitoring modular 5 fast, described monitoring modular 5 is provided with alarm lamp 6.
Described shunt 4 has 10 and specification is 2A, 200mV, and it can complete the tracing detection of 10 solenoid valves simultaneously, effectively improves detection efficiency.
In order to ensure accuracy of detection and be controlled to pump, the range of described pressure transducer 3 is 4Mpa, exports 0-5V signal.
In order to be convenient to the oil pressure value of monitoring valve body, described pressure transducer 3 has 6.
Embodiment: during use, 220V interchange is accessed in Universal Switching Power Supply 2 by total power switch 8 and makes 220V alternating current change 24V direct current into thus power for whole proving installation; Connect shunt 4 respectively between the signal wire exporting each solenoid valve at controller 1 to, the specification of shunt 4 adopts 2A, 200mV, quantity totally ten, and the current value of electromagnetic valve work monitored by controller 1 by measuring shunt 4 magnitude of voltage.The output signal of pressure transducer 3 be connected in controller 1, the specification of pressure transducer 3 adopts range to be 4Mpa, exports as 0-5V signal, pressure transducer 3 quantity totally six, monitors the oil pressure value of valve body by measuring pressure transducer 3 magnitude of voltage.When carrying out valve body test, press total power switch 2 and test start-stop button 7 successively, then proving installation just can carry out the work of valve body gearshift loop test repeatedly, to stop test, again presses test start-stop button 7.
The valve body policy control algorithm executive routine of controller 1 presses N gear successively, 1 gear, 2 gears, 3 gears, 4 gears, 5 gears, 6 gears, 5 gears, 4 gears, 3 gears, 2 gears, 1 gear, and N keeps off; R keeps off after N gear carries out the work of solenoid valve logical combination, then carry out above-mentioned gearshift circulation, the duration of each gear is 6s.When controller 1 finds that oil pressure numerical value in monitoring modular 5, current values are abnormal, can tell that operating personnel answer checkout failure cause by alarm lamp 6.If electromagnetic valve current numerical value is lower than setting value, can judges that electric control part is divided and break down, when oil pressure numerical value is lower than setting value, then may be electric signal fault, also may be that Hydraulic Elements occur that clamping stagnation or valve body exist leakage failure.
After 100 loop tests repeatedly, the sustainable rising of working oil temperature of valve body, now fluid is thinning, be then very easy to find valve body blank whether defectiveness.
