Embodiment
Below in conjunction with accompanying drawing and working procedure, the utility model is described in further detail, but is not the restriction to the utility model protection domain.
As shown in Figure 1, a kind of injector control valve detection facility, comprise a controller, a pulse signal generator, the oil cylinder of a connection oil sprayer, the pressure transducer of a connection oil sprayer and a Pressure testing table, oil cylinder drives the motor of oil cylinder piston action to be connected with controller by one, the input end of pulse signal generator connects controller, the output terminal of pulse signal generator connects oil sprayer, oil cylinder is connected with the filler opening of oil sprayer, pressure transducer is fixed on the oil nozzle below of oil sprayer and is electrically connected with controller, Pressure testing table is arranged on oil cylinder one side, Pressure testing table is connected with controller.On controller, be electrically connected with an oil pressure recorder, on oil pressure recorder, be connected with a display device.Controller is the ECU that adopts closed loop control.
ECU in the utility model is self-powered.
Working procedure of the present utility model: spray the stage in advance at oil sprayer, controller (ECU) provides pulse signal affects the electromagnetic relay in oil sprayer.Meanwhile, ECU is to motor output signal, and motor is started working.Make the oil pressure in piston oil-cylinder start linear growth (limit increase, at 50bar-300bar, increases 10bar at every turn).Piston oil-cylinder one side is equipped with Pressure testing table, and the pressure signal detecting is flowed to ECU by Pressure testing table, and ECU controls oil pressure recorder and carries out oil pressure record, connects a display device on recorder, shows at any time the pressure in piston oil-cylinder.
Control valve couple in oil sprayer cannot normally be worked under the single magnetic force influence factor of electromagnetic relay, and oil sprayer is not worked.Only have in the time that oil pressure reaches certain value, under oil pressure and the two-way impact of magnetic force, control valve couple starts the oil sprayer commencement of fuel injection of normally working.Now, the pressure transducer that is placed in oil nozzle below receives the pressure of oil spout, information is fed back to ECU, and ECU is by data processing and demonstrate oil spout for the first time by display device and provide time interval and the injection duration of first pulse apart from it, and records.
When piston oil-cylinder internal pressure continues to rise, the information in each pressure stage is fed back to ECU by pressure transducer, and ECU is shown and recorded the time of oil sprayer oil spout by data processing.In the time that piston oil-cylinder pressure is greater than 300bar, information is fed back to ECU by pressure gauge, and ECU stops the pulse to electromagnetic relay, and the information that provides make motor change working state, make the oil pressure in piston oil-cylinder start to reduce.In the time that oil pressure is reduced to 50bar, the information that ECU gives by pressure gauge, stops machine operation.
