Embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of oil hydraulic motor test stand automatic measurement and control device, constitute as shown in Figure 1, it is characterized in that: comprise the one group of sensor that is installed on the test stand 17, sensor links to each other with data collecting plate card 1 by transmitter respectively, data collecting plate card 1 links to each other with process control machine 16, and process control machine 16 links to each other with control unit on the test stand 17.Sensor comprises external control pressure transducer 7 (available KYB18G07VP2C1 type), working pressure sensor 8 (available KYB18G07VP2C1 type), rotating speed torque sensor 9 (available JN338-A-1000 type), turbine flowmeter 10 (available LWGY-10 type) and temperature transducer 11 (available 902002/20-402-1001-1-9-800-138/333 type).Control unit comprises external control pressure proportional solenoid valve 12 (available RZMO-A-010/315 type), working pressure ratio solenoid valve 13 (RZMO-A-010/315 type), throttle valve 14 (available DRVP-35 type) and relief valve 15 (available DBT107-5X/35 type).
Working principle: in oil hydraulic motor dispatches from the factory all-round property testing (combined test with the A6V107 series motor is an example), after the test beginning, application program in the process control machine is standard technological process value in the reading database at first, test stand 17 brings into operation then, data collecting plate card 1 reads the signal of each sensor output, signal value enters process control machine 16, because when just bringing into operation, need the outer governor pressure of adjusting, rotating speed and working pressure all are 0, all be not inconsistent with the database standard value, so signal value and process value are by comparing, drawing needs 16 pairs of control units of process control machine to send control signal, such as: it is that running-in is tested that motor tested for the 1st step, and its parameter that need regulate is outer governor pressure 0.8Mpa, working pressure is 15Mpa, rotating speed is 750r/min, need running-in 60s under this state.Process control machine 16 is by relatively also calculating so, to control external control pressure proportional solenoid valve 12 and working pressure ratio solenoid valve 13, the variation that output correspondent voltage value is come pilot pressure, detailed process is: the excursion of outer governor pressure is 0～5Mpa, the voltage range value of external control pressure proportional solenoid valve 12 is 0～10V, can draw the general 0.2V of being of the voltage change of 0.1Mpa correspondence, our present required external control force value is 0.8Mpa, the value of process control machine 16 external governor pressure proportional electromagnetic valve 12 outputs is about 1.6V, the correspondence but the action of the electromagnet in the external control pressure proportional solenoid valve 12 differs, so when process control machine 16 is compared with the process value of 0.8Mpa according to the pressure of the pressure end collection of exporting from external control pressure proportional solenoid valve 12, as delivery pressure during greater than 0.8Mpa, process control machine 16 deducts output signal value accordingly by subtraction, as delivery pressure during less than 0.8Mpa, process control machine 16 adds output signal value accordingly by add operation, and the outer governor pressure of output is remained on about 0.8Mpa.Adjusting for working pressure also realizes by corresponding method.Adjusting to rotating speed then is to gather the signal of rotating speed torque sensor 9 outputs by data collecting plate card 1, compare with process value 750r/min, signal value is during greater than process value, process control machine 16 is opened the switching signal of throttle orifice to throttle valve 14 outputs, reduce flow reducing rotating speed, signal value is during less than process value, and process control machine 16 is to throttle valve 14 output shutdown signals, and, increase flow to strengthen rotating speed to relief valve 15 output opening signals.When the need regulated value was all stablized, application program picked up counting, and pressure flow (P-Q) curve, flow and output torque etc. in the 60s are noted.Carry out next step adjusting record then, finish until all items.Data collecting plate card 1 can also be gathered turbine flow and temperature data by gathering the signal of turbine flowmeter 10 and temperature transducer 11 outputs.Enter data collecting plate card 1 after the processing of the signal of various sensors by transmitter.The utility model has reached closed loop control in observing and controlling, and has write down relevant parameter, has reduced the manual intervention process, has improved testing precision.
