Control panel as shown in Figure 3.Below four nixie tubes show in real time respectively: outlet pressure (0-3.000MPa), vacuum pressure (0-100KPa), rotating speed (0-4000r/min) and flow (0-1000L/s), the water yield (0-9999m
3).
Controller has two kinds of working staties: default and operation.
According to equipment ability to bear and field requirement, preestablish Control Parameter: the pressure side-play amount is 5, and velocity bias is 20, idling desired value 100, velocity limit 2500, limit malleation are 2.
Certain operation workflow is as follows:
(1) power on, enter in manual state: manually tutorial light is bright, and other all tutorial light go out.It is bright just to change tutorial light when pressing positive turn key, and motor just changes, and decontrols button, is just changeing tutorial light and is going out, and motor stops.The counter-rotating tutorial light is bright when pressing reverse key, and button is decontroled in the motor counter-rotating, and the counter-rotating tutorial light goes out, and motor stops.Adjust mouth pressure to 1.000MPa.
(2) push control key, enter voltage-controlled state, the goal pressure tutorial light is bright: 1.000MPa is the pressure control desired value with current malleation (outlet pressure) measured value, owing to opened or close the influence of factors such as hydraulic giant.When the malleation measured value greater than pressure control desired value 1.000MPa+ pressure deviant 0.005MPa, motor counter-rotating, the counter-rotating tutorial light is bright, when the malleation measured value equaled less than malleation desired value 1.000MPa, motor stopped, the counter-rotating tutorial light goes out.When malleation measured value during less than malleation desired value 1.000MPa-pressure deviant 0.005MPa, motor just changes, and it is bright just to change tutorial light, and when malleation measured value during more than or equal to desired value 1.000MPa, motor stops, and is just changeing tutorial light and is going out.Press and increase key pressure control desired value and increase, press reduce key then the pressure control desired value reduce.
(3) press the speed control key, enter the speed control state, the rotating speed of target tutorial light is bright: with rotating speed measured value 1500r/min is the speed control desired value, when velocity measurement greater than speed target value 1500r/min+ velocity shift value 20r/min, motor counter-rotating, the counter-rotating tutorial light is bright, when velocity measurement during smaller or equal to speed target value 1500r/min, motor stops, and the counter-rotating tutorial light goes out.When velocity measurement less than speed target value 1500r/min-velocity shift value 20r/min, motor just changes, it is bright just to change tutorial light, when malleation measured value during more than or equal to speed target value 1500r/min, motor stops, and is just changeing tutorial light and is going out.Press and increase key speed control desired value and increase, press reduce key then the speed control desired value reduce.
(4) press idling, motor counter-rotating equals less than setting idle speed value 100r/min up to rotating speed, and the controlling method of stating the speed control state according to last speed is controlled at rotating speed and sets near the idling.
(5) as the velocity limit 2500r/min of rotating speed more than or equal to setting, perhaps outlet pressure is 2MPa more than or equal to the limit malleation of setting, and motor can not tighten up again, and throttle can not strengthen again, and engine speed can not improve again.
" preset/withdrawing from " key by shown in Figure 3 enters preset state, and controller still according to the selection under the running state, is being controlled motor, and this moment, the function of button changed, and was used to be provided with running parameter.
Default lamp is bright, and the flow tutorial light is bright, and the top nixie tube shows flow.By＞＞key, top nixie tube tutorial light according to flow, press partially, speed partially, idling, order very fast, extreme pressure light, by＜＜key then according to extreme pressure, very fast, idling, speed partially, press partially, the order of flow lights.Press partially, speed partially, idling, when tutorial light very fast, extreme pressure is lighted, change the numerical value that malleation deviant, velocity shifts are planted value, idling desired value, velocity limit, limit malleation with increasing and reducing key, change need just can come into force by the confirmation key affirmation at every turn.When the flow tutorial light is bright, presses increase or reduce key, flow value zero clearing.When default lamp is bright, press preset key, withdraw from preset state.
It is last with the start water yield when Fig. 3 top nixie tube powers on for showing.Be in running state: show this start water consumption (as not zero clearing, then show value is that former water consumption adds this start water consumption) when manually moving, display speed desired value during speed control shows voltage-controlled desired value when voltage-controlled.Be in state when presetting: displaying contents shows flow, malleation deviant, velocity shift value, idling desired value, velocity limit, limit malleation according to the operation of the right keyboard, and the topmost part LED lamp is corresponding one by one with displaying contents.
Flow value each second accumulative total once and store EEROM into, when the numerical value of pressure side-play amount, velocity bias, idling desired value, velocity limit, limit malleation is pressed confirmation key, be saved in EEROM.
Power switch uses the waterproof aviation plug to connect external component on the controller side.
