Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, this utility model is described in further detail.
Embodiment: as shown in Figure 1, 2, the one manual variable pump control system that the utility model proposes, by actuator 1,
Controller 2, electric pushrod 3 and manual variable pump 6 form.Described actuator, by regulating resistance 4 and reversing switch 5 is constituted, is adjusted
Economize on electricity resistance is for regulating the flow of manual variable pump, and reversing switch is for controlling the direction of manual variable pump reversal valve.Controller 2
Using CAN controller, its effect is according to regulation resistance 4, reversing switch 5 and electric pushrod 3 feedback signal, carries out computing
Process, reached rotating and the purpose of stroke controlling to promote motor in push rod 3.Controller is with regulation resistive power interface
With analogue signal receiving port, the power supply of regulation resistance 4 is connected on the regulation resistive power interface of controller 2, regulates the defeated of resistance 4
Go out signal to be connected on the analogue signal receiving port of controller 2.The progress signal output of reversing switch 5 and backing signal output point
It is not connected on two signal input ports of controller 2.The signal output of controller 2 and the corresponding interface of electric pushrod 3.Electronic
Push rod 3 is connected with the valve rod of the reversal valve 8 of manual variable pump by link gear 7.
Total power switch is opened, and actuator 1 and controller 2 obtain electric, and first the program within controller 2 initializes,
At this moment such as conversion valve block 8 not in middle position, cause electric pushrod 3 the most not in middle position by link gear 7, at this moment in electric pushrod
Controlling the signal of feedback element one DC 0 5V voltage of output on controller 2 receiving port, controller 2 is according to the letter received
After number processing, exporting a signal to electric pushrod 3 after having processed, electric pushrod 3 action drives link mechanism 7 to make to change
It is back to middle position state with fast speed to valve block 8.
During the work of manual variable pump, the forward/backward on-off model exported by reversing switch 5 and regulation resistance 4 export
Analogue signal be transferred in controller 2, controller 2 according to receive information carry out calculation process, processed rear controller 2
Export forward/backward signal and send electric pushrod 3 to, be used for controlling forward or reverse and the rotating speed of motor in electric pushrod 3.Electricity
Control feedback element in dynamic push rod 3, controls path increment and the rotating speed of electric pushrod 3, connection according to the signal of controller 2 output
Motivation structure 7 action along with electric pushrod 3 action, link gear 7 drives reversal valve 8 action on manual variable pump 6, to reach
Direction, flow speed control purpose.
Actuating range and the direction of reversal valve 8 are controlled by electric pushrod 3, and its control principle is by manual variable pump characteristics
Being determined, when just starting, reversal valve 8 is in middle position state, and electric pushrod 3 at this moment is also at centre position, controller 2 exports+
The voltage signal of 5V is to the control feedback element in electric pushrod 3, and electric pushrod 3 also feeds back a signal to controller 2, control
Device 2 carries out internal arithmetic, it is judged that the state of electric pushrod 3, if do not returned by electric pushrod at middle level controller one signal of output
To middle position.During if desired for manual variable pump forward motion, the reversing switch 5 in actuator is threaded to forward travel state, reversing switch 5
Export a high level progress signal to be sent in controller 2, after controller 2 receives signal internal arithmetic, defeated at controller
(its driving voltage and electric current set with joystick according to the currency of variable pump to go out front accessing port one high level signal of output
Value and change), controller output retreat output one low level 0V, make the motor main story in electric pushrod 3；If desired for manually
During variable pump backward movement, the reversing switch 5 in actuator is threaded to fallback state, after reversing switch 5 exports a high level
Bounce number is sent in controller 2, after controller 2 receives signal internal arithmetic, retreats interface output one in controller output
Individual high level signal (its driving voltage and electric current change according to currency and the joystick setting value of variable pump), controls
Device output is advanced and is exported low level 0V, makes the regulation electricity in the motor reversal in electric pushrod 3, slower rotary actuator
Resistance 4, regulation resistance 4 exports a 0 5V analogue value and enters according to regulation resistance 4 transmitted information to controller 2, controller 2
Row processes, and exports a high level signal to the control feedback element in electric pushrod 3, control electric pushrod 3 after having processed
Path increment.Controller 2 controls electric pushrod 3 according to the feedback information of manual variable pump characteristics and electric pushrod 3 and does action,
Change direction and the open degree of reversal valve 8, it is achieved the direction of manual variable pump and flow-control.
