Abstract
The utility model discloses a code wheel in plunger pump detects sensing device in succession, including the backup pad, install a step motor in the backup pad, there is a code wheel detection mechanism in step motor's the epaxial company of back play, there is a synchronizing wheel in the epaxial company of preceding play, is equipped with a dirver circuit board at step motor's rear, and the preceding of dirver circuit board is equipped with a photoelectric sensor, and photoelectric sensor corresponds with code wheel detection mechanism's position, and photoelectric sensor is used for writing down the through -hole quantity that the code wheel rotation is experienced. The utility model discloses it has increased a code wheel detection mechanism to go out the shaft position behind the motor, is connected with drive circuit through the photoelectric sensor who detects usefulness to the realization is to motor pivoted closed -loop control. When the motor rotated, photoelectric sensor can rotate the through -hole quantity that experiences by the automatic recording code wheel to judge whether correct motor pivoted angle is, with the biography insemination degree of ensureing the plunger pump.
Description
Technical field
This utility model relates to plunger displacement pump field, especially relates to the code-disc detection sensing device in a kind of continuous plunger displacement pump.
Background technology
Laboratory plunger displacement pump in the market, without to the detection of kinestate and feedback, even if step-out or overshoot phenomenon occurs in motor, user is the most unknown.And the step-out of motor and to cross punching be often to occur, although this just have found us and performs the order of a fixed journey system, its result be likely to be plunger walked a little more or few walked a bit, like this will directly influence the transmission precision of plunger displacement pump.
Utility model content
This utility model is in order to overcome above-mentioned deficiency, it is provided that the code-disc detection sensing device in the continuous plunger displacement pump that a kind of angle that can interpolate that electric machine rotation is the most correct.
The technical solution of the utility model is as follows:
A kind of code-disc detection sensing device in continuous plunger displacement pump, including gripper shoe, one motor is installed on the supporting plate, the rear shaft of motor is connected with a code-disc testing agency, it is connected with a synchronization wheel on front output shaft, is provided with one drive circuit plate at the rear of motor, before drive circuit board, is provided with a photoelectric sensor, photoelectric sensor is corresponding with the position of code-disc testing agency, the number of openings that photoelectric sensor is experienced for recording code-disc to rotate.
The back side of described drive circuit board is provided with multiturn potentiometer.
The beneficial effects of the utility model are:
This utility model position of shaft after motor adds a code-disc testing agency, is connected with drive circuit by the photoelectric sensor of detection, thus realizes the closed loop control to electric machine rotation.When electric machine rotation, photoelectric sensor can automatically record code-disc and rotate the number of openings experienced, thus judges that the angle of electric machine rotation is the most correct, to guarantee the transmission precision of plunger displacement pump.
Accompanying drawing explanation
This utility model will illustrate by example and with reference to the appended drawing, wherein:
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is described the most in a schematic way, and therefore it only shows the composition relevant with this utility model.
Code-disc detection sensing device in continuous plunger displacement pump as shown in Figure 1, including gripper shoe 1, gripper shoe 1 is provided with a motor 2, the rear shaft of motor 2 is connected with a code-disc testing agency 3, a synchronization wheel 4 it is connected with on front output shaft, it is provided with one drive circuit plate 5 at the rear of motor 2, the back side of drive circuit board 5 is provided with multiturn potentiometer 7, a photoelectric sensor 6 it is provided with before drive circuit board 5, photoelectric sensor 6 is corresponding with the position of code-disc testing agency 3, the number of openings that photoelectric sensor is experienced for recording code-disc to rotate.This utility model position of shaft after motor adds a code-disc testing agency, is connected with drive circuit by the photoelectric sensor of detection, thus realizes the closed loop control to electric machine rotation.When electric machine rotation, photoelectric sensor can automatically record code-disc and rotate the number of openings experienced, thus judges that the angle of electric machine rotation is the most correct, to guarantee the transmission precision of plunger displacement pump.
Above-mentioned is enlightenment according to this utility model, and by above-mentioned description, relevant staff can carry out various change and amendment completely in the range of without departing from this utility model technological thought.The content that the technical scope of this utility model is not limited in description, it is necessary to determine its technical scope according to right.
