Definitions

  • the present invention relates to a diaphragm or piston pump drive, with a stepper motor.
  • the stepper motor Compared to continuous motor pump drives, the stepper motor has the advantage of allowing, by electronic means, better control of the pumped fluid flow, since the stepper motor allows fine control the rotational speed of the motor, as well as knowing the angular position of the rotor without requiring an external sensor for this purpose.
  • the flow of pumped fluid can be varied by changing the rotational speed of the motor rotor, which varies the return frequency of the piston coupled to the rotor through a gear mechanism. cam.
  • the variation of the round-trip frequency of the piston can have a detrimental influence on the pressure variation in the pumped fluid, depending on the harmonic frequencies of the hydraulic system in which the pump is placed, and on the degree of damping of the pulsations or yet other factors.
  • the mechanical adjustment of the amplitude can have disadvantages in terms of the size and complexity of the system, as well as the adjustment possibilities.
  • a diaphragm or piston pump drive comprising a stepper motor, a reducing device and a mechanism for transforming the rotary motion into a translational movement, comprising a rotary member and a piston member for moving a piston or a diaphragm of the pump, the stepper motor comprising a rotor coupled, through the reducing device, to the rotary member, engaging the piston member to drive it in a substantially linear movement of back and forth, characterized in that the stepper motor and the device translation devices are adapted to perform an angular displacement back and forth of the rotary member of the translation mechanism at an angle less than 360 °.
  • the transforming device may include a cam member on the rotatable portion, engaging a complementary cam on the substantially linear moving member.
  • the angular rotation angle of the rotary cam member defines the magnitude of the linear displacement of the piston member.
  • the rotation angle of the cam is electronically adjusted by controlling the stepper motor as well as the control of the speed and accelerations of the motor, without the need for adjustment of mechanical members.
  • the flow rate of the pump can thus be varied not only by changing the piston beat frequency, but also its amplitude by an electronic control of the stepper motor, which makes it possible to optimize the operation of the pump on a large scale. range of values, ie for large and low flow rates, controlling amplitude and / or frequency.
  • the transmission of the engine torque through the gearbox implies that the motor rotor may perform several turns before the change of direction. This makes it possible to obtain a finer control of the angular displacement, in view of the reduction of the displacement through the gearbox, and to better control the ramp of deceleration and acceleration, in particular during the change of direction of rotation.
  • a pump drive 1 comprises a step-by-step electric motor 2 with a wound stator 3 and a rotor 4, a reducing device 5, a device for transforming the rotary motion into a substantially linear motion, and a piston member 7.
  • the gearbox 5 comprises gear wheels 8, 9, 10, 11 effecting a reduction of the transmission ratio between the axis 12 of the rotor and the output shaft 13 of the gearbox.
  • the transformation mechanism 6 comprises a cam element 14 integral with the output shaft 13 of the reducing device and engaging a complementary cam element 15, in the form of a freewheel, mounted on the piston member 7.
  • piston 7 is mounted in a bearing 16 of a body or support 17 of the drive to guide the piston member in a translational movement along an axis A.
  • the cam member 14 is, in this example, under form of a substantially flat disc comprising a opening 18 whose periphery 19, or at least a portion of the periphery, has the function of a cam surface engaging the complementary cam member 15 mounted on the piston member 7 for the displacement of the latter in a reciprocating motion when the rotary cam member 14 is angularly moving back and forth.
  • a first extreme angular position 20a of the cam profile corresponds to an extreme axial position of the piston member and the other extreme angular position 20b of the cam surface corresponds to the extreme axial position of the piston member. the piston member in the other direction.
  • the displacement of the cam member between the extreme angular positions 20a, 20b therefore corresponds to the maximum amplitude of the piston member.
  • Opposite surfaces 20c, 20d of the cam allow pushing and pulling of the piston member without requiring a recoil spring, which reduces frictional wear and decreases the number of components. Opposite cam surfaces also allow for high acceleration and deceleration.
  • the flow of the pump can be varied, by acting on the number of steps made by the rotor of the stepper motor before the change of direction, by an electronic control counting the number of steps and controlling the deceleration, the stop and acceleration in the other direction of the rotor of the stepper motor. It is also possible to vary the pumped flow rate by varying the speed of movement of the piston member by electronically controlling the pitch frequency of the stepper motor.
  • a speed profile of the asymmetrical back and forth movement by controlling, by means of the electronic control, the movement in a direction of rotation with a frequency of step different from the frequency in the other direction of rotation.
  • An asymmetric displacement profile can be very advantageous to optimize the suction and the expulsion of the liquid by the piston according to the characteristics of the pump and the hydraulic system, for example, to avoid cavitation during suction or shocks or vibrations during expulsion.
  • stepper motor not only has the advantage of allowing a very reliable and precise electronic control of the amplitude and the frequency according to a desired speed profile, but also of generating a high torque to relatively low rotational speeds.
  • the electronic engine control can be done through a low noise motor driver in order to avoid the known resonances of the stepper motors as well as to optimize the efficiency of the engine. . It can therefore reduce its heating by varying the current according to the operating state, for example by cutting off the current, reducing the current during the suction cycle of the pump at low pressure and providing a high or nominal current during the expulsion cycle of the pump in a situation of high hydraulic pressure.
  • the reduction device makes it possible to reduce the bulk of the engine while improving the acceleration and deceleration ramps of the rotor, as well as the positioning accuracy of the cam member, and consequently the amplitude and the frequency of displacement of the motor. the piston member.
  • the reducing device also makes it possible to absorb shocks, especially during changes of direction.
  • the output shaft 13 of the reducing device is provided with a bearing in the form of a needle bearing 21 with a small bulk.
  • the complementary cam member 15 of the piston member 7 is also mounted on a bearing in the form of a needle bearing 22 to reduce friction. between the cam surface 20 and this piece.
  • the complementary cam element 15 has a diameter slightly smaller than the radial distance separating the surfaces of the opposing cams 20c, 20d, this small clearance making it possible to avoid friction of the complementary cam element against the surface cam opposite to the engaging cam surface.
  • a cam system it is also possible to transform the rotary movement at the outlet of the reducing device by a rod system, that is to say where the piston member is interconnected to a solid disc of the output shaft of the reducing device, by a hinge pivotally coupled to the disk and the piston member.
  • the piston member need not perform a pure translational movement, as long as there is a displacement component in a direction perpendicular to the general plane of the diaphragm to vary the volume of the pump. .
