Definitions

  • the invention relates to a diaphragm pump with a pump part, which is subdivided by a diaphragm into a paint stage with a paint inlet valve and an unguided paint outlet valve and a drive stage with a working piston oscillating perpendicularly to the diaphragm plane and a drive chamber filled between the diaphragm and the piston end and filled with a hydraulic fluid, with a hydraulic part represents a drive fluid reservoir, which is connected via a suction line to the drive chamber of the drive stage, has a filler opening with a drive fluid dipstick and into which an eccentric seated on a shaft rotates to drive the piston of the drive stage, and with a motor as a motor part for the drive the eccentric shaft.
  • Diaphragm pumps of this type have long been known in various designs and have been on the market.
  • Diaphragm pumps which are to be operated with an add-on paint container, have a vertically upwardly projecting paint inlet valve in order to be able to place the paint container on the pump and connect it directly to it.
  • Diaphragm pumps on the other hand, which are to be fed from a paint container to be set up next to the pump, are usually provided with an inlet valve projecting laterally horizontally, so that a paint suction hose can be inserted directly from the inlet valve into the paint container.
  • Fig. 2 shows a second position of the diaphragm pump, which results from the position of Fig. 1 by a 90 ° tilt.
  • the hydraulic part 11 is located above the motor part 10, the motor shaft and eccentric shaft running vertically.
  • the pump part 12 on the other hand, is now arranged next to the hydraulic part 11, the drive piston oscillating in the horizontal direction and the membrane extending in a vertical plane.
  • Appropriate dimensioning (height, width) of the hydraulic part 11 ensures that the level of the hydraulic fluid is again at a level without removal or refilling of hydraulic fluid, as is desired for operation, for example just overlapping the eccentric bearing 13.
  • the angle of inclination of the dipstick axis is chosen accordingly, approximately parallel to the diagonal of the hydraulic part 11.
  • tube 40 extends vertically downward from point 40a, then extends horizontally after a bend, to point 40b, at which point it bends obliquely upward to point 40c after a bend.
  • the pipe is bent 90 ° vertically backwards, thus runs perpendicular to the plane of the drawing to the rear, whereupon it is bent obliquely downwards; the pipe then runs in a plane parallel to the plane of the drawing, corresponding to the visible pipe section, over the bend 40b to the point 40a, where it in turn lowers is bent over in such a way that it runs perpendicular to the plane of the drawing forward to the visible point 40a.
  • This simple but effective tubular frame 40 ensures, as shown in FIGS.
