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.
  • Such diaphragm pumps have long been known in various designs, for example. from FR-2 424 072, and 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.
  • suction hoses or pipes are required which have a bend of 180 °, which makes the paint suction process, or at least its start, more difficult.
  • the object of the present invention is therefore to design a diaphragm pump of the type mentioned at the outset in such a way that it is fully suitable for both of the above-mentioned operating positions.
  • the solution to this problem results from the characterizing features of patent claim 1.
  • the pump according to the invention thus has two setting positions, a first setting position for placing an add-on paint container, a second setting position for connecting a standing paint container, the transition from one setting position to the other being achieved simply by tilting the pump by 90 ° becomes.
  • two adjustment positions there is no additional construction effort compared to conventional diaphragm pumps.
  • the diaphragm pump is shown in sketch form, only those in direct connection with the invention standing elements are drawn.
  • the - known - basic structure of such a diaphragm pump should therefore be briefly explained in advance.
  • the diaphragm pump consists of three building blocks, namely a motor part 10, a hydraulic part 11 and a pump part 12.
  • the motor part 10 is an electric motor of suitable power.
  • the hydraulic part 11 is designed as a storage tank for the hydraulic fluid and has a rotating shaft with an eccentric 13, a filling opening with an inserted dipstick 14 for determining the level of the hydraulic fluid and a hydraulic fluid suction line 15.
  • the pump part 12 is divided by a membrane into a drive stage and a color stage. In the drive stage, a drive piston oscillates in a direction perpendicular to the membrane plane, a drive chamber being filled with hydraulic fluid via the intake line 15 of the hydraulic stage between the piston end and the membrane.
  • the ink stage consists of an ink chamber adjoining the membrane as well as an ink inlet valve and an ink outlet valve, the ink inlet valve generally being designed as a guided valve.
  • the motor shaft of the electric motor drives the shaft with the eccentric of the hydraulic part and the eccentric 13 rotating therewith directly or indirectly the drive piston of the drive stage of the pump part.
  • the hydraulic fluid in the drive chamber which is supplied via the suction line 15, transfers the piston movement to the membrane, which in turn sets the paint in the paint chamber and supplied via the paint inlet valve 16 to the desired pressure, the pressurized paint then passing through the outlet valve 17 is promoted.
  • motor part 10 and hydraulic part 11 are connected in a side-by-side arrangement such that the - not shown - motor shaft of the electric motor 10 and the eccentric shaft of the hydraulic part 11, also not shown, run horizontally, the eccentric shaft extends in the axial extension of the motor shaft.
  • the two shafts are connected to one another or, which is very simple, particularly in the case of electric motors, is formed in one piece.
  • the pump part 12 is fastened on the hydraulic part 11 in such a way that the membrane (not shown) of the pump part 12 extends in a horizontal plane, with the drive stage below, the ink stage above the membrane pump.
  • the drive piston of the drive stage also not shown, extends vertically from the eccentric of the hydraulic stage designed as an eccentric bearing 13 upward into the drive stage.
  • the dipstick 14 is inserted into the filling opening of the hydraulic part 11 in such a way that it has an inclined position with respect to the vertical, approximately parallel to the diagonal or spatial diagonal of the hydraulic part 11.
  • the suction opening 15a of the suction line 15 is located far below the liquid level indicated at 18.
  • the paint inlet valve 16 projects, as usual, vertically upwards from the top of the pump part 12; the valve 16 is a guided valve.
  • This position of the diaphragm pump is particularly suitable for placing a paint reservoir on the top the ink level of the pump part 12, as indicated in FIG. 3A, in which an ink tank 19 is placed on the diaphragm pump.
  • 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.
  • the guided inlet valve 16 now extends horizontally, whereas the outlet valve 17 again has an inclination of 45 ° with respect to the horizontal, i.e. an inclination equal to that in the position of FIG 1.
  • the unguided outlet valve 17 is thus subjected to the force of gravity in the same way in both setting positions of the diaphragm pump, so that the valve 17 works the same in both setting positions and also no readjustment is required when the diaphragm pump is transferred from one setting position to the other .
  • the inlet valve 16 extends in the two adjustment positions in different (mutually perpendicular directions), but this is irrelevant because, as mentioned, this valve is a guided valve. 2 is particularly suitable in the event that the paint is removed from a standing container, for example from a standing container 20 as shown in Fig. 3B.
  • the diaphragm pump can be provided with a housing-like covering, on which there are feet for each of the two setting positions for placing the pump on the floor.
  • additional handles can be attached to the housing, for example two U-shaped tube handles.
  • the diaphragm pump can also be used without any casing in a frame which has feet or foot-like shapes in both setting positions for switching off the pump.
  • the frame itself can be designed so that it can accommodate both the complete pump and molded handles, whereby the arrangement of the handles must take into account the particular center of gravity of the pump frame unit. 4 and 4A, such a frame is attached to the pump.
  • the frame 40 consists of a single piece of pipe which is bent accordingly, whereupon its abutting ends are connected to one another, so that an endless pipe is formed, so to speak. Referring to FIG.
  • 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 backwards 90 ° vertically, thus running backwards perpendicular to the plane of the drawing, whereupon a downward bending takes place; 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 is perpendicular is bent so that it extends 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.
  • the pump frame unit is carried in the position of FIG. 4A on the cross pipe going out at 40c, in the position of FIG. 4B on the two pipe bends 40b, which can be connected to one another by a horizontal pipe section.
  • FIGS. 5A and 5B A further possible embodiment of a diaphragm pump frame unit is shown in FIGS. 5A and 5B, which is a mobile frame.
  • a tubular frame 50 in the form of an elongated rectangle is angled centrally with respect to its long side, the two bends being connected to one another by a wheel axle 51 with wheels 52.
  • the outer end pieces 50a and 50b of the tubular frame 50 are bent over again, to the outside.
  • a drawbar 53 is articulated on the wheel axle 51 and can be locked both at the end piece 50a and at the end piece 50b. In the setting position shown in FIG. 5A, the drawbar 53 is locked at the frame end 50b and the frame end 50a represents a stand, whereas in the second setting position shown in FIG.
  • the drawbar 53 is locked at the frame end 50a and the frame end 50b the stand represents.
  • the diaphragm pump can be moved and / or set up in the desired setting position.
  • the pipe bend 50c shown in FIGS. 5A and 5B only represents protection for the diaphragm pump when it is in the actuating position in FIG. 5A.
  • the invention can undergo numerous modifications without leaving the scope of the invention. So it is possible, for example, the paint inlet valve with eggs 45 ° position to provide, but this is generally only useful if the paint inlet valve is also an unguided valve. Furthermore, it is understandable that many designs are conceivable and applicable for the support or chassis and for the cladding provided with feet.
