Definitions
- This invention relates generally to diaphragm pumps and more particularly to a diaphragm pump, in particular for use as a detergent dosage pump comprising a pump housing, a working fluid chamber, at least one intake, at least one outlet, at least one diaphragm defining a wall of the working fluid chamber and reciprocatingly moveable, diaphragm driving means reciprocating said diaphragm and at least one check valve including a spring biassed valve body for controlling ingress of the fluid into the working fluid chamber.
- Diaphragm and piston pumps are used to supply metered quantities of liquids with various properties.
- the pump behavior is subject to various requirements in order to ensure that the delivered quantity of the metered medium is as precise as possible and remains constant for as long as possible.
- Diaphragm pumps are common industrial pumps that use positive displacement to move liquids. These devices typically include a single diaphragm and chamber, as well as discharge check valves to prevent back-flow. Pistons are either coupled to the diaphragm or used to force hydraulic oil to drive the diaphragm. Diaphragm pumps are normally highly reliable because they do not include internal parts that rub against each other. Diaphragm pumps can handle a range of media that includes abrasive materials, acids, chemicals, or the like since the drive means is normally completely separated from hydraulic part of the pump. Since diaphragm pumps can deliver small volumes of fluid with the maximum discharge, they are especially suitable as dosage pumps.
- Diaphragm pumps as dosage pumps have two strokes, i.e. an aspiration stroke in which the medium is aspirated from a reservoir and a compression stroke or delivery stroke where delivery of the metered medium e. g. into a metered line takes place.
- Diaphragm pumps known in the art for instance comprise suction check valves as well as discharge check valve to prevent back-flow. These check valves are usually spring biassed and are opened and closed by the pressure difference of the medium to be pumped. Especially when pumping highly concentrated detergents, known diaphragm pumps often fail because of crystallization and particles in the check valves.
- the valve bodies of the check valves are normally held in sealing relationship to the valve seat by means of a compression spring.
- the check valves are normally only operated by the differential pressure of the fluid. This compression spring exerts a comparatively low spring force in order to ensure that the check valve can easily be opened. This applies in particular to the check valve on the suction side of the pump.
- US patent 4,636,149 discloses a biomedical pump which includes a housing with an internal pump chamber defined by a first rigid concave wall formed by the pump body, and an opposed flexible wall defined by a diaphragm incorporating a heat responsive disc for a thermal-responsive pumping movement between a first position overlying and conforming to the body defined first wall and a second position outwardly spaced therefrom.
- An inlet passageway and an outlet passageway each communicate with the interior of the chamber through the pump body.
- Each passageway incorporates a check valve for a directional control of the fluid flow in response to the heat induced diaphragm movement.
- European patent application EP 1 462 694 discloses a valve assembly including a valve body having a valve seat surrounding a valve outlet and valve stem having a head portion adapted to contact and form a seal with the valve seat when the valve seat is in its closed state, the valve stem having an elastically deformable portion which is deformed when the valve is in the open position thereby providing a restorative force to bias the head portion towards contact with the valve seat.
- the valve assembly according to EP 1 462 694 comprises additional biasing means mounted between the valve body and the valve stem to urge the head portion towards contact with the valve seat.
- a diaphragm pump according to the preamble of claim 1 is for instance disclosed in US patent 5,279,504 .
- a diaphragm pump in particular for use as a detergent dosage pump comprising a pump housing, a working fluid chamber, at least one intake, at least one outlet, one diaphragm defining a wall of the working fluid chamber and reciprocatingly moveable, diaphragm driving means reciprocating said diaphragm and at least one check valve including a spring biassed valve body for controlling ingress of the fluid into the working fluid chamber, the diaphragm pump being characterized by additional means for mechanically pushing the valve body into its valve seat, wherein said additional means for pushing the valve body into its associated valve seat are driven by said diaphragm driving means.
- the diaphragm pump according to the invention has the advantage that even though small particles or crystals gather between the valve body and the valve seat, the valve body is forcedly pushed into the valve seat so that the basic functions of the diaphragm pump are ensured.
- the valve body is forced into the valve seat, small crystals will be destroyed so that the valve body is located within the valve seat in sealing relationship.
- check valves can shut with a comparatively high force although the spring load exerted on the valve body may still be comparatively low, so that the valve can easily be operated by the fluid pressure.
- the diaphragm pump comprises first and second check valves, the second check valve opening in the opposite direction than the first check valve.
- said second valve body constantly holds said first valve body in the closed position when the pump is not operated.
- a safety shut-off valve is provided. This is particularly advantageous insofar that for instance a detergent container may be arranged higher than the pump. The shut-off function prevents very effectively flow through the pump in the event the pump is not operated.
- the second valve body is coupled to the diaphragm drive means and is reciprocated synchronously with the stroke of the diaphragm.
- said second check valve forms part of said diaphragm.
- This design has in particular the advantage that the dead space or dead volume (difference between the total volume of the working fluid chamber and volume of displacement during the compression stroke) is minimized to such an extend that the pump according to the invention is even unsusceptible to sucking air during start-up. Due to the minimization of the dead volume, even compressibility of air which is trapped into the system does not affect the operation of the pump.
- the second valve body may be yieldingly held in sealing relationship against the diaphragm, thereby closing an aperture in the diaphragm at least during a first stroke (aspiration stroke) of the diaphragm and establishing fluid communication between said working fluid chamber and said outlet during a second stroke (compression stroke) of the diaphragm.
- said second valve body and said diaphragm are spring biassed against each, other so that pressure built up during the compression stroke of the diaphragm is determined by the elastic resilience of the spring.
- the diaphragm Since the second valve body is only lifted from its valve seat when the pressure built up during the compression stroke within the working fluid chamber has reached a certain level, the diaphragm has an extremely efficient pressure ratio.
- said diaphragm drive means is a solenoid drive.
- a bend lever drive or an hydraulically operated drive or a pneumatically operated drive may be provided.
- the second valve body comprises a stem coupled to the armature of said solenoid drive.
- figure 1 shows an exemplary embodiment of the diaphragm pump 1 consistent with the present invention.
- the diaphragm pump 1 comprises a pump housing 2 with an intake 3 and an outlet 4, the intake 3 being the suction port and the outlet 4 being the pressure port.
- a pump chamber 5a, 5b is defined within the pump housing 2.
- the pump chamber 5a, 5b houses a main diaphragm 6 which divides the pump chamber into first and second compartments 5a, 5b.
- the intake 3 communicates with the first compartment 5a of the pump chamber defining the working fluid chamber, the outlet 4 communicating with the second compartment 5b of the working fluid chamber.
- the diaphragm pump 1 comprises first and second check valves 7 and 8, the first check valve 7 controlling the intake 3, the second check valve 8 being arranged in series with the first check valve 7, as will be explained hereinafter in greater detail.
- the first check valve 7 comprises a mushroom-like first valve body 7a which is spring biassed against the first valve seat 7b, by means of a first compression spring 7c.
- the first valve body 7a is sealed against the first valve seat 7b by means of a sealing ring 7d, preferably by means of a O-ring sealing.
- the diaphragm 6 is reciprocatingly driven within the pump housing 2 by a solenoid drive only the armature 9 of which is shown in the drawings.
- the armature 9 of the solenoid drive is coupled to a stem 10 of a second mushroom-like valve body 8a.
- the stem 10a of the second valve body 8a penetrates an aperture 11 in the centre of the main diaphragm 6.
- the second valve body 8a is held spring biassed in sealing relationship against the main diaphragm 6, thereby sealingly closing the aperture 11.
- a second compression spring 8c which rests on the base 12 of the stem 10 forces the main diaphragm 6 against the sealing surface 13 of the second valve body 8a.
- the surface of the main diaphragm forming the inner wall of the first compartment 5a is provided with an annular sealing rib 14.
- a rigid holding member 15 with a peripheral collar 16 for abutment of the second compression spring 8c is provided.
- the main diaphragm 6 with its central aperture 11 does form part of the second check valve 8.
- the armature 9 of the solenoid drive is sealed against the second compartment 5b of the pump chamber by an auxiliary diaphragm 17 which has only sealing function as it synchronously reciprocates with the main diaphragm on operation of the diaphragm pump 1 as will be explained hereinafter.
- the stem 10 of the second valve body 8a penetrates the holding member 15 and the aperture 11 of the main diaphragm 6. Between the stem 10 and the aperture 11 and between the stem 10 and an aperture 18 in the holding member 15, the aperture 18 being in alignment with the aperture 11, an annular gap 19 is formed which establishes fluid communication between the first and second compartments 5a and 5b when the second check valve 8 opens.
- figure 1 shows the diaphragm pump according to the invention during the aspiration stroke.
- the armature 9 of the solenoid drive is retracted (i.e. moved to the right in figure 1 ).
- the main diaphragm 6 and the auxiliary diaphragm 17 are moved synchronously with the armature 9.
- the volume of the first compartment 5a increases so that suction is applied to the intake 3. This causes the first valve body 7a to lift from its associated first valve seat 7b against the pressure of the first compression spring 7c.
- the first compartment 5a of the pump chamber is now in fluid communication with the intake 3 allowing ingress of the medium to be pumped into the first compartment 5a.
- the fluid may enter the first compartment 5a through an annular gap 20 between the first valve body 7a and the first valve seat 7b.
- the compression force exerted by the first compression spring 7c is comparatively low so that only a little pressure difference between the first compartment 5a and the intake 3 is sufficient to allow the medium to be pumped to flow into the compartment 5a.
- FIG 2 the diaphragm pump 1 according to the invention is shown during the compression stroke.
- operation of the solenoid drive causes the armature 9 connected to the stem 10 of the second valve body 8b to reciprocate within the pump housing.
- the pumping action is thereby mainly performed by the main diaphragm 6.
- the volume of the first compartment 5a will be decreased, which causes pressure built up in the compartment 5a.
- the spring force of the first compression spring 7c causes the first valve body 7a to move into its associated valve seat 7b. This movement is supported by the rising pressure within the compartment 5a.
- the rising pressure within the first compartment 5a acts on the main diaphragm to the effect that the main diaphragm 6 is pushed against the spring force of the second compression spring 8c which is compared to the first compression spring 7c relatively strong.
- first and second valve body 7a and 8a are arranged such that their paths of travel intersect. That is to say that the second valve body 8a at the end of the compression stroke pushes the first valve body 7a into its closed position. For instance in the event that the first valve body should be jammed in its open position due to particles or crystals gathering between the sealing ring 7d and the associated sealing surface of the valve body, the second valve body 8a would push the first valve body 7a by force into its closed position.
- Figure 3 shows the initial situation of the pump when the solenoid drive is not operated.
- the first valve body 7a is constantly held in its closed position by the second valve body 8a, so that the first and second check valves function like a security shut-off valve.
- the second valve body 8a forms part of the diaphragm drive mechanism as it reciprocates the main diaphragm 6 within the pump housing 2.
