Abstract: A diaphragm for a pump, in particular a double diaphragm pump for conveying high-purity products, having peripheral radially offset annular beads, such that one of the annular beads is a grooved bead having a groove along its interior surface, and a clamping ring inserted in the groove formed therein, and wherein the groove is in communication with a pressure medium.
Filed: May 6, Date of Patent: August 8, Assignee: Almatec Techische Innovationen GmbH. Double membrane pump. Abstract: A double membrane pump comprising a central housing 1 , two coaxial product chambers 6 in the central housing, suction and pressure valves for each product chamber, two membranes 7 sealing off the product chambers externally from coaxial pressure fluid chambers 8 , piston rods 13 guided in external seals, a U-shaped external crosspiece 17 connecting the piston rods of the membranes and a control block for reciprocally pressurising the pressure fluid chambers with pumping medium and comprising a slide valve 20 actuated by the movement of the membranes.
In particular, however, they can also be operated against closed discharge lines without an additional overflow valve. On account of the compressed-air drive, separate driving means with their required base plates and couplings are unnecessary. Diaphragm pumps of the kind described above are especially compact and easy to transport, and can be used independently of other power sources, such as especially electrical power.
Since no sliding or rotating parts operating in close tolerances are necessary and the velocities of movement are low, abrasive, viscous and shear-sensitive media can be pumped without difficulty.
By changing the rate of delivery of the compressed air the pump also can be regulated very simply, without the need for expensive and complex regulating means. However, the compressed air control means, which is represented in FIG. The control valve piston used in the known apparatus as shown in the drawing operates as a two-position valve, which alternately communicates the air chamber represented on the left in FIG.
Another environmentally undesirable circumstance is the fact that the oil mist drawn into the drive air from the oil tank to lubricate the piston is undesirably mixed with the exhaust air and can contaminate the surroundings of the diaphragm pump adjacent the exhaust, unless expensive traps and filters are provided.
Lastly, at certain positions of the control valve piston a direct path is created between air in areas under the operating pressure and those areas of the pressure control system that are under atmospheric pressure, so that in these valve positions an undesirable loss of compressed air takes place. To sum up, it can be said that the known compressed-air driven double diaphragm pump represented in FIGS.
THE INVENTION. This object is achieved by the fact that the main control valve piston is driven by a pneumatically operating pilot control means having a pilot control valve piston, wherein the pilot control valve piston is in turn operated by the movement of the diaphragm assembly. By this pressure equalization, which in the state of the art could not be achieved, an improvement of the efficiency is obtained, on the one hand, due to the fact that the unavoidable dead space in the air chambers is filled not by the operating air itself, but by the air vented from the other chamber, before the air chamber is connected to the operating air by the main control valve piston.
By the design in accordance with the invention, it becomes possible to use plastic-to-metal sealing surfaces instead of metal-to-metal sealing surfaces, so that oil mist lubrication can be dispensed with.
This not only prevents contamination of the environment with oil mist, but also the air losses due to clearances between the valve piston and valve housing can be largely eliminated, since the metal-to-plastic seals are much tighter than metal-to-metal sealing surfaces. Since the pressure blow-off that occurs in the exhaust is reduced by the pressure equalization, the danger of icing at the air exhaust is also reduced, so that the pump of the invention can be operated with a higher output than pumps of the state of the art, without greater danger of icing up.
The invention will be further explained hereinafter in conjunction with an embodiment which is represented in the drawings, wherein:.
The pumping chambers are in communication through ball valve means 30 having a common suction line 32, which in turn is connected to a reservoir supplying the medium that is to be pumped, and by an additional valve 28 to an again common discharge line 34 communicating with the apparatus to which the material is to be pumped.
The diaphragm assemblies 16 each comprise diaphragm plates 36 each bolted to the end of a diaphragm plunger 38, holding hermetically between them, by its inner margin, an annular diaphragm 40 consisting of a pliable material, while the outer margin of the annular diaphragm 40 is held hermetically between the margins of correspondingly shaped parts of the pump housing This system consists of an air control valve housing 42 which can be bolted to the pump housing, and which has an inlet 44 for working air and an outlet 46 for exhaust air.
The outlet 46 leads into a muffler 48 which is to damp at least part of the noise of the exhausted compressed air. The known air control valve housing of FIG. These movable parts include a metal piston 52 which can be moved back and forth between two end positions in a corresponding cylinder 54 consisting of metal and formed by the housing In the position represented in FIG.
At the same time the other diaphragm on the left side is drawn inwardly and thus aspirates fresh product from the suction line 32 through the lower ball valve 30, represented in the left, into the left-hand pump chamber During this period, the left air chamber is connected by a passage to the exhaust chamber 64, this passage being formed by corresponding ports in the air control valve housing 42, identified by the reference numbers 60 and 62, each to a corresponding passage 58 within the piston At the same time the air chamber 66 above the piston 52 is vented, so that, in spite of the fact that compressed working air is being fed to this chamber through narrow nozzles, the upper air chamber is nevertheless vented.
The lower air chamber corresponding to piston 52, however, is not vented, so that there the working air leads to a pressure build-up finally moving the piston 52 upwardly and away from the position represented in FIG.
At the same time the corresponding connection between the left air chamber and the exhaust chamber 64 is broken, so that pressure can then be built up by the working air in the left air chamber, so that the operating cycle is repeated inversely. The known air control valve thus supplies both air chambers with working air under all conditions, no matter what the position of the diaphragms. The diaphragm movement is performed in each case by the venting of the air chambers.
This construction of the air control valve requires only one movable piston, which is provided in FIG. In FIG. Also, the novel compressed air control system 22 comprises an air control valve housing 42 having an inlet 44 for incoming air and an outlet 46 for exhaust air. A muffler can be provided here, too, but on account of the substantially lower compressed air noise, in accordance with the invention, it is not essential.
There is no oil reservoir here, either, since the piston 52 is mounted in its cylinder such that no metal-to-metal friction takes place, as will be explained further on.
The compressed air control system 22 represented in FIG. The view represented in FIG. As seen in FIG. The pilot valve piston 70 is shaped such that, in this position it connects a central port 78 in the pilot valve cylinder 80 with a port 82 on its right as seen in FIG. The port 78 can also be seen in FIG. As it can be seen, the working air fed to the inlet 44 flows through a dust filter 84, for example, into the air inlet chamber 86 and from there to the passage 88, from which the air passes through the port 78 into the annular chamber 90 formed by the pilot valve From there the air then passes, with the pilot valve 70 in the position shown in FIG.
The right end of the main valve 52 represented in FIG. This position is represented diagrammatically also at the top of FIG. Like the pilot valve, the main valve 52 together with its cylinder 54 forms annular chambers 98, and which serve for the interconnection of various passages which in turn terminate in ports which are visible partially in FIG.
In addition to these three rather broad annular chambers 98, and , the main valve 52 also forms two narrow annular chambers and , which communicate with one another through a bore in the valve piston 52 and through a radial bore and each extending from this axial bore As it can be seen from FIG. The ports in cylinder 54 which are associated with the connection to the right air chamber, however, are to be seen in FIG.
These ports open see FIG. Since otherwise the annular chamber communicates through openings located above the plane of the drawing in FIG. The corresponding ports for the other air chamber can again be seen in FIG.
The condition described above will not continue for long. Due to the incoming air flowing through the central passage of the main valve 52 and entering into the lefthand air chamber, the pressure in the left air chamber will increase, and when it reaches the pressure prevailing in the corresponding pump chamber, the left diaphragm, and with it the corresponding diaphragm plate and the piston rod 38, will be shifted leftward.
This causes the diaphragm plate to move away from the end of the pilot valve piston The pilot valve, however, will remain in its place, since the right-hand membrane with its corresponding diaphragm plate will not reach the right end of the pilot valve piston 70 and push it to the left until the end of the pumping stroke. As it can be seen in FIG. Thus the main valve 52 begins to shift to the right, but only slowly, since the air on the right side of the main valve piston 52 has to flow through the port 96 and the passage 94 past a constriction into the right air chamber which at this time is vented, the construction being formed by a ring which is borne by the pilot control valve piston and has an only slightly smaller diameter than the inside diameter of the pilot valve cylinder The annular gap thus resulting between the cylinder wall and the outer circumference of the nozzle ring is so dimensioned that under the working conditions the main valve is moved in the opposite direction at a predetermined reduced velocity.
There is a special reason for this. As can be seen in FIG. By reference to FIG. Air chambers 20 and thus connected to main valve 52 See FIG. It has already been stated that it is desirable to bring about a pressure equalization between the two air chambers prior to the stroke reversal of the diaphragm pump, because thus, on the one hand, pressure energy is better utilized and thus efficiency is improved, and on the other hand, the exhaust air released to the free atmosphere has a lower pressure than the working air, so that the exhaust noise is reduced and the danger of icing up is reduced.
