Definitions
- the invention relates to a seal of the metering piston-cylinder unit of piston diaphragm pumps and a piston diaphragm pump for suctioning and dispensing a liquid metering medium with a pump interior and by immersing a metering piston in a compression unit arranged in the pump interior, the compression chamber being a metering opening for dispensing the metering medium and the interior of the pump has a suction valve for feeding in dosing medium and a return valve for dispensing excess dosing medium.
- the accuracy of dosing with piston diaphragm pumps depends on the accuracy of the sealing of the dosing piston in the associated cylinder unit.
- mechanical sealing elements for example O-rings
- this object is achieved according to the invention in that a metering piston-cylinder unit is used which is virtually free of play in the micrometer range and is sealed by means of a hydrodynamic gap seal.
- this object is achieved according to the invention in that the metering piston in the region of the cylinder forming the compression space is guided with almost no play with a tolerance in the range of ⁇ m and the seal of a gap remaining between the metering piston and the cylinder is sealed as a seal by means of the sucked-in metering medium. hydrodynamic gap seal is formed.
- Such a sealing of the metering piston-cylinder unit of piston diaphragm pumps or piston diaphragm pumps provided with such a sealing have the advantage that the hydrodynamic gap seal works without wear and thus allows practically unlimited service lives with regard to the sealing of the system.
- the metering piston and the cylinder are made of oxide ceramic, as the invention provides in one embodiment.
- the production of the element pairing of the metering piston-cylinder from oxide ceramic has the particular advantage that the narrowest tolerances can be easily represented in terms of production technology.
- the invention also provides that the metering piston is actuated in a floating manner via a clutch or, in the case of the piston diaphragm pump, the metering piston is floating with a clutch by means of a clutch Drive piston is connected.
- the floating control of the dosing piston via a coupling enables simple assembly and ensures problem-free use of the dosing piston-cylinder unit.
- a drive with a drive piston 5 projects laterally into the diaphragm pump.
- a membrane 6 is arranged in a circular sealing manner in a pump interior 14.
- the membrane 6 is clamped tightly peripherally and allows a back and forth movement by the drive piston 5 in its directions of movement indicated by a double arrow.
- the drive piston 5 with a membrane 6 arranged thereon performs a lifting or suction movement (suction stroke) and in the direction of the pump interior 14 to a pressure movement (pump stroke).
- a metering piston 1 and a cylinder 2 are arranged as a cooperating pair of elements within the pump interior 14.
- the metering piston 1 and the cylinder 2 form a metering piston-cylinder unit.
- the metering piston 1 is connected via a clutch 4 to the drive piston 5, so that its stroke and pressure movements are transmitted to the metering piston 1.
- the cylinder 2 is penetrated by a control bore 8.
- a metering opening 11 of the piston diaphragm pump opposite the diaphragm 6 is controlled via a pressure valve 9.
- the piston diaphragm pump has a suction valve 7 and a return pressure valve 10 on opposite sides of the pump interior 14.
- the gap 3 between the metering piston 1 and the cylinder 2 is sealed hydrodynamically by means of the liquid metering medium located in the pump interior 14 and in a compression chamber 15.
- the metering piston 1 is in this area of the cylinder which forms the compression space 15 2 with a tolerance in the range of ⁇ m (micrometer range) with almost no play.
- the piston diaphragm metering pump works in such a way that when the diaphragm moved by the drive piston 5 moves in the direction away from the pump interior 14 (suction stroke), dosing medium or product is drawn in via the suction valve 7 and in the compression space 15 of the dosing piston-cylinder unit 1, 2 a vacuum or negative pressure arises. If the control bore 8 in the cylinder 2 is released with a corresponding stroke movement of the metering piston 1, the product conveyed by the stroke movement of the diaphragm 6 into the pump interior 14 flows into this compression chamber 15. During the pressure movement (pump stroke) of the drive piston 5 with the metering piston 1 in the direction of the metering opening 11 out, the control bore 8 is closed again.
- the coupling 4 connecting the metering piston 1 and the drive piston 5 has a shape adapted to the corresponding end face of the membrane piston 5 in the direction of the drive or membrane piston 5 and connects the metering piston 1 and the drive piston 5 “floating”, so that here due to installation and manufacturing tolerances , for example, a center offset can be compensated in a simple manner, which enables cost-effective production, since the specification of narrow tolerances due to the “floating” connection is avoided.
