Definitions

  • the invention relates to an oscillating positive displacement pump, in particular Me branpumpe for liquid or gaseous media, with a delivery chamber, which is limited on the one hand by a pump head and on the other hand by a delivery element, in particular formed by a membrane, which is in drive connection with a linear actuator, whereby at the delivery chamber, an inlet valve connected to an inlet connection and an outlet valve connected to an outlet connection, are connected.
  • a delivery chamber which is limited on the one hand by a pump head and on the other hand by a delivery element, in particular formed by a membrane, which is in drive connection with a linear actuator, whereby at the delivery chamber, an inlet valve connected to an inlet connection and an outlet valve connected to an outlet connection, are connected.
  • Diaphragm pumps which are used as liquid pumps but also as gas pumps, work on the principle of oscillating displacement pumps. Naturally, this principle causes pulsation on both the suction and the pressure side. Pulsation on the suction side can cause cavitation, pressure surges and vibrations in diaphragm pumps and especially in high-speed diaphragm pumps.
  • Pressure surges can damage devices installed in the suction line or affect their function. Vibrations cause noise and are transmitted to peripheral devices or to the entire device.
  • Pulsation on the pressure side causes pressure surges and vibrations in diaphragm pumps.
  • the effects are the same as on the suction side but more radical, because on the pressure side - in contrast to the suction side - the pressure peaks can rise much higher.
  • the object of the present invention is to provide a positive displacement pump, in particular a diaphragm pump for liquid or gaseous delivery media, in which pressure peaks are avoided both on the suction side and on the pressure side, which also meets increased safety requirements and which, moreover, nevertheless has a compact structure.
  • the pump has a pulsation damper on the pressure side and an overpressure limiting device between the pressure and the suction side and that these devices are integrated in the pump head.
  • a vibration chamber is integrated in the suction-side part of the pump head.
  • An embodiment of the pressure-side pulsation damper provides that it has at least two damping chambers connected in series within the pump head or a damper housing belonging to the pump head, that for this purpose a line section connected to an inlet has a connecting channel to a first damping chamber and via an inlet throttle element is connected to a second damping chamber connected to an outlet via an outlet throttle element, and that damping elements made of resilient material are arranged within the damping chambers.
  • damping elements that can temporarily store and release the pumped medium when pressure fluctuations occur.
  • a back pressure is built up by the throttle elements during a pressure surge, by means of which a pressure charging of the damping members and a throttled delivery of the conveyed medium is possible in the pressure drop phase following the pressure phase.
  • the suction-side oscillation chamber has an oscillation membrane, which divides the oscillation chamber into a chamber part connected to the suction side and a chamber part connected to the ambient air via an opening.
  • this suction-side 5 pulsation damping does not abruptly stop the liquid flow when the inlet valve is closed, but can be kept somewhat "in the flow" by the then deflecting oscillating membrane.
  • a pulsation on the inlet side can thereby reduced . ist '0 and particularly in high-speed diaphragm pumps cavitation, pressure shocks and vibrations avoided.
  • noise is dampened and an unstable flow rate is avoided.
  • a pump P shown in the figure has a pump housing 1 to which a motor 50 is flanged on the side.
  • a crank drive for a pump diaphragm 6 has two crankshaft bearings 2, an eccentric 3 and a connecting rod bearing 4.
  • a connecting rod 5 has a connection point 15 via which it can be connected to the pump diaphragm 6. When the crank drive rotates, the pump diaphragm is set into a lifting movement.
  • An intermediate plate 7 is mounted on the pump housing 1, between which and the pump membrane 6 a delivery space is formed.
  • the intermediate plate 7 includes an inlet valve and an outlet valve when the valve plate 8 is attached.
  • the intermediate plate 7 and an adjoining connection block 9 essentially form the pump head.
  • the terminal block 9 as part of the pump head is approximately cuboid in the embodiment •.
  • One of the six sides forms a connection side for the intermediate plate 7.
  • the functional parts of an overpressure limiting device 27 are shown on the opposite side. This is used to set the maximum permissible pressure on the pressure side of the pump and has a flow connection between Pressure side and suction side, which is closed by an overflow valve in normal operation.
  • a pressure control membrane 20 engages in an inner cavity of the connection block 9 and lies there sealingly on an opening 28 connected to the suction side.
  • the pressure regulating membrane 20 is pressurized by a spring 21, the pressurization being adjustable by an adjusting screw 23.
  • a lock nut 24 with washer 25 serves to secure the respective setting of the adjusting screw 23.
  • connection block 9 for receiving the pressure control membrane 20 and the like is closed by a pressure cover 22 which is held by means of screws 26. Opening 29 connected to the pressure side can still be seen inside the recess.
  • connection block 9 On two of the remaining four sides of the connection block 9 there is a line connection 14 opposite one another
  • connection block The two other circumferential sides of the connection block have a pulsation damper 45 connected to the pressure side on the one hand and an oscillation chamber 16 on the other side.
  • the pulsation damper 45 has a large damping element 40 and a small damping element 41, which are located in separate damper chambers.
  • the damping elements can differ in terms of their mass and / or their volume.
  • the two associated damping chambers are connected to one another via a line section, which is not shown in more detail.
  • This line section has a pressure side Inlet with a connecting channel to the first damping chamber.
  • the line section is connected to the second damping chamber via an inlet throttle element, which in turn is connected via an outlet throttle element to an outlet which in turn is connected to the pressure-side line connection 12.
  • the damping elements located within the damping chambers consist of resilient material.
  • the damping chambers of the pressure-side pulsation damper 45 are subdivided by means of a separating membrane 42 into a receiving space for the damping elements 40, 41 and into a region that carries a conveying medium.
  • a damper cover 43 is provided as the outer termination of the pulsation damper 45, which here can have part or the entire volume of the damping chambers.
  • the damping chambers are fully integrated in the connection block 9. With the help of screws 44, the damper cover 43 is held on the connection block 9.
  • the oscillation chamber 16 is located on the side opposite the pulsation damper 45.
  • This oscillation chamber has an inner cavity connected to the suction side in the connection block 9.
  • a vibrating membrane 10 divides the vibrating chamber into a chamber part connected to the suction side and a chamber part connected to the surroundings via an opening 17.
  • An end cover 11, which is held by means of screws 13 on the connection block 9, serves to hold the oscillating diaphragm 10 and to close off the oscillating chamber.
  • a pulsation damper on the suction side is formed by the oscillation chamber 16.
  • a heater can be integrated into the pump head or the connection block 9. As not shown in more detail, this can include a heating plate 30 including cable connections, optionally a heat distribution plate 31 and optionally a casting compound 31. This can prevent the pump head from freezing at the appropriate pressure and temperature conditions, or it can be thawed when the pump head is frozen.
