Definitions

  • Pumps especially permanent magnet clutch pumps, exist essentially a core element, a drive unit, a driver connected to the drive unit and one Housing that is at least partially the core element, the driver and encloses the drive shaft and its storage.
  • the pump is usually driven by a standard one Standard engine.
  • the required torque is based on the drivers equipped with permanent magnets via a permanent fat or oil-lubricated grooved ball bearings and transmitted an elastic coupling.
  • a So-called canister As a further component of the core element in addition to a suction and pressure chamber and an impeller stored in this is a So-called canister provided. It has the task of suction and To separate the pressure chamber from the atmosphere. Inside the containment can is the rotor that is also equipped with permanent magnets arranged. This is with medium-lubricated plain bearings stored and transmits the torque given by the driver on the impeller, just like the rotor on the pump shaft is arranged.
  • the pumps have different Bearings of the clutch shaft, different Types of lubrication and different sized housings in which the clutch shaft is supported.
  • the driver is arranged directly on the motor shaft, so that the clutch shaft is omitted.
  • the solution principle of the task is a modular one To create kit for producing such pumps, and ever depending on the application and operating mode of the pump, the desired pump assemble from a series of "standardized" components to be able to.
  • the goal is to be as little different as possible Use components for the different types of pumps.
  • the main advantage of the invention is that due to the modular kit, depending on the Requirements for the pump to be manufactured a pump inexpensively and simply made from this standardized kit can be.
  • This thermal barrier has the advantage that it is due to the drive unit due to its larger surface facing outwards protects against that that arises in the core element Heat is transferred to the drive unit. This is it possible to set the operating temperature for the drive unit limit approx. 70 ° C.
  • the kit allows one and the same components both for a block version of a pump as well as for a normal pump to use.
  • a block design of a pump is, as already mentioned, to understand that the drive unit directly coupled to the driver via the drive shaft is so that a clutch, as is normally the case with Pumping is known, consisting essentially of a clutch shaft and this shaft-bearing elements is not required becomes.
  • the component "Lantern” has a heater that go to it is the part of the medium passed through the containment shell heat.
  • a ring channel is provided inside the lantern, wherein the ring channel has a connection for performing a heating medium.
  • the ring channel itself is included mounted lantern as close as possible to the can, so that the heat caused by the heating medium immediately the liquid medium carried in the containment shell is transferred.
  • the lantern is advantageously made from a cast material, the ring channel with the lantern being a one-piece Forms part.
  • the lantern carrier for grease lubrication has a grease nipple on its circumference on, during operation as required Lubricant can be filled.
  • the other embodiment (Oil lubrication) points next to a feed opening for the Lubricant on an oil sump from which continuously Lubricant is promoted.
  • the lantern carrier suitable for the block design has a connection surface on each end on one side to accommodate the lantern and on the opposite side another pad for receiving the drive unit on.
  • the lantern carrier in two sizes to be provided, namely in a normal version and in one shortened version.
  • a thermal barrier such as it has already been described above, is to be flanged.
  • Component "magnet driver” essentially from a driver ring and a magnetic carrier designed as a driver yoke body with magnets.
  • the magnets are glued to a so-called inference body, wherein this inference body in turn in a recess in the driver ring is arranged.
  • these are Magnets arranged on the driver yoke body so that a Distance between the driver yoke body with the magnets and the front end of the driver ring is formed. This ensures that when removing or postponing the Driver rings from or onto the containment shell the magnets in front an unwanted impact and thus damage and / or Movement protected from the required position become.
  • the driver is designed so that the flange already pre-assembled on the coupling shaft can be connected to the magnet driver.
  • the driver is designed so that the Flange for connection to the drive unit first on the driver and then on the drive shaft the drive unit is connected. Because the real one Coupling without replacement is eliminated by this version considerable manufacturing costs saved, especially since the components, but also other work steps such as alignment, Straightening etc. are eliminated.
  • FIGS. 4-7 Various exemplary embodiments of Pumps, which are shown assembled in FIGS. 4-7, described.
  • the first embodiment in terms of type, refers to a standard version a pump and is particularly suitable for outputs ⁇ 15 kW suitable.
  • the clutch 18 with a clutch shaft 19 and with a flange 20 arranged at one end of the coupling shaft 19 to be pre-assembled.
  • the bearings 31, consisting of deep groove ball bearings 32, 33 already on the Coupling shaft 19 are arranged.
  • the distance 34 of the two deep groove ball bearings 32, 33 to each other larger than the norm is prescribed.
  • the flange 20 is on the coupling shaft 19 is pre-assembled with one with an outer Driver 13 provided with magnetic carrier 14 by means of screws 49 firmly connected.
  • the unit 44 thus formed is then in the Lantern carrier 21, the device for grease lubrication 37th provides, inserted.
  • the lantern 10 pushed onto the core element 2 and with screws 42 with connected to the core element, so that the face-side pad 50 of the lantern 10 with the connection surface 41 of the core element 2 comes into contact and so a further unit 43 forms.
  • the first one is formed Unit 44 pushed onto the core element 2 so that the Magnet driver 13 is pushed directly over the can to the extent that the end face 22 of the Lantern carrier 21 with the pad 45 of the lantern 10 in Connection is coming. Then they are already in the lantern carrier 21 pre-screwed screws 47 in the holes provided the lantern 10 screwed.
  • the further embodiment (Fig. 5 and Fig. 1, lower Half) of the normal version differs from the exemplary embodiment 4 in that a heat barrier 23 on the coupling shaft 19 between flange 20 and deep groove ball bearing 32, 33 is arranged.
  • the heat barrier 23 is after Pre-assembly of the coupling 18 and connection of the flange 20 with the outer magnet driver 13 directly with the front side to connect the lantern carrier 21.
  • the lantern carrier 21 for the oil lubrication 38 draws is characterized by the fact that there is an opening into which the Lubricant can be filled and an oil sump is present to at least the emergency running properties for to ensure such a camp.
  • the other embodiments differ from the previous ones in that that they are designed as a block version.
  • the main advantage of this block design is that it is very compact and none elastic coupling needed more.
  • the drive unit occurs in block design high temperatures (> 80 ° C) must be protected.
  • a lantern carrier designed in a shortened version 21 receives a heat barrier 23 on the end face prevents the high temperatures arising in the core element 2 are transferred to the drive unit 3.
