Definitions

  • the invention relates to a water pump or dergi. and for example for pumping around cooling water for internal combustion engines, which essentially consists of the functional elements pump block and pump holder.
  • both the pump unit and the pump housing are made of metal, are screwed to one another and to the engine block via a flange connection. If replacement work is necessary, the water pump, i.e. the pump set, which is changed, e.g. with corrosion or Bearing damage, leaks, etc. is required.
  • the complete pump housing is only exchanged in the rarest of cases, unless e.g. Such an exchange is necessary for corrosion or frost damage.
  • a water pump constructed in this way has various disadvantages. So is the change, i.e. Replacing parts of such a water pump is also time-consuming because it is cumbersome, but there are also serious disadvantages, such as high weight, corrosion of the individual parts, low economic viability, also due to complex storage, and a lower efficiency, due to fluid friction within the parts of the water pump made of cast metal.
  • the invention is therefore based on the object of creating a water pump or the like which reliably avoids the disadvantages of the known pumps and similar units and which facilitates the assembly, disassembly or replacement of individual parts or assemblies and reduces them to a few manipulations, as well as a simplified structure and the possibility of combining different pump parts with each other, as well as increasing the efficiency.
  • a pump receptacle into which a pump block with a pump impeller, pump shaft, bearing, and seals and locking ring can be inserted.
  • the pump receptacle is advantageously integrated into the pump housing.
  • the pump receptacle is advantageously integrated in the cover of a pump housing.
  • the pump receptacle is advantageously integrated in the engine block.
  • the pump housing advantageously consists of a base body and a housing cover, it being possible for the housing base body and cover to be made in one or more parts.
  • the pump housing is advantageously provided with a flange connection to the engine block, with cooling water connections and a thermostat connection.
  • the elements of the pump advantageously consist partly of plastic, partly of metal.
  • the pump block is advantageously coupled to the pump receptacle with a quick-release fastener.
  • quick fasteners are provided between the pump housing and the thermostat, engine block, cooling water pipes, etc.
  • the quick-release fasteners are advantageously integrated in the pump housing.
  • a quick-release fastener which is self-retaining in the direction of rotation of the drive disk of the pump is advantageously provided between the pump block and the pump receptacle.
  • the quick-release fastener is advantageously designed as a bayonet fastener.
  • the pump block is advantageously secured with a locking ring in the opposite direction of rotation after the quick-release fastener has snapped into place.
  • the locking ring advantageously includes snap lips and locking bolts.
  • the locking ring on the pump bearing element is advantageously guided axially in guide grooves and can be locked in the unlocking and locking position.
  • the torque exerted by the drive belt, which acts on the pump bearing element via the shaft, is advantageously absorbed via an axially offset multiple bearing.
  • the pump bearing element can advantageously be combined with different pump housings.
  • the pump bearing element advantageously contains sealing elements against the drive shaft, as well as against the pump receptacle and bearings for receiving the shaft.
  • a radial seal is advantageously provided between the pump bearing element and the pump receptacle.
  • the pump impeller is advantageously made of plastic.
  • the housing cover is advantageously made of plastic.
  • the pump housing is advantageously made of plastic.
  • the pump bearing element advantageously consists of plastic.
  • the locking ring is advantageously made of plastic.
  • Sealing rings are advantageously provided as sealing means.
  • Polyamide is advantageously provided as the material for the pump bearing element, the housing cover, the pump housing, the impeller and the individual parts thereof.
  • a polyether sulfone is advantageously provided as the material for the pump parts.
  • a polyether ketone is advantageously provided for the parts of the pump.
  • the division of the water pump functional unit into parts that can be separated from one another, such as a pump block with a pump bearing element, drive shaft, sealing element bearing and pump impeller, as well as a pump holder integrated in the pump housing, housing cover and motor block means that any defective parts can be replaced without any problems.
  • a pump block with a pump bearing element, drive shaft, sealing element bearing and pump impeller, as well as a pump holder integrated in the pump housing, housing cover and motor block means that any defective parts can be replaced without any problems.
  • This also enables the pump block to be combined with different housings, for example, and vice versa, which simplifies warehousing.
  • the housing cover can be made of metal and the pump block made of plastic.
  • FIG. 1 shows a perspective view of the pump block 1 and the pump receptacle 11 in an exploded view.
  • the pump block 1 essentially consists of the pump assembly 7, the drive shaft 8, the pump impeller 9 and the locking ring 17.
  • FIG. 2 shows the pump block 1 when it is inserted into the pump receptacle 11.
  • the locking ring 17 can be provided with a cover 17a, which additionally prevent dirt from entering the pump block.
  • the two positions are ensured by the snap lips 17c in a guide groove 5 by latching.
  • the pump bearing element 7 is sealed with one or more sealing rings 10 or 10a against the housing cover 11a in the pump receptacle 11.
  • a plurality of knobs 4 are provided, which are inserted into the recess opening of the recesses 12 of the pump receptacle 11 and lock in the pump receptacle 11 after the pump bearing element 7 has been rotated.
  • a seal 10 and / or 10a seals this pump bearing element 7 from the pump receptacle 11.
  • the stiffening ribs 2 are attached to the pump bearing element 7 in order to give the pump block 1 the necessary strength in the operating state.
  • a stop edge 3 is provided in the upper part of the pump bearing element 7, which serves as a stop on the pump receptacle 11.
  • Various connections are provided in the pump housing 13, so one Flange connection 14 to the engine block, cooling water connections 15a and 15b, and a flange connection 16 for the thermostat. These flange connections can be designed in the same quick-lock type as pump block 1 with pump receptacle 11.
  • FIG. 3 shows the pump block 1 inserted in the pump receptacle 11 and locked. It can be clearly seen that the pump block 1 is inserted with the stop edge 3a up to the stop edge 3 in the pump receptacle 11 and the knobs 4 serving for locking are engaged in the recess for the locking 12.
  • the snap lip 17c slides into the undercut 6 in the guide groove 5 and the securing ring 17 covers the pump receptacle 11 and the stop edge 3a of the pump bearing element 7 on the end side.
  • the moment 18 exerted by the drive belt is absorbed by the double bearing in the areas 10 and 19.
  • FIG. 4 shows a top view of the pump block 1, the snap ring 17 with its snap lip 17c being clearly visible and also the guide groove 5 in the pump bearing element 7.
  • FIG. 5 and 6 show the anti-rotation device of the pump block 1 against the pump receptacle 11.
  • the locking bolt 17b provided on the locking ring 17 will slide after the axial movement of the locking ring 17 against the pump receptacle 11 into the recess opening of the recess 12 and thereby achieve a turnstile between the stop edge 3 of the pump bearing element 7 and the pump receptacle 11.
  • FIG. 7 shows an example of a water pump in an embodiment with pump block 1, housing cover 11 with pump receptacle 11 and pump housing 13 with thermostatic connection 16, water connections 15a, 15b and connecting flange 14 to the engine block in an exploded view.
  • Pump housing 13 and housing cover 11 a with pump receptacle 11 can be formed as a unit, the pump receptacle 11 can also be integrated into the engine block itself.
