Definitions
- the invention relates to a canned motor pump with a rotor space upstream of the engine to prevent passage from in the liquid contained solids and a liquid circuit for Cooling the liquid present in the rotor space.
- EP 0 438 466 B1 has also already disclosed a filter device which the problem of clogging or clogged by the fact that between the housing and the rotor shaft through a bushes made of hard material was formed limited filter gap, in which existing particles on a for the subsequent column harmless size were reduced.
- the design according to the features a and b has the consequence that the of Centrifugal generated, centrifugally directed conveying effect due to the conical course of the space surrounding the centrifugal disc at the Wall causes a directed to the pump side flow, from the in the said space results in a continuous circulation flow.
- Circulating flow is absorbed by solid particles passing through the impeller be recycled back into the directed to the pump outlet flow. This can be done with the aid of the surface roughness of the impeller or by means of Back scoops take place on the impeller.
- the feature c additionally assumes the function of a lock that only has a very low fluid passage result.
- a barrier against the passage of hot fluid into the rotor chamber is by a pump side arranged thrust bearing, which has a narrow radial gap With the housing surrounding the thrust bearing forms produced
- a Ceramic plain bearing for the pump-side bearing of the shaft within the rotor space is a Ceramic plain bearing preferred, which on the one hand directly and on the other indirectly via arranged in the shaft holes through the rotor in the Canned motor pump fluid is lubricated.
- centrifugal disc as a resilient element to train them for a biasing of the ceramic plain bearing toughen.
- the centrifugal disc can consist of a single disc consist of or composed of several discs.
- the canned motor pump shown in FIG. 1 consists essentially of a pump part 1 and a motor part 2.
- Side of the motor part 2 is a Heat exchanger 3, with the engine part 2 via pipes 4 and 5 is connected, arranged.
- a ceramic plain bearing arranged in the pressure-side housing cover 9 of the pump part 1 is a ceramic plain bearing arranged, which consists of a bearing bush 10, a motor-side thrust bearing 11, a pump-side thrust bearing 12 and a bearing sleeve 13 is made.
- Impeller 14 On the From the pump part 1 side facing away from the thrust bearing 11 is a Impeller 14, through which in the rotor chamber 15 of the motor part 2 existing Moved liquid in a guided over the heat exchanger 3 circulation becomes.
- the impeller has 7th on its side facing the pressure-side Radierraum 16 side Back vanes 17. These receive one in the direction of the pump outlet 18th pointing promotion upright and thus lead into the Radierraum sixteenth inflowing, admixed with admixtures conveying fluid again.
- such support would be in a conventionally designed Radveragingraum the penetrated dirt particles only inadequate dissipate. It would be due to the prevailing flow conditions Enrichments of dirt, which are ultimately in the range of relative to each other Moving parts would lead to progressive abrasion. moreover Dirt particles could get into the rotor chamber 15.
- An additional barrier against intrusion of remaining Solid particles in the rotor chamber 15 forms an axial gap 22 which is between the Slinger 19 and the housing cover 9 is present.
- a radial gap 23 between the thrust bearing 12 and the housing cover 9 forms a barrier against fluid communication between the space 21 and the Rotor space 15, so protects the rotor space from contained in the pumped liquid Warmth.
- promotional thread 24 on the rotating with the shaft 6 Thrust bearing 12 can be provided. Fig. 3 shows this feature.
- the located in the rotor chamber 15, circulated by the impeller 14 liquid also serves to lubricate the thrust bearings 11 and 12 This happens on the one hand directly through the surrounding liquid, on the other hand are in the shaft. 6 Holes 27 are provided, the liquid to the thrust bearings 11 and 12 lead. About holes 28 and a groove 29, this liquid finally reaches the Sliding surfaces of the thrust bearings 11 and 12.
