CAMP CARRIER OUT STAHLDRAHTGESTRICK FOR A GAP PIPELINE MOUNTED PUMP
Camp carrier from Stahldrahtgestrick for a gap pipeline mounted pump The invention concerns a camp carrier in the front, the pump impeller turned range of a gap pot or a Spaltrohres of a centrifugal pump. In order to store the pumping and engine wave of a centrifugal pump to their gap pot or Spaltrohr, it is well-known to press into the Spaltrohr at the input side a camp carrier with outer ring from sinter bronze which covers a filter ring, in which a radial bearing from coal graphite in-lies. Such a construction is relatively complex when production and assembling. Task of the invention is it to improve a camp carrier of the kind initially specified in such a way that it exhibits when simple assembling and production of fewer parts. This task is solved according to invention by the fact that the buchsenförmige camp carrier consists exclusively of a pressed Drahtgestrick made of high-grade steel, which surrounds the radial bearing of the engine wave as filter ring. With only one part in form of a Drahtgestrickes pressed to a socket both the function of the connecting piece and centering the radial bearing is reached and the function of filtering. Thus a part is needed and a mechanical treatment is void less. Also a simple assembly and economical production are given. Furthermore it is of advantage that the camp carrier is free from non-ferrous metals, so that with such camp carrier provided pump can be used also for drinking water. Particularly favourably it is here that the Drahtgestrick consists of stainless steel. Preferably it is suggested that the camp carrier in the front gap pot or gap pipe aperture without surrounding (s) intermediate part (of e) is press inable. Furthermore it is given that into the camp carrier the radial bearing is press inable. It is particularly favourable that form and solidification of the camp carrier take place via a Pressvorgang. As substantial advantage it is to be regarded that the camp carrier with its outer circumference is in direct contact with the inner wall of the gap pot and/or Spaltrohres. A remark example of the invention is represented and in the following is more near described in the designs. Show Fig. 1 a front view of a gap pot with assigned radial bearing and camp carrier, Fig. 2 an axial profile by a gap pot with radial bearing and camp carrier. A gap pot 1 with front, the gap pot entrance opening 2 surrounding flanschförmigen sign 3 is intended to the installation into a not represented centrifugal pump, in order to store in the gap pot the rotor 6 of the electric motor with its driveshaft 7, which the pump propels. In that a buchsenförmiger filter ring 4 is pressed in to the pump chamber turned opening 2 of the gap pot 1, which is from a Edelstahldrahtgestrick into the socket form pressed and solidified. Within the filter ring 4 a buchsenförmiges radial bearing 5 from coal graphite is pressed in, whereby filter ring 4 and radial bearing 5 are coaxially to the engine and pump wave as well as to the axle of the gap pot 1 arranged. The buchsenförmige filter ring 4 rests thereby externallaterally directly against the inner wall of the Spaltrohres and/or the gap pot 1, so that outer ring between filter ring 4 and inner wall of the gap pot 1 is unnecessary. The flowing through behavior can be varied and be affected by variation of the wire strength thus the cooling behavior of the wet-running pump. The invention relates to a bearing carrier (4) in the front region of a separating can (1) or separating pipe of a centrifugal pump facing the pump impeller, wherein the bushing-shaped bearing carrier is made exclusively of a pressed wire fabric surrounding the radial bearing (5) of the motor shaft as a filter ring. Bearing carrier (4) for a front area of a containment shell (1) or separating pipe of a centrifugal pump turned towards the impeller, characterised in that the bushing shaped bearing carrier (4) consists exclusively of a pressed wire mesh, which surrounds the radial bearing (5) of the engine shaft as a filter ring. Bearing carrier according to claim 1, characterised in that the wire mesh consists of stainless steel or sintered bronze. Bearing carrier according to claim 1 or 2, characterised in that it may be pressed into the front containment shell or separating pipe opening (2) without surrounding intermediate part(s). Bearing carrier according to one of the previous claims, characterised in that the radial bearing (5) may be pressed into it. Bearing carrier according to one of the previous claims, characterised in that it is shaped and compacted through a pressing process. Containment shell (1) or separating pipe of a centrifugal pump with a bearing carrier (4) according to one of the previous claims, characterised in that the bearing carrier (4) is in direct contact with the inner wall of the containment shell (1) or separating pipe with its external circumference.
