Rotating Pump and Securing Plate

Abstract

In a rotating pump having at least one driven conveying element which is arranged in a product space, flowed through by the product to be conveyed, and is driven by means of a shaft which protrudes into the product space from the outside, the shaft being sealed with respect to a wall of the product space, the seal is configured as a slide ring seal to be mounted on the product side with an outer positively locking positional securing means.

What is claimed is: 
     
         1 . A rotating pump having at least one driven conveying element which is arranged in a product space, flowed through by a product to be conveyed, and is driven by means of a shaft which protrudes into the product space from outside, the shaft being sealed with respect to a wall of the product space, wherein the seal is configured as a slide ring seal to be mounted on the product side with an outer positively locking positional securing means, the positional securing means being configured to prevent both rotational movement of the slide ring seal and axial movement of the slide ring seal towards the product space. 
     
     
         2 . The pump according to  claim 1 , wherein the slide ring seal has a first rotating section, a second rotating section and a stationary section. 
     
     
         3 . The pump according to  claim 2 , wherein the stationary section comprises a sleeve which is inserted into a seal seat in the wall. 
     
     
         4 . The pump according to  claim 3 , wherein the sleeve protrudes out of he wall on the side which faces away from the product space. 
     
     
         5 . The pump according to  claim 4 , wherein the sleeve has a circumferential groove on the section which protrudes out of the wall. 
     
     
         6 . The pump according to  claim 5 , wherein the positional securing means is configured as a securing plate which engages laterally around the sleeve and in the process engages into the groove. 
     
     
         7 . The pump according to  claim 6 , wherein the securing plate engages into the groove on a circumferential angle of more than 180°. 
     
     
         8 . The pump according to  claim 6 , wherein the securing plate has lateral fingers which, when engaging around the sleeve, are first of all bent outwards elastically and subsequently spring back in the direction of their rest position. 
     
     
         9 . The pump according to  claim 5 , wherein the sleeve has a milled-out section which adjoins the groove. 
     
     
         10 . The pump according to  claim 6 , wherein the sleeve has a milled-out section which adjoins the groove. 
     
     
         11 . The pump according to  claim 9 , wherein the positional securing means is configured as a securing plate that has a projection which engages as an anti-rotation safeguard into the milled-out section. 
     
     
         12 . The pump according to  claim 10 , wherein the securing plate has a projection which engages as an anti-rotation safeguard into the milled-out section 
     
     
         13 . The pump according to  claim 6 , wherein the securing plate is arranged in a leakage space between the product space and a drive section of the pump, and in that the securing plate is bent over at an end which does not interact with the sleeve, in order to provide a protective hand guard for the leakage space. 
     
     
         14 . The pump according to  claim 6  wherein the securing plate is fixed by way of one or more securing bolts. 
     
     
         15 . A securing plate of a pump according to  claim 6 , wherein the securing plate has a projection which is adapted to engage as an anti-rotation safeguard into a milled-out section of a sleeve inserted into a seal seat in a wall of a product space of the pump. 
     
     
         16 . The securing plate of  claim 15 , wherein the securing plate has lateral fingers which, when engaging around the sleeve, are first bent outwards elastically and subsequently spring back in the direction of their rest position. 
     
     
         17 . The securing plate of  claim 15 , wherein the securing plate is adapted to be arranged in a leakage space between the product space and a drive section of the pump. 
     
     
         18 . The securing plate of  claim 17 , wherein the securing plate is bent over an end which does not interact with the sleeve to provide a protective hand guard for the leakage space. 
     
     
         19 . The securing plate of  claim 15 , wherein the securing plate is adapted to be fixed by way of one or more securing bolts.
