  Oberes Führungslager für Kaplanturbinen 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 
FührungslagersRingnuten 12 und 12a soll möglichst abgedichtet werden, weshalb das Lager gerade dort geringes Spiel haben soll. Deshalb wird erfindungsgemäss in diesem mittleren Lagerteil eine besondere   Ölzuführung   oder ein Ölkreislauf vorgesehen. Durch ein zweites Schmiersystem wird mit einer eigenen gesondert regelbaren Schmierölpumpe zusätzlich Schmieröl aus dem Reglerölbehälter angesaugt und einer zwischen den Ringnuten 12 und 20 angeordneten Ringnut 23 durch Leitungen 4 und 5 zugefUhrt, wodurch zusätzlich ein zweiter Kreislauf gebildet ist. Ein Thermometer 22 kontrolliert diesen gefährlichen Lagerteil. Beide Leitungen 4 und 5 können durch Ventile geregelt und dadurch diese Stelle auf richtiger Betriebstemperatur gehalten werden.

   Die Aufgabe dieses Lagerteiles, nämlich die Abdichtung der Öldruckkanäle 12 und 12a für den Servomotor und die Schmierung des mittleren Teiles des oberen FUhrungslagers durch einen getrennten   Druckölumlauf, wird   durch dieses System vollkommen erfüllt.

Guide bearing ring grooves 12 and 12a should be sealed as possible, which is why the bearing should have little play there. Therefore, according to the invention, a special oil feed or an oil circuit is provided in this central bearing part. By means of a second lubrication system with its own separately controllable lubricating oil pump, lubricating oil is additionally sucked in from the regulator oil container and fed to an annular groove 23 arranged between the annular grooves 12 and 20 through lines 4 and 5, whereby a second circuit is also formed. A thermometer 22 controls this dangerous storage part. Both lines 4 and 5 can be controlled by valves and thereby this point can be kept at the correct operating temperature.

   The task of this bearing part, namely the sealing of the oil pressure channels 12 and 12a for the servomotor and the lubrication of the middle part of the upper guide bearing by a separate pressure oil circulation, is completely fulfilled by this system.

PATENTANSPRUCH : Oberes Fuhrungslager für Kaplanturbinen, bei dem das auch als Lagerschmierung dienende Drucköl dem am oberen Ende der in der hohlen Turbinenwelle geführten Verstellstange angeordneten Servomotor Über zwei Ringnuten im Fuhrungslager und geeignet angeordnete Kanäle zugeführt wird, wobei zwischen den beiden Ringnuten eine dritte Ringnut angeordnet ist, die mit einem zweiten den gesondert regelbaren Abfluss des Lecköles bildenden Schmiersystem in Verbindung steht, dadurch gekennzeichnet, dass das zweite Schmiersystem eine eigene gesondert regelbare Schmierölpumpe aufweist, welche zusätzliches Schmieröl aus dem Reglerölbehälter ansaugt und über Kanäle (4 bzw. PATENT CLAIM: Upper guide bearing for Kaplan turbines, in which the pressure oil, which also serves as bearing lubrication, is fed to the servomotor located at the upper end of the adjusting rod guided in the hollow turbine shaft is connected to a second lubrication system which forms the separately controllable outflow of the leakage oil, characterized in that the second lubrication system has its own separately controllable lubricating oil pump which draws in additional lubricating oil from the regulator oil container and which is supplied via channels (4 or 5) der mittleren Ringnut (23) des Führungslager (2) mit regelbarem Druck zuführt, so dass die durch ein Thermometer (22) Uberwachte Lagertemperatur durch Regelung der zusätzlich zugefuhrten Schmiermenge gerade im kritischen mittleren Lagerbereiche einwandfrei beherrschbar ist. 5) feeds the central annular groove (23) of the guide bearing (2) with adjustable pressure so that the bearing temperature monitored by a thermometer (22) can be perfectly controlled by regulating the additional amount of lubricant supplied, especially in the critical central bearing area.
