Description

Gleitringdichtung mit Sperrflässigkeit Gegenstand der Neuerung ist ein Kreislaufsystem fdr die Jperr- flusi. igkeit von doppeltwirkenden c'leitringdichtu. ngeri. ijei den bisherigen Kreisläufen t'r jie perrfidssikeit von ,-, oppelwellendiel-itungen war es üblich, die Sperrfidsuigkeit durch eine Hochdruckpumpe m. it großem ördervolumen Au. f den g<=- wunsohten Jporrdruck zu bringen und in den Jperraum der Doppei- ellendichtung u. presaen. Beim Austritt aus desi Sperram Vt'u. r- de die Jperrfliissigkei t durch eine Drossel du-f den Annanedru-ck der Hochdrtickptimpe entspannt und anschließend gekühlt.

Gemäß der Neuerung wird vorgeschlagen, den Kreislauf der Jperr- fissigkeit aufzutrennen, einmal in das Uswalzen der Flassiß- keit und zwn anderen in das Nachpampen der aus der Dichtung aus, tretenden Leckmenge. Hierdurch ist es möglich, einen in sich geschlossenen Hochdrckkreislauf mit 3perraum (2) uriù. il ra (4) zu verwenden. Eine zugehörige Hochdrckpumpe (5) fördert sJperrflU, ssigkeit in diesen Hochdrokkreisla&f. Ihre Pörderuene istetw&s großer ais die an der Doppldiohtung (1) auftretende i-eckengo. Der berschß der in den ochdru. ckkreialau. f geför- derten derten ßperrfltis. idgkeit tritt durch ein Vorspannventil (6), welches den Druck is Hochdruckkreislau. f bestimmt, wieder in denAnsagbehälter (S) der Hoohdrackpu. mpe auräck. Der Vorteil dieser Anordnung besteht darin, daß die ilochdruckpt. uBpe (5) nur L'Ur eine kleine engenleistung aasgebildet werden nm, und daß Größe, Preis and Antriebsleistang dementsprechend klein sind. Die Kreislaufbewegu. ng der operrfi ssieit im Hochdruckkreis- lau. f knn drch den Temperaturunterschied selbsttätig gesche- heu, oder es kann in einer weiteren Au. sbildung der Erfindung <Z eine besondere Umwälzpumpe (3) vorgesehen werden. Diese Um- wälaipampe braucht nur die Reibungsverluste der SperrflUssig- keit itn Hochdruckkreislasif {iberwinden ond knn deshalb eben- falls klein und einfach aufgebaut sein. hefter ist es möglich die Umwälzpumpe (5) von der abzudich- tenden ? elle antreiben zu lassen. Das ist deshalb möglich, weil eine Kdhiu. ng der Sperrflüssigkeit nur bei laufender el- lendichtung notwendig ist. Hierdurch'wird ein besonderer ln- triebstnotor fr diu Umwälzpumpe eingespart. , ist au. oh denkbar, die älpcuRpe (3) mit der Dichtung (2) baulich zu vereinigen, z. ß. dadurch, da3 n der absudichten- den elle Srderfidel angebracht werden. ies bringt eine weitere Vereinfachung der Anlage mit sich. '-'. beno kRD. fa. a. D die Umwälzpumpe und ie fiochdruckppe zu. sam- en. buu. en, das reialaafayste noch eicr za vereinfachen. / - uin besonderer Vorteil ergibt sich, wenn das Vorspannventil (6) von Druck des abzudichtenden Raumes (9) gesteuert wird. hierbei setzt das Vorspannventil (6) den Hochdruckkreialatif erst dann unter Druck, wenn im abzudichtenden Raum (9) ein Überdruck herrscht, und der Druck im Hochdruckkreislauf un- terscheidet sich imaer selbsttätig am ein vorbestimmtes aß vo ! B. Dru. ck iu. abzudichtenden Ra. u. . Das bringt die großen Vor- teile mit. sich, daß ein"'bertreten von SperrflU-ssigkeit in denabzudichtenden Raum, was bei unsachgemSBer Bedienn auf- treten konnte, Nit Sicherheit vermieden wird, daß die Bedie- naiig des Vorspannventil (6) überflüssig wird und daß während der Zeit, in der im K. aum (9) kein Jberdru. ck herracht, die 1'ochdru. ckpa. pe (5) it geringer-ueistung und geringer Abnt- CD zunglaafen kann. Mechanical seal with barrier fluid The object of the innovation is a circulatory system for the flusi. ity of double-acting mechanical seal. ngeri. ijei the previous cycles t'r jie perrfidssikeit of , -, oppelwellendiel-itungen, it was common to use the Sperrfidsuigkeit by means of a high pressure pump with a large delivery volume Au. f den g <= - we would like to bring pressure to the table and put it in the open space of the double ellendichtung and presaen. Upon leaving desi Sperram Vt'u. r- de-the blocking fluid through a throttle du-f the annane pressure the high pressure pulse relaxed and then cooled. At the- ssla procedure needed! n a high-pressure pump with a large volu. metit) and dtimit great power, eil the Fdrderene ier possibly due to the blocking capacity a. baf! her <bundle. egg ngawars of the op- pel shaft seal ng must correspond. 3. According to the innovation, it is proposed that the cycle of locking to separate fissure, once in the rolling of the Flassiss- speed and between others in the postponing of the poetry from, leaking leakage. This makes it possible to have one in itself closed high pressure circuit with 3perraum (2) uriù. il ra (4) to use. An associated high-pressure pump (5) promotes Locking fluid in these high-pressure circuits. Your Pörderuene Isetw & s greater than that occurring at the double wire (1) i-eckengo. The excess in the ochdru. ckkreialau. f promoted changed derten ßperrfltis. equilibrium occurs through a preload valve (6), which the pressure is high pressure circuit. f determined to be back in the announcement container (S) of the Hoohdrackpu. mpe auräck. The advantage this arrangement consists in that the hypertension. uBpe (5) only a small narrow performance can be formed nm, and that size, price and power output accordingly are small. The circulatory movement ng the operrfi ssieit in the high pressure circuit lukewarm. f the temperature difference can occur automatically hay, or it can be in another Au. formation of the invention <Z a special circulation pump (3) can be provided. This order Wälaipampe only needs the frictional losses of the barrier fluid The ability to overcome high pressure cycle lasers and can therefore also if small and simply constructed. it is possible to close the circulation pump (5) from the tendency? to let elle drive. That is why it is possible because a kdhiu. of the sealing liquid only when the elec- oil seal is necessary. This creates a special interior Drive motor for the circulating pump saved. , is au. oh conceivable, the älpcuRpe (3) with the seal (2) to be structurally united, e.g. ß. by the fact that the sealing the elle Srderfidel are attached. his brings one further simplification of the plant with itself.

B. Dru. ck iu. Ra to be sealed. u. That brings the great advantages share with. that a "'trespassing of barrier fluid in the room to be sealed, which could result in improper use could occur, Nit security is avoided that the operator naiig of the preload valve (6) becomes superfluous and that during the time in which no jberdru. ck that 1'ochdru. ckpa. pe (5) with low performance and low dis- CD zunglaafen can.
