<p>The method involves temporarily arranging a liquid plates (16,18,20) and other liquid plates (17,19,21) on the housing walls (78-83). The local circulation of the liquid from the plates (16-21) is performed in the direction of the plates (114,116,118,120,122,124). The potentially higher centrifugal forces are provided by design measures in the central peripheral areas of the plates. The large change in pressure conditions is occurred, when specific pressure greater than the preset pressure. The pressure equalization is carried out in the direction of the gas-fixed seals (1-3). The liquid closes the temporary gas connection, when the pressure escapes into environment outside of the gas-fixed seal with the low pressure. The temporary breakdown of the gas from the portion in the gas-fixed seal is occurred, when the liquid is locally arranged, and the gas connection is freed, such that the high pressure is prevailed outside of the gas-fixed seal. An individual gas-fixed seals are cascaded to each other. An independent claim is included for device for switching gas-fixed seal e.g. shaft seal for withstanding high pressure at shaft bushings.</p> |
