An end-face mechanical seal , or a mechanical end-face seal , also referred to as a mechanical face seal but usually simply as a mechanical seal , is a type of seal used in rotating equipment, such as pumps , mixers , blowers , and compressors. When a pump operates, the liquid could leak out of the pump between the rotating shaft and the stationary pump casing. Since the shaft rotates, preventing this leakage can be difficult.

Lubrication and Wear Characteristics of Mechanical Face Seals under Random Vibration Loading

The service life of mechanical face seals is related to the lubrication and wear characteristics. The stable analytical methods are commonly used, but they cannot address effects of random vibration loading, which, according to experimental studies, are important factors for lubrication and wear of mechanical face seals used in air and space vehicles. Hence, a dynamic model for mechanical face seals is proposed, with a focus on the effects of random vibration loading. The mechanical face seal in the axial direction is described as a mass-spring-damping system. Spectrum analysis specified for random vibration is then performed numerically to obtain the response power spectral density PSD of the mechanical face seal and calculate the root mean square RMS values under random vibration conditions. A lumped parameter model is then developed to examine how dynamic parameters such as stiffness and damping affect the lubrication regimes of mechanical face seals.

Мидж это как-нибудь переживет, - сказал он себе, усаживаясь за свой стол и приступая к просмотру остальных отчетов. Он не собирается выдавать ключи от директорского кабинета всякий раз, когда Мидж придет в голову очередная блажь. Не успел он приняться за чтение отчета службы безопасности, как его мысли были прерваны шумом голосов из соседней комнаты. Бринкерхофф отложил бумагу и подошел к двери. В приемной было темно, свет проникал только сквозь приоткрытую дверь кабинета Мидж.


Только мы трое. Было ужасно жарко. - И вы уверены, что эта женщина - проститутка. - Абсолютно.

Стратмор кивнул: - Как раз сейчас японские компании скачивают зашифрованную версию Цифровой крепости и пытаются ее взломать. С каждой минутой, уходящей на эти бесплодные попытки, ее цена растет. - Но это же абсурд, - не согласилась Сьюзан.

 - Полная незащищенность наступит максимум через пятнадцать минут.
