Die PSS Wellendichtung Typ B ist eine mechanische Gleitringdichtung. Die Dichtfläche entsteht zwischen den ebenen Flächen des rotierenden Edelstahlrotors und dem stationären Kohleflansch.Der stationäre Kohleflansch wird mit Schlauchklemmen an der Vorderseite des Balges und das hintere Ende des Balges über das Sternrohr befestigt und wird mit Schlauchklemmen gesichert. Der Edelstahlrotor ist auf der Welle vor dem Kohleflansch montiert. Der Edelstahlrotor wird verwendet, um den Balg zu komprimieren, bevor der Rotor mit Stellschrauben an der Welle befestigt wird. Diese Kompression (Vorspannung) sorgt für einen konstanten Kontakt zwischen den beiden flachen Seiten des Edelstahlrotors und des Kohleflansches. Dadurch kann die PSS Wellenabdichtung die variable Vorwärts- und Rückwärtsbewegung - bedingt durch den Propellerschub - ausgleichen. Der Kohlenstoffflansch ist zum Wellendurchmesser überbohrt, so dass er um die Welle herum 'schwimmen' kann und somit die meisten Fehlausrichtungs- und Schwingungsprobleme ausgleicht. Der Rotor aus rostfreiem Stahl ist durch zwei O-Ringe, die in die Bohrung des Kragens eingelassen sind, gegen die Welle abgedichtet. Diese O-Ringe rotieren mit der Welle und dem Edelstahlrotor und unterliegen keinem Verschleiß während des Betriebs.

Misses some important context, but a solid book
Format: Audiobook
I can't give it the 3.5 stars it deserves. Smith is an outstanding writer and has long view China as an adversary that we intentionally do not pay attention to given the elites make large amounts of money working with the CCP. In this book he demonstrates that happened from the get go, starting with Kissinger. Rarely, if ever, were American interests ever viewed as the lens with which to see China, only as a way to make money for power brokers and businesses alike. He points to Trumps long standing opposition to the way the international trade system evolved and the way it harmed middle class Americans.
All of this is outstanding, but the book loses many points trying to cover for terrible protectionist economic policies. We certainly may have gone too far in hollowing out the industrial base, but 100% of Americans benefitted from lower price and more selections. It is not the purpose of the book, but a look at overall US business policy has been to harm Amercians, one need look no further than mass immigration, legal and illegal that drive down wages at the lower/middle end. Nor does the book bother with looking at general business mindless following each other for yet another new fad, from six sigma to who moved my cheese. Again, not what the book is about, but he tries to make the claim that all of this is China and elite policy driving toward this outcome when that data is not supported.
Overall, it is a better than worse book that one should read if for no other reason than to see how far we have actually bent over for China for gains that are mostly illusory for business access. That China still uses the elites to gain access not just to markets but US citizen minds is the real problem. Smith does a good job pointing that out

Yet, so many US consumers take a knee to Chinese imports.
Format: Kindle
My first response to Lee Smith's "The Chinese Matrix" is anger with the CCP. But, they did what treasonous US politicians and investors permitted in exchange for wealth and power. The current situation reminds me of the Chinese finger trap - a small tube of woven reeds just large enough to insert a finger into each end. When naturally trying to withdraw the fingers from opposite ends, the woven reeds constricted. Escape was contrary to natural instinct. Likewise, to extract our country from the Chinese Matrix will require unnatural sacrifice.

Comprehensive and bold analysis of US foreign policy with China.
Format: Kindle
Lee Smith takes the reader through the many years of China appeasement from Kissenger and Nixon to the present where China continues to suck the power of the US toward its goal of global domination.
