Mounting disc is it rotate valve stem , guarantee records of pressure that root
being packed reach the above giving a recommendation value constantly to want at

pigeonholes , so as to ensure the pressure of packing of a root.

To the best pressure that a root packs of the pump:
To pack pressure (Pi )1 , medium of working pressure generally sealed records of root of letter of pump. 5-2 times, but pi, still with a lot of factors, the structure like the pump in fact, the situation of the sealed letter, medium temperature, viscidity,etc. have something to do, decision this pi need in scene according to actual working condition and make, in order to guarantee sealing property of pump fully. In the mounting disc root, must be careful, after putting a root well, must start the pump , then could begin to seal the bolt that the letter pigeonholed closely slowly , until the fact that pump does not leak, observe one minute, can urgent half a nut so as to ensure and seal according to situation.
