Cov qauv ntawv pov thawj
Daim ntawv pov thawj RoHS ua kom cov silicone O-rings tsis pub dawb los ntawm kev txwv cov sib txuas, thaum REACH ntawv pov thawj xyuas kom lawv ua tau raws li European cov qauv kev lag luam. ISO 9001 daim ntawv pov thawj ua kom muaj kev tswj hwm zoo, thaum daim ntawv pov thawj UL lees paub kev nyab xeeb hauv cov khoom siv hluav taws xob. NSF ntawv pov thawj xyuas kom silicone O-rings ua tau raws li National Sanitation Foundation cov qauv rau cov dej haus. Cov ntawv pov thawj no ua kom cov khoom muaj kev nyab xeeb thiab zoo.
Qhia
Lub tshuab nqus tsev vacuum o-ring yog ib lub foob muaj nyob rau hauv chav ntxhua khaub ncaws. Nyob rau hauv chav tsev ntxhua khaub ncaws, chav kub kub yog siv los muab cov nyhuv tu kom muaj zog, thaum O-ring ua raws li lub foob thiab tiv thaiv kom tsis txhob xau. O-rings yog tsim los ntawm silicone. Nws tau muab tso rau ntawm lub nozzle ntawm cov khoom siv ntxuav kom huv si kom ntseeg tau tias chav tsis xau lossis nkag mus rau hauv qhov chaw uas nws yuav tsum tsis txhob. O-ring kev ua tau zoo thiab kev ua tau zoo yog qhov tseem ceeb rau kev ua haujlwm kom raug ntawm cov khoom siv ntxuav. Yog li ntawd, thaum xaiv thiab hloov O-rings, nws raug nquahu kom siv cov khoom zoo O-rings uas ua tau raws li cov lus qhia tshwj xeeb los xyuas kom meej cov khoom ua haujlwm thiab kev nyab xeeb.
Qhov zoo
Lub tshuab nqus tsev vacuum o-ntiv nplhaib yog qhov tseem ceeb rau kev ruaj ntseg sealing hauv chav nozzles, cov kav dej, thiab cov li qub kom tiv thaiv kom tsis txhob tawg thiab lub zog poob. Nws qhov kub thiab txias tsis kam, tshuaj lom neeg tsis kam, hnav tsis kam, thiab hloov tau yooj yim ua rau nws xaiv qhov kev xaiv zoo rau cov tshuab ntxhua khaub ncaws. Lub o-ring lub peev xwm los tiv thaiv kev kub ntxhov thiab qhov kub thiab txias ua kom ruaj khov mus ntev thiab tiv thaiv dej thiab lub zog poob. Nws tus qauv tsim kuj tso cai rau kev saib xyuas sai, txo qis sijhawm thiab txhim kho kev ua haujlwm. Zuag qhia tag nrho, Chav tsev ntxhua khaub ncaws o-ring yog qhov tseem ceeb rau kev ntxuav kom huv.
