Q 4: Cov kev ceev faj rau kev siv yog dab tsi?
a) Lub valve yuav tsum xub xyuas seb lub valve puas zoo thiab cov khoom siv ua tiav.
b) Lub valve yuav tsum tau ua kom huv si thiab khaws cia hauv chav qhuav thiab tiv thaiv kev vibrations.
c) Thaum lub valve tsis siv rau kev cia ntev, lub valve yuav tsum nyob rau hauv lub micro-qhib lub xeev thiab yuav tsum tau soj ntsuam tsis tu ncua kom tsis txhob ya raws, xeb thiab kev laus ntawm cov roj hmab qhov chaw.
d) Ua ntej kev teeb tsa, qhov chaw ntawm lub valve thiab lub tshuab nqus tsev yuav tsum raug ntxuav raws li kev xav tau ntawm lub tshuab nqus tsev.
e) Tus neeg siv lub flange txuas nrog lub valve yuav tsum tsis muaj qhov sib txuas hauv qhov sib koom ua ke.
Q5: Dab tsi yog qhov ua tsis tiav thiab yuav tshem tawm lawv li cas?
Failures Yog vim li cas txoj kev
Tsis zoo sealing Roj stains adheres rau lub sealing nto.ntxuav cov av.
khawb ntawm qhov chaw sealing.Tshem tawm khawb los ntawm polishing ntawv lossis tshuab cuab yeej.
Roj hmab foob puas Hloov cov roj hmab foob.
Kev puas tsuaj Flexible Hoses Hloov lossis kho-welded.
