Qhov zoo ntawm covcartridge mechanical foob's operation and the length of its life largely depend on the conditions of the equipment itself. Therefore, before installing the cartridge mechanical seal, careful inspection of the equipment will reduce the possibility of seal failure and maintenance costs. . The equipment must be checked from the following aspects:
1.Txoj kab uas hla thiab qhov tob ntawm lub tshuab foob kab noj hniav yuav tsum ua raws li qhov ntev ntawm lub foob sib dhos, qhov sib txawv dav dav yog±0.13 hli; qhov luaj li cas sib txawv ntawm lub ncej los yog bushing yog±0.03mm los yog±{{0}}00mm-0.05. Txheeb xyuas qhov axial runout ntawm ncej, tag nrho axial runout tsis tuaj yeem tshaj 0.25mm; Lub radial runout ntawm ncej yog kuaj, thiab radial runout ntawm ncej yog feem ntau tsawg tshaj li 0.05mm. Tshaj dhau radial runout tuaj yeem ua rau: hnav ntawm cov ncej lossis bushing; nce leakage ntawm qhov chaw sealing; nce kev vibration ntawm cov cuab yeej, yog li txo lub neej ntawm cov neeg kho tshuab foob.
2.Ncej curvature check. Qhov siab tshaj plaws curvature ntawm ncej yuav tsum tsawg dua {{0}}.07mm. Txheeb xyuas qhov khiav tawm ntawm cov kab noj hniav sealing, qhov khiav tawm ntawm cov kab noj hniav yuav tsum tsis pub tshaj 0.13mm. Yog hais tias qhov chaw ntawm lub seal kab noj hniav tsis perpendicular mus rau lub ncej, nws yuav ua rau ib tug series ntawm tsis ua hauj lwm ntawm lub tshuab foob. Vim lub sealing caj pas yog tsau rau ntawm lub sealing caj pas los ntawm bolts, kev co ntawm lub sealing kab noj hniav yog loj heev, uas ua rau lub installation ntawm lub caj pas inclined, uas nyob rau hauv lem ua rau lub inclination ntawm lub sealing zoo li qub nplhaib, uas ua rau tag nrho cov. foob kom co txawv txav, uas yog tshwm sim los ntawm fretting hnav. Qhov laj thawj tseem ceeb yog vim qhov hnav ntawm lub tshuab foob thiab cov khoom siv foob ntawm lub tog raj lossis lub tes tsho lub tes tsho tseem yuav nce ntxiv, thiab qhov txawv txav ntawm lub foob yuav ua rau hnav thiab qaug zog ntawm cov hlau bellows lossis kis tus pin, ua rau ntxov ntxov. tsis ua hauj lwm ntawm lub foob.
3.Txheeb xyuas qhov kev sib dhos ntawm lub qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob Misalignment ntawm lub seal kab noj hniav qhov thiab lub ncej yuav cuam tshuam lub dynamic load ntawm lub sealing nto, yog li shortening lub lag luam lub neej ntawm lub foob. Txhawm rau kho qhov chaw nruab nrab, qhov chaw nruab nrab zoo dua tuaj yeem tau txais los ntawm kev kho lub gasket ntawm lub taub hau twj tso kua mis thiab cov kabmob thav duab lossis rov ua dua qhov kev sib cuag.
