PVC eeb clampsyog dav siv rau cov ceg sib txuas ntawm cov kav dej loj hauv cov dej, dej, kev ua tshuaj, thiab kev siv dej. Thaum lub sij hawm siv tiag tiag, teeb meem xws li to, tawg, los yog bolt loosening yuav tshwm sim vim kev txhim kho tsis raug, cov khoom laus, lossis kev hloov pauv hauv kev ua haujlwm. Cov hauv qab no yog cov teeb meem tshwm sim thiab lawv cov kev daws teeb meem zoo sib xws.
1. Tawm ntawm qhov txuas
Qhov teeb meem no yog tus cwj pwm los ntawm cov tee dej los yog txuas txuas ntxiv ntawm qhov chaw sib cuag ntawm lub eeb clamp thiab cov yeeb nkab loj. Cov laj thawj tseem ceeb muaj xws li kev teeb tsa tsis raug lossis kev hloov pauv / kev puas tsuaj ntawm lub gasket, qhov tsis sib xws lossis khawb sab nrauv ntawm cov yeeb nkab loj nrog cov kab mob sib kis, thiab tsis txaus lossis tsis sib xws ntawm cov ntsia hlau nruj nruj. Cov kev daws teeb meem muaj xws li: disassembled thiab tshuaj xyuas lub gasket rau kev ncaj ncees thiab hloov nws yog tias tsim nyog, ntxuav lub sab nrauv ntawm lub ntsiab yeeb nkab kom tshem tawm cov roj, av, thiab burrs, nruj bolts tusyees nyob rau hauv ib tug ntoo khaub lig qauv rau lub torque, thiab ua ib tug hydrostatic siab test tom qab installation kom paub meej tias tsis muaj leakage ua ntej muab lub kaw lus rau kev pab.
2. Kev tawg ntawm lub cev Clamp
Qhov teeb meem no yog tus cwj pwm los ntawm pom cov kab nrib pleb ntawm lub eeb clamp lub cev, uas tuaj yeem ua rau tawg hauv qhov mob hnyav. Cov laj thawj tseem ceeb suav nrog ntau dua - nruj ntawm cov bolts uas ua rau muaj kev ntxhov siab hauv cheeb tsam, qhov ntsuas kub qis qis txo qhov tawv ntawm cov khoom siv PVC, kev hloov pauv siab hauv cov kav dej ntau dhau ntawm cov khoom ntsuas qhov ntsuas siab, thiab lub sij hawm raug rau ultraviolet hluav taws xob los yog corrosive chemical ib puag ncig. Cov kev daws teeb meem suav nrog: siv lub torque ciaj ntswj kom nruj bolts rau tus nqi teev kom tsis txhob dhau - zawm, tsis txhob cuam tshuam los yog yuam kev sib dhos thaum tsim kho hauv qhov chaw qis - qhov kub thiab txias, paub meej tias lub zog ua haujlwm siab sib tweeb clamp's rated siab, thiab siv UV tiv thaiv lossis tiv thaiv kev ntsuas rau kev teeb tsa sab nraum zoov, lossis xaiv UV- cov ntaub ntawv tiv thaiv.
3. Bolt Loosening lossis Corrosion
Qhov teeb meem no yog tus cwj pwm los ntawm kev hnov ntxhiab ntawm bolts tom qab lub sijhawm ua haujlwm lossis xeb ntawm cov hlau bolts. Cov laj thawj tseem ceeb suav nrog kev vibration lossis siab pulsation hauv cov kav dej ua rau nws tus kheej - xoob ntawm cov xov, tsis siv cov tshuab ntxhua khaub ncaws lossis xauv cov txiv ntoo, thiab qhov sib txawv ntawm thermal expansion coefficients ntawm cov hlau bolts thiab cov khoom siv PVC. Cov kev daws teeb meem suav nrog: xaiv cov txiv ntseej nrog lub xauv tsim los yog siv xov- xauv qhov sib txuas, ua cov kev tshuaj xyuas tsis tu ncua thiab rov- zawm bolts txhua rau lub hlis, thiab siv cov ntsia hlau stainless hauv qhov chaw ntub lossis corrosive.
4. Kev ua tsis ncaj ntawm lub qhov taub
Qhov teeb meem no yog tshwm sim los ntawm misalignment ntawm lub qhov drilled nyob rau hauv lub ntsiab yeeb nkab thiab lub eeb clamp qhov hluav taws xob, cuam tshuam rau ceg yeeb nkab txuas. Cov laj thawj tseem ceeb suav nrog kev ntsuas tsis raug thiab qhov chaw ua ntej drilling, thiab laum me ntsis slippage thaum lub sij hawm drilling. Cov kev daws teeb meem muaj xws li: kos tus ntoo khaub lig-centerlines ntawm cov yeeb nkab loj ua ntej drilling, siv lub hauv paus punch lossis pilot laum los pab pib, me ntsis kho lub kaum sab xis ntawm lub installation.lub eeb clampyog hais tias qhov misalignment yog me me, thiab hloov cov yeeb nkab seem los yog siv ib tug txo coupling los them yog tias qhov misalignment yog hnyav heev.
5. Kev laus ntawm Gasket
Qhov teeb meem no yog tshwm sim los ntawm hardening, tawg, los yog poob ntawm elasticity ntawm gasket tom qab siv ntev -, ua rau to. Cov laj thawj tseem ceeb suav nrog cov khoom siv gasket tsis tsim nyog rau qhov kev pabcuam nruab nrab lossis qhov kub thiab txias, thiab dhau lub neej ua haujlwm. Cov kev daws teeb meem suav nrog: xaiv cov ntaub ntawv gasket tiv taus qhov nruab nrab corrosion, thiab ua haujlwm tiv thaiv kev hloov raws li lub sijhawm pom zoo, feem ntau txhua txhua 3 mus rau 5 xyoos.
