Yuav ua li cas khiav lag luam thiab tswj lub valve thaum lub sijhawm ua haujlwm, thiab cov kev cai dab tsi yuav tsum ua haujlwm thiab tu lub valve ua raws li

Yuav ua li cas khiav lag luam thiab tswj lub valve thaum lub sijhawm ua haujlwm, thiab cov kev cai dab tsi yuav tsum ua haujlwm thiab kev saib xyuas ntawm lub valve ua raws li ntau tus kws ua haujlwm hydraulic muaj kev txawj ntse hauv kev tu txhua hnub ntawm lub valve hauv kev ua haujlwm, thiab yuav luag tsis muaj qhov yuam kev, tab sis lawv feem ntau tsis quav ntsej txog cov teeb meem tshwm sim ntawm lub valve hauv cov txheej txheem ua haujlwm. Yuav ua li cas khiav lag luam thiab tswj lub valve hauv cov txheej txheem ua haujlwm? Cov kev cai dab tsi yuav tsum tau ua thiab kev saib xyuas ntawm cov li qub? Zoo li valve teb lawv ib tug los ntawm ib tug! 1 、 Yuav ua li cas khiav lag luam thiab tswj lub valve thaum lub sijhawm ua haujlwm ① Khaws sab nrauv thiab txav qhov chaw ntawm lub valve kom huv si thiab tiv thaiv kev ncaj ncees ntawm cov xim valve. Lub trapezoidal xov, qia txiv ntoo, txhawb zawv zawg qhov chaw, iav, worm thiab lwm qhov chaw ntawm lub valve nto, qia thiab qia txiv ntoo yog ib qho yooj yim rau deposit ib tug loj npaum li cas ntawm plua plav, roj stain, nruab nrab residue thiab lwm yam av, ua rau hnav thiab corrosion. lub valve. Yog li ntawd, khaws lub valve kom huv si txhua lub sijhawm. Cov plua plav dav dav ntawm lub valve yog tsim rau txhuam tu thiab compressed cua tu, txawm tias tooj liab txhuam txhuam kom txog thaum lub tshuab ua kom pom cov xim hlau, thiab cov xim pleev xim rau cov xim tiag tiag ntawm cov xim. Lub tshuab nqus tsev vacuum yuav tsum nyob rau hauv tus neeg saib xyuas tshwj xeeb thiab tshuaj xyuas tsawg kawg ib zaug ua haujlwm; Qhib lub qhov dej ntws tawm thiab lub tshuab nqus dej tsis tu ncua, lossis tshem tawm thiab yaug kom tsis txhob muaj av thaiv lub valve. ② Khaws lub valve lubrication, valve ntaiv xov, valve qia txiv ntoo thiab kev txhawb nqa zawv zawg qhov chaw, bearing txoj hauj lwm, iav thiab cab meshing qhov chaw thiab lwm yam khoom sib txuam. Cov txheej txheem lubrication zoo yuav tsum tau txo qis kev sib txhuam thiab zam kev sib tsoo. Rau qhov chaw uas tsis muaj roj khob lossis lub taub hau uas yooj yim rau kev puas tsuaj lossis poob thaum lub sijhawm ua haujlwm, tag nrho cov tshuab lubrication yuav tsum tau kho kom ntseeg tau tias cov roj hluav taws xob ua haujlwm. Lub lubrication ib feem yuav tsum tau sau tsis tu ncua raws li qhov xwm txheej tshwj xeeb. Yog tias nws feem ntau qhib, qhov kub thiab txias valve yog tsim rau refueling ib lub lim tiam mus rau ib hlis; Yog tias nws tsis tau qhib ntau zaus, lub voj voog refueling ntawm qhov qis-kub valve tuaj yeem ntev dua. Lubricants muaj xws li roj, butter, molybdenum disulfide thiab graphite. Cov roj cav tsis haum rau lub siab kub li qub; Butter tsis haum ib yam. Nws yuav ploj vim yog melting ntawm qhov kub thiab txias. Lub siab kub valve yog tsim rau ntxiv molybdenum disulfide thiab so graphite hmoov. Yog hais tias cov khoom uas raug lubricating, xws li trapezoidal threads, nruab nrab ntawm cov hniav, thiab lwm yam, yog siv roj, lawv yooj yim rau polluted los ntawm plua plav. Yog tias molybdenum disulfide thiab graphite hmoov siv rau lubrication, nws tsis yooj yim rau cov plua plav paug, thiab cov nyhuv lubrication zoo dua li butter. Graphite hmoov tsis yooj yim rau kev thov ncaj qha. Nws tuaj yeem muab sib xyaw rau hauv cov tshuaj txhuam nrog me ntsis roj lossis dej. Lub ntsaws valve yuav tsum tau ntim cov roj thaum lub sij hawm teev, txwv tsis pub nws yog ib qho yooj yim mus hnav thiab to. ③ Khaws ob daim ntawv kom zoo. Lub bolts ntawm flange thiab kev txhawb nqa yuav tsum zoo thiab yuav tsum tsis txhob xoob. Yog hais tias lub fastening txiv ntseej ntawm tes log yog xoob, nws yuav tsum tau nruj me ntsis nyob rau hauv lub sij hawm kom tsis txhob hnav lub sib koom tes los yog poob lub tes log. Lub tes log yuav tsum tsis txhob poob thiab hloov raws sijhawm. Lub packing sib txawv siab yuav tsum tsis txhob inclined los yog tsis muaj preload clearance. Nyob rau hauv ib puag ncig yooj yim polluted los ntawm nag, daus, plua plav, thiab lwm yam, lub valve pas nrig yuav tsum tau nruab nrog ib tug tiv thaiv npog. Tus kav ntawm lub valve yuav tsum ua kom tiav thiab raug. Cov hlau lead foob, npog thiab pneumatic accessories ntawm lub valve yuav tsum tsis muaj zog. Lub tsho insulating yuav tsum tsis muaj kev nyuaj siab thiab tawg. Tsis tas li ntawd, nws tsis raug tso cai rau khob lub valve, txhawb nqa cov khoom hnyav lossis cov neeg ua haujlwm sawv ntsug kom tsis txhob fouling lub valve thiab ua rau lub valve puas. Tshwj xeeb, tsis yog-hlau mesh thiab cam khwb cia hlau li qub raug txwv. Tswj xyuas cov khoom siv hluav taws xob txhua hnub. Kev saib xyuas cov khoom siv hluav taws xob feem ntau tsis pub tsawg dua ib hlis ib zaug. Cov ntsiab lus ntawm kev saib xyuas muaj xws li: qhov zoo li yuav tsum huv si yam tsis muaj plua plav, thiab cov khoom siv yuav tsum tsis txhob muaj kuab paug los ntawm chav dej, dej thiab roj; Lub sealing nto thiab cov ntsiab lus yuav tsum ruaj thiab nruj. Tsis muaj dej; Lub lubricating qhov yuav tsum tau ntim nrog roj raws li cov kev cai, thiab lub valve txiv ntseej yuav tsum tau sau nrog roj; Qhov hluav taws xob yuav tsum tsis muaj qhov tsis ua haujlwm tsis zoo, qhov hloov pauv tsis siv neeg thiab thermal relay yuav tsum tsis txhob buckled, thiab qhov taw qhia lub teeb yuav tsum tau muab tso rau kom raug. 2 、 Cov kev cai dab tsi yuav tsum ua haujlwm thiab kev saib xyuas cov li qub raws li Kev saib xyuas thiab kev tswj xyuas cov li qub yuav tsum ua raws li cov kev cai hauv qab no: 1. Lub koom haum solenoid valve ntawm cov nag hav zoov valve yuav tsum raug tshuaj xyuas txhua lub hlis thiab yuav tsum tau pib ua haujlwm. xeem. Yog tias qhov kev txiav txim yog qhov txawv txav, nws yuav tsum tau hloov raws sijhawm; 2. Cov khoom siv hluav taws xob thiab qhib thiab kaw kev ua haujlwm ntawm hluav taws xob valve thiab solenoid valve yuav tsum raug kuaj txhua lub hlis; 3. Tag nrho cov tswj li qub nyob rau hauv lub system yuav tsum tau kho nyob rau hauv lub qhib los yog teev nyob rau hauv lub xeev nrog cov hlau lead seals los yog chains. Cov hlau nplaum thiab cov hlua khi yuav tsum tau tshuaj xyuas ib hlis ib zaug. Thaum muaj kev puas tsuaj lossis kev puas tsuaj, lawv yuav tsum tau kho thiab hloov raws sijhawm; 4. Lub valve tswj nyob rau hauv lub qhov dej sab nraum zoov thiab nyob rau hauv cov dej inlet yeeb nkab yuav tsum tau soj ntsuam ib zaug ib lub hlis twg, thiab nws yuav tsum xyuas kom meej tias nws yog tag nrho qhib; 5. Cov tsos ntawm cov dej tswj valve thiab lub tswb valve pawg yuav tsum raug tshuaj xyuas txhua hnub, thiab lub kaw lus yuav tsum nyob rau hauv lub xeev tsis muaj txhaum; 6. Kev kuaj dej tawm yuav tsum tau ua rau txhua qhov kawg ntawm qhov ntsuas dej thiab qhov ntsuas dej tawm ntawm lub tswb valve ntawm lub kaw lus txhua lub hlis twg, thiab seb lub kaw lus pib, lub tswb ua haujlwm thiab qhov hluav taws xob qhov hluav taws xob zoo li qub yuav tsum raug kuaj xyuas; 7. Thaum lub qhov dej hauv lub nroog qhib tag nrho, qhov sib txawv ntawm qhov sib txawv ntawm qhov rov qab tiv thaiv yuav tsum tau sim txhua lub hlis, thiab yuav tsum ua raws li cov kev cai ntawm lub teb chaws tam sim no cov qauv: siab txo backflow inhibiter GB / T 25178, tsis tshua muaj kev tiv thaiv backflow. inhibiter JB / T 11151 thiab ob daim tshev valve backflow inhibiter CJ / T 160.
