Momwe mungagwiritsire ntchito ndi kusunga valavu panthawi yogwira ntchito, ndi malamulo otani omwe akuyenera kutsatiridwa ndi kayendetsedwe ka valve

Akatswiri opanga ma hydraulic ambiri ali ndi luso pakusamalira tsiku ndi tsikuvalavu pogwira ntchito, ndipo palibe zolakwika, koma nthawi zambiri amanyalanyaza mavuto omwe angakhalepo a valve pakugwira ntchito. Momwe mungagwiritsire ntchito ndikusamalira valavu pakugwira ntchito? Ndi malamulo otani omwe kagwiritsidwe ntchito ndi kukonza mavavu ayenera kutsatira? Monga valavu amawayankha mmodzimmodzi!

1,Momwe mungagwiritsire ntchito ndi kusamalira valavu panthawi yogwira ntchito

① Sungani mbali zakunja ndi zosuntha za valve zoyera ndikuteteza kukhulupirika kwa utoto wa valve. Ulusi wa trapezoidal, mtedza wa tsinde, zida zothandizira, zida, nyongolotsi ndi mbali zina pamtunda wa valve, tsinde ndi mtedza wa tsinde ndizosavuta kuyika fumbi lalikulu, utoto wamafuta, zotsalira zapakati ndi dothi lina, zomwe zimapangitsa kuti pakhale dzimbiri komanso dzimbiri. valavu.

Choncho, sungani valavu yoyera nthawi zonse. Fumbi lambiri pa valavu ndiloyenera kuyeretsa burashi ndi kuyeretsa mpweya, ngakhale ndi burashi ya waya yamkuwa mpaka malo opangidwa ndi makina akuwonetsa zitsulo zonyezimira, ndipo utoto wa utoto umasonyeza mtundu weniweni wa utoto.

Msampha wa nthunzi uyenera kuyang'aniridwa ndi munthu wopatsidwa ntchito yapadera ndikuwunikiridwa kamodzi pakusintha; Tsegulani valavu yothamangitsira ndi msampha wa nthunzi nthawi zonse, kapena sungunulani ndikutsuka pafupipafupi kuti mupewe dothi lomwe lingatseke valavu.

② Sungani zokometsera za ma valve, ulusi wa makwerero a valve, nthiti ya valavu ndi mbali zotsetsereka, malo otsetsereka, zida ndi ma meshing a mphutsi ndi zina zofananira zosuntha. Kupaka bwino kumafunika kuti muchepetse mikangano komanso kupewa kuvala. Pazigawo zopanda kapu yamafuta kapena nozzles zomwe ndizosavuta kuwonongeka kapena kutayika pakagwira ntchito, makina onse opaka mafuta amayenera kukonzedwa kuti awonetsetse kuti mafuta akuwotcha.

Gawo lopaka mafuta lidzadzazidwa nthawi zonse malinga ndi momwe zinthu zilili. Ngati nthawi zambiri imatsegulidwa, valavu yotentha kwambiri ndi yoyenera kuwonjezereka kamodzi pa sabata mpaka mwezi; Ngati sichitsegulidwa kawirikawiri, kuthamanga kwa mafuta kwa valve yotsika kutentha kungakhale yaitali. Mafuta amaphatikizapo mafuta, batala, molybdenum disulfide ndi graphite. Mafuta a injini sali oyenerera ma valve otentha kwambiri; Batala nawonso siwoyenera. Idzatayika chifukwa cha kusungunuka kwa kutentha kwakukulu. Vavu yotentha kwambiri ndiyoyenera kuwonjezera molybdenum disulfide ndikupukuta ufa wa graphite.

Ngati mbali zowonekera zopangira mafuta, monga ulusi wa trapezoidal, pakati pa mano, ndi zina zotero, zimagwiritsidwa ntchito ndi mafuta, zimakhala zosavuta kuipitsidwa ndi fumbi. Ngati molybdenum disulfide ndi graphite ufa amagwiritsidwa ntchito popaka mafuta, sikophweka kuipitsidwa ndi fumbi, ndipo mphamvu ya mafuta ndi yabwino kuposa mafuta. Graphite ufa sizovuta kugwiritsa ntchito mwachindunji. Ikhoza kusakanikirana ndi phala ndi mafuta pang'ono kapena madzi.

Vavu ya pulagi idzadzazidwa ndi mafuta pa nthawi yoikidwiratu, apo ayi n'zosavuta kuvala ndi kutuluka.

③ Sungani zidutswa zonse ziwiri. Maboti a flange ndi othandizira azikhala osasunthika ndipo sadzakhala omasuka. Ngati mtedza womangirira pa gudumu la m'manja ndi womasuka, uyenera kumangidwa munthawi yake kuti usavale cholumikizira kapena kutaya gudumu lamanja.

Gudumu lamanja silidzatayika ndikusinthidwa munthawi yake. Kuthamanga kwapang'onopang'ono kwapang'onopang'ono sikuyenera kutsatiridwa kapena kusakhala ndi chilolezo chololeza. M'malo owonongeka mosavuta ndi mvula, matalala, fumbi, ndi zina zotero, ndodo ya valve idzakhala ndi chivundikiro chotetezera. Wolamulira pa valve adzakhala wathunthu komanso wolondola. Chisindikizo chotsogolera, chivundikiro ndi zipangizo za pneumatic za valve ziyenera kukhala bwino. Chovala chotchinga chizikhala chopanda kukhumudwa komanso kusweka.

Kuonjezera apo, sikuloledwa kugogoda valavu, kuthandizira zinthu zolemetsa kapena kuimirira ogwira ntchito kuti asawononge valavu ndi kuwononga valavu. Makamaka, mauna opanda zitsulo ndi ma valve otayira zitsulo ndizoletsedwa.

Sungani tsiku ndi tsiku zipangizo zamagetsi. Kukonza zida zamagetsi nthawi zambiri sikuchepera kamodzi pamwezi. Zomwe zili mkati mwa kukonza zikuphatikizapo: maonekedwe adzakhala oyera popanda kusonkhanitsa fumbi, ndipo zipangizo sizidzaipitsidwa ndi nthunzi, madzi ndi mafuta; Malo osindikizira ndi mfundo ziyenera kukhala zolimba komanso zothina. Palibe kutayikira;

Gawo lopaka mafuta lidzadzazidwa ndi mafuta molingana ndi malamulo, ndipo mtedza wa valve udzadzazidwa ndi mafuta; Gawo lamagetsi liyenera kukhala losasunthika popanda kulephera kwa gawo, chosinthira chodziwikiratu ndi relay yotenthetsera sichimangiriridwa, ndipo chowunikira chiziwonetsedwa bwino.

2,Ndi malamulo ati oyendetsera ntchito ndi kukonza mavavu ayenera kutsatira

Kukonza ndi kasamalidwe ka ma valve kumayenera kutsatira izi:

1. Vavu yothandizira ya solenoid ya valve ya nkhalango yamvula idzawunikiridwa mwezi uliwonse ndipo iyenera kuyesedwa poyambira. Ngati ntchitoyo ndi yachilendo, iyenera kusinthidwa pakapita nthawi;

2. Mphamvu zamagetsi ndi kutsegula ndi kutseka kwa valve yamagetsi ndi solenoid valve zidzayesedwa mwezi uliwonse;

3. Ma valve onse olamulira pa dongosololi adzakhazikitsidwa pamalo otseguka kapena otchulidwa ndi zisindikizo zotsogolera kapena unyolo. Zisindikizo zotsogola ndi maunyolo aziyang'aniridwa kamodzi pamwezi. Zikawonongeka kapena zowonongeka, zidzakonzedwa ndikusinthidwa pakapita nthawi;

4. Valavu yowongolera mu chitsime cha valavu yakunja ndi paipi yolowera madzi iyenera kuyang'aniridwa kamodzi kotala, ndipo idzatsimikiziridwa kuti yatsegulidwa kwathunthu;

5. Maonekedwe a vavu yowongolera magwero a madzi ndi gulu la valavu ya alamu aziwunikiridwa tsiku lililonse, ndipo dongosololi lizikhala lopanda vuto;

6. Kuyesedwa kwa madzi kuchitidwa pazitsulo zonse zoyesa madzi omaliza ndi ma valve oyesa madzi otsekemera a valavu ya alamu ya dongosolo lililonse kotala, ndipo ngati kuyambika kwa dongosolo, ntchito ya alamu ndi kutulutsa madzi ndizoyenera kufufuzidwa;

7. Pamene valavu yoperekera madzi a tauni yatsegulidwa kwathunthu, kupanikizika kwapadera kwa wolepheretsa kubwerera kumbuyo kudzayesedwa mwezi uliwonse, ndipo idzatsatira zofunikira zomwe zikugwirizana ndi zomwe zikuchitika masiku ano: kuchepetsa kuthamanga kwa backflow blocker GB / T 25178, low resistance backflow woletsa JB / T 11151 ndi chotchinga kawiri valavu backflow blocker CJ / T 160.
