Ilwazi lokutlhogonyelwa kwevalvu

Ukuzeamavalvuekusebenzeni, kokeivalvuiingcenye kufanele zibe ziphelele begodu ziphelele. Amabhawudo we-flange ne-bracket aqakathekile, begodu imicu kufanele ihlale ikhona begodu akukavunyelwa ukukhululeka. Nangabe i-nati yokubophelela isondo lesandla itholakala ikhululekile, kufanele iqiniswe ngesikhathi ukugwema ukuguga kwejoyinti nofana ukulahlekelwa kwesondo lesandla neplayidi yegama. Nangabe isondo lesandla lilahlekile, akukavunyelwa bona libuyiselwe ngerentjhi elungisekako, begodu kufanele liqedwe ngesikhathi. Indlala yokupaka ayivunyelwe bona itjhinge namkha ingabi nesikhala sokuqinisa. Kweamavalvuendaweni engasilaphazeka lula lizulu, iqhwa, ithuli, ummoya nesihlabathi, isiqu sevalvu kufanele sifakwe isivikelo. Isikali esise-valve kufanele sigcinwe siqinile, sinembile begodu sikhanye. Iimvalo zomthofu, amakhephu kanye nezinto zomoya zevalvu kufanele zibe ziphelele begodu ziphelele. Ijakhethi yokuvikela akukafaneli ibe namagodi nofana imifantu.

Akukavunyelwa ukungqongqoza, ukujama nofana ukusekela izinto ezisindako ku-valve esebenzako; khulukhulu amavalvu angasiwo wesimbi kanyeamavalvu wensimbizivinjelwe khulu.

Ukugcinwa kwe-idleamavalvu

Ukugcinwa kwamavalvu angasebenziko kufanele kwenziwe ndawonye nemitjhini namapayipi, begodu umsebenzi olandelako kufanele wenziwe:

1. Hlanzaivalvu

Umgodi wangaphakathi wevalvu kufanele uhlanjululwe begodu uhlanzwe ngaphandle kweensalela kanye nesisombululo samanzi, begodu ingaphandle levalvu kufanele lisulwe ngaphandle kokusilaphazeka, amafutha,

2. Hlanganisaivalvuiingcenye

Ngemva kweivalvuayikho, ipumalanga angeze yahlukaniswa ukwenza entshonalanga, begodu iingcenye zevalvu kufanele zihlonywe ngokuzeleko ukwenza ubujamo obuhle bokusetjenziswa okulandelako nokuqinisekisa bonaivalvuisebujameni obuhle.

3. Ukwelatjhwa okulwisana nokugqwala

Khipha ukupakisha ebhokisini lokugcwalisa ukukhandela ukugqwala kwe-galvanicivalvuisiqu. Faka i-antirust kanye namafutha endaweni yokuvala ivalvu,ivalvuisiqu, i-valve stem nut, indawo eyenziwe ngomtjhini nezinye iingcenye ngokuya ngobujamo obuthileko; iingcenye ezipendiweko kufanele zipendwe ngepende elwisana nokugqwala.

4. Ukuvikeleka

Ukukhandela ukutjhayisana kwezinye izinto, ukuphathwa nokuhlukaniswa okwenziwe babantu, nangabe kuyatlhogeka, iingcenye ezithuthekako zevalvu kufanele zilungiswe, begodu ivalvu kufanele ipakishwe begodu ivikelwe.

5.ukulungiswa okujayelekileko

  Amavalvuegade ingasebenzi isikhathi eside kufanele ihlolwe begodu itlhogonyelwe qobe ukukhandela ukugqwala nokulimalaivalvu. Kweamavalvuebegade ingasebenzi isikhathi eside, kufanele isetjenziswe ngemva kokuphasa ukuhlolwa komfutho kanye nemitjhini, amadivayisi, namapayipi.

Ukutlhogonyelwa kwemitjhini kagesi

Umsebenzi wokutlhogonyelwa kwamalanga woke wedivayisi kagesi uvamise ukungabi ngaphasi kanye ngenyanga. Okuqukethwe kokutlhogonyelwa:

1. Ukubukeka kuhlanzekile ngaphandle kokuqongelela uthuli; idivayisi ayikho ukusilaphazeka ngomtjhiso, amanzi namafutha.

2. Idivayisi kagesi ivaliwe kuhle, begodu indawo ngayinye yokuvala nendawo kufanele iphelele, iqinile, iqinile, begodu ingavuzi.

3. Idivayisi kagesi kufanele igcotjhwe kuhle, ifakwe amafutha ngesikhathi begodu njengombana kutlhogeka, begodu inathi yesiqu sevalvu kufanele igcotjhwe.

4. Ingcenye kagesi kufanele ibe sebujameni obuhle, begodu igweme ukuguguleka komswakama nethuli; nangabe imanzi, sebenzisa i-500V megohmmeter ukulinganisa ukujamelana kokuvikela hlangana nazo zoke iingcenye ezithwala umtjhini kanye negobolondo, begodu inani akukafaneli libe ngaphasi kwe-o. Ukomisa.

5. Iswitjhi ezenzakalelayo ne-thermal relay akukafaneli ikhuphuke, isibani esibonisako sitjengisa kuhle, begodu akukho ukubhalelwa kokulahlekelwa kwesigaba, isekhethi emfitjhani nofana isekhethi evulekileko.

6. Ubujamo bokusebenza kwedivayisi kagesi bujayelekile, begodu ukuvulwa nokuvala kuyatjhuguluka.

Ukutlhogonyelwa kweensetjenziswa zomoya

Umsebenzi wokulondoloza welanga nelanga wedivayisi yomoya uvamise ukungabi ngaphasi kanye ngenyanga. Okuqukethwe okuqakathekileko kokutlhogonyelwa:

1. Ukubukeka kuhlanzekile ngaphandle kokuqongelela uthuli; idivayisi akukafaneli ingcoliswe mhwamuko wamanzi, amanzi namafutha.

2. Ukuvalwa kwesisetjenziswa se-pneumatic kufanele kube kuhle, begodu iindawo zokuvala namaphuzu kufanele ziphelele begodu ziqine, ziqinile begodu zingalimali.

3. Indlela yokusebenza ngezandla kufanele igcotjhwe kuhle begodu ivuleke begodu ivalwe kuhle.

4. Amajoyinti wegesi wokungena nokuphuma wesilinda akukavunyelwa bona alimele; zoke iingcenye zesilinda nehlelo lokuphayipha komoya kufanele zihlolwe ngokutjheja, begodu akukafaneli kube nokuvuza okuthinta ukusebenza.

5. Iphayiphu ayikavunyelwa bona itjhinge, isimemezeli kufanele sibe sebujameni obuhle, isibani esitjengisako sesimemezeli kufanele sibe sebujameni obuhle, begodu intambo yokuhlanganisa isimemezeli se-pneumatic nofana isimemezeli segezi kufanele sibe sihle ngaphandle kokuvuza.

6. Iivalvus esisetjenzisweni se-pneumatic kufanele sibe sebujameni obuhle, singavuzi, sivuleke ngokuguquguqukako, begodu sibe nokugeleza komoya okubushelelezi.

7. Idivayisi yoke yomoya kufanele ibe sebujameni obujayelekileko bokusebenza, ivuleke begodu ivalwe kuhle.
