Ndemanga za "Kutha Kwathunthu" kwa Kalasi Yoyamba Yozimitsa Moto mu 2018: Kuyika Mavavu

1) Zofunikira pakuyika:

① Ma valve omwe amagwiritsidwa ntchito mu payipi yosakanikirana ndi thovu amaphatikizapo ma valve a manual, magetsi, pneumatic ndi hydraulic.Atatu omalizawa amagwiritsidwa ntchito kwambiri m'mapaipi a mainchesi akulu, kapena kuwongolera kwakutali komanso kodziwikiratu.Ali ndi miyezo yawoyawo.Ma valve omwe amagwiritsidwa ntchito mu payipi yosakanikirana ndi thovu ayenera kukhala Pakuyika molingana ndi miyezo yoyenera, valavu iyenera kukhala ndi zizindikiro zowonekera ndikutseka.

②Mavavu okhala ndi zowongolera zakutali ndi ntchito zowongolera zokha ziyenera kukhazikitsidwa malinga ndi kapangidwe kake;akayikidwa pamalo ophulika ndi ngozi yamoto, akuyenera kukhala motsatira mulingo wapano wa dziko "Electrical Installation Engineering Explosion and Fire Hazardous Environment Electrical Installation Construction and Acceptance Specification 》(GB50257-1996).

③Chitsulo chokwera tsinde lachipata ndi valavu yowunikira yomwe imayikidwa pamalo pomwe payipi ya thovu ya jet yomira ndi njira yozimitsira moto yolowera m'madzi imalowa mu thanki yosungira iyenera kuyikidwa mopingasa, ndipo mayendedwe omwe alembedwa pa valavu ayenera kukhala. mogwirizana ndi kayendedwe ka thovu.Kupanda kutero, thovulo silingalowe mu thanki yosungiramo, koma sing'anga yomwe ili mu tanki yosungiramo imatha kubwereranso mupaipi, zomwe zimapangitsa ngozi zambiri.

④Chiyerekezo cha kuthamanga, fyuluta ya chitoliro, ndi valavu yoyang'anira yomwe imayikidwa pa payipi yamadzimadzi yosakanikirana ndi thovu polowera kwa jenereta ya thovu yowonjezera yowonjezera iyenera kuikidwa pa chitoliro cha nthambi yopingasa.

⑤ Valavu yotulutsa yokhayokha yomwe imayikidwa papaipi yamadzimadzi yosakanikirana ndi thovu iyenera kuyikidwa molunjika makinawo atatha kuyesa kukanikiza ndikuthamangitsa.Valavu yotulutsa yokha yomwe imayikidwa pa payipi yamadzimadzi yosakanikirana ndi thovu ndi chinthu chapadera chomwe chimatha kutulutsa mpweya mupaipi.Paipiyo ikadzadzazidwa ndi thovu losakanizika (kapena litadzazidwa ndi madzi panthawi yokonzanso), mpweya womwe uli mupaipi umayendetsedwa mwachilengedwe kupita pamalo okwera kwambiri kapena malo omaliza osonkhanitsira gasi mupaipiyo.Valavu yotulutsa yokha imatha kutulutsa mipweya iyi.Pamene payipi Vavu idzatseka yokha ikadzazidwa ndi madzi.Kuyika koyima kwa valve yotulutsa mpweya ndikofunikira pakupanga kwazinthu.Kuyikako kumachitika pambuyo poti dongosolo ladutsa mayeso okakamiza ndikuthamangitsa kuti mupewe kutsekeka komanso kukhudza kutulutsa.

⑥Vavu yoyang'anira papaipi yamadzimadzi yosakanikirana ndi thovu yolumikizidwa ndi chipangizo chopangira thovu iyenera kuyikidwa kunja kwa mawonekedwe oyezera mphamvu kunja kwa ngalande yamoto, ndi zizindikiro zowonekera ndikutseka;pamene thovu wosanganiza payipi madzi waikidwa pansi, unsembe kutalika kwa valavu ulamuliro nthawi zambiri ankalamulidwa pa Pakati pa 1.1 ndi 1.5m, pamene valavu kuponyedwa chitsulo kulamulira ntchito m'madera amene kutentha yozungulira ndi 0 ℃ ndi pansi, ngati payipi imayikidwa pansi, valavu yoyendetsera chitsulo iyenera kuikidwa pa chokwera;ngati payipi itakwiriridwa pansi kapena kuikidwa mu ngalande, chitsulo choponyera valve valve yoyendetsera iyenera kuikidwa mu chitsime cha valve kapena ngalande, ndipo njira zoletsa kuzizira ziyenera kuchitidwa.

⑦ Pamene chozimitsira thovu chozimitsira moto m'malo osungiramo tanki chimakhalanso ndi ntchito ya semi-fixed system, ndikofunikira kuyika chitoliro cholumikizira ndi valavu yowongolera ndi chivundikiro chokwiyitsa papaipi yamadzi osakanikirana a thovu kunja kwa ngalande yamoto. thandizirani magalimoto ozimitsa moto kapena zozimitsa moto zina zam'manja Zida zimalumikizidwa ndi zida zozimitsa moto za thovu pamalo osungiramo tanki.

⑧ Kutalika kwa valavu yowongolera yomwe imayikidwa pa thovu losakanikirana lamadzimadzi nthawi zambiri limakhala pakati pa 1.1 ndi 1.5m, ndipo chizindikiro chotsegulira ndi kutseka chiyenera kukhazikitsidwa;pamene kutalika kwa kuyika kwa valve yolamulira kuli kwakukulu kuposa 1.8m, nsanja yogwiritsira ntchito kapena ntchito iyenera kukhazikitsidwa.

⑨Chitoliro chobwerera chokhala ndi valavu yowongolera yoyikidwa pa chitoliro chotulutsa chapopi yamoto chiyenera kukwaniritsa zofunikira.Kutalika kwa valavu yowongolera nthawi zambiri kumakhala pakati pa 0.6 ndi 1.2m.

⑩ Valavu yolowera papaipi iyenera kuyikidwa pamalo otsika kwambiri kuti athandizire kutuluka kwamadzi mupaipi.

2) Njira yowunikira:zinthu ① ndi ② zimawonedwa ndikuwunikiridwa molingana ndi zofunikira za miyezo yoyenera, ndikuwona kwina ndi kuwunika kwa olamulira.
