Kuchengetedza vharafu yekuyamura, iyo inozivikanwawo sevhavhavha yekudzivirira, ndeye otomatiki yekuyamura mudziyo inofambiswa nepakati pressure. Inogona kushandiswa sevhavhavha yekudzivirira uye valve yekuyamura zvichienderana nekushandiswa.

Tichitora Japan semuenzaniso, kune tsanangudzo shoma dzakajeka dzemavharuvhu ekuchengetedza uye mavharuvhu ekuyamura. Kazhinji, midziyo yekuchengetedza inoshandiswa kune hombe yekuchengetedza simba midziyo yekumanikidza yakadai semaboilers inonzi mavharuvhu ekuchengetedza, uye ayo akaiswa pamapombi kana zvimwe zvivakwa anonzi mavharuvhu ekuyamura. Nekudaro, maererano nezvinopihwa ne "Technical Standards yeThermal Power Generation" yeBazi reInternational Trade uye Indasitiri yeJapan, zvakakosha zvikamu zvekuchengetedza simbi inotsanangura kushandiswa kwemavharuvhu ekuchengetedza, senge boilers, superheaters, reheaters, nezvimwe. Nenzira iyi, chivharo chekuchengetedza chinoda kuvimbika kudarika valve yekuyamura.

Pamusoro pezvo, kubva pamitemo yekudzora gasi yepamusoro-soro yeBazi reBasa reJapan, mitemo yeBazi rezvekutakurwa uye masangano ezvikepe pamatanho ese, kuzivikanwa uye mirairo yevhoriyamu yekubuda kwakachengeteka, tinodaidza vharafu inovimbisa vhoriyamu yekubuda vharuvhu yekudzivirira, uye vharafu isingavimbisi vhoriyamu yekuburitsa vharuvhu yekuyamura. MuChina, ingave yakazara-yakavhurika kana micro-yakavhurika, iyo pamwe chete inodaidzwa kunzi vharafu.

1. Muchidimbu

Mavharuvhu ekuchengetedza akakosha ekuchengetedza mabhailers, midziyo yekumanikidza uye zvimwe zvekumanikidza. Kuvimbika kwekushanda kwavo uye hutano hwekuita kwavo kwakabatana zvakananga nekuchengetedzwa kwemidziyo nevashandi, uye zvakabatana zvakanyanya nekuchengetedza simba uye kuchengetedza kwezvakatipoteredza. Nekudaro, vamwe vashandisi uye madhipatimendi ekugadzira anogara achisarudza iyo isiriyo modhi pakusarudza. Nechikonzero ichi, chinyorwa ichi chinoongorora kusarudzwa kwemavharuvhu ekuchengetedza.

2. Tsanangudzo

Izvo zvinonzi mavharuvhu ekuchengetedza kazhinji anosanganisira mavharuvhu ekuyamura. Kubva pamitemo yekutarisira, mavharuvhu akaiswa zvakananga pamhepo boilers kana rudzi rwekumanikidza midziyo inofanirwa kubvumidzwa nedhipatimendi rekutarisa tekinoroji. Mupfungwa nhete, anonzi mavharuvhu ekuchengetedza, uye mamwe anowanzonzi mavharuvhu okuyamura. Mavharuvhu ekuchengetedza uye mavharuvhu ekuyamura akafanana zvakanyanya mukugadzirisa uye kuita. Ose ari maviri anoburitsa otomatiki svikiro remukati kana kuvhurika kudzvanywa kwadarika kuti ive nechokwadi chekuchengetedzwa kwemidziyo yekugadzira. Nekuda kwekufanana kwakakosha uku, vanhu vanowanzo vhiringa zviviri izvi kana vachizvishandisa. Pamusoro pezvo, mimwe michina yekugadzira inotarawo kuti chero mhando inogona kusarudzwa mumitemo. Nokudaro, misiyano pakati pezviviri izvi inowanzofuratirwa. Somugumisiro, matambudziko akawanda anomuka. Kana tichida kupa tsananguro yakajeka yezviviri izvi, tinogona kuzvinzwisisa zvinoenderana netsanangudzo iri muchikamu chekutanga cheASME Boiler uye Pressure Vessel Code:

(1)Kuchengetedza vharafu, mudziyo wokuyamura wotomatiki unofambiswa ne static pressure yepakati pamberi pevharuvhu. Iyo inoratidzirwa nechiito chakazara chekuvhura nekuvhura kamwe kamwe. Inoshandiswa mukugadzira gasi kana steam.

(2)Ivhavha yekuyamura, inozivikanwawo sevhavha yekufashukira, ndeye otomatiki yekuyamura dhizaini inofambiswa neiyo static pressure yepakati pamberi pevharuvhu. Inovhura maererano nekuwedzera kwekumanikidzwa kudarika simba rekuvhura. Inonyanya kushandiswa mukushandiswa kwemvura.
