Nlekọta nke mmepụta nchekwa na nke mepere anya na-agụnye nsị mmanụ, ntanye mmiri, uzuoku uzuoku, ntanye anwụrụ ọkụ, ntanye ash, ntanye coal, ntapu uzuzu na ntanye gas, nke bụ ihe anyị na-akpọ "na-agba ọsọ, na-agbapụta, ntanye na ntanye". Taa, anyị na-achikota ụfọdụ mgbochi mgbochi nke "na-agba ọsọ, na-ebupụta, ntapu na ntapu" maka ntụnye aka.
M usoro mgbochi maka mmiri na uzuoku ntapu nke valves.
1. All valves ga-adị n'okpuru ọkwa dị iche iche nke ule hydrostatic mgbe ịbanye na osisi.
2. Valves nke kwesịrị ịkwasa maka mmezi ga-abụ ala.
3. N'ime usoro nhazi, ọ dị mkpa iji nlezianya lelee ma a na-agbakwunye nkwakọ ngwaahịa na ma ọ bụrụ na a na-eme ka gland ahụ sie ike.
4. Tupu ntinye nke valvụ, lelee ma enwere uzuzu, ájá, iron oxide na sundries ndị ọzọ n'ime valvụ ahụ. Ọ bụrụ na e nwere nke ọ bụla n'ime ihe ndị a dị n'elu, a ga-ehichapụrịrị tupu echichi.
5. All valves ga-onwem na gasket nke kwekọrọ na ọkwa tupu echichi.
6. Mgbe ị na-etinye ọnụ ụzọ flange ahụ, a ghaghị imechi ihe nkedo ahụ. Mgbe ị na-eme ka bolts flange dị ike, a ga-emesi ha ike n'akụkụ ntụzịaka n'aka nke ya.
7. N'ime usoro ntinye valvụ, a ghaghị itinye valvụ niile n'ụzọ ziri ezi dị ka usoro na nrụgide siri dị, machibido iwu na-enweghị usoro na ngwakọta. A ga-agụrịrị valvụ niile ma dekọọ dịka usoro ahụ si dị tupu echichi.
II Akpachara anya maka mwepu nke coal awụfuru.
1. A ghaghị itinye flanges niile na ihe mkpuchi.
2. Ebe ndị na-agbapụta ntụ ntụ bụ valvụ coal na ntinye na ntinye nke pulverizer, onye na-eri nri, flange nke onye na-emepụta ihe, na akụkụ niile nwere njikọ flange. N'ihi nke a, a ga-enyocha akụkụ niile nke akụrụngwa nke ndị na-emepụta ihe niile na-adị njikere ịwụ ntụ ntụ, na ndị na-enweghị ihe mkpuchi ga-agbakwunye ugboro abụọ, a ga-agbatịkwa ihe nkedo.
3. A ga-eme usoro ndị a maka nkwụsị nke coal na-ekpo ọkụ na nkwụsị nke welded nke ọkpọkọ ọkpọkọ.
3.1 tupu ịgbado ọkụ, a ga-eji nlezianya na-ehichasị ebe a na-agbado ọkụ ka ọ bụrụ nke dara dara na oghere a chọrọ maka ịgbado ọkụ.
3.2 tupu nkwonkwo ụkwụ, a ga-edobe mkpochapụ nkwonkwo ụkwụ ma amachibidoro nkwonkwo mmanye nke ọma.
A ghaghị iji ihe ịgbado ọkụ 3.3 mee ihe n'ụzọ ziri ezi, na preheating ga-emerịrị dị ka achọrọ na ihu igwe oyi.
III Usoro mgbochi maka mwepu sistemu mmanụ na mpụta mmanụ.
1. N'oge ntinye nke pipeline mmanụ, nkwonkwo flange niile ma ọ bụ njikọ njikọ nke nwere eriri screw ga-enwerịrị ihe mkpuchi mmanụ na-eguzogide mmanụ ma ọ bụ pad asbestos na-eguzogide mmanụ.
2. Leakage ihe nke mmanụ usoro na-tumadi lekwasị flange na n'otu na eri, otú bolts ga-tightened evenly mgbe wụnye flange. Gbochie ntapu ma ọ bụ ntọhapụ.
3. N'ime usoro nzacha mmanụ, ndị ọrụ na-arụ ọrụ ga-anọgide na-arụ ọrụ mgbe niile, ma ọ bụ iwu siri ike ịhapụ ọkwa ahụ ma gafere ọkwa ahụ.
4. Kwụsị mmanụ mmanụ tupu ị gbanwee akwụkwọ nzacha mmanụ.
5. Mgbe ị na-etinye ihe nzacha mmanụ nwa oge na-ejikọta ọkpọkọ (plastic transperent hose nke dị elu), a ghaghị ijikọta njikọ ahụ nke ọma na waya ndu iji gbochie mmanụ ahụ ịwụpụ mgbe mmanụ mmanụ na-agba ọsọ ogologo oge.
IV. gbochie akụrụngwa na ọkpọkọ ka ọ ghara ịfụ ụfụfụ, na-ebupụta, ntapu na ịwụpụ, yana usoro mgbochi ndị a:
N'ihi na flange sealing gasket n'elu 1.2.5mpa, metal winding gasket ga-eji.
2.1.0mpa-2.5mpa flange gasket ga-abụ asbestos gasket na-ese na ojii ndu ntụ ntụ.
3.1.0mpa mmiri pipeline flange gasket ga-abụ roba gasket na-ese na nwa ndu ntụ ntụ.
4. Ngwunye nke mgbapụta mmiri ga-abụ ngwugwu ihe mejupụtara Teflon.
5. A ga-atụgharị eriri asbestos nke a na-eji na-emechi akụkụ nke anwụrụ ọkụ na ikuku coal pipes ma tinye ya na nkwonkwo nke ọma n'otu oge. A machibidoro iwu ịgbakwụnye ya n'ike ka emechara skru.
V. A ga-eme ihe ndị na-esonụ iji kpochapụ nkwụsị nke valvụ ahụ: (a ga-eme ihe ndị a iji gbochie nkwụsị nke valve)
1. Wụnye ọkpọkọ, hichaa ọnụ ọgụgụ ígwè oxide na mgbidi dị n'ime nke pipeline na-enweghị ihe ọ bụla, ma hụ na mgbidi dị n'ime nke pipeline dị ọcha.
2. Gbaa mbọ hụ na valves na-abanye na saịtị ahụ ga-abụrịrị n'okpuru 100% hydrostatic test.
3. A ga-ekpochapụ valvụ niile (ma e wezụga valvụ ntinye) maka nyocha, ichikota na nrụzi, na ndekọ na akara ga-eme ka ịchọta ya. A ga-edepụta valvụ dị mkpa n'ụzọ zuru ezu maka nnabata nke abụọ, iji mezuo ihe achọrọ nke "stamping, nyocha na ndekọ".
❖ ọ bụrụ na a na-atụfu ya, n'ihi gịnị?
(1) kọntaktị n'etiti oghere na mmechi akụkụ na abụọ akara n'elu oche valvụ;
(2) ọnọdụ dabara adaba nke mbukọ, stem na igbe nri;
(3) njikọ n'etiti valvụ ahụ na bonnet
A na-akpọ ntanye nke mbụ na-agbapụta n'ime, ya bụ, valvụ adịghị emechi emechi, nke ga-emetụta ikike nke valvụ ahụ iji bepụ ọkara. A na-akpọ ntanye abụọ ikpeazụ a na-akpọ ntanye, ya bụ, nke na-esi n'ime ya pụta n'èzí nke valvụ ahụ. Ntupu ga-akpata mfu ihe onwunwe, mmetọ gburugburu ebe obibi na ọbụna ihe mberede.
