Nkhani

Pankhani ya zomangamanga zam'madzi, kusankha ma valve ndikofunikira, pakati pawo 316 zitsulo zosapanga dzimbiri zitsulo ndi 304 zitsulo zosapanga dzimbiri zitsulo ndizosankha zofala. Komabe, dzimbiri za mavavu a mpira wosapanga dzimbiri ndi kuchuluka kwa ayoni a kloridi m'malo am'madzi ndi vuto lalikulu, lomwe lingakhudze magwiridwe antchito ndi moyo wautumiki wa mavavu, komanso kuwopseza ntchito yotetezeka komanso yokhazikika ya dongosolo lonse laumisiri wapamadzi. Tiyeni tikambirane mwatsatanetsatane mmene zinthu ziwiri zosapanga dzimbiri mpira mavavu m'nyanja ndi njira yothetsera dzimbiri chloride ion.

Monga malo opangira mafakitale kumpoto kwa China, Tianjin ili ndi makampani ambiri opangira ma valve, omwe amapangitsa kuti pakhale mgwirizano waukulu wamakampani. Izi zimapangitsa makampani opanga ma valve agulugufe aku China kukhala ndi mwayi wodziwikiratu pakugula zinthu, zosintha za zida, komanso kusinthana kwaukadaulo.

M'makampani opanga mankhwala, chitetezo ndi mphamvu zamapaipi zimagwirizana mwachindunji ndi kukhazikika ndi chitetezo cha njira yonse yopangira. Monga zida zowongolera zamadzimadzi, China Chemical Butterfly Valve yakhala yofunika kwambiri komanso yofunika kwambiri popanga mankhwala ndi kukana kwa dzimbiri kwamankhwala.

Masiku ano, kutetezedwa ndi kuyeretsedwa kwa madzi kwakhala chinthu chofunika kwambiri padziko lonse lapansi. China, monga mzinda wofunikira wamafakitale komanso malo okhala ndi anthu ambiri m'dziko langa, kufunikira kochotsa zimbudzi kumawonekera. M'dongosolo lachimbudzi, Valve ya Gulugufe ya China Sewage Treatment Butterfly imagwira ntchito yofunika kwambiri ndipo imakhala chida chofunikira pakuyeretsa madzi.

M'madera ambiri opanga mafakitale, kulamulira madzimadzi m'madera otentha kwambiri nthawi zonse kwakhala vuto lovuta kwambiri. Ndi ntchito yake yabwino kwambiri komanso khalidwe lodalirika, valavu ya butterfly yotentha kwambiri ya China yakhala yabwino kwambiri poyankha zovuta za kutentha kwapamwamba ndi kukwaniritsa kulamulira bwino, kutsegula ulendo watsopano wa ntchito yokhazikika yopangira mafakitale.

Ndi kupita patsogolo mosalekeza kwa mfundo zoteteza zachilengedwe ku China, ukadaulo wa flue gas desulfurization (FGD) wakhala ulalo wofunikira pakuwongolera kuwononga mafakitale. Mu likulu la mafakitale la China, mavavu agulugufe a desulfurization, monga zigawo zazikulu za dongosolo la desulfurization, akhala zida zazikulu zowonetsetsa kuti ntchito yokhazikika ya mapulojekiti oteteza chilengedwe ndi yodalirika komanso yolimba. Nkhaniyi kusanthula mmene China desulfurization agulugufe mavavu angathandizire kuteteza chilengedwe desulfurization ntchito kukwaniritsa kuyeretsedwa koyenera kuchokera mbali zitatu: ubwino luso, zochitika ntchito ndi phindu makampani.

M'nyanja yamkuntho, ntchito yokhazikika ya zombo ndi yosasiyanitsidwa ndi machitidwe abwino komanso odalirika oyendetsera madzimadzi. China Marine Butterfly Valve, monga mlonda wachitetezo chamadzimadzi pakuyenda panyanja, imaperekeza kuyenda kotetezeka kwa zombo ndi machitidwe ake abwino komanso odalirika.
