VIGA Faucet Mugadziri 
Munguva pfupi yapfuura, Nanjing Municipal Quality Supervision Bureau yakaburitsa mhedzisiro ye 2017 kuongororwa zvisina tsarukano kwemhando yemidziyo yemumba, zvinosanganisira faucets, simbi isina simbi inonyura, mabhuraketi ekugezera uye mahwendefa asina pendi. Kupfuura mwero wepombi ndiyo yakaderera pa 67.5%, izvo mwero wekupfuura wemapombi ane mutengo paRMB 100 uye pazasi chete 14.3%.
The unqualified rate yematepi pasi 100 yuan yakakwirira se 85.7%
Izvi zvisati zvaitika, iyo Nanjing Municipal Hunhu uye Technical Supervision Bureau yakapa Nanjing Chigadzirwa Hunhu Kutarisisa uye Inspection Institute kuti iite ongororo isina kurongeka. 40 mabheti ezvigadzirwa zvespout zvinotengeswa mumabhizinesi ekugadzira eNanjing, nzvimbo dzekutenderera uye e-commerce mapuratifomu. Mushure mekuongororwa, 27 mabatches akapfuura uye 13 zvikwata zvakundikana, pamwe nekupasa kwe 67.5%.
Nanjing Quality Supervision Bureau yakarongedza mhinduro dzebvunzo zvichienderana nekwakabva chigadzirwa uye mutengo wemhando, uye mhedzisiro yacho inobata maziso.
The the 40 mabheji ezvigadzirwa zvepombi mune iyi yekungoongorora yakatorwa kubva kuzvitoro zvenyama, e-commerce mapuratifomu uye makambani ekugadzira, zvichiteerana 20 batches, 19 batches uye 1 batch. Pakati pavo, mwero wekukodzera kwechigadzirwa chechitoro chenyama ndiwo wakaderera, 55%; iyo e-commerce papuratifomu chigadzirwa qualification rate iri 78.9%; iyo yekugadzira bhizinesi chigadzirwa qualification rate ndeye 100%.
Kubva pakuona kwemitengo yezvigadzirwa, chiyero chekupasa kwezvigadzirwa zve 400 yuan uye pamusoro ndizvo 100% (kukundikana mwero 0%), chiyero chekupasa kwezvigadzirwa pakati 200 yuan uye 400 yuan iri 85.7% (kukundikana mwero 14.3%), 100 yuan kuChiyero chekupasa kwezvigadzirwa pakati 200 yuan iri 62.5% (unqualified rate is 37.5%), uye mwero wekupasa kwezvigadzirwa zve 100 yuan uye pazasi ndizvo 14.3% (unqualified rate is 85.7%).
2 zvimedu zvezvinosvibisa zvesimbi mumuromo wemvura zvakapfuura mwero
Iyi sampling yekuongorora yakaitwa zvinoenderana neGB 18145-2014 “Ceramic Sheet Yakavharwa Mvura Nozzle” uye GB 25501-2010 “Mvura Yemvura Kushandisa Nesimba Muganho Ukoshi uye Mvura Yekushandisa Nekugona Giredhi”. Pakati pe 13 zvikwata zvezvigadzirwa zvisina kukodzera, zvinhu zvisingakodzeri zvinonyanya zvinosanganisira kuomarara kwepamusoro, giredhi rekushanda kwemvura, kuyerera kufanana uye zvinhu. Pakati pavo, kuonekwa kwesimbi inosvibisa (tungamira) mumabheji maviri ezvigadzirwa zvakapfuura mwero.
Pamusoro pe, kuongororwa kwesampling kwairevawo kuQB / T 1334-2013 “General Specifications for Water Spouts” standard, uye kuiswa chisimbiso kwezviputi kwaiomeswa nechando -10 ℃ zve 4 maawa, 8 maawa, 12 maawa, uye 24 maawa Risk monitoring. Mushure mekuongororwa, 33 mabhechi emvura nozzles anozadzisa zvinodiwa, uye mwero wekuteerera uri 82.5%.
Kuongorora chinhu chekuongorora
① Kuyerera kwakafanana uye giredhi rekushanda kwemvura
Kuyerera kwakafanana uye giredhi rekushanda kwemvura Mumuenzaniso weiyi ongororo isina kurongeka, batch rimwe regiredhi rekushanda kwemvura rakakundikana, chiyero chekupasa chirongwa chaive 97.5%; mabheji matatu ekuyerera kufanana akakundikana, chiyero chekupasa chirongwa chaive 92.5%. Zvinhu zviviri izvi zvinodiwa pakushanda nesimba kwegomba remvura, uye kuenzana kweyero yekuyerera ndicho chinodiwa chekuongorora chiyero chemvura yehuputi. Kuwedzera kuyerera kwemazinozzles emvura kunokonzeresa kutambisa zviwanikwa zvemvura, izvo zvisingaenderane nekushandiswa kweChina chekuchengetedza simba uye kudzikisa emission policy.
②Surface corrosion resistance
Pakati pemienzaniso yeiyi ongororo isina kujairika, 12 mabhechi ekudzivirira ngura kwepamusoro atadza, uye kupasa kwechirongwa ichi kwaive 70%. Zvigadzirwa zvisina kugutsa corrosion resistance pamusoro pepamusoro zvinowanzoita ngura panguva yekushandiswa uye hazvipe dziviriro., kukanganisa aesthetics uye kushandiswa kwechigadzirwa. Kuramba kwecorrosion kwepamusoro pemvura nozzle haingoenderana chete neiyo electroplating process yebhizinesi., asiwo inosanganisira zvakasiyana-siyana sezvinhu, casting process, kukwenenzvera uye pretreatment.
③ Kunaya kwesimbi inosvibisa
Mumuenzaniso wemuenzaniso uyu, 2 zvimedu zvezvinosvibisa zvesimbi zvakaiswa zvisina kukodzera. Chiyero chakakodzera chechirongwa ichi chaive 95%. Kunaya kwezvinosvibisa simbi kune chekuita nehutano hwevanhu, kunyanya kuunganidzwa kwemutobvu mumuviri wemunhu, izvo zvinogona kukonzera njodzi dzehutano kwenguva refu uye kukanganisa zvakajairwa physiological mabasa emuviri wemunhu. Chikamu chemhangura chechigadzirwa che spout chakaderera, uye maitiro ekugadzira bhizinesi haaenderane nechiyero, iyo ndiyo inokonzera kunaya kwakanyanya kwesimbi inosvibisa.
(Masamples asina kukodzera emvura inosvibisa yegoridhe)
④Zvinhu
Pakati pemienzaniso yeiyi ongororo isina kujairika, 7 zvikwata zvezvinhu zvakakundikana, uye kupasa kwepurojekiti kwaive 82.5%. Zvimwe zvigadzirwa zvinoshandisa zinc alloy, inova zvinhu zvinoora izvo chete 1/3 yemhangura alloy. Nyaya iyi iri nyore kuita ngura, izvo zvisingakanganisi chitarisiko chete, asiwo inoderedza simba remuromo, uye inodonha uye inotsemuka mushure menguva yekushandiswa. Kuenzaniswa nemhangura alloys, zinc alloys yakaderera mumutengo uye iri nyore kugadzira. Mamwe makambani anoshandisa zinc alloys kutsiva alloys emhangura kuitira kudzora mitengo uye kuderedza kugadzirisa zvinongedzo, kuitira kuwana purofiti yakakura.
⑤Zvinhu zvine njodzi (tembiricha test)
Iyi test test yakaita tembiricha yekuyedza, ndiko, iyo yekuisa chisimbiso yakaedzwa mushure mekuomesa muromo wemvura pa -10 ℃ zve 4 maawa, 8 maawa, 12 maawa, uye 24 maawa. Mushure mekuedza, pakati pe 40 mabheji ematepi mune ino yekuongorora isina kujairika, huwandu hwe 7 mabhechi airatidza kuvuza pasi penzvimbo yakaderera tembiricha.
Parizvino, hapana inoenderana chiyero chenyika cheyero yekupikisa kukosha kwepombi. Mumamiriro ezvinhu akajairika, muromo wemvura hauzove nechando uye wakatsemuka pamadhigirii mashoma pazasi zero, asi mushure mechando pane kutonhora kwakadzika, mvura iri muspool inokura yoita aizi, izvo zvichaita kuti kudzvinya simba pamusoro spool. Pachave nekudonha pakubatana. Kuti uchengetedze mari, mamwe mabhizinesi ekugadzira anoshandisa yakashata mhando yendarira sechinhu chekukanda chepombi. Iyo metal ductility yakanyanya kuderedzwa, uye zviri nyore kuomesa nechando uye kutyora pane yakaderera tembiricha.

Zano revatengi
① Dzivisa kutenga zinc alloy faucets
Zinc alloys zvinhu zvinoparadza zvakanyanya, uye zvigadzirwa zvakadaro zvinofanirwa kudziviswa kutanga pakutenga mapombi. Inogona kusiyaniswa maererano nemukati wemukati wechigadzirwa. Zvinhu zvemhangura zvinowanzoita zvekukanda. Iyo flatness yemukati rusvingo rwechigadzirwa haisi yakanaka kwazvo. Iyo zinc alloy inowanikwa nekukuya jekiseni. Rusvingo rwemukati ruchava rwakatsetseka uye rusvingo rwemukati ruchava nemitsara yekuparadzanisa iri pachena. Pasi pemamiriro ezvinhu, ruvara rwezinc alloy runogona kunge ruchena, nepo alloy yemhangura inogona kunge yero.
② Dzivisa kutenga mapombi anodhura
Iyo isingakodzeri mwero we faucets pasi 100 yuan yakakwirira se 85.7%, uye zvinosanganisira zvimwe zvinhu, tsvina yesimbi nezvimwe zvinhu zvine simba guru pahutano hwevatengi, saka hazvikurudzirwi kutenga.
③ Tarisa pamusoro
Ongorora nemaziso kuona kana nzvimbo ine electroplated ye spout ichipenya zvakafanana, uye chenjerera kuti pane zvakakanganisika zvakaita sekupepeta, kutsemuka, kupisa, pasi pachena, peeling, makwapa matema uye pachena gomba. Chimiro chepamusoro chenzvimbo yakapfapfaidzwa inofanira kuva yakanaka, yakatsetseka uye yunifomu isina kuremara senge sagging uye pachena pasi. Hapana burr uye grit kunzwa paruoko.
④ Tarisa shinda
Tambo yepombi yemuromo wemvura yakabatana nehosi yekubatanidza kana pombi. Kana uchitenga, tarisa nemaziso tarisa shinda pamusoro pemazino, mazino akatyoka nezvimwe zvirema, kunyanya teerera kune hurefu hunobudirira hwetambo yepombi.
⑤ Tarisa kunzwa
Unogona kuedza kusimudza mubato kumusoro, pasi, ruboshwe, uye kurudyi. Kana ichinzwa kureruka uye pasina blockage, zvinoreva kuti chivharo chevhavha chiri nani. Izvo zvikamu zvikuru zvehutano hwakanaka spout zvakagadzirwa nendarira. Ngwarira kusiyanisa zvigadzirwa zvinoshandisa alloy zvinhu uye engineering mapurasitiki, vane hutano uye hupenyu hwebasa huri hurombo.
⑥Kuchengetedza mvura
Iyo pombi ine bubbler iri nani kuchengetedza mvura. Kana uchitenga, unogona kunzwa kuyerera kwemvura nekuibata nemaoko ako. Mvura yakapfava inoyerera uye ichipupuma furo (mvura inoyerera bubble content) ratidza kuti bubbler ndeyemhando yakanaka.
