The general situation of elevator industry
Makampani a elevator ku China adakula kwazaka zopitilira 60.Bizinesi yonyamula ma elevator yakhala dziko lalikulu kwambiri lopanga ma elevator komanso dziko lalikulu logwiritsa ntchito chikepe padziko lonse lapansi.Mphamvu yopanga pachaka ya elevator yafika mamiliyoni a mayunitsi.
Kukula kwa makampani okwera ndege kumakhala ndi ubale wosagwirizana ndi chitukuko cha zachuma cha dziko komanso chitukuko cha msika wogulitsa nyumba.Pambuyo pa kukonzanso ndi kutsegulidwa, zokolola za elevator ku China zakhala zikuwonjezeka ka zana ndipo kupezeka kwafika nthawi makumi asanu.Zikuoneka kuti padzakhala pafupifupi 540 zikwi zikepe kupanga ndi malonda mu 2014, amene kwenikweni chimodzimodzi monga 2013, ndipo adzapitiriza kutsogolera mayiko otukuka kwambiri ku Ulaya ndi United States.
Pakadali pano, ngakhale zilolezo zambiri zamabizinesi zakhala zikuyenda pa liwiro la 7M/S kapena kupitilira apo, ma elevator opangidwa ndi China amakhala makamaka ma elevator okhala ndi mita 5 pa sekondi imodzi, mawonekedwe osiyanasiyana onyamulira, ma elevator owonera malo ochepera 2.5 metres pamphindikati, zokwezera zachipatala zakunyumba. , ma escalator, misewu yodziwikiratu, ndi zikepe zapanyumba za nyumba ya villa, elevator yapadera ndi zina zotero.
Choyamba, zinthu zonse ndi panopa zinthu za chitukuko cha chikepe kunyumba ndi kunja
Kuyambira kubadwa kwa chikepe choyamba padziko lapansi chakhala zaka zoposa zana zapitazo, chikepe cha ku China chakhala ndi zaka zoposa 60 za mbiri yopangidwa.
Pakadali pano, ma elevator padziko lonse lapansi ndi 90% misika yapadziko lonse lapansi, Europe, America ndi China.Mitundu yotchuka kunja kwenikweni ndi American Otis, Swiss Schindler, German Thyssen Krupp, Finland Tongli, Japanese MITSUBISHI ndi Japanese Hitachi, ndi zina zotero.Mabizinesiwa ali ndi gawo lalikulu kwambiri padziko lonse lapansi, makamaka msika wapamwamba kwambiri.Ndipo nthawi zonse yakhala ikutenga msika wama elevator othamanga kwambiri.
Elevator yaku China yakhala chikepe chachikulu kwambiri padziko lonse lapansi m'zaka za zana la makumi awiri ndi chimodzi, koma ma elevator aku China akhala akupereka msika wapakhomo.Pakalipano, muzitsulo zokwana 500,000, mitundu isanu ndi umodzi yakunja ku China yagulitsa kupitirira theka la msika wapakhomo, ndipo zina mazana asanu kapena mazana asanu ndi limodzi zida zapakhomo zopangidwa ku China.Mabizinesi a makwerero amatenga theka lotsala la msika, ndipo gawo lake ndi lofanana ndi kuchuluka kwa kupanga ndi kugulitsa kwa mgwirizano pakati pa mabizinesi apanyumba zana limodzi ndi mitundu yakunja.
Ku China, pambuyo pa mndandanda wa elevator ya Kang Li ku Shenzhen Stock Exchange, makampani anayi omwe adalembedwa adalembedwa.Ndi ma elevator a Suzhou Kang Li, elevator ya Suzhou Jiangnan Jiajie, elevator ya Shenyang bolt, katundu watsiku la Guangzhou Guangzhou, ndipo makampani omwe adatchulidwa ndi mtsinje wa Yangtze amakongoletsa, nthawi yatsopano ndi makina a Hui Chuan.Magetsi.
China anayi kutchulidwa makampani mu msika zoweta chikepe, mu msika zoweta chikepe, pafupifupi 1/4, za 150 zikwi za kupanga pachaka ndi malonda;ena omwe ali pafupi ndi mabizinesi okwera 600 ku China (kuphatikiza mayina abizinesi ofanana ndi mabizinesi opanga ma elevator akunja) amagawana msika wotsalira wamagetsi wamagetsi wa 10-15 miliyoni, avareji yogulitsa 200 pachaka, yayikulu kwambiri Kugulitsa kwakukulu ndi pafupifupi mayunitsi 15000, ndipo Kugulitsa kochepa kwambiri kuli pafupifupi mayunitsi 20 ogulitsidwa mu 2014.
Kusanthula deta, USA Otis, Swiss Schindler, German Thyssen Krupp, Finland Tongli, Japan MITSUBISHI ndi Japan Hitachi mitundu isanu ndi umodzi ku China kugulitsa mayunitsi 250 miliyoni -30 miliyoni, Suzhou Kang Li elevator, Suzhou Jiangnan Jiajie elevator, Shenyang brintt elevator, Guangzhou Guang magawo atsiku okwana mayunitsi 150 zikwi;mabizinesi ena malonda 10-1 50 zikwi.
M'gulu la zikepe zonse ku China, malonda okwera okwera amakhala ndi gawo lalikulu kwambiri, pafupifupi 70% yazogulitsa zonse, pafupifupi mayunitsi 380,000, kutsatiridwa ndi chikepe chonyamula ndi escalator pafupifupi 20%, ndipo ena onse 10% amawona malo. ma elevator, ma elevator a odwala odwala komanso ma elevator akunyumba.
Awiri.Makhalidwe a luso la elevator kunyumba ndi kunja
Pakadali pano, mawonekedwe aukadaulo wama elevator pamsika wapadziko lonse lapansi amatengera ukadaulo wa elevator.Ukadaulo wama elevator okwera amawongolera gawo la msika wokwera kwambiri wa elevator ndi luso laukadaulo wama elevator othamanga kwambiri.Pakalipano, zikepe zapamwamba kwambiri padziko lonse lapansi ndi 28.5 metres pa sekondi imodzi, zofanana ndi 102 km pa ola, ndipo liwilo lapamwamba kwambiri la zikepe zapakhomo pano ndi 7 m / sec, lofanana ndi 25 km / h.
2.1.Kafukufuku wautali kwambiri waukadaulo wa elevator padziko lapansi
Nthawi yayitali kwambiri pakufufuza zaukadaulo wa elevator padziko lapansi ndiukadaulo wothamangitsira ma elevator panyumba zazitali.Kafukufuku waukadaulo adayamba mu 1970. Adaphunziridwa kwa zaka 45, ndipo ochita kafukufuku ku Europe, America ndi Japan sanachitepo kanthu mokulira.
2.2 ukadaulo womwe ukukula mwachangu kwambiri padziko lapansi
Kukula kwachangu kwaukadaulo wa elevator padziko lonse lapansi ndiukadaulo wamakompyuta woyendetsedwa ndi VVVF wowongolera pafupipafupi.Pambuyo pa ntchito ya 90s m'zaka zapitazi, pafupifupi onse ofukula zikepe ntchito microcomputer ulamuliro ndi VVVF pafupipafupi kutembenuka luso.
2.3 zongopeka kwambiri zaukadaulo wa elevator
Ukadaulo wapamwamba kwambiri wa elevator padziko lonse lapansi ndi chikepe chochokera padziko lapansi kupita kumalo okwerera mlengalenga komanso ukadaulo wa elevator kuchokera padziko lapansi kupita ku mwezi.
2.4 chikepe chomwe chikuyembekezeka kwambiri ku China m'zaka zisanu zikubwerazi
Tekinoloje ya elevator yomwe ikuyembekezeka kukwezedwa kwambiri ku China ndiyo chikepe chosungira mphamvu zosungira mphamvu komanso ukadaulo wosadukiza wamagetsi.Elevator ikugwirizana ndi dongosolo la State Council la 2014-2020 National Energy Development Strategy.Pambuyo pa kukwezedwa, kupulumutsa mphamvu ya elevator kudzathandizira kupulumutsa mphamvu kwa magetsi a Three Gorges (chikepe chokwanira kukweza mphamvu zopulumutsa mphamvu, kupulumutsa mphamvu pachaka kudzakhala zaka zisanu pambuyo pake. ”Mpaka madigiri 150 biliyoni).Chinthu china cha teknoloji ndi ntchito ya elevator mphamvu yosasunthika yomwe ingagwirizane nayo, ndipo ikhoza kupitiriza kugwira ntchito mwachizolowezi kwa ola limodzi pambuyo pa kulephera kwa mphamvu.Ukadaulowu umapangidwa ndi ma patent angapo ochokera ku Ningbo blue Fuji Elevator Co., Ltd., ndipo wayamba kuthandizira mabizinesi ena okwera kukwera ku Shanghai ndi Shanghai.
2.5 Ukadaulo wa elevator waku China womwe ukuyembekezeka kugwiritsidwa ntchito padziko lonse lapansi zaka khumi zikubwerazi
M'zaka khumi zikubwerazi, kugwiritsa ntchito kwambiri ukadaulo wa elevator waku China ndiukadaulo wa "high-rise building fire evacuation system".Nyumba zapadziko lapansi zikukulirakulira, Harry Fatah Da, nyumba yayitali kwambiri ku Dubai.
