Isishwankathelo
Ivalvu yokulawula yinxalenye yolawulo kwinkqubo yokuhambisa ulwelo, enemisebenzi yokunqamla, ukulawula, ukuphambukisa, ukuthintela ukuhamba kwamanzi emva, ukuzinzisa i-voltage, ukuphambukisa okanye ukugcwala kwamanzi kunye nokunciphisa uxinzelelo. Iivalvu zolawulo lwemizi-mveliso zisetyenziswa kakhulu kulawulo lwenkqubo kwizixhobo zoshishino kwaye zezemizi-mveliso yezixhobo, izixhobo kunye ne-automation.
1. Ivalvu yokulawula ifana nengalo yerobhothi kwinkqubo yokwenza i-automation yemizi-mveliso, kwaye yinto yokugqibela yokulawula yokutshintsha iiparameter zenkqubo ezifana nokuhamba okuphakathi, uxinzelelo, ubushushu, kunye nenqanaba lolwelo. Ngenxa yokuba isetyenziswa njenge-terminal actuator kwinkqubo yolawulo lwenkqubo ye-automation yemizi-mveliso, ivalvu yokulawula, ekwaziwa ngokuba yi-"actuator", yenye yezona zixhobo ziphambili zokwenza izinto ngobuchule.
2. Ivalvu yokulawula yeyona nto iphambili kwi-automation yemizi-mveliso. Inqanaba layo lophuhliso lobuchwephesha libonisa ngokuthe ngqo amandla okuvelisa izixhobo ezisisiseko zelizwe kunye nenqanaba lokuhlaziya imizi-mveliso. Yimeko efunekayo kwimizi-mveliso esisiseko kunye namashishini ayo asezantsi okusebenzisa ukuze kufezekiswe ubukrelekrele, uthungelwano kunye noomatshini. Iivalvu zokulawula ngokubanzi zenziwe zii-actuators kunye neevalvu, ezinokuhlelwa ngokwemisebenzi, iimpawu ze-stroke, amandla asetyenziswa yi-actuator exhotyisiweyo, uluhlu loxinzelelo, kunye nobubanzi bobushushu.
Ikhonkco lemizi-mveliso
Ishishini leevalvu zokulawula eliphambili liquka intsimbi, iimveliso zombane, izinto ezahlukeneyo ezidityanisiweyo, izinto zokugquma, izinto zokubopha kunye nezinye izinto zokwenza imveliso zoshishino. Kukho inani elikhulu lamashishini aphambili, ukhuphiswano olwaneleyo kunye nobonelelo olwaneleyo, olubonelela ngemeko elungileyo esisiseko yokuveliswa kwamashishini eevalvu zokulawula; Uluhlu olubanzi lwezicelo ezisezantsi, kubandakanya ipetroli, i-petroleum, i-petrochemical, i-chemical, iphepha, ukhuseleko lokusingqongileyo, amandla, ukumbiwa kwemigodi, i-metallurgy, amayeza kunye namanye amashishini.
Ngokwembono yokwabiwa kweendleko zemveliso:
Izinto ezisetyenziswa kudala ezifana nentsimbi, iimveliso zombane kunye nezinto ezisetyenziswa kudala zingaphezulu kwe-80%, kwaye iindleko zokuvelisa zimalunga ne-5%.
Eyona ndawo inkulu yokusebenzisa iivalvu zolawulo eTshayina yishishini leekhemikhali, elingaphezulu kwe-45%, lilandelwe yimizi-mveliso yeoyile negesi kunye nombane, elingaphezulu kwe-15%.
Ngokuphuculwa kwetekhnoloji yokulawula yemizi-mveliso kwiminyaka yakutshanje, ukusetyenziswa kweevalvu zokulawula ekwenzeni amaphepha, ukhuseleko lokusingqongileyo, ukutya, amayeza kunye nezinye iinkalo nako kukhula ngokukhawuleza nangokukhawuleza.
Ubungakanani boshishino
Uphuhliso lwemizi-mveliso yaseTshayina luyaqhubeka nokuphucuka, kwaye inqanaba le-automation yemizi-mveliso liyaqhubeka nokuphucuka. Ngo-2021, ixabiso elongezelelekileyo lemizi-mveliso yaseTshayina liza kufikelela kwi-37.26 trillion yuan, ngesantya sokukhula se-19.1%. Njengento yolawulo lwesiphelo senkqubo yolawulo lwemizi-mveliso, ukusetyenziswa kwevalvu yokulawula imizi-mveliso kwinkqubo yolawulo lwemizi-mveliso kuphucula ngokufanelekileyo uzinzo, ukuchaneka kunye nokuzenzekelayo kwenkqubo yolawulo. Ngokwedatha yeShanghai Instrument Industry Association: ngo-2021, inani lamashishini enkqubo yolawulo lwe-automation yemizi-mveliso eTshayina liza kunyuka ngakumbi liye kwi-1,868, ngengeniso ye-368.54 yeebhiliyoni zeeyuan, ukunyuka konyaka nge-30.2%. Kwiminyaka yakutshanje, imveliso yeevalvu zokulawula imizi-mveliso eTshayina inyuke unyaka nonyaka, ukusuka kwi-9.02 yezigidi zeeseti ngo-2015 ukuya kwi-17.5 yezigidi zeeseti ngo-2021, ngesantya sokukhula sonyaka esidibeneyo se-6.6%. ITshayina ibe ngomnye wabavelisi abakhulu be-valvu zokulawula imizi-mveliso kwihlabathi.
Imfuno yeevalvu zolawulo lwemizi-mveliso kumashishini asezantsi afana neekhemikhali, ioyile kunye negesi iyaqhubeka nokukhula, ikakhulu kubandakanya iinkalo ezine: iiprojekthi zotyalo-mali ezintsha, utshintsho lobuchwephesha kwiiprojekthi ezikhoyo, ukutshintshwa kweendawo ezisele, kunye neenkonzo zokuhlola nokugcina. Kwiminyaka yakutshanje, ilizwe lihlengahlengise isakhiwo semizi-mveliso kwaye laguqula uqoqosho. Indlela yokukhula kunye nokukhuthazwa ngamandla kolondolozo lwamandla kunye namanyathelo okunciphisa ukukhutshwa komoya kunempembelelo ecacileyo yokukhuthaza utyalo-mali lweprojekthi kunye neemfuno zotshintsho lwetekhnoloji kumashishini asezantsi. Ukongeza, uhlaziyo oluqhelekileyo kunye nokutshintshwa kwezixhobo kunye neenkonzo zokuhlola kunye nokugcina nazo zizise imfuno ezinzileyo yophuhliso lwemizi-mveliso. Ngo-2021, ubungakanani bemarike yeevalvu zolawulo lwemizi-mveliso yaseTshayina buya kuba malunga ne-39.26 yeebhiliyoni zeeyuan, ukunyuka konyaka nonyaka okungaphezulu kwe-18%. Eli shishini linenzuzo ephezulu kunye nenzuzo enamandla.
Ipateni yeshishini
