isandulela
Amasistimu we-hydraulic kanye ne-lubrication adlala indima ebalulekile cishe kuyo yonke imishini emile nehambayo.Uketshezi ohlelweni ludlulisa amandla, lunikeze ukuthambisa, luthuthe ukushisa, futhi luvimbele ukugqwala.Izinga loketshezi luyisigxivizo seminwe salo lonke uhlelo.Isibonelo, ukulawulwa kwezinga lokushisa kanye nokuhlanzeka koketshezi yizici ezibalulekile esimweni semishini yokulawula iyonke ezinhlelweni eziphathwayo ze-hydraulic.Kuzo zonke izinhlelo ze-hydraulic, amandla ayaguqulwa futhi athuthwe.Okufana nokunyamalala ngendlela yokushisa.Umsebenzi wesistimu yokupholisa ukukhipha ukushisa.Uhlelo lokupholisa olusebenzayo lungasiza ukunweba impilo yoketshezi olusebenzayo nezihlungi ezisetshenziswayo futhi kunciphise izindleko zomjikelezo wempilo.
Indlela Yokubala Yokulahlekelwa Amandla (Amandla Okushisa).
Imodeli ekhethiwe kufanele ikwazi ukuhlangabezana nezidingo zokugeleza kwesistimu namandla okushisa ngesikhathi esifanayo.Ngokuvamile, ikhethwa ngendlela yokubala elandelayo.
Kufomula:
Pv=Ukuphelelwa Amandla [kw]
V = Amandla ethangi likawoyela [l]
Camafutha= Amandla Okushisa Alinganayo [kJ/kg K]
Ngamafutha Amaminerali: 1.88kJ/kg K
ρ amafutha= Ukuminyana kukawoyela [kg/I]
Ngamafutha Amaminerali: 0.915kg/I
△T=Ukunyuka Kwezinga Lokushisa Kohlelo【℃】
t=Isikhathi Sokusebenza【min】
P01= Amandla Okupholisa Alinganayo
T1=Izinga Lokushisa Likawoyela [°C]
T3=Izinga Lokushisa Le-Ambient【℃】
η1 = Isici Sokuphepha Samandla Okudlulisa Ukushisa
Ngokuvamile, thatha i-1.1
1. Indlela yokubala yokulahlekelwa amandla
Bala ukulahlekelwa kwamandla ezinto ezisetshenziswayo ezikhona, bese ubala ukulahleka kwamandla ngokuya ngokukhuphuka kwezinga lokushisa likawoyela ngokukala ukukhuphuka kwezinga lokushisa lamafutha phakathi nenkathi ethile yesikhathi.Ngokuvamile kutholakala ngale ndlela elandelayo:
Pv=△T*C uwoyela*P uwoyela V/T/60 (kW)
Isibonelo: Linganisa izinga lokushisa likawoyela wesistimu ye-hydraulic ekhuphuka ukusuka ku-20 ° C kuya ku-45 ° C phakathi nemizuzu engu-20, umthamo wethangi lamafutha ngu-600L, futhi izinga lokugeleza kwesistimu: 200 L / min.
Amandla e-thermal akhiqizwayo yilawa:
Pv=25*1.88*0.915*600/20/60≈21.5 (kW)
Bese ubala amandla okupholisa alinganayo ngokwezinga lokushisa likawoyela elilindeleke kakhulu ekusebenzeni okujwayelekile kwesistimu:
P01=Pv/(T1-T3)*η1(kW/℃)
Uma sicabanga ukuthi izinga lokushisa eliphezulu elilindelekile likawoyela ohlelweni ngu-55°C, izinga lokushisa lendawo ngaleso sikhathi lingu-35°C.
P01=21.5/(55-35)*1.1≈1.2 (kW/℃)
Kunconywa ukuthi ucabangele i-10% yemajini yokuphepha P01*1.1
P01=1.2*1.1=1.32 (Kw/℃)
Okusho ukuthi: kukhona ukulahlekelwa kwamandla angu-1.32kW/℃ azohlakazwa ngesipholile somoya.
INDLELA YOKUKHETHA OKUPHOLISA komoya
Uma izinga lokugeleza lingu-200L/min, amandla okupholisa alinganayo ngu-1.32kW/℃.
Ngokusho kwegrafu, uma izinga lokugeleza lingu-200L/min, amandla okupholisa alinganayo alingana no-1.32kW/℃ noma ngaphezulu kuka-1.32kW/℃.Imodeli ekhethiwe yi-DXT-8.
Uma isipholile sohlobo lwe-DXT-8 sangempela sinesilinganiso sokugeleza esingu-200L/min, amandla okupholisa alinganayo ngu-1.55kW/℃.
1.55kW/℃>1.32kW/℃
