Jiangsu HELIKE Fluid Technology Co., Ltd.He lālā paʻa ia o Dongxu Hydraulics.He mea kūikawā ia i ka noiʻi a me ka hoʻomohala ʻana, ka hoʻolālā ʻana, ka hana ʻana a me ke kūʻai aku ʻana i nā mea hoʻololi wela alumini plate-fin.
E kālele ana i ka ʻenekinia/mekini ʻoihana kiʻekiʻe kiʻekiʻe o ka ʻaila hoʻoheheʻe ea
olelo mua
He kuleana koʻikoʻi nā ʻōnaehana hydraulic a lubrication ma kahi kokoke i nā mīkini paʻa a me nā mīkini paʻa.Hoʻouna ka wai i loko o ka ʻōnaehana i ka mana, hāʻawi i ka lubrication, lawe i ka wela, a pale i ka corrosion.ʻO ka maikaʻi o ka wai ka manamana lima o ka ʻōnaehana holoʻokoʻa.No ka laʻana, ʻo ka mālama ʻana i ka mahana a me ka maʻemaʻe o nā wai he mau kumu nui i ke kūlana o nā lako mana holoʻokoʻa i nā noi hydraulic mobile.I nā ʻōnaehana hydraulic āpau, hoʻololi ʻia ka ikehu a lawe ʻia.E like me ka nalo ʻana ma ke ʻano o ka wela.ʻO ka hana o ka ʻōnaehana hoʻoluʻu e wehe i ka wela.Hiki i ka ʻōnaehana hoʻoluʻu maikaʻi ke kōkua i ka hoʻonui ʻana i ke ola o ka wai hana a me nā kānana i hoʻohana ʻia a hoʻemi i nā kumukūʻai o ke ola.
Ke Kaʻina Helu (Heat Power).
Pono e hiki i ke kŘkohu koho ke hoʻokō i nā koi o ka holo ʻana o ka ʻōnaehana a me ka mana wela i ka manawa like.ʻO ka maʻamau, koho ʻia e ke ʻano helu helu.
Ma ka papa kuhikuhi:
Pv= Pohō Mana [kw]
V = Kaha Pahu ʻaila [l]
Caila= Hikina wela like [kJ/kg K]
No ka ʻaila ʻaila: 1.88kJ/kg K
ρ aila= ʻAila ʻAila [kg/I]
No ka Aila Minerala: 0.915kg/I
△T=Ke piʻi ʻana o ka wela o ka ʻōnaehana【℃】
t=Ka manawa hana【min】
P01= Mana Hooluu Kaulike
T1=Mahina aila i manaʻo ʻia [°C]
T3=Mahana wela【℃】
η1 = Ke kumu palekana o ka mana hoʻoili wela
ʻO ka maʻamau, lawe i ka 1.1
1. Keʻano helu mana poho
E helu i ka nalowale o ka mana o nā mea hana e kū nei, a e helu i ka nalowale o ka mana e like me ka piʻi ʻana o ka mahana o ka ʻaila ma ke ana ʻana i ka piʻi ʻana o ka ʻaila i loko o kekahi manawa.Loaʻa pinepine ia penei:
Pv=△T*C aila*P aila V/T/60 (kW)
Ka Laʻana: E ana i ka mahana aila o kahi ʻōnaehana hydraulic e piʻi ana mai 20 ° C a i 45 ° C i loko o 20 mau minuke, ʻo 600L ka mana o ka pahu aila, a ʻo ke kahe o ka ʻōnaehana: 200 L / min.
ʻO ka mana wela i hana ʻia:
Pv=25*1.88*0.915*600/20/60≈21.5 (kW)
A laila e helu i ka mana hoʻoluʻu like e like me ka mahana ʻaila maikaʻi loa i manaʻo ʻia no ka hana maʻamau o ka ʻōnaehana:
P01=Pv/(T1-T3)*η1(kW/℃)
Ke manaʻo nei he 55°C ka mahana o ka aila i manaʻo ʻia no ka ʻōnaehana, ʻo 35°C ka mahana ambient i kēlā manawa.
P01=21.5/(55-35)*1.1≈1.2 (kW/℃)
Manaʻo ʻia e noʻonoʻo i kahi palena palekana 10% P01*1.1
P01=1.2*1.1=1.32 (Kw/℃)
ʻO ia hoʻi: loaʻa ka mana o 1.32kW/℃ e hoʻopau ʻia ma o ka mea hoʻoluʻu ea.
KANAWAI KOHO AIR COOLER
I ka 200L / min ka kahe kahe, ʻo ka mana hoʻomaha like: 1.32kW / ℃.
Wahi a ka pakuhi, inā he 200L/min ka nui o ke kahe, ua like ka mana hoʻomaha like me 1.32kW/℃ a ʻoi aku paha ma mua o 1.32kW/℃.ʻO ke kumu hoʻohālike i koho ʻia ʻo DXT-8.
Ke loaʻa i ka DXT-8 ʻano mea hoʻoluʻu maoli ke kahe kahe o 200L/min, ʻo ka mana hoʻoluʻu like ʻo 1.55kW/℃.
1.55kW/℃>1.32kW/℃
