Nhau dzeTekinoroji｜Maitiro eKusarudza Mhepo Inotonhorera Kubva pane Kurasa Simba

Jiangsu HELIKE Fluid Technology Co., Ltd.inotsigira-ine-yakazara yeDongxu Hydraulics.Iyo yakakosha mukutsvagisa nekusimudzira, dhizaini, kugadzirwa uye kutengesa kwealuminium plate-fin heat exchangers.

Hydraulic uye lubrication masisitimu anoita basa rakakosha mune angangoita ese akamira uye enhare michina.Mvura iri muhurongwa inofambisa simba, inopa lubrication, inotakura kupisa, uye inodzivirira kuora.Hunhu hwemvura ndiyo minwe yehurongwa hwese.Semuyenzaniso, kudzora tembiricha uye kuchena kwemvura zvinhu zvakakosha mune yakazara kudzora michina mamiriro mune mobile hydraulic application.Mune ese ma hydraulic system, simba rinoshandurwa uye kutakurwa.Zvakadai sokunyangarika muchimiro chekupisa.Basa rekugadzirisa kutonhora kubvisa kupisa.Iyo inoshanda yekutonhodza sisitimu inogona kubatsira kuwedzera hupenyu hwemvura inoshanda uye mafirita anoshandiswa uye kuderedza mutengo wehupenyu.

Kupera Simba (Kupisa Simba) Kuverengera Method

Muenzaniso wakasarudzwa unofanirwa kukwanisa kuzadzisa zvinodiwa zvehurongwa hwekuyerera uye kupisa simba panguva imwe chete.Kazhinji, inosarudzwa nenzira inotevera yekuverenga. 

Mune formula:

P_v=Kupera kweSimba [kw]

V = Oiri Tangi Kukwanisa [l]

C_mafuta= Yakaenzana Kupisa Kwesimba [kJ/kg K]

Kumafuta echicherwa: 1.88kJ/kg K

ρ _mafuta= Kuwanda kwemafuta [kg/I]

KuMineral Oiri: 0.915kg/I

△T = Kukwira kweTembiricha yeSitimu【℃】

t=Nguva Yekushanda【min】

P₀₁= Yakaenzana Kutonhodza Simba

T1=Tembiricha Yemafuta Inotarisirwa [°C]

T3=Ambient Temperature【℃】

η1 = Chengetedzo Factor yeHeat Transfer Simba

Kazhinji, tora 1.1

1. Simba kurasikirwa kukarukureta nzira

Verenga kurasikirwa kwemagetsi emidziyo iripo, uye verenga kurasikirwa kwemagetsi zvinoenderana nekukwira kwekushisa kwemafuta nekuyera kukwira kwekushisa kwemafuta mukati meimwe nguva yenguva.Kazhinji inowanikwa sezvinotevera:

P_v=△T*C mafuta*P mafuta V/T/60 (kW)

Muenzaniso: Kuyera kutonhora kwemafuta e hydraulic system inokwira kubva ku20 ° C kusvika 45 ° C mukati memaminitsi makumi maviri, kukwanisa kwetangi yemafuta ndeye 600L, uye chiyero chekuyerera: 200 L / min.

Thermal simba rinogadzirwa ndeiyi:

P_v=25*1.88*0.915*600/20/60≈21.5 (kW)

Wobva waverenga yakaenzana simba rekutonhodza zvinoenderana neakanakisa-inotarisirwa tembiricha yemafuta kune yakajairika mashandiro ehurongwa:

P₀₁=P_v/(T1-T3)*η₁(kW/℃)

Tichifunga kuti tembiricha yemafuta inotarisirwa kuita 55°C, tembiricha yepakati panguva iyoyo i35°C.

P₀₁=21.5/(55-35)*1.1≈1.2 (kW/℃)

Zvinokurudzirwa kufunga nezve 10% yekuchengetedza margin P₀₁*1.1

P₀₁=1.2*1.1=1.32 (Kw/℃)

Ndiko kuti: pane kurasikirwa kwesimba kwe1.32kW/℃ kuti iparadzwe kuburikidza nemhepo inotonhorera.

AIR COOLER SELECTION METHOD

Kana kuyerera kuri 200L/min, simba rekutonhodza rakaenzana ndere: 1.32kW/℃.

Zvinoenderana negirafu, kana kuyerera kuri 200L/min, simba rekutonhora rakaenzana rakaenzana ne1.32kW/℃ kana kupfuura 1.32kW/℃.Iyo yakasarudzwa modhi iDXT-8.

Kana iyo chaiyo DXT-8 mhando inotonhorera ine kuyerera kwe200L/min, yakaenzana simba rekutonhodza i1.55kW/℃.

1.55kW/℃>1.32kW/℃
