Tahlehelo ea Matla (Mocheso oa Mocheso) Mokhoa oa ho Bala

Mohlala o khethiloeng o tlameha ho khona ho finyella litlhoko tsa tsamaiso ea tsamaiso le matla a ho futhumatsa ka nako e le 'ngoe.Ka kakaretso, e khethoa ka mokhoa o latelang oa ho bala. 

Ka foromo:

P_v=Tahlehelo ea Matla [kw]

V = Bokhoni ba Tanka ea Oli [l]

C_oli= Bokhoni bo lekanang ba Mocheso [kJ/kg K]

Bakeng sa Oli ea Liminerale: 1.88kJ/kg K

ρ _oli= Boima ba oli [kg/I]

Bakeng sa Oli ea Liminerale: 0.915kg/I

△T=Ho phahama ha Mocheso oa Sistimi【℃】

t=Nako ea ho sebetsa【min】

P₀₁= Matla a ho Pholisa a Tšoanang

T1=Mocheso o Lebeletsweng wa Oli [°C]

T3=Mocheso o Tletseng【℃】

η1 = Ntlha ea Tšireletseho ea Matla a Ho Fetisetsa Mocheso

Ka kakaretso, nka 1.1

1. Mokhoa oa ho bala tahlehelo ea matla

Bala tahlehelo ea matla a lisebelisoa tse teng, 'me u bale tahlehelo ea matla ho latela ho phahama ha mocheso oa oli ka ho lekanya ho phahama ha mocheso oa oli ka nako e itseng.Hangata e fumanoa ka tsela e latelang:

P_v=△T*C oli*P oli V/T/60 (kW)

Mohlala: Lekanya mocheso oa oli oa tsamaiso ea hydraulic e nyolohang ho tloha ho 20 ° C ho ea ho 45 ° C nakong ea metsotso ea 20, matla a tanka ea oli ke 600L, 'me tekanyo ea tsamaiso ea tsamaiso ke: 200 L / min.

Matla a futhumatsang a hlahisoang ke:

P_v=25*1.88*0.915*600/20/60≈21.5 (kW)

Ebe u bala matla a ho futhumatsa a lekanang ho latela mocheso oa oli o lebelletsoeng ka ho fetesisa bakeng sa ts'ebetso e tloaelehileng ea sistimi:

P₀₁=P_v/(T1-T3)*η₁(kW/℃)

Ho nka hore mocheso o nepahetseng oa oli o lebelletsoeng bakeng sa sistimi ke 55°C, mocheso o teng ka nako eo ke 35°C.

P₀₁=21.5/(55-35)*1.1≈1.2 (kW/℃)

Ho khothaletsoa ho nahana ka karolo ea 10% ea polokeho ea P₀₁*1.1

P₀₁=1.2*1.1=1.32 (Kw/℃)

Ke hore: ho na le tahlehelo ea matla ea 1.32kW/℃ e lokelang ho felloa ke moea o pholileng.
