Cad iad na hairíonna a bhaineann le teirmeastat carr briste?

Mura féidir teirmeastat a oscailt, taispeánfaidh an teirmiméadar go bhfuil teocht an uisce sa limistéar ardteochta, ach ní chasann an lucht leanúna san umar uisce, tá teocht an innill ard, agus is furasta an fhrithshuim a bheith ann .

Mura ndúntar an teirmeastat gluaisteán, méadóidh teocht an uisce go mall, go háirithe sa gheimhreadh, nuair a bhíonn teocht an uisce fós sa chrios teochta íseal do 10-20 nóiméad, beidh an luas réchasta ard .

Thermostat is an automatic temperature-regulating device, which usually contains temperature-sensing components. It opens and turns off the flow of coolant by expanding or contracting. That is to say, it automatically adjusts the amount of water entering the radiator according to the temperature of the coolant and changes the circulating range of the coolant in order to regulate the cooling capacity of the cooling córas .

At present, the main thermostat used is the wax thermostat, which is controlled by the internal paraffin through the principle of thermal expansion and contraction. When the cooling temperature is lower than the prescribed value, the refined paraffin in the thermostat temperature sensor body is solid, the thermostat valve closes the passage between the engine and the radiator under the action of the spring, and the coolant returns Chun an t -inneall tríd an gcaidéal le haghaidh cúrsaíochta beag san inneall . Nuair a shroicheann an teocht chuisnithe an luach forordaithe, tosaíonn an pairifín ag leá agus de réir a chéile éiríonn sé leacht . Méadaíonn toirt na pairifín agus méadaíonn an feadán rubber brú suas go dtí an tslat brúite, agus tá an tslat brúite, agus an tslat brúite, an t -an tslat, an t -an tslat a bhrúnn an t -an tslat, an t -an t -an t -an tslat, an t -an t -an t -an tslat a bhrúnn an t -an t -an t -an t -an tslat seo an tslat an tslat a bhfuil an tslat é a bheith ag iarraidh go bhfuil sé ina Comhla ar gcúl chun an comhla {. a oscailt ag an am seo, téann an chuisneoir ar ais go dtí an t -inneall tríd an radaitheoir agus an comhla teirmeastat, agus ansin tríd an gcaidéal le haghaidh cúrsaíochta mór . Socraítear an chuid is mó de na teirmeastaití i bpíobán asraon an chinn sorcóra, a bhfuil na haisbhuntáistí de dhíspreagadh agus de dhíspreagadh na mboilgeog i gcinn an fhuaraithe i gceann an chinn fuaraithe, i ndíchruthú na mboilgles a dhíspreagadh sa chinn, chun an t -abhcóidí a dhíspreagadh de dhíspreagadh an aeir i gcinn an tsorcóra a dhíspreagadh i gceann an tsorcóra, Córas . Is é an míbhuntáiste ná go mbíonn na teirmeastait oscailte agus dúnta go minic nuair a bhíonn siad ag obair, agus mar thoradh air sin tá ascalaithe .

When the engine working temperature is low (below 70℃C), the thermostat automatically closes the access to the radiator, and opens the access to the pump. The cooling water from the water jacket enters the pump directly through the hose, and is fed into the water jacket through the pump for recycling. Because the cooling water does not radiate from the radiator, the engine working temperature can rise rapidly. This circulation route is called small circulation. When the working temperature of the engine is high (above 80℃C), the thermostat automatically closes the passage to the pump, and opens the passage to the radiator. The cooling water from the water jacket is radiated by the radiator and then sent into the water jacket by the water pump, which improves the cooling déine chun an t -inneall a chosc ó róthéamh . Tugtar timthriall mór ar an mbealach cúrsaíochta seo . Nuair a bhíonn teocht oibre an innill idir 70 80 C, timthriallta móra agus beaga cómhalartú, is é sin, cuid de na ciorcail bheaga}}} i dtimthriallta móra agus an chuid eile de na ciorcail uisce fuaraithe}}}}}} an chuid eile den chuid den uisce fuaraithe ciorcail uisce i gciorcail uisce i dtimthriallta}}} den chuid den chuid den fhuarú ciorcail ciorcail}}}}}}}}}}} \\ T

Is é feidhm an teirmeastat gluaisteán a dhúnadh sula bhfuil teocht an chairr bainte amach ag an am seo, téann an sreabhán fuaraithe den inneall ar ais chuig an inneall tríd an caidéal uisce agus scaipeann sé san inneall chun an t -inneall a théamh suas go tapa . nuair a bhíonn an t -uisce á ithir go tapa, is féidir leis an gciorcal uisce a chiorrú go tapa, agus é mar sin go n -osclaíonn an t -uisce, mar sin go bhfuil an t -uisce ábalta agus go n -éireoidh leis an gcorn. teas .
