傳菜式升降機(jī)的工作原理是液壓泵產(chǎn)生出高壓液壓油并推動(dòng)油缸活塞往復(fù)運(yùn)動(dòng)從而帶動(dòng)傳菜式升降機(jī)轎廂上下運(yùn)行。傳菜式升降機(jī)液壓油如果出現(xiàn)深褐色、乳雪白色、有異味的液壓油是變質(zhì)油，不可以使用的。干凈的傳菜式升降機(jī)液壓油應(yīng)該說(shuō)是液壓系統(tǒng)的生命，液壓系統(tǒng)中有很多精細(xì)部件，如果有固體雜質(zhì)入侵會(huì)造成油道堵塞等，危及液壓系統(tǒng)的安全運(yùn)行。
Chuan Cuisine lift pump works by generating a high-pressure hydraulic oil and push the cylinder piston reciprocates so as to drive the car to run up and down the lift pass dishes. Chuan dishes elevators hydraulic oil if there is a dark brown, milk white snow, the smell of deterioration of hydraulic oil is oil, it can not be used. Clean dishes lift pass hydraulic oil should be said that the life of the hydraulic system, hydraulic system, there are many fine parts, if there is solid impurities invasion will cause the oil duct blockage, endangering the safe operation of the hydraulic system.

傳菜式升降機(jī)液壓油在油泵、油缸內(nèi)流動(dòng)摩擦必然產(chǎn)生一定熱量，同時(shí)油箱內(nèi)的高溫也會(huì)向周圍空氣散發(fā)熱量。液壓系統(tǒng)是傳菜式升降機(jī)的心臟，液壓油是液壓系統(tǒng)的血液。
Chuan dishes elevators hydraulic oil pump, the fuel tank flow friction inevitably produce some heat, while the high temperature inside the tank will dissipate heat to the surrounding air. Hydraulic lift system is the transfer of cuisine in the heart of the hydraulic oil is the blood of the hydraulic system.

傳菜式升降機(jī)液壓油的理想工作溫度是30～50℃，實(shí)際要求的工作溫度小于70℃。
Chuan dishes elevators hydraulic oil ideal operating temperature is 30 ~ 50 ℃, the actual work required temperature is less than 70 ℃.
