1、液壓貨梯http://www.lxoz.cn/液壓系統(tǒng)中的細孔在進行運作時，此類部件消耗的動能將絕大部分轉變成熱能，從而導致油體升溫，溢流閥就是一個明顯的發(fā)熱體，在液壓貨梯氣壓裝置中流出的油體在經(jīng)過溢流閥的時候，油體溫度將大大升高。
Hydraulic freight elevator hydraulic system during operation of the pores, such components consume most of the kinetic energy will transform into heat, causing the oil to heat up the body, relief is an obvious heater, the outflow pressure in the hydraulic freight elevator device oil bodies after relief valve when the temperature of the oil bodies will be greatly increased.

2、液壓貨梯在油體流過連接部件時，將轉化為壓力，這部分壓力也將使油溫升高，液壓貨梯內(nèi)部發(fā)生泄漏，也有可能使得油體的溫度升高。
When the hydraulic pressure in the hydraulic oil flows through freight elevators connecting member, will be converted to pressure, this pressure will cause part of the oil temperature rise, the internal leakage of hydraulic freight elevators, it is possible that the temperature rise of the oil bodies.

3、液壓貨梯http://www.lxoz.cn/內(nèi)部的各個部件之間的摩擦也會轉變問熱能。
Various parts of the hydraulic lift  between internal heat will shift to ask.
