液壓貨梯http://m.meilijh.com/是靠液壓缸提供動(dòng)力驅(qū)動(dòng)工作臺(tái)的升降,，由結(jié)構(gòu)原理和工作特點(diǎn)所決定,，在工作臺(tái)攜帶著貨物和工件上升時(shí)，需要液壓缸向其提供驅(qū)動(dòng)力,，即液壓缸輸出能量,，把機(jī)械(液壓)能轉(zhuǎn)換成勢(shì)能,；而在工作臺(tái)攜帶著工件下降時(shí)，重物的勢(shì)能將被釋放出來(lái),。
Hydraulic freight elevator is driven by a hydraulic cylinder powered lift table, as determined by the characteristics of the structure and working principle, at the table when carrying cargo and artifacts to rise, the need to provide the driving force of the hydraulic cylinder, hydraulic cylinder that output energy, the mechanical (hydraulic) energy is converted to potential energy; in the table carrying the workpiece is decreased, the weight of the potential energy will be released.

因此液壓貨梯在設(shè)計(jì)其液壓系統(tǒng)時(shí),，應(yīng)考慮勢(shì)能回收，把工作臺(tái)下降過(guò)程中釋放出的勢(shì)能轉(zhuǎn)變成液壓能,，并在上升時(shí)加以利用,，以減少無(wú)用功的消耗，提高能量的利用效率,，并同時(shí)達(dá)成使系統(tǒng)運(yùn)行平穩(wěn),、工作安全可靠、結(jié)構(gòu)簡(jiǎn)單,、效率高,、便于設(shè)計(jì)和應(yīng)用。
Therefore, in the design of hydraulic freight elevator hydraulic system, you should consider the potential recovery, the decline bench during the release of potential energy into hydraulic energy, and use it when you rise, in order to reduce the consumption of wasted effort to improve the efficiency of energy use, and Meanwhile reach so smooth system operation, safe and reliable, simple structure, high efficiency, ease of design and applications.

The drop table hydraulic freight elevators released during hydraulic energy into potential energy, and the use of the accumulator to store it, to achieve energy recovery. When the table to rise again, to pump oil accumulator, so the rise again during the hydraulic pump motor power consumption reduction, to save energy. Due to hydraulic freight elevator movement only in the vertical direction, the decline can be realized by means of gravity, in order to simplify the structure of the hydraulic cylinder, lower manufacturing costs, the use of a single-acting cylinder; large lift travel generally requires the use of two hydraulic cylinders, and requires two-cylinder synchronous .
