With the emergence of hydraulic elevators, the technology of installing hydraulic elevators is simpler. As long as the hydraulic elevators are set flush with the roof, the lifting function can be realized. What are the advantages and disadvantages of hydraulic elevators? What are the components of hydraulic elevators? Qiyun will make a comprehensive introduction for you!

液壓電梯優(yōu)缺點(diǎn)

Advantages and disadvantages of hydraulic elevator

一、早期的液壓電梯是什么樣的？

1、 What was the early hydraulic elevator like?

早期的液壓電梯的傳動(dòng)介質(zhì)是水，利用水的不可壓縮特性通過(guò)加壓提高水的壓力，將帶有一定壓力的水接入缸體內(nèi)，推動(dòng)缸體內(nèi)的柱塞頂升轎廂，使轎廂向上運(yùn)行；通過(guò)泄流閥開(kāi)啟泄流，轎廂在自重的作用下下降。但由于水壓含有氣泡會(huì)產(chǎn)生波動(dòng)及缸體生銹問(wèn)題難以解決，之后就用油為媒介驅(qū)動(dòng)柱塞做直線運(yùn)動(dòng)。由于液壓電梯提升力大、可以提供較高的機(jī)械效率且能耗較低，因此對(duì)于短行程、重載荷的場(chǎng)合，使用優(yōu)點(diǎn)尤為明顯。

The transmission medium of early hydraulic elevators was water. Using the incompressible characteristics of water, the pressure of water was increased by pressurization, and the water with a certain pressure was introduced into the cylinder to push the plunger in the cylinder to lift the car and make the car run upward; Open the discharge valve and the lift car will descend under the action of its own weight. However, because the water pressure containing bubbles will produce fluctuations and the cylinder block rust problem is difficult to solve, then oil is used as the medium to drive the plunger to do linear motion. Because the hydraulic elevator has large lifting force, can provide high mechanical efficiency and low energy consumption, it has obvious advantages for short stroke and heavy load occasions.

二、液壓電梯的組成有哪些？

2、 What are the components of hydraulic elevators?

液壓電梯是由：泵站系統(tǒng)、液壓系統(tǒng)、導(dǎo)向系統(tǒng)、轎廂、門(mén)系統(tǒng)、電氣控制系統(tǒng)、保護(hù)系統(tǒng)等組成，并不是簡(jiǎn)易升降機(jī)。液壓電梯具有底坑淺、無(wú)需機(jī)房、井道利用率高、不會(huì)墜梯等優(yōu)點(diǎn)。

The hydraulic elevator is composed of pump station system, hydraulic system, guiding system, lift car, door system, electrical control system, safety protection system, etc. it is not a simple elevator. The hydraulic elevator has the advantages of shallow pit, no machine room, high shaft utilization and no falling.

三、液壓電梯優(yōu)缺點(diǎn)分別是什么？

3、 What are the advantages and disadvantages of hydraulic elevators?

液壓的優(yōu)點(diǎn)：

Advantages of hydraulic pressure:

1、液壓傳動(dòng)的各種元件，可以根據(jù)需要方便、靈活地來(lái)布置。

1. Various components of hydraulic transmission can be conveniently and flexibly arranged according to needs.

2、重量輕、體積小、運(yùn)動(dòng)慣性小、反應(yīng)速度快 。

2. Light weight, small volume, small inertia and fast reaction speed.

3、操縱控制方便，可實(shí)現(xiàn)大范圍的無(wú)級(jí)調(diào)速（調(diào)速范圍達(dá)2000：1）。

3. It is easy to operate and control, and can realize a wide range of stepless speed regulation (speed regulation range up to 2000:1).

液壓的缺點(diǎn)：

Disadvantages of hydraulic pressure:

1、由于流體流動(dòng)的阻力和泄露較大，所以效率較低。如果處理不當(dāng)，泄露不僅污染場(chǎng)地，而且還可能引起火災(zāi)和爆炸事故。

1. Due to the large resistance and leakage of fluid flow, the efficiency is low. If handled improperly, the leakage will not only pollute the site, but also cause fire and explosion accidents.

2、由于工作性能易受到溫度變化的影響，因此不宜在很高或很低的溫度條件下工作。

2. Since the working performance is easily affected by temperature changes, it is not suitable to work at very high or low temperatures.

3、液壓元件的制造精度要求較高，因而較貴。

3. The manufacturing accuracy of hydraulic components is high, so the price is expensive.
