How to choose the right hydraulic boarding bridge如何正确选择合适的液压登车桥

液压登车桥主要有以下几个优点:

1、登车桥液压传动的各种元件,可以根据需要方便、灵活的来布置。

2、重量轻、体积小、运动惯性小、反应速度快。

3、操纵控制方便,可实现大范围的无极调速。

4、可自动实现过载保护。

5、一般采用矿物油作为工作介质,相对运动面可自行润滑,使用寿命长。

当然,液压移动登车桥也存在着一些缺点:

1、由于流体流动的阻力和泄露较大,所以效率较低。如果处理不当,泄露不仅污染场地,而且还可能引起火灾和爆炸事故。

2、由于工作性能易受到温度变化的影响,因此不宜在很高或很低的温度条件下工作。

3、液压元件的制造精度要求较高,因而价格较高。

4、由于液体介质的值泄露及可压缩性影响,不能得到严格的传动比。

   登车桥的种类很多,我们应正确的了解各种登车桥的优缺点,选择合适自己的登车桥。

Hydraulic boarding bridge has the following advantages:
Various components of the boarding bridge hydraulic transmission can be conveniently and flexibly arranged according to the needs.
Light weight, small size, low inertia, fast reaction speed.
The control is convenient and can realize wide range of stepless speed adjustment.
Automatic overload protection.
Generally, mineral oil is used as the working medium, which can be lubricated by itself relative to the moving surface and has a long service life.
Of course, hydraulic mobile boarding bridge also has some disadvantages:
Due to the large resistance and leakage of fluid flow, the efficiency is low. If not handled properly, the leak may not only pollute the site, but also cause fire and explosion accidents.
Because the working performance is easily affected by the temperature change, it is not suitable to work under the very high or very low temperature conditions.
The manufacturing accuracy of hydraulic components is higher, so the price is higher.
Due to the leakage of liquid media and the influence of compressibility, strict transmission ratio cannot be obtained.
There are many kinds of boarding Bridges, we should correctly understand the advantages and disadvantages of various boarding Bridges, choose suitable boarding Bridges of their own.
