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