Mining production is a widespread concern in the development of society today. Therefore, the existence of various machinery and equipment provides support and assistance to the production of enterprises. Among them, the hydraulic prop is an important existence for the safe production of mining. The specific distinction skills, I hope you understand the following knowledge.
How to choose a hydraulic props?
There are two types of oil cylinders, hot-rolled tubes (quenched and tempered) and cold-drawn tubes. Although the cold-drawn tubes are smoother and more beautiful on the surface, the hardness of the cold-drawn tubes will change after being stretched, and the ability to carry pressure will also reduce. This is not the case for hot-rolled pipes. The material can be cut as much as required. The thickness of the pipe wall is always the same, and the ability to bear pressure is high.
The inner wall of the oil cylinder, in order to reduce the corrosion of the hydraulic prop during use, will choose copper plating on the inner wall during production. Its corrosion resistance depends on the thickness of the copper plating. Check the copper layer on the inner wall of the hydraulic prop. Thickness, you can basically understand the corrosion resistance and service life of the hydraulic prop.
In order to wear-resistant, the outer wall of the living cylinder needs chrome plating, and the monomer without chrome plating is easy to wear, which brings some unsafe factors.
The selection of hydraulic props according to the above three points provides support and assistance for the smooth installation and use of machinery and equipment and the improvement of mining production efficiency.
