There are so many suppliers of suspension hydraulic props on the market. How to choose quality suppliers? As a professional editor I summarized the characteristics of the suspension hydraulic props of China Coal Group, which is used as a reference for customers at the time of purchase:
1. Using the mining Suspension Hydraulic Props technology principle, the suspension force of the pillar reaches four-fifths of the working resistance, and the force of the column is only one-fifth. Thereby, the stability and safety of the pillars are greatly improved, and the support height, load bearing capacity and anti-offset capability of the pillars are improved.
2. The mining Suspension hydraulic props abandon the elongated column, the column head and the piston, no arc welding, no internal leakage, visual inspection with the naked eye, once the pillar is leaked, the pillar can be replaced at any time, so that the pillar becomes It is safer and avoids the pillars and cumbersome inspection work caused by the internal leakage of the pillars.
3. The three-purpose valve for mining Suspension hydraulic prop is designed on the handlebar body. When the liquid is injected, the three-purpose valve does not rise with the living column, which increases the working stroke of the pillar. One specification can replace the DZ-type pillar 2 ~ 4 specifications, easy underground management and use, reducing the labor intensity of miners.
4. The sealing points of the mining Suspension hydraulic props are sealed and tightened. The replacement of the seals is very convenient. The assembly and disassembly and maintenance are simple, and only the damaged parts need to be replaced.
5, The mining Suspension hydraulic props using nickel-phosphorus-boron electroless plating surface treatment technology, anti-corrosion, strong wear resistance, can use downhole neutral water as working medium, is an environmentally-friendly pillar equipment.
6. The living column adopts the original heat treatment processing technology, which improves the product's anti-cannon collapse, anti-mechanical damage and anti-bending ability, reduces the maintenance of the pillars, and improves the safety of the products.
