Suspension type single hydraulic props have strong anti-eccentricity and greater stability, use neutral water, reduce costs, low repair and maintenance costs, more convenient to use, more convenient to carry; high stability. Suspension single hydraulic prop is suitable for roof support of coal mining face, end roof support of fully mechanized mining face, advanced support for roadway tunneling.
Technical principle of suspension type single hydraulic prop:
The viability of the column that stabilizes the oil pressure directly passes through the lid acting on the inner cavity of the column. The unstable support of the oil pressure makes the resistance force sharing the work around 405. Alive, the pressure on the shaft of the column is only one hundred and fifty. One point, to improve the stability and safety of the column, but also to increase the height and bearing capacity of the column. At present, the domestic and foreign monomer liquid concrete pillar products are based on the principle of piston technology, and make full use of the apparent resistance of the turbid liquid pressure column to share the work. The column cannot bear all the work of resistance, which is often transported away. It was an accident on the roof.
The arc welding gaps that are difficult to ensure in the process are no longer set on the props, which improves the strength and reliability of the props, avoids accidents such as roof intrusion caused by welding interruption, and ensures the safety of workers. Each prop series of props currently used at home and abroad welds the props equipped with three-way valves to the props to reduce the strength of the props. According to the specifications of the prop, the weight of the prop is reduced by more than 5-30% compared with the existing props at home and abroad, but its working resistance, working stroke and stability safety factor are higher than those of aluminum alloy props.
