Suspended single hydraulic prop is a new generation of single support product for working face, it is the supporting equipment for high-end mechanized general mining face, and also the leading support equipment for fully mechanized mining face. It is suitable for roof support of coal mining face. Support, the end roof support of fully mechanized mining face, and the advanced support of roadway excavation. Because of its large bearing capacity, strong anti-eccentric load capacity, large working stroke, and wide range of use, it can be applied to thin coal seams and medium-thickness Coal seam and thick coal seam working face.
Suspension single hydraulic prop Purpose: Protect the rock falling from the roof and roof of the working surface, and ensure a safe working space.
Suspension hydraulic prop Principle: The single hydraulic prop is injected into the three-purpose valve connected with the single hydraulic prop through the hydraulic station, the single hydraulic prop starts to rise and reaches the required height, and the sealing effect in the hydraulic prop is used to complete the support. If it falls, open the three-way valve to unload, and the hydraulic prop will begin to fall to complete the work.
Single Hydraulic Prop Features: Convenient transportation, convenient working surface, convenient movement, convenient maintenance, time-saving, labor-saving, money-saving and worry-free.
1. Large supporting force, anti-eccentric load
Adopting the principle of plunger floating technology, the buoyancy of the pillar is four-fifths of the working resistance, and the force of the pillar is one-fifth, which greatly improves the stability and safety of the hydraulic prop, and improves the bearing capacity of the support height of the pillar. Carrying capacity.
2. No weld
The column is not equipped with arc welding, which is difficult to guarantee by the process, which improves the strength and reliability of the column, avoids the danger of accidents such as conflicts caused by the interruption of welding, and ensures the safety of the producer.
3. Lightweight
According to the specifications of the suspension hydraulic prop, the weight of the pillar of the same specification as the DZ type is reduced by 15-20%, and its weight is the same as that of the aluminum alloy pillar, but the working resistance and working stroke are much higher than that of the ancestor alloy pillar, and it is convenient to move, transport and use.
4. Large stroke
The suspension type single hydraulic prop has a large working stroke and an expanded range of use. One specification can replace the specifications of the other prop Z-5. The specification is reduced, the pillar reserve is reduced, the use efficiency is improved, and the cost is reduced.
5. No internal leakage, safer
The pillar has no internal leakage, and the leakage of the pillar can be visually inspected. Once the leakage is found, it can be replaced in time, which avoids the false top of the pillar and the tedious inspection work caused by the leakage in the hydraulic prop, and it is safer to use.
