DWX type (suspension type) monomer hydraulic prop is a newly developed (external injection type) monomer support equipment by the Institute of Mining Machinery of China University of Mining and Technology, and is a replacement product of DW type (piston type) monomer hydraulic prop. This pillar series has a total of 11 specifications, respectively applicable to the mining height of 0.63~2.8 meters of coal seam, the general coal seam inclination is less than 25° gently inclined back to the working face, such as taking certain safety measures, the use of the range can be extended to the inclination of 25°~45° back to the working face. DWX type (suspension type) single hydraulic prop can be used in the same working face as DW type (piston type) single hydraulic prop.
DW type monomer hydraulic prop is a kind of external liquid supply constant resistance monomer hydraulic prop with constant and unchanging working resistance, which is suitable for different roof conditions and different mine pressure requirements. It is matched with different specifications of metal hinged top beams or long beams, which can be applied to any mining face with a coal seam inclination below 35°, and the pillar can be changed into a large flow three-purpose valve to meet its support requirements.
Technical features and basic parameters:
For example, DW28-250/100X D stands for single hydraulic prop; W stands for external injection; 28 is the maximum height of the pillar (unit: dm); 250 for
Rated working resistance of the pillar (unit: kN); 100 is the cylinder diameter of the pillar (unit: mm); X is the technical principle of using the plunger suspension type.
