The DW single hydraulic prop is a constant resistance prop, which can be matched with various top beams and can also be used as the main post. It can be used for the support of general mechanized coal mining or blasting face in coal mines, as well as the end support or other temporary support of comprehensive mechanized coal mining face.
DW single hydraulic prop is suitable for roof support at coal mining face, end roof support at fully mechanized mining face, and advanced support for roadway tunneling. Suspension type single hydraulic prop is a type of external injection type single hydraulic prop, but it has a significant advantage over external injection type single hydraulic prop. That is that DWX type single hydraulic prop adopts the principle of plunger suspension technology, suspension The force reaches four-fifths of the working resistance, and the force of the column is only one-fifth. The DWX-type three-way valve is installed on the handle body. When filling the liquid, the three-way valve does not rise with the rising of the living column , Easy to operate and reliable.
The inner wall of the upper section passes through a dust ring and a y-shaped sealing ring. Fluoroelastomer type 0 ring is also a kind of sealing ring. When DW single hydraulic prop is used on other products, it has certain air tightness and flame retardancy, which can make many products have better sealing effect. Like mechanical equipment such as pumps, its hydraulic oil tank needs to use better performance fluoroelastomer 0 ring, because it needs good tightness, so there is nothing wrong with choosing it. When in use, the fluoroelastomer O-ring can be used in an environment of up to two hundred and fifty degrees Celsius, and it will not be deformed, and can maintain its own sealing performance. Fluoroelastomer 0 ring with different specifications can also be customized according to different needs to meet different sealing needs.
