When the FRP single hydraulic prop is lifted, the liquid injection gun in the pipeline system is inserted into the three-way valve oil filling valve body.
Double telescopic suspension monomer hydraulic prop is a new-generation working surface single-supporting product, which is an auxiliary equipment for high-grade mechanized general mining working face
According to the working principle and structural characteristics of the single hydraulic prop, the following conditions are analyzed for the conditions for forming the expansion cylinder:
In general, the cylinder can be deformed or even damaged only if the cylinder is pressed and reaches or exceeds the strength limit of the cylinder.
The safety valve in the three-way valve is a key component that keeps the strut in a constant-resistance operating characteristic.
Strengthen and improve the water quality supervision and management of working medium in hydraulic system of working face.
