Next, we will start to explain the knowledge points related to the internal injection type single hydraulic prop. My friends want to know more about the internal injection type single hydraulic prop as much as I do. I hope we can gain some from the following articles.
Protection Measures for Internal Injection Monomer Hydraulic Prop
1. When the hydraulic prop is not supported, the prop cannot be placed horizontally as a push jack. Note that the support handle cannot be used as the fulcrum of the push jack, otherwise the prop will be damaged in large quantities.
2. When lifting the column, first put the liquid injection gun tube on the three-way valve liquid injection valve, hang the locking sleeve of the injection gun mouth, and then operate the liquid injection gun handle. The high-pressure emulsion is supplied to the inner chamber of the pillar through the injection gun, and the movable pillar rises rapidly until the top cover of the pillar contacts the metal top beam and is close to the top plate of the working face.
3. The liquid pressure of the hydraulic pump station shall be stable to prevent the pillar unloading valve from overflowing when the injection gun is pulled out.
