As we all know, the single hydraulic prop is a new environmentally friendly support equipment. It can be used with metal hinged roof beams for general mining and artillery. It uses working face to support the roof and fully mechanized mining face. Used as a props or other temporary support. Let's take a look at the working characteristics of the single hydraulic prop when working together!
The seals of the single hydraulic props use seal compensation and seal tightening technology, which reduces the replacement rate of the seals, and the assembly, disassembly and repair are simple. The working characteristic of the single hydraulic prop is a constant resistance curve. Its initial supporting force depends on the pump pressure, and the working resistance is set by the safety valve. The prop has two working stages: increased resistance and constant resistance. The resistance increase stage is that the working resistance gradually rises from the prop to the rated working resistance position under the influence of the top plate pressure. The characteristic of this stage is that the safety valve does not open and the amount of sinking of the top plate is very small. In the constant resistance stage, when the prop supports exceed the rated working resistance, the safety valve opens, the liquid in the prop overflows, the pillar contracts, the working resistance decreases slightly, the safety valve closes, and the top plate reaches the balance of the heart. This process is repeated from time to time to ensure that the working resistance within the prop is maintained under the rated working resistance, and it will not shrink as the top plate sinks. Therefore, its characteristics are superior to wooden props and friction props. The hydraulic flow is very large, and the stability is relatively good. It can be used with the metal hinged roof beam for general mining and artillery. The working face supports the roof and the fully mechanized mining face. It can also be used as a column or other. For temporary support.
In summary, the single hydraulic prop has the characteristics of large stroke, easy operation and maintenance, and good stability. All the talents can be widely used in mine safety protection and become a popular product for everyone. Our company produces and supplies props for coal mines and related accessories.
