The suspension hydraulic prop is often used as support equipment in coal mine, which is a dangerous place underground.Suspension hydraulic prop is a type of external injection monomer hydraulic prop, in the injection of liquid, three valves do not rise with the prop of the living column, easy to operate, safe and reliable. Large working trip, expanding the scope of use, especially the roof sinking larger working face. Do you really understand the process of pillar work, the following small make up of the lens to analyze it.
Working process of suspension hydraulic prop:
The working principle of suspension hydraulic prop includes four steps: lifting column, initial support, load bearing and return column, namely:
The process of lifting and initial support of suspension hydraulic single prop
When lifting the column, insert the injection gun in the pipeline system into the three-way valve filling body, hang the lock sleeve and operate the injection gun. The high-pressure liquid in the pump station opens the spherical one-way valve in the three-way valve through the nozzle and enters the column, forcing the moving column to rise.
Suspension single hydraulic prop support process
The prop recovery, insert the uninstall hand three valve barrel discharge hole, uninstall hand, forcing valve sleeve, connecting screw, fill the body, such as the overall axial movement, compression unloading valve spring, left left unloading valve, the valve sealing surface barrel unloading valve is opened, liquid column inner chamber work, the left cylinder valve into the mined-out area, the next column life in self-esteem and reset spring. Full prop of economic recovery.
There are many links in the working process of the suspension hydraulic prop. Only in these links can we get higher efficiency and better benefits.
