The hydraulic support column is one of the key components of the supporting facilities under the mine. Do you know the working principle of the hydraulic support column? Let's take a look at how a hydraulic support column works.
The process of lifting column and initial support of hydraulic support column:
When lifting the column, insert the nozzle in the pipeline system into the injection hole of the three-way valve, hang the lock sleeve, operate the nozzle, push the high pressure of the pump station through the nozzle, and then open the spherical one-way valve in the three-way valve, and enter the column to make the live column rise.
The process of bearing and overflow of hydraulic support column:
Live column after lifting in hosted mode, because of increased support when long, the role of the roof on the hydraulic support column load increases, when the column of load is beyond rated running resistance, the column inner chamber of the effect of high pressure liquid mat in the relief valve, beyond the safety valve spring setting in advance to hexagon guide sleeve clamp force, compression safety valve spring, valve pad and hexagonal guide sleeve, the relief valve pad out of the seat, the valve is opened, the inner cavity spill, falling. Rebalanced roof pressure.
The process of hydraulic support column return:
Column when withdrawing, unload the handle will be inserted three right valve valve barrel discharge hole, rotational unloading handle, prompting valve sleeve, connecting screw, liquid injection valve body, such as the axial movement, compression unloading valve spring, unloading valve pad out left sealing face of valve barrel, unloading valve is opened, the left column inner chamber working liquid valve barrel spillover, live column in its own weight and the role of the return spring next time, achieve pillar.
