The sealing compensation and sealing tensioning technologies are selected for each sealing gasket of the single hydraulic prop, which reduces the replacement rate of the sealing parts, and the assembly, disassembly and repair are simple. The working characteristic of the single hydraulic prop is a constant-bottom curve, its initial differential force depends on the pump pressure, and the working resistance is adjusted by the safety valve. Zhifuyi has two working price ranges: the increase map and the quilt.
In the stage of increasing resistance, the working resistance of the single hydraulic prop is affected by the pressure of the roof rises gradually to reach the fixed working resistance position. The feature of this stage is that the safety profile does not open, and your star under the roof is small. The constant map phase is to open safely when the bearing load exceeds the city's fixed work resistance, the hydraulic acrow props overflow, the support pressure is lower, and the work resistance With a slight drop, the safety gate is closed, and the page board reaches the balance of the heart.
This over and over again, the Baoya hydraulic acrow props works under the rated working resistance, and shrinks as the roof sinks, and it is not broken. Therefore, its persistence is better than the big support and the reduction support. The wave pressure is very thick, and the qualitative performance is relatively good. It can be used with the metal dumpling roof beam to support the roof of the high-end general mining and the blasting face and the support end of the fully mechanized mining face, or it can be used separately It can be used as a point hydraulic prop or other temporary support.
In summary, the single hydraulic prop has the characteristics of large stroke, convenient operation and maintenance, and good stability. All of them can be widely used in mine safety protection and become a popular hydraulic prop product.
