Single hydraulic prop

Single hydraulic prop ：

Single hydraulic prop for seam angle is lessthan 25 degrees - 35 degrees inclined coal seam mining face, the adaptation ofthe coal seam roof and floor conditions are: roof pillars behind do not affectthe recovery of base should not be too soft, prop depth is not pressed into thefloor deterioration of the integrity of the base plate, or should increase thebase. In the coal mining face relatively loose cannon when used on the livecylinder coating surface to take protective measures to prevent collapse. Withwooden roof beams and pillars or columns used to do, you should replace thecolumn caps cover to prevent damage to wooden beams.

Advantages：

1 Small size

2 Support high

3 Support reliable

4 Convenient to use and repair

5 Integrated low cost

Troubleshooting and Maintenance：

Local scratches and hydraulic equipmenthydraulic prop deformation is common problem, especially in the mouthdeformation piston leakage, corrosion and other problems downhole hydraulicprop, due to equipment disassembly more difficult problems mentioned above andmore traditional methods to solve difficult scene to replaced with new partsbased, but the replacement cycle is long and expensive. Hydraulic prop for thelatest contemporary repair methods to polymer composites based. Which hasexcellent adhesion and good compressive strength, not only to meet therequirements of the conditions of the production and operation process issimple, neither heat affected, coating thickness and unrestricted. While thecoating itself has excellent corrosion resistance and oil self-lubricatingfunction to ensure the wear resistance after the repair, to ensure normalproduction, to avoid damage to equipment components increased.
