As we all know, the single hydraulic prop is a new environmentally friendly support equipment, which can be used with metal hinged roof beams for general mining and artillery using working face support roofs and fully mechanized working face support ends, or it can be used alone used for point support or other temporary support. The single hydraulic pillar needs to be cleaned after use, so it will be disassembled if it is cleaned. So how to disassemble correctly is very important. Let ’s understand how to replace damaged parts and replace all seals and plastic parts.
Single hydraulic prop disassembly process:
1. First, clean the surface slime and coal dust.
2. Clamp the pillar on the workbench or vise, punch out three elastic cylindrical pins with a punch, remove the top cover, unscrew the vent valve with a wrench, and release the hydraulic oil in the pillar cavity.
3. Use pliers to pull out the connecting wire in the handle body and withdraw the handle body from the cylinder body; open the unloading valve and pull out the live cylinder from the oil cylinder.
4. Remove the screw with a wrench when removing the live cylinder, remove the spring washer and steel ball, install the crank on the crank, and shake the piston to remove the piston to remove the handle.
5. Disassembly of the vent valve: Remove the end cover, take out the steel ball, use a flat-blade screwdriver to unscrew the plug, remove the spring, the valve core and the ejector rod, and remove the ejector rod from the valve cartridge.
6. Disassembly of the piston: Pull out the filter screen and guide ring by hand, and use a screwdriver to remove the y-shaped ring and the leather bowl relief ring. Use a flat-blade screwdriver to unscrew the screw sleeve and take out the check valve spring and steel ball. Use a copper or bamboo stick to lightly tap the steel ball, and the one-way valve seat withdraws together with the supporting spring and the steel ball. The special tool expansion cone is installed in the pump sleeve, and the cone sleeve is twisted with a wrench to increase the outer diameter of the expansion ring and press it tightly on the pump sleeve. The impact of the rising cone caused the pump sleeve to cut the 32 × 3.5 seal ring in the piston, and the rising cone was pulled out of the piston together with the pump sleeve. Use a wrench to turn the cone sleeve in the opposite direction to make the rising cone exit from the pump sleeve.
7. Use the retaining ring pliers for the hole to remove the unloading device, the retaining ring for the hole, and the hole plug. Use pliers to remove the cotter pin on the unloading device. Withdraw the square pin, cam and unloading ring, clamp the large flat-blade screwdriver in the groove of the safety valve and valve sleeve, cover the socket wrench on the unloading valve seat, unscrew the unloading valve seat, and carefully exit the safety with a steel rod valve.
8. Removal of the safety valve: Clamp the safety valve on a vise, use a pressure screwdriver to remove the pressure adjustment screw, use tweezers to remove the safety valve spring and hexagonal guide sleeve, and remove the valve needle. Remove the connecting screw with a wrench from the other end, install an old guide sleeve on the valve seat, and exit the valve seat with an iron rod (with a tapered hole in the center).
The above is the disassembly process of the single hydraulic prop. The correct disassembly method is a protection for the equipment. Engineers of Shandong China Group hope that everyone has a certain understanding of the removal of the single hydraulic prop.
