In order to make the hydraulic acrow props work stable, give full play to the efficiency of the equipment, and extend the service life, in addition to strictly complying with the operating procedures, it is necessary to strengthen daily maintenance.
1. The single hydraulic prop should be disassembled and connected before work, and the roof should be paid attention to, and the protection work and personal equipment should be done well. Replace the hydraulic components such as the pillar, front beam jack, control valve, etc., first use the single hyadraulic prop to suspension hydraulic prop the top beam before proceeding. Each of the pillar brackets, the control valve and the piping system in the jacks reached, in the case of tension, When repair and replacement are not possible, they must be performed after unloading.
2. In the process of disassembly and maintenance of the suspension hydraulic prop, suitable tools must be used to prevent bumps, especially the smooth surface of each cylinder piston, the valve shaft and sealing surface of each valve part, pipe joints and connecting threads, etc. Prevent damage to avoid increasing the difficulty of maintenance,
3. Assemble and disassemble parts, and mark the mark in the required size and quantity, and put it in place. The removed small parts, such as cotter pins, gaskets, and sealing rings, should be placed in the tool bag to prevent loss.
4. Every cylinder, valve and other hydraulic components on the bracket are usually not allowed to be debugged and disassembled. If no problems are found, they can be used. One group must be replaced for maintenance and sent. In the process of dismantling and single hydraulic prop moving, each cylinder should first shrink to a shorter length to facilitate handling and prevent the surface of the piston rod from being damaged and corroded.
5. Every hose from the liquid inlet, pillars, and valve components of various A replacement sockets must be protected with suitable plugs, and should be stored and handled, and the plugs should not be screwed out to avoid dust and dirt materials. Into the cavity, the influence of the hydraulic acrow props hydraulic working system.
