How to carry out maintenance on the trolley line

Safety slide lines should be checked regularly during normal operation, because the use of electricity equipment is a major error in each industrial and mining company's main production tool, which will directly affect the factory's production efficiency. When checking the trolley wire, check whether there is any looseness and disengagement at every 6m. When checking the conductive device, check whether the movable part is flexible, whether the tension spring is fatigued, the brush is worn, etc. (These conditions will affect To track the conductive properties and the tracking performance of the conductor should be adjusted in time).

During the renovation of holiday equipment, the conductive device is pulled out of the catheter and the brush roller of the conductive device is inspected for wear. If the brush extension is less than the specified effective length, it must be promptly replaced. When the guide roller is deformed seriously, it must be replaced to maintain the conductive device. Run normally and brush well and check the cause. Safe slide wire In all parts, the brush is the only part that will normally wear out.

For severely corrosive gas environments, the corrosion of brackets, hangers, and retractors must be checked and measures must be taken to apply anti-rust materials.

Use the place where the trolley wire is used, such as when performing infrastructure. Do not; hit, hit the pressure transmission conduit, but are not allowed to press the weight on the transmission conduit. Prevent deformation and cracking of power transmission conduits, affect their use, and cause safety accidents. After the infrastructure is completed, the infrastructure waste on the power transmission conduit should be immediately removed.

During normal maintenance, the staff is not allowed to step on the power transmission conduit or its support to prevent damage to the flatness of the entire line and accidents.

This kind of parts are for Jcb engine , it includes Cylinder block, cylinder gasket, cylinder head, crankcase, cylinder liner and oil pan, piston, piston ring, piston pin, connecting rod, crankshaft, flywheel, torsion damper, balance shaft etc. Valve set includes valve, valve guide, valve seat and valve spring, etc. Valve transmission group mainly includes camshaft, timing gear, tappet and its guide rod, push rod, rocker arm and rocker arm shaft, etc. Its function is to make the intake and exhaust valves open and close at the time specified by the valve distribution phase, and ensure sufficient opening.
