Correctly repairing leakage problems of bridge cranes
Bridge cranes are widely used and widely used in a wide range of applications. They are widely used in indoor and outdoor industrial and mining enterprises, railway transportation, steel and chemical industry, port terminals and logistics turnover. And once the bridge crane fails, how should it be dealt with?
For bridge cranes, the corresponding solutions for different faults are different. If it is because of frequent operation, multiple reverse emergency stops and stops, causing the crane reducer and active wheels to wear and leak. .
Then the traditional methods are mainly repaired by repair welding or brush plating, but the thermal stress generated by the repair welding high temperature can not be completely eliminated, and it is easy to bend or break; while the brush plating is limited by the thickness of the coating, it is easy to peel off, and above Both methods use metal to repair the metal, and under the combined action of each force, it will still cause re-wear.
For the problem of effectively solving the bridge crane, it is mainly based on the repair of polymer composite materials. This material has excellent adhesion, excellent compressive strength and other comprehensive properties, and has no effect of repair welding thermal stress, repair thickness. It is also unrestricted, and the metal material of the product does not have the concession, which can absorb the shock and vibration of the equipment, avoid the possibility of re-wearing, and greatly extend the service life of the equipment components.
If the bridge crane trolley reducer is affected by vibration, wear, pressure, temperature and other factors, the static sealing part of each joint surface often has oil leakage phenomenon, and the polymer composite material is used to treat leakage on site, which can be disassembled, and The material has excellent adhesion, oil resistance and 350% stretch, which is good for overcoming the effects of the vibration of the reducer.
