How to solve the heating of the double beam bridge crane motor

Double girder bridge crane maintenance refers to the technical work carried out to restore the function of the equipment after the equipment technical condition deteriorates or breaks down. This approach is relatively passive. I don't know when the double girder overhead crane breaks down. The disadvantages of passive maintenance are obvious, such as interruption of production plan, maintenance time and uncertainty of cost. It is often encountered that the maintenance cost of the crane exceeds the limit approved by the leader, which causes the maintenance time to be extended. In fact, maintenance is a relatively primitive equipment management system, which is only suitable for some small equipment.

The maintenance of the double-beam bridge crane is mainly to disassemble, inspect and adjust its main components. It is a planning method of equipment management that allows replacement of parts that have reached the specified wear limit when necessary. Ordinary production units should conduct regular or irregular inspections and repairs based on the usage of the equipment. The difference between overhaul and overhaul is that when the production task is not tight, a certain overhaul time can be actively arranged. Double-beam bridge cranes are special equipment. The repair project is organized and implemented by a professional construction unit.

The double-beam bridge machine inspection is a scientific management method, which can grasp the equipment operation status in time and guide the maintenance work. Check and monitor equipment, discover equipment aging and hidden danger information, analyze the causes, take measures to improve, treat equipment maintenance as preventive maintenance, and eliminate hidden dangers in equipment management methods. The lifting equipment is mainly inspected by the user, and the hidden danger record is found as the key report for the next maintenance.

In the management of double-beam bridge cranes, the manufacturer recommends that users "check, repair, and repair less." That is, daily operators should conduct spot checks on lifting equipment. For crane maintenance units, it is necessary to pay attention to maintenance work to eliminate faults. Reduce the number of passive maintenance and ensure safe production.

The heating of the motor of the double girder bridge crane is because the bearing does not have lubricating oil, which will cause the motor to heat up. Bearings lacking lubricating oil can cause noise and vibration, which can cause the motor to heat up. This will also cause the rotating shaft to bend. Incorrect positions of the frame, rotor and end cover will cause the cavity to be cleaned, which can easily cause the motor to heat up or even burn. When it is found that the bearing is short of oil, lubricating oil should be added immediately to make the bearing run smoothly.

The heating of the motor of the double-girder bridge crane is because the high voltage of the power supply will also cause the motor to heat up and generate hum. Long-term high voltage will burn out the coil, so the power supply of the electric hoist should be equipped with a transformer and continuous protection.

The double-beam bridge crane motor generates heat because dust and debris from the motor will reduce the insulation performance of the motor. When there is debris in the air gap between the stator and the rotor, the motor will sweep through the air chamber, causing wear of the motor winding insulation. In severe cases, the engine may even be scrapped. It is recommended to clean the motor frequently.

The heating of the motor of the double girder bridge crane is because the motor is overloaded and it will also cause the motor to heat up. Under intense production tasks, the electric hoist crane runs 24 hours a day. Continuous operation is very harmful to the motor. Not only will it cause the motor to heat up, it will also affect the service life of the motor. Therefore, no matter what kind of mechanical equipment cannot be overloaded for a long time, the necessary rest must be given.
