Analysis and solution of stone crusher heating causes

Heating during operation of stone crusher is a common equipment failure. This problem not only affects the of the equipment, but may also cause more serious mechanical failures. This article introduces three aspects: analysis of stone crusher heating causes, fault diagnosis methods and solutions.

1. Analysis of stone crusher heating causes

Poor bearing lubrication is one of the main causes of stone crusher heating. Insufficient or deteriorated grease will increase friction and generate a lot of heat. Bearing damage, such as raceway spalling and cage breakage, can also cause abnormal heating. Transmission system failures, such as overtightened belts and poor coupling alignment, will increase additional loads and cause temperature increases.

Overload operation will cause the equipment to exceed the design load and cause the overall temperature to rise. Cooling system failures, such as cooling fan damage and radiator blockage, will reduce heat dissipation efficiency. Electrical system problems, such as motor winding short circuit and loose wiring, will also cause abnormal heating.

2. Fault diagnosis method

Temperature monitoring is a more direct diagnostic method. Use an infrared thermometer to regularly detect the temperature of key parts such as bearings and motors. Vibration analysis can detect faults such as bearing damage and poor alignment. Vibration spectrum analysis can accurately locate the source of the fault.

Lubrication status inspection includes grease quantity, contamination degree and deterioration. Current detection can detect electrical system problems and overload conditions. Observe the operating status of the stone crusher equipment and pay attention to abnormal noise, vibration and other phenomena.

3. Solutions and preventive measures

For lubrication problems, a regular lubrication system should be established and the appropriate type of grease should be used. Damaged bearings should be replaced in time to ensure installation quality. Adjust the transmission system to ensure that the belt tension is moderate and the coupling is accurately aligned.

Control the feed rate to avoid overload operation of the stone crusher equipment. Maintain the cooling system, clean the radiator regularly, and check the cooling fan. Repair the electrical system, tighten the terminal blocks, and replace damaged components.

Preventive measures include: establishing a stone crusher equipment inspection system and regularly checking key parts; installing temperature monitoring devices to achieve real-time monitoring; strengthening operation training and standardizing equipment use; formulating maintenance plans and regularly replacing wearing parts.
