　　1. The sand making machine has abnormal vibration.

　　Causes of the problem: 1. Excessive wear of the transmission bearing; 2. In or serious damage to the gear meshing; 3. Looseness of the anchor connecting bolts or the large gear connecting bolts, etc.

　　Corresponding solutions: 1. Replace the worn bearings; 2. Adjust the gear clearance or replace the gear parts; 3. Re-tighten the loose pedal bolts.

　　2. The sand making machine produces a strong impact sound

　　Cause of the problem: When the sand making machine is working norm y, if foreign objects are mixed between the gears or the gears are loose and hit the teeth, the equipment will produce a strong impact sound. When the rotating bearing on the foundation or the connecting rod bolt is loose, the impact sound can also be produced.

　　Solution: In this case, it is necessary to s* for inspection, remove foreign objects, replace worn gears, and tighten connecting rod bolts.

　　3. The main bearing is overheated, resulting in abnormal conditions

　　The main bearing is an important part of the sand making machine. It should be inst ed in strict accordance with the operating specifications. No impurities should enter the bearing. The amount of sand should not be too much or too little. The main bearing should be lubricated and cleaned regularly to avoid overheating or When the power is cut off, the main bearing bears heavy load when it works for a long time.

　　4. The temperature of the upper and lower bearings of the sand making machine will be too high

　　When the instrument of the sand making machine shows that the bearing temperature exceeds the standard, it should be s*ped for inspection.

　　Reasons: 1. The motor is overloaded for a long time; 2. The main bearing is damaged (the operator be familiar with the sound when the bearing is running. If the sound changes, especi y if the sound is lower than usual, it means that the bearing has aged; 3. The bearing grease is insufficient; 4. A clogged grease groove causes the pressure in the bearing housing to rise, causing the grease to fail.

　　Solution: 1. Appropriately reduce the motor load; 2. Replace the damaged bearing; 3. Add grease; 4. Clean the grease groove.
