The harm of sand making machine oil pipe blockage

We know that the sand making machine needs to be lubricated when it is in use. The lubrication is generally done in the lubrication system. Generally, after the lubricating oil is added, the lubricating system automatically completes the lubrication operation, but sometimes, due to some The reason is that it will cause the blockage of the tubing. At this time, how will it affect the production of the equipment?
 
Case 1: If the oil pipe of the sand making machine's lubrication system is blocked, the lubrication system cannot play a lubricating effect, which will cause the oil pressure to rise and the oil temperature to rise;
 
Case 2: If the oil return pipe of the sand making machine is blocked, it will cause the lubricating oil to leak from the water seal dust-proof device, resulting in oil in the water seal drainage, but the oil pressure has not increased;
 
Case 3: When the oil return groove on the spherical bearing seat or the spherical bearing is blocked, it will cause the lubricating oil to leak from the dustproof device of the water seal, resulting in oil in the water seal drainage and abnormal oil pressure;
 
 
 
 
From the above analysis, it can be seen that the blockage of the oil pipe of the sand making machine may cause the increase of oil pressure and oil temperature, but the change of oil pressure and oil temperature does not mean that it must be caused by the blockage of the oil pipe, or it may be Caused by the following reasons:
 
1. When the thrust disc of the sand making machine fails, the oil temperature will exceed 60℃, but the oil pressure will not rise;
 
2. When the eccentric bushing of the sand making machine and its inner and outer bushes fail, the oil temperature will exceed 60℃, but the oil pressure will not rise;
 
3. When the spherical bearing of the sand making machine fails, the oil pressure will not rise when the oil temperature exceeds 60℃;
 
The article analyzes the hazards of the oil pipe blockage of the sand making machine, mainly due to the abnormality of the oil temperature or oil pressure, but when the oil temperature or oil pressure is abnormal, it does not mean that it must be caused by the blockage of the oil pipe, or other aspects. In the use of the sand making machine, no matter what causes the abnormal oil temperature or oil pressure, it needs to be dealt with in time to prevent the production harm.
