Water ring vacuum pump is analysed the cause of the broken shaft -

water ring vacuum pump is a commonly used equipment of the factory. When the time is longer, much bigger than the problem. The broken shaft problems usually occur. Many people don't understand why this is so, so let's introduce equipment broken shaft.

1。 Water ring vacuum pump engine shaft end clearance is too large or serious ablation, engine in the process of running back and forth motion.

2。 The main bearing has loose and wear for too long. The fracture occurred in the second part of the engine shaft. This is due to the frequent engine shaft radial runout, which leads to the engine shaft fracture.

3。 The shaft end thrust surface on the spindle. At the same time, the engine shaft also has air compressor load. When the air compressor load increase, it is easy to ablation or loosen the motor shaft and produce radial runout.

4。 If the main bearing and connecting rod bearing ablation for many times, the ablation of support is abate, shaft radial runout will frequently. In addition, the stress change after ablation in the root, so break in between shaft roots and arm.

5。 Between the adjacent main bearing clearance is too large, especially after the main bearing and the former two between two main bearing clearance is too large. Behind the engine shaft has a flywheel, the engine shaft in front of a pulley. When the engine is the heavy stress on both ends of the shaft, the radial frequently.

6, or a large amount of water ring vacuum pump shaft bending of the center, and the main bearing clearance due to uneven elasticity, prevent the rotation of the engine shaft, and uneven load before and after the engine shaft, radial runout frequently.

7。 Main bearing ablation or rolling bearing will eventually lead to the engine shaft beating back too.

during the running of water ring vacuum pump, may suddenly appear the phenomenon of shaft fracture. Shaft fracture may occur in the surface of the moment, but in fact are accumulated to a certain level of the results of the quantitative change and qualitative change. As a result, the final is the lack of maintenance and repair. We should do in well, reduce trouble.
