2 - bv6 water ring vacuum pump shaft fracture reasons

the liquid chemical pump discharge in many manufacturing and regular, so using a variety of pumping machinery and equipment is very important. Water ring vacuum pump is not only simple in structure, convenient maintenance, and is suitable for pumping liquids and flammable and explosive substance steam or dust, vapor, etc. Therefore, it is warmly welcomed by many manufacturing. Underneath, small make up 2 bv6 water ring vacuum water pump manufacturer will show you the cause of shaft fracture.

1。 2 bv6 water ring vacuum pump diesel engine bearing end cover clearance is too large or corrosion is serious, causes in the operation of the sloshing around.

2。 If there is a crevice corrosion on the sidelines of the rolling bearing and rolling bearing, the vibration of the diesel engine shaft back will be more and more big.

3。 Mechanical equipment of main rolling bearing damage is too big, lead to a loss for a long time, the lower cracking diesel engine shaft. This is usually due to the condition of diesel engine shaft axial vibration too often is caused by the diesel engine shaft fracture.

4。 When water ring vacuum pumps and pump shaft bending too much different, and the main roller bearing clearance flow closely and not loose evenly, diesel engine shaft was blocked in the process of spinning, so if the diesel engine shaft before and after, left, right non-uniform load, its axial vibration occur very frequently.

5。 Crankshaft rolling bearing in the main rolling bearing and the multiple crack corrosion, can make the support plate force, the gap corrosion so shaft axial vibration is very frequent, if the root crack appeared in situ stress changes after corrosion, the axis of a root and arm to produce fracture in the middle.

6。 If the gap between the adjacent main rolling bearing is too big, after the two main rolling bearing and the first two main gaps between rolling bearing can be very big. If the clearance is too large, the diesel engine shaft behind have a flywheel, diesel engine shaft in front of a pulley. Diesel engine shaft on both sides of the pressure is too big, can also lead to frequent axial vibration.

7。 Diesel engine shaft of mechanical equipment, there are air compressor load. When the air compressor load expands, diesel engine shaft will be corrosion or loose, causing the axial vibration.

8。 Water ring vacuum pump support plate force of rolling bearing and spindle bearing alignment change is very big, will focus on the arm of the in situ stress. In addition, the arm is weaker than the motor shaft, motor shaft fracture easily.

that's small make up 2 bv6 told us the failure reasons of water ring vacuum pump shaft. On the surface, the common failures usually occur in an instant, but in fact, they are accumulated to a certain degree and quantity change lead to the deterioration of the results. Therefore, in normal applications, based on the supporting shaft fracture of appropriate prevention and maintenance are still some save opportunities, I hope you can be familiar with.
