Causes of wear and tear of water ring vacuum pumps:
Due to the large diameter of the rotor impeller of the water ring vacuum pump, it is affected by factors such as water resistance and volume change when rotating, and this structural characteristic determines that the rotor blades bear a certain radial variable load during the operation of the rotor shaft, and will also bear a large axial force. Especially in the case of severe fouling of the rotor blades, the failure of the impeller dynamic balance will cause greater equipment vibration. The most commonly used double row tapered roller bearing is 35000 type, which has a double raceway outer ring and two inner rings, and there is a spacer ring between the two inner rings, and the clearance can be adjusted by changing the thickness of the spacer ring. These bearings can accommodate bidirectional axial loads while carrying radial loads, which limit the axial displacement of the shaft and housing within the axial clearance range of the bearing. The main reasons for the wear of the water ring vacuum pump shaft are the machining accuracy of the rotor shaft, the lubrication of the bearing, the quality of the parts, the fatigue wear of the normal metal, the quality of the bearing, and the fatigue characteristics of the metal.
How to use Soray carbon nanopolymer material technology to repair the wear of the water ring vacuum pump shaft?
1.The surface is treated with oil, and all the oil stains on the bearing position are dried with oxygen acetylene until carbonized.
2.Surface grinding treatment, use a grinding machine to polish the surface roughness to determine that there is no high point on the surface.
3.Surface cleaning, clean and polish the worn surface with anhydrous ethanol, and thoroughly clean it to ensure that the surface is free of debris.
4.Blend the material, blend the carbon nanopolymer material well, and blend evenly without color difference.
5.Apply the carbon nanopolymer material, evenly apply the material to the repaired surface, and scrape it repeatedly.
6.Wipe the inner surface of the tooling with alcohol, apply the release agent, and then assemble the tooling.
7.The shaft head is heated to improve the material properties, and the tooling is disassembled after the material is cured.
8.After the measurement size is confirmed, remove the excess material to ensure that there is no excess material in the rear axle shoulder, and reinstall the bearing.
