Water ring vacuum pump bearing bit failure how to deal with it?
　　
Six water ring vacuum pump considerations:
　　
①The medium to be conveyed and its temperature should be within the allowable range of the pump. Engineering plastics pump temperature <60 ℃, metal pump temperature <100 ℃, conveying suction pressure is not more than 0.2MPa, the maximum working pressure 1.6MPa, the density of not more than 1600Kg / m3, the viscosity is not more than 30X10-6m2 / S Liquids containing hard particles and fibers.
　　
â‘¡ be transported medium, if it contains solid particles, pump inlet to be added to the filter: If containing ferromagnetic particles, the need to add magnetic filters.
　　
③ water ring vacuum pump in use should be less than 40 ℃ ambient temperature, motor temperature rise must not exceed 75 ℃.
　　
â‘£ 1000 hours after the normal operation of the magnetic pump should be dismantled bearings and face ring wear and tear, and replace the consumable parts should not be reused
　　
⑤ for the transmission fluid is easy to precipitate crystallization of the media, after use should be promptly cleaned, drain the pump effusion.
　　
â‘¥ Due to the cooling and lubrication of magnetic pump bearings are transported by the media, it is absolutely forbidden air-to-run, while avoiding the power outage after the restart caused by the time-space-load operation.
　　
The traditional method of repairing welding machine is easy to damage the material and lead to the deformation or fracture of the part, which has great limitation. The methods of brush plating and painting and reprocessing usually require extra-long process, not only long repairing period, high cost, Of the material or metal material, can not fundamentally solve the cause of wear and tear.
　　
Polymer composite repair materials with super adhesion, excellent compressive strength, wear resistance and corrosion resistance and other comprehensive performance. The use of the United States Ka Wah 2211F polymer composite repair materials wear parts in the transmission area is relatively small, the case can be demolished to avoid the scene to avoid machining, and no welding heat stress thermal effects, repair thickness is not limited, while the product has Wear resistance and metal materials do not have the concessions to ensure that the repair parts of a 100% contact and cooperation to reduce equipment shock and vibration, to avoid the possibility of wear and tear, and greatly extend the life of equipment components, saving enterprises a lot of downtime Time, creating huge economic value.
　　
Second, the water ring vacuum pump bearing temperature treatment and precautions
　　
(1) high temperature lubricant failure reasons
　　
(2) bearing box water, oil emulsion, deterioration
　　
(3) bearing box with impurities
　　
(4) pump load is too large
　　
(5) multi-stage pump balance disc gap is too large
　　
Approach
　　
(1) Change the lubricating oil in the bearing cavity
　　
(2) Wash the bearing housing several times
　　
(3) reduce the load according to process indicators
　　
(4) adjust the multi-stage pump balance disc gap, reduce leakage
