Analysis of magnetic pump common problems
Magnetic pump common problems:
1. Magnetic pump due to cavitation problems: pump cavitation caused mainly by the pump inlet tube resistance, medium more gas transmission, filling pump is not sufficient, the pump inlet can not enough and other reasons. Cavitation is the most damaging to the pump. The pump vibrates violently when cavitation occurs. The serious balance will destroy the pump bearing, rotor or impeller. This is a common cause of magnetic pump failure.
2. No medium or medium flow rate is small: the rotor shaft and the stability of the dry friction bearings, burning bearings. Magnetic pump is provided by the transmission medium to the sliding bearing lubrication and cooling, without opening the valve or outlet valve in the case of sliding bearing lubrication and cooling without the transmission medium caused by high temperature and thus damaged.
3. Isolation sleeve damage: Magnetic pump magnetic coupling pump is transported by the media cooling, if the media with hard particles, it is easy to cause the isolation sleeve scratched or scratched, and sometimes if improper maintenance may also cause the isolation sleeve damage.
CNC laser cutting technology is computer numerical control (CNC) equipment capable of cutting holes and intricate shapes with outstanding precision. Laser cutting is a technology designed to produce metal parts from sheet metal through the use of a focused, high-powered laser beam, which vaporizes, melts, burns, or removes material by essentially blowing it away by a jet of gas. This process results in an edge with a high-quality surface finish. This technology, which was initially used for drilling holes into diamond dies, emerged in 1965 and has since been adapted for industrial use and has evolved to be capable of cutting various materials. Laser metal cutting machines cut materials including titanium, aluminum, steel, stainless steel, spring steel, brass, copper, and bronze.
Surface Finishing: Powder Coating, painting, plating, anodizing, polishing, Sandblasting spray coating

Laser cutting process is commonly used in sheet metal manufacture, we have many parts that have been cut which are used on the juice machines. Different level thickness sheet metal can be made by different power laser cutting machine. Rapid prototype samples can be made and also the lower cost benefits for the big volume.
