It is often used.
1. diving mixer prolonged application is in wastewater media, sanitary sewage and industrial wastewater complicated component, containing a large amount of
Suspended matter and various density the grains of sand and the solid particles such as mud.Even across the processing of preceding road technique, still some
The grains of sand and mud enter in subsequent technique.In operation, these solid particles can be deposited on where mechanical seal diving apparatus
Cavity in, on the one hand these solid particles can destroy the sealing surface of mechanical seal, so that liquid is entered motor cavity, on the other hand make
The heat dissipation of sealing surface is difficult, causes diving mixer that cannot work until damage.
2. due to being constantly present certain gap between impeller and mechanical sealing base, the particle in sewage is inevitably wanted
Some is entered in the cavity where mechanical seal, influences the safe handling of mechanical seal.
Invention content
The present invention provides using efficient permanent magnet motor and the efficient permanent magnet diving mixer containing pre-washing function, tool
In cavity where having energy-saving and solid particle that cannot be deposited on mechanical seal, it is ensured that the work(of mechanical seal safe operation
Effect.
