one Product information
QJB diving blender There are two series of products, mixing and low-speed flow pushing.
two Purpose
The low-speed plug flow series mixer is applicable to the aeration tank and anaerobic tank of industrial and urban sewage treatment plants. It can generate low tangential flow and strong water flow, and can be used for water circulation in the tank and creating water flow during nitrification, nitrogen removal and phosphorus removal stages.
three Structure introduction and performance characteristics
1. Compact structure, small volume and light weight. Simple operation and maintenance, convenient installation, and long service life.
2. The blade has self-cleaning function, which can prevent sundries from winding and blocking.
3. In combination with the aeration system, the energy consumption can be greatly reduced, the oxygen charging capacity can be significantly increased, and sedimentation can be effectively prevented.
4. electric machinery The winding is of Class F insulation and the protection class is IP68. The primary lubrication maintenance free imported bearing is selected, which has the functions of oil chamber leakage detection and motor winding overheating protection, making the motor work more safe and reliable.
5. The friction pair of mechanical seal is made of corrosion-resistant tungsten carbide, and all fasteners are made of stainless steel.
