Oxidation ditch wear-resistant submersible thruster

Oxidation ditch wear-resistant submersible thrusterFeatures and advantages:

1. The blades have self-cleaning function, which can prevent debris from entangling and blocking.

2. Compact structure, small volume, and light weight. Easy operation and maintenance, convenient and fast installation, and long service life.

3. When used in conjunction with an aeration system, energy consumption can be significantly reduced, oxygen filling can be significantly increased, and sedimentation can be effectively prevented.

4. The motor winding is insulated to Class F with a protection level of IP68. It uses imported bearings with one-time lubrication and maintenance free function, which have oil chamber leakage detection and motor winding overheating protection functions, making the operation of the motor safer and more reliable.

5. The friction material of the mechanical seal is corrosion-resistant tungsten carbide, and all fasteners are made of stainless steel material.

Oxidation ditch wear-resistant submersible thrusterPrecautions for using submersible thrusters:

1. The temperature of the medium shall not exceed 40 ℃;
2. The pH value of the medium is between 5-9;
3. The liquid density shall not exceed 1.15 kilograms per cubic meter;
4. Long term diving operation, with a diving depth generally not exceeding 20m.

Submersible impeller, also known as low-speed impeller or impeller mixer, is a low-speed, large blade sewage mixing equipment commonly used in hydraulic circulation. It mainly consists of submersible motors, reduction devices, propellers, installation systems, etc., usually installed underwater using guide rods. The development of submersible thrusters is based on the production technology of submersible mixers, so their production process and performance characteristics have many similarities with submersible mixers. The main difference is that the speed of submersible thrusters is generally lower, usually between 36-115r/min, and the impeller diameter is larger, usually between 1100-2500mm.

The flow field distribution of a submersible thruster is relatively uniform, with low and slow flow velocity, but a wide range of action. This type of product is suitable for treatment structures that do not require a GT value (concrete mixing strength value) and have a large tank space, with the purpose of hydraulic circulation and maintaining flow velocity. This type of equipment is widely used in industrial and urban sewage treatment plants for anaerobic tank agitation and oxidation ditch push flow, generating low-speed tangential flow and creating water flow conditions for denitrification and phosphorus removal processes.
