Low-speed thruster for oxidation tank

Low-speed thruster for oxidation tankfeature

1. Submersible thrusters have a compact structure, small size, and light weight. The characteristics of simple operation and maintenance, convenient and fast installation, and long service life.

2. The blades have self-cleaning function, which can prevent the entanglement and blockage of debris.

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.

Low-speed thruster for oxidation tankThe selection of submersible thrusters is a complex task, and the correctness of the selection scheme directly affects the normal use of the equipment. As a principle of selection, it is necessary to ensure that the thrusters can fully exert their mixing function within the appropriate capacity of the platform. This standard can generally be determined by the flow rate. According to the different process requirements of sewage treatment plants, the flow rate of the mixer selection should be ensured to be between 0.15-0.3m/s. If the flow rate is lower than 0.15m/s, the effect of thrust mixing cannot be achieved. If the flow rate exceeds 0.3m/s, it will affect the process results and cause waste.

So before selecting, it is necessary to determine where the submersible thruster will be used, such as sewage tanks, sludge tanks, or biochemical tanks; Secondly, the reference of the medium, such as suspended solids content, temperature, pH value, etc., as well as the shape, depth, and even installation method of the water tank, will have an impact on the selection. At the same time, energy-saving factors should also be considered, as this will affect the user's future operating costs. In order to achieve mixing function in different environments, we provide users with multiple models of submersible thrusters and offer selection services.

In the water treatment process, it is widely used in oxidation ditch pushing flow, stirring of various biochemical tanks, and can also be used for river antifreeze, landscape water circulation, etc. The low-speed thruster consists of a submersible motor, a reduction device, a blade slurry, and an installation system. Its characteristics are small matching power (1.5-7.5KW), low speed (36-135R/MIN), large blade diameter (1000-2500MM), low-speed rotation, generating large volume flow field, and wide service range. The swept banana shaped blade pulp design has self-cleaning function and is precision cast from polyurethane or aluminum alloy material. It has the characteristics of light weight, high strength, and corrosion resistance. Its excellent friction performance can ensure good damping effect with the liquid at low speeds, creating a soft water flow. In addition to the functions of pushing and creating water flow, this series also has the function of stirring.
