The submersible thruster can operate continuously under the following conditions: 1. The maximum medium temperature does not exceed 40 ° C; The pH value of the two media is between 5-9; 3. The density of the medium does not exceed 115KG/M ^ 3; Long term diving operation of low-speed thrusters, with a diving depth generally not exceeding 20 meters. The selection of submersible thrusters is a complex task, and the correctness of the selection directly affects the normal use of the equipment. As a principle of selection, it is necessary to ensure that the mixer can fully perform its mixing function in the appropriate volume, which can generally be determined by the flow rate. According to the different process requirements of sewage treatment plants,Submersible thrusterThe flow rate should be ensured to be withinBetween 0.15~0.3m/s, if the flow velocity is lower than 0.15m/s, the push flow mixing effect cannot be achieved. If the flow velocity exceeds 0.3m/s, it will affect the process effect and cause waste. So before selecting, first determine the location where the low-speed thruster will be used, such as sewage tanks, sludge tanks, and biochemical tanks; Next are the parameters of the medium, such as suspended solids content, viscosity, temperature, and pH value; Also, the shape and depth of the pool.

The required matching power for a submersible thruster is determined by the volume, density of the mixed liquid, and mixing depth, and one or more mixers are used depending on the specific situation. As the quality of treated water approaches that of uncontaminated water, the practical benefits of water regeneration and reuse become very apparent.Submersible thrusterThe level of treatment and the quality of treated water make it economically valuable and a part of water resources. With the increasing application of advanced technologies such as activated carbon adsorption, advanced oxidation, and membrane technology in recycled water, the quality of recycled water has been able to meet or exceed traditional drinking water standards in all measurable indicators. Nowadays, water regeneration or purification

Installation CAD drawing of submersible thruster

The maintenance of submersible thrusters is currently a concern for various companies, but it needs to be carried out in many steps. This article will talk about the details that cannot be ignored after the installation of low-speed submersible thrusters.

1、 Inspection and adjustment of the clearance between the impeller and the front guard plate. The general gap should be between 0.75-1.0mm.
2、 Adjustment of the rotation direction of the electric motor. The rotation direction of the electric motor should be consistent with the specified direction, and reverse rotation is not allowed, otherwise it may cause the impeller of the low-speed submersible thruster to trip or damage other components. The low-speed submersible thruster should be completely disconnected from the motor before checking the direction of the motor

3、 Adjustment of transmission device. For the transmission using elastic column pin coupling, the column pin and protective cover should be properly installed. For low-speed submersible thrusters that use belt transmission, the belt should be properly attached, the tension adjusted, and the protective cover installed.

4、 Adjustment of fasteners. All fasteners should be tightened with a wrench.

5、 The specifications, quality, and quantity of lubricating grease should comply with the provisions of the equipment technical documents, and parts with pre lubrication requirements should be pre lubricated according to the provisions of the equipment technical documents.

6、 Clean up the tools and debris placed on the low-speed submersible thruster unit to prevent accidents during its operation.

7、 Before starting the low-speed submersible thruster, the inlet and outlet valves of the low-speed submersible thruster should be in the following open positions: inlet valve: fully open; The outlet valve of the centrifugal low-speed submersible thruster is fully closed, while the other low-speed submersible thrusters are fully open (when the mixed flow low-speed submersible thruster is vacuum guided, the outlet valve is fully closed).
