Submersible thruster

Overview of submersible thrusters

As one of the key equipment in water treatment processes, submersible thrusters can achieve homogenization and flow requirements for solid-liquid two-phase flow and solid-liquid gas three-phase flow in the biochemical process. It consists of submersible impellers and installation systems. The submersible thruster is a directly connected structure. Compared with traditional high-power motors that reduce speed through reducers, it has advantages such as compact structure, low energy consumption, and ease of maintenance and upkeep. The impeller is precision cast or stamped, with high precision, thrust, and a simple and beautiful linear shape. This series of products is suitable for places that require solid-liquid mixing and blending.

Performance characteristics of submersible thrusters

1QJBThe submersible thruster has a compact structure, small volume, light weight, simple operation and maintenance, easy installation and maintenance, and long service life.

2. The impeller has the best hydraulic design structure, high working efficiency, and the swept back blades have self-cleaning function to prevent debris entanglement and blockage.

3. Mixing with the aeration system can significantly reduce energy consumption, increase oxygen filling capacity, and effectively prevent sedimentation.

4. The insulation level of the motor winding isFGrade, protection level isIP68Select imported disposable lubrication and maintenance free high-quality bearings with oil chamber leakage

The dew detection and unique patented motor winding overheating protection and anti condensation device make the operation of the motor safer and more reliable.

5. Two independent mechanical seals, the friction material of the mechanical seal is corrosion-resistant tungsten carbide.

6. The unique cable sealing design eliminates the hidden danger of cable leakage.

7. The standard components adopt point solution separation technology, which can effectively prevent corrosion.

Application and conditions of submersible thrusters

1) The maximum medium temperature shall not exceed 40℃；

2) The medium'sPHValue in5-9between;

3) Liquid density not exceeding 1.15kg/cubic meter;

4) Long term diving operation, with a diving depth generally not exceeding20m.

Attention to maintenance of submersible thrusters

1. Replace all worn components.

2. Check all screw joints.

3. Check the oil level and condition.

4. Check if there is any liquid present in the stator cavity.

5. Check the cable entry and cable condition.

6. Functional inspection of the starting device.

7. Check the direction of rotation.

8. Check the lifting device and guide rod.

9. Check the electrical insulation condition.

10. Replace all items disassembled for inspectionOType sealing ring.

11. Check and flush the sealing ring and its surroundings.

Installation of submersible thruster

The specialized installation system for submersible thrusters can quickly install and disassemble them without the need to discharge sewage from the pool.

When the pool is deepH<4Mi Shi suggests using installation system one.

The diving depth of the submersible thruster can be adjusted vertically as needed, and the maximum angle of rotation around the guide rod within the horizontal range is positive or negative60The connection surfaces between the lifting system base, support frame, and lower bracket and the pool are fixed with expansion bolts without the need for reserved holes.

The installation system uses guide steel ropes instead of guide rods, which has the characteristics of convenient transportation and simple on-site installation. This system fundamentally avoids the situation of guide rod bending and deformation caused by transportation, which affects normal use, and effectively improves the phenomenon of inability to lift normally due to installation errors of guide rods when the pool is too deep. Under the installation conditions of a cantilevered pool roof, it appears more convenient and reliable to operate.

Notice for Ordering Submersible Thrusters

Please provide the pool depth when the customer places an orderHAnd the pool diagram is used to determine the size of the guide rod or guide wire during factory processing. The material of the installation system is made of stainless steel (or carbon steel). In addition to the guide rod or guide steel lifting base in the installation system, multiple submersible thrusters can share a set of lifting devices. If you need a submersible thruster or submersible aerator. You can contact us.

Maintenance suggestions and operation methods for submersible thrusters

Firstly, ensure that all screws, bolts, and nuts are tightened and check the lifting device/The condition of the buckle, lifting chain, and rope should be checked in a timely manner, and worn or damaged parts should be replaced or repaired. The guide rod should be checked for verticality. If worn parts hinder the normal operation of the mixer, they should be replaced.

Secondly, by disassembling the oil drain screw, the condition of the oil can be checked to determine if there is any leakage. Install the oil injection screw for sealing. Due to the separation of oil and water, if liquid flows out first, it may indicate a leak. Tap the screw until clean oil flows out. If the oil leakage is less thanO.1ml/hMechanical seals are considered normal. Inject new oil into the oil chamber again; If the oil leakage is greater than0.1ml/hRe inject oil; After running the submersible mixer for one week, check the oil condition again; If the oil leakage is still greater than0.1ml/hIt may be due to damage to the mechanical seal ring; Also, pay attention to checking if the screw plug is tight enough. If there is a leak, the stator chamber will be compressed and covered with a cloth to prevent oil from splashing out. If liquid seeps into the stator chamber, tilt the equipment to allow the liquid in the stator chamber to flow out.
