Underwater Thrusters Designed For Depth,Multiple Specification Options

As is widely known, an underwater thruster is a device specifically designed for underwater activities. It can provide power and help divers, submarines, unmanned underwater robots (ROV), and others move rapidly in the underwater environment. Its core component is an efficient electric motor, such as a brushless DC motor. The purpose is to generate thrust through propeller or jet propulsion to push the user or vehicle forward in the water.

As the application fields of underwater thrusters become more and more extensive, including in industries such as ocean exploration, underwater work, resource development, and environmental protection detection, the demand for underwater thrusters will grow greater and the requirements will also become higher, especially in terms of unmanned underwater robots (ROV/AUV). Therefore, choosing a suitable underwater thruster has become a challenge faced by many consumers.

Today, let's briefly discuss how to choose a suitable underwater thruster.

1、Performance parameters

I. Thrust: Select the appropriate thrust according to the weight of the equipment and its intended use. Generally speaking, the greater the thrust, the stronger the performance of the equipment.

II. Power: The power should match the weight of the equipment and the operating depth. The greater the power, the higher the energy consumption and noise will be.

2、Structural characteristics

Compactness: Choose a model with a compact structure, small size, and light weight, which helps improve operational flexibility.

Self-cleaning function: The blades should have a self-cleaning function to prevent entanglement and blockage by debris and ensure long-term stable operation.

3、Installation convenience

Ease of installation: Ensure that the selected thruster is easy to install and maintain to reduce operating costs and time.

4、Service life

Corrosion resistance: Underwater thrusters are widely used in remotely operated underwater detectors (ROV) and autonomous underwater detectors (AUV). They need to withstand the high pressure and corrosive environment in the deep sea. Therefore, its corrosion-resistant design is crucial.

Service life: Choose those models that have been verified and have good durability. Products with a longer warranty period are usually more reliable.

Underwater Thrusters Designed For Depth,Multiple Specification Options

The SW and DW series underwater thrusters newly launched by CubeMars adopt a closed design. The key components of the thruster are all placed inside the sealed housing, effectively avoiding damage caused by foreign objects such as sediment and being able to cope with the complex and changeable underwater environment, meeting the application requirements of long life, corrosion resistance, and maintenance-free.

At the same time, the underwater thruster adopts a comprehensive protection design, fully considering the heat dissipation problem generated during operation. The interior is filled with high-efficiency thermal conductive materials, so that the thruster can dissipate heat through immersion in water and achieve efficient operation. The sealed housing of the thruster is strong and durable, with a maximum operating depth of 350 meters, and the maximum mooring thrust covers 7 to 25 kgf, which can meet the surface and underwater application requirements of different levels of ROV, unmanned ship, surfboard, and others.

Advantages of CubeMars DW series underwater thrusters:

1、Dive into the deep sea freely.

Small size, strong power, with mooring thrust of at least 25 kgf.

2、Precision-cast alloy, corrosion-resistant and durable.

Lightweight and high-strength aluminum alloy, wear-resistant and durable.

3、Sealing process

Threaded connection process,two-stage independent sealed cabin,and low-resistance dynamic sealing process. 

4、Shafting design

Simplify the internal structure. In many applications, it is very sturdy and operates stably and reliably.

5、Propeller and fairing

Streamlined design reduces underwater resistance to a greater extent and realizes efficient operation underwater.
