The design and production of underwater electric cylinders face many challenges, the main difficulties include:

1. Material selection:

It is necessary to use materials with high strength, corrosion resistance and good electrical conductivity, such as stainless steel or special alloys, to ensure long-term stable underwater operation of the underwater electric cylinder.

2. Waterproof seal:

- An efficient waterproof seal for the underwater electric cylinder is key, requiring precision O-rings, gaskets and special sealants to prevent water intrusion.

3. Electrical insulation:

In the underwater environment, it is very important for the underwater electric cylinder to maintain good electrical insulation, and special insulation measures need to be taken, such as the use of insulation coatings and isolation layers.

4. Stress Resistance:

- The design needs to consider the impact of water pressure on the structure of the underwater electric cylinder to ensure that the underwater electric cylinder can withstand the corresponding pressure at different depths.

5. Corrosion protection:

Special anti-corrosion treatment is required on the surface of the underwater electric cylinder, such as electroplating, spraying or using sacrificial anode protection to extend the service life.

6. Electromagnetic interference:

- In the underwater environment, electromagnetic signals may be interfered with, and electromagnetic compatibility needs to be considered in the design to ensure that the control system of the underwater electric cylinder is stable and reliable.

7. Maintenance and overhaul:

The maintenance and overhaul of underwater electric cylinders is relatively difficult, requiring the design of components that are easy to remove and replace, as well as remote monitoring and fault diagnosis systems.

8. Cost control:

- Due to the use of high-performance materials and complex manufacturing processes, the manufacturing cost of underwater electric cylinders is high, requiring cost control while ensuring performance.

9. Environmental adaptability:

- Need to ensure that the underwater electric cylinder can adapt to different underwater environments, such as fresh water, sea water, temperature changes, etc.

In the design and production of underwater electric cylinder, it is necessary to consider the above difficulties comprehensively, and take corresponding technical measures to ensure the reliability and durability of underwater electric cylinder in the underwater environment.
