GB/T 36896.3-2018 in English

GB/T 36896.3—2018 Standard Overview

GB/T 36896.3—2018 "Lightweight Cable Remote Control Underwater Robot Part 3: Ducted Propeller Thruster" is a technical specification for underwater robot propulsion systems, mainly involving the classification, requirements, test methods and inspection rules of ducted propeller thrusters. This standard applies to the design, production, procurement and application of underwater robots.

Background of Standard Formulation

With the development of marine technology, underwater robots play an important role in marine resource exploration, environmental monitoring and other fields. Ducted propeller thrusters are the core components of underwater robots, and their performance directly affects the operating efficiency and reliability of the equipment. This standard aims to standardize the technical requirements of thrusters and ensure product quality.

Technology Evolution Analysis

In recent years, underwater robot technology has gradually developed towards lightweight and intelligent directions. The design of ducted propeller thrusters focuses more on high efficiency and reliability, while combining hydraulic and electric drive technologies to meet the needs of different application scenarios.

Comparison of standard frameworks

Interpretation of core requirements

Appearance and structure: The thruster design must be scientific and reasonable, easy to operate and maintain. All connectors should be firm and reliable, and the surface treatment should be beautiful and free of defects.

Performance requirements: The thruster dynamic balance level must comply with the G6.3 standard of GB/T 9239.1-2006. The speed control accuracy level is divided into four levels, see the following table for details:

Test methods and inspection rules

The standard specifies detailed test methods, including dynamic balancing test, thrust measurement, etc. The inspection is divided into factory inspection and type inspection, see Table 2 for specific items:

Implementation Suggestions

Enterprise implementation measures: It is recommended that production enterprises strictly follow the standard requirements, strengthen production process control, and ensure that products meet the technical indicators. At the same time, a sound quality inspection system should be established and equipped with professional testing equipment.

Technological innovation direction: On the basis of meeting existing standards, it is recommended that enterprises focus on the research and development of high-efficiency thrusters, explore intelligent and modular designs, and enhance product competitiveness.
