Abstract

With the development of the technology, hydraulic technology has been widely used in various fields, and hydraulic system has become one of the most important parts of the host equipment.. However, due to the design, manufacture, installation, use and maintenance of factors, the impact of the normal operation of the hydraulic system. Therefore, to understand the working principle of the system, to understand some of the design, manufacture, installation, use and maintenance of knowledge is a hydraulic system to ensure normal operation and great play a prerequisite for hydraulic technology advantage.
This paper mainly studies the hydraulic transmission system, the design of hydraulic drive system and the overall design of the host. Design, we must proceed from the actual situation, and organically combined with various forms of transmission, give full play to the advantages of hydraulic transmission, strive to design a simple structure, reliable work, low cost, high efficiency, simple operation, convenient maintenance hydraulic transmission system.
Is introduced in this paper the development status of the at home and abroad work tools, underwater operation system, common water cutting method and cutting the pipe, and sums up the developing situation at home and abroad of diamond wire saw, put forward the idea of underwater submarine pipeline diamond wire saw cutting machine for cutting the seabed oil-gas pipeline design wire saw machine hydraulic drive and control system, and main technical parameters of the power is calculated and checked. This thesis mainly completes the following work:
1, the underwater submarine pipeline diamond wire saw cutting machine plan and analysis design.
2. The hydraulic system design of the diamond wire saw cutting machine for underwater submarine pipeline is accomplished..
3, the power source of the hydraulic system of the rope saw is finished, and the main parameters of the hydraulic execution element are calculated, and the clamp device, the tensioning device and the feeding device of the rope saw machine are designed..
4, design of underwater submarine pipeline diamond wire saw cutting machine hydraulic system principle diagram, and calculating and checking the main technical parameters of the hydraulic power source, choose the hydraulic pump, motor, control valves and other components.
5. The design of the special hydraulic system for the diamond wire saw cutting machine of underwater submarine pipeline is accomplished..
