A kind of high-pressure oil pipe strengthening equipment

Abstract

The invention relates to a strengthening device, in particular to a strengthening device for components with high pressure. The purpose of the present invention is to provide a device for strengthening the inner wall of the high-pressure oil pipe to improve the pressure-bearing capacity of the pressure-resistant parts and relatively improve the pressure fatigue life of the high-pressure oil pipe. In order to achieve the above-mentioned purpose, the present invention is achieved in the following way: it comprises a casing, a high-pressure strengthening chamber and a driving system, the high-pressure strengthening chamber is connected with the driving system through oil pipes, the casing is provided with a movable protective door, and the movable protective door is located on The two upper and lower guide rails are used for lateral movement, and an oil pan is installed at the lower part of the chassis. The high-pressure strengthening chamber is built with an oil delivery pipe and at least one connecting tee, which is installed on the mounting frame. The driving system is composed of an air-driven booster pump, an oil tank and a driving air system. The invention is specially designed for strengthening the inner wall of the high-pressure metal pipe, and has a reasonable, tight and compact structure, strong practicability, wide application range and good development prospects.

Description

technical field [0001] The invention relates to a strengthening device, in particular to a strengthening device for components with high pressure. Background technique [0002] High-pressure oil pipes are widely used in various fields of the national economy. Due to the need to adapt to the requirements of various working conditions, there are a large number of high-pressure oil pipes. At present, my country has become one of the countries with the largest output and market demand for high-pressure oil pipes in the world. However, most of my country's high-pressure oil pipe industry is small and medium-sized enterprises, good and bad are mixed. Compared with other domestic machinery industries, there is a big gap in terms of equipment and technical level. Therefore, in major petrochemical, nuclear power, oil and gas long-distance pipelines In engineering projects, the supporting high-pressure oil pipes are mainly imported. [0003] The fuel system of a diesel engine plays a ...

AI Technical Summary

Problems solved by technology

[0003] The fuel system of a diesel engine plays a very important role in the operation of the whole machine, and the requirements for the oil pipes in the fuel system are also getting higher and higher. Because of the opening and closing of the injector needle valve when the diesel engine is working, the high-pressure oil pipes are subjected to high-pressure pulse loads and Due to high-frequency vibration, failures such as leakage of pipe joints and fatigue rupture of oil pipes often occur, and high-pressure fuel pipe ruptures or leakage splashes onto hot surfaces such as turbochargers and exhaust pipes, causing fires in machinery spaces, causing damage to ship property and Endangering the lives of personnel has attracted the attention of the International Maritime Organization (IMO). Therefore, the safety of high-pressure oil pipes is very important and cannot be ignored; this makes the safety of high-pressure oil pipes there are many hidden dangers
