Annular deep sea pressure compensator

Abstract

The invention relates to an annular deep sea pressure compensator. The annular deep sea pressure compensator is characterized in that the annular deep sea pressure compensator comprises an annular bellows, a compensator annular outer casing body and an elbow pipe; the annular bellows is arranged in the compensator annular outer casing body; the elbow pipe is arranged on the inner circumference ofthe compensator annular outer casing body; the elbow pipe is connected with a use device; the compensator is annularly wound around the use device; and the internal space of the compensator is communicated with the internal space of the casing body of the use device, and is filled with compensating oil. According to the invention, the longitudinal height dimension of the use device is reduced as much as possible under the condition that sufficient compensation capacity is ensured, and at the same time the casing body provides rigidity protection or corrosion protection for the compensator.

Description

technical field [0001] The invention relates to a pressure compensator, in particular to an annular deep-sea pressure compensator used in the field of underwater production operation equipment to perform pressure compensation on the inside of the sealed shell of underwater equipment. Background technique [0002] The basic structure of underwater operation production equipment is to install the equipment in a sealed shell, and the gap between the equipment and the shell is filled with insulating oil. Underwater production equipment needs to bear seawater pressure and heat simultaneously in the process of working in deep sea. It works on the deep seabed and bears the pressure of seawater. The equipment loss is dissipated outward in the form of heat, so the underwater production equipment is also subjected to heat. While the equipment is going through different working conditions, the insulating oil inside the sealed casing will also expand with heat and contract with temper...

AI Technical Summary

Problems solved by technology

When the volume of the equipment is large, the amount of compensation required will increase accordingly, so the number of pressure compensators required will also increase accordingly, which will cause the overall structure of the production equipment to be complicated, difficult to maintain, and high manufacturing costs. series of questions
