Abstract

The invention discloses a detection device for simulating the sealing property of seal rings in rotary motion in a deep sea environment. The detection device comprises a high-pressure cylinder, wherein a piston is arranged in the high-pressure cylinder; a group of testing seal rings are symmetrically arranged at two ends of the piston; one end of the piston is connected with a vibration motor; a rotating speed sensor is fixed at an exhaust port of the high-pressure cylinder; a magnet is fixed on a motor shaft; a hydraulic device A is connected with a drive motor; leakage sensors are symmetrically distributed at the bottoms of two ends of the high-pressure cylinder; the middle position of the high-pressure cylinder is connected with a hydraulic device B through high-pressure tubes; a pressure sensor and a temperature sensor are arranged on each high-pressure tube; the rotating speed sensor, the pressure sensors, the temperature sensors and the leakage sensors all are connected with a controller; and the controller is connected with the hydraulic device A and the hydraulic device B. According to the detection device, the high-pressure cylinder is provided with different environmentsthrough the hydraulic device B, and the piston in the high-pressure cylinder carries out rotary motion through the hydraulic device A and the motor shaft in the drive motor, so that the sealing property of the seal rings in different environments is detected through the leakage sensors in the rotary motion process of the piston.

Description

technical field [0001] The invention relates to the field of marine engineering, in particular to a detection device for simulating the sealing performance of a rotary motion sealing ring in a deep sea environment. Background technique [0002] The ocean is rich in resources such as oil and gas, organisms, and metal minerals, and deep-sea equipment plays a vital role in the development of these resources. In the process of developing and utilizing deep-sea biological resources in the deep sea, deep-sea high-pressure sealing is an important basis for breaking through the deep-sea high-pressure barrier to obtain deep-sea biological resources, especially the electromagnetic-based control system, which has stricter requirements on the sealing environment. With the development of my country's deep-sea equipment technology, the requirements for the sealing performance of seals are getting higher and higher. At present, the sealing performance testing device of the sealing ring is...

AI Technical Summary

Problems solved by technology

At present, the sealing performance testing device of the sealing ring is basically limited to the analysis in a single environment, and there are few sealing performance testing devices for the sealing ring in the simulated deep sea environment

In view of the special operating environment of deep-sea equipment, once the sealing performance of the system’s sealing structure fails during deep-sea operations, not only will the operation fail to be completed, but it may also cause potential safety hazards
