Embodiment Construction

[0019] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] The present invention is a hydraulic source device capable of working at full sea depths, including a compensation chamber part (1), a motor pump part (2), and a hydraulic oil circuit control part (3). The three are connected by flanges to ensure sealing and use The flange connection method can facilitate installation, and it is also convenient for future transformation and upgrading of the hydraulic source. Through the coordinated work of the three parts, the stable work of the hydraulic source under the high-pressure condition of the deep sea can be realized.

[0021] Such as figure 1 In the example shown, the compensator part 1 adjusts the internal pressure of the hydraulic oil source, so that the pressure of the oil tank inside the hydraulic oil source is the same as the external pressure, and at the same time, it can reduce the ...

Abstract

The invention discloses a hydraulic source device with the whole sea deep working capacity. The hydraulic source device mainly comprises a compensator cavity part, a motor pump part and a hydraulic oil circuit control part. The compensator cavity part utilizes a piston compensator to provide a stable pressure environment for internal devices; the motor pump part is internally provided with a motorpump to provide a stable high-pressure oil source; and the hydraulic oil circuit control part is internally provided with an oil circuit valve block for controlling. According to the hydraulic sourcedevice, most components and devices are soaked in hydraulic oil, the hydraulic source device can be used under the deep sea high-pressure condition and can provide a high-pressure hydraulic source for a hydraulic system under the deep sea high-pressure environment, the reliability and stability of the hydraulic source under the deep sea high-pressure environment are improved, and support is provided for the research of marine engineering hydraulic equipment under the deep sea condition.

Description

technical field [0001] The invention relates to a hydraulic source device capable of working at full sea depth. The device can be used as a hydraulic oil source for hydraulic equipment in a deep-sea high-pressure environment. It works stably and efficiently, and is suitable for research on hydraulic equipment for deep-sea marine engineering. Background technique [0002] The deep-sea hydraulic source is the power source of each hydraulic actuator of the deep-sea manned submersible, which is equivalent to the heart of the overall hydraulic system. Its performance and stability directly determine the overall performance and reliability of the system. The deep-sea environment has extreme environmental characteristics such as high pressure, low temperature, and strong corrosion. In particular, the full-sea deep manned submersible has a large vertical working span and a wide range of external water pressure changes, which will lead to changes in the characteristics of the oil medi...
