Abstract

The invention relates to the technical field of hydraulic transmission and the technical field of cooling circulation and aims to provide a cooling-circulation pressure maintaining system provided with two hydraulic pumps and used for pressure-maintained transferring. The cooling-circulation pressure maintaining system comprises a cooling system, an electromagnetic valve system and a circulation pressure maintaining system, wherein the cooling system, the electromagnetic valve system and the circulation pressure maintaining system are connected through pipelines. The cooling system comprises acooling device, a cold water box and a first refrigerator. The electromagnetic valve system comprises a first two-position and two-way electromagnetic valve, a second two-position and two-way electromagnetic valve, a third two-position and two-way electromagnetic valve and a fourth two-position and two-way electromagnetic valve. The circulation pressure maintaining system comprises a pressure-maintained transferring system and a secondary pressure-maintained transferring system. According to the cooling-circulation pressure maintaining system provided with the two hydraulic pumps and used forpressure-maintained transferring, the functions of pressure maintaining and temperature control of natural gas hydrate samples are integrated, the two most important parameters for in-situ maintaining of the natural gas hydrate samples are ingeniously controlled, and the cooling-circulation pressure maintaining system is high in novelty and has important reference significance for subsequent designing of a natural gas hydrate sample transferring system.

Description

technical field [0001] The invention relates to the fields of hydraulic transmission technology and cooling cycle technology, in particular to a dual-hydraulic pump cooling cycle pressure-holding system for pressure-holding transfer. Background technique [0002] In the context of the depletion of onshore fossil fuels and other resources, and the lack of emerging wind energy, solar energy and other energy sources as the main energy supply, seabed resources as a strategic reserve have attracted more and more international attention. Among them, natural gas hydrate is more and more valued by our country because of its huge reserves and high quality. However, natural gas hydrate will decompose rapidly after leaving the in-situ high-pressure and low-temperature environment. If it is not treated with heat preservation and pressure, high-purity natural gas hydrate cannot be extracted for subsequent analysis or processing. Based on the characteristics of natural gas hydrate, the e...
