Description
Technical Field
The invention relates to a pressure compensating device, in particular to a reducing differential pressure plunger type pressure boosting compensation device.
Background
After the deep sea pressure maintaining sampling equipment completes the submarine sampling operation and performs pressure maintaining sealing on the pressure maintaining storage tank for storing the collected sample, in the process of returning to the water surface from the deep sea bottom, the external pressure born by the deep sea pressure maintaining sampling equipment gradually reduces the water depth pressure corresponding to the original submarine sampling operation point to the atmospheric pressure of the water surface, at this time, the pressure difference is generated inside and outside the pressure maintaining storage tank of the deep sea pressure maintaining sampling equipment, so that the pressure maintaining storage tank of the deep sea pressure maintaining sampling equipment is expanded and deformed under the action of high-pressure seawater sealed in the pressure maintaining storage tank, the pressure in the pressure maintaining storage tank is reduced, and in order to compensate the pressure drop caused by the expansion deformation of the pressure maintaining storage tank, a pressure compensating device (device) is required to be arranged for the pressure maintaining storage tank. However, currently existing pressure compensating devices, such as spring-loaded plunger type compensating devices (zl201220714056. X), bellows type pressure compensating devices, pre-filled with nitrogen (or pre-filled with other inert gas) type pressure compensating devices, store a pressure opposite to the water depth pressure of the operating point when the operating point is subjected to the water depth pressure corresponding to the operating point at the sea bottom sampling operating point, and when the deep sea pressure maintaining sampling equipment returns to the water surface from the sea bottom, the pressure stored by the pressure compensating devices compensates the pressure of the pressure maintaining storage tank of the deep sea pressure maintaining sampling equipment, and since the maximum storage pressure of the pressure compensating devices is the water depth pressure corresponding to the sea bottom sampling operating point, the pressure compensating devices themselves are expanded and deformed due to the internal pressure, and after the pressure compensating devices are utilized to perform pressure compensation on the pressure maintaining storage tank of the deep sea pressure maintaining sampling equipment, the pressure inside the pressure compensating devices and the pressure maintaining storage tank of the deep sea pressure maintaining sampling equipment will be smaller than the water depth pressure corresponding to the water depth pressure of the operating point, so that the high-level standard of the in-place sea pressure maintaining sampling equipment (sea bottom sampling operation point water depth maintaining requirement of the storage tank of the deep sea pressure maintaining sampling equipment is not met.
