Full-vacuum pump pool

Abstract

The invention discloses a full-vacuum pump pool, which relates to the field of mechanical technologies. By adopting a 'full vacuum' key technology, the full-vacuum pump pool is characterized in that a flange plate of a vacuum male flange of a liquid outlet is fixedly connected with a flange plate of a vacuum female flange of the liquid outlet, the flange plate of the vacuum female flange of the liquid outlet is fixedly connected with a flange plate of an upper cover of a vacuum large flange, the flange plate of the upper cover of the vacuum large flange is fixedly connected with a flange plate at the upper end of a vacuum tank body of the pump pool, the vacuum tank body of the pump pool is fixedly connected with a vacuum female flange of an air return port and a vacuum female flange of an liquid inlet, a flange plate of the vacuum female flange of the air return port is fixedly connected with a flange plate of a vacuum male flange of the air return port, a flange plate of the vacuum female flange of the liquid inlet is fixedly connected with a flange plate of a vacuum male flange of the liquid inlet, the vacuum tank body of the pump pool is fixedly connected with a vacuum seal joint of the tank body of the pump pool, the upper cover of the vacuum large flange is fixedly connected with a vacuum seal joint of the upper cover of the large flange, and a connecting tube at the lower end of the vacuum female flange of the liquid outlet is fixedly connected with a liquid outlet pipe of a low-temperature immersed pump. The full-vacuum pump pool disclosed by the invention is applied to liquefied natural gas transportation and is good in vacuum heat-insulating property as well as safe and reliable.

Description

technical field [0001] The full vacuum pump pool of the present invention relates to the technical field of machinery; in particular, it relates to the technical field of container machinery accompanied by power under a certain pressure; in particular, it relates to the technical field of full vacuum pump pools. Background technique [0002] The so-called pump pool is a device that installs the cryogenic submersible pump in the pump pool tank filled with liquefied natural gas. Since the pump pool tank is filled with liquefied natural gas like a pool, the cryogenic submersible pump will be installed The pump pool tanks are collectively referred to as the pump pool; the pump pool is not only an image name, but also a uniform, dedicated and professional name used in the industry. The main purpose of the pump pool is: to input LNG to various vehicles using LNG, to input LNG loaded in the tanker to the LNG gas station, to input LNG into the tanker from the parent station (so as t...

AI Technical Summary

Problems solved by technology

The current pump pool has some deficiencies, defects and disadvantages, such as simple structure and lack of scientific rationality, heat insulation treatment for the pump pool tank body, certain safety hazards, poor vacuum insulation performance, and not beautiful enough.
