Description

Liquid pump structure for full liquid expander

Technical Field

The utility model relates to the technical field of expander liquid pumps, in particular to a liquid pump structure for a full liquid expander.

Background Art

A liquid expander is a mechanical device that can convert the energy of a liquid into other forms of energy. Its basic principle is to use the incompressibility of the liquid to expand the liquid under high pressure and do work, thereby realizing energy conversion. Liquid expanders can be divided into two types: piston expanders and centrifugal expanders. Piston expanders are mainly used for the liquefaction of high-pressure gases, while centrifugal expanders are often used for the expansion process of liquids. A liquid pump is a mechanical device used to transport liquids. It can transport liquids from low places to high places or in pipelines. Liquid pumps are usually driven by electric motors or other power sources, and use various types of blades or pistons to transport liquids.

However, the use of current liquid pumps needs to consider the heat dissipation holes of the device. However, the heat dissipation of traditional liquid pumps is mainly to cool down the entire liquid pump through heat exchange with the outside world. However, this cooling method needs to consider the problem that the temperature inside the liquid pump is much higher than the outside world, which is easy to cause damage to the equipment inside the liquid pump. Therefore, it is necessary to propose a liquid pump structure for a full liquid expander.
