Description

TECHNICAL FIELD

[0001] The utility model relates to water vapor trapping pump technical field, concretely is a kind of ultra-low temperature water vapor trapping pump phase separator pipe structure. BACKGROUND

[0002] In the field of ultra-low temperature water vapor trapping pump, the design of phase separator pipe structure is crucial, as it directly affects the efficiency and reliability of the equipment. In existing technology, the pipe structure of the first-stage phase separator has some significant drawbacks that limit the further improvement of the device performance. In existing technology, the pipe inlet of the first-stage phase separator and the gas phase outlet are both equipped with two 8mm copper pipes. This design results in a thin pipe, which limits the flow rate. In a high-efficiency trapping pump, a larger flow rate is necessary to ensure that water vapor can be effectively separated and trapped. A thin pipe limits this process, which can lead to a decrease in the performance of the device under high load.

[0003] Since the first-stage phase separator assembly is composed of three phase separators in parallel, this results in an increase in the number of pipes. The design of multiple pipes not only increases the difficulty of welding, but also poses challenges during maintenance and repair. SUMMARY

[0004] The utility model aims at overcoming the insufficient of prior art, provide a kind of ultra-low temperature water vapor trapping pump phase separator pipe structure, to solve the first-stage phase separator pipe that the existing ultra-low temperature water vapor trapping pump is used inside, thin, limited flow rate and the first-stage phase separator assembly is three phase separators and is formed, resulting in more pipes, welding difficulty is greater.

[0005] To achieve the above-mentioned purpose, a kind of ultra-low temperature water vapor trapping pump phase separator pipe structure is designed, which includes a separator inlet pipe arranged on one side of the first-stage phase separator, a separator gas phase outlet pipe arranged on the top of the first-stage phase separator, and a separator liquid phase outlet pipe arranged on the bottom of the first-stage phase separator. The separator gas phase outlet pipe and the separator liquid phase outlet pipe are both copper pipes with a pipe diameter of 12mm.

[0006] Preferably, the ultra-low temperature water vapor trapping pump phase separator is composed of multiple first-stage phase separators in parallel.

[0007] Compared with the prior art, the utility model has the following advantages:

[0008] By changing the pipe diameter and the direction of the pipeline, the original 8mm copper pipe is changed into a 12mm copper pipe, so that the refrigerant gas-liquid separation can be realized under the condition of higher flow than before and better equipment performance, and the welding difficulty can be greatly reduced, the equipment failure rate is reduced, and by changing the traditional gas-liquid separation into six different channels and equipment into three different channels and equipment, the flow distribution is relatively more uniform, the refrigerant passes through the thicker pipeline more smoothly than the thinner one, the separation efficiency of the gas-liquid separator is increased, and the equipment performance is improved.
