AI Technical Summary

Technical Problem

Existing pressurization equipment can only pressurize in one pass, resulting in low pressurization efficiency and affecting the efficiency of filling the aerosol can with propellant.

Method used

A vertical booster pump was designed, including a drive cylinder and a booster cylinder. The reciprocating motion of the pistons in the drive cylinder and the booster cylinder enables bidirectional pressurization of the material gas. By utilizing the coordinated motion of the drive cylinder and the booster cylinder, pressurization of the material gas in any direction is cleverly achieved, thereby improving the booster efficiency.

Benefits of technology

It greatly improves the pressurization efficiency and the efficiency of filling the aerosol can with propellant, and has good application prospects.
