How to choose the model and configuration of a nitrogen booster pump

At present, the use of nitrogen in China is becoming increasingly diversified. Nitrogen, as an inert gas, has higher safety and stability, and is mostly used in various occasions such as gas spring filling, nitrogen protection, gas assistance, and airtightness testing. However, with the diversified application of nitrogen, its pressure gradually cannot meet the requirements of high-pressure use. At this time, it is necessary to carry out secondary pressurization of nitrogen, and a booster pump must be selected for pressurization. Below, the editor will explain how to select a nitrogen booster pump.

The sources of nitrogen are generally divided into nitrogen generator and steel cylinder gas, one is low-pressure gas at 4-6 bar, and the other is high-pressure gas at around 13MPA. The nitrogen gas in the nitrogen generator is pressurized by a first stage booster pump, and the pressure can reach 8MPA. No matter how high the pressure is, a two-stage booster pump will be used. The initial pressure of a nitrogen cylinder is relatively high and can be directly pressurized using a primary booster pump.

The driving source of pneumatic nitrogen booster pump relies on compressed air. The model of booster pump is generally determined according to the structure and boosting ratio of the booster pump. Its structure can be divided into single-stage single acting, single-stage double acting, and multi-stage single acting. Single stage single action refers to a booster pump with only one driving cylinder and one boosting cylinder, generally used for low, medium, and low flow boosting. Single stage double acting refers to a driving cylinder and two boosting cylinders, which are commonly used for high flow and low-pressure boosting to high-pressure applications. Multi stage single action is composed of more than one driving cylinder and one boosting cylinder, commonly used for ultra-high pressure boosting of nitrogen cylinders. Boost ratio refers to the ratio of high-pressure output to the driving gas source. If the ratio is 2:1 and the driving gas source pressure is 0.5MPA, then the high-pressure output pressure is 1MPA. 5: If it is 1, it will be 2.5MPA (for more details, you can inquire with engineers from Taizhou Feentor). The model explanation of ZTA02 is Taizhou Feentor gas booster pump single-stage single action double boost ratio single pump.

After knowing what model and specifications to choose, it is also necessary to select accessories according to the on-site usage environment and actual usage situation. For example, as long as the pressure is reached for punching and canning, a single pump with a combination of two can be used. In places where stable pressure output is required, such as nitrogen purging and nitrogen assistance, a buffer tank should be connected to store the pressurized nitrogen gas and then output it through a pressure reducing valve to ensure its stable pressure. My personal suggestion is to stop seeking professional advice before making a purchase or purchase to prevent making the wrong choice.
