Nitrogen, as an inert gas, becomes essential in industrial and research experiments. At present, the main sources of nitrogen on the market are nothing more than nitrogen generators or nitrogen cylinders. However, according to various on-site working conditions, the pressure of nitrogen must be boosted to meet the purpose of use.
Nitrogen Booster Pump, Nitrogen Pressure Booster & Gas Pumps
The nitrogen booster pump is a kind of pneumatic booster pump. The low air pressure of the large area piston is used to generate the high hydraulic pressure of the small area piston.
The main advantage
- High output pressure: the maximum pressure can reach 560Mpa
- Wide range of use: the working medium can be hydraulic oil, water and most chemically corrosive liquids, and has high reliability and long maintenance-free life.
- Wide output range: For all types of pumps, only a small air pressure is required to work smoothly. At this time, a small flow rate is obtained, and different flow rates can be obtained after adjusting the intake air volume.
- Flexible application: choose different types of pumps to obtain different pressure areas.
- Easy to adjust: within the pressure range of the pump, adjust the regulating valve to adjust the intake pressure, and the output hydraulic pressure can be adjusted steplessly accordingly.
- Automatic pressure maintenance: No matter what causes the pressure of the pressure maintenance circuit to drop, it will automatically start to supplement the leakage pressure and keep the circuit pressure constant.
- Safe operation: It is driven by gas, without arc and spark, and can be used in dangerous places.
Features and Applications
- Driven by a variety of gases: compressed air, nitrogen, water vapor, natural gas, etc. can be used as the driving source of the pump.
- Wide range of applications: In the industrial field, it is used for clamping machine tool chucks, accumulator inflation, high-pressure bottle inflation, and conversion of reduced-pressure gas to high-pressure gas, etc. Where the pressure of the air source is not high enough, whether it is a machine or a test device, a booster pump can be used.
- Automatic pressure maintenance: No matter what causes the pressure of the pressure maintenance circuit to drop, the booster pump will automatically start to supplement the leakage pressure and keep the circuit pressure constant.
- Safe operation: It is driven by gas, without arc and spark, and is completely used in places with flammable and explosive liquids or gases.
When our nitrogen comes from a nitrogen generator, the nitrogen pressure is generally in the range of 4Bar-6bar, and the common situations are as follows:
The first one, the nitrogen pressure used on site is not too high, below 80bar:
This working condition is relatively simple, as long as a relatively simple single-stage high-pressure nitrogen booster pump is selected. Someone also asked what is “single stage”? A single-stage booster pump actually refers to a booster pump that can reach the working pressure with one boost.
The second type, the on-site use pressure is very high, above 80Bar:
- It is possible to consider directly using a two-stage booster pump. Someone also asked what is “double level”? As the name implies, it is similar to the “single-stage” booster pump mentioned above. “Double-stage” means that the booster pump has two booster cylinders. Low-pressure nitrogen first enters the low-pressure booster cylinder to boost once, and then passes through the high-pressure pipeline. It is sent to the booster cylinder at the other end for the second booster. The disadvantage of this solution is that the flow rate is relatively small. If there is a requirement for the flow rate, you can consider using the second solution below.
- An integrated system with two single-stage booster pumps connected in series can be considered. Specifically, after the first low-pressure nitrogen booster pump performs boosting work, the nitrogen is stored in the gas storage tank for the next medium-pressure or high-pressure nitrogen booster pump to use as the initial pressure, so that the flow rate will be much larger. In addition, it also depends on the specific working conditions and use environment of the site.
