Keywords you need to know before purchasing a gas booster pump
The gas booster pump has the characteristics of high output performance and low cost, and the booster pump has fewer parts and seals and is simple to maintain and low in cost. So what are the keywords you need to know before purchasing a gas booster pump?

Pressure ratio: The area ratio of the driving piston of the gas booster pump to the pressurizing piston. Commonly used pressure ratios: 2:1, 3:1, 4:1'160:1, and so on.
Air consumption: the minimum air consumption (NL/min) required by the gas booster pump to drive the piston to determine whether the delivery capacity of the air compressor or pipeline can meet the needs of the booster pump. Under normal circumstances, the gas booster pump requires the minimum air consumption of the air compressor to be'0.6m3/min. Under the same driving air pressure, the greater the air outlet flow provided by the air compressor, the faster the gas booster pump works, and the higher the boosting rate.
Driving pressure: the pressure range of the gas booster pump driving the booster pump, the theoretical range is between 2bar~10bar, and the economical use range is between 6bar~8bar. The driving gas is used as the power source of the gas booster pump. The higher the pressure, The greater the coefficient multiplied by the boost ratio, and the greater the output pressure.
Principle of the boost ratio
The boost ratio of a gas booster pump is the area ratio of the driving piston to the high-pressure piston (or plunger), which is an important factor in determining the output pressure of the pump. For a pump, its boost ratio is fixed, and its output pressure is the product of the driving air pressure and boost ratio. Customers only need to choose the product with the appropriate boost ratio according to the pressure requirements of the application
Note: As the booster ratio of the gas booster pump is higher, the corresponding required inlet pressure is also higher, so customers should pay attention to the minimum inlet pressure of the boosted gas when selecting and using it.
How to choose a gas booster pump product with a suitable booster ratio?
As a direct example, the following are 2 examples:
1. A customer's current gas source pressure is 6 bar, and it needs to be raised to 30 bar for new equipment. Divide 30 by 6=5, that is, the gas source pressure can be raised to 30 bar by using a 5 times gas booster pump. Of course, there is another important factor when selecting the model: the flow rate requirement after high pressure; since the flow rate requirement of this customer is 6L/min after high pressure, the flow rate after high pressure of the 5 times gas booster pump is 7L/min, which can meet the flow rate after high pressure If the requirements are not met, they cannot be adopted. I will not delve into it here.
2. Before the workshop of a certain company, the air source pressure was 6 bar, which can meet the production and use of most equipment; but recently purchased a piece of equipment that requires a higher pressure (10 bar). There are 2 options, purchasing a large air compressor and purchasing a gas booster pump. The former chose the latter option because of its high cost and excessive noise.
Solution implementation: The customer's current gas source pressure is 6bar and needs to be increased to 10bar, and the customer can be recommended to use twice the gas booster pump product (the current gas source pressure is 6bar multiplied by 2=12bar, which meets the 10bar gas source pressure requirement). Of course, another question is whether there are special requirements for the flow rate after high pressure. The double gas booster pump can be subdivided into 2 times larger and 2 times smaller. The difference lies in the flow rate after high pressure. min, 40L/min for the smaller ratio of 2.
How to choose the brand of gas-liquid booster pump
How to choose a reliable gas-liquid booster pump brand? When you choose to buy a gas-liquid booster pump, you must choose a regular manufacturer, and you need to be able to understand the characteristics of different brands. This will be more pertinent for your choice, and it can also avoid affecting you.
Production and Processing Technology
Since there are more and more manufacturers producing pneumatic equipment, if you want to be able to make a reasonable choice among many gas-driven gas booster pump manufacturers, you must know whether the manufacturer's production and processing technology is reasonable and whether it has an independent factory for production. , Naturally, you can have more advantages in price positioning, and the overall cost performance will be improved. Consumers must be rational when choosing and need to consider various factors, rather than blindly choose and buy.
Quality Inspection Standard
In addition to knowing the quality of the manufacturer's production and processing, it is important to know whether the manufacturer can have extraordinary quality inspection standards, can meet the production and processing inspection requirements of the entire industry, have extraordinary after-sales service guarantees, and can solve all customer problems in a timely manner. question.

The answers to the following questions will provide the parameters for the selection of any gas booster or ProPak booster system.
1. What is the maximum pressure to be attained?
You need to know the pressure that the system will have to reach, either now or sometime in the future. This does not need to be the usual working pressure, but the maximum pressure ever needed.
2. What is the required flow rate?
You need to know the required flow rate at the required discharge pressure. This is not the flow rate at the maximum pressure, but the flow rate at the working pressure. Remember that every booster has a maximum pressure where it will stall and produce no flow, but at any pressure less than that it will produce flow. This flow reduces in quantity as the output pressure approaches the stall pressure.
3. Is the flow rate constant?
Do you have a process application where you need a constant flow at a constant pressure? If so, then this is expressed as 'x' SCFM (NM3) @ 'y' PSIG (Barg).
4. Is the flow rate decreasing?
Do you have an application where you are filling cylinders or some other vessel from a lower supply pressure to a higher storage pressure. To select the proper booster or booster system, you need to know the size of the vessel to be filled. This can be supplied in any form that can be converted to ACF.
5. What is the required fill time for the vessel?
It is very common to have an initial fill times that is unrealistic. Many people who are not
familiar with gases ask for fill times that will require uneconomic systems. Therefore it is important to think about the longest possible fill time the application can stand.
6. What is the gas supply pressure?
The performance of any gas booster is a function of the incoming gas pressure. Simply stated: 'any gas booster will only discharge the amount of gas it takes in'. The higher the inlet gas pressure, the more SCF of gas are squeezed into the gas section and
therefore the more gas discharged. Gas supply can have more than one source. Therefore it can have many combinations of flow, pressure and temperature.
7. What is the drive pressure?
This is not the initial pressure in the system first thing in the morning before all of the uses of air are operational, but rather should be the minimum that the plant experiences throughout the day. The booster may have to provide maximum performance when the drive conditions are at their worst.
8. What is the gas?
Some gases cannot be pumped with standard boosters. They may require special seals, materials of construction, venting and other considerations. This is also important when higher pressures are required in filling applications to determine the compressibility of the gas. Applications involving gas boosters will always fall into one of four categories. It is very important to clearly determine into which category a particular application fits.
a) The supply pressure is at a constant pressure (Ps) and the discharge gas is at a constant flow (Q) and pressure (Po).
b) The supply gas is from a decreasing pressure and the discharge gas is at a constant flow and pressure. It is safe to assume that the supply flow rate will decrease as the supply pressure decreases. To maintain the constant outlet flow the booster will have to increase its cycle rate.
c) The supply gas is at a constant flow and pressure and the discharge gas it at an increasing 8 pressure.. It is safe to assume that the discharge flow rate will decrease as the discharge
pressure Increases.
d) The supply gas is at a decreasing pressure and the discharge gas is at an increasing pressure. It is safe to assume that the flow rate will decrease significantly as the pressures get further apart.
