The pressurization ratio of the gas booster pump is the area ratio of the driving piston to the high-pressure piston (or plunger), which is an important factor determining the pump output pressure. For a pump, its pressurization ratio is fixed, and its output pressure is the product of the driving pressure and the pressurization ratio. The customer only needs to select the product with the appropriate pressure ratio according to the pressure requirements of the application. So how to choose the gas booster pump with the right pressure ratio? Direct examples are as follows:
1. The current air supply pressure of a customer is 6bar. To raise it to 30bar for new equipment, divide 30 by 6=5, that is, use a 5x gas booster pump to raise the air supply pressure to 30bar. Of course, there is another important factor in the selection: flow requirements after high pressure; Since the customer's flow requirement after high pressure is 6L/min, and the flow requirement after high pressure of 5 times of gas booster pump is 7L/min, it can meet the customer's flow requirement after high pressure, and if not, it can not be used. I won't go into it here.
2. When the air supply pressure in the workshop of a company is 6 bar, most of the equipment can be used in production; However, a device requiring more atmospheric pressure (10bar) has recently been purchased. There are two schemes, one is to purchase a large air compressor and the other is to purchase a gas booster pump. Obviously, the former chooses the latter scheme because of its high cost and high noise.
Scheme implementation: the customer's current air source pressure is 6bar, which needs to be increased to 10bar. The customer can be recommended to use twice the gas booster pump (the current air source pressure is 6bar multiplied by 2=12bar, meeting the requirements of 10bar air source pressure). Of course, there is also a question whether there are special requirements for the flow after high pressure. The gas booster pump that is 2 times larger can be subdivided into the one that is 2 times larger and the one that is 2 times smaller. The difference is that the flow after high pressure is 80 L/min for the one that is 2 times larger and 40 L/min for the one that is 2 times smaller.
Note: As the higher the pressurization ratio of the gas booster pump is, the higher the corresponding inlet pressure is, so customers should pay attention to the small inlet pressure of the pressurized gas when selecting and using it.
