How to Choose a High-Quality Brand Air Compressor

What parameters should you consider when selecting an air compressor to ensure you choose a good and suitable one? Let's take a look below:

Ringhua Air Compressor: What to Consider When Choosing an Air Compressor – First and foremost, we must discuss the working pressure and volumetric flow rate.

When making choices, the direction is the primary consideration, followed by personal appearance and style. Specifically, let's carefully review the overview below.

(1) Selection of working pressure (discharge pressure):

When selecting a screw air compressor, first determine the required working pressure on the gas side, add 1-2 bar of reserve, and then choose

The pressure of the air compressor, which takes into account the pressure loss along the pipeline from the compressor installation location to the actual gas consumption point, based on the distance...

Consider pressure allowances within the range of 1-2 bars. Of course, the size of the pipeline and the number of bends also affect pressure loss.

The greater the pipe diameter and the fewer the bend points, the smaller the pressure loss; conversely, the greater the pressure loss.

Therefore, when the distance between the screw air compressor and the various gas-consuming pipeline ends is too far, it is appropriate to enlarge the diameter of the main pipeline. If environmental conditions

If the installation requirements of the air compressor are met and the operating conditions allow, it can be installed locally at the point of gas use.

(3) Volumetric Flow Selection:

When selecting the volumetric flow of an air compressor, it is first necessary to understand the volumetric flow of all gas-consuming equipment, and then multiply the total flow by 1.2.

1. (i.e., with an additional 20% allowance); 2. New projects can be selected based on flow values provided by the design institute; 3. To the gas equipment suppliers, ...

Select the volumetric flow parameters of gas-consuming equipment; ④ For the reform of air compressor stations, refer to the original parameter values combined with the actual gas consumption situation.

Proper selection is beneficial to both the user and the air compressor equipment; selecting one that is too large is wasteful, while selecting one that is too small may cause the air compressor to operate inefficiently.

Drawbacks such as being in a loading state, insufficient gas supply, or inability to build pressure.

(3) The relationship among power, working pressure, and volumetric flow rate changes when the speed varies, assuming the power remains constant.

And work pressure also changes accordingly; for example: a 22KW air compressor, during manufacturing, determines the working pressure to be 7bar, according to the compressor...

The main engine calculates the speed based on the technical curve, with an exhaust volume of 3.8m³/min; when the working pressure is set at 8bar, the speed must be reduced.

Otherwise, the electric motor will be overloaded; at this point, the exhaust volume is 3.6m³/min; because, as the speed decreases, so does the exhaust volume accordingly.

Analogous.

The selection of power is based on meeting the working pressure and volume flow requirements, with the power supply capacity being sufficient to accommodate the usage power of the matched drive motor.
