How to Choose an Oil-Free Gas Compressor Suitable for Your Operating Conditions

How to Choose an Oil-Free Gas Compressor Suitable for Your Operating Conditions

A. 1. First, determine your working gas medium. If it's a single component, please inform us of the gas purity and whether it contains water vapor and hydrogen sulfide. Their presence will severely impact the compressor's stable operation. If it's a mixed gas, please tell us the composition of each gas.

2. Second, determine the inlet pressure. Inlet pressure is usually expressed in kilograms, Pascals, or Megapascals. Please specify whether it's gauge pressure or absolute pressure. Absolute pressure = gauge pressure + 1 Pa. If the inlet pressure is a range, please also indicate the fluctuation range.

3. Third, determine the operating pressure. Considering pipeline pressure drop, the compressor's discharge pressure is generally slightly higher than your required operating pressure. For example, if your operating pressure is 100 kg/m³, the compressor discharge pressure should be 105 kg/m³.

4. Fourth, determine the required compressor flow rate. This is generally determined based on the operating flow rate and is usually indicated using CFH, NM³/HR, or SM³/HR. Note that some customers prefer to use M³/HR. To distinguish them, NM3 and M3 are different. M3 is the flow rate under operating conditions, while NM3 is the compressor flow rate under standard conditions. Unless otherwise specified, we use NM3 flow rates.

4. Does the compressor operate indoors or outdoors? What is the ambient temperature? Is there cooling water

5. What is the local three-phase voltage frequency? For example, 380V 50HZ/3 phase, or 460V 60HZ/3 phase, etc.

6. What is the compressor's load? Is it planned to operate for 8 hours a day, 15 hours a day, or 24 hours a day

7. Are there any other special requirements, such as whether it is PLC controlled, or whether various compressor signals need to be transmitted remotely to the central control room? Our standard control method is traditional switch instrument control, without PLC control.
