Diaphragm compressors are essential pieces of equipment in hydrogenation stations because they can handle a wide range of gas pressures with high efficiency and reliability. In this article, we will discuss the most commonly used models and pressures of diaphragm compressors in hydrogenation stations.
Firstly, let's understand what a diaphragm compressor is. A diaphragm compressor is a positive displacement compressor that uses a flexible diaphragm to compress gases. The diaphragm separates the compression chamber from the drive mechanism and the crankcase, ensuring that the gas being compressed is not contaminated with oil or other lubricants used in the drive mechanism. Diaphragm compressors can handle a wide range of pressures, from low vacuum to high pressure.
There are two main types of diaphragm compressors: single-stage and multistage. Single-stage diaphragm compressors compress the gas in one stroke, whereas multistage compressors use several stages to compress the gas to the desired pressure. Multistage diaphragm compressors are more commonly used in hydrogenation stations because they can achieve much higher pressures efficiently.
The pressures required in hydrogenation stations depend on the specific process, but typically vary between 100 and 400 bar. For example, a hydrogen refueling station for fuel cell vehicles requires a compression pressure of around 700 bar to store hydrogen in high-pressure storage tanks. The pressure range for hydrogenation stations can be achieved using either single or multistage diaphragm compressors, but multistage compressors are more commonly used because they can achieve higher pressures with greater efficiency.
In addition to the type of compressor, there are several things to consider when selecting a diaphragm compressor for use in a hydrogenation station. For example, the materials used in the construction of the compressor should be resistant to the corrosive effects of hydrogen gas. Additionally, the compressor should be designed to minimize leaks and ensure safety in a hazardous environment.
In conclusion, diaphragm compressors are commonly used in hydrogenation stations because of their ability to handle a wide range of gas pressures with high efficiency and reliability. Multistage diaphragm compressors are more commonly used in hydrogenation stations because they can achieve much higher pressures efficiently. When selecting a diaphragm compressor for use in a hydrogenation station, factors like the materials used in construction and safety in a hazardous environment must be considered.
