What is a hydrogen compressor?
The hydrogen compressor is a device designed specifically to compress hydrogen gas for storage. The low hydrogen density makes it a demanding medium for storage in that it requires extremely high tank pressures between £ 5,000 and £ 10,000 per square inch (dogs). Commercial hydrogen compressors are generally reciprocal types, with the most common controlled piston/metal membranes and rotor variants. Although these designs are essentially positive pumps to shift, there are several other hydrogen compressors such as hydrides and electrochemical types that have no moving parts at all. However, most hydrogen compressor structures are characterized by their high output pressure abilities with average delivery pressure exceeding 15,000. All these applications require hydrogen to be stored under high pressure, usually between 5,000 and 10,000 dogs. This is partly due to low hydrogen gas density at atmospheric pressure. At these low pressures has a gram of hydrogen gas inMem almost 3 gallons (11 liters), which requires the gas to be compressed intensely if it is to be stored. Hydrogen compressor units are used to compress gas for huge pressures, often exceeding 15,000 dogs to be stored in usable quantities.
Several different types of compressor are used to compress hydrogen; More common are types of pistons or metal membranes. These compressors of reciproc with positive displacement machines that operate by capturing a small amount of gas into an enclosed space, reduce the volume by shifting, and then release the compressed gas into the retention or storage tank. This cycle is repeated until the tank reaches its maximum capacity. One type of piston compressor to achieve this goal uses three pistons; Motine piston powered by compressed air or hydraulic fluid and pair of compressor pistons that compress gas. The compressor pistons are attached to the motifMu piston through a few connecting bars that provide the necessary connected movement.
Another common type of hydrogen compressor is the compressor of the controlled rotor. This type of hydrogen compressor uses a rotor laval mounted on an eccentric shaft that rotates in a specially designed chamber. This type of compressor, as in principle as a rotary internal combustion engines, relies on the gas displacement in the lobe chamber to achieve its compression values. There are several types of low volume compressors without moving parts, such as a hydride compressor used to produce a small amount of pressure hydrogen gas for laboratory use. These compressors use the thermal reaction of heated hydride to form a small amount of vacuum hydrogen.
most industrial hydrogen storage equipment uses to pressure their hydrogen supply by positive shift. In some cases, these compressors are able to produce outputs greater than 15,000 psi and some giveUp to 30,000 dogs. These values mean that the average tank pressure of 10,000 dogs used mostly devices for research of green cars can be quickly and efficiently achieved.
