Ultra High Pressure Hydraulic/Piston/Diaphragm Hydrogen Compressor For Hydrogen Refueling Station


Product Description


Diaphragm Hydrogen Compressor :

The diaphragm compressor is driven by an electric motor, which rotates the crankshaft through a pulley. The reciprocating linear motion of the piston in the cylinder is achieved through a connecting rod, pushing the hydraulic fluid and causing the diaphragm to vibrate back and forth. Controlled by the intake and exhaust valves, each vibration of the diaphragm completes 1 intake and exhaust cycle.


During the operation of the diaphragm compressor, a small amount of hydraulic fluid in the cylinder leaks into the oil tank through the gap between the piston ring and the cylinder wall, as well as the groove. To compensate for this oil loss and ensure that the diaphragm tightly contacts the cylinder head surface at the end of the compressor stroke to discharge the compressed medium, the oil pump injects oil into the cylinder during the suction process of the diaphragm compressor. The amount of oil injected is slightly more than the leakage amount, and the excess oil flows back to the crankcase through a pressure control valve at the end of the compressor stroke.


Due to the complete separation of the cylinder and the hydraulic chamber by the diaphragm, the compressed medium does not come into contact with the hydraulic fluid, thereby avoiding contamination of the oil and ensuring the purity of the compressed medium.The cylinder, consisting of a cylinder head surface and the diaphragm, forms a closed cavity, thereby providing excellent sealing.


The diaphragm compressor is a special type of reciprocating compressor with high compression ratio, good sealing performance, and resistance to contamination from lubricating oil and other CHINAMFG impurities. It is suitable for compressing high-purity, rare and valuable, flammable and explosive, toxic and harmful, corrosive, and high-pressure gases.

Piston Hydrogen Compressor :

A piston hydrogen compressor is a type of compressor specifically designed for compressing hydrogen gas. It utilizes a piston-cylinder arrangement to increase the pressure of the hydrogen gas to the desired level.


The compressor consists of an electric motor that drives the piston through a crankshaft. As the motor rotates, the piston moves back and forth inside the cylinder, creating a reciprocating motion. This motion compresses the hydrogen gas, reducing its volume and increasing its pressure.


To ensure efficient compression and minimize leakage, the piston and cylinder are carefully designed with tight tolerances and high-quality sealing materials. The compressor may also incorporate valves to control the flow of hydrogen gas during the compression process.


Piston hydrogen compressors are commonly used in various applications that require the compression of hydrogen gas. This includes hydrogen fueling stations for refueling hydrogen-powered vehicles, hydrogen storage and distribution systems, industrial processes that use hydrogen, and research facilities working with hydrogen gas.

Hydraulic Hydrogen Compressor :

A hydraulic hydrogen compressor is a type of compressor specifically designed for compressing hydrogen gas using hydraulic power. It utilizes a hydraulic system to generate the necessary force for compressing hydrogen to higher pressures.


The compressor consists of an electric motor that powers a hydraulic pump. The hydraulic pump generates high-pressure hydraulic fluid that is then used to actuate a piston or a diaphragm. The piston or diaphragm, driven by the hydraulic pressure, compresses the hydrogen gas within a cylinder.


The advantage of a hydraulic hydrogen compressor is its ability to provide high compression ratios and operate at higher pressures efficiently. The hydraulic system allows for precise control of the compression process, enabling smooth and consistent compression of hydrogen gas.


Hydraulic hydrogen compressors are commonly used in various applications that require the compression of hydrogen gas. This includes hydrogen fueling stations, hydrogen storage systems, hydrogen production facilities, and industrial processes that utilize hydrogen.


It’s worth noting that safety considerations are crucial when working with hydrogen gas, and hydraulic hydrogen compressors must meet stringent safety standards. This includes proper ventilation, explosion-proof design, and adherence to strict handling procedures to ensure the safe and reliable operation of the compressor.

How Does a Gas Air Compressor Work?

A gas air compressor works by utilizing a gas engine to power a compressor pump, which draws in air and compresses it to a higher pressure. The compressed air can then be used for various applications. Here’s a detailed explanation of how a gas air compressor operates:

1. Gas Engine:

A gas air compressor is equipped with a gas engine as its power source. The gas engine is typically fueled by gasoline, diesel, natural gas, or propane. When the engine is started, the fuel is combusted within the engine’s cylinders, generating mechanical energy in the form of rotational motion.

2. Compressor Pump:

The gas engine drives the compressor pump through a mechanical linkage, such as a belt or direct coupling. The compressor pump is responsible for drawing in atmospheric air and compressing it to a higher pressure. There are different types of compressor pumps used in gas air compressors, including reciprocating, rotary screw, or centrifugal, each with its own operating principles.

3. Intake Stroke:

In a reciprocating compressor pump, the intake stroke begins when the piston moves downward within the cylinder. This creates a vacuum, causing the inlet valve to open and atmospheric air to be drawn into the cylinder. In rotary screw or centrifugal compressors, air is continuously drawn in through the intake port as the compressor operates.

4. Compression Stroke:

During the compression stroke in a reciprocating compressor, the piston moves upward, reducing the volume within the cylinder. This compression action causes the air to be compressed and its pressure to increase. In rotary screw compressors, two interlocking screws rotate, trapping and compressing the air between them. In centrifugal compressors, air is accelerated and compressed by high-speed rotating impellers.

5. Discharge Stroke:

Once the air is compressed, the discharge stroke begins in reciprocating compressors. The piston moves upward, further reducing the volume and forcing the compressed air out of the cylinder through the discharge valve. In rotary screw compressors, the compressed air is discharged through an outlet port as the interlocking screws continue to rotate. In centrifugal compressors, the high-pressure air is discharged from the impeller into the surrounding volute casing.

6. Pressure Regulation:

Gas air compressors often include pressure regulation mechanisms to control the output pressure of the compressed air. This can be achieved through pressure switches, regulators, or control systems that adjust the compressor’s operation based on the desired pressure setting. These mechanisms help maintain a consistent and controlled supply of compressed air for the specific application requirements.

7. Storage and Application:

The compressed air produced by the gas air compressor is typically stored in a receiver tank or used directly for applications. The receiver tank helps stabilize the pressure and provides a reservoir of compressed air for immediate use. From the receiver tank, the compressed air can be distributed through pipelines to pneumatic tools, machinery, or other devices that require the compressed air for operation.

Overall, a gas air compressor operates by using a gas engine to power a compressor pump, which draws in air and compresses it to a higher pressure. The compressed air is then regulated and used for various applications, providing a reliable source of power for pneumatic tools, machinery, and other equipment.
