Product Description

Xuzhou Huayan Gas Equipment Co.,Ltd, exporting , piston compressor, , gas cylinder and nitrogen generators with good quality and low price.

Diaphragm compressor is a reciprocating compressor that compresses and transports gas by the reciprocating motion of the diaphragm in the cylinder. The diaphragm is clamped by two restraint plates along the periphery and forms a cylinder. The diaphragm is driven by hydraulic force to move back and forth in the cylinder, so as to achieve the compression and transportation of gas. With a large compression ratio, wide pressure range, good sealing characteristics. Since its gas chamber does not need any lubrication, thus ensuring the purity of compressed gas, especially suitable for flammable, explosive, toxic and harmful, high-purity gas compression, transportation and bottling.

Advantages
No leakage: the compressor membrane head is sealed by static "O" ring. The O "ring is made of elastic material, with long service life and no dynamic seal to ensure no leakage during gas compression.
Corrosion resistance: the compressor membrane head can be made of 316L stainless steel, the diaphragm is made of 301 stainless steel.
Small tightening torque: "O" ring seal, can reduce flange bolt tightening torque, reduce shutdown maintenance time.
Basically, the structure of the diaphragm compressor is divided into two parts: the hydraulic framework and the pneumatic force framework. During the compression process, there are two steps: the suction stroke and the delivery strok

We offer a wide variety and types of compressors. You can install these in many different scenarios. It is possible to install the compressors in hydrogen houses between and electrolyser and a storage system, in businesses to support their needs such as ice cream companies for hydrogenation, at farmers where they use it to produce ammonia or as a fuel at the back of a wind farm or solar farm, and refineries to pressurise the hydrogen before it is being used to clean up the gas or oil. There are also many applications for our H2 compressors.For instance, you can also use the compressor in green hydrogen transport applications, energy storage solutions, grid balancing, food processing, and power station cooling. We pride ourselves at ensuring that as many applications of our compressor units use renewable electricity to pressurise the hydrogenWe can pressurise hydrogen into different types of storage systems at 200 bar, 350 bar (5000 psi), 450 bar, 500 bar, 700 bar (10,000 psi), 900 bar (13,000 psi).

Diaphragm compressors are usually driven by an electric motor and driven by a belt (many current designs use direct-drive couplings due to associated safety requirements). The belt drives the flywheel mounted on the crankshaft to rotate, and the crank drives the connecting rod into reciprocating motion. The connecting rod and the crosshead are connected by a crosshead pin, and the crosshead reciprocates on the settlement segment.

 

 

The hydraulic piston (piston rod) is mounted to the crosshead. The piston is sealed by piston rings and reciprocates in a hydraulic cylinder. Each movement of the piston generates a fixed volume of lubricating oil, thereby driving the diaphragm to reciprocate. The lubricating oil acts on the diaphragm, so it is actually the diaphragm compressed gas.

 

 

The main functions of hydraulic oil in diaphragm compressors are: lubricating moving parts; compressing gas; cooling. The circulation of lubricating oil starts from the crankcase, where the crankcase seat oil sump. The lubricating oil enters the inlet filter, and the lubricating oil is usually cooled by a water-cooled cooler. The lubricating oil then enters the mechanical oil pump and is filtered through the filter. Then the lubricating oil is divided into two ways, one way to lubricate the bearings, connecting rod small heads, etc., and the other way into the compensation pump, which is used to push the diaphragm movement.
