Product Description

Reciprotating Completely Oil-Free Hydrogen Diaphragm Compressor
                                              ( Blue Font To View Hyperlink)
Our company specialize in making various kinds of compressors, such as:,, Air compressors,,,,etc. All products can be customized according to your parameters and other requirements.
Process principle
Hydrogen Diaphragm compressor according to the needs of the user, choose the right type of compressor to meet the needs of the user. The diaphragm of the metal diaphragm compressor completely separates the gas from the hydraulic oil system to ensure the purity of the gas and no pollution to the gas. At the same time, advanced manufacturing technology and accurate membrane cavity design technology are adopted to ensure the service life of the diaphragm compressor diaphragm. No pollution: the metal diaphragm group completely separates the process gas from the hydraulic oil and lubricating oil parts to ensure the gas purity.
Main Structure
Diaphragm compressor structure is mainly composed of motor, base, crankcase, crankshaft linkage mechanism, cylinder components, crankshaft connecting rod, piston, oil and gas pipeline, electric control system and some accessories.
Gas Media type
Our compressors can compress ammonia, propylene, nitrogen, oxygen, helium, hydrogen, hydrogen chloride, argon, hydrogen chloride, hydrogen sulfide, hydrogen bromide, ethylene, acetylene, etc.(Nitrogen diaphragm compressor,bottle filling compressor,oxygen diaphragm compressor)
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.
The compressor is consists of a three pieces of diaphragms. The diaphragm is clamped along the surrounding area by the hydraulic oil side and the process gas side of the process. The diaphragm is driven by the hydraulic driver in the film head to achieve the compression and transportation of the gas. The main body of the diaphragm compressor consists of two systems: the hydraulic oil system and the gas compression system, and the metal membrane separates these two systems.
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 stroke.

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.
