DIAPHRAGM COMPRESSOR
Ultimate Purity for Critical and Hazardous Applications
Diaphragm compressor is a special structure positive displacement compressor.
The cylinder does not need to be lubricated, the sealing performance is good, the compression medium does not contact any lubricant, and there is no pollution during the compression process, so the compression purity can reach 99.999%. It is widely used in the transportation and pressurization of high-value rare gases and highly corrosive, toxic, harmful, flammable, explosive, and radioactive gases.
Diaphragm compressor cylinder has good heat dissipation, simple structure and high efficiency. Two-stage compression can reach a maximum exhaust pressure of 150MPa. It is widely used in chemical industry, oil refining, electronics, medicine, food and medicine, petrochemical industry, aviation/nuclear power, military equipment, scientific research and testing, etc. The field is widely used.
Key Structural Configurations
Our diaphragm compressors are available in multiple structural configurations to meet diverse industrial requirements. Each design is engineered to optimize performance, safety, and maintenance access for specific applications:
-
V Type Diaphragm Compressor: Engineered for high-pressure applications, the V-type configuration offers exceptional mechanical stability and a compact footprint. Ideal for demanding environments such as military equipment testing and high-end scientific research where space is limited but performance cannot be compromised.
-
Z Type Diaphragm Compressor: This vertical design provides superior alignment of the compression chambers, reducing vibration and wear. Its streamlined layout makes it a preferred choice for pharmaceutical and electronics manufacturing, where ultra-clean and quiet operation is paramount.
-
D Type Diaphragm Compressor: Known for its robust construction and ease of maintenance, the D-type model is widely adopted in the petrochemical and oil refining industries. Its design allows for straightforward access to critical components, minimizing downtime during routine servicing.
-
L Type Diaphragm Compressor: Combining versatility with high efficiency, the L-type compressor excels in handling a wide range of gases with varying chemical properties. It is frequently specified for hazardous gas transportation and nuclear power plant instrumentation systems.
Why Choose Diaphragm Compression Technology?
In industries where air or gas purity is non-negotiable, and where the medium itself poses significant safety risks, conventional compressors fall short. Our diaphragm technology provides the definitive solution by creating a hermetical seal between the drive mechanism and the compressed gas stream.
-
Absolute Oil-Free & Contamination-Free: Since the piston or plunger does not directly contact the cylinder wall, and no lubricating oil is introduced into the compression chamber, the delivered gas maintains pharmaceutical-grade purity.
-
Unparalleled Safety: The complete isolation of the mechanical components from the process gas protects both the equipment and the operators. This makes our compressors the safest available option for handling toxic, explosive, or radioactive materials.
-
Exceptional Durability: The simple yet effective design, combined with excellent heat dissipation characteristics, ensures a long service life even under continuous high-pressure operation.
Frequently Asked Questions (FAQ)
Q: What defines a "special structure positive displacement compressor," and how does it differ from screw or piston compressors?
A: Unlike dynamic compressors (like centrifugal types) or open-contact piston compressors, a diaphragm compressor uses a flexible metal diaphragm to separate the compression chamber from the hydraulic or mechanical drive. The drive moves a fluid (usually hydraulic oil) to flex the diaphragm, creating the compression. This hermetic seal is the defining feature that allows for oil-free and zero-contamination compression.
Q: Can these compressors handle gases other than air?
A: Absolutely. In fact, their primary application is often with specialized gases. Thanks to the hermetic seal, diaphragm compressors are the industry standard for transporting and compressing high-value rare gases (like neon or xenon), corrosive chemicals, and hazardous materials that would destroy or contaminate standard compressors.
Q: What is the maximum pressure capability mentioned in the text?
A: The document specifies that a two-stage compression configuration using this technology can achieve a maximum exhaust pressure of 150 MPa (approximately 21,750 psi). This extreme pressure range makes them indispensable for high-tech and heavy industrial applications.
Q: Are diaphragm compressors difficult to maintain due to their complex design?
A: While they incorporate precision-engineered components, their design is fundamentally simple, consisting primarily of a diaphragm, a headplate, and a hydraulic driver. The separation of the process gas from the lubricant means that the compression chamber itself requires no oil changes or internal cleaning. Maintenance is typically focused on the hydraulic drive system and the periodic inspection/replacement of the diaphragm.
Q: Which industries benefit the most from this level of compression purity and safety?
A: Any industry dealing with sensitive processes or dangerous substances benefits immensely. This includes:
-
Pharmaceutical & Medical: For breathing air systems and sterile gas delivery.
-
Semiconductor & Electronics: For providing ultra-pure nitrogen or inert gases.
-
Petrochemical & Refining: For hydrogen recycling and chloride gas compression.
-
Defense & Nuclear: For powering pneumatic systems and handling radioactive isotopes.
