Product Description
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.
Key Components of a Compressor
1.Compressor Main Unit
The main unit types of compressors include: diaphragm type, piston type, screw type, and liquid-driven type. The main unit comprises the following components: crankcase, crankshaft, connecting rod, piston, cylinder block, cylinder head, and sealing elements.
2.Piping and Cooling System
Common cooling methods for compressors include water cooling or air cooling. Some piston compressors utilize a hybrid approach with gas air-cooling and partial water cooling for the cylinder head. Cooling systems can be custom-designed and manufactured according to customer requirements.
3.Power Drive
Compressors are predominantly driven by electric motors (over 90% of applications). In scenarios without electrical power, diesel engines or natural gas engines may be employed. Our company offers custom-engineered engine-driven solutions based on customer specifications and machine models.
4.Electrical Control System
The electrical control system is divided into high-voltage and low-voltage sections:
High-voltage section: Refers to power supply systems with voltages of 220V/380V or higher, primarily used for driving high-power equipment such as motors.
Low-voltage section: Includes controllers, instrumentation, and other low-voltage devices, typically operating at safe voltages of 24V or 36V.
5.Oil Pressure System
The lubrication system is critical for stable compressor operation. It not only lubricates moving components and reduces operating temperatures but also ensures discharge pressure stability in diaphragm compressors, where oil pressure directly governs consistent performance.
Application
Food industry, petroleum industry, chemical industry, electronics industry, nuclear power plant, aerospace, medicine, scientific research.
Outlet pressure at 50bar 200 bar, 350 bar (5000 psi), 450 bar, 500 bar, 700 bar (10,000 psi), 900 bar (13,000 psi) and other pressure can be customized .
Nitrogen Diaphragm Compressor
A nitrogen diaphragm compressor is a positive displacement compressor that utilizes metal/non-metal diaphragms to completely isolate the gas from the lubrication system. Through reciprocating motion, it compresses nitrogen (Nitrogen) to achieve high-pressure, high-purity gas delivery. Its core features include oil-free operation and excellent sealing performance, making it particularly suitable for industrial applications with stringent gas purity requirements.
Key Advantages
High-Purity Compression
Oil-free lubrication design prevents nitrogen contamination, delivering purity levels exceeding 99.99%-ideal for electronics and food-grade applications.
High Pressure & Safety Assurance
High-strength diaphragms (e.g., 316L stainless steel, PTFE-coated) withstand pressures up to 30-50MPa, with ATEX/CE explosion-proof certification.
Zero Leakage & Corrosion Resistance
Multi-layer sealing + leakage monitoring system ensures compatibility with high-purity nitrogen and corrosive gas mixtures (e.g., Nitrogen+H2o).
Low Maintenance & Extended Lifespan
Diaphragm service life exceeds 6,000 hours, eliminating frequent oil changes and reducing operational costs by 30%+.
