Product Features
Key Product Advantages
High-Purity, Contamination-Free Gas Compression
A diaphragm-based structure completely isolates the gas side from the hydraulic drive side, preventing lubricating oil, piston seal wear particles, and external impurities from entering the gas stream. Gas purity levels of up to 99.999% can be achieved, meeting the stringent requirements of applications such as electronic specialty gases, laboratory analysis, high-purity hydrogen, and other ultra-high-purity gas processes.
Superior Sealing and Low Leakage Risk
The diaphragm design eliminates the dynamic piston rod seals found in traditional reciprocating compressors; combined with specialized diaphragm and sealing configurations, it effectively prevents the leakage of hazardous gases. Diaphragm compressors offer a more reliable sealing solution for demanding operating conditions involving hydrogen sulfide, hydrogen, oxygen, and flammable or explosive media.
Wide Pressure Range and High-Pressure Capability
The equipment supports single-stage or multi-stage compression configurations tailored to specific process requirements, ensuring stable gas delivery from low inlet pressures to high outlet pressures. Its high compression ratio makes it suitable for a wide range of applications, including gas boosting, cylinder filling, recovery, circulation, and high-pressure supply.
Structural and Technical Features
Integrated Compressor Body
The compressor body features an integrated structural design, which reduces the number of sealing interfaces and minimizes potential leakage points. This design also enhances the machining and assembly precision of critical components, resulting in more stable and reliable equipment operation.
Crankcase-Integrated Oil Charging Pump
The oil charging pump is integrated within the crankcase, providing a stable and continuous supply of hydraulic oil to the cylinder. This design not only helps maintain smooth hydraulic system operation but also reduces the risk of oil leaks associated with external piping connections, resulting in a more compact overall structure.
Floating Connection and Self-Centering Design
The piston rod and crosshead utilize a floating connection with self-centering capabilities. This configuration improves the load distribution and alignment of moving parts, enhances operational stability, and helps extend the service life of critical moving components.
Imported Hydraulic Sealing System
The piston seal employs hydraulic sealing components imported from Germany, enhancing the sealing reliability and operational stability of the oil circuit system. A stable hydraulic system ensures a uniform and reliable driving force for the reciprocating motion of the diaphragm.
Uniform Hydraulic Oil Distribution Structure
The high-pressure cylinder utilizes an oil distribution structure that eliminates the need for distribution plates or screens, allowing for more uniform hydraulic oil distribution within the cylinder. Compared to traditional annular-groove distribution designs, this approach simplifies assembly and reduces the stringent requirements for sealing surface machining and assembly conditions.
Seamless Diaphragm Design
The diaphragm features a seamless (non-perforated) design, which enhances interchangeability and ease of installation. This structure minimizes stress concentrations often associated with traditional openings, thereby supporting the long-term, stable operation of the diaphragm.
