Liaoning Jinding Technology Development Co., Ltd. has manufactured industrial gas compression equipment since 1995. Based in Dandong, Liaoning, China, Jinding supplies diaphragm compressors in multiple series for industrial gas compression, alongside piston compressors and complete acetylene production equipment.
A diaphragm compressor uses a flexible metal diaphragm to separate the process gas from the hydraulic drive system. The diaphragm moves under hydraulic pressure to compress the gas within the compression chamber, limiting direct contact between the process gas and the drive-side hydraulic fluid.
This separation is particularly relevant to applications involving hydrogen, acetylene and other gases that require careful control of contamination and leakage. Diaphragm material, gas compatibility, sealing design and operating pressure must be evaluated according to the specific application.
Jinding's diaphragm compressor range includes the following series. Model selection depends on the required compression performance and the conditions of the intended process.
Key parameters include gas composition, inlet and discharge pressure, required flow rate, compression ratio, cooling requirements and operating cycle. Providing these details, together with any available process specifications or technical drawings, helps establish the requirements for model selection and engineering evaluation.
Jinding's manufacturing facilities include a 6,000 m² machining workshop, more than 100 sets of mechanical processing and testing equipment, and two independently developed automated production lines. The company reports an annual production capacity of more than 500 diaphragm compressors.
Machining, assembly and testing support the production of equipment for different industrial gas applications. Equipment specifications and inspection requirements can be coordinated according to the technical requirements of each project.
Diaphragm compressors are used in applications where gas separation, pressure requirements and process compatibility are important considerations. Jinding's equipment serves sectors including hydrogen energy, petrochemicals, fine chemicals, electronics and other industrial gas processes.
For equipment selection, installation, commissioning, maintenance and spare parts support, Jinding works with customers to address project-specific requirements. To request an initial technical assessment, provide the gas type, inlet and discharge pressures, required flow rate and intended operating conditions.
To request an initial technical assessment, provide the gas type, inlet and discharge pressures, required flow rate and intended operating conditions. Jinding's engineering team can then review the requirements and propose a suitable diaphragm compressor configuration.
