The diaphragm liquefied gas tank is primarily composed of a motor, base, crankcase, crank and connecting rod mechanism, cylinder components, oil and gas pipelines, electrical control system, and some accessories. It increases gas pressure through single or multi-stage compression, meeting the customer's requirements for pressure, flow rate, and temperature parameters. The motor drives the crank, connecting rod, and piston to propel hydraulic oil, which in turn drives the diaphragm, compressing the medium through the diaphragm's vibration. The diaphragm press is a special volume liquefied gas storage tank, with its working cylinder divided into two sections by a diaphragm. The top of the diaphragm is called the gas chamber, and the bottom is the oil chamber. During operation, the piston moves upwards to drive the hydraulic oil, which then drives the diaphragm to expel the compressed medium outside the diaphragm chamber. The diaphragm liquefied gas tank compresses the gas through the deformation of the diaphragm. As the diaphragm moves, it must closely fit the cylinder head diaphragm chamber surface and have a smaller gap with the cylinder body diaphragm chamber surface. Through theoretical analysis and scientific selection of the diaphragm chamber curve radius, maximum deflection, and deflection index, a larger volume is ensured, allowing the diaphragm to work under approximately equal strength.

Liquid gas storage tanks offer the following advantages and features:

1) The complete machine structure is reasonably designed, ensuring smooth and reliable operation with minimal vibration and noise, and ease of operation and maintenance. 2) Cylinder components feature a structure without an oiling disk, reducing assembly complexity; fewer sealing surfaces; and an alarm for compressed medium leakage, enhancing the overall reliability of the machine. 3) The new membrane cavity curve improves the volumetric efficiency of the liquefied gas storage tank, and extends the lifespan of the vulnerable components like the membrane and gas valves. 4) The built-in oil pump station provides stable pressure, clean quality, and fully cooled lubricating oil for the liquefied gas storage tank and cylinder operation, also addressing the issue of oil leakage from external storage tanks. 5) A highly automated control system ensures the safe operation of the equipment. 6) The entire equipment is mounted on a skid base for easy transportation, installation, and management.
