babjehec specializes in the production of LPG storage tanks
The diaphragm liquefied gas storage tank is primarily composed of an electric motor, base, crankcase, crank and connecting rod motion mechanism, cylinder components, oil and gas pipelines, electrical control system, and some accessories. It increases gas pressure through single or multi-stage compression to meet customers' requirements for pressure, flow rate, temperature, and other process parameters. The electric motor drives the crank, connecting rod, and piston to move hydraulic oil, which in turn drives the diaphragm, compressing the medium through the diaphragm's vibration. The diaphragm press is a special type of volumetric liquefied gas storage tank, with its working cylinder separated into two parts by a diaphragm. The upper part of the diaphragm is called the gas cavity, and the lower part is called the oil cavity. During operation, the piston moves upward to drive the hydraulic oil, which then drives the diaphragm to expel the compressed medium outside the diaphragm cavity. The diaphragm liquefied gas storage tank works by compressing the gas through diaphragm deformation. As the diaphragm moves, it must closely adhere to the cylinder cover diaphragm cavity surface and have a small gap with the cylinder body diaphragm cavity surface. By theoretically analyzing and scientifically selecting the diaphragm cavity curve radius, maximum deflection, and deflection index, a larger volume is ensured, allowing the diaphragm to work under approximately equal strength conditions.
Liquefied gas storage tanks offer the following advantages and features:
1) The complete machine structure is designed rationally, ensuring smooth and reliable operation with minimal vibration and noise, and ease of operation and maintenance. 2) Cylinder components utilize a structure without an oiling dish, reducing assembly complexity and sealing surfaces; an alarm triggers upon compression medium leakage, enhancing the machine's reliability. 3) The new diaphragm cavity curve improves the volumetric efficiency of the liquefied gas storage tank and extends the lifespan of vulnerable parts like diaphragms and gas valves. 4) The built-in oil pump station supplies a pressure-stable, clean, and well-cooled lubricant for the liquefied gas storage tank and cylinder, addressing the issue of oil leakage in the original external storage tank. 5) A highly automated control system ensures the safe operation of the equipment. 6) The entire unit is mounted on a skid base, facilitating transportation, installation, and management of the equipment.

Liquefied Petroleum Gas TankWe offer compressed gas or liquefied gas storage tanks, etc.Liquefied Petroleum Gas (LPG) Storage TankFixed-volume and variable-volume storage tanks, depending on whether the volume changes with the container, with large fixed-volume tanks.Liquefied Petroleum Gas TankSpherical in shape, smaller ones are made cylindrical. The movable volume storage tank, also known as a low-pressure gas storage tank or commonly referred to as a gas holder, can change its geometric volume, is airtight, and prevents gas leakage. It also serves to balance air pressure and regulate the gas supply volume, with the pressure generally not exceeding 60MPa.
Liquefied gas storage tanks undergo stringent quality assessment for the material of pressure components, external dimensions and weld quality, operational quality, installation quality, internal equipment, and safety accessories.
Routine physical and chemical tests for the drum material, such as mechanical properties and chemical composition.
Rigorous X-ray non-destructive testing and magnetic particle inspection are conducted on the welding joints, seams, head ends of the tanks, and the geometric positions of all pressure elements relative to each other. Tests are also performed on the product's sealing, pressure resistance, and any technical indicators that may affect the safe operation of the product.
