GD diaphragm compressor V structure

Core structural advantage: V-shaped design, efficient and stable performance cornerstone

The GD diaphragm compressor adopts a classic V-shaped cylinder arrangement layout, with the centerlines of the two columns of cylinders distributed at a specific angle. This structural design brings multiple core advantages and can highly adapt to the installation and operation needs of various industrial sites around the world:

-Excellent power balance: The V-shaped layout allows the inertia force generated by the reciprocating motion of the cylinder to cancel each other out, greatly reducing the vibration and noise during equipment operation, effectively improving the overall stability of the machine, and extending the service life of key components.

-Compact and compact structure: Compared to traditional inline or other structures, the V-shaped arrangement significantly reduces the equipment footprint, making it easy to install and deploy in scenarios with limited factory space, while also reserving sufficient operational space for subsequent maintenance.

-Higher heat dissipation efficiency: The V-shaped structure increases the ratio of cylinder surface area to volume, coupled with optimized airway design, which can quickly dissipate the heat generated during the compression process, avoiding excessive temperature rise that affects operating efficiency and gas quality.

-Easy assembly and maintenance: The cylinder components are designed without oil distribution plates, reducing the number of sealing surfaces and lowering the difficulty of assembly processes; The layout of key components is reasonable, and daily maintenance and replacement of vulnerable parts do not require dismantling the entire machine, significantly improving maintenance efficiency.

Working principle: Diaphragm isolation, the core guarantee of clean compression

GD diaphragm compressor adopts the core working mechanism of "hydraulic drive+diaphragm isolation", and cooperates with V-shaped two-stage cylinder to achieve efficient gas compression, ensuring clean and pollution-free gas throughout the process:

1. Power transmission: The GD diaphragm compressor is powered by an electric motor, which drives the crankshaft to rotate through a V-belt. The crankshaft then drives the main and auxiliary connecting rods, which in turn drive the first and second stage oil cylinder pistons arranged in a V-shape to perform reciprocating motion.

2. Diaphragm drive: The reciprocating motion of the cylinder piston drives the hydraulic oil, causing periodic changes in the oil pressure inside the cylinder; The diaphragm is clamped between the cylinder head and the oil distribution plate, generating elastic vibration under the pressure difference between oil and gas and its own elasticity, periodically changing the volume of the gas compression chamber.

3. Compression cycle: Under the precise control of the intake and exhaust valves, a four stage cycle of "suction compression exhaust expansion" is completed: in the suction stage, the diaphragm moves downward to make the chamber pressure lower than the intake pressure, and the suction valve opens for intake; During the compression stage, the diaphragm moves upwards to compress the gas until the pressure in the chamber reaches the opening pressure of the exhaust valve; During the exhaust phase, high-pressure gas is discharged through the exhaust valve and enters the next stage of compression or storage; During the expansion phase, residual gas expands and releases pressure, preparing for the next round of inhalation.

4. Cleanliness guarantee: The diaphragm completely isolates the air chamber from the oil cylinder, and the compressed medium only comes into contact with the metal diaphragm. No lubricant needs to be added to the cylinder, which avoids gas contamination by oil stains from the source and can ensure gas purity up to 99.9999%.
