GD diaphragm compressor D structure

Core structure and working principle

The GD diaphragm compressor D structure adopts a symmetrical D-type structure layout, with core components including a motor, integrated pry mount base, crankcase, crankshaft connecting rod mechanism, D-type cylinder assembly, metal diaphragm group, hydraulic system, cooling system, and intelligent electronic control system. The core working principle of the GD diaphragm compressor D structure is based on volume change to achieve gas compression: the crankshaft connecting rod mechanism is driven by a motor, which drives the piston to make reciprocating motion in the hydraulic chamber, causing pressure changes in the hydraulic oil, and then pushing the metal diaphragm to synchronously reciprocate and deform in the diaphragm chamber. The volume of the membrane cavity undergoes periodic contraction and expansion, completing the process of gas suction, compression, and discharge.

Key structural advantages: The metal diaphragm assembly completely isolates the process gas from the hydraulic oil system, fundamentally eliminating the pollution of gas by lubricating oil; The D-shaped symmetrical structure design makes the whole machine run more smoothly and with less vibration, while optimizing the cylinder heat dissipation conditions, achieving a compression process close to isothermal, effectively improving compression efficiency and component service life.

Core advantages of the product

1. Ultimate sealing, high-purity cleanliness

The GD diaphragm compressor D structure adopts a fully sealed diaphragm structure design, which completely isolates the gas channel from the outside without any leakage points. It can handle flammable, explosive, toxic, harmful, highly corrosive, and high-purity rare gases such as hydrogen, ammonia, oxygen, argon, helium, hydrogen chloride, hydrogen sulfide, etc. During the compression process of the GD diaphragm compressor D structure, the gas does not come into contact with any lubricating oil or solid impurities, ensuring a purity of over 99.999% for the output gas, and even meeting the ultra-high purity gas processing requirements of 99.9999%. It is fully suitable for high-end foreign trade scenarios such as high-purity gas preparation in the global electronic semiconductor industry and sterile gas transportation in the medical and pharmaceutical industry. The GD diaphragm compressor D structure has undergone strict helium leak detection and performance testing, complying with international dangerous goods transportation and industrial safety regulations, providing a solid guarantee for the safety production of overseas customers.

2. D-type structure optimization, stable and reliable operation

The exclusive D-type structural layout achieves the balance of the center of gravity of the entire machine, coupled with low-speed design, greatly reducing vibration and noise during operation. The vibration intensity of the body is ≤ 8mm/s, the cylinder head is ≤ 10mm/s, and the sound power level of the noise (outside 1m of the unit) is not greater than 88dB (A), which meets international industrial noise and vibration standards and is suitable for the environmental requirements of different overseas factory areas. The cylinder components adopt a symmetrical design, combined with an integrated water jacket cooling structure on the middle body, cylinder body, and cylinder head, which has excellent heat dissipation efficiency and effectively controls the gas temperature during compression (the exhaust temperature of each stage is not greater than 180 ℃), avoiding changes in gas properties or component losses caused by high temperatures. At the same time, the D-type structure is easy to maintain and operate, with the weight of core maintenance components controlled between 60-70kg. A maintenance space of at least 1m can be reserved around the equipment to complete routine maintenance, greatly reducing the difficulty and cost of operation and maintenance for overseas customers; The replacement cycle of key vulnerable parts in the GD diaphragm compressor D structure is clear (diaphragm ≥ 3000h, air valve ≥ 6000h), and long-term stable overseas spare parts supply services can be provided.

3. High voltage and high efficiency, widely adaptable

The optimized membrane cavity curve design and efficient gas valve group configuration enable the GD diaphragm compressor D structure to have the core characteristics of high compression ratio and high exhaust pressure. The maximum exhaust pressure can be customized to 100MPa according to demand, and the maximum displacement of a single unit can reach 750Nm ³/h, which can accurately match the process parameter requirements of different countries and regions. The GD diaphragm compressor D structure fully complies with core technical standards such as JB/T 6905-2019, and can also meet the relevant certification specifications of mainstream foreign trade markets such as the European Union, Japan, and South Korea (such as explosion-proof level not lower than dIICT4), adapting to diverse global application scenarios. In addition, the GD diaphragm compressor D structure adopts a modular pry design, which is compact and easy to transport. It can be flexibly adjusted according to the installation conditions of the export destination, and is equipped with a multilingual intelligent electronic control system and a fully English operation manual, providing convenient use and operation experience for overseas customers.
