What are the advantages and characteristics of the diaphragm compressor?

The diaphragm compressor has the following advantages and characteristics：

一、Advantage

1.Good sealing: the diaphragm will completely isolate the gas from the power part, effectively prevent gas leakage, ensure the purity of compressed gas, so that it is especially suitable for compression of high purity, rare, valuable, flammable and explosive, toxic and harmful and corrosive gas, to avoid the harm caused by gas leakage to the environment and human body.

2.Large compression ratio: the ratio of the cylinder working volume surface area to the cylinder volume of the diaphragm compressor is much larger than that of the reciprocating piston compressor. The compression of gas is close to the isothermal process, and the pressure ratio of each stage can be as high as 25, which can compress the gas to a higher pressure to meet the demand of high pressure gas in different industrial fields.

3.Oil-free pollution: due to the gas and lubricating oil completely isolated, compression process will not produce any pollution, avoid the oil lubrication piston compressor finished gas high oil content, without regular replacement filter and add special compressor oil, reduce the operating cost, also ensure the cleanliness of the compressed gas, suitable for gas compression sensitive to oil, such as food, medicine, electronic materials and other industries.

4.Stable operation: the diaphragm structure, almost no friction in the process of operation, less moving parts, to reduce the wear and friction fault, stable and reliable operation, minimal noise, not only improve the service life of the equipment, also provides a good guarantee for production and working environment, reduce the noise pollution of the surrounding environment.

5.Simple maintenance: structure is relatively simple, mainly composed of motor, base, crankcase, crankshaft connecting rod movement mechanism, cylinder components, oil and gas pipeline, electronic control system and some accessories, parts, maintenance is more convenient, only need regular inspection and maintenance, such as check the integrity of the diaphragm, the aging of seals, etc., can ensure the normal operation of equipment, reduce the maintenance cost of equipment.

6.Strong self-priming ability: can operate under lower suction pressure, with strong self-priming ability, without external auxiliary equipment, can independently complete the gas inhalation and compression process, improve the use convenience and flexibility of the equipment.

7.High safety: there is strict sealing between working area, drive device and leakage monitoring system, which can avoid the risk of dangerous material leakage during operation, and ensure the safety of operators and equipment even when compression of dangerous gases such as toxic, flammable and explosive.

二、Characteristic

1.Various structure forms: according to the structure form, it can be divided into six forms: z, v, d, l, w, and hexagonal type, and the appropriate structure forms can be selected according to different use scenarios and requirements.

2.Rich diaphragm material: diaphragm material has metal diaphragm (including black metal, nonferrous metal) and non-metal diaphragm two, metal diaphragm high strength, corrosion resistance, suitable for high pressure, strong corrosive gas compression; non-metal diaphragm has good flexibility and corrosion resistance, suitable for some special gas compression.

3.Extensive application fields: due to its above advantages, diaphragm compressor has been widely used in hydrogen energy application, nuclear energy, food, medicine, petrochemical industry, electronic materials and national defense and many other fields, is an important gas compression equipment.

4.Stable pressure output: the working principle of the diaphragm compressor enables it to stably output the pressure, ensure the pressure accuracy and stability of the compressed gas, and meet the requirements of the process with high gas pressure requirements, such as the reaction gas compression in chemical production, gas filling in food packaging, etc.

5.Adapt to small exhaust high pressure conditions: generally suitable for small exhaust but need high pressure scene, for some special small flow, high pressure gas compression requirements, such as high purity gas preparation in the laboratory, hydrogen pressurization in small hydrogenation station, has unique advantages.
