There are concerns about the avoidance of dual diaphragm couplings

The key material of the diaphragm coupling is the metal diaphragm, which is generally imported austenitic stainless steel, and there is no difference between domestic and foreign materials; In terms of design and calculation, finite element and optimization technology have been widely adopted, and the product performance of domestic mainstream enterprises has been comparable with foreign brands; Typical diaphragm were given by finite element analysis of stress distribution, optimized diaphragm shapes only retained the torque is the necessary material, and in almost all the excess material, such not only the stress distribution of diaphragm is reasonable, and has a large flexible, which can compensate the big wrong, and to connect additional reaction of equipment.

The application of double diaphragm couplings in industry was developed in the 1960s and 1970s. After the reform and opening up, with the introduction of large sets of industrial equipment, diaphragm coupling gradually understood by the people. Because of the diaphragm coupling has many advantages, it has become a process power equipment, especially large petrochemical process pump, boiler feed pump, blower, compressor unit, etc.

In terms of processing technology, fine punching, laser cutting, various high-precision machining centers have been applied to the production process of diaphragm coupling parts, parts processing accuracy and surface state and foreign products have no big difference. In short, the design performance and processing level of domestic diaphragm coupling has been comparable with foreign enterprises, it is completely able to design and manufacture high performance double diaphragm coupling of various grades to meet the standards.

In the early 1980s, some domestic scientific research institutions began to study the design and application of diaphragm coupling. After more than 20 years of development, its application performance has been developed from small power, low speed pump group to high power, high speed turbine compressor unit. Domestic diaphragm coupling has basically replaced imported products. At the same time, in the original use of tooth coupling in the transformation of the old unit diaphragm coupling is often used, sometimes often have the effect of "resurrection".

However, domestic users often have concerns about the selection of domestic diaphragm coupling, especially for large turbine compressor units. Their main concerns are as follows:

1, worry about the design and manufacture of domestic diaphragm coupling is not up to standard.

2, worry about domestic materials do not pass.

3. Worry about the lack of application performance of domestic diaphragm coupling.

In fact, these fears are now unnecessary. Domestic mainstream enterprises generally start from basic research, master material selection, design and calculation, processing technology, dynamic balance and other key technologies, and have more than 20 years of engineering application experience. Elastic double diaphragm coupling has also accumulated a lot of achievements in the field of high speed and high power.
