Development Trend of Flange Coupling in my country

Introduce:

The flange coupling is a high-performance coupling product specially developed for high-speed, high-torque, and high-speed machinery. The torque control range of the flange coupling is wide and the control precision is high. The torque is directly proportional to the excitation current in a wide range, which can improve and simplify the control of the transmitted torque, and can be used as a linear adjustment element. It has constant torque, and its static torque is the same as that of torque. The torque that can be transmitted under the condition that has nothing to do with the slip, no shock, vibration, no noise, and balanced operation, is very suitable for occasions with high operating frequency.

Application standards for flange couplings:

1. Couplings should comply with API 671 standard. The grade, type and installation method of the coupling shall be agreed upon by the buyer and the seller of the compressor and the driver;

2. For the flange coupling, the manufacturer should give the allowable value of the displacement of the diaphragm shaft;

3. According to the requirements of the user or the seller, the connection between the coupling and the shaft should be able to be used continuously at 175% of the expected torque and 115% of the expected transmission torque at all operating speeds;

4. The design of the flange coupling should allow it to be used under the conditions of shaft displacement, axial misalignment and non-parallelism of 125%;

5. Coupling parts and assemblies shall be subject to dynamic balance tests before being installed on the machine shaft.

Summarize:

A large-scale transmission mechanical equipment needs to use a coupling, and the coupling plays a very important role. In China, the coupling product of the transmission equipment occupies the first place in the world, but the structure of the coupling product is still somewhat different from that of the developed industry. After the development of production technology to the advanced level, the development of new materials has gradually entered the sight of workers in the field of welding. At present, welding materials are changing from ferrous metals to non-ferrous metals, from metallic materials to non-metallic materials, and from structural materials to functional materials. , in the conversion from multi-dimensional materials to low tensile materials, from single materials to composite materials, in order to solve the problem between high performance and weldability of materials, new materials need to be incorporated into the production of couplings to improve the flange coupling product quality and welding efficiency, thereby improving the overall development level of the transmission field. Provided by the machinery factory. In order to meet the needs of different customers, our factory undertakes the design, replacement and manufacture of other non-standard couplings and imported couplings. In this regard, the factory has accumulated rich experience. Our goal is to become a merchant with excellent product quality, fast delivery time and excellent service.
