Design characteristics and working principle of diaphragm coupling

Design features of diaphragm coupling:

1, membrane disc coupling, its flexible parts are made of high strength stainless steel, light weight, high strength, good toughness, good corrosion resistance, long life, easy to replace.

2, the structural design and processing accuracy of the membrane disc coupling to ensure that the coupling has a good dynamic balance characteristics, in the process of storage, transportation and installation should be careful to ensure that the dynamic balance characteristics are not damaged.

3, all series of couplings in the middle part of the membrane plate is a whole disassembly, the factory has done a good dynamic balance, not allowed to disassembly outside the factory.

4, according to the specific design and working conditions of the coupling, our company can choose to carry out the dynamic balance of the coupling according to the company's specifications or the corresponding procedures of API671 standard. Factory coupling has been tested for dynamic balance, be sure to align the dynamic balance marking when installing.

5. The membrane plate part of the membrane plate coupling is very thin. Attention should be paid to protection during transportation, installation and use to avoid bumping or scratching.

Working principle of diaphragm disc coupling:

The transmission of torque is from the main (original) motor through the mounting plate and connecting bolt to the membrane plate, on the membrane plate from the rim through the profile to the hub, the middle shaft, and then from the middle shaft to another membrane plate, and then through the profile connecting bolt to the test installation plate from the motor and the driven machine. The fairing plays the role of airflow rectification, and plays the role of protecting the profile of the membrane disk in the single membrane disk structure. It also has the function of containing and protecting the middle shaft from flying out when the membrane disk is damaged. The key component of the diaphragm plate coupling is the two-section "diaphragm plate", and the torque is transmitted through the diaphragm plate with special curved surface.
