Bolts are important components of double diaphragm coupling, the installation of bolts directly affect the performance and life of the coupling and the safety of the work process. If installed properly, it will cause a certain amount of human waste and wear parts, to the enterprise to increase the burden and affect the benefits. So the correct installation technique is the key.

    When installing a double diaphragm coupling, do not drop any one of the parts, including the spring washer, and remember that it can not be installed. So as to ensure that the bolt components to play excellent performance, will not make the other parts of the coupling damage.

    Botou City Friends of Sheng Co., Ltd. to provide various types of diaphragm coupling diaphragm, the diaphragm used by the import of stainless steel materials, after the Friends of the coupling factory patented process - vacuum heat treatment and cryogenic treatment, both to ensure that The strength of the material also ensures the toughness of the material.

    Double diaphragm coupling correct installation of the bolt method: the bolt from the flange hole into the outside, and then penetrate into the diaphragm hole (note the direction of the diaphragm, the diaphragm is composed of a number of individual pieces of rivets and rivets, The rivet gasket should be in contact with the buffer sleeve, otherwise it will affect the life of the rivet group), and then from the outside of the flange outside the hole into the sleeve sleeve, elastic washers, screw on the nut tightening Do not turn, because the bolt and flange with the segment surface is very important to pass the torque with the section, the surface integrity of a direct impact on the use of performance.

    Double diaphragm coupling bolt with the flange and the hole with the gap, generally according to the bolt diameter of 0.20mm ~ 0.30mm This match section to play a very critical role in the transmission torque, if the gap must be replaced. Buffer sleeve and diaphragm rivet hole and bolt diameter gap of 0.5mm ~ 0.7mm, play a role in pressing and positioning the diaphragm. If the direction of the bolt is easy to cause the bolt skew, and the diaphragm will be distorted. Therefore, in the installation of bolts must pay attention to the direction of the bolt, do not arbitrarily install the direction of the bolt, otherwise it will cause the diaphragm twisted, long-term operation will make the diaphragm and bolt with the surface, half shaft small hole damage.
