  • Operation problems of diaphragm couplingRelease Date: 2021-06-03

    Due to various reasons, the center of mass or inertial principal axis of the diaphragm coupling does not coincide with the axis of rotation, and the phenomenon of unbalanced centrifugal inertial force, centrifugal inertial couple force and dynamic deflection (vibration shape) will occur during operation, which is called the phenomenon of rotor Imbalance.

  • Installation matters and principles of use of diaphragm couplingRelease Date: 2021-06-03

    Because hot-loading is performed under high temperature and stress, it is necessary to have sufficient estimates of possible problems and try to avoid them in advance. If it happens, you should also panic on the spot and take timely measures to deal with it.

  • The damage of drum gear coupling and the requirement of drum curveRelease Date: 2021-06-03

    The main reason is that the vibration damper of the main engine has sunk, which makes the shafting of the coupling appear asymmetry, thereby increasing the additional torque, which causes the coupling to heat up and break during use. accident.

  • Causes of fatigue failure of diaphragm couplingRelease Date: 2021-06-03

    ​For the specific conditions of failure, damage and deformation of the diaphragm coupling of the front pump, the main reasons that may cause the fatigue failure of the diaphragm coupling are summarized by analyzing the cold alignment data during the infrastructure period and the vibration data of the pump operation.

  • The use of diaphragm coupling and screw installation methodRelease Date: 2021-06-03

    During the service life of the diaphragm coupling, it is necessary to maintain the wedge-shaped clearance surfaces that are inclined to each other, add lubricating oil, and enter the small opening from the large port.The two surfaces have sufficient relative movement speed, the fluid has sufficient viscosity, and sufficient oil is required.

  • The characteristics and force calculation of diaphragm couplingRelease Date: 2021-06-03

    ​Diaphragm coupling has the characteristics of small size, large carrying capacity, light weight, mechanical strength, good transmission speed and transmission accuracy, convenient assembly and disassembly, no lubrication, good service life, and no noise.

  • Coupling connection and drum gear coupling installationRelease Date: 2021-06-03

    ​Couplings and clutches are devices used to connect two shafts so that they can rotate together and transmit torque.

  • The composition of the diaphragm coupling and the cause of damageRelease Date: 2021-06-03

    Diaphragm coupling is mainly composed of stainless steel sheet metal (steel sheet), half coupling, intermediate sleeve, compression element, bolt, lock nut, limit washer, etc.
