• What is a centrifugal pump coupling?

  The centrifugal pump coupling is used to connect the shafts in different mechanisms, mainly through rotation, so as to achieve the transmission torque.Under the action of high-speed power, the centrifugal pump coupling has the functions of buffering and damping, and the centrifugal pump coupling has a better service life and work efficiency guarantee.

• How to reduce the loosening of coupling bolts?

  The coupling is to firmly connect the driving shaft and the driven shaft of the equipment and rotate together. If the coupling bolts are loose or slip out, it will affect the normal operation of the mechanical equipment. What impact will the loose coupling bolts cause? ?

• What are the stability of the diaphragm coupling

  Diaphragm couplings are also called elastic laminated couplings or laminated flexible couplings, which transform the diaphragm couplings into sodium bentonite. Fine planing guarantees the level 3 accuracy and surface roughness of the cast iron scribing platform In one process, the cast iron scribing platform with accuracy above level 2 must be manually scraped to ensure the geometric accuracy of the plate. The qualified cast iron scribing platform should be protected from the influence of heat sources and corrosion by acid and alkali.High-precision cast iron...

• What are the accessories and installation and disassembly steps of the diaphragm coupling

  The bolt of the diaphragm coupling is one of the important components. The correct installation of the diaphragm coupling bolt directly affects the performance life and performance of the diaphragm coupling, otherwise it will cause waste of manpower and accessories.Therefore, the correct installation of the bolt direction is a key part, and you must remember not to install it backwards or drop any small parts including spring washers, so that the bolt assembly can exert its excellent performance and will not make the coupling...

• What maintenance principles need to be mastered for the lubrication of diaphragm couplings

  During the effective life of the diaphragm coupling, the wedge-shaped clearance surfaces that are inclined to each other need to be maintained, lubricated, and fed from the large port to the small port.The two surfaces have sufficient relative movement speed, the fluid has sufficient viscosity, and sufficient oil is required.

• What causes the coupling failure

  The characteristics of the sprocket coupling: The chain coupling has a simple structure, is easy to assemble and disassemble, does not need to move the connected two shafts during disassembly, is compact in size, light in weight, has a certain compensation ability, and does not require high installation accuracy. Reliable work, longer life, lower cost and other advantages.

• What problems are prone to occur when the coupling is installed

  The axis of the coupling is skewed and the coupling can’t advance: In order to prevent such incidents, in addition to the alignment of the axis, the orientation of the coupling hole and the shaft, and the orientation of the striker, it is also necessary to be careful. The direction of the hitting point must be selected, and the second hit must be light. After entering a certain distance (about 1/3), the force can be used to slam.

• What factors will affect the life of the coupling diaphragm

  The main influencing factors that determine the structural life are stress amplitude and average stress. The most influential is the numerical value of the stress amplitude. The stress amplitude refers to the bending stress amplitude caused by the angular displacement of the dynamic stress.

• How to improve the life of the coupling

  The coupling should be lubricated with lithium soap-based grease containing pressure additives.Examples include but are not limited to ESSO Beacon EP and Mobil Temp 78.There are many alternatives to choose from, because almost every grease manufacturer makes greases for this and similar applications.

• Precautions for the use of couplings

  The coupling is not allowed to have more than the specified shaft center line skew and radial displacement, so as not to affect its transmission performance.
