They are key components of various pumps, reaction synthesis kettles, turbine compressors, submersible motors and other equipment. When producing mechanical seals, manufacturers today use pressing devices to press the modules of mechanical seals to ensure that the module parts of the mechanical seals are tightly pressed together to improve the reliability of the connection between the two. Seals assembled using pressing devices can improve their own sealing effects.

The hole can be used to clamp seals of different specifications, and the applicability is strong. The utility model is provided with a support assembly, and the threaded rods on both sides of the base move downward and cooperate with the buffer block to support the base, so that the pulley at the bottom of the base does not contact the placement surface, effectively avoiding the impact force generated when the device is in use to cause damage to the pulley, and plays a certain protective role on the pulley, solving the problem of the existing clamping mechanism that the seal cannot be clamped and positioned when the device is in use, and at the same time, when the pressure plate of the original device moves down for clamping, the impact force easily causes damage to the pulley of the pulley group.
