What is the effect of the coupler accessories in the coupler operation? The following is a brief introduction to you.
When the input shaft of a motor driven rotary pump wheel coupling through the working liquid pump wheel working chamber by centrifugal force by the pump wheel entrance small radius are accelerated by pressure into the larger radius of the pump impeller outlet, at the same time, the momentum generated liquid increment, i.e. pump wheel input mechanical energy into the liquid kinetic energy.
When the working fluid carrying liquid kinetic energy is running from the pump outlet to the opposite turbine, the liquid flow will move centripetal along the flow path formed by the turbine blade, and at the same time, the liquid kinetic energy can be released to transform mechanical energy, drive the turbine and rotate the load with load. As a result, when the input and output are not directly mechanically connected, the liquid kinetic energy is flexible.
The hydraulic couplings can be driven in both positive and negative directions. When the installation is completed, the first trial run must check whether the coupling meets the required direction of rotation, and it should not be rapidly reversed. Install a mesh shield on the coupler. When the motor reaches the rated speed, it must start running from the motive. If the motive is not moved, it must be stopped imtely to check whether the load has the phenomenon of braking.
The coupling is not allowed to leak when running. In continuous operation, the temperature of the working oil does not exceed 90 degrees C. After 3000 hours of operation, the aging of the oil is checked. If the oil is old, the oil should be changed. The wear condition of the elastic disk in the coupling should be checked regularly with the repair period of the machine, and the coaxial accuracy of the motor and work shaft (such as reducer) should be regularly checked and corrected, so as to ensure smooth operation. It is not allowed to dismantle the coupler at will, so as not to destroy the sealing and assembly precision.
The fusible alloy coupling parts fusible plug in a melting point of 120 DEG C, if the failure due to increased oil temperature, make shift molten alloy melting, oil is ejected when troubleshooting, re filling oil. Note, do not use metal plugs instead of moving the fusible plug. Do not start frequently in order to prevent the overheating of working oil. There should be good ventilation conditions to prevent direct sunlight.
