Transformation of speed hydraulic coupling

Transformation of R18K.500M speed hydraulic coupling

Transformation method 1: direct coupling, frequency conversion speed regulation, external lubricating oil station;

Transformation mode two: change gear box, pre pump to transform and configure new speed motor;

Transformation mode three: retaining the coupling function, external oil station to restore the oil supply system;

The reform contents include: the field surveying and mapping before the project transformation, the reform scheme design, the implementation of the overall project transformation, and the commissioning and operation after the transformation.

Coupler performance

1, it has the capability of slowing down impact and isolating torsional vibration. It can make the motor start with a delay time, slow acceleration, and reduce the impact between parts caused by sudden start.

2, with the starting performance of the motor with light load due to coupling of the pump wheel torque and speed is proportional to the square, so when the moment of starting the pump wheel due to low speed and torque effect, similar to the pump wheel motor with no-load starting, so short starting time, small starting current, stable starting, especially suitable for heavy load starting with large inertia.

3, with overload protection performance: because no mechanical coupling is directly connected, when the external load exceeds a certain limit, the pump wheel torque will no longer increase, the motor rotation as usual, output slow down until the stop, power from the power draw into heat warms up until the fusible plug coupler, liquid injection, and the input and output is cut off the protection, motor, machine can not be damaged, thereby reducing the machine failure rate, maintenance costs and downtime, prolong the service life of motor bearing working machine.

4, with power-saving performance: because the coupler can effectively solve the motor starting and the "big horse car" phenomenon, compared with the rigid transmission can reduce at least a motor frame size, and can reduce the starting current and duration, reduce the impact on the grid energy saving rate of 10 - 20%, especially in the high starting heavy load inertia is more significant. The characteristics of the torque limiting coupling: there are no mechanical grinding Sassafras except bearing and oil seal. The service life is long, the failure rate is low, and no special maintenance is needed.
