In the machinery industry, variable speed fluid couplings are widely used, covering boiler feed pumps, delivery pumps, blowers, induced draft fans, crushers, centrifuges, belt conveyors and many other equipment, which can not only save electricity, but also adapt to the needs of mechanical processes. Among them, the YOTc speed-regulating hydraulic coupling, as an outlet-regulated speed-regulating hydraulic coupling, has outstanding performance in improving energy saving in mechanical operation.
I. Working Principle and Speed Regulation Mechanism
The working chamber of the YOTc series variable speed hydrodynamic coupling will be filled with a certain amount of working fluid (generally No. 32 turbine oil), and the active parts of its rotating part are connected to the motor. After the pump wheel obtains mechanical energy from the motor, the working fluid is made to move relative and involved through the blades, which is converted into liquid energy to drive the turbine to rotate, and then connected to the working machine through the output shaft, the liquid energy is converted into mechanical energy, and the energy transfer from the prime mover to the working machine is realized.
The key to its stepless speed regulation is to adjust the opening size of the oil discharge system conduit to change the amount of liquid in the working chamber. When the motor speed remains unchanged, the working machine can be steplessly regulated, thereby flexibly changing the output power to adapt to the energy requirements under different working conditions.
II. The Core Advantages of Helping Mechanical Operation Energy Saving
Significant power saving effect: The working machine can be steplessly regulated, and the output power can be accurately adjusted according to the actual working conditions to avoid energy waste. The power saving rate is 20%~40%, which can save a lot of energy costs for the machine in long-term operation.
Optimize multi-machine drive energy consumption: In the multi-machine drive scenario, power balance and sequential start can be performed to reduce the impact current of the power grid. This not only reduces the load pressure on the power grid, but also avoids the concentrated energy consumption when multiple machines are started at the same time, making energy distribution more reasonable and improving the overall energy utilization efficiency.
Reduce the overall operating cost: Our coupling has a simple and reliable structure, and is cheaper and has less operating costs than variable frequency speed regulation and CST speed regulator. It has no mechanical wear, can work in harsh environments, does not require special maintenance, has a long service life, reduces the additional costs of equipment replacement and maintenance, and achieves energy saving and consumption reduction from the perspective of the entire life cycle.
In summary, the YOTc speed-regulating hydrodynamic coupling, with its unique working principle and excellent characteristics, effectively improves the energy-saving effect through precise speed regulation and optimized power distribution during mechanical operation, and is an ideal choice for the machinery industry to achieve efficient and economical operation.
