Application scope of hydraulic coupling energy saving transformation project

Because the Hydraulic Coupling solves the difficult problem of motor starting, so the motor start with heavy load approximate load, and low starting current, short starting time, small impact on the grid, the startup process of low power consumption; the startup time is longer, the number of starts more frequently, using more energy saving hydraulic coupling transmission.

Reducing motor capacity and energy saving

Because the hydraulic coupler can solve the problem of difficult mechanical startup of large inertia, plus overload protection, isolation impact and vibration torsion, when designing and selecting, there is no need to increase the selection margin of motor greatly, usually press the type selection.

The hydraulic coupling drive and rigid transmission ratio can at least reduce one motor seat number, reduce installed capacity 15% ~ 25%.d, and reduce the motor seat number, and its energy saving effect is obvious.

The function factor improves the power factor. It can reduce the power capacity and conductor cross section, reduce voltage loss and voltage fluctuation on the line, and improve the function of power supply and transportation.

Reduce the motor no-load loss total loss of good data show that the decline of a motor seat, the total consumption dropped by an average of 4.8%.

The normal running current of the motor reduces the same power, and the small size motor is lower than the running current of the specification motor.

Energy saving of overload protection

The running current is steady and the current is impacted with large current without overload, and the average running current is reduced.

The selection of motor under overload load without considering the safety margin, reducing the installed capacity

The protection motor and working machine are not damaged when overloading, reducing the failure rate of the equipment and prolonging the service life.

Harmonization of multi motive balance driving energy saving

The sequential start - up of energy saving motor greatly reduces the starting current and the impact on the power grid in order to reduce the power consumption at start - up. The data show that when three Motors Co - drive a working machine, the power saving of the motor is 50% compared to the synchronous motor.

Due to the balance and vibration of each motor load, the balance load can make the motor run smoothly, so that the total driving power is reduced and the electric energy is saved.

Reducing shock and isolating energy and torsional energy

The hydraulic coupling separates the strong impact load and vibration of the working machine. It is the smooth operation of the motor, avoids the current impact of the peak load, and is beneficial to the electricity saving.

When the hydraulic coupling is added, the larger working condition is not selected, the motor can be selected according to the requirements of normal operation, the power margin of the motor is greatly reduced, and the electric energy is saved.

Ensure that the motor is damaged by the impact load and prolongs the service life.

The important application range of the coupler

1. belt conveyor, scraper conveyor, bucket promotion machine, bridge type, tower crane and other lifting machine.

2. mill, crusher, crusher, sand mixer and filter and other smelting ore machines.

3. centrifugal meter, stirring machine, cement conveyor, and large inertia facilities such as fan, water gun and so on.

4. in the power, iron, iron, ore, smelting and other industries has played a great role in energy conservation, emission reduction and environmental protection.

The above is an important field and scope for the application of the coupler.
