Application of V&T TS syychronous servo drive for large hydraulic equipment

Shenzhen V&T Technologies Co., Ltd

Large forging equipment, large-scale moulding machine equipment are known collectively as large hydraulic equipment. The equipment system use a large hydraulic station system which needs a lot of hydraulic power systems, in which the asynchronous motor is up to hundreds of kilowatts and system pressure isabove 25 MPa. Therefore, the power consumption is very alarming to cause large power waste.

In order to save energy, our company V&T and a hydraulic equipment manufacturer from Xiamen completed matching for a large hydraulic device with 2500 tons pressure to export to German this May. The device has 320 pressure sensors to realize full closed loop control. By joint use of synchronous servo motor and TS hybrid servo drive with torque-power compound control, it successfully increase the oil discharge from a 55kw asynchronous motor 320L/min to a 53kw asynchronous motor, greatly reducing the power of matching motor required. The original device was 4 sets of 55 asynchronous motor 4 and 1 set of 22kw asynchronous motor. Now it is configured for 2 sets of 53kw permanent magnet synchronous motor and 1 set of 10.3KW synchronous motor, which enormously saves energy.

   

After the detection of German experts, we got a lot of good results as follows

1.Product repeat accuracy is 100%,

2.During the five-minute holding pressure, the fluctuation is only 0.075MPA at 25MPa.

3.The actual working power rating is only 23.43KW during 25MPa holding presure.

4.The pressure speed 860mm/s, return speed is 568mm/s.

5.The running is very smooth that the sloshing is less than 0.5mm when German experts put the horizontal gyro testing instrument on the equipment moving mode.

6.The equipment save energy 53.86% more than the original asynchronous motor power, which got unanimous praise from both German experts and the equipment manufacturer.

Besides this project, we also offered solutions to more famous manufactuers.
