Interpretation of energy-saving drive principle

<

1, Frequency energy saving:


In order to ensure the reliability of production, a variety of production machinery in the design and distribution of power-driven, have left some margin. Motor can not run at full load, in addition to meet the power drive requirements, the extra torque increases the active power consumption, resulting in a waste of energy, the high pressure can reduce the motor speed, so that at constant pressure Save electricity.


When the motor speed changes from N1 to N2, its motor shaft power (P) changes as follows:

P2 / P1 = (N2 / N1) 3, we can see the lower the motor speed can be cubic energy-saving effect.

2, dynamically adjust energy saving:

Quickly adapt to load changes, supply maximum efficiency voltage. Inverter software has 5000 times / sec measurement and control output function, always keep the motor output high efficiency operation.

3, through the frequency of its own V / F power saving:

V / F curve can be automatically adjusted while ensuring the motor output torque. Reduce the motor output torque, reduce the input current, to achieve energy-saving state.

4, Frequency conversion comes with soft start Energy saving:

When the motor starts at full pressure, due to the starting torque of the motor needs to absorb 7 times the rated current of the motor from the power grid, and the large starting current is a waste of power, the voltage fluctuation of the power grid is also greatly damaged, an increase of line loss and variable damage. With soft start, the starting current can be from 0 - motor rated current, reducing the impact of starting current on the grid, saving electricity, but also reduce the inertia of the start of the device of large inertia speed impact, extending the life of the device.

5, improve power factor energy saving:

Motor from the stator winding and rotor winding through the role of electromagnetic torque. Winding due to its inductive effect. In terms of the power grid, the impedance characteristic is inductive, and the motor absorbs a large amount of reactive power during operation, resulting in a very low power factor.


Semi-automatic Saw Blade Pipe Cutting Machine

1. Gearbox:

The gearbox is made of casting, so it is very solid. At the same time, it is formed by the horizontal machining center for one-time processing and forming, that accumulated tolerance is small. The core component gear of the gearbox are imported from Taiwan, which is using advanced grinding and vacuum heat treatment technology, with high precision and long service life. In the use process, the noise of the machine head is small, the transmission efficiency is ensured, and the service life is long.

2. A self-lubricating bearing:

It is added at the movable joint between the head and the connecting seat, which can lubricate the connecting shaft in order to prevent the direct friction causing abrasion, so it helps to improve the working life, and accuracy that reduce the vibration of Saw Blade.

3. Regulating valve:

Regulating valve: the control valve imported from Taiwan is adopted, with high machining accuracy, stable flow control and even cutting speed. Fast return speed, improve work efficiency.
