Energy-saving Solutions for Enterprise
◆Saving energy achieves 10% -70%
◆The enterprises do not need to pay for expense of equipment manufacture and installation.
◆Enterprises only need to pay the saving electricity expense to our company according to the actual quantity of energy saving after the equipments put into operation.
◆According thousands of the projects’ implementation experiences, such projects recover the investments in three or four years. (Equipment service life is 15 years)。
◆Our company will no longer charge the saving electricity expense after recovering the investment.
The significance of the program:
1）、Concentrate on solving problems of energy conservation, make enterprises’ energy-saving work reach new level and take their social responsibility。
2）、Avoid the enterprises reactive power fine of low power factor caused by electric energy using (according to Ministry of Electric Power and Water Resources, State Price Control Bureau establish the " measures of power factor adjustment expense ").
3）、Avoid the high-energy consumption enterprises are implemented differential prices because of the changes of national power regulation.
4）、For the standard-conforming large-scale (saved energy equal 10 thousand tons standard coal or more) energy-saving technological transformation projects, China will reward the enterprises for energy saving which based on the "Financial Incentives Interim Measure for Energy-saving Technological Transformations" established by Ministry of Finance, the National Development and Reform Commission.( Amount of 200 yuan / ton of standard coal).
5）、Equipments recovery period is generally 3-4 years, each period payment equal to the amount of current energy-saving benefits, and equipments service life are 15 years, so enterprises will gain huge energy-saving benefits.

- Q:Speed regulation method of three - phase asynchronous motor
- This is the two-speed motor 1 will be the UI VI WI connected to the third phase of the remaining joint empty at this time for the four 2 U2 V2 W2 connected to the other three junctions at this time for the two levels This is the angle - there are many binary speed
In addition there are three-speed motor in this no longer introduced
The number of variable pole pairs can be varied, but the more variable the number of logarithmic materials
Like a two-speed motor with a set of windings
Three-speed motor has two sets of windings
So the current single-board frequency conversion speed up
- Q:Why the notebook power adapter can not be universal
- First, the interface is different
Most laptop power adapter brands have different interfaces, which means that other brands of power adapters can not be plugged into your laptop for power supply. The interface is relatively safe, because at least you will not plug in the current or voltage does not meet the power adapter to the laptop power supply, which led to computer hardware damage.
- Q:The laptop power adapter is hot
- Notebook power adapter in the power after the use of hot is a normal phenomenon, do not worry, no danger, it will not explode. The length of this time does not matter, in the use of one or two hours will become very hot, but will always keep this temperature. And the notebook's power adapter shell are high temperature, will not burn.
Notebook power adapter in addition to hot, you may hear the sound, the sound is not, very small. This sound is not a big problem, it is the power adapter power after the power filter sound, so plug in the plug after. Any power adapter basically has a sound. You can listen carefully, the surrounding environment is particularly quiet when you can hear.
Power adapter is a transformer, inside the transformer coil in the AC will produce Zizi sound. Some power adapter use a long time will have this sound, but no big problem, you can continue to use. As long as the sound is not high outrageous do not control.
Laptop power adapter hot and sound basic are considered normal, unless the temperature is too high or even damage to the shell or the sound is very obvious, this is a problem. The general does not affect the use of the adapter bad to buy a can. Notebooks have to protect the isolation circuit, do not worry about damage to the notebook.
- Q:First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
- In short, then connected to the bk-dk electrical appliances, is a resistor for the discharge effect
- Q:The notebook power adapter flashes
- 1: Check the socket with a multimeter is normal, the supply voltage is 220V. If the utility voltage is not normal, it is recommended to replace the use of environmental testing.
2: Check with the multimeter whether the output voltage and current of the power adapter match the label. If the gap is very large, and the mains voltage is normal, you can determine the power adapter failure, need to replace the laptop power adapter.
3: If the above check is normal, remove the laptop battery, do not external adapter. Press and hold the notebook power button 5 seconds to repeat 3 times. After releasing the notebook residual charge, insert the power adapter separately, power on the test.
4: If the fault persists, check the notebook's power connector, whether the exception. Such as loose or the appearance of damage and so on.
5: the above checks are normal, basically can be a preliminary judgment is the notebook motherboard failure. Recommended repair service station.
- Q:Variable frequency conversion frequency difference characteristics based on,
- Frequency conversion is better, you can smoothly change the synchronous speed.
Change the difference is relatively poor, also known as "energy consumption slip" speed. Synchronous speed unchanged, the slip rate has changed, so the speed changed.
- Q:How to choose the inverter
- Look at the motor seat size is 7.5kw it, this model of the inverter manufacturers a lot of production, and are built-in brake unit, so in the function which are the same
It is important that the inverter life, stability, price comprehensive consideration
Mitsubishi, Panasonic, LG, Emerson, Yaskawa, Siemens and so on
- Q:Delta VFD-A frequency converter motor number of poles set
- Variable frequency
Drive, VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment. The inverter is mainly rectified (AC variable DC), filter
Wave, inverter (DC variable AC), the braking unit, the drive unit, the detection unit micro-processing unit and so on. The inverter is used to adjust the voltage and frequency of the output power by breaking the internal IGBT.
- Q:If it is 8-pole variable frequency motor, enter the motor nameplate parameters in the inverter input for the 4 pole can?
- Motor brand above all, the general number of wrong is the inverter shows the speed is not right, for the speed control requirements are not high places will not be a problem, you can use
- Q:How to make the motor speed (control speed), can not use frequency
- In general, the torque generated by the motor is reduced with decreasing frequency (decrease in speed), and the reduced actual data is given in some frequency converter manuals. By using the flux vector control of the inverter, will improve the motor at low speed torque, even in the low speed area motor can also output enough torque. When the frequency converter to speed up to 60Hz frequency, the motor output torque will reduce the normal motor is designed to 50Hz (60Hz) voltage, the rated torque is given in this voltage range. So the rated frequency under the speed is called constant torque speed, the inverter output frequency is greater than 50Hz frequency, the motor torque to be inversely proportional to the frequency of the relationship between the decline. When the motor is running at a frequency greater than 60 Hz, the magnitude of the motor load must be taken into account to prevent the motor output torque from being insufficient. For example, when the torque generated by the motor at 100 Hz is about to be reduced to about 50 Hz, the torque is generated. So the rated frequency above the speed is called constant power speed.
