Energy-saving Solutions for Enterprise
1、Program Overview
◆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: 65w adapter and 90w laptop power adapter What is the difference?
- 65W and 90W is mainly based on your laptop power configuration, the general integrated graphics with 65W, discrete graphics because of the need for additional power supply, so the general need 90W, of course, there are some low-power CPU, such as 25WCPU , 35W, 45W difference, these are the beginning of the manufacturer according to the notebook's power consumption count a maximum power, and then give your laptop with adapter 90W adapter can replace 65W, as long as the interface is the same, but 65W instead of 90W sometimes there may be insufficient power lead to automatic shutdown. In general, the greater the number of watts, the larger the head, because the adapter is actually a coil will be 220V into 19V, according to the power to determine the head, the larger the watt, the same 19V, then the output current will be greater
- Q: What is the difference between variable frequency motor and variable speed motor?
- Give you a formula, you can understand their speed control principle: N (speed) = 60f (frequency) divided by P (magnetic pole logarithm) According to the formula, when you want to change the motor speed, there are only two ways to change The number of pole pairs and the frequency of the power supply. Speed ??motor is variable pole speed, that is, in this motor has 2 to 3 sets of windings, by changing the winding connection, to change the motor pole to change the rotation speed.
- Q: ABB frequency converter and the difference between domestic frequency converter
- Optical microscope mainly by the eyepiece, objective lens, stage and mirror composition.
- Q: What are the AC motor speed control methods? What are the characteristics of each
- 1, the frequency converter: smooth, according to the need to adjust the speed, is the future direction of the development of AC motor; (FM) 2, star, triangular connection conversion, generally in the larger motor start star start, triangular operation, Starting current. (Magnetic pole pairs) 3, there is a two-speed, three-speed motor, an increase of the winding, the main change in the stator winding connection to change the speed. (Change the number of pole pairs) The speed of change has two factors: magnetic pole logarithm, frequency
- Q: Fuji inverter motor set the number of poles will not have any effect?
- The number of motor poles set incorrectly, self-learning when the motor parameters are not correct, not the correct parameters of the motor. Inverter control speed is not accurate, and the motor will heat, can not work properly.
- Q: 11kw 6-pole motor can be used to adjust the inverter to 1800RPM?
- Frequency conversion frequency f to 90Hz can. 1800 = 60x90 / 3,3 that is 3 pole, is 6 pole. Regardless of load.
- Q: Three sets of batteries (540V) DC power supply U / f inverter.
- It is estimated that the battery should be string - and - series connection method, and then rectifier part of the converter (which may also be caused by the switch) is actually a series of diodes in series, positive and negative after the reverse is actually the battery is Negative shorts, resulting in burning, as to burn only one of the group of a few cells, it should be string - and - string and that group, because the parallel to bear it double voltage.
- 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.
- Q: 90KW inverter start 90KW, 4-pole motor and 6-pole motor j What is the difference? The inverter can be used for it?
- The number of poles of the motor and the inverter is not very different, the difference is the motor speed is different
- Q: First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
- And the inverter is connected to the positive and negative bk-dk electrical Han Han device,
