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:30 kW 6 pole frequency motor torque is how much
Look at the motor sample or nameplate, above some Different manufacturers of the motor may be different I have a sample on hand, 90KW, six pole, frame number 315M1, rated current 168A, rated torque 859.4 And then look at your inverter performance and motor performance, and can generally be overloaded to the rated torque of 150%
Q:Notebook plug in the power adapter lights, but can not open the machine
This is a contradictory problem: First, the power adapter lights because the power is good, but does not mean that the computer is good; Second, can not open the machine with the power adapter is lit, it is your computer reasons. Recommendation: Check the computer hardware. Asked: But the battery can be used to start ah answer: Remove the battery plug in the adapter or put the battery installed plug in the adapter, if you can not open the machine, then it is a hardware conflict. The solution to the hardware conflict is that you try another adapter. Asked: the battery removed to die, but as long as there is a battery can answer: it shows that your adapter is bad. Asked: the more magical is plug in the adapter and the battery, the battery will not consume Answer: get you electronic city so that they give you a test. You can say to buy an adapter, and then try, you can use the words to buy, can not use the words and then think of other methods.
Q:90KW inverter start 90KW, 4-pole motor and 6-pole motor j What is the difference? The inverter can be used for it?
Two motors can use the same frequency converter, but the motor nameplate data through the parameters to adjust the input when the inverter should pay attention to some
Q:Is it possible to use a different laptop's power adapter?
See the adapter is suitable for notebook models to use, the following three conditions for reference: 1. The output voltage of the adapter is the same as that of the notebook. 2. Is the adapter's output current consistent with the notebook's requirements? (Or a little bit of the current is also not.) 3. The size of the joint is appropriate. (If the connector is too loose, will be bad, excessive fever.) For DELL and HP / Compaq and other notebook power adapter, will involve a decoding problem. Please pay attention when the pro to buy. It is said that the market is also very popular universal adapter, a friend bought a LVSUN brand universal adapter LS-PAB90-BC10, with eight joints. Adapter has a liquid crystal display, you can automatically switch the voltage, very smart, with more than a year, has also been used
Q:Laptop power adapter (no power supply, but indicator light)
Notebook power adapter can not charge, but the indicator light does not light the common reasons are: 1, the power adapter is broken or the connector is broken. 2, the power adapter output problem, no output or output is too low, can not give the computer charge. 3, the notebook charging interface is broken, not into the electricity charge. 4, the notebook power management circuit out of the fault, resulting in can not charge.
Q:How do I protect the inverter when the three-phase two-pole motor is running?
A: At this time to put the heart in the stomach, wait and see the change, what do not move (to prevent the accident to expand), until the motor stops, and then confirm, what kind of protection: alarm (alarm automatically after the release) or failure , Such as: over-voltage, overload, over-temperature, etc., and then the right medicine; inverter in the run which is not allowed, forced parking stop. Otherwise it will cause serious damage to the inverter.
Q:The inverter control power is also the same, the pole is not the same as the motor 6 or 4 pole can be used?
Can be used, but is being used in the motor replacement, you need to change the frequency conversion.
Q:Inverter principle eff23
The basic principle of the inverter The inverter is a device that converts the power frequency (50Hz or 60Hz) into AC power of various frequencies to realize the variable speed operation of the motor. The control circuit completes the control of the main circuit, and the rectifier circuit converts the alternating current into direct current and DC Circuit rectifier circuit output smooth filter, the inverter circuit will reverse into the DC power.
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:Speed of 3000 r / min three-phase motor how to change its speed
Only the frequency converter to achieve the purpose of speed, because the rated voltage and frequency, the three-phase motor speed is determined by the motor within the pole pairs of pole number, but the frequency down, the speed decreases, plus a frequency converter, Can achieve the purpose of stepless speed regulation. The speed is calculated as: speed = (50 Hz * 60 seconds) / (number of poles / 2), the result is synchronous speed, the general asynchronous motor slightly lower than the synchronous speed. There is a change for the electromagnetic speed of the motor, but also to achieve the purpose of stepless speed regulation. If you have a fixed number of revolutions, you can consider buying a reducer and motor integrated, such as cycloid reducer, can also be installed between the motor and equipment reducer to achieve the purpose of deceleration.
