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.

Enhance competitiveness through implementing energy conservation, improving energy-saving efficiency, reducing energy costs and enhancing the quality of environment, establish green corporate image and enhance market competiveness.

Q:How does the variable frequency motor output torque at very low frequencies?
50hz the following frequency, u constant, current and frequency is proportional to the frequency down the output current is also down, and torque and current is proportional to the natural torque is small
Q:The laptop power adapter is hot
My point of view: First: your laptop power supply in a small ventilation environment, resulting in poor heat dissipation, Second: the life of the power supply is 3-5 years, the gradual oxidation of electronic components and some of the aging components, resulting in no load and load a lot of power, Third: the battery close to each run, and then connected to the power, the power to the battery charger and notebook power supply, so the pressure is not hot strange.
Q:If it is 8-pole variable frequency motor, enter the motor nameplate parameters in the inverter input for the 4 pole can?
According to the number of revolutions N = 60 * f (frequency) / p (pole pairs) can calculate the motor is a few poles. If the motor is 8 pole is not recommended in the inverter set to 4. will certainly affect the control accuracy.
Q:Is the laptop power adapter long-haul?
Can, rarely say there is a power adapter without power and failure, my notebook 5 years, never pull the power adapter plug, never power, there is no problem. Of course, save electricity and care from the point of view, it is recommended to pull the best, because the adapter is still in the working state.
Q:What is the number of parameters of the motor frequency of the Siemens inverter?
Siemens inverter motor pole number parameter code is r0313 motor pole pairs. Note that the number of pole pairs.
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:Computer frequency changer to do cd frequency changer how points positive and negative
. In this circuit, the total capacitance is 6500 microfarads, the voltage is doubled.
Q:What is the difference between AC and DC frequency converters?
Advantages and disadvantages: Advantages: inverter air conditioner with variable frequency power supply, inverter compressor, electronic expansion valve and microcomputer technology, the organic combination of air conditioning to further improve the performance, the use of room temperature fluctuations, better comfort, the better Power supply voltage fluctuation is not sensitive, the compressor starts, the general non-stop, cooling capacity in the range of 35% to 117% change, to avoid the frequent open air-conditioning, to extend the life of the compressor, while efficient, Features. Disadvantages: the price is more expensive, compared with ordinary air conditioning, about 1/3 to 1/4 of the price, at the same time, because the inverter air conditioner control system and frequency conversion system is more complex, higher requirements for components, compared to ordinary air conditioning , Inverter air conditioner failure rate is high, and, due to the use of frequency conversion technology, at the same time, will produce harmonic pollution. What is DC inverter air conditioner? DC inverter air conditioner is relative to the AC inverter air conditioner, in fact, its name is not correct, because the DC and no frequency, it is by changing the DC voltage to adjust the compressor speed, thus changing the air conditioning cooling capacity, It can only be said to be a DC variable speed air conditioning, not strictly in the sense of inverter air conditioner.
Q:How do I select a drive? Which brand is better
?11, the inverter drives the synchronous motor, compared with the power frequency power regulator, reduce the output capacity of 10% to 20%, the inverter's continuous output current is greater than the synchronous motor rated current and synchronous pull the current value of the unit value product. ????12, for the compressor, vibration and other torque fluctuations in the load and the hydraulic pump and other peak load case, if the motor in accordance with the rated current or power value of the inverter, then there may be due to peak current over-current protection Action phenomenon. Therefore, you should understand the frequency of the operation of the situation, select the maximum current than the maximum current output of the inverter. When the inverter drives the submersible pump motor, the rated current is greater than the rated current of the submersible pump motor because the rated current of the submersible pump motor is greater than the rated current of the normal motor. ????13, when the inverter control Roots blower, because of its large starting current, so select the inverter must pay attention to whether the capacity of the inverter is large enough. ????14, select the inverter, be sure to pay attention to whether the protection level with the scene to match. Otherwise the scene of dust, water vapor will affect the long-term operation of the inverter. ????15, single-phase motor is not suitable for inverter drive. Recommended Ampang letter converter, domestic brand, quality and stability, first-class service, trustworthy!
Q:Why the notebook power adapter can not be universal
Second, the voltage is different Different brands of laptop power adapter voltage is not the same, for example: under normal circumstances IBM is 16V, Dell is 20V, Hp is 18.5V, Sony is 19.5V and so on. Thus, even if the power adapter interface is the same, can not use different brands of laptop power adapter for power supply.
