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: Laptop power adapter current is not the same alternative?
- because the output power is not enough, will burn. Note the voltage polarity!
- 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: Inverter signal line analog 4-20mA connection positive and negative can be reversed?
- Analog input signal is particularly vulnerable to external interference, so the general use of twisted shield as a signal line; and wiring as short as possible, generally not more than 20 meters; if some use conditions are vulnerable to external serious interference, the analog signal Side need to add a filter capacitor or ferrite core.
- Q: ASUS power adapter Acer can use it
- 3. The size of the joint is appropriate. (If the connector is too loose, will be bad, excessive fever.) If it is for DELL and HP / Compaq and other notebook power adapter, will involve a decoding problem. Please pay attention when the pro to buy. Acer and Asus are not yet available. 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 also automatically switch the voltage, very smart, with more than a year, has also been used.
- Q: Notebook plug in the power adapter lights, but can not open the machine
- 1. Remove the power adapter and battery, the host does not power the case, hold down the boot button does not move, keep the notebook 30 seconds to release the residual static electricity; 2. Connect the power adapter separately to try to power on; 3. Connect the battery separately to try to boot; 4. If conditions permit, you can plug the memory test.
- Q: What is the characteristic of the variable pole speed method?
- Edit this paragraph speed method First, variable pole alignment speed method This kind of speed control method is to change the stator winding winding way to change the cage motor stator pole pairs to achieve speed control purposes, features are as follows: with hard mechanical properties, good stability; no slip loss, high efficiency; wiring Simple, easy to control, low price; stepless speed regulation, large level difference, can not get smooth speed control; can be used with voltage regulator, electromagnetic slip clutch with the use of high efficiency and smooth speed control characteristics. This method is suitable for production machinery that does not need stepless speed regulation, such as metal cutting machine tools, lifts, lifting equipment, fans, pumps and so on. Second, the frequency control method Frequency conversion is to change the frequency of the motor stator power supply, thereby changing the speed of its synchronous speed control method. Frequency converter system can be divided into AC - DC - AC inverter and AC - AC inverter two categories, most of the current domestic use - cross - frequency converter. Features: high efficiency, no additional loss during the speed control process; wide range of applications, can be used for cage type asynchronous motor; speed range, hard and high precision; technical complexity, high cost, maintenance and repair difficult. This method is suitable for applications requiring high precision and better speed performance. Frequency conversion speed is divided into the following basic frequency and frequency above the speed, the fundamental frequency is constant torque speed control mode, the frequency above the speed is constant power speed mode.
- 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 frequency converter used to do, why some motor with the inverter?
- Speed control, there are speed requirements of the place are in the inverter
- Q: The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!
- 1. submersible pumps are generally the problem, far away from the reflection voltage, the pump insulation breakdown, in particular, to better pump. 2. Distance away, the inverter and pump connection thicker. 3. Then on the output filter.
- Q: Three motors, if coupled with the governor speed, is it necessary to add the inverter?
- First, the frequency control: the use of frequency converter to change the frequency of the motor stator power supply, thus changing its synchronous speed control method for all motors, which is the most advanced, the most widely used speed control method.
