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.

3、Program Features
High energy-saving efficiency
The project saving rate is generally 10% -30%, highest is up to 70%.
Clients Zero Investment
All works of design, audit, manufacturing, construction, monitoring are handled by RXPE, clients does not require investment.
Energy-saving Guarantee
RXPE promises the amount of energy saving, ensuring that clients’ cost reduction immediately.
Short Investment Recovery Period
The investment recovery period is short, average period is 3-4 years.
Low Risk
Customers do not input large sums of money also can enjoy professional energy-saving products, technologies and services, and the investment risk is very low.
Improvement of Cash Flow
Customers with the support of RXPE approve energy-saving program to improve cash flow, invest the limited funds into other priority investment areas.
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:With the inverter control fan 37Kw4 pole with what model inverter
If the speed is not very high requirements, all the general-purpose inverter can be.
Q:5.5 kW 4-pole motor with the fastest speed can exceed the rated speed?
The speed of the AC motor is related to the frequency of the power supply. Frequency AC frequency of 50hz, asynchronous motor rated speed of about 1440 r / min, increase the frequency of course can improve the speed, naturally can exceed the rated speed, provided that the motor load to be reduced. If you need to improve more, need to replace the inverter motor, improve the motor heat dissipation characteristics.
Q:Taian inverter 3.7KW 380V with 4.0KW 2 pole motor 18000 to 300HZ can it?
The existing Taian inverter 380V3.7KW can bring 4.0KW 2 pole motor, 18000 to 300HZ can also see how you load, It is best to check your wiring tightness and whether the load is stuck. It is recommended to use the N310-4005-S3 this model, such as with the E510-405-H3 better.
Q:Is the laptop power adapter AC and DC?
In the power adapter has a nameplate, marked above the power, input and output voltage and current and other indicators, with particular attention to the input voltage range, if the nameplate indicates that the input voltage is AC 110V, then in China's 220V mains voltage Plug it will burn.
Q:The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!
The following describes the selection of the inverter Note: The inverter selection is mainly driven by the load characteristics and the actual motor current to set, in addition, there are the following precautions. 1, the environment: for some high temperature (higher than 50 degrees), high altitude (more than 1000 meters) of the application, the inverter selection should be appropriate to leave a margin to ensure that the inverter and motor life. 2, distance: the location of the inverter installation and drive the distance between the motor more than 50 meters, the frequency changer selection should cooperate with the reactor to reduce the carrier frequency. 3, a drag: a drive drag more than one motor, if the middle of the cable is too long, universal inverter selection will enlarge the use of a file, and each machine should be installed behind the fuse.
Q:Inverter with 2.2KW 6 pole motor. 1 minute 8 times reversing often burn the motor, how to solve. For the 2 pole 4KW motor is the same.
3. Can try (the effect is not necessarily), for a large inverter and variable frequency motor, and the inverter installed braking unit, braking resistor.
Q:6-pole motor, speed 8000 rpm, corresponding to the frequency converter output frequency is how much?
To 400HZ, so high frequency you tried it? I only tried 80HZ, if you tried, please tell me some of the high frequency of the actual situation will produce some changes in the motor,
Q:How to disassemble the notebook power adapter
. 2, the power adapter on the side of the lateral side of the white paper, with an electric knife blade along the power adapter under the cover between the gap cut, and then hit the electric knife knife with a hammer, so that the electric knife from the adapter between the upper and lower cover cut into. In the different positions of the gap between the upper and lower covers of the adapter, use the tip of the electric knife to be scratched along the gap. When the upper and lower covers are first split, the depth of the tool is deep and then the upper and lower covers of the adapter are separated
Q:On the laptop power adapter problem
Notebook power adapter matching the principle of the principle is: the input voltage to meet the requirements of the domestic exchange is 220V; output voltage and the original with the same output current must be greater than or equal to the original adapter output current, your future output current is less than the original will appear Power from time to time unexpected shutdown caused by increased data loss, the battery charge is not easy to rush to cause the battery aging process, the other adapter long-term work will increase the heat caused by increased safety risks.
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
