 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:Who knows how the inverter is calculated?
Quadrupole motor synchronous speed is: 1500 r / min, but the actual motor speed will be more than 14 turn.
Q:The inverter is running independently
. Main working circuit (1) Operation circuit: the external speed, torque and other instructions with the detection circuit current and voltage signal comparison operation, determine the inverter output voltage, frequency. (2) voltage and current detection circuit: isolation with the main circuit potential detection voltage, current and so on. (3) drive circuit: drive the main circuit device circuit. It is isolated from the control circuit to turn on and off the main circuit device. (4) speed detection circuit: mounted on the asynchronous motor shaft speed detector (tg, plg, etc.) signal for the speed signal into the operation loop, according to the command and operation can make the motor running at the command speed. (5) protection circuit: the detection of the main circuit voltage, current, etc., when the overload or over-voltage and other abnormalities, in order to prevent the inverter and asynchronous motor damage
Q:Is the laptop power adapter long-haul?
Oh, the power adapter is a transformer, we use the electricity is 220, after it will be converted into a suitable computer voltage, or notebook can not withstand 220V, so as long as the power inside the transformer will work, If you do not have a computer, it is best to unplug the plug on the power outlet, even if the computer has to pull out from the outlet, or will have an impact on the life of the adapter.
Q:ASUS notebook power adapter can be universal? is it?
ASUS notebook power adapter is not universal, depending on the model, the output voltage and current requirements are different, select the battery and consistent adapter. Note: different brands of laptop batteries may be different, so do not use, through the laptop battery voltage and current comparison power adapter voltage and current to judge. If the voltage and current are roughly the same can be used.
Q:Inverter signal line analog 4-20mA connection positive and negative can be reversed?
Inverter signal line analog 4-20mA connection when the positive and negative is not reversed. Inverter input analog signal is generally 4-20mA, 0-20mA, 0-5V, 0-10V and so on.
Q:Laptop power adapter problem
Second, the transformer This thing is not standardized production, the result is that even if the parameters of the same, the transformer to get another of this may not be compatible with the use of the explosion with the use of the cup like the situation, so we generally Stressed the original transformer.
Q:18: 5 kilowatts bipolar multi-pole pump motor with inverter
Under normal circumstances, with 15KW inverter on it.
Q:How to disassemble the notebook power adapter
HP laptop power adapter for the whole design of small sealed, you can follow the following steps to dismantle: 1, laptop power adapter for the injection molding package or with a strong adhesive glue, without any screws, so generally only with violence Cracked. However, as long as the method properly, after the dismantling of the power adapter can be restored to the original, do not carefully observe almost no traces of open.
Q:East yuan 7200GS inverter start 11KW 4-pole motor and 2-pole motor need to modify what parameters?
If you use the environment is relatively poor, it is recommended that you use Austrian St. sealed inverter, this inverter can be moisture, dust, water, oil, corrosion.
Q:Laptop power adapter current is not the same alternative?
because the output power is not enough, will burn. Note the voltage polarity!
