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.

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:Huichuan frequency converter drag a 4-kilowatt four-pole motor to change the six pole can?
can. Re-enter the new motor parameters in the drive.Inverter motor power to 4KW, speed 980 can!
Q:Laptop power adapter is broken, which brand is better domestic
I suggest to buy a compatible adapter on it, because My HP is the power adapter is broken, I spent more than 20 yuan to buy a city, the normal use of more than a year did not find the problem.
Q:Laptop power adapter is used to do what
Power and charge the notebook. Equivalent to power, mobile phone charger.
Q:Who knows how the frequency converter works
3. Control circuit Now the basic converter with 16-bit, 32-bit microcontroller or DSP as the control core, in order to achieve full digital control. The frequency converter is the output voltage and frequency adjustable speed control device. The circuit that provides the control signal is called the main control circuit. The control circuit is composed of the following circuits: "operation circuit" of frequency and voltage, "voltage and current detection circuit" of main circuit, and "speed detection circuit" of motor. The control signal of the operation circuit is sent to the "drive circuit" and the "protection circuit" of the inverter and the motor Inverter to take the control mode, that is, speed control, turn control, PID or other means
Q:Can the notebook's power adapter be mixed?
This is a 90W power adapter This is Acer's 65W power adapter Here need to explain: General in the power adapter only shows the output voltage and current, not marked wattage, need to calculate their own. The value obtained by multiplying the number of voltages and the number of currents is the wattage. More on notebooks Related topics: Notebook forums hope that the above information is helpful to you
Q:First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
In the inverter in the following 18.5kw inverter will bring their own braking unit for some special occasions, such as the inverter at high speed due to production needs, must be 1 second, or less time to stop, in the stop when the frequency The internal DC bus voltage is too high, the inverter will be reported over-voltage fault, in the positive and negative connected bk-dk connected to a resistor to the inverter discharge, the inverter will not report over-voltage failure
Q:380V 2 pole motor can use the inverter?
Of course, the stator winding can be connected with concentric While enameled wire to be better, preferably 180 degrees or 155, and even dedicated enameled wire
Q:Laptop adapter heat
Therefore, in the design and production of switching power supply, we must choose high temperature components. Of course, be sure to control the temperature of the power supply within the allowable range of the application environment. First, the conversion efficiency should be designed as high as possible, and secondly, to use the pressure drop is small, low loss of switching components, the third is to be thermal design, cooling area to be as large as possible, more than 100W switching power supply Should have a metal perforated shell, or add a cooling fan. The current notebook power adapter power is generally around sixty or seventy W, the use of high temperature plastic fire sealed package, the internal heat generated by the plastic shell mainly distributed out. Therefore, the power adapter surface temperature is still quite high, the maximum temperature or even reach about 70 degrees! Think of the inside of the adapter, it is not like the fire! So, when you use the laptop, try to place the power adapter in a better place to ventilate heat, do not put books and the like on the power above. As for the kind of hot feeling, do not have to worry about is the power, not angry strange!
Q:How to lift Yaskawa inverter base blockade?
Unlock the base block of Yaskawa inverter: 1. If the Yaskawa inverter reported that the base blockade, we should first check the cause, parameter settings in strict accordance with the recommendations of professional engineers to set.
Q:Inverter alarm a043, how is it
When there is a signal failure, if necessary, use DTI Board, if necessary, change P215 In addition, for the synchronous motor (P095 = 12): the inverter is released until the motor is at rest
