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.

Recovery of Program Investment


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:Is the inverter output current proportional to the output torque?
The output voltage of the inverter is proportional to the frequency, which is to keep the motor flux constant, T = KIφ so the motor output torque is proportional to the inverter current.
Q:How does the spindle drive system of the inverter realize the positive and negative control of the main pole?
Communication can reach a longer and more stable, generally better of the city 485
Q:On the notebook power adapter output current and voltage issues
This look at your computer is what brand if it is DELL may not be charged, some other brands can be used with some can not, if you can use the charge can then only charge time will be longer than the original power supply, the computer no effect, The current is not bigger than the original big line for a long time on the battery and the motherboard is not good!
Q:Will the asynchronous motor pole change the number of speed control can also be combined with the frequency converter
Of course, because the factors that determine the speed of asynchronous motor power supply voltage, frequency and motor pole pairs, so asynchronous motor speed can be achieved by changing the number of magnetic pole pairs, but this method needs to make a greater motor changes, Trouble, and change the number of poles can only achieve a single speed change;
Q:Does the teacher know the working principle of the inverter?
The AC power rectification of the grid input is changed to direct current, and then the direct current is changed from AC by the control circuit according to the user's setting. The frequency is determined by the user. The motor is operated at this frequency to reach the change frequency. the goal of.
Q:A water supply project, how to choose electrodes and frequency converters, such as giving a 7-storey water supply
2 pump power: If there is a tank, optional small pump, or should see how many households, fixed flow.
Q:Which machines are used for the frequency converter
Frequency converter is widely used in the speed regulation of AC motor.Varameter speed control technology is an important development direction of modern power transmission technology, with the development of power electronics technology, AC frequency conversion technology from theory to practice gradually mature. Inverter not only smooth speed, large range, high efficiency, start current is small, smooth operation, and energy saving effect is obvious. Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply, air conditioning and other fields.
Q:Please recommend a high performance laptop power adapter?
Power adapter can recommend you what model you get what model ah he is a standard can not just recommend
Q:What are the differences and links between the soft starters and the frequency converters, and their respective principles and uses?
The soft starter is activated by adjusting the voltage and current, and the frequency converter starts the motor by changing the frequency of the power supply. The soft starter can theoretically smooth and gradually start the motor to the maximum speed. No impact current (ordinary start-up current is 6-7 times the rated current) The inverter is best suited for tap water and fans, etc. The soft starter is not suitable for everything except for heavy load start.
Q:What is the difference between variable frequency motor and variable speed motor?
so the output torque will not change, that increase the current work is useless work. Variable frequency motors are generally used for deceleration, and in accordance with the law to adjust the voltage and frequency, that is, no matter how changes, the voltage divided by the frequency is a constant value.
