Product Description:

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:What is the principle and implementation of the inverter?
AC inverter principle. It is the first AC current will be converted into direct current, and then use the electronic components of the DC switch. AC power. General power of the larger inverter with a thyristor. And set an adjustable frequency device. The frequency in a certain range adjustable . Used to control the number of revolutions of the motor. The number of revolutions can be adjusted within a certain range. The frequency converter is widely used in the speed regulation of AC motor. Frequency control technology is an important development direction of modern power transmission technology, with power electronics Technology development, exchange 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 and other fields. Generally divided into rectifier circuit, flat wave circuit, control circuit, inverter circuit, and so on several major parts.
Q:Laptop power adapter is broken, which brand is better domestic
What brand of your laptop brand? It is best to be original,
Q:Inverter signal line analog 4-20mA connection positive and negative can be reversed?
Theoretically reverse seems to be possible, but the operation will be normal, you can do experiments to try what is the result. Various manufacturers of the inverter may be the treatment of this problem will be different.
Q:Inverter problem
(0 ~ 20mA), but the main input / output is completely isolated, than the output of the inverter simulation of the output of the analog output The amount of signal impact resistance, anti-interference ability.
Q:The motor is 2 pole with the inverter frequency to 50hz why the speed is only 1500 rpm
Motor speed formula: N = 60f / p In the above formula N - the speed of the motor (r / min); 60 - per minute (s); F - power frequency (hz); P - pole pairs of motor rotating magnetic fields.
Q:A 4-pole AC motor into a 2-pole AC motor, the motor is controlled by the inverter, to make the maximum speed of the 2-pole motor and the original 4-pole
If it is normal V / F control, then do not need to modify too many parameters to limit the frequency limit of 50%
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:Taian inverter 3.7KW 380V with 4.0KW 2 pole motor 18000 to 300HZ can it?
Second, is the higher speed, parking, inertia, the motor into a generator, to the module reverse power supply, resulting in the module burned, this time, should consider adding braking resistor and braking unit.
Q:65w adapter and 90w laptop power adapter What is the difference?
According to ibm specification T6 x6 r6 series power supply is compatible The difference is x6 this thin model with 65 The official explanation is (original English), in the 90w models using 65w machine may be in high power consumption, can not meet the system requirements. That is, while the side of the charge side of the use, it is possible that the computer can not run at full speed. In fact, the use of and there is no problem, but also little, at least the machine is no harm. For psychological factors, you can buy a 90w, Taobao fake a lot, you are not professional or to Jingdong to buy, about 250 yuan, although it is more expensive, really is the original.
Q:380V motor addition to the inverter, but also how to change its speed?
Rotary motor rotor series resistance adjustable speed. 4. Change the slip electromagnetic speed (slip motor)
