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: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 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:What is the adapter?
USB adapter Buy a USB adapter: http://cew.earch14 /usb-adapters Audio-Video Adapter: Also offers the following types of audio-video adapters: O DVI to HDMI audio video adapter O DVI to VGA audio video adapter O RCA adapter O SCART adapter O XLR adapter O audio adapter
Q:30 kW 6 pole frequency motor torque is how much
To know what is the use of ah, the inverter motor is the same with the ordinary motor, but to prevent the operation of a low speed plus a fan
Q:In the case of the inverter, why can not the normal operation after removing the gearbox? The motor is 4 pole.
If there is no load, the demolition of the gearbox is the same can be run.
Q:Do you want to pay attention to the number of poles of the motor when selecting the inverter?
Inverter selection is mainly to see the power, and then pay attention to voltage problems. Finally look at what your motor is carrying.
Q:380V motor addition to the inverter, but also how to change its speed?
Use the star connection to reduce the speed by changing the torque
Q:How to make the motor speed (control speed), can not use frequency
Do not use the variable frequency motor with the speed motor
Q:Inverter alarm a043, how is it
Check processing: Check if the cable is disconnected. Check the tachometer to shield the ground. The shield is not only on the motor side, but also on the inverter side The cable of the pulse encoder should not be disconnected. The pulse encoder cable can not be laid together with the power loop cable. Use only the recommended pulse encoder.
Q:Three sets of batteries (540V) DC power supply U / f inverter.
It is estimated that the battery should be string - and - series connection method, and then rectifier part of the converter (which may also be caused by the switch) is actually a series of diodes in series, positive and negative after the reverse is actually the battery is Negative shorts, resulting in burning, as to burn only one of the group of a few cells, it should be string - and - string and that group, because the parallel to bear it double voltage.
