Product Description:

Energy-saving Solutions for Enterprise
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:
)、Concentrate on solving problems of energy conservation, make enterprises’ energy-saving work reach new level and take their social responsibility
)、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 ").
)、Avoid the high-energy consumption enterprises are implemented differential prices because of the changes of national power regulation.
)、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).
)、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:How many types of CVT are classified?
classification: To achieve stepless speed change, according to the transmission can be used liquid drive, power transmission and mechanical transmission in three ways. Liquid drive Liquid drive is divided into two categories: one is hydraulic, mainly by the pump and the motor or composed of valves and pumps composed of variable speed transmission, suitable for small and medium power transmission. The other for the hydraulic, the use of hydraulic coupler or hydraulic torque transmission, suitable for high power (hundreds to thousands of kilowatts). The main features of the liquid drive are: speed range, can absorb the impact and prevent overload, transmission efficiency is high, long life, easy to automate: manufacturing precision requirements, the price is more expensive, the output characteristics of constant torque, Large, easy to run when the oil spill.
Q:The Schneider inverter reports the nlp command
1, the inverter control circuit with an external 24V power supply, the main circuit did not power 2, PO and PA between the short film can not cause this failure.
Q:Can the inverter be used to control the speed of the DC motor?
For the brush commutation DC motor, the speed of the output torque in a certain circumstances and the input voltage related. For this type of motor, use the inverter to control the output of the rectifier device that supplies power to the motor, which can control the speed. For the brushless DC motor, the controller is in accordance with a certain law to change the form of stator winding power supply to produce a rotating magnetic field to drive the rotor rotation. That is, the DC motor controller outside the part of the AC motor and the structure and the principle has not much difference (see below. For such motors, with the inverter to replace the controller, and control the same as the AC motor Control the speed.
Q:Will the 75KW4 pole motor can be used to increase the speed of the inverter?
China's power frequency 50hz, and the motor rated frequency match, blindly by increasing the frequency of the inverter output motor speed is not desirable, will affect the motor magnetic circuit, work is not normal.
Q:Octopus AC Servo motor can be driven with ordinary inverter?
If it is asynchronous motor, then take the power, voltage matching ordinary inverter drive no problem, you only need to enter the appropriate parameters, such as current, power size and other parameters, and then off-line parameters from the adjustment (if the vector control run), you can run
Q:Asus notebook power adapter how to open
Hi respectful ASUS users The power adapter can not be disassembled, and if your machine's power adapter is faulty, you can go to the local service center for testing.
Q:Oil-free vertical vacuum pump why a little negative pressure inverter on the torque limit
Here is not the inverter can solve the problem, you should first 220V single-phase AC rectifier for the DC (full-wave rectifier plus filter about 310 volts),
Q:5.5 kW 4-pole motor with the fastest speed can exceed the rated speed?
Because the frequency converter can reach 60 Hz frequency, while the three-phase power supply is the standard 50 Hz. So the inverter can make the motor speed faster than the rated 1500 rpm. The fastest up to about 1800 turn.
Q:What parts of the inverter composition
The main converter are: rectifier module, inverter module, capacitor, driver board, motherboard, shell composed of these parts!
Q:Laptop power supply 20V 3.5A can use 20V 4.5A power adapter Mody, what impact?
It's ok. As long as the voltage is appropriate on the line. Current value refers to the maximum current that can be output. How much depends on your computer. Or, with a big no harm, can only be better, if you can use a small, but a little longer charging time.
