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.

Q:HP laptop power adapter how to open
That thing is not generally no screws, is sticky together. If you want to split, can only use the blade along the seam a little bit of open
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:How many types of CVT are classified?
Power transmission Power transmission is basically divided into three categories: One is the electromagnetic sliding type, it is in the asynchronous motor to install an electromagnetic slip clutch, by changing its excitation current to speed, which belongs to a more backward speed mode. Its features simple structure, low cost, easy operation and maintenance: sliding the largest, low efficiency, serious heat, not suitable for long-term load operation, it is generally only used for low-power transmission. The second class is a DC motor type, by changing the magnetic flux or change the armature voltage to achieve speed. It is characterized by large speed range, high precision, but the equipment is complex, high cost, maintenance difficulties, generally used for medium power range (dozens to hundreds of kilowatts), has been gradually replaced by AC motor. Three types of AC motor type, through the pole, voltage regulator and frequency control. The most practical application for the frequency control, that is, using a horn to obtain variable amplitude power supply, and then drive the motor speed. It is characterized by good speed performance, large range, high efficiency, can be automatically controlled, small size, wide applicable power range: mechanical characteristics in the slow speed section of constant torque, low efficiency and low efficiency is not smooth, Maintenance need professionals. In recent years, the inverter as an advanced, excellent speed device rapid development of the mechanical CVT had a certain impact.
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
The upper limit frequency transferred to 25HZ, the number of poles changed to 2, try to run when the motor speed test
Q:The laptop power adapter is hot
My point of view: First: your laptop power supply in a small ventilation environment, resulting in poor heat dissipation, Second: the life of the power supply is 3-5 years, the gradual oxidation of electronic components and some of the aging components, resulting in no load and load a lot of power, Third: the battery close to each run, and then connected to the power, the power to the battery charger and notebook power supply, so the pressure is not hot strange.
Q:Will the motor suddenly stop when the inverter is suddenly powered down?
but there are exceptions, such as head pump, water hammer effect after power failure will make the motor Reversal
Q:55 瓩 4 pole motor with a frequency of one hour can save much electricity
It depends on what type of equipment you use, the average energy-saving fan pumps, about 25-40 between; generic class is based on the frequency you use to decide, according to the frequency you use with 50 Hz Compared to energy saving.
Q:Who knows how the frequency converter works
The inverter is actually an inverter, which first turns the alternating current into direct current, and then switches the DC power with the electronic components into AC power, and the inverter is equipped with a variable frequency The frequency is adjustable in a certain range, and it is used to control the number of revolutions of the motor, so that the number of revolutions can be adjusted within a certain range.The frequency converter is widely used in the speed regulation of AC motor. Technology development direction, 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 and other fields. Generally divided into rectifier circuit, flat wave circuit, control circuit, inverter circuit, and so on several major parts.
Q:Delta VFD-F frequency converter how to adjust the number of poles
Go to the official website of some inside a detailed description
Q:What is the difference between the electronic governor and the frequency converter on the motor speed regulation?
Electronic governor is the use of control thyristor conduction angle to change the motor supply voltage, the motor characteristics of the curve down to change the speed of asynchronous motor. Its characteristics are as follows: the motor speed adjustment range is small, low speed when the motor load capacity is poor, the speed decreases, the motor torque decreases, not applicable with constant load, when the speed is low, prone to stall phenomenon; Applicable to fan load. Inverter speed is to change the frequency of the motor to achieve the AC asynchronous motor speed adjustment, speed adjustment balance, the motor load characteristics do not change with the speed change, suitable for load adjustment and constant torque adjustment. Excellent performance, but the cost is higher.
