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: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:30 kW 6 pole frequency motor torque is how much
30 kW 6 pole frequency motor torque is how much 860. 1, the motor torque calculation Motor "torque", the unit is N? M (beef) 2, the formula is T = 9549 * P / n. 3, P is the motor rated (output) power unit is kilowatts (KW) The denominator is the rated speed n units are per minute (r / min) P and n can be found directly from the motor nameplate.
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:I have a 5.5 kilowatts of 4-pole motor, want to pass through the inverter, slow down to 130 per minute use, eliminating the need for speed,
Power will drop, down to the original one-tenth
Q:Siemens g120 inverter torque limit what is the meaning
Torque is a strain, the inverter can not actively control the output torque size, only according to the size of the load demand torque, the output of the corresponding torque.
Q:What is the characteristic of the variable pole speed method?
Three-phase asynchronous motor speed formula: n = 60f / p (1-s) From the above equation can be seen, change the power supply frequency f, the motor pole p and slip rate s can achieve the purpose of changing the speed. From the nature of the speed point of view, different speed control mode is nothing more than to change the AC motor synchronous speed or do not change the synchronous turn two. In the production machinery is widely used does not change the synchronous speed of the speed control method There are winding motor rotor resistance, chopping speed, cascade speed and the application of electromagnetic slip clutch, hydraulic coupling, oil film clutch, etc. Speed ​​control. Change the synchronous speed of the stator to change the number of pole pairs of multi-speed motor, change the stator voltage, the frequency of the frequency control can not change the motor speed and so on. From the energy point of view of the speed control point of view, there are two methods of efficient speed control and inefficient speed control: high speed control when the slip rate is constant, so no slip loss, such as multi-speed motor, frequency control As well as the speed loss can be recovered speed control methods (such as cascade speed, etc.). There are slip loss of the speed control method is a low efficiency, such as the rotor string resistance control method, the energy loss in the rotor circuit; electromagnetic clutch speed control method, the energy loss in the clutch coil; hydraulic coupling speed , Energy loss in the oil of the hydraulic coupling. In general, the slip loss increases with the speed range, if the speed range is not large, the energy loss is very small.
Q:Inverter principle eff23
Low-voltage general-purpose inverter output voltage of 380 ~ 650V, the output power of 0.75 ~ 400kW, the operating frequency of 0 ~ 400Hz, its main circuit are used to pay straight to pay the circuit. Its control has gone through the following four generations. 1U / f = C sine pulse width modulation (SPWM) control mode is characterized by simple control circuit structure, low cost, mechanical properties of hardness is better, to meet the general requirements of the smooth transmission speed, has been in various fields in the industry Widely used. However, this control mode at low frequencies, due to the lower output voltage, the torque by the stator voltage drop is more significant, so that the maximum output torque reduction.
Q:How to disassemble the notebook power adapter
HP laptop power adapter for the whole design of small sealed, you can follow the following steps to dismantle: 1, laptop power adapter for the injection molding package or with a strong adhesive glue, without any screws, so generally only with violence Cracked. However, as long as the method properly, after the dismantling of the power adapter can be restored to the original, do not carefully observe almost no traces of open.
Q:Laptop power adapter output voltage is not the same as the current? What's the effect?
so this replacement is generally feasible in the general use , But the remaining power supply power margin is very small, once your books took a lot of peripherals, such as two usb hard drive, and then cpu full speed operation, and then a base, the above to drive a full speed to read the disk, plus While charging the battery, it is estimated that the danger, and at any time to touch your power is not already already boiled eggs. 72w more than the 56w adapter 16w is to cope with this situation. So it is best not to use a small current instead of high current power supply
Q:Do you want to pay attention to the number of poles of the motor when selecting the inverter?
Inverter is generally selected by the power, do not consider the number of poles, but the inverter output current is controlled by the module, so you can choose in the selection as much as possible in accordance with the rated current to select the inverter. And left redundant party B overload and other phenomena.
