Energy-saving Solutions for Enterprise
◆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:Will the laptop's power adapter is not the original good?
- As long as the power and current are equal or slightly larger than the original adapter, but the voltage must be equal to the original adapter on the line.
- Q:How does the laptop's power adapter open
- First put the power adapter on a clean desktop, with electric knife to the upper and lower cover along the edge of the gap slowly pry open, you can also use the hammer gently tapping the back of the electric knife, so you can turn on the laptop power adapter
- Q:What is the number of parameters of the motor frequency of the Siemens inverter?
- Different types of Siemens frequency changer pole pair parameters different. 6SE70 is p109;
The following is the p109 parameter description:
For the synchronous / asynchronous motor input motor pole pairs of the function parameters.
If the rated frequency (P107) and rated speed (P108) change, automatic calculation
This parameter, if necessary, checks and verifies this parameter.
- for some of the pulsed encoders (P130 = 11, 12, 15, 16)
The maximum number of pole pairs of P109 = 15 can be achieved
- P109 must be written when the write function (P060 = 6) is implemented.
- Automatic calculation of the pole pair on the motor with regenerative feedback on the rated data
Number to be added.
Where the function map:
360.2, 361.2, 362.2, 363.2, 364.2
MM4 series is r313, which is calculated by the input rated frequency and rated speed calculated read-only value, must be selected in the p3900 to calculate the correct value. You can also set pole pairs by p314.
S120; G110; G120; G130; G150; S150 with MM4 series.
- Q:Laptop computer about electricity no electricity, is the power adapter problem?
- To judge this is very simple:
1. The computer is in the battery state to see if it works properly. If it does not work, the battery has a problem
2. Remove the battery from the computer with a power adapter to see if it is working properly. If not, there is a problem with the power adapter
3. If the two states can work that is the computer charge management part of the poor contact and other issues.
- Q:I have a 11KW-4 pole inverter, now with the 4KW-4 pole motor, what impact?
- The inverter burns should be.
Your motor overload is relatively large,
- Q:Three-phase asynchronous AC motor speed control method
- First, variable pole alignment speed method
This method is to change the way to change the stator winding red way to change the cage motor stator pole to achieve the purpose of speed, the characteristics are as follows:
With a hard mechanical properties, good stability;
No slip loss, high efficiency;
Wiring is simple, easy to control, low prices;
A level of speed, large difference, can not get smooth speed;
Can be used with the regulator speed, electromagnetic slip clutch used to obtain a more efficient smooth speed control characteristics.
This method is suitable for production machinery that does not need stepless speed regulation, such as metal cutting machine tools, lifts, lifting equipment, fans, pumps and so on.
- 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 a load, it may be less than the torque. So it can not run.
- Q:400w 6-pole motor should be equipped with much of the inverter?
- 400w 6-pole motor with frequency converter, as long as 1kw inverter can be a.
- Q:Pump frequency converter instantaneous restart and restart the problem
- Inverter speed:
Based on the advantages of speed control, energy saving and reliable operation, the frequency converter has gradually replaced the traditional variable speed, electromagnetic speed and voltage regulation. In the introduction of PWM flux vector control of the inverter a few years later, the end of 1998 and the emergence of DTC control technology inverter. ABB's ACS600 series is the first generation of DTC technology using the inverter, it can open the ring speed and torque for accurate control, and dynamic and static indicators have been better than PWM closed-loop control indicators. Direct torque control to measure motor current and DC voltage as input to the adaptive motor model. The model produces a set of precise torque and flux actual values every 25μs. The torque comparator and flux comparator compare the actual values of torque and flux with the reference values for torque and flux to Determine the optimal switch position. It can be seen that it is through the torque and magnetic flux measurement, instantly adjust the inverter circuit switching state, and then adjust the motor torque and magnetic flux, in order to achieve the purpose of precise control.
- Q:How to choose the inverter
- Look at the motor seat size is 7.5kw it, this model of the inverter manufacturers a lot of production, and are built-in brake unit, so in the function which are the same
It is important that the inverter life, stability, price comprehensive consideration
Mitsubishi, Panasonic, LG, Emerson, Yaskawa, Siemens and so on
