Q:How to choose the right inverter?
, fan, pump load This is the most suitable for use in frequency conversion speed of the scene environment, the inverter function technology is not too high requirements, the use of inverter energy saving effect is remarkable. For example: a large-scale heating equipment in a large-scale heating system, including blower, induced draft fan (centrifugal fan) inverter configuration configuration with the power of the P-type machine; water pump (centrifugal pump) inverter configuration configuration with the power of the P-type machine ; Conveyor pump frequency converter selection configuration with the power of G-type machine; belt machine (coal feeder) inverter configuration configuration to enlarge a file of the G-type machine; slag converter inverter configuration configuration to enlarge a file of the G-type machine; Crusher (coal crusher) inverter configuration configuration to enlarge a file or two stalls of the G-type machine.
Q:What is the meaning of the bipolar polarity in the inverter ah There is a +10V signal input is a -10V What is the meaning of ah?
Analog signal input: Reference setting Input voltage Positive terminal (0 --- 10V)
Q:My laptop can not use the power adapter, and can only use the battery, how is it ah,
Depending on your question may be the problem that the laptop's internal lines may be short-circuited 1, you can go to the video online to find the same type of machine disassemble video and then repair their own 2, get to the maintenance of the place to get on nothing
Q:What are the types of power adapter used in notebooks?
The regulator wants the laptop adapter to not waste energy or add harmonics to the electricity lines. The first factor is that the adapter should plug the plug without any load, and it should be as small as possible to absorb power (standby). People are accustomed to the laptop adapter inserted in the socket, but not connected to the computer, the request can prevent the loss of this situation. The second factor is the recent requirement that it requires a specific average power efficiency at different load conditions (25%, 50%, 75%, and 100%) and is implemented by the global regulatory agencies in order to facilitate compliance with the specification And reduce overhead costs. Finally, the European and Japanese mandated reduction harmonics requirements have been applied to laptop power adapters because they have exceeded these standard specifications for the 75 W input power threshold. In a sense, the mobile / universal features of the laptop adapter make it the first mass production power product subject to the IEC1000-3-2 specification.
Q:Oil-free vertical vacuum pump why a little negative pressure inverter on the torque limit
and then use the inverter into three-phase AC, 380 volts almost, Can only use the transformer rose to 380 volts.
Q:The laptop's power adapter is broken how much it costs
Buy a new, new price of dozens to one hundred. Notebook adapter, as long as the output current is greater than the old, the same voltage, with the brand can be interchangeable, Different brands of adapters to meet the above requirements, that is, insert the notebook connector is different, you can use scissors + tape,
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:How many types of CVT are classified?
CVT (Continuously Variable Transmission) technology that is continuously variable technology, which uses the belt and the working diameter of the main and driven wheel to match the power to transfer, you can achieve a continuous change in transmission ratio, resulting in transmission and engine conditions of the most Good match
Q:What is the characteristic of the variable pole speed method?
Third, cascade speed control method Cascade speed regulation refers to the winding motor in the rotor loop into the adjustable additional potential to change the motor slip, to speed control purposes. Most of the slip power is absorbed by the additional potential in series, and the additional device is used to return the absorbed slip power to the grid or to convert the energy. According to the slip power absorption and utilization, cascade speed can be divided into motor cascade speed, mechanical cascade speed control and thyristor cascade speed form, the use of thyristor cascade speed, which features: The process of the slip loss back to the grid or production machinery, the higher efficiency; device capacity and speed range is proportional to the investment province, for speed range in the rated speed of 70% -90% of the production machinery; Device failure can be switched to full speed operation, to avoid shutdown; thyristor cascade speed power factor is low, the greater the impact of harmonics. This method is suitable for use in wind turbines, water pumps and rolling mills, mine hoists, extruders. Fourth, winding motor rotor series resistance speed control method Winding asynchronous motor rotor series into the additional resistance, so that the motor slip increase, the motor running at a lower speed. The greater the resistance of the series, the lower the motor speed. This method is simple and easy to control, but the slip power is consumed in the form of heat. Is a level of speed, mechanical characteristics of soft.
Q:Yaskawa inverter reported base blockade what is the reason?
This is the base block command, when the external input block command signal, the inverter will appear this code, the code appears, the motor will be free to rotate, does not affect the use.
