- 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 parts of the inverter composition
- Simply put, the inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit
- Q: 65w adapter and 90w laptop power adapter What is the difference?
- 65W and 90W is mainly based on your laptop power configuration, the general integrated graphics with 65W, discrete graphics because of the need for additional power supply, so the general need 90W, of course, there are some low-power CPU, such as 25WCPU , 35W, 45W difference, these are the beginning of the manufacturer according to the notebook's power consumption count a maximum power, and then give your laptop with adapter 90W adapter can replace 65W, as long as the interface is the same, but 65W instead of 90W sometimes there may be insufficient power lead to automatic shutdown. In general, the greater the number of watts, the larger the head, because the adapter is actually a coil will be 220V into 19V, according to the power to determine the head, the larger the watt, the same 19V, then the output current will be greater
- Q: What is the single axis of the inverter and multi-axis applications
- Inverter is the application of frequency conversion technology and microelectronics technology, by changing the motor power supply frequency and amplitude of the way to control the AC motor power transmission components.
- Q: Can the notebook's power adapter be mixed?
- At present, the market sales of notebook power is generally 90 watts and 65 watts two, using integrated graphics, or configure the low-end notebook, usually 65 watts. Using the independence was, the configuration of high-end, or the game audio and video of this, are generally 90 watts. If the laptop's power adapter is damaged can not be used, it is best to repair the department as soon as possible to repair. If it is for emergency, before using the two adapters to check the output power and current and voltage are conceded, as the adapter input current and voltage is not the same, should be the general household voltage is 220V, so almost all of the notebook power The adapter is 100-240V ~ 1.5A words, as long as the output current and voltage values, and wattage equal, and then one is the same interface, you can mix. In general, the voltage is stable, the output wattage is the same, the notebook is basically no harm.
- Q: Delta VFD-F frequency converter how to adjust the number of poles
- Look at the 07 motor parameters, I VFD-F instructions need, then the mailbox sent
- Q: There is no inverter comes with simple PLC programming function
- The inverter is an AC speed control device, like DC speed control device, DC speed is to change the armature and excitation current, and it is the input AC through the internal circuit into DC, DC and then DC, the last DC AC output, this is the original 50Hz frequency AC can output other frequencies of alternating current, because the speed v is proportional to the frequency f, so you can set the frequency of the inverter to change the speed of the control motor. It does not have its own programming function. But there are servo drives, in fact, is a frequency converter, but can handle some of their own signals, usually from the servo motor on the encoder, and then control the servo motor to achieve precise control.
- Q: What is the difference between AC and DC frequency converters?
- L inverter air conditioner refrigeration system components: inverter air conditioner by the compressor, evaporator, condenser, electromagnetic four-way valve, electronic expansion valve, defrost valve, double capillary and other components (see Figure II), work, air conditioner Room needs, automatic control of the inverter output frequency higher AC, the motor speed to speed up, the compressor cooling capacity increased to achieve the purpose of rapid cooling or heating, on the contrary, when the room cooling or heating less, Compressor to normal speed or lower speed operation, therefore, inverter air conditioner has a continuous cooling capacity adjustment, making the room temperature fluctuations smaller. In the process of compressor operation, the microcomputer system controls the inverter compressor at the same time, controls the opening degree of the electronic expansion valve, maintains the proper refrigerant flow, and directly changes the flow of the refrigerant in the evaporator to change its state, the compressor The speed corresponds to the opening degree of the expansion valve, and the displacement of the compressor corresponds to the supply amount of the expansion valve, so that the degree of superheat is not so large that the capacity of the evaporator is maximized, so that the refrigeration system The most efficient control.
- Q: What is the maximum speed adjustable for a 4-stage motor with a rated frequency of 50Hz / 60Hz?
- Motor speed and frequency of the formula N = 60f / p In the above formula N - the speed of the motor (r / min); 60 - per minute (seconds); F - power frequency (Hirsch); P - pole pairs of motor rotating magnetic fields. China provides the standard power frequency f = 50 weeks / second, so the rotation of the magnetic field of the size of the theoretical diameter only with the magnetic pole. The number of pole pairs is large, and the rotational speed of the rotating magnetic field is low.
- Q: 55 瓩 4 pole motor with a frequency of one hour can save much electricity
- Such as: 55KW motor full load operation, 1 hour with 55 degrees of power (according to the motor power slightly different changes),
