- Q:The laptop's power adapter is too hot to do
- Installed adapter heat should be no problem, I am now under the books, the fan mouth is very hot, the weather may be more and more hot it
- 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:Can the laptop power adapter be generic?
- Not common. Different computer adapter interface is not the same, and the voltage, current is not the same. If just the same, you can use, the voltage can also be used.
- Q:Is the laptop power adapter AC and DC?
- Most laptop power adapters can be used for 100 ~ 240V AC (50 / 60Hz). Basically, most of the notebook computers are external power supply, with a power cord and the host connection, which can reduce the size and weight of the host, only a very small number of models built in the host power.
- Q:Lenovo laptop power adapter side of the feet which is positive
- Lenovo laptop power adapter side of the mouth there are clear signs positive and negative, N on behalf of the positive, L on behalf of the negative, it is recommended to carefully look at that you can know.
- Q:2 pole 0.75 kW motor can increase the speed through the inverter?
- if the 4-pole motor to rise to 2-pole motor frequency, The frequency of the motor rises to about 100 Hz, which is easy to implement for the frequency converter.
- Q:Can different brands of laptop power adapters be generic?
- First look at the specifications, voltage, power, current, are matched after looking at the interface, all the same can be used, or else the two are bad.
- Q:Yaskawa inverter reported base blockade what is the reason?
- Yasukawa compared garbage on the signal board on the small line of poor oxidation, and get like, this is a weak signal, and safety relays connected, do not use high-grade security circuit with a small line short, Yasukawa A 1000 factory is short for a long time after the oxidation of the base blockade
- Q:Three-phase two-pole motor can be used to reduce the frequency of the inverter
- With the electromagnetic governor can be, cheap only 50 yuan or so
- Q:The laptop's power adapter can be used on a desktop computer
- Desktop machine is called DIY it ~ is the assembly machine inside the motherboard graphics card hard drive memory What is the need for power supply every power to have a different interface
