- Q:Variable frequency pump pressure in the very low flow instability, why?
- . If you want to stabilize the pressure, you must adjust the pipeline characteristic curve is the work point to enhance, so that you can both stabilize the pressure and adjust the flow.
- Q:Do you need to rectify before switching?
- I used to do the frequency of the words to be rectified
- Q:Acer laptop power adapter
- the price is not very clear. You can go online to see the price such as Taobao
- Q:Laptop power adapter bad what is the phenomenon?
- Either the power is bad or the machine on the power supply module is bad to repair service
- Q:What is the application of variable frequency speed control?
- In the second half of the 20th century, the power electronic devices from the SCR (thyristor), GTO (gate can be turned off thyristor), BJT (bipolar power transistor), MOSFET (metal oxide field effect transistor), SIT (electrostatic induction transistor ), SIT (Electrostatic Inductive Thyristor), MGT (MOS Control Transistor), MCT (MOS Control Gate) to today's IGBT (Insulated Gate Bipolar Transistor), HVIGBT (High Voltage Insulated Gate Bipolar Thyristor), Device To promote the continuous development of power conversion technology. Since the 1970s, pulse width modulation variable frequency (PWM-VVVF) speed control research has aroused people's attention. In the 1980s, the PWM model optimization problem, which was the core of the frequency conversion technology, attracted people's interest and made many optimization modes, in which the saddle-wave PWM mode was the best. The 20th century, the late half of the 1980s, the United States, Japan, Germany, Britain and other developed countries VVVF inverter has been put into the market and widely used.
- Q:What is the difference when using inverter frequency conversion ordinary motor and variable frequency inverter motor
- 2, the ordinary asynchronous motor is the cooling fan and motor spindle connection, the motor speed determines the cooling fan speed, low frequency when the motor rotation is slow, so the motor temperature rise is the principle.
- Q:Who knows how the inverter is calculated?
- There is no pole in the inverter, the electrode can be polarized, the greater the number of poles of the motor the slower the speed, please refer to.
- 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:Three-phase asynchronous AC motor speed control 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: Can be transferred in the speed of the process of slip loss back to the grid or production machinery, the higher efficiency; Device capacity and speed range is proportional to the investment province, for the speed range of 70% -90% of the rated speed of production machinery; Speed ??control device failure can switch 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.
- Q:Notebook power adapter on how to look at power
- then the same formula can be used to calculate: power (unit: W) = voltage (unit: V) × current (unit: A). For example: the power adapter only identifies the output voltage is 20V, the output current is 4.5A, then we set a formula to know the output power is 20 × 4.5 = 90W.
