Speed-regulating excitation system: The speed-regulating excitation system changes the speed of the motor through the change of the excitation current. It uses a constant excitation current to adjust the speed of the motor, and can adjust the speed of the motor to the required speed as much as possible. The speed regulation effect of the motor is greatly improved.

  4. Synchronous excitation system: The synchronous excitation system is a technology specially used for the synchronous motor of the power plant to adjust the bbbbb pulse of the encoder and control the output excitation voltage and current. Using the excitation current can accurabbby control the speed of the synchronous motor, thereby improving the speed regulation accuracy of the motor.

  5. Three-phase excitation system: The three-phase excitation system is composed of DC power supply and the bbbbb of three-phase excitation transbbbber. Its main function is to stabilize the running state of the motor. For example, when the excitation current is used, the load of the motor can be reduced, the anti-voltage fluctuation and load capacity of the motor can be improved, the stability of the motor can be effectively improved, and the loss can be reduced, thereby improving the efficiency and power factor of the motor.

  The excitation system is mainly used in the application of generators, motors and magnetic control systems. It is an important means to improve the efficiency and power factor of the motor, reduce losses and prolong the working life of the motor. The anti-voltage fluctuation perbbbbance of the excitation system is improved, which can effectively ensure the stable operation of the motor and reduce loss, thereby improving the efficiency of the motor, improving the power factor of the motor, and shortening the power generation time of the motor. In addition, the excitation system can also detect the temperature of the motor winding in real time, which can prevent the motor from overloading, thereby improving the regulation perbbbbance and stability of the motor. In addition, the excitation system can also reduce the jitter and noise of the speed-regulating motor to ensure the harmonious operation of the speed-regulating motor.

  1.2 Chemical Products Industry

  In the chemical industry, analyzing gases in rebbbbbbs and production processes can help improve product purity, reduce costs, and prevent safety accidents. It can also control thermal efficiency to reduce the amount of waste and the harm of pollutant emissions. Usage scenarios include: oil and gas field exploration, refinery processing process monitoring; It is better to pay attention when using open flames for high-power heating such as steel smelting and coking; Assessment of the source gas released from the seawater infiltration system in the battery intake guide breeding camp.

  1.3 Medical Health

  In hospitals or clinics, port servers/Doppler ultrasound, ventilators and other devices are commonly used to operate patients. Patients need to be given smooth breathing treatment according to order or spray agents. Moreover, when selecting a specific type of group stepper generator and gas conversion device (converter), medical research departments often use gas analyzers to observe the stability and reliability of their output, ensuring that such equipment is small, cost-effective, and meets technical requirements.2. Main components of gas analyzer

  Now let's take a closer look at what basic components are typically included in gas analyzers?

  2.1 Sensors

  Sensors are one of the most important components in gas analyzers. It can detect specific substances and convert the detection results into electrical or optical signals to output to the display screen for response. Choosing the appropriate type of sensor not only improves testing accuracy, but also greatly simplifies and quickly verifies data in practical operations.

  2.2 Heating elements

  Due to many standard conditions specifying the heating temperature of the tested sample, heating elements must be installed in certain aspects; If it is necessary to roast waste with extremely high water content, and problems such as "coke residue" and easy spillage occur frequently, the heating element can effectively help stabilize the various data tested in the pipeline of the stove.

  2.3 Display screen

  Display screens are influenced by different factors in terms of quantity, design, and quality. Most modern gas analyzers are equipped with a digital LCD display screen, which can visually display the detection results and provide many functional options to facilitate testing and calibration operations for users.

  2.4 Control module and power supply components

  The gas analyzer also requires a control module to command its workflow, such as how to monitor in real-time how it is difficult to remove waste or clean components within the value range; Also pair appropriate power components to ensure normal operation
