What is the working principle of the magnetic pump?

The working principle of the magnetic pump is that the motor drives the outer magnetic rotor of the magnetic pump to connect with the inner magnetic rotor through the magnetic field to drive the impeller of the magnetic pump to run. When the magnetic pump is full of liquid, the impeller continuously sucks in the liquid and continuously discharges the sucked liquid during the rotation process, and the impeller makes the liquid rotate in the pump. In this way, the pressure and speed energy of the medium produce centrifugal force. In this way, under the action of centrifugal force, the liquid along the impeller wheel from the center of the impeller is thrown around, and then through the pump shell discharge pipe, so as to transport the medium to the final destination.

What is the principle of electronic accelerator pedal?

The principle of the electronic accelerator pedal is: 1. When the driver needs to accelerate, step on the accelerator, the pedal position sensor transmits the sensed signal to the ECU through the cable. The ECU analyzes and judges, and sends instructions to the drive motor, and the drive motor controls the opening of the throttle. To adjust the flow of combustible mixture; 2. Under heavy load, the throttle opening is large, and there is a lot of combustible mixture entering the cylinder. If you use the cable accelerator, you can only control the opening of the throttle by the depth of the accelerator pedal, and it is difficult to adjust the opening angle of the throttle to reach the theoretical air-fuel ratio; 3. The electronic throttle can analyze and compare the various data collected by the sensor through the ECU, and issue instructions to let the throttle actuator act, and adjust the throttle to the best position to achieve different loads and working conditions. It is close to the theoretical air-fuel ratio of 14.7:1, so that the fuel can be fully burned.

The working principle of insulation monitor

The DC power supply of power plants and substations is a very large multi-branch power supply network as the security power supply and control signal power supply for the main electrical equipment. In general, one point grounding does not affect the operation of the DC system, but if the ground fault point cannot be quickly found and repaired, and another point grounding fault occurs, it may cause a major fault.

Electric heater principle and way to introduce

Electric heaters, a kind of equipment that converts our electric energy into heat energy by consuming electric energy, have achieved heating of materials that need to be heated. In the process of operation, the low-temperature fluid medium enters the input port when the pipeline is subjected to a certain pressure, surrounds the heat exchange runner set in the electric heating container, and adopts the principle of fluid thermodynamics to design the channel to bring out the high-temperature heat energy generated in the operation process of the electric heating element, so as to realize the temperature increase of the heated medium, and the outlet of the electric heater reaches the required high-temperature medium.

What is the principle of electronic water pump

An electronic water pump (also known as an electric water pump) is a water pump that uses electricity to drive it. It drives the impeller to rotate through the rotor on the motor drive bearing, so that the water is sucked in and sprayed out under the action of the impeller. Electronic water pumps can be used in a variety of applications, including water plumbing systems, HVAC systems, industrial processes, etc. Generally speaking, the mechanical principle of it is basically the same as that of the hydraulic water pump, but the difference lies in the driving force source.
