    Step Up & Down Transformers Introduction

    Transformer is a device that transform AC voltage, current and impedance. It uses the principle of electromagnetic induction to transform AC power of one voltage level into AC power of another voltage level. When an AC current is passed through the primary coil, an AC magnetic flux is generated in the iron core, causing a voltage (or current) to be induced in the secondary coil. It is composed of an iron core and a coil. The coil has two or more windings. The winding connected to the power supply is called the primary winding, and the remaining windings are called the secondary winding.

    Transformer mainly uses the principle of electromagnetic induction to work. The specific process is when an AC voltage U1 is applied to the primary side of the transformer, and the current flowing through the primary winding is I1, the current will generate alternating magnetic flux in the iron core, which makes the primary winding and the secondary winding electromagnetically connections.

SCR power regulator works by means of an intelligent digital control circuit. Its precise control of voltage, current and power makes for precise temperature control. And its advanced digital control algorithm greatly improves energy efficiency, which highlights its important role in saving electric energy. Power regulators are becoming an indispensable equipment in the automation industry.

    Working Principle of Air Blower

    The air blower is mainly composed of the following six parts: motor, air filter, air blower body, air chamber, base (and oil tank), oil dripping nozzle. The air blower operates by the eccentric rotor in the cylinder, and makes the volume change between the blades in the rotor slot to absorb, compress and eject the air. During the operation, the pressure difference of the air blower is used to automatically send the lubrication to the oil dripping nozzle and drop it into the cylinder to reduce the friction and noise, while keeping the gas in the cylinder from returning. Air blowers are mainly divided into roots air blower, centrifugal air blower and rotary air blower. The working principles of different types of air blowers are different.

    How does a PLC Work?

    Programmable Logic Controller, short for PLC, is a digital electronic device with a microprocessor. The device is a digital logic controller for automatic control, which can load control instructions into the memory at any time for storage and execution. The programmable controller is composed of internal CPU, instruction and data memory, input and output units, power supply modules, digital and analog units.

    When the PLC is put into operation, its working process is generally divided into three stages, namely input sampling, user program execution and output refresh three stages. Completing the above three stages can be called a scan cycle. During the entire operation, the CPU of PLC repeatedly executes the above three stages at a certain scanning speed.

    How Does Vacuum Pump Work?

    Vacuum pump is a kind of equipment that evacuates the pumped container to obtain a vacuum by means of mechanical, physics, chemistry or physical Chemistry methods. The gas is absorbed in from the air inlet and enters the cavity of the frontline pump through the ventilation/isolation valve. In the pump, the gas is conveyed. When the inlet is closed by the blade, the gas is conveyed and compressed. During the transferring process, the oil is transferred from the oil injection port and inhaled into the cylinder.

    How Magnetic Flow Meter Works?

    A magnetic flow meter, mag meter, or electromagnetic flow meter is a kind of instrument which measures the volume flow rate of the conductive fluid based on the principle of Faraday's Law of Electromagnetic Induction. With a large measurable flow range, the ratio of the maximum flow rate to the minimum flow rate maintains above 20:1. The mag flow meter is suitable for wide range of industrial pipe diameter, and the maximum can reach up to 3m. The output signal and the measured flow are linear, and the magnetic flow meter has high measurement precision. It can effectively measure the flow rate of fluids with a conductivity more than 5μs/cm, such as acid solution, alkaline solution, saline solution, water, sewage, corrosive liquid, mud, ore pulp, and paper pulp. Nevertheless, the electromagnetic flow meter cannot be used to measure the flow of gases, steam and purified water.

    How Does a Combustible Gas Detector Work?

    Combustible gas has certain characteristics of diffusion. In order to prevent the accidents caused by combustible gas leakage, the key lies in effectively controlling its continuous diffusion. Moreover, flammable gases will spread quickly driven by external forces. As a result, burning and explosion will take place. How to prevent the occurrence of this kind of accidents? What we need to do is often detecting the concentration of combustible gas whether it exceed the standard. Once the concentration exceeds the standard, give an alarm quickly and we take actions immediately. Here combustible gas detector plays an important role.
    A combustible gas detector is a detector that monitor the concentration of single or multiple combustible gases and give an alarm. Combustible gas detectors are mainly divided into two types, catalytic type and infrared optical type base on the working principle.

    Induction Motor Working Principle

    Through the relative motion of the rotating magnetic field generated by the stator (its speed is synchronous speed n1) and the rotor winding, the rotor winding cuts the magnetic induction line to generate induction electromotive force, thus induced current is generated in rotor winding. The induction current in the rotor winding acts on the magnetic field to produce electromagnetic torque, thus making the rotor rotate. As the rotor speed approaches the synchronous speed, the induced current decreases and the electromagnetic torque decreases accordingly. When the asynchronous motor works in the motor state, the rotor speed is smaller than the synchronous speed. In order to describe the difference between rotor speed n and synchronous speed n1, slip ratio is introduced.
