Ball valve and butterfly valve are the two most commonly used valves. Compared with other valves, the two are simpler and easier to operate, and they play a role in the control of cut-off and cut-off of the medium fluid in the pipeline. The ball valve is a control valve in which the opening and closing parts (balls) are driven by the valve stem and rotate around the axis of the ball valve. Butterfly valve, also known as flap valve, is a kind of regulating valve with a simple structure. Butterfly valve can be used for on-off control of low-pressure pipeline medium means that the closing member (disc or butterfly plate) is a disc, which rotates around the valve shaft to achieve opening and closing.

A synchronous motor is an AC motor in which the rotation of the rotor is synchronized with the frequency of the supply current. That is, the period of rotation of the rotor is equal to the rotating magnetic field of the machine in which it is placed. In this article, we will introduce synchronous motor working principle. The working principle of synchronous motor is magnetic lock. When two different magnetic poles meet, a huge pull-off force is created between the two magnetic poles.

Many of you are familiar with electroplating rectifiers. Through the electroplating rectifier, the AC power can be changed to DC power, which also shows the importance of the electroplating rectifier. We will encounter some failures in using the rectifier, and this article will introduce the plating rectifier troubleshooting.

The motor can be turned on "in reverse" and is called an induction motor, also known as an "asynchronous motor". This means that the rotor of the motor is placed in a rotating magnetic field, and under the effect of the rotating field, rotating torque is obtained, and thus the rotor of the motor rotates. The motor rotor is a rotatable electrical conductor, generally mostly in the form of a squirrel cage. The motor stator is the non-rotating part of the motor with the specific task of creating a rotating magnetic field. The rotating magnetic field is not accomplished by mechanical means. It is simply a cyclic transformation of the magnetic poles by passing alternating current through several pairs of electromagnets so that it is equivalent to a rotating magnetic field. Such motors do not have brushes or collector rings like DC motors, and there are single-phase motors and three-phase motors according to the type of AC power commonly used.

A centrifugal pump is a mechanical device designed to move fluid by transferring rotational energy from one or more driven rotors, called impellers. Fluid enters the rapidly rotating impeller along its axis and exits through the impeller's blade tips along its circumference by centrifugal force. The action of the impeller increases the velocity and pressure of the fluid and directs it towards the pump outlet. The pump casing is specially designed to compress the fluid from the pump inlet, direct it to the impeller, and then slow and control the fluid before discharging.

Air motors with simple structure, small size, strong power, water resistance, fire protection, moisture and explosion proof. In the following, we will introduce something abour air motor and. After reading this article, you can have a certain understanding of our air motor.

The linear servo motor is a modular product integrating servo motor and screw, the electric linear servo motor converting the rotary motion of servo motor into linear motion, while converting the best advantages of servo motor - precise speed control, precise rpm control and precise torque control into precise speed control, precise position control and precise thrust control; a new revolutionary product that realizes high precision linear motion series.

Air pressure regulator adjusts the flow of the medium by controlling the opening degree of the opening and closing parts in the valve body, reduces the pressure of the medium, and adjusts the opening degree of the opening and closing parts with the help of the pressure behind the valve, so that the pressure behind the valve is kept within a certain range. Inside, and spray cooling water in the valve body or behind the valve to reduce the temperature of the medium, this kind of valve is called a pressure reducing and desuperheating valve. The characteristic of this valve is to keep the outlet pressure and temperature within a certain range when the inlet pressure is constantly changing. The pressure reducing valve is an essential accessory of the pneumatic control valve. Its main function is to reduce the pressure of the air source and stabilize it to a fixed value, so that the control valve can obtain a stable air source power for adjustment and control. This type of valve should generally be installed horizontally in the pipeline.

With the development of new materials, mechatronics, power electronics, computers and other related new technologies, synchronous motor control system has opened up a wide range of applications, to achieve high speed, high precision, high stability, fast response, high efficiency and energy saving motion control. In industrial and agricultural production, there are a large number of production machines that require continuous single-direction operation at roughly constant speed.

The butterfly valve has a simple structure, small size, light weight, and few components. It is very convenient to open, just turn the switch to 90 degrees. The butterfly valve controls the fluid very well, and can increase or decrease the flow rate at any time. Generally, the valve has a certain resistance when transporting any fluid, and the resistance of the butterfly valve mainly comes from itself, such as the thickness of the butterfly valve body. If you want to reduce the resistance to the fluid, just reduce its thickness.

A linear servo motor changes the rotational motion of a motor into a straight line. Conventional electric motors move in a circle, while linear actuators move forward and backward. The push and pull action allows the device to slide, tip, and lift items with the push of a button. The design provides operators accurate and precise control over the production. The fluid movement means the linear actuator requires minimal maintenance over its lifespan and comes with natural energy efficiency. They are easier to install than their hydraulic or pneumatic counterparts, cost less, and take up significantly less room.

Air motors work with power from compressed air, such as an air compressor. air motors weigh less than many electric motors, have a simple structure and can easily switch between forward and reverse rotation. air motors can have a smaller installation size than electric motors with the same power output, and can be used environmentally, quickly and safely. This article briefly introduces the application of air motor.

Synchronous motors, like induction motors (asynchronous motors) are a common type of AC motors. Synchronous motor is the heart of power system, it is a set of rotation and static, electromagnetic change and mechanical movement in one, to achieve electrical and mechanical energy conversion components. Synchronous motors can be divided into reluctance synchronous motor, hysteresis synchronous motor and permanent magnet synchronous motor. In this article, we will introduce these three types synchronous motor.

Isolators and Circuit Breakers both are electrical devices used to isolate a section of power system. But what are the differences between them? In this video we are gonna make clear the differences between Isolators and Circuit Breakers which are to be explained considering factors such as type of device and their action, operation of both appliances, their functions, withstand capability and applications, etc.

ATO anemometers are used in health supervision, environmental monitoring, health and epidemic prevention, university academies, food safety, industrial pollution, heavy metal dyes, potions, chemicals, beverages, bacteria, sewage, pulp, pharmaceuticals, fermentation, electroplating, drinking water production workshops, Planting, breeding and fishing sites. Here's how to use an wind anemometer and its precautions:

An anemometer is an instrument that measures the speed of air. There are many types of it, and the three-cup anemometer is widely used. Robinson in the United Kingdom invented the rotating cup anemometer, and it was four cups at that time, and then it was changed to three cups. The three parabolic or hemispherical empty cups fixed to each other on the rack are all in one direction, and the entire rack together with the wind cup is mounted on a freely rotatable shaft. The three-cup anemometer commonly used in meteorological stations is composed of three parabolic cone empty cups fixed on the bracket at 120° to each other, and the concave surfaces of the empty cups are all in one direction. The entire induction part is installed on a vertical rotating shaft. Under the action of wind, the wind cup rotates around the shaft at speed proportional to the wind speed. Another type of rotary anemometer is the propeller anemometer, which consists of a three-blade or four-blade propeller to form a sensing part, which is installed at the front end of a wind vane so that it is always aligned with the direction of the wind. The blades rotate about the horizontal axis at a speed proportional to the wind speed.

Both air circuit breaker (ACB) and molded case circuit breaker (MCCB) are used for the safe switching on and off of electrical systems. In principle, both serve the same purpose. The ACB is usually found on the upstream side of the circuit, while the MCCB is found on the load-side control (usually, the load-side switch operates more frequently than the upstream). These three protection devices are selected according to the required operating voltage and protection level (fault level) of the system. As technology continues to advance, the ratings and breaking capacities of MCCBs are increasing, so the applications of ACBs and MCCBs may overlap.

Autotransformers and isolation transformers are two different forms of transformers that work on the same principle. Both use an energy conversion between the alternating magnetic field and the alternating current in the coil to convert the voltage. So what's the difference between them? The following article lists six major differences between autotransformers and isolation transformers.

A linear servo motor is a modular product that integrates servo motor and lead screw, linear servo actuator is a direct drive solution where the load is directly connected to the moving portion of the motor. Direct drive linear motors are available in a variety of configurations (iron core, U-channel, tubular) but ultimately work the same.

The wind meter (anemometer) is an instrument that measures the speed of wind. To determine wind speed, wind meters detect changes in certain physical properties of the fluid or the effect of the fluid on a mechanical device inserted into the airflow. There are many types of it. The most commonly used in meteorological stations is the wind cup anemometer. Its sensing part consists of three parabolic cone empty cups fixed on the bracket at 120°to each other. The concave surfaces of the empty cups are all in one direction. The entire induction part is installed on a vertical rotating shaft. Under the action of wind, the wind cup rotates around the shaft at speed proportional to the wind speed.
