    How Does a Dehumidifier Work?

    With humid air crawling up your walls, few things can make a home so unpleasant. Whether your house is damp, or your humidity comes from indoor cooking or drying laundry, the result can be a dreaded musty smell, mold growth on walls, and an increased risk of respiratory illness. Fixing a major moisture problem can take time, so what do you do in the meantime? One solution is to buy a portable dehumidifier, an electronic device that removes moisture from the air. In this article, we will introduce the working principle of dehumidifier.

    Air Diaphragm Pump Working Principle

    The air operated double diaphragm pump relies on the air compressor to input the compressed air into the air distribution valve of the diaphragm pump to drive the connecting shaft in the intermediate body of the diaphragm pump to drive the diaphragm pump diaphragm in the medium chamber of the diaphragm pump body to do lateral stretching movement to achieve self-priming fluid. Positive displacement reciprocating pump. In the two symmetrical working chambers of the pump, an elastic diaphragm is installed in each, and the connecting rod integrates the two diaphragms.

    Hot Wire Anemometer: Working Principle and Functions

    The hot wire anemometer is a type of anemometer that converts the flow velocity signal into an electrical signal, and can also measure fluid temperature or density. The length of the hot wire is generally in the range of 0.5 to 2 mm, and the diameter is in the range of 1 to 10 microns. If a very thin metal film instead of a metal wire, which is called a hot-film anemometer. The function is similar to that of a hot wire but is mostly used to measure the flow rate of liquids. 

    Peristaltic Pump: Structure, Working Principle and Selection

    Peristaltic pump is also called peristaltic metering pump, constant flow pump, peristaltic hose pump. A peristaltic pump is a liquid transmission device that can control the flow rate. By repeatedly compressing the elastic tubing, the liquid in hose moves in a certain direction, and its flow rate is determined by the diameter of tubing and the compression speed. The liquid is delivered by alternately squeezing and releasing the elastic delivery hose of the pump. In this article, we will introduce structure, working principle and selection of peristaltic pump.

    How Does a Synchronous Motor Work?

    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.

    How Does an Air Pressure Regulator Work?

    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.

    How Does a Pneumatic Motor Work?

    The principle of the air motor is that a rotor with a number of vanes is enclosed in a rotor cylinder. Compressed air is supplied through one connection and air escapes from the other. For reliable starting, the springs press the vanes against the rotor cylinder and the air pressure always bears at right angles against a surface. This means that the resulting torque of the motor is due to the vane surfaces and the air pressure. In this article, we will talk about air motor working principle.

    Pneumatic Grease Pump Working Principle

    A pneumatic grease pump, also known as an air grease pump, or pneumatic butter machine, is a pressure-increasing machine professionally used to inject butter into the lubrication station. It is widely used in machine tools, equipment, automobiles, ships and other industries. With the continuous development and progress of the industry, it has contracted the use of lubricating grease in machinery. The traditional grease gun that relies on the arm to provide pressure has long been unable to meet the needs of the development of the times. How to better lubricate and maintain machine tools, equipment, automobiles, ships, etc. has become the mission of the butter machine industry, especially for the higher pressure of butter filling. The pressure ratio of the pneumatic grease pump is 40:1; 50:1; 60:1, and the oil output pressure is as high as 24-48MPa, which is equivalent to 240Kg-480Kg kg.

    DC Cooling Fan Working Pinciple

    Today, with the development of modern technology, many industries are applied to the cooling fan. With the changes in applications and ambient temperatures, fans that sometimes need different speeds are needed to meet demand. The fan has the characteristics of long service life, small vibration and low noise. This article briefly introduces the working principle of DC cooling fan.

    Flow Switch Working Principle

    The flow switch is mainly installed on-line or plug-in in medium pipelines such as water, gas and oil to monitor the flow of water in the water system. When the water flow is higher or lower than a certain set point, the output alarm signal of the flow switch is triggered and transmitted to the unit, and the system can make corresponding indication actions after obtaining the signal.

    Infrared Temperature Sensor Working Principle

    Infrared temperature sensor is an IR temperature sensor, its sensitive element and the measured object are not in contact with each other, also known as non-contact temperature measuring sensor. It can be used to measure the surface temperature of human body moving objects, small targets and objects with small heat capacity or rapid temperature changes, and can also be used to measure the temperature distribution of temperature fields.

    Industrial Endoscope Working Principle
