In this article we will talk about the benefits of dehumidifiers.

Spectrophotometer, also known as spectrometer, is a scientific instrument that decomposes light with complex components into spectral lines. The measurement range generally includes the visible light region with wavelengths ranging from 380 to 780 nm and the ultraviolet region with wavelengths ranging from 200 to 380 nm. Different light sources have their own unique emission spectrum, so different luminous bodies can be used as the light source of the instrument.

A colorimeter is an instrument that measures the color characteristics of materials. The main purpose of the colorimeter is to measure and analyze the color, hue and color value of the tested material. In order to overcome or reduce the misjudgment caused by stability, reduce the economic loss of users, and improve the efficiency of the colorimeter, it is necessary for us to analyze the main factors of insufficient stability of the colorimeter detected by the sample. In this article, we will go into details.

The ball valve is evolved from the plug valve. It has the same lifting action of rotating 90°, the difference is that the cock body is a sphere with a circular through hole or channel through its axis. The ratio of the spherical surface to the channel opening should be such that when the ball rotates 90°, all spherical surfaces should appear at the inlet and outlet, thereby truncating the flow. The ball valve can be closed tightly with only a 90° rotation operation and a small torque. The completely equal valve body cavity provides a low resistance, straight-through flow path for the medium.

Linear guideways, also known as line rails, are used in high-precision or high-speed linear reciprocating motion applications. They can bear a fixed torque and can achieve high-precision linear motion under load.
Linear rails can be divided into roller linear guides, cylindrical linear guides, and ball linear guides. According to the nature of friction, linear motion guideways can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides, etc.

Ultrasonic thickness gauge is a high-precision thickness gauge that utilizes the principle of ultrasonic measurement and adopts a high-speed processor and high-integrated chip design to achieve portable, non-destructive, fast and accurate measurement of thickness and sound velocity of various materials. The ultrasonic thickness gauge is suitable for measuring the thickness of various materials, such as steel, various metals, glass, ABS, plastic, PVC, and ductile iron, that can use ultrasonic waves to propagate inside it at a constant speed and can be reflected from the back.

Locking plug is known as NEMA connectors. NEMA stands for the National Electrical Manufacturers Association, a USA-based organization that forms a set of globally recognized and internationally applied standards for the manufacturing of electrical equipment. These standards outline the voltage and amperage configurations of plugs and receptacles to make it easier for consumers to differentiate them. NEMA connectors, including power plugs and receptacles, are among the electrical product categories covered by NEMA standards.

Modern industrial automated machinery is powered mostly by motors. The torque generated from a rotating motor provides the driving force for moving conveyor belts, gears, chains and other mechanical components, so a motor naturally becomes such an integral part that is key to the driving system. When it comes to the protection of the core power part, you can't pay too much attention to it. Thermal overload relays are used to provide overload protection, open-phase protection and protection against the unbalanced current for motors and they can also avoid heating in electrical equipment. The thermal overload relay works by the thermal effect of electric current to push the action mechanism to make or break contacts for the protection of electrical appliances.

Most people understand that synchronous motors use power to generate motion. Some motors are powered by DC current, others by AC current, others by a combination of the two, and their specific method of energy transfer is unique to each motor. This article will focus on synchronous motor. It aims to explain the definition, features of synchronous motors and differences between induction motor, so that anyone looking to use one of these devices has the relevant information to do so.

Quick connector is a kind of coupling that can connect or disconnect pipelines without tools. the quick connector can be divided into the quick connector for air, quick connector for oxygen and fuel gas, quick connector for gas and liquid common, quick connector for oil and pressure, quick connector for inert gas, quick connector for cooling water and temperature oil, and quick connector for semiconductor. The structure of the quick connector can be divided into two-ended open and closed, two-ended open and closed, and single-way open and closed.

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.

ATO pneumatic grease pump is a kind of refueling equipment, which is widely used at present. It can replace oil in time for automobile maintenance and various mechanical equipment. The pneumatic grease pump with 3 gal~12 gal is the most powerful assistant in production and life. It is a kind of pneumatic tool.

A hydraulic hand pump uses human power as an input to generate a combination of pressure and flow, which then produces hydraulic energy. Based on the simple principle of a handle providing leverage to an internal piston, hydraulic fluid is delivered directly under manually applied pressure. The piston then forces the hydraulic fluid into the cylinder port. Water and hydraulic fluid are the most common fluids, but a variety of pressure media can be used.

These brooms are great for pulling any metal and steel parts. To name a few: staples, screws, iron filings, nails, nuts, shavings, pins, metal dust, barbed wire, etc.

Industrial endoscope is a type of visual inspection in non-destructive testing. Without dismantling the detected object, it directly reflects the internal and external surface conditions of the detected object (such as: cracks, burrs, welds, etc. inner surface quality). And at the same time of inspection, we can use industrial endoscope equipment to make dynamic video recording or photographic recording of the entire inspection process, and can quantitatively analyze the defects found.

An infrared temperature sensor is a sensor that uses the physical properties of infrared rays to measure, and only measures the surface temperature. Infrared light is also called infrared light, which includes reflection, refraction, scattering, interference, absorption and other properties. This property of infrared temperature sensor makes it have a wide range of applications.

Star delta starter is a starting device of asynchronous motors. The starting current of induction motors is relatively large during the starting process, so motors with large capacity can use the wye delta starter. The star delta starter is actually a step-down starter. When it starts, the stator winding of the motor is connected into a star shape, and when the speed reaches close to the rated speed, it is changed into a △ to reduce the starting current.
