The water chiller is a water cooling equipment, which can provide constant temperature, constant current and constant pressure. The principle of the water chiller is that a certain amount of water is injected into internal water tank, making refrigerating system cools the water, and then water pump inside the machine injects cryogenic freezing water into an equipment which needs to cool back. The frozen water takes away calories inside the machine, then high temperature water backflow in water tank cools down. Cycle alternation cool reaches a function that cools equipment.

The "input" and "output" terminals of a isolation transformer should be short-circuited to test their insulation resistance against the ground wire by a megohmmeter. When measuring by 1000V megohmmeter, the resistance value is greater than 2M ohms. The cross-sectional area of the isolation transformer input and output power lines should meet the requirements of its current value. It is appropriate to configure the electric current density of 2 ~ 2.5a /mm2.

As an important form of energy generation, air compressors are widely used in various industrial fields, including mechanical, metallurgy, Electronic power, medicine, packaging, chemicals, food, textile, transportation and so on.
Direct drive of air compressor refers to the motor main shaft to drive the rotor by the coupling and the gearbox speed, which is not actually a direct drive in practical sense.
Direct drive in the true sense means that the motor is directly connected with the rotor (Coaxial), which has the same speed. This situation is obviously very rare. Therefore, it is a wrong view that there is no energy loss in direct drive.
Another drive way is belt driven, which allows the rotating speed of the rotor to be changed by pulleys of different diameters.

The principle of three-phase isolation transformer basically adopts the principle of electromagnetic induction. It is safe to use a three-phase isolation transformer, which is generally used as a maintenance power supply. The isolation transformer is commonly 1:1 transformer, but it has different specifications. Three-phase isolation transformers are used for changing voltage, lighting, power supply and rectifying power supply, widely applied to industrial and mining enterprises, power plants, airports, high-rise buildings, subways and other places with high fire safety requirements.

As a relatively safe transformer in the power industry, isolation transformer has been widely used in electronic industry or industrial and mining enterprises, machine tools and mechanical equipment in general circuit control power supply, safety lighting and indicator power. Due to its excellent product performance, isolation transformer has been used in more fields and scope, and may gradually replace the ordinary transformer. What's the difference? The following is a simple analysis of the main differences between the isolation transformer and the ordinary transformer.

The isolation transformer is a device adopting the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the core (magnetic core). The main functions are voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer) and so on. Due to its excellent product performance, isolation transformer has been used in more fields and scope. As we all know, power transformation relies mainly on the step-up & step-down transformer.

Isolation transformer is the transformer with electrical isolation between the input winding and the output winding. Isolation transformer is used to avoid users accidentally touching the charged body at the same time. Isolation transformer, whose transformer ratio is usually 1:1, is a special transformer with high insulation strength between the primary winding and secondary winding to isolate different potential to suppress common mode interference. The main function of the step-up & step-down isolation transformer is to completely insulate the primary side and the secondary side, and also to isolate the loop. In addition, the high frequency loss of the iron core is used to suppress the high frequency clutter into the control loop. 

Although three-phase isolation transformers and single-phase isolation transformers are different types of step-up & step-down isolation transformer products, they all have very similar functions and can be used for converting voltage and current, safe isolation and voltage regulation, and play a very important role in many professional fields. However, there are significant differences between them.

Toroidal transformer is a kind of step-up and step-down power supply device, which has the advantages of small volume, low noise, less heat and high performance. Generally, we use a variety of voltages, such as 220V for domestic lighting, 36V for industrial safety lighting, and the voltage of the welding machine needs to be adjusted. These cannot be separated from the toroidal transformer, which can step down the voltage we need through the principle of electromagnetic mutual inductance of the main and auxiliary coils. But how to improve the conversion efficiency of toroidal transformers has been a problem for many people. In fact, the conversion rate of a toroidal transformer is determined by the transformer's power, production materials, and its work site.

A mini linear actuator refers to a transmission device with a small volume and a small stroke. When searching for electric actuators, customers will add a mini in front. When some customers inquire through email, the most important thing they concern about is the installation size and stroke length. Generally, the installation size is required to be small, and the stroke can be different according to different customization.

Control transformer is a small dry-type transformer, which is mainly used to change the voltage of AC power. It is wound by an iron core and a coil. It can change not only the voltage of the alternating current, but also the impedance. When the design power is not exceeded, the current can also be changed. In different environments, the transformer also has different applications. Generally, it is used as a control lighting and indicator light source for electrical appliances in machine tools and mechanical equipment.

Air pollution, mainly comes from haze, dust particles, smoke, automobile exhaust, second-hand smoke, soot and so on. Indoor air pollutants are mainly from decoration, because the widely-used decorative materials, plate, paint, glue, new furniture, adhesives, etc., easily produce harmful pollutants to human health. Indoor air quality monitor can detect the dust particles PM2.5 in the air, and also detect the formaldehyde and TVOC produced by decoration. Air pollution is very harmful to the human body, so a reliable air quality monitor can help you detect the air pollution index at home, and offer a comprehensive protection to pregnant women, children, the elderly and family members.

The difference between limit switch and proximity sensor:

1. Proximity sensors are non-contact switches with a long life and are suitable for passing objects. Limit switches are contact switches. Due to the internal contacts, the working life is relatively shorter.
2. Limit switches are used for position detection in one direction. For two-way position detection, using a proximity sensor is better.
3. Use limit switch for protection function. Use a proximity sensor to detect when an object passes a certain point.
4. The limit switch usually has 1 NO + 1 NC contacts. Generally only one group of contacts is used, so there are 2 wires. Proximity sensors generally adopt 2-wire, 3-wire and 4-wire, so they have more wires than limit switches. Some proximity sensors have to confirm it is PNP or NPN based on the connected equipment.

People found that the air conditioner also has a little dehumidification function in the process of using the air conditioner. Nowadays, air-conditioning manufacturers have deliberately added a dehumidification mode based on the two modes of cooling and heating to increase the selling point of air-conditioning. However, consumers still have many doubts about whether to buy air conditioners or dehumidifiers. So which one is more cost-effective to buy a dehumidifier or an air conditioner with dehumidification?

Indoor air pollutants mainly come from decoration, decorative materials, boards, paints, wall paints, glues, new furniture, adhesives and other pollutants widely used in decoration which will harm human health. The air quality monitor is used to detect formaldehyde (HCHO), PM2.5, TVOC and temperature and humidity in real time. It is small and exquisite, easy to carry. Through the inner sensors, the monitor can accurately measure the concentration of pollutants, and calculate the air quality index AQI, and give an alarm when the concentration exceeds the standard.

The rated voltage of the magnetic particle clutch brake is DC24V, and the normal torque is 1Nm ~ 400Nm. The main torques of ATO magnetic particle brake are 6Nm, 15Nm, 25Nm, 50Nm, 50Nm, 100Nm, 200Nm, 400Nm.It utilizes the characteristics of magnetic particle to transfer torque, provided that the current is supplied. After a number of authoritative technical tests and experiments, it has been found that the relationship between the exciting current and the transmitted torque is basically linear. Therefore, it seems to be very simple and convenient to adjust the torque of the magnetic particle clutch brake. As long as the magnitude of the exciting current is changed, the torque of the magnetic particle clutch brake can be easily adjusted. In addition, adjusting the torque of the magnetic particle clutch brake usually requires a tension controller (manual or fully automatic). The tension controller outputs a controllable DC0 ~ 24V or 0 ~ 4A for driving the magnetic particle clutch brake, thus realizing the constant tension control of the winding/unwinding process.
