Windmills and wind turbines are two of the most prominent technologies for harnessing wind energy and putting it into practice. Since the early days, sailors have used the wind to sail sailboats on rivers and lakes. Wind power technology has been transformed many times in human history and over time has become one of the leading mechanically based renewable energy sources. Wind turbines remain a reliable and cost-effective technology for generating electricity without even producing harmful gases. In this article, you can know the differences between wind turbine and windmill.

ATO HMI touch screen can be connected to industrial control equipment such as programmable logic controller, inverter, DC speed regulator and instrument. Its display shows that the digital device that realizes the interaction of human and machine information through input unit to write working parameters or input operation commands. Now let’s program and test the HMI and PLC.

A current sensor is a device that detects electric current in a wire and generates a signal proportional to that current. The generated signal could be analog voltage or current or a digital output. The generated signal can be then used to display the measured current in an ammeter, or can be stored for further analysis in a data acquisition system, or can be used for the purpose of control. This article will explain how to use current sensor correctly.

With the growing market demand for fans, it has also been applied in various occasions and industries, although now DC fans and AC fans are everywhere in life, but many people are not very clear about these fans will be, so the following to introduce the difference between the two cooling fans. This article explains the differences between DC and AC cooling fans from five aspects.

In order to understand pickup ability to compare magnets, you need to know how we measure pickup ability and performance. We briefly introduce in this article. The weight form of the steel is very important. For example, a 50-pound nail is harder to "grab" than a 50-pound rebar. The rebar is flat and dense and can be very close to where the magnet's gauss strength is highest, allowing the magnet to "grab" more weight in the form of the rebar than in the form of a nail.

Diesel generator set is a kind of power supply equipment which takes diesel engine as the prime mover and drags synchronous generator to generate electricity. It has the characteristics of high stand-alone capacity, high power, simple maintenance, compact structure, etc. According to different control systems, diesel generators are divided into open-frame type, fully automatic type, one-button type, etc. This article mainly introduces how the diesel generator starts.

As with all continuous output pressure sensors, regardless of the application, the most sensitive component to the sensing diaphragm and most critical to the function of the pressure sensor is the sensing diaphragm. If it doesn't work, your readings will be incorrect, or in extreme cases, you will have no readings at all. 

When the hydraulic electric pump is in the self-priming state, if the oil inlet pipeline leaks or there is a large leak in the hydraulic cylinder, check valve, reversing valve, etc. in the system, the pressure will not rise. This requires finding the air leak, tightening and replacing the seal, and the pressure can be increased. The overflow valve is faulty or the adjustment pressure is low, and the system pressure cannot go up. The pressure should be re-adjusted or the overflow valve should be repaired. If the cylinder block of the hydraulic pump deviates from the valve plate and causes a large amount of leakage, the cylinder block may be broken in severe cases, and the mating surface should be reground or the hydraulic pump should be replaced.​​

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.

The variable frequency constant pressure water supply system takes the water pressure of the pipe network (or the user's water flow) as the setting parameter, and uses the pressure sensor to measure the water pressure in the water supply system, and then the pressure sensor will detect the signal 0-10V or 4~20ma signal. It is transmitted to the PID loop of the VFD, and after the VFD PID processing, the running speed of the water pump is adjusted according to the output frequency signal of the variable frequency drive, so as to realize the closed-loop automatic adjustment of the water pressure of the pipe network, so that the water pressure of the pipe network of the water supply system can be adjusted according to the setting.

Pressure sensor is a device that converts non-electricity into electrical signals. In modern industrial equipment, pressure sensors are an indispensable part of the reason. It can also be seen from the two aspects. Traditional industrial equipment, such as in its The necessary sensors are added to the device and equipped with precision measuring components, its function and accuracy can be improved; industrial equipment is used as the control object of the automation system or as the automation system. A part of the system must be compatible with the three parts of the automation system (detection, control, and execution) or provide interfaces to integrate them into an organic whole. To sum up, adding sensors as industrial equipment itself is a necessary condition for the replacement of traditional equipment displacement sensors.

Industrial endoscope is widely used in aerospace, energy and electric power, automobile manufacturing, fine chemicals and other fields, because it is an important tool for nondestructive testing, it must be well maintained and maintained in daily work. Such as handle gently and prevent damage; timely cleaning and safekeeping; lens and probe protection and so on. These are some common maintenance of endoscope. In this article, we will introduce maintenance of industrial endoscope in detail.

Industrial endoscope is a multi-disciplinary universal tool, its function is to bend the pipe deep exploration, can observe the parts that can not be directly observed, can observe the internal space structure and state in the sealed cavity, can realize long distance observation and operation. This article briefly introduces the scope of industrial endoscope.

Magnetic sweepers use the power of magnets to clean, they save you time. These machines are also known as magnetic brooms. You can use this sweeper to collect iron filings and scrap. 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.

Oil mist eliminator is suitable for CNC lathes, milling machines, hobbing machines, grinding machines, precision machining industries and other equipment that produce oil and gas and water vapor and oil mist recovery treatment in closed industry space. Especially suitable for bearing, gold shoe processing and other manufacturing industries, fully enclosed machine tools (especially grinding machines), closed air conditioning constant temperature workshop.

The VFD is generally not suitable for switching back and forth between devices such as output contactors, because its control is complicated. When the motor is switched, it may cause the motor to idle, and its phase is very different from that of the variable frequency drive output. There is a relatively large impact, which will affect the life of the IGBT of the inverter. The soft starter itself is designed with these in mind, using some phase-locked loop techniques to track. So when do you need a soft starter?

Gas detector is a kind of instrument for gas leakage concentration detection. It is mainly divided into portable gas detector, handheld gas detector and fixed gas detector, which detects gas species present in the environment with the gas sensor. The gas sensor is used to detect the composition and content of the gas. However, what precautions should be noted when using a gas detector?

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.

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.
