Frequency converters used in industry are divided into single-phase and three-phase. This is distinguished by the voltage of the main circuit power supply. Three-phase means that the main circuit must be connected to the RST three-phase 380 volt AC power single-phase main circuit is connected to the single-phase 220 volt LN AC power, and the output is also connected to the UVW three-phase line…
THE START Whether it is an industrial robot engineer or a PLC application engineer, they are all inextricably linked with electricity . A robot engineer with a monthly salary of tens of thousands, who dares to say that he has not installed electrical cabinets and connected wires? If you want to learn the wiring of the distribution box , it is enough to…
Stepper motors are often used for positioning control . It can control the angle of rotation (relatively speaking, distance) by the number of pulses output by the PLC , and the frequency of the pulses controls the rotation speed of the stepper motor. However, it is simple, economical and convenient to use in occasions where the control accuracy is not very high;…
Hydrogen chloride, with the chemical formula HCl, is a colorless gas with a pungent odor. A hydrogen chloride molecule is composed of one chlorine atom and one hydrogen atom. Its aqueous solution is called hydrochloric acid, also known as hydrochloric acid. Hydrogen chloride is very soluble in water. At 0°C, 1 volume of water can dissolve approximately…
With the development of biotechnology, cell culture has become an indispensable process in order to study cell signal transduction, anabolism, growth and value-added, etc. Cell culture refers to a method of simulating the internal environment (sterility, suitable temperature , pH and certain nutritional conditions, etc.) in vitro to enable it to survive, grow, reproduce and…
Nowadays, the environmental situation is grim, the environmental supervision and law enforcement tasks are becoming more and more onerous, and the depth and difficulty are also increasing. The supervision model is relatively simple, and the traditional environmental protection law enforcement methods can no longer meet the needs of the current environmental supervision work. The application…
