Don't panic when the evaporator melts, look here!

Although the evaporator is very useful, the evaporator defrosting electric heating tube burned out and the water collecting tray heating chamber burned out successively during use. So I will introduce the problems of the evaporator equipment and analyze the problems.

How much do you know about the operation of air compression system

According to the "Limited Values ​​and Energy Efficiency Grades of Positive Displacement Air Compressors" standard GB19153-2009, the input specific power values ​​of each energy efficiency level of screw air compressors can be found (the input specific power represents the specific exhaust pressure and flow rate range

Surface roughness is one of the reasons for the fracture of crankshaft of high-pressure air compressor

  The crankshaft is the most complicated part of the high-pressure air compressor, and its stability is directly related to the stability of the entire aerodynamic system. What we are mainly involved here are the matters that should be considered when desﰸ2䀀

The main difference between brushless DC motor and DC servo motor

Different definitions: (1) Brushless DC motor is a typical mechatronics product, which is composed of motor body and driver. Brushless motor refers to the motor without brush and commutator (or collector ring), also known as commutator less motor. As early as the 19th century, when the motor was born, the practical motor was the brushless form, that is, the AC squirrel cage asynchronous motor, which has been widely used. However, the asynchronous motor has many insurmountable defects, so that the development of motor technology is slow. The transistor was born in the middle of last century, so the brushless DC motor using transistor commutation circuit instead of brush and commutator came into being. This new type of brushless motor is called electronic commutation DC motor, which overcomes the defects of the first generation of brushless motor.

Series of hazards caused by poor compressed air quality to production

Compressed air is an important source of power in industry. Compressed air is the second largest power source in industry after electricity. Compressed air contains harmful substances such as water, oil, and particulate impurities.
