What is the refrigeration compressor

With the improvement of people's living standards, refrigerator air conditioners believe that everyone is no stranger, they have become a necessity of our family life. But what about refrigeration compressors, how much do you know about it? In fact, refrigeration compressors are widely used in refrigerators, air conditioners and other mechanical equipment. If the refrigeration system is compared to the human body system, the refrigeration compressor is one of the most important components in the refrigeration system, and is the core and heart of the vapor refrigeration system. It sucks the low-temperature and low-pressure refrigerant gas from the suction pipe, and drives the piston to compress it through the operation of the motor, thereby realizing the refrigeration cycle. Next, I will introduce to you what are the precautions for refrigeration compressors and refrigeration compressor maintenance. <img src="{{media url=&quot;magefan_blog/What_is_the_refrigeration_compressor.jpg&quot;}}" alt="" />

Performance characteristics of Panasonic Minas series Panasonic AC servo

The output power of Panasonic AC servo motor is generally 0.1-100 W, and the power frequency is divided into 50 Hz, 400 Hz, etc. It is widely used in various automatic control and recording systems 1.Miniaturization design 1) Through the best thermal analysis of the driver, the miniaturization is realized. Compared with the past, the volume is 75% and the weight is 80% 2) The new punching process of thin die steel plate has greatly reduced the iron loss, shortened the motor length (70% in the past) and reduced the number of drive models. It adopts current grading method to prepare and maintain. One driver is suitable for multiple motors and can identify automatically.
