The development history of single screw machine

1. The history and current situation of single screw compressor 　　 In 1960, France's B. Zimmern proposed the idea of ​​a single screw compressor and obtained a patent. In 1962, the first prototype was trial-produced, and it was officially produced and put on the market by Peugeot in the early 1970s.

Cooling method of water-cooled chiller

Air-cooled chillers and water-cooled chillers are used for outdoor installation and operation. The air-cooled machine is directly circulated by air mechanically, and the machine's condensing coil directly expels the heat and cools it by atmospheric air.

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.
