Common physical and chemical methods for removing scale in condensers in chillers

The water chiller is prone to scale formation in the condenser pipe after long-term use. If it is not treated in time, these scales will affect the heat exchange effect and cause the condensing temperature of the unit to increase

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.

Air compressor installation rules

1.Installation The selection of the installation site is most ignored by the staff. Often after the compressor is purchased, it is randomly located and used immediately after piping. There is no prior planning at all. Little did they know that such a sloppy result would cause future compressor failure and maintenance difficulties and poor compressed air quality.
