How to maintain the lubrication system of the chiller

In the operation system of the chiller, more attention is paid to the refrigerant circulation system, the chilled water circulation system and the electrical control system of the refrigerator. The lubrication system is often overlooked. As everyone knows, this system is also very important to the chiller.

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.

Refrigerant filling

After the leak test of the refrigeration system is completed, it should be filled with refrigerant. However, the Freon refrigeration system must be vacuum dried before being filled with refrigerant. When the drying is not complete, the refrigerant cannot be filled.
