The internal structure and characteristics of the micro servo motor

A miniature servo motor includes a small DC motor, a set of variable speed (reduction) gear sets, a feedback adjustable potentiometer and an electronic control board. Among them, the high-speed rotating DC motor provides the original power and drives the variable speed (reduction) gear set to produce a high torque output. The greater the gear ratio of the gear set, the greater the output torque of the servo motor, that is to say, the greater the weight it can bear, the lower the speed of rotation it will be.

Analysis of the cause of excessive suction temperature of compressor

Analysis of the cause of excessive suction temperature of compressor The high suction temperature is mainly due to the increase of superheat of suction. Note that high suction temperature does not mean high suction pressure, because the suction is superheated steam. Under normal circumstances, the compressor cylinder head should be half cold and half hot. If the suction temperature is too high, the cylinder head will all heat up.

Anyone who understands the structure of industrial chillers should know that once the compression ratio of the compressor is too high

Anyone who understands the structure of industrial chillers should know that once the compression ratio of the compressor is too high, it will definitely reduce the work efficiency of the compressor, and the work efficiency of other components will also be reduced due to various reasons

The effect of insufficient refrigerant charge on the chiller

1. If the suction pressure and discharge pressure of the compressor are lower than the normal value, then you need to check to see if it is due to insufficient refrigerant charge.

The difference between independent and non-independent refrigeration units

The cold storage is a special place dedicated to refrigeration, and now it is mainly used to keep food fresh. With the increasing requirements for the freshness of food, the use of cold storage is gradually increasing.

Causes of non-condensable gas in refrigeration system

Causes of non-condensable gas in refrigeration system 1. Insufficient emptying of the refrigeration system before charging the refrigerant Before charging the refrigerator, the compressor cylinder in the refrigeration system, the condenser, the evaporator, and the piping of the system were filled with air. In order to eliminate these air before charging the refrigerant, the interior of the refrigeration system Vacuuming,

Air energy heat pump heating, what installation and use details need to be paid attention to

In the recent period, the term "coal to electricity" has frequently appeared in the vision of the broad masses of people. The reason is that many areas in Beijing, including Chaoyang, Haidian, and Tongzhou, have announced the results of the "coal-to-electricity" winning bid.
