Cold storage anti-corrosion and anti-frost coatings effectively solve the problem of frosting and corrosion

In the cold storage, when the dew point of the air is lowered by the cooling pipe surface, the moisture in the food and air will precipitate and condense on the pipe wall. If the pipe wall temperature is lower than 0°C, it will condense into a rain layer.

The function and basic performance of the pressure reducing valve of the compressed air filter

The filter, pressure reducing valve and lubricator together form a pneumatic triplet. The filter is mainly responsible for filtering the liquid water, oil and impurities in the compressed air, the pressure reducing valve is mainly responsible for controlling the system pressure, and the oil mist device is responsible for the oil lubrication of the back-end components.

Basic principle and optimization algorithm of BLDC

Brushless direct current motor (BLDCM,) gets rid of the inherent shortcomings of the brushless DC motor, and replaces the mechanical motor rotor with the electronic motor rotor. Therefore, the brushless DC motor not only has the excellent speed characteristics of the DC motor, but also has the advantages of simple structure, no commutation flame, reliable operation and easy maintenance.
