The advantages of air compressor asynchronous motor over traditional permanent magnet motor

The asynchronous motor is a three-phase induction motor, not the rare earth permanent magnet motor used in traditional electric vehicles. What are the reasons for this? The difference between induction motors and permanent magnet motors.

How much do you know about freezing oil

Although the refrigerating oil is only a small material, if you accidentally use inferior products, you can even burn the machine. I believe that many colleagues have often encountered it.

Evaporator fouling is harmful. Several common evaporator fouling measures must be

Evaporator and preheater fouling means that the concentrated salt wastewater contains a large amount of impurity salts, which form crystal nuclei after continuous evaporation and concentration.

How to speed up the evaporation and heat dissipation of cooling tower water

In the process of water cooling in the cooling tower, the water is formed into very small water droplets or very thin water film, which expands the contact area of water and air and prolongs

What are the reasons for the frost of the refrigeration compressor

The importance of the refrigeration compressor in the entire cold storage refrigeration system is self-evident, I believe everyone knows it. Next, let's watch Xiaobian teach you to turn things around.

What are the Major Causes of Variable Frequency Drive (VFD) Damage?

The larger the setting value, the higher the gain and the greater the stiffness. Under the same frequency command pulse condition, the position lag will be smaller.

Reasonably adjust the cold storage evaporator and defrost in time

Reasonably adjust the cold storage evaporator and defrost in time Generally speaking, every increase in the cold storage evaporation temperature can save energy Therefore, under the premise of satisfying the low refrigeration process of the product, the evaporation temperature can be increased as much as possible by adjusting the amount of liquid supplied. The thermal resistance of the frost layer is generally much larger than the thermal resistance of the steel pipe.

What are the irrelevant and unreasonable requirements in air conditioning procurement

As a device commonly used in daily life and work, the purchase demand for air conditioners is strong all year round. Looking through the bidding documents of the government procurement of air-conditioning projects,

Analysis of the principle of pneumatic energy saving in air compressor system

Analysis of the principle of "pneumatic energy saving" in air compressor system Basic principle: reducing air consumption is saving energy In the industrial field, compressed air is one of the most common energy sources used in the production process, and air compressors are like refrigerators everywhere in the house. The difference between it and the refrigerator is that the former is "pneumatic" and the latter is "electric." For pneumatic systems, reducing air consumption means saving energy.
