Screw Compressors

Screw compressors are more or less like a pump, and a continuous flow of refrigerant compared to the reverse. Reciprocal have a ripple. This results in smooth compression a slight vibration. The reverse, on the other hand, do pulsating sounds and vibration. They can be very noisy.

Screw compressors almost linear capacity management mechanisms. That leads to a great part of the load. Due to its smooth operation, low vibration screw compressors, as a rule, have more life than the reverse.

Centrifuges are in constant speed. These machines splash under certain conditions. This leads to reduced performance and high power consumption at part load. Screw compressors have proven themselves in difficult cooling devices, including and on Board ships. Today, screw compressors practically dominate reefer ships, transporting fruits, vegetables, meat and frozen products across the ocean with good reliability. These компрессоры replaced the traditional ship centrifugal.

Screw compressors were developed in Germany in the 1800s. They were patented in 1883 in Italy, but not in the United States until 1905. This type of compressor positive displacement compressors. This means that it uses to manage the rotor another rotor (twin) or gate rotors (single), to ensure compression cycle. Both methods use the injected water for cooling of compressed gas, the seal of the rotor or rotors, and lubricate the bearings.
