What is a screw compressor?

The screw compressor is one of the most common compressed air production devices, the way it works is as follows:

After the device is turned on, the ambient air first passes through the air filter and enters the air conditioner unit. In the air conditioner, there are two spiral rotors in the shape of a male and a female, which rotate alternately with a very small distance and slack. are, the air in this section after entering the compressor is trapped in the space between the two spirals and the shell, and then due to the continuous volume reduction, the kinetic energy of the air molecules increases and compression takes place. The increase in pressure in screw compressors starts from one side, and at the end of the spirals, the compressed air comes out along with the oil, and after the oil is separated from the compressed air by the separator filter, the output air is stored in the compressed air tank after passing through the aftercooler. is made

Two common methods for assembling screw compressors

The assembly and construction of screw compressors can generally be divided into two categories: direct screw drive compressors and belt screw drive compressors. The difference between these two direct drive and belt drive compressors is actually in their power transmission system, which the best compressors in the world have designed and built direct coupling air compressors due to the increase in the life of the device.

Why direct drive compressors?

  • Due to the absence of a belt, no radial force is applied to the bearings of the electric motor and the airend, and it increases the lifespan of the compressor.
  • Unlike the belt drive compressors, which over time due to the shifting of the pulleys causes an axial force in the airend, and the application of this axial force to the bearings of the airend causes the air conditioning unit to lock, in direct drive compressors, this state will not occur.
  • Due to the lower number of vibrating parts, the direct drive system will have a lower level of noise pollution than similar systems.
  • Having fewer rotating parts in this system means less failure of the direct coupling system. In other similar systems, due to the increase in the working time of the belt or creating tension in the rotating parts (such as pulleys), more failure is observed.

What are the advantages of the compressor manufactured by Sharoo Turbo Compressor Engineering Group?

  • Very low noise and vibration with the low speed of the airend, higher efficiency than the belt series.
  • The central hub is made with precise machining for permanent and accurate alignment of the electric motor and the airend. As a result, not needing clock and re-alignment of couplings in repairs is one of the advantages of this series of compressors.
  • The quality and resistance of the coupling elastomer guarantees its smooth operation and long useful life.
  • Acordoni steel hose for oil and air is resistant up to 225 degrees Celsius.
  • In desert climates or environmental conditions with high temperature, one stage OVER SIZE air and oil radiator or high efficiency water chiller is used.
  • The service life of bearings and felt bowls increases significantly due to the removal of the radial force of the belts.
  • According to the standard, flexible connection is used in all the pipings connecting dynamic to static equipment.

A view of Sharoo Kompressor D series direct drive compressors

Why choose screw compressors equipped with VSD drive or variable frequency:

The most important reason for using VSD variable frequency screw compressors is to adjust the compressor speed based on the amount of air consumption and as a result significantly reduce energy consumption. In all compressors equipped with VSD, the amount of air production is precisely controlled according to the needs of the consumer by changing the frequency of electricity and as a result by controlling the speed of the electric motor. It is for use in various industries.

In this model, with the installation of VSD drive made in European countries (Fland, Italy and Sweden), it guarantees maximum saving in electricity consumption and energy storage up to 35%, no high starting current like star and triangle, slow and smooth starting, no loss Energy in no-load mode, reducing the sound of the device, increasing the useful life of the device up to 2 times.
