Of all the different types of air compressors on the market, rotary screw models are generally simple in design and relatively easy to maintain through many years of service life. Applications of screw compressors are as follows ; 1) Delivery capacity: from 200 to 20000 m3/hr 2) Pressure ratio: less than 3 bar in one stage and up to 12 to 14 bar in two stages. The entrapped gas is progressively compressed as it moves through the narrowing passage ways formed by the lobes. The two shafts are enclosed in an airtight casing. The principle for a rotating displacement compressor in twin screw form was developed during the 1930s, when a rotating compressor with a high flow rate and stable flow under varying pressure conditions was required. As it is a positive displacement machine, high-pressure refrigerants, such as R-22 and ammonia are used in it. The rotors and housing are manufactured with ultimate precision to minimize leakage from the pressure side to the inlet.

He also likes to write articles related to the mechanical engineering field and tries to motivate other mechanical engineering students by his innovative project ideas, design, models and videos. In a screw compressor one of the shafts is driving shaft and the other is driven shaft. The screw compressor combines many advantageous features of both centrifugal and compressors, along with some of its own. The reason behind this is that the efficiency of any compression process will be highest if it is carried out isothermally in comparison to adiabatically or polytropically.

The screw compressor is generally not equipped with valves and has no mechanical forces that cause unbalance. The build-in pressure ratio is limited by the limiting temperature difference between the inlet and the discharge. 2 As the main rotor turns, the air trapped in the ineterlobe space is moved both axially and radially. Rotors are forged from normal carbon steel and must dynamically balance after machining. rotary screw compressor units with microprocessor control all refrigerants this manual contains rigging, assembly, start-up, and maintenance instructions. The inlet and outlet flow from the compressor are neither radial as in the case of roots blower nor axial but oblique. Thus to maintain the temperature of air during compression, the heat developed is continuously exchanged with flowing water. Manual Stal Screw Compressor.pdf ... Stal compressors ? ​As you can see the shared area will be minimum for isothermal compression thus requiring minimum work for the compression process which will lend you higher efficiency. Rotary Screw Air Compressor Maintenance Guide. The male rotor (driving rotor) and consists of a series of lobes (usually four) along the length of the rotor that mesh with similarly formed corresponding helical flutes (usually six) on the female (driven rotor) rotor and a very small clearance between them. The air is compressed by direct volume reduction as the enmeshing of the lobes progressively reduced the flute volume and compression occurs. It may be considered as a vertical shaper. 2. The twin-screw element’s main parts are the male and female rotors, which rotate in opposite directions while the volume between them and the housing decreases. As the main rotor turns, the air trapped in the ineterlobe space is moved both axially and radially. As shown in Fig. Technical Manual VERSION 2.1 - 07-11-2019 3 1. with compressor technology. Hydraulic seals - Definition, Types, Diagram , Function, Failure, Application. External gears are most often used to synchronize the position of the counter-rotating rotors. At a fixed point where the leading edge of the flute and the edge of the discharge port co-inside, compression ceases and the air is discharged into the delivery line, until the flute volume has been reduced to zero. 22204929 Revision B May 2015 Save These Instructions SS3L3 Owner’s Manual with Parts List EN Owner’s Manual With Parts List ES Manual del propietario con la lista de piezas FR Manuel du propriétaire avec liste des pièces 62215.10.56 Stal screw compressors types 50, 70, 80, 24, 26 and R5.
