SAB 110
Description for compressor SAB 110
The SAB 110 is a screw compresor with oil injection and capacity regulating, from approx. 25% to 100%.
Existing types of SAB 110:
L/D | Form/types of coupling |
|
SAB110S | 1.2 | М |
SAB110L | 1.5 | М |
SAB110S | 1.2 | F |
SAB110L | 1.5 | F |
L/D indicates the ratio between the rotor lengths L and outer diameter D = 110 mm.
SAB 110 operates on either R717 or R22 refrigerants within the following operational limits:
Max. operational pressure: 25 bar
Max. differential pressure: 20 bar
Highest condensation temperature:
R717 +53°С
R22 + 55°С
Highest evaporation temperature:
R717 и R22 +15°С
Lowest evaporation temperature:
R717 и R22 -55°С
- The electric motor is flanged directly to compressor, thus ensuring alignment to the compressor. The motor will not be part of the refrigerant circuit as with semihermetic compressor types. In this way the compressor can also be used for R717.
The electric motor is coupled to the rotor by means of a flexible coupling which can be connected to either male rotor (coupling form M) or female rotor (coupling form F).
For each of the two types of coupling there are two rotor sets:
Type S with L/D = 1.2 or type L with L/D = 1.5 respectively, corresponding to a total of 4 rotor sets
Using female drive the compressor yields a 50% higher capacity and requires a correspondingly higher motor power than when using male drive. - The rotors are designed with a so-called D-profile acc. to SRM licence, and with a ratio of 4+6. This means that the male rotor has 4 profile lobes and the female rotor 6 ones.
At the suction end the rotors are provided with roller bearings, while the bearings at the discharge end consist of a combined set of roller bearings which assimilate the radial load, and ball-bearings assimilating the axial road. The axial forces are partly equalized by rotating balance pistons mounted on the rotors. - The compressor is equipped with a large built-in suction filter, effectively preventing dirt from the plant being carried along with the suction gas into the compressor. Further, the compressor has a combined suction pressure regulator and a non-return valve ensuring that the compressor always operates at a differential pressure between its discharge and suction side.
Hereby an effective lubrication of the compressor is secured both on start-up and during operation.
At the same time the suction pressure regulator acts as non- return valve, preventing the rotors from running in reverse when current to the drive motor is switched off. - The rotor shaft, to which the motor is connected is equipped with a shaft seal of the slide ring type. It consists of a stationary sealing ring, made of special carbon, fitted in the end cover of the compressor and sealed against same by means of an Oring.
Fastened to the rotor shaft and pressed against the carbon ring by a spring system. A rotating cast iron ring seals against the carbon ring. The shaft seal is of the balanced type, which means reduced slide surface pressure and consequently prolonged life. - The compressor capacity is regulated by means of the regulating slide valve underneath the rotors. When the regulating slide valve moves away from its end stop in its 100% position, capacity is reduced steplessly, as part of the suction gas, between rotors, is not compressed.
The regulating slide valve is moved by a piston which via two solenoid valves is activated by the oil pressure in the unit.
When in open position, one of the solenoid valves, closed at dead coil, adds oil pressure to the piston, hereby moving the regulating the slide valve towards a higher capacity.
The other solenoid valve, open at dead coil, carries, when open, oil from piston (cylinder) back to suction side of compressor. The result is that when the compressor is stopped and the two solenoid valves are dead, the regulating slide valve is moved to lowest capacity position by means of the built-in spring and the pressure behind the piston. In this way the compressor is unloaded before next start-up. - SAB 110 has a built-in regulating system by which the compressor volume ratio Vi can be adjusted manually. With the Vi-system the compression ratio of the compressor can be adjusted according to the plant pressures, before and after the compressor.
In this way over and under compression is avoided and the lowest possible energy consumption achieved. - КFurther, the SAB 110 compressor has a built-in combined oil filter which, by means of a filter cartridge retains all particles bigger than 10 micron, and a magnetic filter in which any small iron particles are collected.
In connection with filter housing a float valve is built in, ensuring a constant oil flow the to compressor.
Likewise, a built-in safety valve safeguards the compressor against unacceptably high differential pressures from discharge to suction side.
