HSO 2024 to HSO 2035 Installation, Operation and Maintenance Manual General Description The J & E Hall International HSO 2000 series of open drive compressors form part of the HallScrew family of positive displacement, oil injected, single screw compressors. These compressors have been specially developed for refrigeration, air conditioning and heat pump applications, and can be applied to single stage and multi-stage systems using all normal refrigerants as well as many other process gases.
HSO 2024 to HSO 2035 Installation, Operation and Maintenance Manual The main rotor and star rotors are housed inside a one-piece, cast-iron main casing. The inside of the casing has a somewhat complex shape, but essentially consists of a cylindrical annulus which encloses the main rotor leaving a small clearance.
Page 15
HSO 2024 to HSO 2035 Installation, Operation and Maintenance Manual The movement of the slide valves is effected by oil pressure acting on a piston which is connected to the valves by a yoke. Pressurised oil is taken from the lubrication system and fed through solenoid valves which respond to signals from the plant control system.
HSO 2024 to HSO 2035 Installation, Operation and Maintenance Manual 1. S UCTION 2. S UCTION Fig 1 Compression Process 3.4. The Compression Process As the HallScrew is a positive displacement compressor, there are three separate stages in the compression cycle: suction, compression and discharge.
HSO 2024 to HSO 2035 Installation, Operation and Maintenance Manual 3. C OMPRESSION 4. D ISCHARGE Fig 1 (continued) Compression Process 3.4.2. Compression As the main rotor turns, the volume of gas trapped within the flute is reduced as the length of the flute shortens and compression occurs. 3.4.3.
HSO 2024 to HSO 2035 Installation, Operation and Maintenance Manual Capacity Control and Volume Ratio Since the HallScrew compressor utilises fixed intake and discharge ports instead of valves, the overall compression ratio is determined by the configuration of these ports. The degree of compression is governed by the ratio between the flute volume when it is sealed off by the star tooth at the beginning of the compression process, to that immediately before the delivery port is uncovered.
HSO 2024 to HSO 2035 Installation, Operation and Maintenance Manual The best part load characteristics are achieved if the design full load V maintained as the compressor’s capacity is reduced. The HallScrew 2000 series compressor is fitted with a pair of sliding valves, one for each half of the symmetrical compression process.
HSO 2024 to HSO 2035 Installation, Operation and Maintenance Manual 4.2. Capacity Control Solenoid Valve Arrangements As discussed in 7. Oil Circulation, if the system suction/discharge pressure differential is sufficient to generate oil pressure for injection and lubrication, an oil circulation pump can be dispensed with altogether. However, as there is no other oil pressure source, special precautions must be taken to automatically return the capacity control piston to the minimum load position when the compressor stops to provide a...
HSO 2024 to HSO 2035 Installation, Operation and Maintenance Manual 4.3.4. Flow Control Valves The capacity control piston and slide valves speed of travel, and hence how quickly the compressor loads and unloads, is determined by flow control valves fitted in the load and unload oil lines to the capacity control cylinder.

HSO 2024 to HSO 2035 Installation, Operation and Maintenance Manual 4.5. Capacity Control by Inverter Drive Instead of using the slide valves, compressor capacity can be controlled using a frequency inverter (also known as Variable Speed Drive or Variable Frequency Drive). If an inverter is used, the load/unload solenoid valves need to be controlled to allow the compressor to start at minimum load but load to full load when the compressor is running.
HSO 2024 to HSO 2035 Installation, Operation and Maintenance Manual 4.6. Linear Variable Displacement Transducer (LVDT) The LVDT provides a continuous 4 to 20 mA slide valve position signal between minimum load (25 %) and maximum load (100 %). The LVDT operates on the principle of using a coil (inductance element) to produce an electrical output proportional to the displacement of a separate movable indicator rod.

HSO 2024 to HSO 2035 Installation, Operation and Maintenance Manual Compressor Lubrication, Sealing and Cooling In common with other types of oil injected screw compressor, HSO 2000 series compressors do not possess a built-in oil reservoir (sump), oil circulation pump or oil filtration equipment. Instead, oil is supplied by a separate external oil support system.
Page 33
HSO 2024 to HSO 2035 Installation, Operation and Maintenance Manual Positioning the oil injection ports in the capacity control slide valves ensures that, at all slide valve positions, oil enters the main rotor flutes after the flute volume has been sealed, i.e. oil injection always occurs during the compression process over the whole capacity control range, thus ensuring maximum pumping efficiency.
HSO 2024 to HSO 2035 Installation, Operation and Maintenance Manual Oil Support System HSO 2000 series compressors require an external oil separator and oil support system; refer to Appendix 2 Oil Support System Schematic Flow Diagrams. NOTE: the system into which the compressor is to be installed must fully comply with the recommendations in 6.1.
HSO 2024 to HSO 2035 Installation, Operation and Maintenance Manual 6.3. Oil Separation All the oil injected into the compressor for lubrication, sealing and capacity control actuation, ultimately ends up in the discharge gas stream. During its passage through the compressor the oil is thoroughly mixed with the refrigerant, eventually ending up in the discharge gas stream as a fine mist of oil droplets.
HSO 2024 to HSO 2035 Installation, Operation and Maintenance Manual 6.4.1. Oil Return As already mentioned in 6.2, the separator must be positioned at a suitable height such that the standing oil level (compressor stopped) is significantly below the bottom of the compressor. For applications using a continuously running oil pump a drain line must be installed between the compressor casing and the oil separator.
HSO 2024 to HSO 2035 Installation, Operation and Maintenance Manual Oil Circulation An oil circulation pump can be dispensed with for most operating conditions using HSO 2000 series compressors or if a pump is necessary it is only required to run at start-up. For applications without an oil pump, oil circulation is maintained by the pressure difference generated between the high pressure side of the system and the pressure in the sealed main rotor flute at the point of oil...
