What causes oil pressure to fluctuate in a SABROE Compressor?
If the oil pressure fluctuates in the SABROE Compressor, make the necessary adjustments or corrections to address liquid injection overfeeding or refrigerant flood back from the system.
What to do if discharge pressure is excessively high in SABROE Compressor?
If the discharge pressure of the SABROE Compressor is excessively high, check the setting of alarms and warnings and the safety pressure cut-out. Inspect valves and check valves for high discharge line loss. Examine the condenser for proper functioning, ensuring adequate liquid drain, correct refrigerant charge, appropriate water/air inlet temperature, and sufficient water/air flow. Also, purge any air or non-condensable gasses from the condenser side.
Why is the suction pressure excessively low in my SABROE Compressor?
If the suction pressure of the SABROE Compressor is excessively low, reduce the compressor capacity if the refrigeration load is lower than the compressor capacity. Inspect valves and strainers for high suction line loss. Check the evaporator for fouling, accumulated oil, and proper function of the liquid expansion valve system. Also, check the filter in the liquid line and ensure the refrigerant charge is sufficient.
How to fix excessive noise and vibration in SABROE Compressor?
To address excessive noise and vibration in the SABROE Compressor, first, ensure the main oil injection valve is properly adjusted (not fully closed or too far open). Inspect for bearing damage or excessive wear and replace bearings if necessary. Verify the slide valve/slide stop calibration. Tighten the coupling on the shaft or replace it if damaged. Also, check for refrigerant flood back (liquid slugging) and correct any system issues causing it.
What to do if the capacity slide valve of SABROE Compressor will not move?
If the capacity slide valve and/or slide stop of your SABROE Compressor will not move, and you cannot unload/load, ensure that the oil pressure is sufficient. Replace any burned-out solenoid coils. Check the valve settings in the hydraulic system according to the hydraulic system description and inspect the 4-way control valve of slide components, following the description of the main components.
Why does my SABROE Compressor have high suction pressure but low refrigeration capacity?
If the SABROE Compressor has high suction pressure and insufficient refrigeration capacity, check the discharge pressure safety cut-out settings and inspect the pilot and main protection valve. Adjust the regulating valve according to the manual if the oil return valve is fully open. Clean the strainer if the suction strainer is clogged.
Why is grease leaking from the vent port of my SABROE Compressor pump?
If grease leaks from the vent port in the side of the SABROE Compressor pump body, this is normal leakage which will cease after initial operation. If leakage exceeds the normal allowable rate of 7 drops per minute, replace the seal.
What causes high oil temperature in SABROE Compressor and how to resolve it?
If the oil temperature is too high (and discharge temperature) in your SABROE Compressor, check that the valves in the oil system are fully open and inspect the opening position of the oil regulation valve. Verify the function of the 3-way oil temperature control valve and replace the sensor element if necessary. For water-cooled systems, check the oil cooler for fouling, water inlet temperature, and water flow. For refrigerant-cooled systems, check/drain accumulated oil in the oil cooler and ensure the gravity-fed refrigerant system is full flooded. For liquid injection systems, check the settings in the control system, as well as the valves and strainer in the liquid injection line. Finally, check the discharge pressure safety cut-out settings and inspect the pilot and main protection va...
What to do if oil filter differential pressure is too high in SABROE Compressor?
If the oil filter differential pressure is too high in the SABROE Compressor, replace the oil filter because it is likely clogged.
What causes low discharge temperature and oil foaming in SABROE Compressor?
If the discharge temperature of the SABROE Compressor is very low, the oil temperature is low, and oil may be foaming in the oil separator, check the evaporator (and economizer if equipped) and expansion valve function for excessive liquid in the suction line or liquid slugging. Decrease the rate of evaporator temperature 'pull down'. Also, check the settings in the control system (increase the set point) and the stability of the liquid injection if liquid injection is overfeeding.
