FAQs
Q1: What are the primary application areas for ammonia refrigerant compressors?
- Refrigeration and Air Conditioning: Ammonia compressors are widely used in industrial refrigeration systems, cold storage facilities, and large-scale air conditioning units. Ammonia's high latent heat of vaporization makes it an efficient refrigerant.
- Chemical Manufacturing: Ammonia is a key component in the production of fertilizers, plastics, explosives, and various chemical compounds. Ammonia compressors play a crucial role in maintaining the required pressure for these manufacturing processes.
- Cold Storage and Food Processing: Large cold storage facilities and food processing plants utilize ammonia compressors for efficient temperature control, ensuring the preservation of perishable goods.
Q2: How should routine maintenance and servicing of the ammonia refrigerant compressor be performed?
- Regular Inspections: Monitor parameters such as oil level, oil pressure, discharge pressure, discharge temperature, and motor current to ensure they remain within normal ranges.
- Filter and Oil Quality Checks: Periodically clean or replace suction and oil filters; test the refrigeration oil for acidity and water content, replacing it when necessary.
- Safety Valve and Protection Testing: Periodically calibrate protective devices-such as high/low-pressure controllers, safety valves, and oil pressure differential controllers-to ensure they operate reliably and responsively.
- Annual Overhaul: Based on operating hours, periodically disassemble the compressor to inspect internal clearances, bearings, and seals (including mechanical seals), and replace components showing signs of wear.
Q3: What pre-start checks are required for ammonia refrigerant compressors?
A comprehensive and systematic inspection must be conducted before startup to ensure the equipment operates safely and smoothly:
- Valve Status Check: Confirm that the suction and discharge shut-off valves are fully open to prevent overpressure accidents caused by starting the compressor with the valves closed.
- Oil Level and Temperature Verification: Check that the oil level in the sight glass is within the normal range; preheat the lubricating oil according to specifications during winter or when ambient temperatures are low.
- Safety Interlocks and Instrument Verification: Verify that high/low-pressure gauges, oil pressure differential switches, water flow switches, and all electrical protection and alarm interlock devices are properly connected and functional.
Q4: What are the common causes of excessively high discharge temperatures in ammonia compressors during operation?
- Excessive pressure ratio: Evaporation temperature is too low or condensing pressure is too high, causing the operating pressure ratio to exceed the design range.
- High suction temperature: Poor insulation on the suction line or excessive evaporator superheat.
- Insufficient cooling: For screw compressors or those with water-cooled jackets, low cooling water flow, high water temperature, or severe scaling on the water side prevents heat from being dissipated effectively.
- Lubrication issues: Insufficient oil supply, high oil temperature, or loss of oil viscosity prevents the effective removal of frictional heat generated during compression.
