Repair and maintenance of GEA screw compressor unit GRASSO SP1 due to low suction pressure issue

Thread Content

Repair and maintenance for the low suction pressure fault of the GEA screw compressor unit GRASSO SP1: The screw compressor unit consists of a refrigeration system that is used to compress refrigerants such as ammonia and R22 (other refrigerants like R134a, R404a, R507, etc., depending on requirements). The components can be used as heat pumps. Reasons: 1. Loss of refrigerant due to leaks in the refrigerant circulation system; 2. Damaged pressure sensor; 3. Fault in compressor power regulation; 4. Clogged suction filter. Repair measures: 1. Check for leaks in the complete set of equipment. Rule out leaks; replenish refrigerant if possible: 2. Replace the pressure sensor: 3. Check the power regulator, especially the solenoid valve connections: 4. Clean or replace the filter element. Maintenance of GEA screw compressors GRASSO SP1
