Presentation Transcript

  1. TT-011-0808 The compressor

  2. Contents • The refrigerant compressor • Internally controlled compressor • Magnetic coupling • Externally regulated compressor • Overload protection

  3. The refrigerant compressor • Swash plate compressor with electromagnetic coupling F208_027 Video "Initial operation"

  4. Internally controlled compressor • With electromagnetic coupling Drive F208_047

  5. Internally controlled compressor • Overview Swash plate Regulating valve Guide rail Calibratedrestrictor hole Drive shaft High pressure Low pressure Upper side Lower side F208_047 Springs Drive hub Piston Chamber pressure

  6. Internally controlled compressor • Swash plate adjustment increases Bellows 2 Bellows 1 Regulating valve Chamber pressure Chamber pressure Restrictor hole F208_048 Spring 1 Spring 2 High pressure Low pressure

  7. Internally controlled compressor • Swash plate adjustment decreases Bellows 2 Bellows 1 Regulating valve Chamber pressure Chamber pressure Restrictor hole F208_049 Spring 2 Spring 1 High pressure Low pressure

  8. Magnetic coupling • Overview Diagram showing coupling switched off Diagram showing coupling switched on Belt pulley with bearing Compressor drive shaft Spring plate with hub Compressor housing Solenoid coil F208_002 F208_003 Flow of power

  9. Externally regulated compressor • Overview Compressor regulator valve N280 Belt pulley with rubber moulding – overload protection

  10. Externally regulated compressor • Maximum delivery of swash plate Hollow piston Compression chamber Swash plate Control valve N280 Crankcase pressure High pressure Suction pressure F240_012 Drive shaft Suction side Crankcase Return spring High pressure side

  11. Externally regulated compressor • Zero delivery of swash plate F240_011

  12. Externally regulated compressor • A Crankcase pressureB High pressureC Low pressure • Direction of full load –A to B separated • Direction of no load –A to B opened • C restricts control valve depending on low pressure. • Compressor regulator valve N280 1 –Electromagnetic components 2 – Mechanical components

  13. Overload protection • Overview Belt pulley Rubber moulding Drive shaft Belt pulley Drive plate Rubber moulding F263_076

  14. Overload protection • Drive blocked Deformation of blockage Rubber moulding Severed material Blocked drive plate Rubber moulding F263_077 Severed material
