壓縮機之容調系統是利用油壓來控制，若溫度低，油粘度高；立即啟動壓縮機可能會使容調系統動作不順暢，故在系統運行前，需預加熱約8小時左右再開機。容調系統由一個容調滑塊、三個電磁閥及一組容調油壓活塞組成？烧{節的范圍有25%、50%、75%、100%。利用油壓活塞推動容調滑塊，壓縮機運轉時，油壓推動活塞，借助電磁閥的動作，控制油活塞的定位。而電磁閥則由系統的溫度來控制？刂迫菡{活塞的油系統從機殼的儲油槽中，以壓差的方式送入。經油過濾器后，用一支毛細管限流再送入油缸。若油過濾器阻塞或毛細管阻塞會造成容調動作失敗。同理，如果電磁閥故障，也會有同樣的情況發生。各容調電磁閥的得電失電情況見圖Compressor displacement regulating system is utilized to control the pressure, if the temperature is low, the high oil viscosity; immediately start the compressor may make a capacity adjusting system action is not smooth, so in the system operation, pre heating for about 8 hours and then boot. Capacity regulation system is composed of a capacitance adjustable slider, a three electromagnetic valve and a capacity adjusting hydraulic piston. The adjustable range of 25%,50%,75%,100%. Use of hydraulic piston pushes the capacity-regulating sliding block, the operation of the compressor, oil pressure to push the piston, by means of electromagnetic valve, oil control piston position. The electromagnetic valve is composed of the temperature control system. A control volume adjustable piston oil system from a storage tank, with pressure difference way into. Through the oil filter, a capillary restrictor and into cylinder. If the oil filter blocking or capillary occlusion can result in a capacity adjusting action failed. Similarly, if the solenoid valve failure, will have the same situation occurs. Each volume adjustable electromagnetic valve of power failure
