压缩机之容调系统是利用油压来控制，若温度低，油粘度高；立即启动压缩机可能会使容调系统动作不顺畅，故在系统运行前，需预加热约8小时左右再开机。容调系统由一个容调滑块、三个电磁阀及一组容调油压活塞组成。可调节的范围有25%、50%、75%、100%。利用油压活塞推动容调滑块，压缩机运转时，油压推动活塞，借助电磁阀的动作，控制油活塞的定位。而电磁阀则由系统的温度来控制。控制容调活塞的油系统从机壳的储油槽中，以压差的方式送入。经油过滤器后，用一支毛细管限流再送入油缸。若油过滤器阻塞或毛细管阻塞会造成容调动作失败。同理，如果电磁阀故障，也会有同样的情况发生。各容调电磁阀的得电失电情况见图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
