    • PURPOSE: An apparatus for controlling operation of a reciprocating compressor, and a method thereof to secure the maximum compression volume of the compressor by increasing stroke by applying alternating and direct voltage are provided to improve the operation efficiency of a compressor. CONSTITUTION: A stroke detector(200) detects a piston stroke distance of a compressor as stroke. A comparator(300) compares the stroke output from the stroke detector with a stroke command value for outputting a difference signal. A direction voltage command value generator(100) detects temperatures of a suction port and a discharge port of the compressor as load and generates a direct voltage command value if the load corresponds to a load condition. A controller(400) controls stroke by varying an alternating voltage applied to the compressor. If receiving the direct voltage command value, the controller applies a direct voltage and an alternating voltage variable according to the load to the compressor for increasing stroke.
    • 目的:提供一种用于控制往复式压缩机的操作的装置及其通过施加交流和直流电压来增加行程来确保压缩机的最大压缩体积的方法,以提高压缩机的运行效率。 构成:行程检测器(200)检测压缩机的活塞行程距离作为行程。 比较器(300)将来自行程检测器的行程输出与用于输出差分信号的行程指令值进行比较。 方向电压指令值发生器(100)将压缩机的吸入口和排出口的温度作为负载进行检测,并且如果负载对应于负载条件,则产生直流电压指令值。 控制器(400)通过改变施加到压缩机的交流电压来控制行程。 如果接收到直流电压指令值,则控制器根据负载将直流电压和交流电压变量加到压缩机上以增加行程。

    • PURPOSE: A method and device for controlling an electronic water pump is provided to optimally maintain the cooling performance of an engine by operating the electronic water pump according to a state of the engine, a control condition, and a load condition. CONSTITUTION: A device for controlling an electronic water pump comprises a thermostat(110), a radiator(120), a water temperature sensor(130), an electronic water pump(140), and a controller(150). The thermostat determines a circulation direction according to the temperature of coolants. The radiator radiates heat absorbed in the coolants by expanding a contact area between the coolants and atmosphere through a core. The water temperature sensor detects the temperature of the coolants. The electronic water pump is inserted between an engine(100) and the thermostat, and a driving speed of the electronic water pump is controlled. The controller determines and controls the driving speed of the water pump by applying RPM and the mount of fuel and a correction coefficient according to the temperature of the coolants.
    • 目的:提供一种用于控制电子水泵的方法和装置,以通过根据发动机的状态,控制条件和负载条件操作电动水泵来最佳地保持发动机的冷却性能。 构成:用于控制电子水泵的装置包括恒温器(110),散热器(120),水温传感器(130),电子水泵(140)和控制器(150)。 恒温器根据冷却液的温度决定循环方向。 散热器通过一个核心扩大冷却剂和大气之间的接触面积,从而辐射吸收在冷却剂中的热量。 水温传感器检测冷却液的温度。 电子水泵插入在发动机(100)和恒温器之间,并控制电子水泵的驱动速度。 控制器通过施加RPM和燃料的安装来确定和控制水泵的驱动速度,并根据冷却剂的温度来校正系数。
