A liquid oil replacing machine comprises a liquid storage tank, a pumping and injecting assembly, a liquid level sensor and a controller, the liquid storage tank is used for containing liquid oil, the pumping and injecting assembly is connected with the liquid storage tank and used for pumping and injecting the liquid oil in the liquid storage tank into an external liquid storage kettle, the liquid level sensor is electrically connected with the liquid storage tank, the controller is electrically connected with the pumping and injecting assembly and the liquid level sensor, the liquid level sensor is used for detecting the liquid level of the liquid oil in the liquid storage tank and feeding back the liquid level to the controller, and the controller is used for sending a control instruction to the pumping and injecting assembly when the liquid oil in the liquid storage tank descends to a first preset height, so that the pumping and injecting assembly continues to run accumulatively for a first preset time and then stops running, the liquid level of the liquid oil in the liquid storage tank is reduced from the first preset height to the second preset height, and the second preset height is higher than the height of the inner bottom surface of the liquid storage tank. More liquid oil in the liquid storage tank can be conveyed into the external liquid storage kettle, so that the utilization rate of the liquid oil is increased, and waste of the liquid oil is reduced.

    一种液油更换机包括储液罐、抽注组件、液位传感器及控制器,储液罐用于盛放液油,抽注组件与储液罐连接,抽注组件用于将储液罐内的液油抽注到外部的储液壶内,液位传感器与储液罐电连接,控制器与抽注组件及液位传感器电连接,液位传感器用于检测储液罐内的液油的液面高度并反馈给控制器,控制器用于在储液罐内的液油下降至第一预设高度时向抽注组件发出控制指令,以使抽注组件继续累计运行第一预设时间后停止运行,从而以使储液罐内的液油的液面高度由第一预设高度下降至第二预设高度,第二预设高度高于储液罐的内底面所处的高度,本申请能够将储液罐内更多地液油传输到外部的储液壶内,从而提高了对液油的利用率,减少了对液油的浪费。
