Claims (6)

펌프의 내부압력을 대략 선형으로 검출할 수 있는 압력센서를 구비하고, 이 압력센서로부터의 정보가 있으면 압력치가 표시되고, 상기 압력센서로부터의 정보가 없으면 압력센서회로의 비정상 동작을 경고하는 신호가 표시되는 것을 특징으로 하는 펌프장치.A pressure sensor capable of detecting the internal pressure of the pump in a substantially linear manner, the pressure value is displayed if there is information from the pressure sensor, and if there is no information from the pressure sensor, a signal warning the abnormal operation of the pressure sensor circuit Pump apparatus, characterized in that displayed. 펌프의 내부압력을 대략선형으로 검출할 수 있는 압력센서와, 펌프장치의 동작상태를 모터를 통해 흐르는 전류를 검출할 수 있는 전류센서를 구비하고, 상기 전류로부터의 정보에 의해 펌프의 정상동작이 확인되는 경우, 정상동작을 나타내는 압력치로부터 비정상 동작을 알리는 신호로 표시가 전환되며, 이와 동시에 정상동작에 대한 한정된 상한 압력치보다 높은 펌프압력치가 상기 압력센서에 의해 검출되는 것을 특징으로 하는 펌프장치.And a pressure sensor capable of detecting the internal pressure of the pump in a substantially linear form, and a current sensor capable of detecting a current flowing through the motor in an operating state of the pump device. If confirmed, the display is switched from a pressure value indicating normal operation to a signal indicating abnormal operation, and at the same time a pump pressure value higher than the limited upper limit pressure value for normal operation is detected by the pressure sensor. . 제2항에 있어서, 사기 압력치와 비정상 동작을 나타내는 상기 신호가 동시에 표시되는 것을 특징으로 하는 펌프장치.The pump apparatus as claimed in claim 2, wherein the fraud pressure value and the signal indicating abnormal operation are simultaneously displayed. 제2항에 있어서, 상기 전류로부터의 정보에 의해 펌프의 정상동작이 확인되는 경우, 정상동작을 나타내는 압력치로부터 비정상 동작을 알리는 신호로 표시가 전환되며, 이와 동시에 정상동작에 대해 한정된 하한 압력치보다 낮은 펌프압력치가 상기 압력센서에 의해 검출되는 것을 특징으로 하는 펌프장치.3. When the normal operation of the pump is confirmed by the information from the current, the display is switched from the pressure value indicating the normal operation to the signal indicating the abnormal operation, and at the same time, the lower limit pressure value defined for the normal operation. A lower pump pressure value is detected by said pressure sensor. 제2항에 있어서, 비정상 동작을 나타내는 신호가 표시된 후 동일한 압력치가 소정시간동안 연속적으로 검출되면 펌프장치의 동작이 강제로 정지되는 것을 특징으로 하는 펌프장치.The pump device according to claim 2, wherein the pump device is forcibly stopped when the same pressure value is continuously detected for a predetermined time after a signal indicating abnormal operation is displayed. 제2항에 있어서, 펌프장치는 교대로 또는 동시에 동작하는 2개의 펌프헤드를 포함하고, 하나의 펌프헤드에 대해 비정상 동작을 나타내는 신호가 표시된 후 동일한 압력치가 소정시간동안 연속으로 검출되면 그 하나의 펌프헤드가 정지되고, 다른 정상의 펌프헤드가 자동으로 동작기동되는 것을 특징으로 하는 펌프장치.The pump device according to claim 2, wherein the pump device includes two pump heads operating alternately or simultaneously, and if the same pressure value is continuously detected for a predetermined time after a signal indicating abnormal operation is displayed for one pump head, A pump device, characterized in that the pump head is stopped and another normal pump head is automatically started. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
