Accordingly, in recent years, there has been an increasing demand for the pump to be operated automatically under the optimal operating conditions even if only the flow value (flow rate) required by the pump is input. In particular, However, there is no specific control method for controlling the control method.

도 1은 본 발명의 실시예에 따른 선박용 유압오일펌프(500)의 오일 디스차징 자동 제어시스템을 도시한 것이다. 도 1을 참조하면, 본 발명의 일측면에 따르면 사용자가 플로우값을 입력하면, 토탈헤드제어부(DPIC, 200)와 디스차지압력제어부(PIC, 300)의 셋포인트를 결정하는 플로우인디케이션제어부(FIC, 100), 상기 플로우인디케이션제어부(FIC, 100)에 의하여 결정된 셋포인트에 따라 펌프(500)의 토탈헤드를 제어하는 토탈헤드제어부(DPIC, 200); 및 상기 플로우인디케이션제어부(FIC, 100)에 의하여 결정된 셋포인트에 따라 펌프(500)의 디스차지압력을 제어하는 디스차지압력제어부(PIC, 300)를 포함하는 유압오일펌프(500)의 오일 디스차징 자동제어시스템이 제공될 수 있다. 또한, 펌프(500)의 석션 압력을 계산하여 상기 디스차지압력제어부(PIC, 300)로 공정값을 보내는 압력인디케이션(PI)을 더 포함할 수 있으며, 상기 디스차지압력제어부(PIC, 300)는 펌프(500)와 연결되는 컨트롤밸브(400)를 개폐하며 디스차지압력을 제어하는 것을 특징으로 할 수 있다. FIG. 1 illustrates an oil dispensing automatic control system for a marine hydraulic oil pump 500 according to an embodiment of the present invention. 1, according to an aspect of the present invention, when a user inputs a flow value, a flow indication control unit (DPIC) 200 and a flow indication control unit (PIC) 300 for determining a set point of a discharge pressure control unit A total head controller (DPIC) 200 for controlling the total head of the pump 500 according to the set point determined by the flow indication controller (FIC) 100; And a discharge pressure control unit (PIC) 300 for controlling the discharge pressure of the pump 500 according to the set point determined by the flow indication control unit (FIC) 100, A charging automatic control system can be provided. The discharge pressure controller (PIC) 300 may further include a pressure indicator (PI) for calculating a suction pressure of the pump 500 and sending a process value to the discharge pressure controller PIC 300. The controller 500 controls the discharge pressure by opening / closing the control valve 400 connected to the pump 500.

구체적인 동작을 살펴보면, 공정의 압력손실이 많을 경우 일단, 컨트롤밸브(400)가 100% 열려, 시스템의 압력 감소(pressure drop)을 최소로 하고, hydraulic oil 압력을 점진 적으로 높여, 작업자(operator)가 입력한 플로우 셋포인트(flow set point)를 만족하게 한다. The control valve 400 is opened by 100% to minimize the pressure drop of the system and gradually increase the hydraulic oil pressure so as to allow the operator to operate the control valve 400. [ To satisfy the flow set point inputted by the user.

즉, 입력한 플로우값에 따라, 먼저 컨트롤밸브(400)가 작동이 되면, pump discharge valve가 100% 열려도 유량이 셋포인트에 미치지 않을 경우 hydraulic oil 압력을 높여, 펌프(500)의 shaft power 높여 궁극적으로 펌프(500) 회전 속도를 높여 공정에서 요구 하는 해당 유량에 맞는 펌프(500) 디스차지 압력으로 맞쳐 주는 것이다. That is, according to the input flow value, if the control valve 400 is operated first, if the flow rate is not equal to the set point even if the pump discharge valve is opened 100%, the hydraulic oil pressure is increased and the shaft power of the pump 500 is increased Ultimately raising the rotational speed of the pump 500 to match the discharge pressure of the pump 500 corresponding to the flow rate required in the process.

구체적으로 플로우인디케이션제어부(FIC, 100)에서는 먼저 작업자가 플로우값을 입력하면 토탈헤드제어부(DPIC, 200)와 디스차지압력제어부(PIC, 300)의 셋포인트를 결정하고Specifically, the flow indication controller (FIC) 100 first determines a set point of the total head controller (DPIC) 200 and the discharge pressure controller (PIC) 300 when an operator inputs a flow value

일단 결정된, 토탈헤드제어부(DPIC, 200)와 디스차지압력제어부(PIC, 300)의 셋포인트에 따라, 컨트롤밸브(400)는 토탈헤드제어부(DPIC, 200)의 셋포인트를 맞쳐 주기 위해 제어된다.The control valve 400 is controlled to match the set point of the total head controller DPIC 200 according to the set point of the total head controller DPIC 200 and the discharge pressure controller PIC 300 once determined .

만약 토탈헤드제어부(DPIC, 200)의 셋포인트가 낮을 경우, 컨트롤밸브(400)는 100%열리기된다. If the set point of the total head control unit (DPIC) 200 is low, the control valve 400 is opened 100%.

그리고 플로우인디케이션제어부(FIC, 100)의 출력이 유량을 만족하게 하기위해 계속 증가할 경우 토탈헤드제어부(DPIC, 200)의 셋포인트는 최소로 하고, 디스차지압력제어부(PIC, 300)의 셋포인트를 증가하게 한다. When the output of the flow indication control unit FIC 100 continues to increase to satisfy the flow rate, the set point of the total head control unit DPIC 200 is set to a minimum and the set point of the discharge pressure control unit PIC 300 Increase points.

따라서 디스차지압력제어부(PIC, 300)의 셋포인트가 증가하여 공정에서 요구하는 해당 유량의 압력 손실을 보상하게 됨으로 유량을 제어 할 수 있게 되는 것이다. Therefore, the set point of the discharge pressure control unit (PIC) 300 increases, and the pressure loss of the corresponding flow rate required in the process is compensated, so that the flow rate can be controlled.

토탈헤드제어부(DPIC, 200)의 역할은 공정의 압력 손실인 낮을 경우, hydraulic oil 압력이 너무 낮아져서 펌프(500)의 터빈에 비정상적이 동작 조건(operation condition)을 방지하기 위하여, discharge control valve의 개도를 줄여, 궁극적으로 공정의 압력 손실을 증가 시켜 펌프(500) 터빈에 걸리는 hydraulic oil 압력이 과도하게 낮아지는 것을 방지하고 펌프(500)를 적정 회전수(minimum allowable pump speed) 아래로 내려가는 것을 방지한다.The total head control unit DPIC 200 plays a role of controlling the opening degree of the discharge control valve in order to prevent abnormal operation conditions in the turbine of the pump 500 due to the hydraulic oil pressure being too low, To ultimately increase the pressure loss of the process to prevent excessive hydraulic oil pressure on the turbine of the pump 500 and prevent the pump 500 from falling below the minimum allowable pump speed .
