본 발명은 입형 다단 펌프 공회전 방지 시스템에 관한 것으로서, 보다 상세 하게는 옥상이나 지하에 시설되는 급수 또는 배수 탱크의 수위를 검출하여 자동으로 급수 및 배수운전을 제어하는 장치이며, 특히 수위 및 온도를 감지하여 펌프를 구동 또는 정지시켜 공회전으로 인한 펌프의 손실을 방지할 수 있도록 구성되는 입형 다단 펌프 공회전 방지 시스템에 관한 것이다.The present invention relates to a vertical multi-stage pump idle prevention system, and more particularly, to detect the water level of the water supply or drainage tank installed on the roof or underground, and to automatically control the water supply and drainage operation. The present invention relates to a vertical multistage pump idling prevention system configured to prevent a pump loss due to idling by driving or stopping the pump.

일반적으로 정화조, 폐수, 오수, 물탱크에는 배수 또는 급수를 위한 다수개의 펌프가 설치되어 저수조의 수위에 따라 배수 또는 급수를 실시한다.In general, a plurality of pumps for drainage or water supply are installed in septic tanks, waste water, sewage, and water tanks to drain or supply water depending on the level of the reservoir.

특히, 물탱크 저수조의 수위를 원하는 바에 따라 적절하게 조절하기 위해 전극봉 또는 플로트 스위치를 이용한 수위검지부를 구비하게 되는데, 종래에는 설치된 각 펌프마다 수위 감지부가 설치되어 개별적으로 측정된 수위에 따라 펌프의 개별적인 동작이 이루어지도록 하였다.In particular, in order to properly adjust the water level of the water tank reservoir as desired, it is provided with a water level detection unit using an electrode or a float switch. In the related art, a water level detection unit is installed for each of the installed pumps, and according to the individual measured water level of the pump The operation was made.

즉, 종래에는 다수개의 펌프가 설치되었다고 가정할 경우, 그 펌프의 동작을 위한 수위가 각각 서로 다른 레벨로서 독립적으로 설정한 상태에서 그 설정된 동작수위에 저수량이 도달할 경우에만 펌프의 동작제어가 이루어지도록 하였으나, 상기와 같은 펌프의 동작 제어방식은 하나의 펌프가 설정된 동작수위에 따라 작동할 때, 상기의 펌프와 서로 다른 동작수위를 가진 펌프, 다시 말해 상기의 펌프보다 상위레벨의 동작수위에서만 동작하도록 설정된 펌프의 경우에는 동작이 전혀 이루어지지 않게 된다.That is, when a plurality of pumps are conventionally installed, the operation of the pump is controlled only when the water level reaches the set operation level while the level for the operation of the pump is independently set as a different level. However, the operation control method of the pump as described above, when one pump is operated according to the set operating level, the pump having a different operating level from the pump, that is, only operating at a higher level than the pump In the case of a pump that is set to do nothing, no action is taken.

또한, 종래에는 블류우트 펌프를 이용한 자동 급부 장치가 제안되어 풍부한 양수량을 얻을 수 있도록 하였지만, 급수 사용량이 빈번하게 변화되거나 압력탱크 내부의 공기가 누설되는 사례가 빈번하여 압력 스위치가 자주 단속되며 펌프의 모 터에는 압력 스위치가 온 되는 순간마다 과대한 가동시의 돌입전류가 흐르게 되어 모터가 과열로 인해 소손되는 경우가 발생할 뿐만 아니라, 급수원의 수위가 낮은 상태에서는 모터 및 펌프가 공회전하게 되고, 상기한 압력 스위치 역시 빈번한 작동으로 그 수명이 단축되어 고장률이 매우 높은 문제점이 있다.In addition, in the past, an automatic feeding device using a blowout pump was proposed to obtain abundant pumping amount. However, since the amount of water used frequently changes or the air inside the pressure tank leaks frequently, the pressure switch is often interrupted. When the pressure switch is turned on, the inrush current during excessive operation flows so that the motor is not burned out due to overheating, and the motor and pump are idling when the water supply level is low. One pressure switch also has a problem that the failure rate is very high due to its frequent operation.

한편, 액면 제어방식의 펌프를 이용한 자동급수장치는 충분한 용량의 급수 저장탱크를 제작, 설치해야만 하는 경제적인 부담이 있다.On the other hand, the automatic water supply device using a pump of the liquid level control system has an economic burden to manufacture and install a water supply storage tank of sufficient capacity.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로서, 본 발명은 모터 및 펌프가 공회전하는 현상을 보다 확실하게 방지하여 펌프의 소손을 미연에 예방할 수 있는 펌프의 공회전 운전방지장치를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, the present invention provides a pump to prevent the idle operation of the pump that can prevent the damage of the pump in advance to prevent the phenomenon that the motor and the pump idle more reliably. There is a purpose.

When the water level sensor 11 detects a low level, the signal area is separately installed in the control box. (Not shown) The signal is transmitted to the control unit, which is configured to electrically convert the signal to drive the pump 10 and to automatically supply water.

상기 하부 하우징(16)에 결합하는 온도감지센서(12)는 하부 소킷(18)에 결합된 상태로 고정되고, 상기 온도감지센서(12)가 감지하는 온도는 컨트롤 박스(미도시됨)의 제어부에 전달된다. 또한, 상기 하부 하우징(16) 내측에는 구동모터(13)의 회전력을 전달하는 샤프트(19)와 일체로 결합된 임펠러(20)를 형성하며, 이때 상기 임펠러(20)가 공회전하는 경우, 높은 온도가 하부 하우징(16) 내부에 발생하게 된다. 이러한 열은 전술한 바와 같이 하부 하우징(16)에 고정된 온도감지센서(12)에 의해 즉시 감지되게 되고, 상기 온도감지센서(12)가 감지하는 신호는 곧바로 제어부에 전달된 후, 전자변을 작동시켜 외부로 에어를 자동배출한다. The temperature sensor 12 coupled to the lower housing 16 is fixed in a state coupled to the lower socket 18, and the temperature detected by the temperature sensor 12 is a control unit of a control box (not shown). Is passed on. In addition, the lower housing 16 is formed inside the impeller 20 integrally coupled with the shaft 19 for transmitting the rotational force of the drive motor 13, wherein the impeller 20 when idling, high temperature Is generated in the lower housing 16. This heat is immediately detected by the temperature sensor 12 fixed to the lower housing 16 as described above, and the signal detected by the temperature sensor 12 is immediately transmitted to the control unit, and then operate the electronic valve. Air is automatically discharged to the outside.

즉, 펌프(10)를 이루고 있는 상부 하우징(15)과 하부 하우징(16)에는 수위를 감지하는 수위감지센서(11)와 온도를 감지하는 온도감지센서(12)를 각각으로 고정하여 저수위나 공회전시 펌프 내부 온도 상승을 미연에 방지할 수 있는 특징과 함께 온도 감지 후, 전자변을 통하여 에어를 효과적으로 제거할 수 있으며, 펌프의 공회전으로 인한 고장을 방지할 수 있어서 펌프의 수명을 장구히 할 수 있는 특징이 있다.That is, in the upper housing 15 and the lower housing 16 constituting the pump 10, the water level sensor 11 for detecting the water level and the temperature sensor 12 for sensing the temperature are fixed to each other to low water level or idling. It can prevent the rise of the internal temperature of the pump in advance, and it can effectively remove the air through the electronic valve after sensing the temperature, and can prevent the failure caused by idling of the pump, which can prolong the service life of the pump. There is a characteristic.

먼저, 메인 전원 스위치가 온 되면 전기적인 회로를 통하여 수위감지센서(11)에 전원이 인가된다. 이와 같이 전원이 공급되면 전원 공급이 컨트롤 박스(미도시됨)에 표시되고, 이때 사용자가 자동/수동 스위치를 선택적으로 자동 또는 수동 위치로 전환시켜 놓은 상태와 급수/배수 스위치를 배수 위치 또는 급수 위치로 전환시켜 놓은 상태에 따라 펌프의 자동적인 급수 운전과 배수운전, 수동적인 배수 운전이 실행된다. 또한, 급수/배수 스위치가 급수 위치로 전환되어 있는 상태에서 펌프 내의 수위가 저수위 센서 미만으로 내려가면 상부 하우징(15)에 형성된 수위감지센서(11)가 작동하여 제어부에 신호를 인가하게 된다.First, when the main power switch is turned on, power is applied to the water level sensor 11 through an electrical circuit. When the power is supplied in this way, the power supply is displayed in a control box (not shown), in which the user has selectively switched the automatic / manual switch to the automatic or manual position, and the water / drain switch is in the drain position Depending on the condition of switching to, the automatic water supply operation, the drain operation and the manual drain operation of the pump are executed. In addition, when the water level in the pump falls below the low water level sensor while the water supply / drainage switch is switched to the water supply position, the water level sensor 11 formed in the upper housing 15 operates to apply a signal to the controller.

이로써, 펌프(10)와 연결된 구동모터(13)는 회동하여 펌프(10)를 급수 운전하게 되는 것이다. 즉, 컨트롤 박스(미도시됨)에 형성된 제어부에 하이 신호가 가해지면 펌프(10)는 온 되므로 동작하여 스위치가 온 되고, 펌프(10)에 전원이 가해져서 펌프가 급수 운전을 하게 된다.As a result, the driving motor 13 connected to the pump 10 rotates to supply and operate the pump 10.

이상과 같이 상부 하우징(15)에 형성되는 수위감지센서(11)는 흡입 유량과 기 설정된 기준 흡입 유량을 비교하여 펌프의 운전 상태를 판단 후, 판단 결과에 따라 펌프의 구동을 제어할 수 있는 특징이 있다. 또한, 하부 하우징(16)에 형성된 온도감지센서(12)는 임펠러(20) 공회전시 상승하는 온도를 감지한 후, 전자변을 작동시켜 하부 하우징(16) 내부에 발생 되는 에어를 외부로 배출하는 특징이 있다.As described above, the water level detection sensor 11 formed in the upper housing 15 compares the suction flow rate with the preset reference suction flow rate, and after determining the operating state of the pump, can control the driving of the pump according to the determination result. There is this. In addition, the temperature sensor 12 formed in the lower housing 16 detects the temperature rising when the impeller 20 idles, and operates the electromagnetic valve to discharge air generated in the lower housing 16 to the outside. There is this.
