본 발명은 고압수 펌프의 흡입력 증강장치에 관한 것으로, 특히 제트펌프와 보조 흡입장치를 이용하여 자체 흡입력으로 흡입할 수 없는 깊은 곳의 물을 자체 펌프에서 발생하는 고압수의 일부를 이용하여 제트펌프를 가동하고, 제트펌프에서 흡입력을 증가시킴으로써, 별도의 급수펌프나 펌프 구동동력 및 물 탱크 등의 부품없이도 높은 수준의 흡입력을 갖도록 한 고압수 펌프의 흡입력 증강장치에 관한 것이다.The present invention relates to a suction power enhancer of a high pressure water pump, and in particular, a jet pump using a part of the high pressure water generated in a self pump for deep water that cannot be sucked by its own suction power using a jet pump and an auxiliary suction device. By operating and increasing the suction power in the jet pump, the suction power enhancer of the high-pressure water pump to have a high level of suction power without a separate feed pump or pump driving power and parts such as a water tank.

일반적으로 고압수 펌프(이하 '고압펌프'라 함)는 일반 양수펌프에 비하여 흡입력이 현저히 약하다. 이런 단점을 보완하기 위하여 도 1 에 도시된 바와 같이, 종래의 고압펌프(2)는 흡입부에 급수 펌프라인을 연결하여 강제급수를 하거나 별도 급수펌프(7)로 물탱크(8)에 물을 품어 올려 저장한 후, 물탱크(8)로부터 물을 흡입하여 펌핑하는 방식을 채용하고 있다.In general, the high pressure water pump (hereinafter referred to as 'high pressure pump') has a significantly weaker suction force than the general pump. In order to compensate for this disadvantage, as shown in Figure 1, the conventional high pressure pump (2) is connected to the feed water pump line to the suction portion for forced water supply or a separate water feed pump (7) to supply water to the water tank (8) After incubation, the water is sucked from the water tank 8 and pumped.

또한 고압펌프는 일반적으로 플란저 펌프 형식이 대부분이며 토출압력이 높은 데 반하여, 흡입력이 일반 양수펌프에 비하여 현저히 약하다.In addition, the high pressure pump is generally the type of plunger pump and the discharge pressure is high, while the suction power is significantly weaker than the general pump pump.

종래의 고압수 펌프 구조를 도시한 도 1 에서와 같이,고압펌프(2)의 자체흡입력으로 깊은데서 물을 흡입하기가 실질적으로 어려우며, 별도의 물탱크(8)와, 상기 물탱크(8)측으로 물을 끌어올리기 위한 급수펌프(7)를 별도로 설치해야 하므로, 필요 이상의 비용이 발생하고, 점유공간이 많아 비효율적인 문제점이 있다.As shown in FIG. 1, which shows a conventional high pressure water pump structure, it is substantially difficult to inhale water deep into the self suction input of the high pressure pump 2, and a separate water tank 8 and the water tank 8 are provided. Since a separate water feed pump (7) for raising water to the side is required, there is more cost than necessary, there is a lot of occupied space, there is an inefficient problem.

또한, 고압펌프의 자체 흡입력에 의해 흡입이 이루어지더라도 낙차가 어느 범위를 벗어나면 펌프 흡입량이 부족하여 토출압력이 낮아지고 펌프 내 손상을 주게되는 문제점이 있다.In addition, even if the suction is made by the suction pressure of the high-pressure pump, if the drop is out of a certain range, there is a problem that the pump suction amount is insufficient, the discharge pressure is lowered and damage in the pump.

따라서 본 발명은 상기한 종래의 문제점을 해결하기 위한 것으로, 고압펌프 자체에서 발생되는 고압수의 일부를 이용하여 제트펌프를 작동시키고, 제트펌프에서 펌프 흡입력을 증대시켜 줌으로써 고압펌프의 흡입력 약소에 따른 문제점을 별도의 동력 및 장소 등의 제공없이 해결할 수 있는 고압수 펌프의 흡입력 증강장치를 제공하는 것을 목적으로 한다.Therefore, the present invention is to solve the above-mentioned conventional problems, by operating the jet pump using a part of the high pressure water generated in the high pressure pump itself, by increasing the pump suction power in the jet pump according to the weak suction power of the high pressure pump It is an object of the present invention to provide a suction power enhancer of a high pressure water pump that can solve the problem without providing a separate power and place.

The jet pump unit 35 for supplying water, the first discharge hose 34 through which the water is injected to the nozzle gun side through the high pressure pump 32, and the predetermined water is branched from the discharge hose to the jet pump unit side. It consists of a configuration including a second discharge hose 34 to be drawn in.

상기 구성에서, 본 발명의 제트펌프부(35)는 제트펌프(35a)와 풋 밸브(35b)가 함께 결합되어 있으며, 그 하부에는 흡입망(37)이 결착된 구조를 이룬다.In the above configuration, the jet pump unit 35 of the present invention is coupled to the jet pump 35a and the foot valve 35b, the lower portion forms a structure in which the suction network 37 is bound.

본 발명 상기 고압펌프(32) 전방의 펌프 흡입부(36)는 도 2c 에 그 구조가 상세히 도시되어 있는 바와 같이, 흡입호스(33)와 고압펌프(32)가 연결되는 부위에 보조 흡입장치(40)가 구비되어 있다.The pump suction part 36 in front of the high pressure pump 32 of the present invention has an auxiliary suction device at a portion where the suction hose 33 and the high pressure pump 32 are connected, as shown in FIG. 2C. 40).

상기 보조 흡입장치(40)는 보조 물탱크(41)와, 상기 보조 물탱크(41)에 일단이 침지되고 타단은 상기 흡입호스(33)측으로 연결되는 보조 연결호스(43)와, 상기 보조 연결호스와 상기 흡입호스(33)가 연결되는 부위에 보조 흡입밸브(45)를 포함하는 구성으로 이루어지고 있다.The auxiliary suction device 40 has an auxiliary water tank 41, an auxiliary connection hose 43 having one end immersed in the auxiliary water tank 41 and the other end connected to the suction hose 33 side, and the auxiliary connection. It consists of a configuration including an auxiliary suction valve 45 in a portion where the hose and the suction hose 33 is connected.

상기와 같은 구성으로 된 본 발명의 고압수 펌프의 흡입력 증강장치의 작동에 대해 이하에서 설명하기로 한다.The operation of the suction power increasing device of the high pressure water pump of the present invention having the above configuration will be described below.

통상, 고압펌프 시스템에서는 초기에 제트펌프(35)를 가동시킬 고압수가 필요하게 되므로, 먼저 보조흡입장치(40)의 흡입밸브(45)를 열고 보조 흡입망(46)을 보조 물탱크(41)에 잠기도록 한다. 이때 보조 물탱크(41)를 가능한 보조 흡입망(46)의 가까운 곳에서 위치하도록 하여 초기흡입이 용이하게 되도록 한다.In general, in the high pressure pump system, since high pressure water is required to operate the jet pump 35 at first, the suction valve 45 of the auxiliary suction device 40 is first opened, and the auxiliary suction network 46 is connected to the auxiliary water tank 41. To be locked. At this time, the auxiliary water tank 41 is positioned as close to the auxiliary suction network 46 as possible to facilitate initial suction.

다음, 고압펌프(32)를 작동하여 보조 흡입장치(40)로부터 고압펌프(32) 측으로 물이 흡입되도록 하고, 다시 고압펌프(32)에서 압축하여 제트펌프부(35) 측으로 보낸다.Next, the high pressure pump 32 is operated so that water is sucked from the auxiliary suction device 40 toward the high pressure pump 32, and is compressed again by the high pressure pump 32 to be sent to the jet pump part 35.

제트펌프(35a)가 작동되면 주 흡입장치로부터 물을 흡입할 수 있게 된다. 주 흡입장치로부터 물이 원활하게 흡입되면, 보조 흡입장치(40)의 흡입밸브(45)를 막아도 주 흡입장치에서 물을 끌어 올릴 수 있게 된다.When the jet pump 35a is operated, water can be sucked from the main suction device. When water is smoothly sucked from the main suction device, even if the suction valve 45 of the auxiliary suction device 40 is blocked, the water can be pulled up from the main suction device.

상기한 본 발명의 고압수 펌프의 흡입력 증강장치에서는, 특히 제트펌프(35a)와 풋 밸브(35b)를 일체화함으로써, 물이 역류하지 않고 초기흡입을 효율적으로 할 수 있도록 하고 있으며, 펌프의 언로딩(Unloading) 후 재 로딩(Reloading)시 보조 흡입장치(40)의 가동을 필요 없게 해준다.In the suction force increasing device of the high-pressure water pump of the present invention described above, in particular, by integrating the jet pump 35a and the foot valve 35b, it is possible to efficiently perform the initial suction without backflow of the pump, and to unload the pump. Reloading after unloading eliminates the need to operate the auxiliary suction device 40.

이상에서 설명한 바와 같이, 본 발명에 따른 고압수 펌프의 흡입력 증강장치는 자체 흡입력으로 흡입할 수 없는 깊은 곳의 물을 자체 펌프에서 발생하는 고압수의 일부를 이용하여 제트펌프를 가동하고, 제트펌프에서 흡입력을 증가시킴으로써, 별도의 급수펌프나 펌프 구동동력 및 물 탱크 등의 부품들이 필요없게 되며, 이에 의해 일반 양수기 수준(또는 그 이상)의 흡입력을 갖게 할 수 있어 장치의 설치에 따른 비용이 적게 들고, 설치 및 이동이 간단한 효과를 발휘한다.As described above, the suction power enhancer of the high pressure water pump according to the present invention operates the jet pump using a part of the high pressure water generated in the self pump to deep water that cannot be sucked by its own suction power, and the jet pump Increasing the suction power in the system eliminates the need for separate water pumps, pump drive power and water tanks, thereby providing suction power at the normal water level (or higher), resulting in lower installation costs. Lift, install and move have a simple effect.

또한, 본 발명의 고압수 펌프의 흡입력 증강장치는 고압펌프의 흡입력을 증가시킴으로써, 유입 유량 부족에 따른 펌프의 손상을 막아주는 효과를 발휘한다.In addition, the suction power enhancer of the high pressure water pump of the present invention increases the suction power of the high pressure pump, thereby exerting an effect of preventing damage to the pump due to insufficient inflow flow rate.
