양흡입볼류트펌프 베어링 그리스 상태 감시기{Monitor for the State of Grease in Horizontal Double Suction Volute Pump Bearings}Monitor for the State of Grease in Horizontal Double Suction Volute Pump Bearings}

본 고안은 펌프 등의 윤활관리장치에 관한 것으로, 더욱 구체적으로는 상수도시설의 취수펌프 등을 관리함에 있어 최적 상태의 윤활관리를 하도록 하는 양흡입볼류트펌프 베어링 그리스 상태 감시기에 관한 것이다.The present invention relates to a lubrication management device such as a pump, and more particularly, to a suction system of a volute suction volute pump bearing grease to monitor lubrication in an optimal state in managing an intake pump of a water supply facility.

볼류트펌프는 원심펌프의 일종으로 안내날개가 없는 펌프이다. A volute pump is a type of centrifugal pump that does not have a guide vane.

이러한 원심펌프는 날개바퀴(impeller)를 빠른 속도로 회전시켜 액체에 회전운동을 주고 이 때 발생하는 원심력의 작용으로 액체를 수송하는 장치인데, 안내날개의 유무에 따라서 터빈펌프(turbine pump)와 볼류트펌프로 구분된다.The centrifugal pump is a device that rotates the wing wheel (impeller) at a high speed to give a rotational motion to the liquid and transports the liquid by the action of the centrifugal force generated at this time. It is classified as a lute pump.

볼류트펌프는 액체의 흐름을 조정하는 안내날개가 없는 대신 와류실(volute casing)이 날개바퀴에 바로 접해 있으므로 유체(流體)는 날개바퀴에서 와류실로 직접 송출되는 것으로서 비교적 낮은 압력에서도 많은 용량의 액체를 수송할 수 있으며, 구조가 간단해서 만들기 쉽다는 장점이 있다.Since the volute pump does not have a guide vane to control the flow of the liquid, the vortex casing is directly in contact with the vane wheel, so the fluid is discharged directly from the vane to the vortex chamber. It has the advantage of being able to transport it and its simple structure makes it easy to make.

또한, 날개바퀴가 1개로 유체를 한쪽에서만 흡입하는 펌프를 편흡입 볼류트펌프, 날개바퀴 2개가 붙어 있어 양쪽에서 흡입하는 펌프를 양흡입 볼류트펌프라고 하는데 양흡입 볼류트펌프의 경우 와류실에 유입된 액체를 특수한 흡입 통로를 통해 날개바퀴 양쪽으로 흡입하여 수송하므로 효율성이 높아 다량의 액체를 수송하는 데 적합하다In addition, a single suction wheel volute pump and a double suction wheel volute pump are attached to a pump that sucks fluid from only one side with one wing wheel. The double suction volute pump is called a double suction volute pump. Inflowed liquid is sucked and transported to both wing wheels through a special suction passage, so it is highly efficient and suitable for transporting large quantities of liquid.

이러한 양흡입볼류트펌프는 도 3에 도시된 바와같이 하부케이싱(10)과 상부케이싱(20)의 중앙부에 임펠라(30)와 상기 임펠라(30)를 지지회동시키는 축(40)이 양측의 베어링(50)에 의해 지지되어 있다.As shown in FIG. 3, the double suction volute pump has bearings on both sides of the shaft 40 for supporting the impeller 30 and the impeller 30 at the centers of the lower casing 10 and the upper casing 20. It is supported by 50.

상기 양측의 베어링(50)은 각각 베어링하우징(60)에 의해 보호되고 있으며, 상기 베어링하우징(60)의 내부에는 윤활작용을 위한 그리스가 주입되어 있다.Both bearings 50 are protected by bearing housings 60, and greases for lubrication are injected into the bearing housings 60, respectively.

즉, 양흡입볼류트펌프의 임펠라지지 및 부드러운 회전운동을 위한 베어링(50)은 대부분 그리스윤활을 하도록 하고 있다.That is, the bearing 50 for the impeller support and the smooth rotational movement of the double suction volute pump is to make the grease lubrication.

종래에는 펌프의 운전에 따른 그리스의 상태변화를 예측하기 위해서 온도센서를 이용하였으나 이러한 온도센서만으로는 그리스의 상태를 파악하기에는 다소 무리가 있어 관리가 제대로 이루어지지 못하는 문제점이 있었다.Conventionally, a temperature sensor was used to predict a change in grease according to the operation of a pump, but there was a problem that management was not performed properly because it was somewhat difficult to grasp the state of the grease using only the temperature sensor.

그런데 그리스는 온도변화, 수분침투 등 사용상태에 따라 점성이 변화하는 특성이 있으므로 이를 통하여 그리스의 상태를 판단할 수 있다. However, since grease has a characteristic of changing viscosity depending on the use condition such as temperature change and moisture penetration, it is possible to determine the state of grease.

본 고안은 이러한 그리스의 상태 변화의 특성을 이용하여 양흡입볼류트펌프의 베어링에 윤활작용을 하는 그리스의 상태를 보다 용이하게 시각적으로 감시 판단할 수 있도록 하므로서 펌프의 관리를 보다 용이하게 하도록 하는 양흡입볼류트펌프 베어링 그리스 상태 감시기를 제공하는데 그 목적이 있다.The present invention makes it easier to manage the pump by making it easier to visually monitor and determine the state of grease lubricating the bearings of the double suction volute pump using the characteristics of the state change of the grease. The purpose is to provide a suction volute pump bearing grease condition monitor.

본 고안은 하부케이싱과 상부케이싱의 중앙부에 설치된 임펠라와 상기 임펠라를 지지회동시키는 축과 상기 축의 양측을 지지하면서 부드럽게 회전하 하는 양측의 베어링 및 상기 베어링의 윤활작용을 위한 그리스가 주입된 베어링하우징을 포함하는 양흡입볼류트펌프에 있어서, 상기 베어링하우징에는 베어링의 회전운동에 대한 윤활작용으로 상태가 변화된 그리스의 상태를 파악하는 감시수단이 구비됨을 특징으로 한다.The present invention provides an impeller installed in the center of the lower casing and the upper casing, a shaft for supporting the impeller, bearings on both sides for smooth rotation while supporting both sides of the shaft, and a bearing housing injecting grease for lubricating the bearing. In the positive suction volute pump comprising, the bearing housing is characterized in that the monitoring means for identifying the state of the grease changed state by the lubrication action on the rotational movement of the bearing.

본 고안에 있어서 상기 감시수단은 상기 베어링하우징의 하단부에 천공된 관통공을 통하여 니플에 의해 연결된 볼밸브와; 상기 볼밸브에 의해 단속되며 상기 볼밸브를 통하여 흘러내리는 그리스를 모아 저장하도록 소켓에 의해 고정설치되는 저장용기를 포함한다.In the present invention, the monitoring means includes a ball valve connected by a nipple through a through hole drilled in the lower end of the bearing housing; And a storage container interposed by the ball valve and fixed by the socket to collect and store grease flowing down through the ball valve.

본 고안에 있어서 상기 저장용기는 내부를 관찰하도록 전체 또는 일부분이 투명재질임을 특징으로 한다.In the present invention, the storage container is characterized in that all or part of the transparent material to observe the inside.

이와 같은 본 고안은 윤활제인 그리스가 베어링하우징으로 부터 자중에 의해 흘러내리는 현상을 이용하기 때문에 설비에 수직으로 설치함으로써 양흡입볼류트펌프를 비롯한 횡축기계설비의 대부분에 적용이 가능하며, 간단한 원리와 구성으로서 제작 및 시공이 간단하여 그 소요비용이 매우 저렴하며, 그리스의 상태변화 감시를 통하여 설비의 사고예방을 위한 기본절차로 활용이 가능하도록 하는 것으로 기계설비의 관리를 위한 매우 유용한 효과를 갖는 기술이다.This invention uses the phenomenon that the grease, which is a lubricant, flows down from the bearing housing by its own weight, so it can be applied to most of the transverse mechanical equipment including the double suction volute pump by installing it vertically on the equipment. It is a technology that has very useful effect for the management of mechanical equipment by making it easy to manufacture and construct as a structure, so its cost is very low, and it can be used as a basic procedure for preventing accidents through monitoring of the change of grease. to be.

이하 본 고안의 실시예를 첨부된 도면에 의거하여 상세히 살펴본다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 고안 실시예의 구성을 보인 정면도이고, 도 2는 본 고안 실시예의 요부 구성을 보인 부분절개 확대도이다.1 is a front view showing the configuration of the embodiment of the present invention, Figure 2 is an enlarged partial cutaway showing the main configuration of the embodiment of the present invention.

본 고안의 실시예가 적용되는 양흡입볼류트펌프는 하부케이싱(10)과 상부케이싱(20)의 중앙부에 설치된 임펠라(30)와 상기 임펠라(30)를 지지회동시키는 축(40)과 상기 축(40)의 양측을 지지하면서 부드럽게 회전하도록 하는 양측의 베어링(50) 및 상기 베어링(50)의 윤활작용을 위한 그리스가 주입된 베어링하우징(60)을 포함하는 것으로 상기 베어링하우징(60)에는 베어링(50)의 회전운동에 대한 윤활작용으로 상태가 변화된 그리스의 상태를 파악하는 감시수단(100)이 구비되어 있다. The positive suction volute pump to which the embodiment of the present invention is applied includes an impeller 30 installed at the center of the lower casing 10 and the upper casing 20 and a shaft 40 for supporting the impeller 30 and the shaft ( 40 and bearing bearings 60 in which grease is injected for lubrication of the bearings 50 to support both sides of the bearings and rotate smoothly. Monitoring means (100) for grasping the state of the grease changed state by the lubrication action for the rotational movement of 50) is provided.

상기 베어링하우징(60)에 설치되어 그리스의 상태를 감시하는 상기 감시수 단(100)은 그리스의 흐름상태를 단속하는 볼밸브(110)와 흘러내린 그리스를 저장 관찰하도록 소켓(140)에 의해 고정설치되는 저장용기(120)를 포함한다.The monitoring unit 100 installed in the bearing housing 60 to monitor the state of the grease is fixed by the ball valve 110 to control the state of the grease and the socket 140 to store and observe the flowed grease. It includes a storage container 120 is installed.

상기 볼밸브(110)는 상기 베어링하우징(60)의 하단부에 천공된 관통공(61)을 통하여 니플(130)에 의해 연결되어 있으며, 상기 저장용기(120)는 상기 볼밸브(110)를 통하여 흘러내리는 그리스를 모아 저장하도록 하측에 설치되어 있다.The ball valve 110 is connected by a nipple 130 through a through hole 61 bored in the lower end of the bearing housing 60, the storage container 120 is through the ball valve 110 It is installed on the lower side to collect and store the flowing grease.

상기 저장용기(120)는 내부에 흘러내려 저장된 그리스의 상태를 관찰하도록 전체 또는 일부분이 투명재질의 창이 구비되어 있다.The storage container 120 is provided with a window of the transparent material in whole or in part to observe the state of the grease flowing down stored therein.

이와 같은 본 고안의 작용상태를 살펴본다.Look at the working state of the present invention as described above.

양흡입볼류트펌프의 양단부에 구비된 베어링하우징(60)의 내부에 주입되어 베어링의 원활한 회전을 가능하게 하는 윤활제인 그리스가 베어링의 윤활과정에서 변질되어 상태가 변하면서 상기 감시수단(100)으로 흘러내려 고여 저장된다.Grease, which is a lubricant injected into the bearing housing 60 provided at both ends of the double suction volute pump and enables smooth rotation of the bearing, is changed during the lubrication of the bearing, and the state is changed to the monitoring means 100. It is saved by flowing down.

즉, 처음 주입시에는 점성이 매우 큰 그리스의 성분에 수분 등이 침투됨과 아울러 기타 불순물이 혼합되고 베어링의 마찰에 의한 열의 발생으로 온도가 상승하면서 점성이 점정 떨어져 흘러내리게 되며, 자중에 의해 상기 베어링하우징(60)의 하측의 관통공(61)을 통하여 니플(130)에 의해 연결된 볼밸브(110)를 통하여 저장용기(120)로 흘러들어 모아지게 된다.That is, in the first injection, moisture and the like penetrate into the highly viscous grease, other impurities are mixed and the viscosity rises due to the heat generated by the friction of the bearing, and the viscosity flows away from the viscosity, and the bearing is caused by the weight of the bearing. It flows into the storage container 120 through the ball valve 110 connected by the nipple 130 through the through hole 61 of the lower side of the housing 60 to be collected.

상기 저장용기(120)는 투명재질로 구성되어 내부에 흘러든 그리스의 상태를 외부에서 관찰하여 상태를 판정할 수 있다.The storage container 120 is made of a transparent material to determine the state by observing the state of the grease flowing inside.

상기 저장용기(120)는 전체를 투명재질로 할 수도 있으나, 관찰이 용이한 어느 한부분만 투명재질로 구성되어도 무방하다.The storage container 120 may be made of a transparent material as a whole, but may be made of only a transparent material of any one part easy to observe.

이러한 감시수단(100)은 직접 현장에서 수시로 확인가능하므로 장치의 관리가 매우 용이한 단독장치로 설치할 수도 있고, 또한 다수의 장치나 원거리 무인관리의 경우 CCTV 등의 설비를 활용하여 보다 효율적인 관리가 가능하도록 하는 것이다.Since the monitoring means 100 can be checked from time to time directly on site, it can be installed as a standalone device that is very easy to manage the device, and in the case of a plurality of devices or remote unmanned management, it is possible to manage more efficiently by using facilities such as CCTV. To do that.

이와 같은 본 고안을 양흡입볼류트펌프에 적용하여 그리스의 변질상태를 실험한 바 점성의 저하로 흘러내린 그리스가 원래의 색깔과는 현저하게 다른 색으로 변질됨을 알 수 있었으며, 이러한 원인의 분석결과 패킹부 냉각을 위한 공급수가 회전자의 원심력에 의해 내측에서 외측으로 이동하는 현상으로 인하여 최종적으로 베어링 하우징으로 침투되면서 그리스의 상태변화를 촉진하는 것으로 판명되었다.As a result of applying the present invention to the positive suction volute pump, it was found that the grease deteriorated due to the deterioration of the viscosity changed to a different color from the original color. As the feed water for cooling the packing part moves from inside to outside due to the centrifugal force of the rotor, it finally proved to accelerate the change of grease state as it penetrated into the bearing housing.
