전동 양수기 { Electric motion water meter }Electric motion water meter

본 발명은 전동모터를 이용하여 낮은 곳의 물을 높은 곳으로 퍼올리는 전동 양수기에 관한 것으로 더욱 구체적으로는 양축형 전동모터를 사용하여 전동모터의 양측에 동일한 규격을 가지면서 임펠러의 회전방향이 반대가 되도록 하여 구성한 양수부를 접속함으로써 하나의 전동모터를 이용하여 두대의 양수기를 돌려 두배의 물을 퍼올릴 수 있게 한 전동 양수기이다.
The present invention relates to a motor-driven water pump for raising low-level water to a high place by using an electric motor, and more particularly, to a motor-driven water pump which uses a biaxial electric motor and has the same specifications on both sides of an electric motor, So that two water pumps can be turned by using one electric motor to pump water twice.

낮은 곳의 물을 높은 곳으로 퍼올리는 기계인 양수기는 일반적으로 흡수구와 토출구를 구비하고, 내부에 임펠러가 설치된 양수부와, 양수부 일측에 부착되어 구동축을 양수부 내부로 투입해 양수부의 임펠러를 회전시키는 전동모터로 구성된다.A water pump which is a machine for pumping low water to a high place is generally equipped with an absorption port and a discharge port and has a pumping part provided with an impeller inside and a pump attached to one side of the pumping part to feed the drive shaft into the pumping part, And an electric motor for rotating the motor.

그런데 위와 같이 전동모터를 이용하여 양수부의 임펠러를 회전시키는 종래의 일반적인 전동 양수기는 하나의 전동모터를 이용하여 하나의 양수부 내부에 설치된 임펠러를 회전시켜 낮은 곳을 물을 높은 곳으로 퍼올리기 때문에 전동모터의 힘에 따라 양수 용량이 정해지게 되므로 더욱 많은 양의 물을 빠른 시간에 퍼올리기 위해서는 다수의 양수기를 사용해야 하는데, 이처럼 다수의 양수기 사용을 위해서는 각각의 양수기에 설치된 전동모터에 전력을 공급해야 하는바 전력 소비가 증가하는 문제점이 있고 소음이 증가하는 문제가 있다.
Conventionally, a conventional electric power pump for rotating an impeller of a pumping part using an electric motor as described above uses an electric motor to rotate an impeller installed inside a pumping part to raise water to a high place, As the amount of water is determined according to the power of the motor, it is necessary to use a plurality of water pumps in order to increase the amount of water in a short time. In order to use such a water pump, electric motors installed in each water pump must be supplied There is a problem that the power consumption of the bar is increased and the noise is increased.

첨부도면 도 1 내지 도 4에서 도시한 바와 같이 본 발명은 전동모터(1)의 양측으로 회전축을 돌출 형성하여 동시에 회전되게 하되, 제1측단(101)이 돌출되는 전동모터(1)의 일측면에는 수냉각부를 형성하여 수냉각부 외측에 임펠러 회전방향이 정 방향으로 이루어지는 구성의 제1양수부(2)를 구성하고, 제2측단(102)이 돌출되는 전동모터(1)의 타측면에는 공냉각부를 형성하여 공냉각부 외측에 임펠러의 회전방향이 제1양수부의 임펠라 회전방향과 반대가 되게 한 제2양수부(2a)를 형성한 구성으로 이루어지는데 이를 보다 구체적으로 설명하면 다음과 같다.
As shown in FIGS. 1 to 4, the present invention can be applied to an electric motor 1 in which a rotary shaft is protruded from both sides of an electric motor 1 and rotated simultaneously, And the other side surface of the electric motor 1 in which the second side end 102 protrudes is formed with air cooling (air cooling) on the outer side of the water cooling corner, And a second positive number portion 2a is formed outside the air-cooling angle portion so that the direction of rotation of the impeller is opposite to that of the impeller of the first positive portion. This will be described in more detail as follows.

본 발명의 전동모터(1)는 양측으로 회전축을 돌출 형성한 양축형 모터를 사용함으로써 전동모터(1)의 회전 축력을 전동모터(1) 양측으로 동시에 출력하게 된다.The electric motor (1) of the present invention uses a biaxial-type motor in which a rotary shaft is protruded on both sides, thereby simultaneously outputting the rotational axial force of the electric motor (1) to both sides of the electric motor (1).

한편, 본 발명의 수냉각부는 제1측단(101)이 돌출 형성된 전동모터(1)의 일측면에 저수공간(303)을 형성한 물집커버(3)를 나사 결합하여 물집커버(3)의 중앙부를 관통하는 제1측단(101)과 물집커버(3)의 내벽 간에 베어링(301)과 누수방지부재(302)를 설치하고, 물집커버(3)의 저수공간(303)과 연통되도록 일측면에 통수공(206)을 형성한 몸체커버(205)가 설치된 양수부를 물집커버(3) 일측에 나사 결합하게 된다.The water cooling portion of the present invention is a water cooling portion which is formed by screwing a blister cover 3 having a water storage space 303 formed on one side of an electric motor 1 protruded from a first side end 101, A bearing 301 and a waterproofing member 302 are provided between the first side end 101 passing through the blister cover 3 and the inner wall of the blister cover 3, And the water-filled portion provided with the body cover 205 formed with the water supply hole 206 is screwed to one side of the blister cover 3.

따라서, 전동모터(1)의 제1측단(101)이 회전하면 제1측단(101)의 단부에 결합된 임펠러(204)가 제1양수부(2) 내부에서 정 방향 회전함으로써 제1양수부(2)의 흡수구(202)를 통해 양수실(201)로 물을 빨아올린 후 그 물을 토출구(203)를 통해 배출함으로써 낮은 곳의 물을 높은 곳으로 퍼올릴 수 있게 된다. When the first side end 101 of the electric motor 1 is rotated, the impeller 204 coupled to the end of the first side end 101 rotates in the first direction within the first water pumping portion 2, The water is sucked into the amniocentesis chamber 201 through the absorption port 202 of the main body 2 and the water is discharged through the discharge port 203,

이때, 흡수구(202)를 통해서 양수실(201)에 채워진 물은 제1양수부(2)의 몸체커버(205) 일측에 형성된 통수공(206)을 통해 물집커버(3)의 저수공간(303)으로 유입되어 저수공간(303)에 물이 채워짐으로써 물집커버(3)를 냉각시켜 물집커버(3)의 내측에서 베어링(301)에 의해 지지되는 제1측단(101)이 회전할 때 발생하는 마찰열을 냉각시켜 줌으로써 제1측단(101)의 과열을 방지할 수 있게 된다.
The water filled in the amphibious water chamber 201 through the absorption port 202 flows into the water storage space 303 of the blister cover 3 through the water hole 206 formed at one side of the body cover 205 of the first water purification unit 2 And is filled with water in the water storage space 303 to cool the blister cover 3 and to generate heat when the first side end 101 supported by the bearing 301 rotates inside the blister cover 3 It is possible to prevent the first side end 101 from overheating by cooling the frictional heat.

한편, 본 발명의 공냉각부는 제2측단(102)이 돌출 형성된 전동모터(1)의 일측면에 커버브라켓(4)을 나사 결합하고, 전동모터(1)의 제2측단(102)에는 커버브라켓(4) 내부에 위치하도록 냉각팬(401)을 나사 결합하여 커버브라켓(4)에 형성된 다수의 통공부(402)를 통해 커버브라켓(4) 내외부로 공기가 소통되게 하고, 커버브라켓(4) 외측면에는 제2양수부(2a)를 나사 결합한 구성이다.In the air cooling leg portion of the present invention, the cover bracket 4 is screwed to one side of the electric motor 1 in which the second side end 102 is protruded, and the cover 102 is attached to the second side end 102 of the electric motor 1 The cooling fan 401 is screwed so as to be positioned inside the bracket 4 so that air is communicated to the inside and the outside of the cover bracket 4 through the plurality of through holes 402 formed in the cover bracket 4 and the cover bracket 4 And the second amphibious portion 2a is screwed to the outer surface.

따라서, 전동모터(1)의 제2측단(102)이 회전하면 제2측단(102)의 단부에 결합된 임펠러(204)가 제2양수부(2a) 내부에서 제1양수부의 임펠러 회전방향과 반대로 회전하여 양수하게 되고, 제2측단(102)에 결합된 냉각팬(401)이 회전하면서 커버브라켓(4)의 통공부(402)를 통해 외부 공기를 빨아들여 커버브라켓(4) 내부에서 바람을 일으켜 전동모터(1)의 케이스를 냉각함으로써 전동모터(1) 내부의 과열을 방지하게 된다.Therefore, when the second side end 102 of the electric motor 1 is rotated, the impeller 204 coupled to the end of the second side end 102 moves in the impeller rotation direction of the first positive portion within the second positive water portion 2a, The cooling fan 401 coupled to the second side 102 rotates while sucking the outside air through the passage 402 of the cover bracket 4 and blowing air from inside the cover bracket 4 So as to cool the case of the electric motor 1, thereby preventing the electric motor 1 from overheating.

아울러, 수냉각부에 의해 냉각되는 전동모터(1)의 회전축 제1측단(101)과 공냉각부에 돌출 형성된 전동모터(1) 회전축의 제2측단(102)은 하나의 회전축이므로 수냉각부에 의한 전동모터(1)의 회전축의 냉각효과는 수냉각부에 위치하는 회전축 제1측단(101)과, 공냉각부에 위치하는 회전축 제2측단(102)에 동시에 작용함으로써 전동모터(1) 양측에 설치되는 양수부 작동이 원활히 이루어질 수 있게 되며 제1양수부의 임펠러와 제2양수부의 임펠러는 회전방향이 반대가 되도록 구성되어 회전축에 결합되어 있기 때문에 힘의 배분이 균형되어 원활하게 회전하므로 편마모현상이 없으면서 회전이 진행되어 소음을 줄일 수 있고 힘의 낭비도 막아 양수량이 두배가 되는 전동양수기를 얻게 되는 것이다.
Since the first side end 101 of the electric motor 1 cooled by the water cooling part and the second side 102 of the rotary shaft of the electric motor 1 protruded from the air cooling corner part are one rotation axis, The cooling effect of the rotating shaft of the motor 1 acts on both the first side end 101 of the rotating shaft located at the water cooling corner and the second side end 102 located at the air cooling corner, The impeller of the first hydraulic portion and the impeller of the second hydraulic portion are configured to be opposite to each other in the direction of rotation so that the power distribution is balanced and smoothly rotated. The noise can be reduced and the waste of power can be prevented to obtain the electric water pump having the double water amount.
