모터(1)와 펌프몸체(2)를 서로마주보게 설치하여 모터축(1A)과 길다란 펌프축(2A)을 프랜지(101)(201)로 연결하여 펌프축(2A)은 베어링케이싱(3)의 베어링(4)으로 지지시키고 펌프몸체(2)의 내에 위치되는 펌프축(2A)에는 액체를 입구(2-1)로 흡입하여 출구(2-2)로 토출시키기위한 임펠러(5)를 고정하고 커버(6)(7)로 밀폐시키게된것에 있어서 모터(1) 일측에는 펌프몸체(2)측에서 이동되는 열을 차단하기위한 열차단판(8)을 설치하고 커버(6)에는 베어링(9)을 고정하여 펌프축(2A)의 끝부분을 지지시켜 진동과 소음발생을 감소시킬 수 있도록한 것을 특징으로한 것이다.The motor 1 and the pump body 2 are installed facing each other to connect the motor shaft 1A and the elongated pump shaft 2A with the flanges 101 and 201 so that the pump shaft 2A is the bearing casing 3. The impeller 5 for supporting liquid to the inlet 2-1 and discharging it to the outlet 2-2 in the pump shaft 2A, which is supported by the bearing 4 of the pump body 2 and is located in the pump body 2. In order to seal the cover (6) and (7), one side of the motor (1) is provided with a heat shield plate (8) for blocking the heat transferred from the pump body (2) side and the cover (6) bearing (9) ) To support the end of the pump shaft (2A) to reduce vibration and noise generation.

이와같이된 본 고안은 모터(1)를 작동시켜 모터축(1A)과 펌프축(2A)및 임펠러(5)를 회전시키는 것에 의하여 고온으로 가열된 액체를 입구(2-1)로 흡입하여 출구(2-2)로 토출하게되는 작동은 종래의 펌프와 동일하다.In this way, the present invention operates the motor 1 to rotate the motor shaft 1A, the pump shaft 2A, and the impeller 5 so as to suck the liquid heated to a high temperature into the inlet 2-1 and the outlet ( The operation to discharge to 2-2) is the same as the conventional pump.

상기에 있어서 본 고안은 펌프(1)의 일측에다 열차단판(8)을 설치하였으므로 펌프몸체(2)에서 발산되는 열기는 열차단판(8)에 의하여 모터(1)에 닿는 열기량은 대폭감소케되어 모터(1)는 높은온도로 가열되는 것이 방지된다. 이에따라 모터(1)의 손상을 방지하여 사용수명을 오래 유지시킬 수 있다. 그리고 열차단효율을 향상시키기 위해선 될수 있는한 열차단판(8)을 조금크게 형성하는것이 바람직하다. 또한 임펠러(5)가 고정되는 펌프축(2A)의 끝부위를 베어링(9)으로 지지하였으므로 임펠러(5)가 고속회전시에도 진동과 소음발생을 대폭감소시킬 수 있다.In the present invention, since the heat shield plate 8 is installed at one side of the pump 1, the heat emitted from the pump body 2 is greatly reduced in the amount of heat that reaches the motor 1 by the heat shield plate 8. Thus, the motor 1 is prevented from being heated to a high temperature. Accordingly, damage to the motor 1 can be prevented and the service life can be maintained for a long time. And in order to improve the heat shield efficiency, it is desirable to form the heat shield plate 8 as large as possible. In addition, since the end of the pump shaft 2A to which the impeller 5 is fixed is supported by the bearing 9, the impeller 5 can greatly reduce vibration and noise generation even at high speed.

이와같은 본 고안은 모터(1)의 일측에다 열차단판(8)을 설치하였으므로 펌프몸체(2)에서 발생되는 열기가 모터(1)에 닿아 모터(1)의 온도가 상승되는것을 방지할 수 있고 펌프축(2A)의 끝부위에 지지시킨 베어링(9)에 의하여 진동과 소음을 대폭감소시킬 수 있는 효과가 있다.Since the present invention is provided with a heat shield plate (8) on one side of the motor (1) it is possible to prevent the heat generated from the pump body (2) to reach the motor (1) to increase the temperature of the motor (1) The bearing 9 supported at the end of the pump shaft 2A has the effect of greatly reducing vibration and noise.
