Description

모터의 로터를 겸한 스크류펌프{SCREW PUMP IN A MOTOR}SCREW PUMP IN A MOTOR}

본 고안은 모터의 로터를 겸한 스크류 펌프에 관한 것으로 보다 구체적으로 말하면 모터의 스테이터가 매립된 하우징 내부에 펌프실을 형성하고 영구자석이 몰딩된 로터에 회전펌프의 스크류를 형성하여 상기 펌프실에 회전펌핑되게 설치구성한 것을 특징으로 한 것이다.The present invention relates to a screw pump which also serves as a rotor of a motor. More specifically, the pump chamber is formed in a housing in which a stator of the motor is embedded, and a screw of a rotary pump is formed in a rotor in which a permanent magnet is molded so that the pump can be rotated in the pump chamber. It is characterized by the installation configuration.

일반적으로 각종 펌프는 별도의 구동수단인 모터나 엔진의 동력을 사용하여 구동하게 되어 있다. 예컨대 종래의 스크류 펌프는 별도의 구동수단인 모터의 동력이 동력전달 수단에 의하여 구동하게 되어 있다. 이때 펌프와 모터나 엔진 등을 별도로 각각 구비해야 함으로 운반 취급이 번거롭고 또 사용이 불편하며 사용공간이 넓어야 되고 동력의 전달수단에서 동력손실이 적지 않는 등의 문제점이 있었다.In general, various pumps are driven using the power of a motor or an engine which is a separate driving means. For example, in the conventional screw pump, the power of the motor, which is a separate driving means, is driven by the power transmission means. At this time, since the pump and the motor or the engine must be provided separately, the handling and handling is cumbersome and inconvenient to use, the use space should be wide and there is a problem that the power loss in the power transmission means is not small.

본 고안은 종래의 문제점을 시정하기 위하여 모터의 하우징 내부에 스테이터가 몰딩된 펌프실을 형성하고 영구자석이 몰딩된 로터에 스크류를 형성하여 로터를 겸한 스크류를 펌프실에 설치하고 모터에 교류전원을 공급하면 스테이터의 회전자계의 극성변화에 의하여 영구자석이 몰딩된 로터가 스크류와 함께 펌프실에서 회전되어 별도의 동력 전달수단을 구비하지 않고 모터의 동력으로 직접 스크류 펌프를 가동할 수 있게 된 것이다.The present invention is to form a pump chamber with a stator molded in the housing of the motor in order to correct the conventional problems, and to form a screw in the rotor with a permanent magnet molded to install a screw that serves as a rotor in the pump chamber and supply AC power to the motor Due to the polarity change of the stator's rotating magnetic field, the rotor with the permanent magnet molded therein is rotated in the pump room together with the screw so that the screw pump can be directly driven by the power of the motor without a separate power transmission means.

따라서 모터와 펌프가 일체형으로 되어 펌프기구가 간단하고 취급이 간편용이하며 별도의 동력 전달수단이 생략되며 소형모터 펌프의 구성이 가능하여 각종 용도로 보다 유용하게 사용할 수 있게 한 것이다.Therefore, the motor and the pump are integrated, so that the pump mechanism is simple, the handling is easy and the separate power transmission means is omitted, and the configuration of the small motor pump is possible to use more usefully for various purposes.

또한 펌프와 모터간에 동력의 전달수단이 없기 때문에 종래와 같은 동력 전달과정에서의 에너지 손실의 문제점이 해소되고 그만큼 동력의 이용률이 높게 되며 동력전달 수단의 기계적 소음이 없다.In addition, since there is no power transmission means between the pump and the motor, the problem of energy loss in the power transmission process as in the prior art is solved, the utilization rate of the power is high, and there is no mechanical noise of the power transmission means.

도 1 및 도 2에 표시된 바와 같이 모터(1)의 하우징(2)의 내부에 스테이터 (3)가 방수되게 몰딩된 펌프실(2b)을 형성하여 스테이터(3)의 회전자계의 자력이 펌프실(2b)의 로터(4)의 회전영역으로 투과되게 한다.As shown in FIGS. 1 and 2, a pump chamber 2b in which the stator 3 is molded to be waterproofed is formed inside the housing 2 of the motor 1 so that the magnetic force of the rotor magnetic field of the stator 3 is increased. Permeates into the rotational area of the rotor (4).

영구자석(4a)이 몰딩된 비자성체의 로터(4)의 외주면에 통상의 스크류(5)를 일체로 형성하고 모터의 좌우 측판(2b)에 통수공(2w)을 두고 형성된 축공(6a)에 링 (6b)과 함께 상기 로터(4)의 지축(6)을 끼워 상기 하우징(2)의 펌프실(2a)에 로터 (4)를 겸한 스크류(5)를 회전 펌핑되게 설치하여 구성된 것이다.In the shaft hole 6a formed with the conventional screw 5 integrally formed on the outer circumferential surface of the rotor 4 of the nonmagnetic material molded with the permanent magnet 4a, and having a water passage 2w in the left and right side plates 2b of the motor. The screw 6, which serves as the rotor 4, is rotatably installed in the pump chamber 2a of the housing 2 by fitting the support shaft 6 of the rotor 4 together with the ring 6b.

도면중 미설명부호 2n은 흡입구, 2u는 토출구이다.In the figure, reference numeral 2n denotes an inlet port, and 2u denotes an outlet port.

이와 같이 된 본 고안은 측판(2b)에 형성된 흡입관(2n)에 도시되지 않은 호스를 관접하여 펌핑할 유체에 담그고 모터(1)에 교류전원을 공급하면 스테이터(3)의 전자코어에 회전자계가 발생되면서 그 자력이 로터(4)의 영구자석(4a)에 작용하고 회전자계의 극성변화에 따라 로터(4)는 일방향으로 회전된다.According to the present invention as described above, when a hose not shown in the suction pipe 2n formed on the side plate 2b is immersed in a fluid to be pumped and AC power is supplied to the motor 1, the magnetic field is applied to the electronic core of the stator 3. As the magnetic force is generated, the magnetic force acts on the permanent magnet 4a of the rotor 4 and the rotor 4 rotates in one direction according to the polarity change of the rotor magnetic field.

로터(4)가 회전되면 로터(4)에 형성된 스크류(5)가 회전하면서 스크류에 의하여 펌프실(2b)에 구획되는 공간의 변위작용에 의하여 흡입관(2n)으로 유체를 흡인하여 펌프실(2a)을 거쳐 토출관(2u)으로 토출된다.When the rotor 4 is rotated, the screw 5 formed in the rotor 4 rotates and the fluid is sucked into the suction pipe 2n by the displacement action of the space partitioned in the pump chamber 2b by the screw to open the pump chamber 2a. Through the discharge tube 2u is discharged.

본 고안은 모터의 하우징 내부에 스테이터가 몰딩된 펌프실을 형성하고 영구자석으로 된 로터가 몰딩되게 스크류를 형성하여 펌프실에 설치하며, 모터의 로터를 겸한 스크류가 함께 회전하여 펌핑되게 구성하였기 때문에 모터와 펌프가 일체형으로 되어 펌프기구가 간단하고 고장이 거의 없으며, 초소형 펌프의 제작이 가능하여 펌프의 이용성을 높일 수 있다.The present invention forms a pump chamber in which a stator is molded in the housing of the motor, and a screw is formed in the pump chamber so that a rotor made of a permanent magnet is molded, and the screw, which serves as the rotor of the motor, rotates together and is pumped together. The pump is integrated, so the pump mechanism is simple and there is almost no breakdown, and it is possible to manufacture a compact pump, thereby improving the usability of the pump.

또한 모터와 스크류 펌프간에 별도의 동력 전달수단이 생략되기 때문에 동력전달 수단에 의한 동력 손실을 방지할 수 있어 그만큼 펌프의 동력 이용율이 보다 높게 된다.In addition, since a separate power transmission means is omitted between the motor and the screw pump, power loss by the power transmission means can be prevented, and thus the power utilization rate of the pump is higher.

또한 모터와 펌프가 한몸으로 되어 있어 모터 펌프의 설치공간이 그만큼 축소되고 좁은 공간에서도 사용이 가능하며 취급이 간편하여 종래의 스크류 펌프에 비하여 보다 편리하게 사용할 수 있는 등 여러 가지 효과가 있다.In addition, since the motor and the pump are in one body, the installation space of the motor pump is reduced by that amount, it is possible to use in a narrow space, and the handling is easy, and thus it can be used more conveniently than the conventional screw pump.
