Abstract

PURPOSE: A pump without a rotation shaft is provided to achieve a function of a submersible pump by installing an impeller in a fluid reservoir and positioning a pump body at an outer portion of the fluid reservoir. CONSTITUTION: A pump includes an electromagnetic force generating unit(2) generating electromagnetic force. An impeller(1) is positioned in an area subject to the electromagnetic force of the electromagnetic force generating unit(2) in such a manner that the impeller(1) is operated by means of the electromagnetic force of the electromagnetic force generating unit(2). As the impeller(1) is operated, fluid is introduced into the pump through an intake hole formed in a case(5). Fluid introduced into the pump is exhausted out of the pump through an exhaust port(4) formed in the pump.

Description

회전축이 없는 펌프{Pump that unuse axis of rotation} Pump {Pump that unuse axis of rotation} no axis of rotation

유체를 이송하는 방법에 있어서 가장 보편화된 공법으로는 액체나 기체 등 유체를 퍼 올리거나 빨아올리는 장치로서 구조상 왕복펌프와 회전펌프로 크게 나눌 수 있다. As the most common method in the method for transferring a fluid may be divided as for increasing up buffer fluid such as liquid or gas, or sucked into the reciprocating pump and the rotary pump structure. 이중 왕복운동 펌프는 피스톤을 왕복시켜서 펌프 안의 기압을 낮춤으로써 생기는 대기압과의 차이를 이용하여 유체를 퍼 올리게 된 것이며 이 방 식의 펌프에는 흡펌프 , 밀펌프(피스톤 펌프),날개 펌프(윙 펌프)등이 있다. Dual reciprocating pump will the elevated by using the difference of the atmospheric pressure produced by lowering the pressure in by reciprocating the piston pump buffer fluid pump of this manner, the suction pump, a force pump (piston pump), the wing pump (Wing pump) and the like.

회전 펌프는 톱니바퀴나 날개바퀴를 전동기로 회전시켜 생기는 원심력으로 양수하게 되어있으며 왕복 펌프에 비하여 양수되는 양의 변동이 적고, 물뿐만 아니라 기름이나 도료, 아스팔트와 같은 끈적끈적한 것까지 다룰 수 있다. Rotary pump is the positive to the centrifugal force caused by rotating the gear or the impeller to the motor, and less amount of variation that is positive as compared to the reciprocating pump, it can be handled as well as the water to be sticky, such as oil or paint, asphalt. 대표적인 회전펌프는 원심 펌프(소용돌이 펌프), 기어 펌프 등이 있다. Typical rotary pumps include centrifugal pumps (vortex pumps), gear pumps.

본 발명은 회전축이 없는 펌프에 관한 것으로서 기존의 펌프들에 있어서 임펠러 등의 회전체의 회전을 유도하기 위해서는 필연적으로 구동체와 연결된 축이 필요하게 되며 회전체는 회전축을 통해 펌프 본체와 반드시 일체형으로서 설계되어야 했다. The invention will be required to lead to the rotor rotation of the impeller, such as in the conventional pump shaft inevitably associated with the actuator related to a pump without a rotational shaft rotating body is a necessarily integral with the pump body through the axis of rotation It had to be designed. 특히 수중펌프의 경우 펌프 전체가 직접 수중에 잠겨야만 제 성능을 발휘할 수 있으나 본 발명에 있어서 임펠러 등의 회전체의 회전을 유도하는 방식은 전자기력을 이용한 것으로서 회전체(임펠러)와 펌프의 본체는 일체형이 아니며 분리되도록 설계되어있다. In particular, the main body of system for guiding the rotating body the rotation of the impeller, etc. In the present invention, but the entire pump can directly exert the performance should immersed in water when the water pump is as using the electromagnetic force the rotating body (the impeller) and the pump are integrated this is not designed to be removed. 이를 통하여 유체가 저장된 저장조 내에 임펠러가 설치되고 펌프 본체는 저장조 외부에 위치됨으로서 수중펌프와 같은 효과를 얻을 수 있도록 설계되어있다. This impeller is installed in the reservoir of the fluid stored in the pump body through is designed to by being positioned outside the storage tank to obtain the same effect as the water pumps.

도면을 참조하여 본 발명을 상세히 설명하기로 한다. Reference to the drawings to describe the present invention in detail.

본 발명에 있어서 전자기력 발생장치(2)에 의해 발생된 전자기력의 영향권 내에 위치한 임펠러(1)는 전자기력에 의해 회전을 하도록 설계되어있다. The impeller (1) located within the sphere of influence of the electromagnetic force generated by the electromagnetic force generating device (2) according to the invention is designed to rotate by an electromagnetic force. 임펠러(1)의 회전에 의해 내부 Case(5)에 구성된 흡입구(3)를 통하여 유체가 흡입되어 내부 Case(6)에 설계된 토출구(4)를 통하여 외부로 이송될 수 있도록 설계되어있다. Through the discharge opening (4) is a fluid suction designed inside Case (6) through the inlet opening (3) constructed therein Case (5) by rotation of the impeller (1) is designed to be transferred to the outside.

상술한 바와 같이 본 발명의 주요 목적은 회전식 펌프에 있어서 임펠러 등의 회전체의 회전을 유도하는 방식에 있어서 전자기력을 이용하고자 하는 것이며 이를 통하여 기존의 펌프 등에서 반드시 필요로 하던 회전축을 사용하지 않아도 펌프로서 효과를 얻을 수 있는 것이 가장 큰 특징이다. The main object of the present invention as described above is a must pump without using the rotary shaft was required, etc. existing pumps intended to be used for the electromagnetic force in the way leading to the rotor rotation of the impeller such as by them in the rotary pump it is the biggest feature to get the effect. 이를 통하여 회전체와 펌프 본체의 분리가 가능해지며 펌프 본체가 이송하고자 하는 유체와 직접 닿지 않아도 되며 수중펌프의 경우 펌프 본체가 외부에 노출되어 있음으로 하여 그 유지 관리가 매우 쉽다. This need becomes possible through the time separation of the entire pump body and come in direct contact with the fluid by the pump unit to be transferred to the case that the pump body of the submersible pump is exposed to the outside of the maintenance is very easy. 또한 기존의 수중펌프 등이 유체와 직접적으로 접하여 있음과 동시에 펌프의 가동시 발생하는 열을 유체에 전달하도록 되어있는 것과는 달리 본 발명에 의한 축이 없는 펌프는 장치의 가동으로 인해 열발생이 이루어지는 주요 장치가 유체와 격리되어 있는 외부에 위치함으로서 펌프의 가동에 의한 열발생으로 인해 유체의 온도가 상승하는 것을 방지할 수 있다. Pump also without a shaft according to the present invention, unlike that is adapted to transfer heat generated during operation of the pump and at the same time that contact the such as conventional submersible pump with the fluid and direct the fluid key comprising a heat generated due to the operation of the device due to the heat generated by the device is movable by a pump located outside, which is isolated from the fluid it is possible to prevent the temperature of the fluid increases. 일반적인 수족관의 경우 수중펌프의 냉각을 위해 일정한 수족관용적을 유지하여야 하며 이는 수족관내 수온의 상승으로 인해 수생생물의 생장환경을 저해하지 않기 위함이며 따라서 수족관의 전체적인 크기를 필요이상으로 크게 하여야 하는 문제를 발생시킨다. In a typical aquarium should maintain regular aquarium volume for the cooling water pump, which in order not to inhibit the growth environment for aquatic life due to the rise of the temperature aquarium is therefore an issue that should increase the overall size of the aquarium than necessary to generate. 이러한 문제에 대하여 본 발명에 의한 축이 없는 펌프의 사용을 통해 수족관내 온도 상승 및 수생생물의 폐사를 우려하지 않아도 되며 따라서 수족관의 크기를 펌프의 용량과 상관없이 최소한으로 줄이는 것이 가능해 진다. This through the use of a pump without a shaft according to the present invention with respect to the problem aquarium and the temperature do not need to concern the mortality rises and the aquatic organisms thus making it possible to reduce the size of the aquarium to a minimum, regardless of the capacity of the pump.
