본 고안은 부유물이 뒤섞인 유체 이송 및 오수등을 흡입, 토출함에 유용한 원판 펌프에 있어서, 특히 편심축에 축삽된 로우터 원판테의 운동작용이 정현 사인 파형으로 접동 됨으로써, 펑핑되는 원판 펌프의 회전축 베어링 메탈 부식 방지 구조에 관한 것이다.The present invention is a disk pump useful for suctioning and discharging squirt fluid and mixing of suspended solids. In particular, the movement of the rotor disk inserted into the eccentric shaft is sine wave, so that the rotating shaft bearing metal of the disk pump is popped. It relates to a corrosion protection structure.

제4도는 예를 들어 실용등록 제36256호로 공보에 기재된 종래의 원형 양수기의 내부 구조를 도시한 단면도이며, 도면에 있어서 (4)는 회전축이며 본체 내면에 끼워진 구형몸체(28)의 호면에 O 링(27)(27')과 부채꼴형 내압실(26)을 형성하고, 본체 내상측에 삽치홈(30)을 형성시키며 상기 회전축(4)에 축착된 편심축(25) 외주의 로우터 니들 베어링(19)(19')에 축설한 구형몸체(28)와 일체로 형성시킨 로우터원판(16)에 절개홈(31)을 형성시킨 다음, 상단에 패킹홈(32)이 형성된 접동봉(17)을 상길 절개홈(31)에 삽착시키고, 부채꼴형 격판(18)을 접동봉(17)의 패킹홈(32)에 끼우고 격판(18) 양측을 삽치홈(30) 각각에 끼워지도록 하고, 상기 로우터 원판(16) 외주연부에 패킹(29)을 끼워 설치하여서 된 원형 양수기의 구조를 구성하고 있다.4 is a cross-sectional view showing the internal structure of a conventional circular water pump described in, for example, Utility Registration No. 36256. In the drawing, (4) is an O-ring on the arc surface of the spherical body 28 fitted to the inner surface of the main body. (27) (27 ') and the fan-shaped pressure-resistant chamber 26, the insertion groove 30 is formed in the upper body of the main body and the rotor needle bearing of the circumference of the eccentric shaft 25 is fixed to the rotating shaft (4) 19) (19 ') is formed in the incision groove 31 formed in the rotor disc 16 formed integrally with the spherical body 28, and then the sliding rod (17) having a packing groove (32) formed on the top Inserted into the upper groove cutting groove 31, the fan-shaped diaphragm 18 is inserted into the packing groove 32 of the sliding rod 17 and both sides of the diaphragm 18 to be inserted into each of the insertion groove 30, the rotor The structure of the circular water pump formed by inserting the packing 29 in the outer peripheral edge of the disc 16 is comprised.

종래의 원형 양수기는 이상과 같이 구성되어 있으므로, 흡입구(2)로 부터 편심 원판 압축실(24)로 흡입된 산화물질 및 오수등이 구형몸체(28) 호면과 몸체 틈 사이로 유입되 로우터 니들 베어링(19)(19') 메탈부의 부식 산화를 유발시켜, 수명을 짧게 하는 결과를 낳았었다.Since the conventional circular pump is configured as described above, the oxide material and filthy water sucked from the suction port 2 into the eccentric disc compression chamber 24 are introduced between the surface of the spherical body 28 and the gap between the body and the rotor needle bearing ( 19) (19 ') Corrosion oxidation of the metal part was caused, resulting in a shortened lifetime.

따라서 상기 구형몸체(28)와 호면 틈 사이에 O링(27)(27')를 삽설하여 긴밀을 요하고 있지만 초당 수십번씩 접동되는 구형몸체(28)가 공극 틈 사이에서 강한 스트레스를 받아 O링(27)(27')이 쉽게 파열되는 현상은 상기 원형 양수기가 갖는 결정적 단점으로 실 사용면에 있어서 매우 불합리 하였던바, 또한 내압실(26)에 유입된 이물질등의 반복된 긴축 작용으로 펌핑 능력을 극도로 저하시킨 반면에, 회전축에 설치된 베어링부가 쉽게 부식되거나 누수로 인한 회전축의 마모를 유도하는 등의 제 결점이 있었다.Therefore, the O-rings 27 and 27 'are inserted between the spherical body 28 and the slit, but the spherical body 28, which slides dozens of times per second, is subjected to strong stress between the gaps. (27) (27 ') rupture is a decisive disadvantage of the circular pump has been very unreasonable in the actual use surface, and also the pumping capacity due to the repeated tightening action of foreign matter introduced into the pressure-resistant chamber (26) On the other hand, the bearing parts installed on the rotating shaft are easily corroded or induce wear of the rotating shaft due to leakage.

본 고안은 상기와 같은 문제점을 해소하기 위해 이루어진 것으로, 회전축 베어링 메탈의 부식을 방지하여 수명을 연장시킴과 동시에 편심원판 압축실(24)에서 발생되는 압력으로 말미암아, 구형몸체(28)와 호면 틈새로 누출된 유체를 다시 흡입구로 압출 시킴으로써 누수된 유체의 화학적 성분등으로 부터 베어링 메탈의 부식을 방지하고 편심축(25)의 마모등을 방지하여 내구성을 높이고, 내압으로 인한 펌핑 능력 저하를 방지토록 설치 구성한 원판 펌프를 얻는것을 목적으로 한다.The present invention has been made to solve the above problems, by preventing the corrosion of the rotating shaft bearing metal to extend the life and at the same time due to the pressure generated in the eccentric disk compression chamber 24, the spherical body 28 and the surface clearance By extruding the leaked fluid back into the suction port, it prevents corrosion of the bearing metal from the chemical composition of the leaked fluid, prevents wear of the eccentric shaft 25, and increases durability, and prevents a decrease in pumping ability due to internal pressure. It aims to obtain the disc pump installed.
