본 발명은 웨스코형 펌프의 유로구조에 관한 것으로, 특히 임펠러 흡입구 및 임펠러 토출구를 임펠러에 대하여 접선 방향으로 형성하여 유로의 형상을 변경시킴으로써 유로 손실을 해소할 수 있게 한 웨스코형 펌프의 유로구조에 관한 것이다.The present invention relates to a flow path structure of a Wesco pump, and more particularly, to a flow path structure of a Wesco pump in which an impeller inlet port and an impeller discharge port are formed in a tangential direction with respect to the impeller so as to solve the flow loss by changing the shape of the flow path. will be.

일반적으로 웨스코형 펌프는, 기본적으로 연속적인 와류로 인한 와류 마찰 작용에 의하여 액체를 압송하는 기기로 알려지고 있는 바, 종래 기술에 의한 웨스코형 펌프의 일례를 첨부 도면에 의하여 설명하면 다음과 같다.In general, the wesco pump is known as a device for conveying liquid due to the vortex friction action due to continuous vortex, and an example of the wesco pump according to the prior art will be described with reference to the accompanying drawings.

제1도 내지 제3도는 웨스코형 펌프의 전형적인 실시 형태를 보인 것으로, 도면중 1은 베이스, 2는 모터, 3은 케이싱, 4는 임펠러, 5는 물탱크, 6은 체크 밸브, 7은 흡입구, 8은 토출구, 9는 임펠러 흡입구, 10은 임펠러 토출구를 보인 것이다.1 to 3 show a typical embodiment of a Wesco type pump, in which 1 is a base, 2 is a motor, 3 is a casing, 4 is an impeller, 5 is a water tank, 6 is a check valve, 7 is a suction port, 8 shows an outlet, 9 an impeller inlet, and 10 an impeller outlet.

상기와 같은 일반적인 웨스코형 펌프는, 모터(2)의 구동에 의하여 임펠러(4)가 회전하게 되면, 토출에 의한 진공이 발생되어 흡입구(7)로부터 유체가 흡입되며, 이와 같이 흡입구(7)로 흡입된 유체는 첵크 밸브(6)를 통과하게 되고, 임펠러 흡입구(9)를 통하여 케이싱(3)의 내부로 유입된다.In the general Wesco type pump as described above, when the impeller 4 is rotated by the driving of the motor 2, a vacuum is generated by discharge, and fluid is sucked from the inlet 7, and thus, to the inlet 7. The sucked fluid passes through the shank valve 6 and flows into the casing 3 through the impeller inlet 9.

이후, 임펠러(4)에 의하여 가압된 유체는 임펠러 토출구(10)를 통하여 물탱크(5)로 토출되고, 다시 토출구(8)를 통하여 외부로 토출된다.Thereafter, the fluid pressurized by the impeller 4 is discharged to the water tank 5 through the impeller discharge port 10, and is again discharged to the outside through the discharge port (8).

그러나, 상기와 같은 일반적인 웨스코형 펌프에 있어서는, 유체가 지나가는 유체의 유로가 대략 M의 형상을 갖는 구조로서, 유체가 임펠러 흡입구(9)로 유입될 경우, 임펠러 토출구(10)에서 토출될 경우에 급격한 유로의 변화가 일어나게 되므로, 유로 손실이 발생되는 단점이 있었으며, 따라서 웨스코형 펌프의 효율이 저하될 뿐만 아니라, 소음 발생이 원인이 되는 등의 여러 문제점이 있었다.However, in the above general Wesco pump, the flow path of the fluid passing through the fluid has a shape of M. When the fluid flows into the impeller inlet 9, when the fluid is discharged from the impeller discharge port 10. Since there is a sudden change in the flow path, there was a disadvantage that the flow path loss occurs, and thus there are various problems such as not only the efficiency of the Wesco pump but also the noise.

본 발명의 목적은 임펠러 흡입구와 임펠러 토출구에서의 급격한 유로 변화를 방지하여 유로 손실을 저감시킴으로써 효율을 향상시키고, 소음 발생을 저감시킬 수 있도록 한 웨스코형 펌프의 유로구조를 제공함에 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a flow path structure of a wesco pump that prevents abrupt flow path changes at an impeller inlet port and an impeller outlet port to reduce flow path loss, thereby improving efficiency and reducing noise.

상기와 같은 본 발명의 목적을 달성하기 위하여, 유체가 임펠러에 의하여 흡입구를 통해 흡입되어 임펠러 흡입구 및 임펠러 토출구를 돌아 토출구로 토출되는 웨스코형 펌프에 있어서, 상기 임펠러 흡입구와 임펠러 토출구를 그 흡입방향과 토출방향이 케이싱과 임펠러에 대하여 접선방향을 향하도록 형성하여 상기 흡입방향의 연장선과 토출방향의 연장선이 상기 케이싱 외부의 한점에서 교차되도록 구성한 것을 특징으로 하는 웨스코형 펌프의 유로구조가 제공된다.In order to achieve the object of the present invention as described above, in a Wesco pump in which fluid is sucked through an inlet by an impeller and is discharged through an impeller inlet and an impeller outlet, the impeller inlet and the impeller outlet are connected to the suction direction. The flow path structure of the wesco type pump is provided so that the discharge direction may be formed tangentially with respect to the casing and the impeller so that the extension line in the suction direction and the extension line in the discharge direction intersect at one point outside the casing.

이하, 본 발명에 의한 웨스코형 펌프의 유로구조를 첨부 도면에 도시한 실시례에 따라서 설명하면 다음과 같다.Hereinafter, the flow path structure of the wesco pump according to the present invention will be described according to the embodiment shown in the accompanying drawings.

제4도는 본 발명의 유로구조가 구비된 웨스코형 펌프의 주요부 구성을 보인 정단면도이고, 제5도는 제4도의 A-A선 단면도이다.4 is a sectional front view showing the configuration of the main part of the wesco pump equipped with a flow path structure of the present invention, and FIG. 5 is a sectional view taken along the line A-A of FIG.

이에 도시한 바와 같이, 본 발명에 의한 유로구조가 적용되는 웨스코형 펌프는, 유체가 케이싱(11)의 임펠러(12)에 의하여 흡입구(13)를 통해 흡입되어 체크 밸브(14)를 지나고 임펠러 흡입구(15) 및 임펠러 토출구(16)를 돌아 물탱크(17)로 유입된 후, 다시 토출구(18)로 토출되는 것이다.As shown in this, in the Wesco pump to which the flow path structure according to the present invention is applied, fluid is sucked through the inlet port 13 by the impeller 12 of the casing 11, passes through the check valve 14, and the impeller inlet port. 15 and the impeller discharge port 16 are returned to the water tank 17, and then discharged to the discharge port 18 again.

상기 임펠러 흡입구(15) 및 임펠러 토출구(16)를 케이싱(11)과 임펠러(12)에 대하여 접선 방향으로 형성하여 구성한 것이다.The impeller suction port 15 and the impeller discharge port 16 are formed in a tangential direction with respect to the casing 11 and the impeller 12.

즉, 제4도에 도시한 바와 같이 상기 임펠러 흡입구(15)의 흡입방향과 임펠러 토출구(16)의 토출방향은 케이싱(11)과 임펠러(12)에 대하여 접선 L1, L2 방향으로 형성되도록 함과 아울러 이들 접선 L1, L2의 연장선이 상기 케이싱(11) 외부의 한점에서 서로 교차하도록 구성되는 것이다.That is, as shown in FIG. 4, the suction direction of the impeller suction port 15 and the discharge direction of the impeller discharge port 16 are formed in the tangential L1 and L2 directions with respect to the casing 11 and the impeller 12. In addition, the extension lines of these tangents L1 and L2 intersect each other at one point outside the casing 11.

이와 같이 구성되는 본 발명의 유로구조가 구비된 웨스코형 펌프는 임펠러(12)가 회전하게 되면, 흡입구(13)를 통하여 유체가 흡입되며, 그 흡입구(13)를 통하여 흡입된 유체는 체크 밸브(14)를 통하여 임펠러 흡입구(15)로 유입되는 바, 이때 임펠러(12)의 접선 방향으로 유입된다.When the impeller 12 rotates, the wesco pump equipped with a flow path structure of the present invention configured as described above receives the fluid through the inlet 13, and the fluid sucked through the inlet 13 is a check valve ( 14 is introduced into the impeller inlet 15, in which case it is introduced in the tangential direction of the impeller 12.

이후, 임펠러(12)에 의하여 가압된 유체는 임펠러 토출구(16)를 통하여 물탱크(17)로 토출되는데, 이때에도 임펠러(12)의 접선 방향으로 토출되며, 다시 토출구(18)를 통하여 외부로 펌핑되는 것이다.Subsequently, the fluid pressurized by the impeller 12 is discharged to the water tank 17 through the impeller discharge port 16, and in this case, the fluid is discharged in the tangential direction of the impeller 12, and again to the outside through the discharge port 18. To be pumped.

이상에서 설명한 바와 같이 본 발명에 의한 웨스코형 펌프의 유로구조는 유체가 임펠러에 의하여 흡입구를 통해 흡입되어 임펠러 흡입구 및 임펠러 토출구를 돌아 토출구로 토출되는 웨스코형 펌프를 전제로하여 상기 임펠러 흡입구 및 임펠러 토출구를 그 흡입방향과 토출방향이 임펠러에 대하여 접선 방향을 향하도록 형성함으로써 유체를 임펠러 흡입구 및 임펠러 토출구에서 케이싱과 임펠러에 대하여 접선방향으로 흡입 및 토출하게 되므로 유체를 급격한 변화없이 유입 및 토출시킬 수 있게 되어 유체의 유로 손실을 감소시켜 웨스코형 펌프의 효율을 향상시키고 소음발생을 억제시키는 등의 효과가 있다.As described above, the flow path structure of the wesco pump according to the present invention is based on the assumption that the fluid is sucked through the suction port by the impeller and is discharged through the impeller suction port and the impeller discharge port to the discharge port. By forming the suction and discharge directions tangential to the impeller, the fluid is sucked and discharged in the tangential direction to the casing and the impeller at the impeller suction port and the impeller discharge port, so that the fluid can be introduced and discharged without sudden change. It is possible to reduce the flow path loss of the fluid to improve the efficiency of the Wesco type pump and to suppress the generation of noise.
