Description

염수분무시험기용 노즐세척장치{Washing apparatus of nozzle for salt spray testing system}Washing apparatus of nozzle for salt spray testing system

본 발명은 염수분무시험기용 노즐세척장치에 관한 것으로서 더욱 상세하게는 염수시험을 위하여 염수를 분무하는 노즐에 염분이 고착되는 것을 방지할 수 있도록 한 노즐세척장치의 제공에 관한 것이다.The present invention relates to a nozzle washing apparatus for a salt spray tester, and more particularly, to the provision of a nozzle washing apparatus to prevent salts from adhering to a nozzle spraying saline for salt testing.

염수분무시험기는 외부에 도금을 행한 각종의 금속부품이나 금속제 외장케이스등의 부식정도를 시험하기 위하여 노즐을 통하여 지속적인 염수를 분무하는 장치를 말한다.The salt spray tester is a device that sprays continuous salt water through nozzles to test the degree of corrosion of various metal parts or metal outer cases that are plated on the outside.

이러한 염수분무시험기(10)의 구성은 도 1에 도시된 바와같이 염수공급수단(11)과 공기공급수단(12) 및 염수를 분무하기 위한 노즐(13)로 구성된다.The configuration of the salt spray tester 10 is composed of a salt water supply means 11, the air supply means 12 and the nozzle 13 for spraying the salt water, as shown in FIG.

상기 염수공급수단(11)과 공기공급수단(12) 및 노즐(13)상간에는 관체등으로 연결되는 공급라인(14)이 연결되고 염수공급수단(11)과 공기공급수단(12)에는 노즐(13)로의 염수와 공기를 공급하기 위한 펌프와 압축기와 같은 통상의 공급수단을 구비하게 된다.A supply line 14 connected to the brine supply means 11 and the air supply means 12 and the nozzle 13 is connected to a tube or the like, and the brine supply means 11 and the air supply means 12 have a nozzle ( 13) a common supply means such as a pump and a compressor for supplying brine and air to the furnace.

상기 염수공급수단(11)과 공기공급수단(12)으로부터 염수와 공기를 공급받는 노즐(13)은 중앙에 염수분사구(14)를 가지고 그 양측에는 공기분사구(15)를 가지도록 형성한다.The nozzle 13 receiving the brine and air from the brine supply means 11 and the air supply means 12 is formed to have a brine injection port 14 in the center and the air injection port 15 on both sides.

상기 노즐(13)의 팁(16)에는 염수분사구(14)와 공기분사구(15)가 일치하도록 구성한다.The tip 16 of the nozzle 13 is configured to coincide with the brine injection port 14 and the air injection port (15).

상기와 같은 염수분무시험기를 작동시키면, 염수공급수단과 공기공급수단을통하여 염수와 공기가 노즐로 공급되어 분사되는 과정에서는 공급되는 공기의 압력차에 의하여 양압이 발생하면서 분무가 이루어지게 된다.When operating the salt spray tester as described above, in the process of spraying the brine and air is supplied to the nozzle through the brine supply means and the air supply means is sprayed while generating a positive pressure by the pressure difference of the supplied air.

상기와 같은 분무현상은 분무실과 공급되는 공기 및 염수, 전원등 여러 조건의 변화와 초기설정에 따라 노즐의 팁부분에 염분이 고착되는 현상이 발생하게 된다.In the spray phenomenon as described above, the salt is fixed to the tip portion of the nozzle according to the change and initial setting of various conditions such as the air and the brine and the power supplied to the spray chamber.

상기와 같이 노즐팁에 염분이 고착될 경우에는 공급의 흐름에 변화를 주기 때문에 대기압이 소멸되지 않음으로서 양압이 발생되지 않기 때문에 분무현상이 중단되어 원활한 시험을 수행할 수 없게된다.When salt is fixed to the nozzle tip as described above, since the atmospheric pressure is not extinguished due to the change in the flow of the supply, since the positive pressure is not generated, the spray phenomenon is stopped and the smooth test cannot be performed.

특히, 노즐의 팁에 염분이 고착되더라도 이를 제거하기 위한 장치나 수단이 없는 관계로 염분고착시 일단 시험을 중단한 후 시험조건을 새로이 설정하거나, 노즐 팁에 고착된 염분을 제거한 후 다시 시험에 들어가야 하는 문제점이 발생한다.In particular, even if salt adheres to the tip of the nozzle, there is no device or means to remove it, so when fixing the salt, you must stop the test and set a new test condition, or remove the salt stuck to the nozzle tip and enter the test again. The problem arises.

상기와 같은 문제점들이 발생함으로서 시험시간의 지연으로 시험을 원활하게 할 수 없음은 물론, 시험신뢰도가 저하되는 등 많은 문제점들이 있었다.As the above problems occur, there are many problems such as not being able to perform the test smoothly due to the delay of the test time, and the test reliability is lowered.

이에 본 발명에서는 상기와 같은 문제점들을 해결하기 위하여 발명된 것으로서 공기공급라인의 중도에 순수(純水)를 공급하여 고착되는 염분을 제거할 수 있도록 함으로서 시험시간의 단축과 시험신뢰도의 향상등에 기여할 수 있도록 함을 목적으로 한다.Therefore, the present invention was invented to solve the above problems, by supplying pure water in the middle of the air supply line to remove the fixed salts, which can contribute to shortening the test time and improving test reliability. The purpose is to make it work.
