Description
본 고안은 가압윤활유 밀봉부를 가진 펌프시일에 관한 것으로 가스, 공기압력, 진공 또는 고형유체물, 유체물등을 이송하는 펌프에 있어서 펌프의 샤프트와 축결합된 슬리브에 끼워 붙여져서 펌프샤프트와 함께 회전하는 회전링의면(RING FACE)에 맞닿은 밀봉부링의 면에 가압윤활유 유통로에 연통되는 가압윤활유 밀봉실을 형성하여 외부에 별도로 설치된 가압윤활기(LUBLICATOR)에 의한 가압윤활유를 가압윤활유 밀봉실에 공급하므로서 펌프에 가압윤활유 밀봉부를 형성시켜 헬리컬기어의 회전으로 펌프실내의 내용물이 밀봉부에 가해지는 가혹한 조건의 완화와 함께 밀봉부의 마찰면을 보호하여 밀봉부의 밀봉효과를 더욱 향상시킨 것이다.The present invention relates to a pump seal having a pressurized lubricating oil seal, and in a pump for transporting gas, air pressure, vacuum or solid fluid, fluid, etc., a rotation that is fitted to a sleeve axially coupled with a shaft of a pump and rotates with a pump shaft By forming a pressurized lubricating oil sealing chamber in communication with the pressurized lubricating oil flow passage on the face of the sealing ring which is in contact with the RING FACE, and supplying pressurized lubricating oil by a pressurized lubricator installed in the outside to the pressurized lubricating oil sealing chamber. The pressure lubricating oil seal is formed in the helical gear, and the frictional surface of the seal is protected by the rotation of the helical gear to reduce the harsh conditions applied to the seal.
종래에는 펌프의 밀봉부면이 스프링의 탄력에 의하여 밀봉되거나 펌핑액체에 의하여 밀봉되었으므로 펌핑액체의 난이도에 따라서 밀봉부면의 수명이 좌우되었으며, 밀봉부면에 공급되는 냉각윤활유는 외부에서 공급되어 누출되므로 폐수로 인한 주위환경 처리에 낭비를 유발시키는 문제점들이 있었다.Conventionally, since the sealing surface of the pump is sealed by the elasticity of the spring or sealed by the pumping liquid, the service life of the sealing surface depends on the difficulty of the pumping liquid, and the cooling lubricant supplied to the sealing surface is supplied from the outside and leaked into the wastewater. There was a problem causing waste in processing the surrounding environment.
본 고안은 이러한 문제점을 개선하여 펌핑액체에 관계없이 자체 윤활압력을 외부에서 조정하도록 구성하여 밀봉부면의 밀봉을 안정시키고 밀봉효과를 향상시킨다.The present invention improves this problem and is configured to adjust the self-lubrication pressure from the outside regardless of the pumping liquid to stabilize the sealing of the sealing surface and improve the sealing effect.
펌프의 밀봉부면에 가압윤활유 유통로와 연통되는 가압윤활유 밀봉실을 형성하여 밀봉부면 중앙에 윤활 및 냉각 압력을 외부에서 조정함으로써 자체 윤활냉각으로 안정적인 밀봉효과를 얻고, 헬리컬기어의 회전으로 펌프실내의 내용물에 가해지는 가혹한 조건의 완화와 함께 밀봉부의 마찰면을 보호하여 밀봉부의 밀봉효과를 향상시킨다.By forming a pressurized lubricating oil sealing chamber in communication with the pressurized lubricating oil flow passage on the sealing surface of the pump, the lubrication and cooling pressure is adjusted at the center of the sealing surface to obtain a stable sealing effect by self-lubricating cooling, and the rotation of the helical gear It protects the friction surface of the seal together with the alleviation of the harsh conditions applied to the contents to improve the sealing effect of the seal.

펌프샤프트(1)와 축결합 되었으며 선단에 헬리컬기어(2a)가 형성된 슬리브 (2)에 끼워 붙여져서 펌프샤프트(1)와 함께 회전하는 회전링(3)의 면(3a)에 맞닿은 밀봉부링(4)의 면(4a)에 플랜지(5a)에 뚫린 가압윤활유 유통로(5)와 가압윤활유 유통구멍(6a)으로 연통시킨 가압윤활유 밀봉실(6)을 형성하여 그 가압윤활유 밀봉실 (6)에 외부에 별도로 설치된 가압윤활기(7) 내의 가압윤활유가 공급되게 구성하였다.Sealing ring which is axially coupled with the pump shaft (1) and fitted to a sleeve (2) having a helical gear (2a) at its tip and abuts against the surface (3a) of the rotary ring (3) rotating together with the pump shaft (1). On the surface 4a of 4), the pressurized lubricating oil flow passage 5 opened through the flange 5a and the pressurized lubricating oil sealing chamber 6 communicated with the pressurized lubricating oil distribution hole 6a are formed, and the pressurized lubricating oil sealing chamber 6 is formed. It was configured to supply pressurized lubricating oil in the pressurized lubricator 7 separately installed outside.
그리고 밀봉부링(4)은 플랜지(5a)에 뚫린 가압윤활유 유통로(5)내에 끼워져서 내륜오링(6b)과 외륜오링(6c)에 의하여 밀봉되며 스프링(8)에 의하여 탄설되고 가압윤활유 밀봉실(6)에는 밀봉부링(4)에 뚫린 가압윤활유 유통구멍(6a)으로 가압윤활기(7)내의 가압윤활유가 가압윤활기(7)와 플랜지(5a) 사이에 연결된 가압윤활유 순환관(7a)을 통해 가압윤활유 유통로(5)에 가해져서 공급되고, 도면중 미설명부호 9는 펌프실이며, 10은 패킹이고, 11은 임펠러이다.The sealing ring 4 is inserted into the pressurized lubricating oil distribution path 5 drilled through the flange 5a and sealed by the inner ring o-ring 6b and the outer ring o-ring 6c, which is coalesced by the spring 8 and pressurized lubricating oil sealing chamber. 6, the pressurized lubricating oil in the pressurized lubricator 7 is a pressurized lubricating oil circulating pipe 7a connected between the pressurized lubricator 7 and the flange 5a by the pressurized lubricating oil distribution hole 6a of the sealing ring ring 4. It is supplied to the pressurized lubricating oil flow passage 5, and the reference numeral 9 in the figure is a pump chamber, 10 is a packing, and 11 is an impeller.
이와같은 본 고안은 가압윤활기(7) 내의 가압윤활유가 가압윤활유 순환관 (7a)과 가압윤활유 유통로(5)를 통해 순환되면서 가압윤활유 유통구멍(6a)과 연통된 가압윤활유 밀봉실(6)에 공급되어 회전링면(3a)과 밀봉부링면(4a)의 마찰면을 가압윤활유로 밀봉하므로 슬리브(2) 선단의 헬리컬기어(2a)의 회전이 펌프실 10내에 유출압력을 생기게하여 유체물이 밀봉부에 가해지는 조건을 완화시키는 것과 함께 밀봉부의 마찰면을 보호한다.The present invention is such that the pressurized lubricating oil in the pressurized lubricator (7) is circulated through the pressurized lubricating oil circulation pipe (7a) and the pressurized lubricating oil distribution passage (5), the pressurized lubricating oil sealing chamber (6) in communication with the pressurized lubricating oil distribution hole (6a) And the friction surface between the rotary ring surface 3a and the sealing ring surface 4a are sealed with pressurized lubricating oil, so that rotation of the helical gear 2a at the tip of the sleeve 2 creates an outflow pressure in the pump chamber 10 so that the fluid is sealed. It protects the friction surface of the seal as well as alleviating the conditions applied to it.
