Description

터빈발전기의 윤활유 배관 세정시스템{Lubricant piping cleaning system for turbine generator}Lubricant piping cleaning system for turbine generator

본 발명은 터빈발전기 윤활유 계통에 설치된 배관내부 세정작업을 신속하고 안전하게 수행하기 위한 터빈발전기의 윤활유 배관 세정시스템에 관한 것이다.The present invention relates to a lubricating oil pipe cleaning system for a turbine generator for quickly and safely performing a cleaning operation inside a pipe installed in a turbine generator lubricating oil system.

터빈발전기의 윤활장치는 터빈 및 발전기 축이 회전할 때 베어링 및 기타 부위에 적당한 압력과 온도로 윤활유를 공급하여, 감마(減磨), 냉각, 밀봉(수소), 응력 분산, 방청, 청정 작용을 하는 장치이다. 터빈 및 발전기의 축은 고속 회전체이므로 적절한 윤활장치가 없으면 베어링과 축의 금속 마찰에 의하여 큰 손상을 초래한다. 따라서 충분한 보호장치가 필요하며, 터빈 정지시에도 축냉각을 위하여 윤활유를 계속 순환시킨다. The lubricating device of the turbine generator supplies lubricating oil at an appropriate pressure and temperature to the bearings and other parts when the turbine and generator shaft rotate, thereby reducing anti-friction, cooling, sealing (hydrogen), stress dissipation, rust prevention, and cleaning. is a device that Since the shaft of the turbine and generator is a high-speed rotating body, if there is no proper lubrication device, it causes great damage due to the metal friction between the bearing and the shaft. Therefore, a sufficient protection device is required, and the lubricating oil is continuously circulated for shaft cooling even when the turbine is stopped.

발전소 건설현장에서 터빈발전기 윤활유계통 세정작업은 기기의 안전한 운전을 위해 섬세하게 완료되어야 하는 공정으로 지금까지의 세정방법은 오래전부터 사용된 방법이나 소요기간이 길어 이 기간을 단축하기 위한 여러 가지 방안이 시행되었으나 성공 사례는 거의 없다. 특히 국내최초로 건설되는 1,000MW급 발전소의 경우 기기의 규모가 기존설비 대비 2배가량 증대되어 기존의 세정방법으로는 건설공정이 길어질 수밖에 없어 이에 대한 대책이 필요하다. At the power plant construction site, the cleaning of the turbine generator lubricating oil system is a process that must be delicately completed for the safe operation of equipment. It has been implemented, but there have been few success stories. In particular, in the case of a 1,000MW power plant to be built for the first time in Korea, the size of the equipment is doubled compared to the existing facilities, and the existing cleaning method will inevitably lengthen the construction process, so countermeasures are needed.

윤활유 배관의 세정은 터빈발전기 설치중 윤활유 및 밀봉유 계통 배관의 운송, 현장보관 및 설치 과정에서 잔류된 Mud, 용접scale, 쇳가루 등 불순물을 최초 운전 전에 완전히 제거하여 터빈 베어링 및 Sliding부의 손상과 마모를 방지하여 기기의 안전운전 및 수명연장을 위해 시행하는 중요한 과정이다. The cleaning of the lubricating oil pipe completely removes impurities such as mud, welding scale, and iron powder remaining during the transportation, on-site storage and installation of lubricating oil and sealing oil system piping during turbine generator installation before the first operation to prevent damage and wear of the turbine bearings and sliding parts. It is an important process implemented for safe operation and life extension of the device by preventing it.

기존의 터빈 윤활유배관 세정방법은 윤활유펌프 운전에 의한 정상적인 윤활유 흐름에 의해 배관내부를 세정하는 방식으로 진행되어 왔으며, 최근 윤활유세정 전 에어브로잉으로 배관내부 이물질을 사전제거 하는 방법으로 세정기간 단축을 시도하였으나 효과는 미미하며, 또 하나의 방법은 배관내부에 부착된 이물질을 신속히 제거하기 위해 윤활유배관을 외부에서 타격하는 방법(햄머링)으로 이 또한 효과는 제한되어 있다. The existing turbine lubricating oil pipe cleaning method has been carried out by cleaning the inside of the pipe by the normal flow of lubricating oil by the operation of the lubricating oil pump. I tried, but the effect is insignificant, and another method is a method of hitting the lubricant pipe from the outside (hammering) to quickly remove foreign substances attached to the inside of the pipe, and this also has a limited effect.
