Oil supply system for jacking oil of auxiliary thrust bearing of main pump of nuclear power unit

The invention belongs to the technical field of nuclear power, and particularly relates to a jacking oil supply system for a main pump auxiliary thrust bearing of a nuclear power unit. According to the nuclear power unit main pump auxiliary thrust bearing jacking oil supply system, a main pump auxiliary tile jacking oil system device is additionally arranged, before the main pump is started or stopped, the main tile jacking oil pump and the auxiliary tile jacking oil pump are started through the jacking oil pump motor, a main pump rotor can be jacked up to the ideal height, and therefore the main pump rotor can be jacked up; lubricating oil can enter the space between the auxiliary tile and the thrust disc to form an oil film, so that the risk that the auxiliary tile and the thrust disc are seriously abraded is effectively avoided, and safe starting and running of the auxiliary tile are ensured. 本公开属于核电技术领域，具体涉及一种核电机组主泵副推力轴承顶轴油供油系统。本公开的核电机组主泵副推力轴承顶轴油供油系统，增加了主泵副瓦顶轴油系统装置，在启动或停运主泵前，通过顶轴油泵电机启动主瓦顶轴油泵和副瓦顶轴油泵，可以将主泵转
