Abstract

The invention discloses a lubricating oil and jacking oil adjusting device for a power plant, and relates to the field of power plants, the lubricating oil and jacking oil adjusting device comprises a lubricating oil tank, a high-pressure cylinder, a medium-pressure cylinder, a low-pressure cylinder, a generator and a plurality of groups of bearings, the lubricating oil tank is connected with a jacking oil pump and a lubricating oil pump, and the jacking oil pump is connected with the lower parts of the plurality of groups of bearings through jacking oil pipelines, a lubricating pipeline of the lubricating oil pump is connected with the multiple sets of bearings, each of a first main pipe and a second main pipe is provided with a teletransmission pressure transmitter, the multiple sets of first branch pipes and second branch pipes are each provided with an electric adjusting door, the teletransmission pressure transmitters are wirelessly connected with a wireless repeater, and the wireless repeater is wirelessly connected with a server. The device can achieve the purpose of convenient and rapid wireless transmission, saves a lot of manpower and time due to the remote automatic adjustment, can be used for the progress grabbing of other equipment, and achieves the purpose of rapid completion on the premise that the time and manpower are not changed.

Description

technical field [0001] The invention relates to the technical field of power plants, in particular to a lubricating oil and jacking oil regulating device for power plants. Background technique [0002] As an important medium for safe operation, the oil system of a thermal power plant is responsible for lubricating the main shaft bearing of the unit and supporting the main shaft as a high-pressure medium during the start-up and shutdown of the unit. During the basic construction period of the unit and the subsequent maintenance period and operation period, it is necessary to adjust the jacking height of the main shaft of the unit and the lubricating oil pressure to meet the high-speed rotation of the rotor without friction. The oil circuit supplied by the lubricating oil tank of the unit to the bearing is divided into two paths: lubricating oil and jacking oil. During the normal operation of the unit, the lubricating oil enters the bearing through the lubricating oil pump, a...
