The utility model discloses can filter the mechanical particle in the empty side seal oil, improve the oil precision, stop because the emergence of the sealed tile wearing and tearing accident of generator that the oil reason causes.
Description
Technical Field
The utility model relates to a turbine generator set hydrogen seals oil system technical field, in particular to turbine generator air side seals oil system filter unit.
Background
The invention aims to solve the technical problem that a group of parallel filter screen devices (which can be used independently or in parallel and are convenient to switch) are additionally arranged at an outlet of an air side sealing oil pump of a sealing oil system of a steam turbine generator to filter mechanical particles in the air side sealing oil, improve the oil quality precision and avoid the occurrence of abrasion accidents of the sealing bush of the generator caused by the oil quality.
The phenomenon of contact abrasion between a sealing bush of a sealing oil system of a turbonator and a shaft neck is found to be very common in normal overhaul of a unit, and by repeated research, after overhaul and installation reasons (the clearance of the sealing bush is adjusted to be too small), the direct reasons are that the sealing bush is abraded due to poor oil quality (particles contained in oil), so that an air side sealing oil filter screen needs to be transformed, the oil filtering effect is improved, and the problem of abrasion of the sealing bush is effectively solved. The conventional air-side sealing oil scraper oil filter matched with a domestic thermal power generating unit can also play a role in filtering oil, but the filtering precision is poor, so that the requirement on the quality of the air-side sealing oil is difficult to meet, and the method is similar to the method.
Disclosure of Invention
An object of the utility model is to overcome the not enough of prior art, and provide a turbo generator set dead side sealing oil system filter unit that simple structure, oil strain effect are obvious.
In order to realize the purpose of the invention, the utility model adopts the following technical scheme: the utility model provides a turbo generator unit sky side sealed oil system filter unit, includes: the sealed oil pump of empty side comes female pipe of oil, the sealed oil pump of empty side export female pipe, parallelly connected filter unit, filter unit entry door, filter unit export door, the sealed oil export female pipe of empty side, its characterized in that: a parallel filter screen device is additionally arranged between an incoming oil main pipe of the air-side sealing oil pump and an outlet main pipe of the air-side sealing oil pump, and two filter screens of the parallel filter screen device are respectively connected in parallel between the incoming oil main pipe of the air-side sealing oil pump and the outlet main pipe of the air-side sealing oil pump; the upper side and the lower side of the filter screen are respectively provided with a filter screen device outlet door and a filter screen device inlet door; the two air side sealing oil pumps are respectively connected with the inlet doors of the two filter screen devices; the hollow side sealing oil outlet main pipe is connected with the sealing tile system; one side of the oil outlets of the two hollow side sealing oil pumps is communicated with a hollow side sealing oil pump outlet main pipe.
Through implementing above technical scheme the utility model discloses following technological effect has: impurities in the sealing oil on the air side are effectively filtered, the oil quality is improved, and the abrasion accident of the sealing bush of the generator is avoided.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
For better understanding of the technical solutions of the present invention, the following detailed description of the embodiments provided in the present invention is provided with reference to the accompanying drawings.
The utility model provides a steam turbine generator air side sealing oil system filter unit includes: the device comprises an empty side sealing oil pump incoming oil main pipe, an empty side sealing oil pump outlet main pipe, a parallel filter screen device, a filter screen device inlet door, a filter screen device outlet door and an empty side sealing oil outlet main pipe.
In the above embodiment, more specifically, as shown in fig. 1, without changing the direction of the original inlet and outlet pipelines of the empty-side sealing oil wiper oil filter group, high-precision parallel-connection filter screen devices 101 and 102 are installed at the position of the outlet main pipe 111 of the oil main pipe 109 of the empty-side sealing oil pump and the outlet main pipes 111 of the empty-side sealing oil pumps 107 and 108 by using the opportunity of overhaul of the unit, meanwhile, the inlet doors 103 and 105 and the outlet doors 104 and 106 of the filter screen devices are installed respectively at the front and the rear of the parallel-connection filter screen devices 101 and 102, and the installed oil pipe is connected with the empty-side sealing oil outlet main pipe 110 by flange movable and fixed connection (considering disassembly and assembly and disassembly for convenient maintenance) to. The connection size of each pipeline is reformed, the sealing is reliable by on-site surveying and mapping of engineering technicians, connection and the like, no leakage point exists, and the technical requirements of installing high-precision parallel filter screen devices are met.
The working principle of the filter screen device of the air side sealing oil system of the steam turbine generator is as follows: when a single-side filter screen device is required to work in the operation of a unit, an air-side sealing oil pump incoming oil main pipe 109 is subjected to pressure rise through an air-side sealing oil pump 107 and then sequentially enters an outlet main pipe 111, a single-side inlet door 103 of the filter screen device, a parallel filter screen device 101 and a single-side outlet door 104, and oil enters an air-side sealing oil outlet main pipe 110 to be connected and enters a sealing tile system; when the filter screen devices on two sides in parallel connection work, the inlet door 105 of the filter screen device on the other side is opened, and oil flows through the filter screen device 102 and the outlet door 106 and then enters the hollow side sealing oil outlet main pipe 110 to be connected and enter the sealing tile system; the single-side and double-side filter screen devices are convenient to switch and operate, and the maintenance and isolation are very convenient.
After the installation is finished, after the standby unit air side sealing oil pump is started to normally operate, the filter screen device, the connecting pipeline and the valve of the modified air side sealing oil system are dynamically observed to be free of leakage, the oil filtering effect is obvious, and the modification is shown to achieve the expected purpose.
It is right above the embodiment of the utility model provides a turbo generator set generator free side seals oil system filter unit has carried out detailed introduction, to the general technical personnel in this field, the foundation the utility model discloses the thought of embodiment all has the change part on concrete implementation mode and application scope, to sum up, this description content should not be understood as right the utility model discloses a restriction.
