Abstract
The utility model discloses a kind of steam turbine oil spout to test oil circuit, including：Oil spout experiment magnetic valve, connecting line, connection pump pressure switch, main oil pump delivery gauge, main oil pump outlet main pipe, described main oil pump export main pipe and sequentially connected by pipeline with main oil pump delivery gauge, connection pump pressure switch；It is in parallel connection that described oil spout experiment magnetic valve exports main pipe by connecting line and main oil pump；Described connecting line is diameter 15mm right-angle elbow pipe.The utility model again individually from main oil pump outlet main pipe take oil supply oil spout experiment magnetic valve, make unit do oil spout oil spout experiment during, prevent connection and open AC Lub oil pump, it is ensured that oil spout oil spout experiment be smoothed out.
Description
Technical field
Turbine emergency security system technical field is the utility model is related to, more particularly to a kind of steam turbine oil spout experiment oil
Road.
Background technology
The connected mode of the Dongfan Steam Turbine Factory 300MW fired power generating units oil spout experiment oil circuit of the country is at present：From main oil pump
Outlet main pipe draws oil pipe connection main oil pump pressure gauge, connection pump pressure switch, oil spout experiment magnetic valve successively；Its action process is
The powered action of magnetic valve is tested in oil spout, and pressure oil enters emergency governor, overspeed governor chamber, at a high speed rotation, into breaker chamber produce from
Mental and physical efforts, flying barrel being extruded, connection oil circuit oil pressure is tested in whole oil spout during this decreases, once oil pressure is down to connection pump
Pressure switch working value, then connection opens AC Lub oil pump.The power plant having at present does not join in order to ensure unit does oil spout experiment opens
Oil pump, do not change former design oil spout experiment oil circuit, throttle orifice is installed additional in oil spout experiment magnetic valve oil extraction sky, to limit oil drain quantity,
Ensure connection pump pressure switch motion value to greatest extent, avoid connection from opening grease pump, this is similar with the present invention.For improved
Oil circuit is tested in oil spout, is cancelled the connection oil circuit between connection pump pressure switch and oil spout experiment magnetic valve, is exported again in main oil pump
Connected pipes are installed additional with oil spout experiment magnetic valve, individually take main oil pump outlet main pipe for oil spout experiment magnetic valve power at main pipe
With oil, thoroughly avoid, because unit is done during oil spout experiment because magnetic valve pressure release is tested in oil spout, causing connection to open exchange lubrication
The phenomenon of oil pump.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art, and providing one kind can thoroughly avoid because unit is done
Because magnetic valve pressure release is tested in oil spout during oil spout experiment, connection is caused to open the steam turbine oil spout examination of the phenomenon of AC Lub oil pump
Test oil circuit.
The utility model adopts the following technical scheme that realization, a kind of steam turbine oil spout experiment for achieving the above object
Oil circuit includes：Oil spout experiment magnetic valve, connecting line, connection pump pressure switch, the outlet of main oil pump delivery gauge, main oil pump are female
Pipe, described main oil pump export main pipe and sequentially connected by pipeline with main oil pump delivery gauge, connection pump pressure switch；Described
It is in parallel connection that oil spout, which tests magnetic valve and exports main pipe by connecting line and main oil pump,；Described connecting line is diameter 15mm
Right-angle elbow pipe.
Again individually from main oil pump outlet, main pipe takes oil supply oil spout experiment magnetic valve to the utility model, unit is done oil spout
During oil spout experiment, prevent connection and open AC Lub oil pump, it is ensured that oil spout oil spout experiment is smoothed out.
Brief description of the drawings
Fig. 1 is structural frames line chart of the present utility model.
Embodiment
In order to be better understood from the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings and provides
Embodiment.
The utility model adopts the following technical scheme that realization, a kind of steam turbine oil spout experiment for achieving the above object
Oil circuit includes：Oil spout experiment magnetic valve 101, connecting line 106, connection pump pressure switch 102, main oil pump delivery gauge 104, master
Fuel pump outlet main pipe 105, described main oil pump export main pipe 105 by pipeline 103 sequentially with main oil pump delivery gauge 104,
Join the connection of pump pressure switch 102；Described oil spout experiment magnetic valve 101 exports main pipe 105 by connecting line 106 and main oil pump
In parallel connection；Described connecting line 106 is diameter 15mm right-angle elbow pipe.
After installing, to the comprehensive metal radiological survey X of pipeline weld seam and base transformed, run after system is oil-filled, inspection
Total system ne-leakage is looked into, no-load run after Steam Turbine starts, oil spout experiment is carried out by oil spout test logic, passes through experiment
Dynamic is observed, if experiment process is normally carried out and opens grease pump phenomenon without connection, illustrates transformed oil spout experiment oil piping system
Reach expected correctional effect, show to transform successfully.
A kind of steam turbine oil spout experiment oil piping system provided above the utility model embodiment is discussed in detail, for
Those of ordinary skill in the art, the thought of foundation the utility model embodiment, in specific embodiments and applications
It will change, in summary, this specification content should not be construed as to limitation of the present utility model.
