Abstract
The utility model proposes one kind to be applied to hydrogenerator high pressure oil system, it is characterized by comprising oil inlet, inlet port filter, oil pump, overflow valve, oil spilling mouth, filter and oil feed lines, the oil pump includes exchange oil pump and direct current oil pump, the filter is double-drum filter, and the oil feed line is successively arranged flow switch and ball valve.The utility model, it can be achieved that when generator inertia rotates when powering off suddenly, prevents thrust bearing hard grind from wiping and damaging generator by using ac pump and the straightway pump design of the using and the reserved；By using the design of flow switch, it can be achieved that the too low alarm function of flow in pipeline；It is designed by using the filter of the using and the reserved, when a job, another rest guarantees that high pressure oil system can continue working, it can be achieved that the purpose that can be safeguarded and be replaced simultaneously, guarantee working efficiency.
Description
[technical field]
The utility model relates to a kind of high pressure oil systems, in particular to one kind to be applied to hydrogenerator high pressure oil system.
[background technique]
To turbine-generator units, since thrust-bearing load is larger, (typically occur in unit to open when generating unit speed is lower
In dynamic and stopping process), oil film is partially thin between thrust bearing shoe valve and runner plate, rubs larger, is easy to appear the dangerous situation of dry friction, and add
The fast consume degree of thrust bearing shoe valve, finally shortens the service life of the thrust bearing, increases the expenditure of entreprise cost.Therefore,
It is necessary to during startup-shutdown, using high-pressure oil pump to injecting high pressure oil between thrust bearing shoe valve and runner plate to form oil film, with
Prevent non-lubricated rotation between tiling and runner plate from causing to wear.
[utility model content]
Based on this, it is necessary to provide a kind of applied to hydrogenerator high pressure oil system.
The purpose of this utility model is to provide one kind be applied to hydrogenerator high pressure oil system, the high pressure oil system,
Easy to operate, security performance is high, and job stability and duration are good.
In order to achieve the above object, the utility model provides following technical solution: it is high that one kind being applied to hydrogenerator
Compressed-oil system, it is characterised in that: including oil inlet, inlet port filter, oil pump, overflow valve, oil spilling mouth, filter and fuel feed pump
Road, the oil pump include exchange oil pump and direct current oil pump, and the filter is double-drum filter, and the oil feed line is successively arranged
Flow switch and ball valve.
Preferably, the exchange oil pump and direct current oil pump are the using and the reserved.
Preferably, the double-drum filter is the using and the reserved.
The utility model has the beneficial effects that by using ac pump and the straightway pump design of the using and the reserved, it can be achieved that suddenly
When generator inertia rotates when power-off, prevent thrust bearing hard grind from wiping and damaging generator；By using the design of flow switch,
The too low alarm function of flow in pipeline can be achieved；It is designed by using the filter of the using and the reserved, when a job, Ling Yitai
Rest guarantees that high pressure oil system can continue working, it can be achieved that the purpose that can be safeguarded and be replaced simultaneously, guarantees work effect
Rate.
[Detailed description of the invention]
Fig. 1 is the structural schematic diagram of the utility model；
Marginal data: oil inlet 1, oil absorption filter 2, oil pump 3, exchange oil pump 31, direct current oil pump 32, overflow valve 4, oil spilling
Mouth 5, filter 6, oil feed line 7, flow switch 71, ball valve 72.
Specific embodiment
A kind of top petrol tank applied to turbine-generator units described in the utility model is done into one with reference to the accompanying drawing
The explanation of step.
Embodiment: in conjunction with Fig. 1, one kind being applied to hydrogenerator high pressure oil system, it is characterised in that: including oil inlet 1,
Oil absorption filter 2, oil pump 3, overflow valve 4, oil spilling mouth 5, filter 6 and oil feed line 7, the oil pump 3 include exchange oil pump 31
With direct current oil pump 32, the filter 6 is double-drum filter, and the oil feed line 7 is successively arranged flow switch 71 and ball valve 72；
The exchange oil pump 31 and direct current oil pump 32 are the using and the reserved；The double-drum filter is the using and the reserved.
During the work time, the oil first in thrust bearing segment oil groove flow to oil suction by oil inlet 1 to the utility model
2 entrance of filter, the outlet of oil absorption filter 2 are connected to 3 entrance of oil pump, and the exit end of oil pump 3 is connected to filter 6, another termination
To overflow valve 4, the high pressure oil overflowed flow to oil spilling mouth by overflow valve 4 and comes back in thrust bearing segment oil groove, passes through
The high pressure oil of filter 6 is successively finally connected to bearing shell by oil-feed port after flow switch 71 and ball valve 72 in oil feed line 7
Oil filler point and realize that high pressure oil feeds the purpose in thrust bearing, and can quickly form effective oil film, shorten starting or stop
The time of machine.
Above-described embodiment is the explanation to the utility model, is not the restriction to the utility model, and any pair of sheet is practical new
Scheme after type simple transformation belongs to the protection scope of the utility model.
