Abstract
The utility model provides a kind of steam turbine jacking oil system, including an oil supply loop and the oil feed line for being connected to main fuel tank and oil-feed port, it has been sequentially connected in series on oil feed line between the main fuel tank and oil-feed port and has been formed in parallel duplex strainer, high-pressure oil pump, leaf filter by two stainless steel filters, the duplex strainer precondition pressure table, the filter core of the duplex strainer is Pall filter cores, and filtering accuracy is 25 μm.The use of the utility model duplex strainer; increase flow area, rejection, hold dirty rate; enhancing and the protection board-like fuel filter element reliability of final stage; improve operation filter security, reliability; reduce and safeguard, reduce Master Cost; steam turbine jacking oil system failure and hidden danger are thoroughly eliminated, reduces maintenance repair and maintenance workload, enables long-term, stable, economy, safety the operation of jacking oil system.
Description
Technical field
It the utility model is related to a kind of steam turbine jacking oil system.
Background technology
Steam turbine jacking oil system be in the startup of unit, stopping process jiggering warming-up and during uniform decrease in temperature from jack up and turn
The effect of son, the elliptic bearing of Turbo-generator Set are equipped with high pressure jacking oil capsule, and the high pressure oil that shaft-raising gear is provided is turning
Static pressure oil film is formed between son and bearing oil sac, rotor is jacked up by force, avoids axle journal and axis during the steam turbine slow-speed of revolution
Dry friction between watt.
Jacking oil system of the prior art is mainly filtered by motor, high-pressure oil pump, automatic backwashing filter, the bitubular
The portions such as device, leaf filter, pressure switch, overflow valve, one-way throttle valve cover and stainless steel tube, annex composition, for effectively
Prevent the generation of pump emptying phenomenon, protect system, system inlets supply oil supply (the positive pressure oil of ＜ 0.4MPa using low-pressure）.Low pressure
Oil enters pumping hydraulic fluid port by backwash oil filter and bitubular oil filter, pumps the high pressure oil got and filters entrance through leaf filter
Each distributor reaches corresponding apical axis oil port, realizes the purpose for jacking up rotor.It is effectively guaranteed using two-stage oil strainer
System clean degree, but the system failure takes place frequently, and the reverse flushing filter screen of automatic backwashing filter uses metal screen, and strainer makes for a long time
With or unit open, under shut-down condition big flow run, easily cause metal screen blocking, reduce filter's flow, urgent defect occurs
Shi Zaocheng units jacking oil system can not come into operation, and influence unit and open, stop causing great unit failure, the resistance of double-drum filter
The potential generation of failure is filled in, the board-like fuel filter element of final stage is will also result in and blocks, cause to cause jacking(oil) pump to trip, Turbine Barring Gears
Tripping, jeopardizes jacking(oil) pump safe operation.
The content of the invention
In order to solve the above-mentioned technical problem the utility model provides a kind of steam turbine jacking oil system, thoroughly eliminates steam turbine
Jacking oil system failure and hidden danger.
The technical solution of the utility model is：A kind of steam turbine jacking oil system, including an oil supply loop and it is connected to master
The oil feed line of fuel tank and oil-feed port, has been sequentially connected in series duplex mistake on the oil feed line between the main fuel tank and oil-feed port
Filter, high-pressure oil pump, leaf filter.
Scheme further, the duplex strainer precondition pressure table.
Further, the duplex strainer is formed in parallel scheme by two stainless steel filters, and filter core is Pall filter cores.
Further, the filter element filtering precision is 25 μm to scheme.
Further, the high-pressure oil pump number is two to scheme and is connected in parallel, a preparation and a use.
The beneficial effects of the utility model are：The use of duplex strainer, increase flow area, rejection, hold dirty rate, increases
The strong and protection board-like oil filter of final stage（Jacking(oil) pump exports strainer）Filter core reliability, improves operation filter security, reliable
Property, reduce and safeguard, reduce Master Cost, thoroughly eliminate steam turbine jacking oil system failure and hidden danger, reduce maintenance repair and
Maintenance workload, enables the operation that jacking oil system is long-term, stable, economic, safe.

Fig. 1 is the utility model structure diagram.
Wherein：1st, main fuel tank, 2, pressure gauge, 3, duplex strainer, 4, filter core, 5, high-pressure oil pump, 6, leaf filter.
Embodiment
Clearly complete description is done to the utility model below in conjunction with the accompanying drawings, so that those skilled in the art is being not required
Under conditions of making creative work, it can fully implement the utility model.
Embodiment：As shown in Figure 1, a kind of steam turbine jacking oil system, including an oil supply loop and it is connected to master
The oil feed line 2 of fuel tank 1 and oil-feed port, has been sequentially connected in series pressure on the oil feed line 2 between the main fuel tank 1 and oil-feed port
Power table 7, duplex strainer 3, two and high-pressure oil pump 5, the leaf filter 6 being connected in parallel, the duplex strainer 3 is by two
Stainless steel filter is formed in parallel, and filter core 4 is Pall filter cores, and filtering accuracy is 25 μm.
The preferred embodiment to the utility model is described above, it should be pointed out that the utility model not office
It is limited to above-mentioned particular implementation, wherein the equipment and structure be not described in detail to the greatest extent are construed as using the common side in this area
Formula is practiced；Any those skilled in the art, in the case where not departing from technical solutions of the utility model ambit, foundation
The technical essence of the utility model still falls within this to any simple modifications, equivalents, and modifications made for any of the above embodiments
In the range of the protection of utility model technical solution.
