Description
Technical field
The invention belongs to gas turbine design fields, more particularly to low-pressure compressor blade industry, and in particular to a kind of low
Press compressor blade cleaning device.
Background technology
Gas turbine needs longtime running in outfield, and low-pressure compressor blade can pollute after longtime running in surface attachment
Object causes Change of leaf form, causes hydraulic performance decline, and the oil consumption of combustion engine complete machine increases, and user cost is caused to increase, and profitability declines.
Blade is located inside gas generator, can only also be visited during combustion engine maintenance shut-downs and inspected by hole, if inspecting discovery blade surface
It is seriously polluted, then it needs to handle blade, most thorough means are that gas generator is returned repair shop, by low pressure components point
Solution carries out the reparation of blade to part, in professional blade processing section, required afterwards again after dispatching from the factory after assembling and shop test
Time is longer.The downtime of gas turbine is longer, it is meant that outer field loss is bigger, therefore there is an urgent need to one kind to exist from operation
Under conditions of Bu Fan factories decompose, outfield, that is, enforceable combustion engine original position leaf cleaning technology and device.
The content of the invention
It is an object of the invention to provide a kind of low-pressure compressor blade cleaning equipments, overcome or alleviated by the prior art extremely
A few drawbacks described above.
The purpose of the present invention is achieved through the following technical solutions：A kind of low-pressure compressor blade cleaning equipment, including nozzle,
Conduit, woven hose and air intake duct, wherein air intake duct are assemblied at compressor inlet, which is in bell mouth shape, and at it
Circumferentially run through on wall surface and open up multiple nozzles；It is annular in shape that woven hose is used for suck purge liquid, the woven hose from external container
It is connected on the outside of around air intake duct casing, between the nozzle on the woven hose and air intake duct and conduit is set to support woven hose
And transmission cleaning solution, each nozzle wherein on air intake duct correspond to the conduit that is connected.
Preferably, the nozzle spray chamber inner wall is provided with the gasket for opening up multiple pin holes, and cleaning solution is passed through the spray
Mouth is in vaporific ejection.
Preferably, the nozzle and the coupled conduit are circumferentially uniformly arranged 6~8.
Preferably, the woven hose is connected circlewise by rubber tube by connector.
Preferably, the conduit is the hollow tube of metal material.
A kind of advantageous effect of low-pressure compressor blade cleaning equipment provided by the present invention is：Ring residing for gas turbine
Border is usually relatively more severe, and inner vanes easily pollute, and general who has surrendered brings loss difficult to the appraisal under gas turbine performance, by this hair
Bright cleaning device can not decompose gas turbine situ cleaning, promote gas turbine performance to original state.
Description of the drawings
Fig. 1 is the structure diagram of low-pressure compressor blade cleaning equipment of the present invention.
Reference numeral：
1- jet pipes, 2- conduits, 3- woven hoses, 4- air intake ducts.
Specific embodiment
To make the purpose, technical scheme and advantage that the present invention is implemented clearer, below in conjunction in the embodiment of the present invention
Attached drawing, the technical solution in the embodiment of the present invention is further described in more detail.In the accompanying drawings, identical from beginning to end or class
As label represent same or similar element or there is same or like element.Described embodiment is the present invention
Part of the embodiment, instead of all the embodiments.The embodiments described below with reference to the accompanying drawings are exemplary, it is intended to use
It is of the invention in explaining, and be not considered as limiting the invention.Based on the embodiments of the present invention, ordinary skill people
Member's all other embodiments obtained without creative efforts, belong to the scope of protection of the invention.
The low-pressure compressor blade cleaning equipment of the present invention is described in further details below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of low-pressure compressor blade cleaning equipment, including nozzle 1, conduit 2, woven hose 3 and air inlet
Road 4.Air intake duct 4 is assemblied at compressor inlet, and cleaning solution is by woven hose 3 and conduit 2, and by nozzle 1 in vaporific ejection, band turns
Compressor rotor sucking cleaning solution cleaned.Specially：Air intake duct 4 is in bell mouth shape, and is circumferentially passed through on its wall surface
It wears and opens up multiple nozzles 1, which is provided with gasket, and multiple pin holes are offered on the gasket so that cleaning solution to be led to
The nozzle 1 is crossed in vaporific ejection, in order to ensure that cleaning solution forms the uniformity of spray field, it is uniformly arranged 6 so as to which nozzle 1 is circumferential~
8, wherein the gasket pin hole rate on the spray chamber diameter and spray chamber of nozzle 1, can be manufactured into difference by each nozzle 1 as needed
The identical pattern of the pattern of specification or part, to meet the compression pump output bars in the case of different cleaning formulations, different outfields
Part.Cleaning solution is stored in external container by certain formulation ratio, and container is connected with woven hose 3 when cleaning set-up procedure,
The woven hose 3 is connected circlewise by rubber tube by connector, around 4 casing of air intake duct outside, to be taken out from external container
Cleaning solution is inhaled, connection sets conduit 2 between the nozzle 1 on the woven hose 3 and air intake duct 4, wherein the correspondence of each nozzle 1 is connected
A piece conduit 2, the conduit 2 are both the passage that woven hose 3 flows to spout, can be also used as infusion using the hollow tube of metal material
The support of pipe 3.
After cleaning procedure starts, the cleaning solution through supercharging is vaporific by being formed after woven hose 3, conduit 2, nozzle 1, presses simultaneously
Mechanism of qi operates, and cleaning solution is sucked, is attached on blade.By adjusting 1 specification of cleaning solution liquid supply pressure and nozzle, spray is adjusted
Spray amount is suitble to the cleaning of compressor under different conditions.The clean-up performance of number blade is different when different, and the time of cleaning will not yet
Together, final cleaning solution is discharged by the mudhole of compressor casing bottom.
The above description is merely a specific embodiment, but protection scope of the present invention is not limited thereto, any
