The efficiency of mechanism of qi, so as to reduce the efficiency of unit.Therefore, it is necessary to configure compressor blade cleaning device and system to after dirty
Compressor blade is cleaned to recover the performance of compressor, and increase combustion engine is contributed.
The combustion engine air inlet that compressor blade purging system sprays into water before IGV, the cleaning of current combustion engine compressor blade
Device uses demineralized water, in shower nozzle entrance pressure of supply water typically in 0.3~0.5MPa or so, mainly meets at atomizer
Vaporific and good shape water spray is formed, sprays into certain water, ensures the cleaning performance of blade.In pump type selecting, pump
Rated pressure（0.98MPa）The generally greater than pressure of shower nozzle entrance.
In order to ensure the safe operation of pump and enough irrigation pressure and flow water be provided to combustion engine, set most in pump discharge
Low discharge loop recovery tank.When rinse water feed water valve is closed, the water of pump discharge in loop by setting minimum discharge orifice plate to return
The safe operation that water tank ensures pump is flowed to, now pump reaches maximum working pressure (MWP), energy consumption highest.But when rinse water feed water valve is opened
When, by the changes in flow rate of orifice plate, pump discharge pressure reduces, flow also relative change.Therefore cleaned in combustion engine compressor blade
During so that pump is run under frequent variable working condition, larger to pump loss, and consuming energy.
Utility model content
In order to solve the above-mentioned technical problem the purpose of this utility model is, there is provided a kind of regulation flushing water pump outlet pressure
Combustion engine compressor blade cleaning device, flushing water pump outlet pressure can be adjusted to suitable value, flushing water pump is run always
In stable operating mode, reduce the loss of flushing water pump, compared with low energy consumption.Voltage stabilizing regulation can also be needed to adjust according to pressure of supply water
The set-pressure of valve.
Realizing the technical solution of the utility model is：A kind of combustion engine compressor blade of regulation flushing water pump outlet pressure is clear
Cleaning device, including cleaning water tank, flushing water pump, cleaning Water flow adjusting valve and cleaning head assembly；The cleaning water tank passes through clear
The cleaned water pump of wash water pipeline, cleaning Water flow adjusting valve are connected to cleaning head assembly；It is characterized in that：Exported in flushing water pump
Controlling valve of voltage regulation is installed between cleaning water container backwater entrance.
The controlling valve of voltage regulation is parallel with bypass valve.
Cleaning water ga(u)ge is installed between the cleaning Water flow adjusting valve and cleaning head assembly.
The both ends of the cleaning Water flow adjusting valve are separately installed with rinse water pressure detecting instrument.
The cleaning head assembly includes rinse water feed water valve and cleaning sprayer.
The cleaning head assembly includes the on-line cleaning head assembly being installed in parallel and offline cleaning head assembly.
The on-line cleaning head assembly includes online rinse water feed water valve and on-line cleaning shower nozzle.
The offline cleaning head assembly includes offline rinse water feed water valve and offline cleaning sprayer.
The beneficial effects of the utility model are：
1st, the utility model is provided with controlling valve of voltage regulation between flushing water pump exports and cleaned water container backwater entrance, passes through
Controlling valve of voltage regulation pressure value is adjusted, the stable stable operation under a certain pressure of flushing water pump outlet pressure can be made（Such as specified pressure
Power）, ensure the stabilization of pressure of supply water.
2nd, either rinse water feed water valve is opened or closed, and the pressure of flushing water pump outlet can be stablized to be adjusted in voltage stabilizing
Valve set-pressure value is run.So, flushing water pump outlet pressure can be adjusted to suitable value, flushing water pump is operated in always
Stable operating mode, reduces the loss of flushing water pump, compared with low energy consumption.Regulation controlling valve of voltage regulation can also be needed according to pressure of supply water
Set-pressure.

Embodiment
As shown in Figure 1：A kind of combustion engine compressor blade cleaning device for adjusting flushing water pump outlet pressure, including rinse water
Case 1, flushing water pump 2, cleaning Water flow adjusting valve 6 and cleaning head assembly；The cleaning water tank 1 is cleaned by cleaning water lines
Water pump 2, cleaning Water flow adjusting valve 6 are connected to cleaning head assembly；Flushing water pump 2 export with clean water tank 1 backwater entrance it
Between controlling valve of voltage regulation 3 is installed.The controlling valve of voltage regulation is parallel with bypass valve 4.In the cleaning Water flow adjusting valve 6 and cleaning
Cleaning water ga(u)ge 5 is installed between head assembly.The both ends of the cleaning Water flow adjusting valve 6 are separately installed with cleaning water pressure
Detector PI.The cleaning head assembly includes the on-line cleaning head assembly being installed in parallel and offline cleaning head assembly.It is described online
Cleaning head assembly is included in line rinse water feed water valve 7 and on-line cleaning shower nozzle 9.The offline cleaning head assembly includes offline cleaning
Water feed water valve 8 and offline cleaning sprayer 10.
The course of work of the present utility model is：The pressure of controlling valve of voltage regulation 3 is adjusted, in plant running, flushing water pump 2 goes out
The pressure of mouth will stabilise at the set-pressure of controlling valve of voltage regulation 3.There are following two operating modes：
1st, the water for cleaning the inside of water tank 1 is pressurized by leaf cleaning water pump 2, by cleaning water ga(u)ge 5 and for on-line cleaning
Water feed water valve 7 or offline rinse water feed water valve 8 clean into combustion engine to compressor blade, the regulation cleaning of controlling valve of voltage regulation 3
The pressure that water pump 2 exports, if pressure reaches the setting valve of controlling valve of voltage regulation 3, controlling valve of voltage regulation 3 is opened, and part water is back to clearly
Water tank 1, closed when pressure declines controlling valve of voltage regulation 3.
2nd, water spray tempus intercalare, flushing water pump 2 continue to run with, on-line cleaning water feed water valve 7 or offline rinse water feed water valve 8
Close, the water that flushing water pump 2 is got all returns to cleaning water tank 1 by controlling valve of voltage regulation 3, if pressure reaches controlling valve of voltage regulation
3 setting valves, controlling valve of voltage regulation 3 are opened, and water is back to cleaning water tank 1, are closed when pressure declines controlling valve of voltage regulation 3.
Both the above situation realizes the stabilization of the outlet pressure of flushing water pump 2.In addition, when the pressure/stream for needing to spray water
When measuring changes in demand, it can also meet that rinse water feeds water by adjusting controlling valve of voltage regulation 3 again, in the case of equipment is not changed
Needs.Therefore in combustion engine compressor blade cleaning process, the stable operation of flushing water pump 2 is ensure that, is reduced to cleaning
The loss of water pump 2 and motor M, has saved the energy again.
