Abstract
A device for cleaning turbine stationary blades by spring spraying comprises two semicircular spring spraying pipes with the same radius, wherein a water inlet pipe is arranged on each spring spraying pipe, water spraying holes are formed in the positions corresponding to the stationary blades along the circumference, and pipe holes at two ends of each spring spraying pipe are sealed by plugs. When in use, a device for cleaning the turbine static blades by spring spray is arranged in front of each stage of static blades. The spring nozzle can be a round pipe, an oval pipe, a rectangular pipe, and preferably a rectangular pipe. Use the device can carry out high-efficient washing to the quiet leaf when turbomachinery moves, avoids the passageway to block up, makes the unit ability high efficiency operation.
Description
Technical field
The utility model relates to a kind of device that cleans the turbine stator blade.
Background technique
Promote the working medium of large-scale turbomachinery rotation, often dust content composition big or salt is more, thereby dust stratification or analyse salt easily on each stator blade; cause passage to stop up; cause the unit can't high-efficiency operation, even overhauled the dust stratification on the water flushing stator blade by forced-stopping machine.Practice shows that main frame is taken off lid maintenance trouble, and the time of delaying is longer.Especially under the situation that dust content composition very big or salt is very many in the working medium, the cycle of shutting down maintenance is very short, can bring bigger economic loss to the user.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the device that provides a kind of spring spray formula to clean the turbine stator blade is installed this kind device on turbine stator blade inner housing, can carry out automatical and efficient cleaning to stator blade when turbomachinery moves.
Spring spray formula described in the utility model is cleaned the device of turbine stator blade, the spring jet pipe that comprises the semi-round ring shape that two radiuses are identical, on the described spring jet pipe intake pipe is installed, is provided with hole for water spraying along circumference in the position of corresponding each stator blade, the pore at its two ends is sealed by plug.During use, the device that a spring spray formula cleaning turbine stator blade is installed before every grade of stator blade gets final product.
The spring jet pipe can be a pipe, elliptical tube, rectangular tube, preferred rectangular tube.
In order to prevent that hole for water spraying from stopping up, hole for water spraying is tilted to down setting, inclination alpha is 30 °～60 °, the aperture is 3mm～5mm.
In order to guarantee that the water inlet outside casing does not let out from the hole of stator blade inner housing, the intake pipe outer wall of installing on the spring jet pipe is provided with seal ring.
Installation is integrally welded with plug and spring jet pipe for convenience, and is provided with the lug that is connected with turbine stator blade inner housing in a side of plug.
The utlity model has following beneficial effect:
1, uses device described in the utility model; can when moving, efficiently clean turbomachinery stator blade; thereby avoided the passage obstruction; make unit energy high-efficiency operation; even under the situation that dust content composition very big or salt is very many in working medium; can guarantee that also the unit long period normally moves, increase the cycle of shutting down maintenance.
2, simple in structure, be easy to processing and fabricating.
3, hole for water spraying is tilted to down setting, can prevent that hole for water spraying from stopping up.
4, the structure of plug can not leaked by shutoff spring water spray, provides fixed mechanism for the spring jet pipe is fixed on the stator blade inner housing again.
5, can spray liquid medicine, in and dust stratification in harmful matter, remove obstinate dust stratification.
