Description
Technical field
The utility model relates to the adjustable washer jet of a kind of lobe pump, is mainly used in dust cleaning in lobe pump cavity.
Background technology
At present in metal smelt industry, the mode of vacuum metling is more and more widely used, in the process of smelting, motlten metal remains in vacuum environment, while venting, inert gas also to used to stir, therefore in vacuum metling overall process, have a large amount of dust to enter in Roots's pump housing and to deposit, in order to make lobe pump can stablize normal operation, the deashing in pump chamber is removed contamination becomes the key point of plant maintenance.But traditional purge mode has following shortcoming:
1) adopt compressed air to purge, purge coverage rate little, leave deashing dead angle;
2) adopt compressed air to purge, purge time is long, purges ash-removal effect poor;
3) compressed air is adopted to purge, in the pipeline of dust deposit bottom pump chamber or bottom pump chamber, cannot directly excavationg pump be external;
4), after in pump chamber, dust makes moist, compressed air purges and lost efficacy, cannot deashing;
5) pump chamber internal rotor due to dust stratification stuck after, compressed air purge lost efficacy, cannot deashing.
Therefore, traditional purge mode the deashing not being suitable for lobe pump are removed contamination.
Utility model content
The technical problem that the utility model solves is the above-mentioned defect overcoming prior art, and the adjustable washer jet of lobe pump providing a kind of structure simple, stable, efficient, safe.
The utility model solves the problems of the technologies described above adopted technical scheme: the adjustable washer jet of a kind of lobe pump, it is characterized in that being provided with nozzle barrel, cut-out governing ring, nozzle body, main jet loophole and auxiliary jet, nozzle barrel and cut-out governing ring are integrally fixed, cut-out governing ring is connected with nozzle body, nozzle barrel top is connected with feed pipe, the upper chamber of nozzle barrel is communicated with main jet loophole, main jet loophole flare, described upper chamber is communicated with the lower cavity of nozzle barrel by the throttle orifice on cut-out governing ring, lower cavity has auxiliary jet, lower cavity forms the annular spray face of 360 degree.
Nozzle body described in the utility model is connected with cut-out governing ring by screw thread, by rotating nozzle body, nozzle body can be made to promote or decline, thus the spray angle of the height of adjustable main jet, auxiliary jet and flow.
Cut-out governing ring described in the utility model is two.
Nozzle body described in the utility model has center culvert, and center culvert is connected with cut-out governing ring by screw thread.
Nozzle barrel top described in the utility model is connected with feed pipe by screw thread.
The utility model have structure simple, stable, efficiently, safely, the feature such as effective of removing contamination.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the schematic top plan view of Fig. 1.
In figure: 1-nozzle barrel, 2-cut-out governing ring, 3-nozzle body, 4-main jet loophole, the auxiliary jet of 5-, 6-upper chamber, 7-throttle orifice, 8-lower cavity.
Detailed description of the invention
See Fig. 1, Fig. 2, the adjustable washer jet of the utility model embodiment lobe pump comprises nozzle barrel 1, cut-out governing ring 2, nozzle body 3, is provided with main jet loophole 4 and auxiliary jet 5.Nozzle barrel 1 top is connected with feed pipe by screw thread, two-way is divided into after water enters nozzle barrel 1 upper chamber 6, center culvert 9 of leading up to is communicated to main jet loophole 4, is formed on rotor that tubaeform jet face is ejected in pump chamber, can cover rotor surface completely; The throttle orifice 7 of leading up on cut-out governing ring 2 enters lower cavity 8, the annular spray face of one 360 degree is formed by auxiliary jet 5, be ejected on housing in pump chamber and end cap, housing and end cap form water curtain and discharges from top to bottom, reach the cleaning performance covering cavity inner surface completely.Because various brands lobe pump cavity body structure exists certain difference, in order to make nozzle, there is versatility, main jet loophole 4 and auxiliary jet 5 is allowed to possess best jetting height and angle, nozzle body 3 is designed to adjustablely move up and down formula, nozzle body 3 is threaded connection and is arranged on two cut-out governing rings 2, by rotating nozzle body 3, nozzle body 3 can be made to promote or decline, thus the spray angle of the height of adjustable main jet 4, auxiliary jet 5 and flow.By arranging throttle orifice 7 on cut-out governing ring 2, the minimum injection flow of main jet loophole 4 can be ensured, thus ensure that the effect of removing contamination of main jet loophole 4.
The equivalent transformation of every technical solutions of the utility model and technical characteristic or combination, all should think and fall into protection domain of the present utility model.
