Abstract
The utility model relates to a high-efficiency non-reflux submersible pump with stripping function, which belongs to the technical field of a liquor pump. In order to solve the problems that when oil is discharged from a centrifugal oil-immersed pump which is provided with a sweeping cavity, a swirl is generated, the oil is sucked slowly, and the oil flows backwards after the cavity is swept; an annular cover plate is arranged outside an oil suction opening of the centrifugal pump, and a self-priming pump is arranged below the oil suction opening; a rotary shaft of a hydraulic motor is shared by an impeller of the self-priming pump and an impeller of the centrifugal pump; a casing of the self-priming pump is fixed on the lower end surface of the annular cover plate of the centrifugal pump through a support, and a check valve is arranged on an oil-discharging guide tube of the self-priming pump; thus, the high-efficiency non-reflux submersible pump with stripping function is formed. When the high-efficiency non-reflux submersible pump with stripping function is used for sucking the oil, the oil can be quickly sucked and the reflux can not generate after the cavity is swept.
Description
Technical field:
The utility model belongs to the liquid pump field.
Technical background:
At present in China's RTC unloading, the oil-immersed pump in storehouse has appearred sweeping, this pump is to install a Vortex pump additional in former centrifugal discharge pump inlet port supporting foot, and oil outlet connects flexible pipe and passes in the fuel-displaced mouth of pipe of centrifugal pump, so, the inlet port of former centrifugal pump and oil outlet space just can dwindle greatly, and oil absorption just can significantly reduce in the unit time, and the corresponding emptying time can prolong greatly.In addition, Vortex pump places in the centrifugal pump inlet port supporting foot, because the supporting foot internal volume is original just little, the Vortex pump impeller also will be very little like this, oil absorption also can be very little, use for a long time when sweeping the storehouse, and swept behind the storehouse it and swept that oil product also can flow backwards in the transport pipe of storehouse, sweep the storehouse like this and just can not thoroughly carry out.In addition, this kind oil-immersed pump can produce whirlpool around the pump case when oil suction, just cisco unity malfunction of centrifugal pump after the suck air.
The model utility content:
The purpose of this utility model provides a kind of efficient height, does not produce whirlpool, and sweeps the high-efficiency non-reflux submersible pump with stripping function that can not reflux behind the storehouse.
The technical solution adopted in the utility model is: at centrifugal pump inlet port arranged outside one annular cover plate, but the self-priming pump of an exhaust is set below cover plate, the shared oil hydraulic motor rotating shaft of self-priming pump impeller and centrifugal pump impeller, the self-priming pump impeller diameter should be not less than the inlet port diameter of centrifugal pump, and at self-priming pump oil outlet place a safety check is set.Like this, centrifugal pump inlet port place can not produce whirlpool after cover plate has been arranged, can many oil suctions, and, the self-priming pump impeller not only can be done greatlyyer, also withdrawing oil does not take centrifugal pump oil suction and fuel-displaced space, and this just can realize quick oil suction, sweep storehouse and do not have the high-efficiency non-reflux submersible pump with stripping function of withdrawing oil fast.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.Among the figure: 1-oil hydraulic motor, 2-mechanical seal, 3-centrifugal pump impeller, 4-centrifugal pump pump case upper end cap, 5-oil hydraulic motor transmission shaft, 6-annular cover plate, 7-self-priming pump impeller, 8-connects supporting post, and 9-returns only valve, 10-self-priming pump liquid outlet, 11-self-priming pump pump case, 12-self-priming pump inlet port, the sealing of 13-self-priming pump, 14 self-priming pump catheters.
Embodiment:
As shown in the figure, oil hydraulic motor 1 is fixed on the centrifugal pump pump case upper end cap, centrifugal pump impeller 3 is fixed on the rotatingshaft 5 of oil hydraulic motor 1, seal with mechanical seal 2 between rotatingshaft 5 and impeller 3 and the pump case upper end cap 4, cast out annular cover plate 6 during with centrifugal pump pump case integrally casting, the rotatingshaft 5 of oil hydraulic motor 1 extends downwards, self-priming pump impeller 7 is fixed on the rotatingshaft after the extension, the shared rotatingshaft 5 of centrifugal pump impeller and self-priming pump impeller, sealed 13 sealings between self-priming pump pump case 11 and transmission shaft 5 and the impeller 7, self-priming pump pump case 11 is fixed together by connecting supporting post and centrifugal pump suction port annular cover plate 6, the inlet port 12 of self-priming pump is arranged on the outside, lower end of self-priming shell, 10 places establish self-priming pump catheter 14 at the self-priming pump liquid outlet, on catheter 14, add to reinstall and end valve 9, so just formed high-efficiency non-reflux submersible pump with stripping function.During use, the liquid outlet and the liquid of immersed pump unloaded that the liquid entering hole of oil filling riser docks and fixing after, self-priming pump catheter 14 drawn along the oil filling riser vertical tubes of unloading and along unloading oil filling riser outer arm, inner arm up to unloading on the liquid pipeline.After immersed pump enters in the tank car jar with the oil filling riser vertical tube of unloading, the primer fluid pressure motor, at this moment pot liquid just is sucked out from centrifugal pump and self-priming pump two-way, because the effect of centrifugal pump suction port annular cover plate is arranged, liquid can't form whirlpool around the centrifugal pump suction port, centrifugal pump imbibition as often as possible like this, when tank level is low to moderate centrifugal pump can't imbibition the time, even utilize self-priming pump continue imbibition to the oil filling riser liquid in pipe return tank of unloading after, pot liquid is still outside centrifugal pump imbibition scope the time, the work of stop solution pressure motor, the liquid return that makes the oil filling riser pipe internal memory of unloading is in the tank car jar.Therefore primer fluid pressure motor once more because the self-priming pump impeller can be done greatlyyer, has that the self-priming pump of degassing function is just very fast to exhaust the liquid in the tank car jar.Owing to only valve is housed back on the self-priming pump oil guide pipe,, has so just realized high-efficiency non-reflux submersible pump with stripping function after oil hydraulic motor quits work even the liquid in the self-priming pump conduit can not flow backwards yet.
Claims (1)
- A kind of high-efficiency non-reflux submersible pump with stripping function, it is characterized in that at centrifugal pump liquid sucting port arranged outside one annular cover plate, the cover plate lower end connects a self-priming pump by supporting post, the shared oil hydraulic motor rotating shaft of self-priming pump impeller and centrifugal pump impeller, self-priming pump liquid outlet connect takes back the only catheter of valve.
