Abstract
The utility model discloses a liquid outlet device of a self sucking pump. The liquid outlet device consists of an impeller, a liquid outlet U-shaped device and a volute casing, wherein the volute casing is arranged in the pump body; the impeller is arranged in an inner chamber formed by the volute casing and a rear cover and is communicated with a liquid inlet pipe passing through the left lower part of the pump body; and the liquid outlet U-shaped device is arranged on the right of the pump body. The utility model can reduce the axial length of the self sucking pump by 0.2 to 0.5m and the corresponding height of the pump body, reduce cost investment, greatly reduce the axial force and radial force during operation, prolong the service life of the whole machine, reduce the maintenance rate and be suitable for self sucking pumps having a large calibre and large power.
Description
Technical field: the utility model relates to pump, particularly relates to a kind of liquid outlet device of self-priming pump.
Background technique: at present, traditional self-priming pump liquid outlet device adopts the standard round pipe bend to connect, and when design water pump spindle length and pump housing height, take into full account the shared position of liquid inlet pipe and drain pipe, highly.Be so limited, the shaft length of traditional self-priming pump and pump housing height can not shorten, and motor bears during running axial force and radial force are big, fragile electric motor end cap and bearing during long-play, and certain waste is also arranged on the input of material.
Summary of the invention: the purpose of this utility model is exactly the liquid outlet device that a kind of self-priming pump will be provided, and it can overcome the existing problem of existing self-priming pump liquid outlet device well.The purpose of this utility model is to realize like this, the liquid outlet device of self-priming pump is made up of impeller, liquid outlet U type device, volute, it is characterized in that: be provided with volute in the pump housing, be provided with impeller in the inner chamber that volute and bonnet form, and communicate with the liquid inlet pipe that passes pump housing left bottom; Described pump housing the right is provided with liquid outlet U type device.The utility model can shorten self-priming pump shaft length 0.2-0.5m and pump housing corresponding height, has reduced the input of cost, and has significantly reduced axial force and radial force when turning round, in the working life of having improved complete machine, has reduced maintenance rate.Be applicable to heavy caliber, powerful self-priming pump.
Description of drawings:
Fig. 1 is the utility model structural representation;
1. base plate, 2. drain, 3. liquid inlet pipe, 4. impeller, 5. liquid outlet U type device, 6. volute, 7. butterfly shaped check valve, 8. sealing impeller, 9. pump shaft, 10. support, 11. motors, 12. electrically-controlled valve.
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;
The liquid outlet device of self-priming pump is made up of impeller 4, liquid outlet U type device 5, volute 6, it is characterized in that: be provided with volute 6 in the pump housing, be provided with impeller 4 in the inner chamber that volute 6 and bonnet form, and communicate with the liquid inlet pipe 3 that passes pump housing left bottom; Described pump housing the right is provided with liquid outlet U type device 5.During concrete enforcement; with traditional liquid outlet pipe device; use the liquid outlet U type device of the utility model design instead; can shorten self-priming pump shaft length 0.2-0.5m and pump housing corresponding height; axial force and radial force that motor bears have been significantly reduced; not only protect electric motor end cap and bearing, reduced maintenance rate, improved the working life of complete machine again.
