Abstract
The utility model discloses a high-efficient self priming pump, which comprises a pump body, an impeller, a pump shaft and a protective tube, wherein the pump shaft is installed on the pump body through the protective tube, the impeller is installed on one end of the pump shaft, a guide vane is installed in a gap between the outside of the impeller, the protective tube and the pump body, a plurality of evenly-distributed flow passages are arranged on the guide vane, a self priming process can be finished rapidly by the pump through multi flow passages powerful air and water separating effects, and self priming time can be shortened more than one third-a half compared with a conventional vertical type self priming pump. The pump is widely used in each industry as chemical industry, electric power, metallurgy, environmental protection, fire-fighting, construction, petroleum, mining, sewage disposal and the like.
Description
Technical field:
The utility model relates to a kind of self-priming pump, relates in particular to a kind of at widely used self-priming pumps of industry such as each chemical industry, electric power, metallurgy, environmental protection, fire-fighting, building, oil, mining, sewage treatments.
Technical background: improve the efficient of pump, reduce the power consumption of pump, reduce environmental pollution that the client causes because of the leakage of pump and be and fall over each other project and the problem developed in the pump industry at present.For a long time, owing to involving great expense of Under Water Pumps, easily damaged parts is many, and maintenance difficult and maintenance expenses are not low yet; In the diving submerged pump whole immersion medium, comprise motor, as little leakage takes place to cause big fault, even make entire pump be in paralysis.Therefore in industries such as chemical industry and sewage treatment, begin self-priming pump has been replaced above pump class, and at each chemical industry, electric power, metallurgy, environmental protection, fire-fighting, building, oil, mining, industries such as sewage treatment are extensive use of.Self-priming pump divides two kinds again, and a kind of is horizontal self-sucking pump, and a kind of is vertical self-sucking pump.The horizontal self-sucking pump import has safety check, and is fragile, and therefore the machine seal apparatus that uses is easy to generate leakage owing to be lower than liquid storage liquid level in the pump; Vertical self-sucking pump inlet has installed the ELECTROMAGNETIC VACUUM destructive valve and has drained liquid storage in the pump because of siphon when preventing to shut down; but this solenoid valve easily generates heat when working; life-span is short; if solenoid valve damages; to make self-priming pump lose self-absorption function; and this pump efficiency is very low, and matched power exceeds normal more than 50%, gives user's the very big cost that caused virtually.Thereby all can't reach the ideal effect of high-efficient energy-saving environment friendly simultaneously.
Summary of the invention:
The purpose of this utility model is exactly to be to avoid above-mentioned the deficiencies in the prior art part and high-efficient self-priming pump that a kind of new structure is provided, has the outstanding advantage of finishing the self-priming process fast.
The utility model is achieved in that a kind of high-efficient self-priming pump, comprise the pump housing, impeller, pump shaft and pillar, described pump shaft is installed on the described pump housing by pillar, end at described pump shaft is equipped with impeller, it is characterized in that: the space between described impeller outer survey, described pillar and the pump housing is equipped with stator, and described stator is provided with several equally distributed runners.
The utility model compared with prior art has following advantage:
Because the multithread road on described stator has powerful air-water separation effect, resembles many air exhauster, makes pump can finish the self-priming process fast, more than the short 1/3-1/2 of more conventional vertical self-sucking pump self-priming time.
Description of drawings:
Fig. 1 is the structural representation of high-efficient self-priming pump described in the utility model
1. the pump housing 2. impellers 3. stators 4. pillars 5. pump shafts 6. runners
Embodiment:
As can be seen from Figure 1, a kind of high-efficient self-priming pump, comprise the pump housing 1, impeller 2, pump shaft 5 and pillar 4, described pump shaft 5 is installed on the described pump housing 1 by pillar 4, end at described pump shaft 5 is equipped with described impeller 2, it is characterized in that: the space outside described impeller 2 between survey, described pillar 4 and the pump housing 1 is equipped with stator 3, and described stator 3 is provided with several equally distributed runners 6.
Adopt the waterpower design software to optimize runner waterpower on impeller, stator and the pump housing, improve pump performance, compare with conventional vertical self-sucking pump from their rationality of waterpower, pump efficiency improves 20%-30%, obvious energy conservation, 10%-15% at the bottom of the net positive suction head inhales the journey height.
