In said structure, impeller is closed type structure, and the pump housing, impeller, inducer, outer pump cover and interior pump cover all manufacture with 316L stainless steel, have both met requirement against corrosion, and have met hygienic requirements again.
The utility model compared with prior art, has following good effect:
1, the suction port of outer pump cover sets up inducer, and structure is simple, makes easily;
2, the inducer of helix structure rotates with pump shaft, directly increases impeller eye pressure, can alleviate cavitation erosion and intensity occurs, alleviate the spot corrosion to impeller blade surface, reduces running noises and the vibration of pump;
3, interior water-cooling structure, improves the working environment of mechanical seal and bearing, improves the working life of friction pair.
Accompanying drawing explanation
Fig. 1 is the utility model structural profile schematic diagram.
Fig. 2 is Fig. 1 left view.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
High temperature distillation water-circulating pump shown in Fig. 1, it is made up of jointly base 1, shaft coupling 10, motor 11 and pumping section.Described pumping section is based on the pump housing 2, and put the impeller 3 of closed type structure at the pump housing 2 inner chamber of horizontal type structure, the import of impeller 3 outwardly.The equipped outer pump cover 5 in exterior edge face of the pump housing 2, pump cover 6 in interior edge face is equipped, axially installs mechanical seal 7 in the middle part of interior pump cover 6.With the coaxial axle bed be connected 8 of interior pump cover 6 on base 1, pump shaft 9 stretches out from axle bed 8 two ends, and one end positioned in sequence towards the pump housing 2 installs mechanical seal 7, impeller 3.Pump shaft 9 towards the other end connects motor 11 by shaft coupling 10, forms and to be linked the drive mechanism that pump shaft 9 rotates by motor 11.Intensity is there is in the utility model in order to cavitate when slowing down pump operation, the inducer 4 that be connected coaxial with impeller 3 is provided with in the suction port inner chamber of outer pump cover 5, the inducer 4 of helix structure rotates with pump shaft 9, direct increase impeller 3 inlet pressure, the inlet pressure of impeller 3 improves can alleviate cavitation erosion generation intensity.The low spot corrosion directly alleviated impeller 3 blade surface of cavitation intensity in pump, also reduces running noises and the vibration of pump simultaneously.Mechanical seal 7 is arranged in the middle part of interior pump cover 6, leans against impeller 3, and mechanical seal 7 is positioned at the temperature impact being subject to two aspects herein, one is the temperature of carrying hyperthermal distilled water, two is heats that friction pair generates when rotating, so mechanical seal 7 work under bad environment, working time is long just lost efficacy.The utility model, in order to improve the working environment of mechanical seal 7, is installed the outer of mechanical seal 7 place at interior pump cover 6 and is arranged with water annulus 6.1, and the water annulus 6.1 closed is provided with the cooling water intake 6.2, the coolant outlet 6.3 that stagger position.The cooling water introduced takes away heat through water annulus 6.1, directly reduces the temperature of mechanical seal 7, improves running state.Long-time running, the temperature of axle bed 8 is also very high, although axle bed 8 penetrates heat transfer by the heat transfer of pump shaft 9 and the width of the pump housing 2, the ambient temperature of axle bed 8 is still very high, the lubricating oil that axle bed 8 is built-in is in high temperature environments thinning, easily pollute surrounding enviroment from the machine oil of slot leakage, even pollute the medium of transmission in pump, cause the problem that sanitary grade is not up to standard.The utility model is provided with inner lead 8.1 in supporting place of axle bed 8 bearings at both ends, and inner lead 8.1 two ends that inside communicates are respectively equipped with cooling water intake 8.2, coolant outlet 8.3.From the low-temperature cooling water that cooling water intake 8.2 is introduced during work, the cooling water heated up through heat exchange is discharged through inner lead 8.1, although water-cooling structure is simple in this kind, but cooling effect is fine, guarantee that the bearing that axle bed 8 is equipped with cause thermal damage did not occur, make the lubricating oil of adapted also can not be overheated thinning, thus can avoid internal leakage problem occurs.The present embodiment working medium is the distilled water of 100 DEG C.The product adopting said structure to make is supporting in evaporative type water generating machine peculiar to vessel, and can accomplish operation 9600 failure-free hours, this index exceeds nearly 2 times than prior art, greatly improves operational efficiency, reduces the supporting cost of user.The utility model is in order to accomplish that sanitary grade does not reduce, and manufactured by all flow passage components 316L stainless steels, concrete flow passage components have the pump housing 2, impeller 3, inducer 4, outer pump cover 5 and interior pump cover 6.Manufacture flow passage components with erosion resistant, although manufacture cost strengthens, sanitary grade is secure, failure rate is low, long service life, and because comprehensive benefit is good, the cost of material of increase can be ignored.
