Description
Technical field
The utility model relates to a kind of rotor pump, is specifically related to a kind of multi-level cam rotor pump, belongs to pump housing technical field.
Background technique
At present, the general lift of the lobed rotor pump that market uses is within 80 meters, and within lift 80 meters, common lobed rotor pump usability is more stable.But lift is more than 80 meters, 100 meters or 200 meters when, lobed rotor pump will produce powerful vibrations, make the inner each superstructure loosening of pump, mechanical seal is impaired, and high-lift lower medium refluxes rapidly in pump chamber, cause the volumetric efficiency of pump greatly to reduce, electric current increases.Therefore, it is high that high-lift lobed rotor pump use creates maintenance cost, consumes energy high, the series of problems that the life-span is low.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of novel multi-level cam rotor pump, to overcome described defect of the prior art.
Model utility content
For solving the problems of the technologies described above, the purpose of this utility model is a kind of high-lift, high energy-conservation, low cost and the multi-level cam rotor pump not easily shaken.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of multi-level cam rotor pump, and it comprises pump cover, first pump housing, second pump housing, the 3rd pump housing, gear-box, driving shaft, driven shaft, cam impeller and wear-resisting positioning plate; Wherein, described pump cover, first pump housing, second pump housing, the 3rd pump housing, gear-box are arranged successively; Described driving shaft, driven shaft are all supported on pump cover and gear-box, and driving shaft and driven shaft are respectively equipped with a synchromesh gear, and this two synchromesh gear is meshed; Described cam impeller is installed on driving shaft and driven shaft respectively, and is equipped with pair of cams impeller in first pump housing, second pump housing, the 3rd pump housing; Described wear-resisting positioning plate is arranged at the both sides in first pump housing, second pump housing, the 3rd pump housing respectively.
Multi-level cam rotor pump of the present utility model is set to further: be provided with an import in described first pump housing, it is connected by the first connecting tube with second pump housing; Described 3rd pump housing is provided with an outlet, and it is connected by the second connecting tube with second pump housing.
Compared with prior art, the utility model has following beneficial effect:
1. high-lift: more than 100 meters or 200 meters, to adopt multistage cam follower to make pump discharge preserve stable in the equal downforce of flow.
2. high energy-conservation: to keep reducing more than 30% when pressure than the multiple driving heads adopted in the past.
3. low cost: adopt single driving head to drive the transmission of many cover cam followers to greatly reduce manufacturing cost.The high pressure of high-lift lower pump chamber decomposes the wearing and tearing greatly reducing easily damaged parts in multiple pump chamber.
4. not easily shake: by wear-resisting positioning plate supporting driving shaft, driven shaft, thus make the good stability of this rotor pump.
Accompanying drawing explanation
Fig. 1 is the principal section figure of multi-level cam rotor pump of the present utility model.
Fig. 2 is the plan view of multi-level cam rotor pump of the present utility model.
Fig. 3 is the sectional drawing along A-A in Fig. 2.
Embodiment
Refer to shown in Figure of description 1 to accompanying drawing 3, the utility model is a kind of multi-level cam rotor pump, and it is made up of a few parts such as pump cover 1, first pump housing 2, second pump housing 3, the 3rd pump housing 4, gear-box 5, driving shaft 6, driven shaft 7, cam impeller 8 and wear-resisting positioning plates 9.
Wherein, described pump cover 1, first pump housing 2, second pump housing 3, the 3rd pump housing 4, gear-box 5 are arranged successively.Be provided with an import 10 in described first pump housing 2, it is connected by the first connecting tube 11 with second pump housing 3; Described 3rd pump housing 4 is provided with an outlet 12, and it is connected by the second connecting tube 13 with second pump housing 3.
Described driving shaft 6, driven shaft 7 are all supported on pump cover 1 and gear-box 5, and driving shaft 6 and driven shaft 7 are respectively equipped with a synchromesh gear 14, and this two synchromesh gear 14 is meshed, thus realizes the interlock of driving shaft 6, driven shaft 7.
Described cam impeller 8 is installed on driving shaft 6 and driven shaft 7 respectively, and is equipped with pair of cams impeller 8 in first pump housing 2, second pump housing 3, the 3rd pump housing 4.
Described wear-resisting positioning plate 9 is arranged at the both sides in first pump housing 2, second pump housing 3, the 3rd pump housing 4 respectively.
The working principle of multi-level cam rotor pump of the present utility model is as follows: drive driving shaft 6 to rotate by unit head system (not shown), driven the synchromesh gear 14 in driven shaft 7, driving shaft 6 and driven shaft 7 are rotated simultaneously by the synchromesh gear 14 in driving shaft 6.Rotate driving shaft 6, driven shaft 7 at the same time, drive the identical cam impeller 8 in first pump housing 2, second pump housing 3, the 3rd pump housing 4.Medium is sucked by import 10, the first connecting tube 11 is outputted to by the cam impeller 8 of first pump housing 2, be input in second pump housing 3 by the first connecting tube 11, the second connecting tube 13 is outputted to by the cam impeller 8 in second pump housing 3, be input in the 3rd pump housing 4 by the second connecting tube 13, output to outlet 12 by the cam impeller 8 of the 3rd pump housing 4 and be transported in corresponding pipeline.
Multi-level cam rotor pump of the present utility model separates three isolation pump chambers on same set of driving shaft 6, driven shaft 7, and the cam impeller 8 that in each pump chamber, each installation is same, makes three cover cam impellers 8 under same set of drive axis, and while works in each pump chamber.By the transmission of the cam impeller 8 in first pump housing 2 medium transport given the cam impeller 8 in second pump housing 3, carry out so successively.Because lobed rotor pump is the displacement pump of positive discharge capacity, flow and the rotating speed of pump are directly proportional, cam impeller 8 in multiple pump chamber works under the same transmission rotating speed of same set of transmission shaft, flow remains unchanged, make the pressure in second pump chamber be two times of first pump chamber, thus make to require that pressure is divided equally at multiple pump chamber.
Above embodiment is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
