Background technique
Existing impeller assembly, impeller, rotating shaft are generally comprised, positioning seat, described impeller set is located at rotating shaft one end, and the other end of rotating shaft is plugged in positioning seat, also bearing is provided with between rotating shaft and positioning seat, be provided with fluid in described positioning seat, the rotating shaft being positioned at positioning seat is arranged with two groups of buffer substrate tablets, and buffer substrate tablet and positioning seat are directly welded and fixed, during work, control axis of rotation by external power source thus impeller rotation.When not using, this buffer substrate tablet is subject to the obstruction of fluid, can prevent impeller rotation well, and after cancelling power source, buffer substrate tablet is subject to the obstruction of fluid, and impeller can be made to stop operating fast.But, the impeller assembly of this structure, because buffer substrate tablet and rotating shaft are welded and fixed, therefore, it can not be changed, thus the drag size of fluid to buffer substrate tablet can not be changed, in different occasion, often need to change fluid to the drag size of buffer substrate tablet, control after cancelling power source, the time that impeller stops operating, therefore, this impeller assembly using scope is restricted.
Summary of the invention
The purpose of this utility model: in order to overcome the defect of prior art, the utility model provides a kind of impeller assembly, it can make buffer substrate tablet can dismantle, change, thus regulates fluid to the size of buffer substrate tablet resistance, and using scope is wide.
The technical solution of the utility model: a kind of impeller assembly, include impeller, rotating shaft, positioning seat, described impeller set is located at rotating shaft one end, the other end of rotating shaft is plugged in positioning seat, also bearing is provided with between rotating shaft and positioning seat, fluid is provided with in described positioning seat, the rotating shaft being positioned at positioning seat is arranged with two groups of buffer substrate tablets, it is characterized in that: rotating shaft sidewall offers two slots along its axial symmetry, two groups of buffer substrate tablets are plugged in slot respectively, often organize buffer substrate tablet and include several lamellar bodies axially set gradually along rotating shaft, one end that rotating shaft is positioned at positioning seat is provided with positioning spiro pit, positioning spiro pit and slot conducting, positioning screw is inserted with in positioning spiro pit, positioning screw is pressed on buffer substrate tablet.
Adopt technique scheme, when buffer substrate tablet is dismantled, can first positioning screw be screwed out, then, buffer substrate tablet is taken out in slot, when the size needing change fluid to buffer substrate tablet resistance, only need the quantity by changing lamellar body, it is simple to operate, and using scope is wide.
Further setting of the present utility model: described positioning seat includes pedestal, the end cap that split is arranged, and described pedestal is connected with end cap buckle, is provided with sealing configuration between described pedestal and end cap, and described bearing is arranged on end cap.
Adopt above-mentioned further setting, positioning seat split is arranged, and makes rotating shaft, the installation of buffer substrate tablet, convenient disassembly; Pedestal is connected with end cap buckle, makes its installation, convenient disassembly; The sealing configuration arranged, can prevent fluid from leaking, good airproof performance well.
Setting further more of the present utility model: described end cap is provided with positioning ring, the outer wall of described positioning ring is provided with locating bump, on described pedestal, corresponding locating bump position is provided with locating slot, and described locating bump is placed in formation pedestal in locating slot and is connected with the buckle of end cap.
Adopt and above-mentionedly to arrange further again, be placed in locating slot by locating bump and form pedestal and be connected with the buckle of end cap, structure is simple, processing, easy for installation.
Of the present utility modelly further to arrange again: described sealing configuration includes and on the outer wall of described positioning ring, is positioned at locating bump both sides is respectively equipped with seal groove, is embedded with seal ring in described seal groove.
Adopt and above-mentionedly further to arrange again, this sealing configuration, good airproof performance, can play double sealing effect.
