Description
Technical field
The present invention relates to a kind of assistant tool of water system maintenance centrifugal pump, specifically a kind of large-scale one-stage centrifugal pump impeller dismounting platform.
Background technique
When maintenance at present or replacing one-stage centrifugal pump impeller all is to lay down pump cover, bearing upper press cover, hangs out impeller, axle, axle sleeve and bearing integral with leading chain mechanism, is placed on and dismantles impeller on the floor, owing to be the single-stage impeller; Pump shaft teetertotters during the dismounting impeller, rolls about impeller, can not be with taking off draft gage during the dismounting bearing; Can only strike with hammer, be easy to strike bearing bad, dismounting also is to strike with hammer during impeller; Impeller is easy to strike bad, and during because of dismounting bearing and impeller, the pump shaft one end the other end that contacts to earth is sticking up; Also be easy to bend pump shaft damage or sled, and waste time and energy inefficiency.
Summary of the invention
The purpose of this invention is to provide a kind of large-scale one-stage centrifugal pump impeller dismounting platform, overcome the defective that above-mentioned prior art exists.
The present invention includes impeller embedded body, impeller up-down holder, foot-operated or hand-operated oil hydraulic pump, impeller embedded body supporting frame and roller; It is characterized in that the impeller embedded body is made as half prismatic body or cuboid; Fore-and-aft direction is provided with the space of putting into two lobe impellers in half prismatic body; Be welded with curve bath semicylinder up separately at impeller embedded body left end and right-hand member; Being welded with a top two semicylinder bottoms is triangle frame, and bottom is the impeller embedded body supporting frame of rectangle rack, on four angles of rectangle rack, is provided with roller; In the impeller embedded body, be provided with a crescent moon slot type impeller on the fore-and-aft direction of middle and lower part and go up and down to hold in the palm, impeller up-down holder links to each other with hydraulic piston, and oil hydraulic cylinder is connected in the stull of rectangle rack, and links to each other with foot-operated or hand-operated oil hydraulic pump.
The present invention has solved large-scale one-stage centrifugal water pump vane security civilization dismounting problem preferably; Prevented the damage of pump shaft, impeller and bearing in disassembly process; Saved maintenance cost; Having improved working efficiency, is the assistant tool that is worthy of popularization of large-scale one-stage centrifugal water pump of dismounting or centrifugal oil pump.
Description of drawings
Accompanying drawing-structural representation of the present invention;
1-impeller embedded body among the figure, the 2-semicylinder, 3-impeller embedded body supporting frame, the 4-roller, the foot-operated oil hydraulic pump of 5-, the 6-oil hydraulic cylinder, the 7-impeller goes up and down to hold in the palm.
Embodiment
For further disclosing technological scheme of the present invention, elaborate through embodiment below in conjunction with Figure of description:
The present invention includes impeller embedded body, impeller up-down holder, foot-operated or hand-operated oil hydraulic pump, impeller embedded body supporting frame and roller; It is characterized in that the impeller embedded body is made as half prismatic body or cuboid; Fore-and-aft direction is provided with the space of putting into two lobe impellers in half prismatic body; Be welded with curve bath semicylinder up separately at impeller embedded body left end and right-hand member; Being welded with a top two semicylinder bottoms is triangle frame, and bottom is the impeller embedded body supporting frame of rectangle rack, on four angles of rectangle rack, is provided with roller; In the impeller embedded body, be provided with a crescent moon slot type impeller on the fore-and-aft direction of middle and lower part and go up and down to hold in the palm, impeller up-down holder links to each other with hydraulic piston, and oil hydraulic cylinder is connected in the stull of rectangle rack, and links to each other with foot-operated or hand-operated oil hydraulic pump.
When application is of the present invention; With the dismounting model is that the impeller of the centrifugal water pump of OMEGA250-480A is an example, pulls down pump cover and bearing upper cover, slings impeller, pump shaft and bearing integral with leading the chain elevator mechanism; Shift single-stage water pump vane dismounting platform onto the pump seat front; Put into impeller embedded body middle part to impeller, the pump shaft two ends are placed in the curve bath of semicylinder, make bearings at both ends be exposed at the outside of semicylinder.Shift impeller dismounting platform onto convenient place of working, fix roller, lay down bearing with taking off draft gage earlier, unload sleeve nut again; Unload loose axle sleeve, with the grapple of taking off draft gage, catch impeller embedded body supporting frame, draft gage middle top thick stick is grabbed in rotation; Keyway on the impeller is deviate from the key on the pump shaft, and rise impeller up-down holder with foot-operated or hand-operated oil hydraulic pump and hold up impeller this moment, extracts axle sleeve and pump shaft out, takes off impeller at last; Promptly accomplish impeller demolition work, if mounted impeller is put into impeller in the impeller up-down holder earlier; Insert pump shaft, the keyway of impeller is combined with key on the pump shaft, overlap Upper shaft sleeve; The axle sleeve nut of screwing on is installed the bearings at both ends of pump shaft, promptly accomplishes the installment work of impeller.
