Abstract
The utility model relates to a blade full regulator for a vertical water pump, which comprises an operating rod (1), a first bearing (11), a second bearing (13), a bearing water cooling cavity (100) and a sealing device (120), wherein the first bearing (11) and the second bearing (13) are arranged at the side of the operating rod (1); the bearing water cooling cavity (100) is arranged at the side of the first bearing (11) and the second bearing (13); and the sealing device (120) is arranged on an oil retaining sleeve (110). The utility model has the advantages that the installation is convenient; the service life of the bearing is prolonged through the additional arrangement of the water cooling cavity; the oil retaining sleeve structure is improved, the sealing device is additionally arranged on the regulator, so the regulator has no oil leakage; and the selection of a regulating motor is not limited by space dimension, the structure is simplified, and the reliability of the regulator is obviously improved.
Description
Technical field
The utility model relates to a kind of vertical water pump, relates in particular to the wheel member controlling mechanism of this pump.
Background technique
The 16CJ80 that produces the seventies regulates axial-flow pump entirely and has adopted solid shaft motor, the full controlling device of mechanical type blade.This type pump is that important function has been played in the development of China's farmland discharging-irrigating cause.Yet one of common problem that exists is that the adjusting action of blade is reliable inadequately.
Such as: cities and towns water drainage rainfall pumping station and irrigation and drainage pumping station, because the raising year by year of river level, the lift of the pumping plant in past is on the low side all in flow operation less than normal, waits for transformation, newly-built irrigation and drainage pumping station need select for use lift and flow adjustable, and pump is being moved under efficient operating mode;
The north diversion works, east line, western line and center line three large-engineerings are that flow is big, need the continuous conveying of flows such as a plurality of pumping plants on the circuit, need select for use much reliable can be the pump of Signal Regulation flow with water level between water inlet again, and the pump at each station of the East Route Project that has built up at present, owing to there is not adjustable pump optional, has to adopt a pumping plant to select many pumps for use and reach the requirement that waits the continuous conveying of flow with the quantity of manual operation process pump.
As seen from Figure 1: pass through key 8 by cycloidal planetary gear speed reducer 9 and be connected with adjusting screw rod 7, the mechanism that forms by adjusting screw rod 7 and the screw pair drive adjusting nut cover 4 and the operating stem 1 of adjusting nut 5 compositions moves up and down, thus the realization angle adjustment.Adjusting nut 5 and adjusting nut cover 4 is connected by bolt 6, feather key 3 is fixing with adjusting nut cover 4 by bolt 2, thereby when cycloidal-pin wheel 9 clockwise rotates the adjusting parts are moved up by feather key, drive the parts integral body of forming by adjusting screw rod 7 and water pump vane parts controlling mechanism and move up; But the spring in the controlling mechanism (10,12) is installed complicated; What bearing (11,13) adopted is natural air cooled, and cooling effect is poor, thereby causes bearing to move the working life that has shortened bearing under continuous high temperature, has also increased the maintenance difficulty of equipment; Retaining oil jacket 14 can cause wearing and tearing to make in actual moving process and cause seal failure because structure is outmoded, causes the thin oil in the bearing bore to leak.
Summary of the invention
The utility model technical issues that need to address have provided a kind of vertical water pump with the full controlling device of blade, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: operating stem is placed in operating stem the side other clutch shaft bearing and second bearing; Also comprise: one is placed in clutch shaft bearing and the other bearing waterway of the second bearing side; A seal arrangement is placed on the retaining oil jacket.
Compared with prior art, the beneficial effects of the utility model are: it is convenient to install; The design that has increased waterway prolongs the working life of bearing; Improving retaining oil jacket structure increases seal arrangement, can not make the leakage of oil of adjusting machine; Regulate the restriction that is not subjected to bulk with selecting for use of motor, simplify the structure, significantly improved the reliability of device action.
Description of drawings
Fig. 1 is a water pump vane parts controlling mechanism schematic representation in the prior art;
Fig. 2 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 2: the utility model comprises: operating stem 1 is placed in operating stem 1 the side other clutch shaft bearing 11 and second bearing 13; Also comprise: one is placed in clutch shaft bearing 11 and the other bearing waterway 100 of second bearing, 13 sides; A seal arrangement 120 is placed on the retaining oil jacket 110.
In order to make the versatility of adjusting machine component, the utility model keeps structure constant to component 1-9 on the original basis, the improvement part component structural, thus avoid above-mentioned defective.The utility model has been cancelled spring (10,12); Increased the design of bearing waterway,, made the adjusting machine in running, the consequence that bearing heating causes the adjusting machine not move can not occur, prolonged the working life of bearing simultaneously, also reduced maintenance frequency by cooling water lubrication; Problem the utility model at leakage of oil has increased seal arrangement.
Design principle of the present utility model has been considered 2 points simultaneously except improving emphatically the reliability: one, and regulate the axial force that produces and still bear by main motor shaft; Its two, the axial dimension of controlling device is constant substantially.
The implementation procedure that the utility model is regulated action is, be connected with adjusting screw rod 7 by key 8 by cycloidal planetary gear speed reducer 9, the mechanism that forms by adjusting screw rod 7 and the screw pair drive adjusting nut cover 4 and the operating stem 1 of adjusting nut 5 compositions moves up and down, thus the realization angle adjustment.Adjusting nut 5 and adjusting nut cover 4 is connected by bolt 6, feather key 3 is fixing with adjusting nut cover 4 by bolt 2, thereby the adjusting parts are moved up by feather key when cycloidal-pin wheel 9 clockwise rotates, the parts integral body that drive is made up of adjusting screw rod 7 and water pump vane parts controlling mechanism moves up, blade is regulated to positive-angle, otherwise regulated to negative angle.
The utility model and original comparing, main feature is: it is convenient to install; The design that has increased waterway prolongs the working life of bearing; Improving retaining oil jacket structure increases seal arrangement, can not make the leakage of oil of adjusting machine; Regulate the restriction that is not subjected to bulk with selecting for use of motor, simplify the structure, significantly improved the reliability of device action.Regulate the restriction that is not subjected to bulk with selecting for use of motor, simplify the structure, significantly improved the reliability of device action.Former controlling device axial length 750mm, new controlling device axial length 790mm.For the transformation of old pumping plant, the difference of 40mm is not difficult to remedy.Through overtesting, new controlling device maximum axial adjustable range 70mm, axial adjustment reaches 30KN, and it is as follows to see contrast table for details:
