Abstract
The utility model relates to a ventilator for a water turbine. A spiral casing is arranged on a supporting frame which is fixed to a vane cover casing by a supporting rod, a water impeller and a wind impeller are fixed to both ends of a shaft, and the shaft is supported on a bearing seat sleeve by a bearing and an end cover. The utility model is characterized in that the upper end of the bearing seat sleeve is provided with a sealing sleeve whose upper end is provided with a vane guiding ring, and the vane guiding ring is contacted with the upper inner wall of the spiral casing. Because the spiral casing, the vane guiding ring and the sealing sleeve are all separate components, the utility model has convenient installing operation. Besides, the working gap of a working wheel can be quite exactly controlled in the desired range. The utility model has less working leakage loss and improved work efficiency.
Description
The utility model is a kind of ventilator, and it relates to a kind of waterpower blower fan, specially refers to a kind of hydroturbine ventilator.
In the prior art, do not find and the identical product of the utility model as yet, at present domestic only have the only a few boats and ships to use from a kind of M-2 type waterpower blower fan of Japanese WiNNERS company import, it comprises spiral case, water impeller, guide vane ring, front cover, stuffing box gland, fan blades etc. partly constitute, find that in actual use there is following shortcoming in this type blower fan: (1) is because of guide vanes of water turbine and spiral case integral cast, when if applying working condition changes, will make wooden model again, whole the spiral case of casting, economical inadequately, when adopting the sand casting process of less expensive, stator must be thickeied, stator must be thickeied, surface finishment is also uncontrollable, and when dismounting, must first pull down active wheel from front end, the operating space is little, and work is inconvenient.(2) the spiral case front end is compressed by a threaded front cover that seal ring sealed, and the last location of front cover is to be decided by the resiliently deformable of seal ring, for being worked reliably, running wheel do not wipe shell, will leave bigger space between impeller and the end cap, the leadkage loss of water turbine is strengthened, reduce working efficiency.
The purpose of this utility model just is to overcome the shortcoming of prior art, and the hydroturbine that a kind of fitting operation is more convenient and leadkage loss is little ventilator is provided.
The purpose of this utility model is achieved in that spiral case is installed on the bearing support, bearing support is fixed on the fan blade case by strut, working water impeller and fan blade are separately fixed at the two ends of axle by key, axle rides on the bearing sleeve by bearing and end cap, it is characterized in that: the upper end of bearing sleeve is provided with stuffing box gland, and dynamic seal apparatus is equipped with in stuffing box gland inside, and guide vane ring is installed in the upper end, the last inwall of spiral case contacts with guide vane ring, and lower wall is connected with the outward flange of stuffing box gland.
Because the utility model is provided with stuffing box gland, guide vane ring is installed in the upper end of stuffing box gland, its outward flange is connected with spiral case, so guide vane ring, spiral case, stuffing box gland is not integral cast, they are discrete components, when operating mode changes, as long as the transposing guide vane ring just can be realized the change of whole device ability to work, fitting operation is more convenient, working clearance owing to the working water impeller is not to compress seal ring by threaded front cover to decide simultaneously, guide vane ring is axially wide to be decided to wide difference with the working water impeller shaft but rely on, and it can be controlled in the required scope by machining more accurately.Therefore, the work leadkage loss is smaller, has improved working efficiency.
State concrete enforcement of the present utility model below in conjunction with the further lock of accompanying drawing.
Accompanying drawing is a kind of section of structure of the present utility model.
See also accompanying drawing, spiral case 1 is installed on the bearing support 8, bearing support 8 is fixed on the fan blade case 14 by strut 11, be equipped with filter screen 10 between case 14 and the strut 11, working water impeller 3 and fan blade 13 are separately fixed at the two ends of axle 2 by key, axle 2 rides on the bearing sleeve 7 by bearing 9 and end cap 12, stuffing box gland 6 is installed in upper end at bearing sleeve 7, dynamic seal apparatus 4 is equipped with in the inside of stuffing box gland 6, guide vane ring 5 is installed in the upper end, the inwall of spiral case 1 contacts with guide vane ring 5, the outward flange face of the lower wall of spiral case 1 and stuffing box gland 6 is fastening with screw, rely on like this guide vane ring 5 axially wide with axially wide poor of working water impeller 3, the working clearance of active wheel 3 accurately can be controlled at required scope, reduce the water turbine leadkage loss, improved efficient; Hub is opened the system screw thread in the fan blade 13, can use the drawing-die instrument during dismounting wind wheel, and is easy to operate; A boss is made at the card center drilling of guide vane ring 5 or the back side, when water impeller 3 is worked therein, can reduce the back side and radially sew, and further raises the efficiency, and guide vane ring 5 can be by machining or cast molding; The outer convex shoulder of stuffing box gland 6 has seal groove, front-end face has aperture and convex shoulder, guide vane ring 5 is able to circumferentially and radial location, there is convex shoulder stuffing box gland 6 rear ends, the bearing periphery is located, the periphery of stuffing box gland 6 has flange hole and is connected with spiral case 1 with realization, and stuffing box gland spacer flanger tapped hole is used for being connected with bearing support.Because the existence of stuffing box gland 6 has realized that guide vane ring 5 and spiral case 1 are separated.
Working principle of the present utility model is roughly as follows: after power water enters from the water inlet of spiral case 1, water is uniformly distributed in the periphery of guide vane ring 5 by spiral case 1, guide vane ring 5 makes water enter water impeller 3 with certain angle and promotes water impeller 3 and work done, and water is discharged from the water outlet of spiral case 1 then.Water impeller 3 rotates fan blade 13 by axle 2 synchronously.The rotation work done of fan blade 13 makes air-flow flow to the outlet of case 14 by the inlet of case 14 with certain flow and blast, thereby finishes the blower fan function.
Claims (2)
1, a kind of water worm gear ventilator, spiral case is installed on the bearing support, bearing support is fixed on the fan blade case by strut, working water impeller and fan blade by key be separately fixed at the axle two ends, the axle ride on the bearing sleeve by bearing and end cap, it is characterized in that: the upper end of bearing sleeve is provided with stuffing box gland, dynamic seal apparatus is equipped with in stuffing box gland inside, guide vane ring is installed in the upper end, and the last inwall of spiral case contacts with guide vane ring, and lower wall is connected with the outward flange of stuffing box gland;
