Abstract
The utility model discloses a two branches of modified impeller for impeller pump, including upper cover plate, lower apron and setting up at upper cover plate and the middle blade device of apron down. The blade device is three connecting portion and constitutes, the one end of connecting portion sets up the lobus sinister piece, and the other end of connecting portion sets up the lobus dexter piece. Lobus sinister piece and lobus dexter piece are curved round ARC blade to same direction. The inner wall of connecting portion sets up the screens and sticks out, and three screens salient is used for connecting the transmission shaft of fixed impeller. The utility model discloses a designing two sets of blade combination work, when preventing that a blade is impaired, can also continuing to move a period, prevent that the impeller from can not move in the check under the impaired circumstances of operation, the sufficient time is reserved in maintenance and change for unloading.
Description
Technical field
The utility model relates to the manufacturing technology field of industrial pump, especially relates to a kind of two points of blade impeller of pump of improvement.
Background technique
The wearing and tearing of water pump vane are relevant with factors such as the chemical composition in the composition of abrasive material, granularity, concentration, shape, striking velocity, angle of attack, water body, character, temperature and humidity.And the nonuniformity of impeller internal media flow accelerates wearing and tearing.
The measure of wearing and tearing as preventing water pump vane: be one, reduce the impurity content entered in the water body of water pump, must must carry out Overall Reconstruction to water pump operation environment for this reason, in general realize more difficult; Two, be manage to make concentrated wear be tending towards uniform wear, this just needs the wear resistance improving water pump vane.Certainly high hardness and the good material of wear resistance can be adopted to carry out casting impeller if improve the wear resistance of impeller, but this bring difficulty not only can to impeller manufacturing process, and economically also more unreasonable, increase considerably production and the user cost of impeller.Our company, when designing new water pump wheel, adopts multiple-blade combination, each joint connects two blades, as a combination, when a blade from becoming worn, centrifugal force shakiness can not be there is rapidly, rotate situation about getting stuck, the continuation that can maintain a period of time runs.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, claimant, through repeatedly putting into practice improvement, devises a kind of two points of blade impeller of pump of improvement, by designing two groups of blade work in combination, when preventing a blade impaired, can also continue to run a period of time.
Technological scheme: in order to realize foregoing invention object, the technological scheme that the utility model adopts is: a kind of two points of blade impeller of pump of improvement, comprise upper cover plate, lower cover plate and be arranged on the impeller assembly in the middle of upper cover plate and lower cover plate.Described impeller assembly is three joint compositions, and one end of described joint arranges lobus sinister sheet, and the other end of joint arranges lobus dexter sheet.
Described lobus sinister sheet and lobus dexter sheet are for bending towards unidirectional circular arc vane.
Further, the further technological scheme that the utility model adopts is: the inwall of described joint arranges screens and gives prominence to, and the transmission shaft for being connected and fixed impeller is given prominence in three screens.
Beneficial effect: compared with prior art, its beneficial effect is the utility model:
The utility model by by designing two groups of blade work in combination, when preventing a blade impaired, can also continue to run a period of time, prevents impeller can not be out of service suddenly when running impaired, and to unloading, maintenance and replacing reserve time enough.
Accompanying drawing explanation
Fig. 1 is the structural representation of two points of blade impeller of pump of a kind of improvement of the utility model.
Embodiment
Below by a most preferred embodiment, the technical program is described in detail, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of two points of blade impeller of pump of improvement, comprise upper cover plate 1, lower cover plate 5 and are arranged on upper cover plate 1 impeller assembly middle with lower cover plate 5.Described impeller assembly is that three joints 2 form, and one end of described joint 2 arranges lobus sinister sheet 3, and the other end of joint 2 arranges lobus dexter sheet 4.
Described lobus sinister sheet 3 and lobus dexter sheet 4 are for bending towards unidirectional circular arc vane.
The inwall of described joint 2 arranges screens outstanding 6.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
