Abstract
The utility model discloses a kind of water pump gland ring, including sealing ring body, the inner side of described sealing ring body is provided with gap direction and the angle [0 °, 40 °] of impeller axis at labyrinth type groove, and sealing ring leakage jet exit.The inner side of described sealing ring body is provided with single labyrinth type groove.The inner side of described sealing ring body is provided with double labyrinth type groove.Compared with existing impeller seals annular type, impeller ring provided by the utility model, when water pump operation, owing to there is not the vortex that leakage jet causes, and can also increase main flow energy, therefore can improve pump efficiency.
Description
Technical field
This utility model relates to water pump field, particularly relates to a kind of water pump gland ring.
Background technology
In current water pump, the commonly used clearance seal of impeller inlet sealing ring, its gap water leakage flow path direction and impeller
The main water (flow) direction of import is vertical.The leakage flow velocity that the impeller inlet seal clearance that is in operation produces is higher, to impeller inlet main flow
Produce interference, cause vortex, and then add drag losses, affect pump efficiency.
Utility model content
The purpose of this utility model is contemplated to solve the problems referred to above, it is provided that a kind of water pump gland ring, by original and main
Flow vertical impeller seals clearance leakage water export direction and be adjusted to close with impeller eye main flow direction, make leakage jet pair
Part main flow liquid produces useful rolling action, adds main flow energy, improves pump efficiency.
To achieve these goals, this utility model adopts the following technical scheme that
A kind of water pump gland ring, including sealing ring body, the inner side of described sealing ring body is provided with labyrinth type groove, and close
Gap direction and the angle [0 °, 40 °] of impeller axis at seal ring leakage jet exit.
The inner side of described sealing ring body is provided with single labyrinth type groove.
The inner side of described sealing ring body is provided with double labyrinth type groove.The beneficial effects of the utility model are:
Compared with existing impeller seals annular type, impeller ring provided by the utility model when water pump operation,
Owing to there is not the vortex that leakage jet causes, and main flow energy can also be increased, therefore can improve pump efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of embodiment one；
Fig. 2 is the schematic diagram of embodiment two；
Fig. 3 is the schematic diagram of embodiment three；
Wherein, 1 housing, 2 sealing rings, 3 impellers, q leaks jet direction, the main water (flow) direction of Q, and q+ leakage jet carries part
Main flow direction.
Detailed description of the invention:
With embodiment, this utility model is described further below in conjunction with the accompanying drawings:
Embodiment one
As it is shown in figure 1, a kind of water pump gland ring, including housing 1, sealing ring 2, impeller 3, described sealing ring 2 is arranged on shell

Angle, preferred angle is less than 40 °.
Embodiment two
As in figure 2 it is shown, a kind of water pump gland ring, including housing 1, sealing ring 2, impeller 3, described sealing ring 2 is arranged on shell
On body 1, form fit clearance, described sealing ring 2 and described impeller 3 gap leakage current Way out q and main water (flow) direction with impeller 3
Q is the most close.
Described sealing ring 2 is labyrinth pattern with described impeller 3 fit structure, uses double labyrinths pattern, has two grooves, on
The groove in face can be arbitrary shape, and the surface of nethermost groove is acute angle 40 ° with the angle of sealing ring body bottom surface,
Gap leakage jet direction q water (flow) direction Q main with entrance is close.
Embodiment three
As it is shown on figure 3, a kind of water pump gland ring, including housing 1, sealing ring 2, impeller 3, described sealing ring 2 is arranged on shell
On body 1, form fit clearance, described sealing ring 2 and described impeller 3 gap leakage current Way out q and main water (flow) direction with impeller 3
Q is the most close.Sealing ring 2 and described impeller 3 fit structure are single labyrinth pattern, and at the bottom of the surface of groove and sealing ring body
The angle in face is 0 °.
Although detailed description of the invention of the present utility model is described by the above-mentioned accompanying drawing that combines, but not new to this practicality
The restriction of type protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, ability
Field technique personnel need not to pay various amendments or deformation that creative work can make still at protection model of the present utility model
Within enclosing.
