Abstract
The utility model discloses a kind of improved water pump, including water inlet line, the pump housing, outlet conduit, the water inlet line is connected to the side of the pump housing, and the other side of the pump housing is additionally provided with motor, outlet conduit is connected on the upside of the pump housing；The output shaft of the motor runs through the pump housing, and output shaft is connected with impeller and inducer；The impeller is set to the inner cavity of the pump housing, and the inducer is set on the inside of water inlet line；The water inlet line is tapered into close to pump housing end side water inlet；Using above-mentioned technical proposal, since the inducer is set on the inside of water inlet line；The water inlet line is tapered into close to pump housing end side water inlet；The impeller is bilobed wheel so that the pump housing preferably prevents cavitation problem, reduces the failure of centrifugal pump, improves working efficiency.
Description
Technical field
The utility model is related to a kind of liquid supercharging equipment, more particularly to a kind of improved water pump.
Background technology
With the development of society, the cavitation problem of water pump has become the problem of people increasingly pay attention to, currently, research is anti-
The cavitation erosion method of sealing pump, has become a new research topic；
But in the prior art, since water pump is all traditional structure, water is due to the strong gas when suction pressure reduces
Change, pre- cavitation-preventive, centrifugal pump cannot be easy failure well, cause working efficiency not high.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of pre- cavitation-preventive, the modified water of raising working efficiency
Pump.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
A kind of improved water pump, including water inlet line, the pump housing, outlet conduit, the water inlet line are connected to the one of the pump housing
The other side of side, the pump housing is additionally provided with motor, and outlet conduit is connected on the upside of the pump housing；
The output shaft of the motor runs through the pump housing, and output shaft is connected with impeller and inducer；The impeller is set to the pump housing
Inner cavity, the inducer is set on the inside of water inlet line；
The water inlet line is tapered into close to pump housing end side water inlet.
Preferably, the impeller is bilobed wheel.
Preferably, it is provided with bushing on the inside of the pump housing.
Preferably, the inducer is arranged close to water inlet.
Using above-mentioned technical proposal, since the inducer is set on the inside of water inlet line；The water inlet line is close to pump
Body end side water inlet tapers into；The impeller is bilobed wheel so that the pump housing preferably prevents cavitation problem, reduces centrifugal pump
Failure improves working efficiency.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
In figure, 1- water inlet lines, the 2- pump housings, 3- motors, 4- outlet conduits, 5- impellers, 6- inducers.
Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figure 1, a kind of improved water pump, including water inlet line 1, the pump housing 2, outlet conduit 4, water inlet line 1 connect
In the side of the pump housing 2, the other side of the pump housing 2 is additionally provided with motor 3, and the upside of the pump housing 2 is connected with outlet conduit 4；
The output shaft of motor 3 runs through the pump housing 2, and output shaft is connected with impeller 5 and inducer 6；Impeller 5 is set to the pump housing 2
Inner cavity, inducer 6 are set to 1 inside of water inlet line；
Water inlet line 1 is tapered into close to pump housing end side water inlet.
In addition, impeller 5 is bilobed wheel, improves the flow of centrifugal pump, improves working efficiency.
Further, 2 inside of the pump housing is provided with bushing, preferably prevents the pump housing from being cavitated.
In addition, the inducer 6 is arranged close to water inlet, increases the hydraulic pressure into the pump housing 2, better pre- gas-tight in advance
Erosion problem.
The embodiment of the utility model is explained in detail above in association with attached drawing, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the scope of protection of the utility model.
