Description
Technical field
The utility model relates to high-pressure pump apparatus field more particularly to a kind of impellers for high-pressure pump.
Background technique
In daily life, it is often necessary to take the clear water in well, be all under normal circumstances connected with the mains with down-hole water pump it is logical
Piping is connected to user's interior room auto-watering, and the water pump of underground has a certain altitude apart from ground, and the user that pipeline is communicated to
It may be Stall, it may be possible to ten buildings, Shi Wulou, and in this process, the height that water rises in pipeline needs hydraulic pressure to support, and
Generate hydraulic pressure is exactly water pump nothing but, so, the size that a water pump generates hydraulic pressure determines the height that can convey water, for
For high-rise user, supply water just at a very severe problem, most users are all utilized in attic and build one
A water tank water storage mode gives supply water, and high-level user generally uses booster station, using more water pump parallel connections, according in pipe network
Pressure change starts or stops water pump to adjust the pressure in pipe network, because ductwork pressure sometimes it is unstable due to cause water pump to fetch water
Power is short of power, and not only affects rate of fetching water, but also compromise water pump, meanwhile, using booster station fetch water with specific
Rate of fetching water is fast, separate unit water pump that hydraulic pressure is sufficient is compared, the equipment of purchase not only fetch water but also compared with power consumption by somewhat expensive.
Water pump in the prior art mostly uses greatly immersible pump, deep well pump, is made of pump case, impeller, pump shaft, pump bracket etc., rises
The impeller rotated after dynamic drives the water high speed rotation in pump, and water makees centrifugal movement, throws away and be pressed into outlet pipe outward, and water is got rid of
After out, the pressure near impeller reduces, and a low-pressure area is just formed near shaft, and pressure here is more much lower than atmospheric pressure,
The water of outside just under atmospheric pressure, is washed bottom valve open and is entered in pump from water inlet pipe, and the water rushed in is revolved with impeller high speed
It is thrown out of again in turning, and is pressed into outlet pipe, impeller continuous high speed rotation under engine drive, water is just continuously from lower
It is pumped to eminence；At work, the pressure that impeller is born is very big for this water pump, impeller can many times occur splits etc. to ask
Topic.

Embodiment
As shown in FIG. 1 to 3, a kind of impeller for high-pressure pump described in the present embodiment, the impeller include: upper wheel cap
10, lower wheel cap 20；
Thick blade 30 between the upper wheel cap 10 and lower wheel cap 20 is set；
Inlet opening 40 among the upper wheel cap 10 is set；
Rotation axis 50 among the lower wheel cap 20 is set, and the rotation axis 50 is perpendicular to lower wheel cap 20, rotation axis 50
One end connects lower wheel cap 20, and the other end extends into inlet opening 40 and horizontal concordant with inlet opening 40；
Multiple broad-leaved pieces 60 in inlet opening 40 are set, and 60 wider portion of broad-leaved piece connects inlet opening 40, relatively narrow
Part is connect with rotation axis 50；
The upper wheel cap 10, lower wheel cap 20, thick blade 30, inlet opening 40, rotation axis 50, broad-leaved piece 60 are integrally formed knot
Structure.
When operation, driving device impeller is rotated clockwise, and water is pressed to leaf by inlet opening 50 by the rotation of broad-leaved piece 60
Wheel is internal, rotates through thick blade 30 water throwing away impeller.
The upper wheel cap 10, lower wheel cap 20, thick blade 30, inlet opening 40, rotation axis 50, broad-leaved piece 60 of the utility model are one
Forming structure, compared to general split type impeller, the pressure that the utility model is able to bear is bigger, is less prone to blade folding
The bad situation of breakdown is more suitable for the high-revolving high-pressure pump of high power.
As shown in Figure 3 or Figure 4, the thick blade 30 includes: thick blade 30 close to the Drainage Section of rotation axis 50 31, thick blade
30 middle sections push away water section 32, and thick water dumping section 33 of the blade 30 far from rotation axis 50.
As shown in Figure 3 or Figure 4, the Drainage Section 31, push away water section 32, the thickness of water dumping section 33 is sequentially increased.
When thick blade 30 throws away water from impeller, drainage is played in Drainage Section 31, and receiving pressure is smaller, pushes away water section
32 play the role of pushing away water, and it is larger to bear pressure, and the effect of water dumping section 33 is to throw away water, and the pressure of receiving is greater than Drainage Section
31, push away water section 32, the Drainage Section 31 of the thick blade 30 of the utility model, push away water section 32, the thickness of water dumping section 33 is sequentially increased, one
Aspect can reinforce the bearing capacity of thick blade 30, on the one hand mitigate impeller weight, reduce power loss.
The Drainage Section 31, push away water section 32, the radian of water dumping section 33 is sequentially increased.According to Drainage Section 31, pushes away water section 32, gets rid of
The pressure that water section 33 is born is sequentially increased, Drainage Section 31, push away water section 32, the radian of water dumping section 33 is also sequentially increased, increase arc
Degree can reduce water to the active force in thick 30 vertical direction of blade, to reduce high pressure to thick 30 bring of blade damage.
As shown in figure 3, the quantity of the thickness blade 30 is six.The quantity of thick blade 30 is excessively sparse, to high-pressure hydraulic pump
Flow velocity and the pressure raising of interior water be not it is obvious that if the quantity of blade 30 excessively can intensively reduce the reservoir storage in impeller,
Even if water flow velocity is fast, the flow of water pump in the unit time can not be also improved, so setting six most for the quantity of thick blade 30
It is good.
As shown in Figure 1,60 general shape of broad-leaved piece is isosceles trapezoid.What broad-leaved piece 60 primarily served be by hydraulic pressure to
Impeller internal, blade area is bigger, and the water that can be pressed into is bigger, produces between blade if having more overlapping region between blade
It is raw to influence, it is unfavorable for setting isosceles-trapezium-shaped for hydraulic pressure such as impeller, is relatively narrow upper of isosceles trapezoid close to 50 side of rotation axis
Side, be in addition on one side it is wider following, can effectively increase the effective area of blade, to increase the water of indentation, simultaneously
Avoid blade is excessive from leading to the more influence indentation water in overlapping region.
As shown in Fig. 2, the broad-leaved piece 60 is 45 degree relative to the inclination angle of rotation axis 50.Angle is at 45 degree, broad-leaved
Piece 60 can reach balance entering hydraulic pressure when rotated between the pressure of impeller and water, existing biggish pressure, and not shadow
Ring the water being pressed into the unit time.
The rotation axis 50 is solid construction, and the one end in inlet opening 40 of rotation axis 50 is provided with driving device (in figure
Be not shown) connection rotation hole 51.Solid construction is capable of increasing the rigidity of rotation axis 50, not easily damaged.
As shown in figure 5, the shape of the rotation hole 51 is I-shaped.I-shaped rotation hole can be connect not with driving device
It can skid, and not easily damaged in special circumstances in emergency braking etc..
It should be noted that, in this document, such as first and second or the like relational terms are used merely to one if it exists
A entity or operation with another entity or operate distinguish, without necessarily requiring or implying these entities or operation it
Between there are any actual relationship or orders.Moreover, the terms "include", "comprise" or its any other variant are intended to
