Description
Technical field
The present invention relates to water pump technology, and in particular to a kind of to produce different lift impellers using existing impeller mold
Production technology.
Background technology
Pump product has been carried out standardizing unlike motor product, to power of motor, so the power gear number of motor is
Fixed.And the performance parameter of pump product is ever-changing, even the required performance of client is also in this way, a serial production
Product, it can not meet to require sometimes.In type selecting, often occur a kind of lift of original shape pump lower than the lift of customer demand 2 to
5m, such as pump from a big specification, the external diameter of impeller will cut many, the efficiency of pump is declined more, the cost of another pump also carries
Height, client are also reluctant to receive.The production process of present pump is first to carry out the Preliminary design of pump, according to manufacturing and designing water pump sample,
If the water pump sample parameters of verification are undesirable, need to re-start design and manufacture, this process cost is high, production week
Phase is grown.
The content of the invention
The technical problems to be solved by the invention, which are to provide, is easy to a kind of utilize for adjusting pump performance parameter to have impeller
Mould produces the production technology of different lift impellers.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of production technology that different lift impellers are produced using existing impeller mold, its technical process are included：
(1) according to impeller mold blade profile, loose piece is made, it is desirable to which loose piece has certain thickness, can be bonded on the inside of loose piece
To impeller mold front side of vane exit；
(2) by the connected loose piece of the marginal position of each blade of impeller mold, new impeller core mould is obtained；
(3) new impeller mould is put into molding sand and carries out coremaking, after the completion of coremaking, take out new impeller core；
(4) molten iron casting shaping can be carried out after core is put into the die cavity for completing moulding, obtains impeller blank；
(5) impeller blank is subjected to turnery processing, Milling Process finally is carried out to vacuum side of blade outlet ends, according to itself
Demand, mill out different blade outlet angles.
All may be used it is preferred that the loose piece material is wooden or plastics.
The beneficial effects of the invention are as follows：
One set of die must be made using conventional method, fabrication cycle length, resulting cost and costly.And use this
Inventive method, need only make several wooden loose pieces, and the impeller cast out can obtain different outlet blade angles, impeller by milling
Parameter need not redesign manufacture mould when undesirable, and fabrication cycle is short, and production cost and expense are also corresponding low.
The present invention relates to technical scheme, can easily make impeller outlet side thickening, and then can pass through method for milling
To increase outlet blade angle, it is easy to adjust the lift of pump.Such a innovative approach, not only cost is low, fabrication cycle is short, and can grasp
The property made is strong, and practicality is also very strong.

Conjunction is specifically illustrating, and the present invention is expanded on further.
A kind of production technology that different lift impellers are produced using existing impeller mold, its technical process are included：
(1) as shown in figure 1, selecting the specifications and models of pump as requested, according to pump type specifications design impeller, and leaf is selected
Wheel model 1, the centre position of impeller mould 1 are provided with false boss 4, according to the profile of impeller mould blade 3, make loose piece 2, it is desirable to which loose piece 2 has
Certain thickness, the inner side of loose piece 2 can be fitted at the working face outlet edge of impeller mold blade 3；The material of loose piece 2 is wooden
Or plastics.
(2) by the connected loose piece 2 of the marginal position of each impeller mold blade 3, new impeller mould 1 is obtained；
(3) new impeller mold 1 is put into molding sand and carries out coremaking, after the completion of coremaking, take out core；
(4) moulding by casting can be carried out after core is put into the die cavity for completing moulding, obtains impeller hair as shown in Figure 2
Base 11；
(5) impeller blank 11 is subjected to turnery processing, processing axis hole 14 etc., the inner side of milling blade 12 as shown in Figure 2, removed
Part 13 is milled, the increase of impeller outlet angle, the pump lift of manufacture increases, according to itself or customer demand, the different leaf of milling
The piece angle of outlet, it is not necessary to redesign manufacture mould, improve production efficiency.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
