Detailed Description
It is specifically noted that, in the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise; the meaning of "several" is at least one. In the embodiment of the present invention, all the directional indicators (such as upper, lower, left, right, front, rear \8230;) are used only to explain the relative positional relationship between the components in a specific posture, the motion situation, etc., and if the specific posture is changed, the directional indicator is changed accordingly.
The technical solution of the present invention is further described below by way of examples:
the utility model provides a bimetal composite turbine, as shown in the combined drawings of 1 to 4, the turbine includes: the copper alloy sleeve 2 is provided with a positioning pin 21, an inner circle portion 22 and an outer circle portion 23, the inner circle portion 22 and the outer circle portion 23 are both in a cylindrical shape, the outer circle portion 23 is provided with blades 24, the inner circle portion 22 is connected with the outer circle portion 23 through the positioning pin 21, the steel base 1 is located between the inner circle portion 22 and the outer circle portion 23, and the positioning pin 21 penetrates through the positioning hole 11.
During manufacturing, the steel base 1 can be cast, the positioning hole 11 of the steel base 1 serves as a flow channel, the steel base 1 is placed in a centrifugal casting mold, then copper alloy liquid is injected into the center of the centrifugal casting mold, under the action of centrifugal force, the copper alloy liquid fills the space reserved for the inner circle part 22 and the outer circle part 23 in the mold, the positioning pin 21 is formed in the positioning hole 11, and finally the turbine is cooled and taken out. Because of the steel base 1, the overall cost of the turbine is low. As the positioning holes 11 are arranged on the side wall of the steel base 1, the casting process can be homogenized through centrifugal force, the cooling speed is averaged, the process time is short, the temperature difference change is small, and the three-layer metal structure is successfully produced.
In use, the inner portion 22 of the copper sleeve 2 is secured to the shaft and fluid impacts against the blades 24 causing the turbine to rotate, thereby driving the shaft to rotate. Wherein:
1. because the excircle part 23 of the copper alloy sleeve 2 is arranged on the outer side of the steel base 1, the copper alloy has good wear resistance and corrosion resistance, and the formed blade 24 has long service life and is easy to process.
2. Since the inner circular section 22 of the copper alloy sleeve 2 is arranged on the inner side of the steel base 1, when the turbine needs to slide along the axial direction or rotate to slide to adjust the position, the friction force generated during sliding can be small, and the sliding assistance effect can be achieved.
