[0003] However, the inducer in the prior art generally adopts an integrated structure. Once a part is damaged, the entire inducer needs to be replaced, which increases the maintenance cost. Due to the complex structure, the integrated mold needs to make a complicated mold, which increases the manufacturing cost.

Embodiment Construction
[0053] like Figure 1 to Figure 5 As shown, it is a high-speed inducer suitable for a low temperature environment according to the present invention, including a connecting part 1 and at least two inducer monomers 2, the inducer monomer 2 includes an axle 3 and blades 4, and at least two blades 4 are uniform It is arranged on the outer circumferential side of the wheel shaft 3, and the blades 4 on two adjacent induction wheel units 2 are connected by a first fixing mechanism. The first fixing mechanism includes an arc-shaped connecting bar 9, which is located on the blade On the opposite side of the contact surface of 4, the fixed connection between two adjacent blades 4 is realized through the arc-shaped connecting strip 9 on both sides of the contact surface through the screw, and the design of the arc-shaped connecting strip 9 and the screw can improve As for the connection strength between two adjacent blades 4, since the blades 4 are relatively thin, direct screw connecti...

The invention discloses a high-speed inducer suitable for a low-temperature environment and a manufacturing method thereof. The high-speed inducer comprises a connecting part and at least two inducerbodies, wherein the inducer bodies comprise wheel shafts and blades, the blades on two adjacent inducer bodies are connected through a first fixing mechanism, the outer side surfaces of the two adjacent wheel shafts are connected through a second fixing mechanism, the two adjacent wheel shafts are connected through a first clamping mechanism, and the wheel shafts are connected with the connectingpart through a second clamping mechanism. The manufacturing method comprises the following steps: wheel shaft processing, blade processing, connecting part processing and inducer splicing and fixing.Through the design of the inducer bodies and the connecting part, the length of the high-speed inducer can be selected according to actual installation and use requirements, the inducer bodies which are damaged locally can be replaced, the whole inducer does not need to be replaced, and the maintenance cost is greatly reduced.
Description
technical field [0001] The invention relates to a high-speed inducer suitable for a low-temperature environment and a manufacturing method thereof. Background technique [0002] The high-speed development trend of the liquid rocket engine centrifugal pump and the delivery of low-temperature medium make the inlet of the centrifugal pump particularly prone to cavitation. Installing an inducer is the most effective way to improve its cavitation. At the same time, it can weaken the system vibration, noise and cavitation damage caused by the pump due to cavitation. [0003] However, the inducer in the prior art generally adopts a one-piece structure. Once a part is damaged, the entire inducer needs to be replaced, which increases the maintenance cost. Due to the complex structure of the one-piece mold, complex molds need to be made, which increases the manufacturing cost. Contents of the invention [0004] The purpose of the present invention is to provide a technical proposal...
