Description

Technical Field

[0001] This application relates to the field of impeller wear resistance testing technology, specifically to a slurry pump impeller for wear resistance testing using a multi-material combination. Background Technology

[0002] Slurry pumps, as key equipment for conveying high-concentration solid-liquid mixtures, are widely used in mining, metallurgy, dredging, and other fields. The impeller, as its core component, is subjected to the impact, cutting, and corrosion of high-speed particles over long periods, leading to severe wear. Since slurry pump impellers operate under high-wear conditions for extended periods, the choice of materials directly affects their lifespan and efficiency.

[0003] In existing technologies, impellers are usually made of a single material. Although their wear resistance is tested through laboratory simulation or actual operation, it is time-consuming and costly to replace impellers made of different materials multiple times during testing. Furthermore, the fluctuation of parameters such as flow rate and particle concentration in different batches of tests leads to poor data comparability, which in turn affects the accuracy of test results. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a slurry pump impeller for multi-material combination wear resistance testing, which can simultaneously test blades made of multiple materials, has low testing cost, and high testing accuracy. The technical solution adopted is as follows:

[0005] The impeller of the slurry pump for wear resistance testing of multiple materials is installed in the slurry pump body and includes a hub and several sets of test blades on the hub. Each set of test blades is made of a different test material. The test blades are arranged along the circumferential direction of the hub and each set of test blades is symmetrically arranged.

[0006] Preferably, the wheel hub is made of titanium alloy. This significantly reduces rotational inertia, decreases starting energy consumption and vibration load, extends service life, and reduces the frequency of replacement.

[0007] Preferably, the blade to be tested is detachably connected to the hub via a connecting component, so that the blade to be tested can be disassembled.

[0008] Preferably, the wheel hub is also provided with a counterweight structure for adjusting the wheel hub balance. This ensures smooth operation, reduces vibration and wear, and extends service life.

[0009] Preferably, the blades to be tested are evenly distributed along the circumferential direction of the hub.

[0010] Compared with the prior art, the beneficial effects of this application are as follows:

[0011] This application symmetrically arranges test blades of different materials on the hub along the circumferential direction, thereby enabling simultaneous testing of test blades of multiple materials, significantly improving material screening efficiency and reducing testing costs. Furthermore, the test blades operate under the same flow rate, particle concentration, and rotational speed, undergoing wear simultaneously, resulting in higher testing accuracy.

[0019] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] See Figures 1 to 3 To further elaborate on this application:

[0021] Combination Figure 1 and Figure 2 The impeller of the slurry pump for wear resistance testing of multi-material combination is installed in the slurry pump body 100. The impeller 200 includes a hub 10 and several sets of test blades 40 disposed on the hub 10. In this embodiment, there are 6 test blades 40, which are divided into three groups. Each group of test blades 40 consists of two blades. The number of groups of test blades 40 is not limited.

[0022] For ease of explanation, the blades 40 to be tested are divided into four groups in a clockwise direction: a first blade 41, a second blade 42, a third blade 43, a fourth blade 44, a fifth blade 45, and a sixth blade 46. The first blade 41 and the fourth blade 44 form the first group, the second blade 42 and the fifth blade 45 form the second group, and the third blade 43 and the sixth blade 46 form the third group. The number of blades 40 to be tested can be set as needed; each group can contain one, three, or four blades, etc., and the quantity can be adjusted accordingly.

[0023] Each group of test blades 40 is made of a different testing material; that is, each group of test blades 40 is made of a different material. The test blades 40 are arranged circumferentially along the hub 10, and each group of test blades 40 is symmetrically arranged, with the test blades 40 evenly distributed along the circumferential direction of the hub 10. In this embodiment, the test blades 40 are made of three different materials: the first group of test blades 40 is made of high-chromium cast iron, the second group of test blades 40 is made of tungsten carbide composite material, and the third group of test blades 40 is made of duplex stainless steel. The test materials and quantities can be set according to actual needs.

[0024] This application symmetrically arranges test blades 40 of different materials on the hub 10 in the circumferential direction, thereby enabling simultaneous testing of test blades 40 of multiple materials, significantly improving material screening efficiency and reducing testing costs. At the same time, the test blades 40 operate under the same flow rate, particle concentration, and rotation speed, and undergo wear simultaneously, resulting in higher testing accuracy.

[0025] In this embodiment, the wheel hub 10 is made of titanium alloy. Carbon alloy has unique advantages such as lightweight, high strength, corrosion resistance, and high temperature resistance, which can significantly reduce rotational inertia, reduce starting energy consumption and vibration load, improve service life, and reduce replacement frequency.

[0026] Combination Figure 3 In some embodiments, the blade to be tested 40 is detachably connected to the hub 10 via a connecting component 20, so that the blade to be tested 40 can be disassembled. The connecting component 20 can be a rivet, which, by riveting, mounts the blade to be tested 40 onto the hub 10, ensuring connection strength and fatigue resistance.

[0027] Combination Figure 3 In some embodiments, the wheel hub 10 is further provided with a counterweight structure 30 for adjusting the balance of the wheel hub 10. The counterweight structure 50 ensures smooth operation, reduces vibration and wear, and improves service life.

[0028] The counterweight structure 30 includes a counterweight block. By setting the counterweight block on the hub 10, the dynamic balance of the impeller 200 can be adjusted. The surface of the hub 10 may have a pre-reserved counterweight groove, and the counterweight block is set in the counterweight groove.
