The mining flotation machine is also one of the mineral processing equipment, but compared with other mineral processing methods, the application method of the mountain flotation flotation method is more extensive, because it can be applied to almost all the ore flotation operations, then the species How is the flotation machine checked after long-term use?
The following is a detailed introduction to you in six parts:
1. Check the outer diameter of the water inlet of the water wheel one by one, and check the verticality of the balance plate: place the dial gauge contact on the end surface of the balance plate, turn the shaft one turn, and the difference between the maximum and minimum values ​​of the dial indicator. That is, it is not perpendicular.
2. The balance plate is not vertical. During the operation, the balance plate will be grounded. Checking methods such as radius: After adjusting the impeller pitch and each gap, fix the assembled rotor on the lathe or mount the bearing on the rotor shaft. Then put it on the v-shaped iron , use the dial gauge to measure the view, touch the dial gauge contact to the test piece, and rotate the shaft one turn. The difference between the large reading of the kilometer needle and the minimum reading is the eccentricity.
3. To ensure the healthy and orderly work of the mining flotation machine is the prerequisite for improving the efficiency of mineral processing.
4. Therefore, it is necessary to inspect the bushing, the impeller and the balance plate one by one. Under normal circumstances, the eccentricity of the bushing and the impeller does not exceed -01 mm. The eccentricity of the flat street plate does not exceed 0.5 mm.
5. If the eccentricity and verticality are not acceptable, replace and trim. For the impeller and the cover of the consumables we need to prepare in advance and find the replacement even if it is damaged.
6. The final inspection should be divided into overhaul, medium repair and minor repair. Check the eccentricity and the non-perpendicularity of the balance disc. If the eccentricity is too large, the rotor of the flotation machine will vibrate during operation, and the pump shaft will bend and water. The outer diameter of the wheel inlet is offset and the impeller is ground.
