22、 and specificationQuantity(set)Internal diametermmDesilting calibermmCone angleOne-stage500x4250065-80202 Preparation before work2.1 Check, before starting, whether the abrasion of feed pipe, bed charge pipe, overflow pipe and conical drum is severe, whether the pipe has water or material leakage ph
23、enomenon, whether the overflow tank and underflow tank have sundries, and whether the control valve is flexible and tight.2.2 Valves may be completely opened (such as operating swirler) or completely closed (such as standby swirler), but shall not be in half opening state (i.e. valves shall not be u
24、sed to control flow).3 Normal operation3.1 In normal operation of equipment, frequently check the stability of pressure gauge, flow size of overflow and underflow, discharge state, and regularly detect the overflow and underflow concentration and fineness.3.2 The feeding pressure shall be stabilized
25、 above the pressure required for production (feed pressure 0.10.12Mpa) and shall be free from large fluctuation generation.3.3 Frequently check whether the overflow and underflow discharges of all the operating swirlers are smooth.3.4 Frequently observe the swirler underflow discharge state, and per
26、iodically detect the underflow concentration and fineness. Timely adjust underflow concentration fluctuation or underflow from fine particle uniformity. In normal working condition of the swirler, the bed charge discharge shall be umbrella shaped. If the underflow concentration is too large, the und
27、erflow will be discharged columnar or blocky.3.5 Regularly detect the overflow concentration and fineness. The increase of overflow concentration or overflow from coarse particle may be related to the increase of feed concentration and to the blocking of underflow opening. Adjustment: if any overflo
28、w from coarse particle, first detect whether the underflow opening is blocked, and then detect the feed concentration, and adjust according to specific conditions.3.6 When the equipment is in smooth operation at constant pressure, check the leakage of the connecting point and take remedial measures
29、if necessary.4. Handling for special circumstancesIf the feeding pressure drops, the following check needs to be conducted:4.1 If the pressure fluctuation is caused by the drop of pump tank liquid level, the adjustment may be conducted through increasing the liquid level or shutting down one or two
30、swirlers or reducing the pumping speed.4.2 If the pressure fluctuation is caused by pump blocking or abrasion, the pump needs to be overhauled.5 Stop operation5.1 For stop, the ore pulp sump shall be emptied timely in case of blocking accident caused by precipitate and too high concentration in star
