Same one.titanium stirrer8‑15 years under standard maintenance conditions, Failure to maintain properly for 3‑5 years is prone to downtime.This article takes root in Baoji China Titanium Valley and has been combined for many yearsTitanium non-standard equipmentservice experience, Sort out the practical operation points of maintenance in six stages according to the chronological order, Cover the arrival of unpacking, installation and commissioning, daily point inspection, monthly checking and maintenance, Annual overhaul and scrap judgment process, help industry, medicine, Hydrometallurgical industry extensiontitanium stirrerUse cycle to reduce risk of unplanned shutdown.

Stage 1: unpacking inspection, completed on the day of arrival Unpacking inspection shall be carried out as soon as the equipment arrives, focusing on five items.Observe whether the blades are deformed, the stirring shaft is not bent, and there is no obvious scratch on the surface;Verification of material grades using portable spectrometers, Confirm TA2 agreed with the contract, N6 and other materials remain consistentField measurement of blade diameter, shaft diameter, shaft length, and machining drawings for comparison;Check the appearance of all welds one by one, and there shall be no porosity, crack and incomplete penetration defect;Check all accessories such as bolts, flanges and mechanical seals.If any abnormality is found, the photos shall be kept as soon as possible, and the supplier shall be contacted for handling, so as to avoid exposing quality problems after installation.

Stage 2: Installation and commissioning, completed in the first week of arrival Control three key indicators during installation and commissioning.The verticality deviation of stirring shaft shall be controlled within 0.5%, so as to prevent shaking during operation.The concentricity deviation between stirring shaft and kettle mouth shall not be greater than 2 mm;After assembly, do no-load test run for 30 minutes, monitor operation sound, detect vibration and temperature data.The problem exposed in the debugging stage has the lowest cost to deal with, and it will consume a lot of manpower and time to rework and disassemble after formal use.

Stage 3: Daily spot check, performed daily by each shift The operator carries out five spot checks per shift.Listen to abnormal running noise of bearings and gearbox;Use hand feeling or vibration instrument to detect vibration. If the vibration value exceeds 5mm/s, stop the machine for investigation.Observe the leakage state of shaft seal, mechanical seal allows trace leakage, packing seal can appear a small amount of leakage;Check the motor running current, control in the no-load current plus or minus ten percent interval;Monitor bearing temperature not higher than 70℃, motor operating temperature not higher than 80℃.Daily spot check is the most effective way to identify early hidden dangers in advance.

Stage 4: Monthly maintenance, regular monthly Carry out maintenance operations once a month and implement five tasks.Retighten all fasteners such as blade connecting bolts;Add grease to bearings according to equipment instructions, and replace lubricating oil for gearbox as required;Clean up the crystallization of materials at the shaft seal position and scale on the inner wall of the kettle;Ultrasonic thickness measurement was used to record the wall thickness variation of shaft and blade.Complete monthly maintenance records and keep equipment operation files.

Stage 5: Annual overhaul, annual shutdown for deep overhaul Annual overhaultitanium stirrerThe key link of service cycle, using the device shutdown window period to disassemble the equipment full inspection.Check the wear, deformation and corrosion of blades, and replace them in time when they reach the loss threshold;Inspect the straightness, surface corrosion and wear of the mixing shaft;Even if the appearance is intact, it is recommended to replace the mechanical seal moving ring and static ring components;Check bearing clearance, clearance exceeds 0.2 mm bearings should be replaced;Synchronous completion of motor maintenance and insulation performance testing.

Stage VI: Criteria for scrapping, disposal at the end of life Any of the following conditions occur, evaluable equipment enters retirement phase, Blade wear reduces diameter by up to 10 percent., The mixing efficiency decreased obviouslyThe corrosion loss of stirring shaft reaches 20% of shaft diameter, and the structural strength is insufficient;The bending deformation of stirring shaft exceeds 0.5 per thousand, and the running vibration continues to exceed the standard;The equipment has been in operation for fifteen years. Even if the appearance is intact, it is recommended to evaluate and update it.Titanium material has recycling value, it is not recommended to directly waste, you can contact the original supplier for recycling disposal.

Overall maintenance rhythm sorting: unpacking inspection shall be carried out on the day of arrival;The first week to complete the installation and debugging;Carry out daily inspection in each shift;Monthly maintenance;Annual overhaul;Life evaluations are performed every five years to determine whether to continue service or update equipment.

The actual operation and maintenance process needs to avoid three common mistakes, Do not idle for long periods, Dry grinding of shaft seal due to idling, Accelerated seal damageIt is forbidden to knock the blade directly with hard objects. The hardness of titanium is low, and knocking will produce pits and stress concentration.Avoid direct contact with dissimilar metals such as copper and carbon steeltitanium stirrerParts, to prevent galvanic corrosion.

Frequently Asked Questions

titanium stirrerHow long can it be used normally? TA2 under standard maintenance conditionstitanium stirrerService life 8‑15 years, TA10 material up to 15‑20 years;Equipment that lacks maintenance requires extensive repairs after 3 - 5 years.

How to deal with the mixer leakage? Distinguish whether the leakage source belongs to the shaft seal or the kettle body.Shaft seal leakage can be tightened gland or directly replace the seal assembly;The leakage of the kettle body needs to be stopped for repair welding or component replacement.

How often is bearing replacement recommended? 3‑5 years under normal operating conditions, check the clearance every year during overhaul, and replace it immediately if the index exceeds the standard.

titanium stirrerHow to clean? Dilute nitric acid with a concentration of no more than 5% can be used to clean the scale, and then washed with clean water;It is forbidden to use hydrofluoric acid and hydrochloric acid for cleaning operation.

scraptitanium stirrerHow do we deal with it? Titanium is a recyclable metal, Contact Titanium Supplier Recycling, Recycling prices are typically 30%‑50% of the new raw material price.
