titanium stirrerIt is the core non-standard equipment of chemical anti-corrosion working conditions., When equipment operation is abnormal, Most users will contact the manufacturer directly for maintenance.In fact, most routine faults can be quickly solved through independent troubleshooting, effectively reducing maintenance expenses.Shaanxi Billion Tuoda, rooted in Baoji China Titanium Valley, deeply cultivatedTitanium non-standard equipment12 years of manufacturing combined with extensive field service experiencetitanium stirrerEighty percent of routine failures are caused by aging of basic accessories.Priority check seals, bearing, Three core parts of the motor, With standardized screening procedures, Most equipment problems can be solved efficiently.
core conclusions：titanium stirrerFaults are mainly divided into seal leakage, equipment vibration, motor overload, bearing damage, Five categories of blade anomalies, Aging of basic fittings is the main cause.Master three kinds of core components screening method, Standardized maintenance steps for five types of faults, Can quickly locate problems, Suitable for most chemicalstitanium stirrerOperation and maintenance scenarios.
First, high-frequency fault: seal leakage (accounting for 60% of the fault)
Seal leakage istitanium stirrerThe most frequent faults can be checked and repaired through a three-step standardized process.First observe the leak location, pinpoint the root cause of failure, Leakage at contact surface between moving ring and stationary ring, Mostly friction wear, Damage to sealing surfaceO-ring position leakage, high probability is aging seal ring, model specifications do not match;Seal gland leakage, usually fixed bolt loose, matching gasket damage;Double-end seal isolation fluid leakage, mostly caused by insufficient isolation fluid pressure.
Second, check the core operating parameters, The temperature of the sealed cavity exceeds 80℃, and it is necessary to immediately stop the machine for inspection., Axial vibration value more than 4.5 mm/s belongs to the warning state, At the same time, check the sealing gland with a feeler gauge, The standard compression should be kept in the range of 1-2 mm.Finally, according to the fault root cause targeted treatment, O ring aging can be directly replaced accessories;The wear of friction pair needs to replace the whole set of mechanical seals;If the pressure of isolating fluid is insufficient, it can be equipped with fluid pump and pressure gauge to stabilize the pressure.
Operation and maintenance pit avoidance, Seal leakage Do not press gland blindly, Over-extrusion can cause seal spring failure, Aggravating leakage problems, Shorten the service life of seal fittings.
II. Dangerous fault: equipment vibration is too large (accounting for 20% of faults)
The abnormal vibration of agitator belongs to high-risk early warning fault. Long-term operation with vibration is easy to cause equipment damage. It needs three-step investigation and rectification.Step 1 Distinguish vibration types, Accurate positioning problem, Horizontal vibration is too large, Most of them are impeller scaling, The blade defect leads to uneven stressAbnormal vertical vibration, bearing damage, loose equipment foundation with high probability;The axial vibration exceeds the standard, generally because the stirring shaft is bent and the equipment alignment accuracy is insufficient.
Step 2: Check the vibration value, At the equipment level, vertical, Multi-point detection in three axial directions, Vibration value ≤3.5mm/s is normal state, 3.5-4.5mm/s needs to be paid attention to, 4.5-7.1mm/s trigger warning, If it exceeds 7.1mm/s, it must be stopped immediately for maintenance.Step 3 Targeted rectification, Impeller scaling can be shut down for cleaning, Blade defect requires replacement of impeller, Bearing damage timely replacement parts, Mixing shaft bending can be straightened, repaired or replaced directly, The loose foundation needs to be reinforced and poured again.
Operation and maintenance pit avoidance, Vibration value exceeds the standard, continuous operation is strictly prohibited., Under high load vibration conditions, Major faults such as broken shaft can occur in short-term operation of equipment, causing equipment downtime losses.
Third, the working condition fault: motor overload (accounting for 10% of the fault)
Motor overload fault mostly occurs after equipment modification and condition adjustment, which can be quickly checked through three-step process.First, use clamp ammeter to detect three-phase current, Current ≤ rated current 80% is normal working condition, Overload warning is triggered when the rated current reaches 100%., More than 120% should be stopped immediately.Second, check the overload cause, medium temperature drop, Material viscosity increases, blade fouling, Foreign matter stuck in kettle, Bearing lubrication failure lock, Both will cause motor overload.Final symptomatic treatment, Adjust process parameters to adapt to medium conditions, Shut down to clean up dirt on blades and foreign matter in kettle, Replace failed bearings, The equipment can be restored to normal operation.
Operation and maintenance pit avoidance, Motor overload condition not handled for 5 minutes, It is easy to cause motor burning, High equipment maintenance and shutdown losses, Timely investigation and rectification are required.
IV. Aging fault: bearing damage (accounting for 5% of faults)
Bearing damage occurs mostly in 3-5 years oldtitanium stirrerIt can be checked through three steps of listening, temperature measurement and life judgment.bearings in normal operation emit only uniform low frequency hum;A fine hissing sound indicates insufficient bearing lubrication;The cracking noise is track pitting damage;The click is a roller fracture, which is a serious fault.At the same time, it is equipped with infrared thermometer to detect the bearing seat temperature., ≤70℃ is normal, 70-90℃ needs attention, If the temperature exceeds 90℃, it must be stopped for maintenance.
Fault causes can be judged according to the operating life of the equipment, and abnormal conditions within one year of operation are mostly improper lubrication and installation errors;1-3 The annual faults are mostly caused by medium infiltration and short-term overload.3-5 The annual damage belongs to normal fatigue loss;For equipment running for more than 5 years, the bearings can be replaced regularly as needed.
Operation and maintenance pit avoidance, Bearing replacement needs to be replaced in pairs, Replacement of one side bearing alone will cause uneven service life of new and old parts, Failure occurs again in a short time.
V. Major failure: blade fracture (accounting for 5% of failures)
Blade fracture belongs to high-risk major fault, which needs to be shut down for troubleshooting at the first time.The root cause can be quickly determined according to the fracture position, blade root fracture, Most of them are weld defects, No annealing after welding, Long-term stress corrosionThe fracture in the middle of blade is caused by long-term erosion of medium containing solid particles and fatigue damage of blade.The fracture of the outer edge is basically caused by the impact of foreign bodies in the kettle.
Failure handling must strictly follow standardized procedures, shut down immediately, Open manhole inspection equipment, Thoroughly clean foreign matters in the kettle, After replacing damaged blades, post-weld vacuum annealing must be done, Eliminate welding residual stress.
Operation and maintenance pit avoidance, Operation with fault is prohibited after blade fracture, Continuous operation will cause the blades to hit the tank wall, Causing damage to the entire equipment, Large maintenance costs are incurred.
VI. Low-cost self-test tools and operation and maintenance summary
Daily equipment operation and maintenance can be equipped with three basic tools, Low-cost normalization self-test, Clamp ammeters are used to detect motor overload, Infrared thermometer monitors bearing and seal cavity temperature, Portable vibration meter detects vibration value of equipment, Low tooling input, Annual maintenance costs can be significantly reduced.Among the five types of faults,, seal leakage, Motor overload can complete basic maintenance independently, vibration, bearing, It is recommended to contact professional technicians for major blade failures.
