Product Certification
Product packaging 
1. Principles of Packaging Design
Protection Shock proof and buffering: precision accessories (such as instruments and valves) need to be filled with foam, bubble film, pearl cotton, etc. to avoid damage caused by transportation shock.
Moisture and rust prevention: Metal components (such as pipelines and flanges) need to be coated with rust prevention oil and packaged with moisture-proof film or vacuum. Desiccant should be added during sea transportation.
Anti pressure and anti drop: Heavy accessories (such as burners and drums) are reinforced with wooden boxes or steel frames, indicating the load-bearing direction and stacking layer limits.

2. Standardization and identification
Comply with international transportation standards (such as ISO, ISTA), indicate weight, size, lifting point, "fragile", "moisture-proof", "upward" and other markings.
Dangerous accessories (such as fuel injectors) must be labeled with UN certification and comply with the International Maritime Dangerous Goods Code (IMDG).

3. Container division strategy
Small items (bolts, washers) should be packaged in a uniform size box to avoid loose parts; Large items (heat exchangers) are individually customized in wooden boxes with supporting frames inside.

Product transportation
Transportation mode selection
1. Shipping by sea
Suitable for bulk accessories such as steel plates and large pipelines, pay attention to container size (20GP/40HQ) and load balance.Sea freight requires anti salt spray treatment, with moisture-proof agents placed inside the container and sealed.

2. Land transportation
Heavy accessories (over 3 tons) require flatbed trucks or low chassis vehicles, and routes should be planned in advance to avoid height/weight restrictions.Cross border transportation inspection of various countries' requirements for wooden packaging (such as ISPM15 fumigation certificate).

3. Air freight
Urgent small items (electronic controllers) should be prioritized for air transportation, and the weight of each item should be controlled (usually<100kg) to reduce packaging weight and save costs.

FAQ:
Common problems with gears in boiler accessories (one question, one answer)

Q1: What could be the possible reason for the loud noise during boiler gear transmission?
A1:  
-Tooth surface wear: Long term use leads to deformation of the tooth profile and unstable meshing.
-Poor lubrication: Lack of oil or deterioration of lubricating oil, increasing friction noise.
-Axis offset: Installation errors or bearing damage can cause poor gear alignment.
-Sudden load change: such as coal feeding machine jamming, causing impact vibration.
Solution: Check the lubrication status, recalibrate the axis, and replace worn gears.

Q2: What should I do if there is pitting corrosion (pitting on the tooth surface) on the boiler gear?
A2:  
-Reason: Contact fatigue, insufficient lubrication, or insufficient material hardness.
-Response measures:
-Replace gears with higher hardness (such as 20CrMnTi treated with carburizing and quenching).
-Use extreme pressure gear oil (such as ISO VG 220 high-temperature resistant lubricating oil) instead.
-Check if the load exceeds the limit to avoid long-term overload operation.

Q3: Common causes and prevention methods of gear tooth breakage?
A3: 
-Reason:
-Overload impact (such as the moment when a coal block gets stuck in the coal feeder).
-Material defects (such as casting pores or improper heat treatment).
-Fatigue fracture (caused by long-term alternating stress).
-Prevention:
-Install overload protection devices (such as safety couplings).
-Regularly inspect the tooth surface cracks (magnetic particle inspection).
-Choose materials with better toughness (such as 42CrMo quenched and tempered treatment).

Q4: What are the effects of high-temperature boiler environment on gears? How to select materials?
A4:  
-Impact:
-Lubricating oil is prone to failure and accelerates wear.
-Material strength decreases (carbon steel strength decreases above 300 ° C).
-Material selection suggestion:
-≤ 200 ° C: 42CrMo (quenched and tempered+quenched).
-200~400 ° C: 304 stainless steel or high-temperature alloy steel (such as 35CrMoV).
-High sealing requirements: ZCuSn10P1 bronze is used for the worm gear.

Q5: Possible reasons for the decrease in gear transmission efficiency?
A5:  
-Lubricant contamination (dust, water mixed in).
-The roughness of the tooth surface increases (due to wear or corrosion).
-Bearing damage causes additional resistance.
Solution: Clean the lubrication system, replace damaged parts, and check the sealing.

Q6: How to determine if gears need to be replaced?
A6:  
-Excessive wear: tooth thickness reduced by more than 10% (measured with a gear caliper).
-Tooth surface damage: severe pitting, peeling, or cracking.
-Abnormal operation: significant increase in vibration and noise, or unstable transmission.
