Buldozer Copper Ring Method

1. Daily cleaning

1. Cleaning frequency

After each working day, the copper ring of the bulldozer should first be cleaned. This allows you to quickly remove dust, dirt, butter and other pollution, adhering to the surface of the copper ring during the day of operation, preventing the prolonged accumulation of these contaminants and the occurrence of wear or corrosion of the copper ring.

2. Cleaning tools and materials

Soft brush: use a soft brush, for example, from a boar bristles to gently brush off dust and dirt from the surface of the copper ring. The bristles of the soft brush have a soft texture and do not scratch the surface of the copper ring, which allows you to effectively protect the accuracy and quality of the surface of the copper ring.

Cleaning: Use a specialized cleaner for metals, for example, designed for copper. This cleaner effectively removes oil and light oxide layers, without causing corrosion of copper rings. Avoid the use of cleaning products containing strong acids or alkalis so as not to damage the copper ring.

Pure fabric: Prepare a clean cotton fabric or dust without dust to wipe the detergent and pollution, making sure that the surface of the copper ring is clean and dry.

(III) Cleaning stages

First, use the brush with soft bristles to gently brush off dust and dirt from the surface of the copper ring. Spread evenly with a brush around the circumference from the inner circle to the outer circle of the copper ring to make sure that each part can be cleaned.

Spray the required amount of detergent to the surface of the copper ring, but be careful and do not use too much product so that the detergent does not get to other parts and does not cause damage.

Gently wipe the copper ring with a clean cloth to remove oil and detergent. Some persistent spots can be wiped several times or gently rubbed with a soft brush, but be careful not to damage the copper ring.

After cleaning, wipe the copper ring dry with a clean cloth so that there is no moisture on the surface and prevent rust on the copper ring.

2. Lubrication maintenance

1. Lubrication frequency

Lubricate the copper ring regularly depending on the frequency of use and operating conditions of the bulldozer. As a rule, lubrication must be done every 50-100 hours of operation. In difficult working conditions, such as high temperature, high humidity, dust, etc., the lubricant cycle should be reduced accordingly.

(Ii) selection of lubricants

Choose lubricants suitable for copper rings, for example, lubricant based on copper or special lubricants resistant to high temperatures and wear. Lubrication based on copper has good adhesion and corrosion resistance, and can also form a protective film on the surface of the copper ring, reducing friction and wear. Special additives are added to special lubricants in accordance with the working characteristics and requirements of copper rings to better satisfy their lubricants.

(III) Lubrication method

Before lubrication, clean the surface of the copper ring so that the lubricant can fully stick to the copper ring.

Use a special lubricant tool, for example, a lubricant syringe or a brush to evenly apply grease to the surface of the copper ring. For copper rings installed on the shafts, make sure that the lubricant is evenly distributed along the internal and external rings of copper rings, as well as on the surfaces that are in contact with other components.

When applying lubrication, be careful and do not apply too much lubrication so that it does not result in and does not pollute other details. At the same time, make sure that the lubricant is applied evenly to avoid a local lubrication lack.

3. Regular inspection

1. The frequency of checks

Carry out a comprehensive check of the copper ring through regular working hours or run intervals. It is usually recommended to check every 200-300 hours of work or once every two months. During the inspection, carefully inspect the copper ring for wear, deformation, corrosion, etc., in order to detect potential problems in time.

(II) The content of the audit

Checking wear: use measuring tools such as caliper or micrometers to measure the thickness, inner diameter and external diameter of the copper ring, compare them with the initial dimensions and determine the degree of wear of the copper ring. If the wear of the copper ring exceeds the specified tolerance range, this may affect its normal work and requires timely replacement.

Checking for deformation: Check if the copper ring is deformed by visual inspection or using special detection tools. If the copper ring becomes elliptical or twisted, the accuracy of conjugation with other parts will decrease, which will affect the performance of the equipment. It should be replaced or replaced in time.

Corrosion check: check if there are corrosion or rust stains on the surface of the copper ring. If corrosion is detected on the surface of the copper ring, the cause of corrosion should be analyzed, for example, whether it is caused by chemicals, moisture, etc. In the working environment. Minor corrosion can be eliminated by cleaning and applying a protective agent; In the case of severe corrosion, a copper ring should be replaced in time.

Checking of landing: Check the landing of a copper ring in relation to other details, for example, the tightness of the landing in relation to the shaft, the bearing nest, etc. If it is found that the planting is not loose, this can lead to the movement or vibration of the copper ring during operation, which will affect the stability of the equipment, so the corresponding parts must be adjusted in a timely manner or replaced.

4. Elimination of problems

1. Elimination of wear and breakdowns

If the copper ring is slightly worn, it can be repaired with grinding. Use special grinding tools and grinding paste for grinding the worn surface of the copper ring to restore it to a given size and surface accuracy. During the grinding process, pay attention to the control of force and direction of grinding to avoid damage to the copper ring due to excessive grinding. If the copper ring is strongly worn out and its service life exceeds the repair life, it should be replaced in a timely manner with a new one. When replacing copper rings, choose products of the same model and with the same characteristics as original copper rings to guarantee their performance and installation accuracy.

(Ii) processing defects of deformation

To eliminate minor deformations, you can use correction methods. Use a special correction tool, for example, a press or a corrective device, to slowly return its original shape to the copper ring. During the calibration process, pay attention to the control of the strength and speed of calibration to avoid damage to the copper ring due to excessive calibration. If the copper ring is very deformed and is not subject to repair by correction, it should be replaced in a timely manner with a new one.

(III) elimination of malfunctions associated with corrosion

If corrosion appears on the surface of the copper ring, then it is necessary to first remove corrosion products. You can use sandpaper or metal brush to carefully polish the corroded area and remove corrosion products. Then clean and dry the corroded parts and apply a protective agent, for example, anti -corrosion paint or anti -corrosion coating to prevent further corrosion of the copper ring. If corrosion influenced the performance and strength of the structure of the copper ring, replace the copper ring with a new one in a timely manner.
