The excavator bucket is reinforced like this, and the result is twice the result with half the effort

The excavator bucket is reinforced like this, and the result is twice the result with half the effort

Veteran drivers know that the bucket is the most widely used work device in excavator operations, and it is also the work component that the excavator bears the most load during the excavation operation. In other words, the reinforcement of the bucket plays a very important role in the normal operation of the excavator. Today, the editor of Kangnai excavator accessories will tell you how to reinforce the excavator bucket.   There are data showing    An excavator consumes 4-5 buckets in an average of 8 years. Especially in the stone construction environment, the bucket wears faster, so the excavator bucket is a consumable excavator accessory. When the bucket is worn to a certain degree, the excavator master must reinforce the bucket in time to effectively improve its service life.   In the process of bucket reinforcement, most excavator masters have misunderstandings. It is generally believed that only a bunch of steel plates need to be welded at will. In fact, such blind reinforcement of the bucket will do more harm than good to the excavator itself. To reinforce the bucket, you need to master scientific reinforcement methods. The following editor will explain to you one by one.   Reminder    1. Reinforce the bucket of the excavator must be cautious and do not operate blindly; The manufacturing technology of    excavators has a history of more than one hundred years of development, and the bucket technology is also very mature. In the case of the bucket without excessive wear, a wide range of welding reinforcement plates will destroy the stress of the bucket itself, increase the digging resistance, and sometimes accelerate the wear and cracking of the bucket.    If the bucket is protected in all directions, it will increase the weight of the bucket. A heavy bucket will not only increase the fuel consumption of the equipment, but also work under high load conditions will have a considerable impact on the life of the equipment. Therefore, if the bucket is severely worn, it should be properly reinforced in a targeted manner rather than blindly reinforced.   2, attention should be paid to the reinforcement of the bucket of the excavator;   A technician with excellent welding skills is required to perform welding to ensure that the welding is firm and effective;   Partial welding is carried out to replace the overall welding in the parts that need to be strengthened most, avoiding the decrease of excavator efficiency and the increase of fuel consumption;   3. Experience sharing of excavator bucket reinforcement; Under normal circumstances, the side knife, bottom plate, side plate, and tooth root of the bucket are the places with relatively large wear. Therefore, the degree of wear in these places is regularly observed, and if necessary, these places should be strengthened. .    Tooth root strengthening: It is necessary to strengthen the tooth root mounting plate. In the daily work of the excavator, due to poor strengthening, severe wear will occur at the tooth root, and the bucket teeth will not be able to be installed for a long time. For the reinforcement here, two solutions can be adopted, one is to attach reinforcing ribs, and the other is to pack wear-resistant blocks. It should be noted that the method of attaching reinforcing ribs is simple and economical, but when welding, be careful not to overlap the welding seam of the tooth root, which will affect the welding strength of the tooth root. Bottom plate reinforcement: The bottom plate is an area with more serious wear and it is also necessary to strengthen the bottom plate. The reinforcing ribs of the bottom plate should be made of hard and wear-resistant long plates as raw materials. The overall shape of the bucket should be protected to avoid affecting the cutting angle. Affect production capacity. Many customers choose discarded chain plates as reinforcement materials. Personally think it is better. It should be noted that the welding of the ribs should follow the welding direction of the original machine ribs and overlap the two plates.    Side board and side reinforcement: The violent wear of the side board will reduce the effective bucket capacity of the bucket and affect the productivity. At the same time, the side knife also has the effect of cutting into the material and protecting the side board, so the bucket needs to be equipped with a side knife. Since the side is not a high wear area, the reinforcement of the side should not be too strong, so as not to affect the overall weight of the bucket.   4, maintain good operating habits;   The standard operating habits of the excavator master can not only improve work efficiency, but also reduce the wear rate of the bucket and protect the bucket.    To sum up, the correct method must be mastered to reinforce the bucket. Do not weld the reinforcing plate randomly, otherwise it will be too much. Some precautions for strengthening the bucket are introduced here first, hoping to have a
Excavator voice recognition failure

Excavator voice recognition failure

The excavator is composed of steel parts and is a large Iron Man. Regarding the problem of abnormal noise in the excavator, many old drivers think this is a harmless problem. In order to catch up with the construction period, they want to wait until the end of the project to deal with it in a unified manner. This is absolutely unworkable, beware of small problems that lead to big problems! Today, Weiwei will take everyone to listen to the problem. 1 Abnormal noise at the connection part of the working device ▊ Check whether the pin shaft is loose and whether the lubrication is in place. If the grease lubrication is not in place, grease should be applied in different positions to make the pin fully lubricated. 2 Abnormal sound of cylinder ▊ Check whether the hydraulic oil level is normal. Insufficient oil level may cause the main pump to be empty and produce abnormal noise during working load. This fault can be eliminated by checking the oil level. ▊ Check whether there are iron filings in the hydraulic oil or whether there are iron filings in the circuit. The iron filings may conflict with the piston rod and cause abnormal noise. ▊ Check whether the piston lock nut in the cylinder is loose and the piston moves back and forth inside. If it is determined that it is an abnormal noise in the oil tank, take it apart and look at it. 3 Abnormal sound in the rotating part ▊ Abnormal sound of rotating large gear ring: abnormal sound when rotating to a fixed position, it means that the large gear ring has abnormal sound. Check whether the amount of butter in the gear ring is normal; whether there is abrasion and foreign matter in the big gear ring. ▊ Abnormal noise in the rotating part Abnormal noise of the gearbox: Disassemble and check whether the planetary gears and bearings inside are loose or broken. Rotating motor abnormal noise: disassemble and check whether it is caused by the wear of internal parts. 4 Abnormal sound of pilot system ▊ Abnormal sound of pilot pump The gap becomes larger after the gear is worn. It is recommended to check whether the pilot pressure is normal. ▊ Abnormal sound of pilot oil pipe After the gears of the P3 pump are worn out, vibration and abnormal noise are caused due to insufficient oil supply. 5 Abnormal sound of safety lock lever The possible cause is that the filter element of the oil pipe connection position of the pilot handle is clogged, so the sound is heard. The clogging causes the pilot oil pressure to be insufficient, which affects the opening degree of the multi-way valve core, which causes the action to slow down. 6 Abnormal sound of hydraulic pump The 8 type machine has a noise reduction design on the hydraulic pump, so the sound will not be too loud, such as abnormal noise: ▊ First check the main pressure, it is best to contact a professional to do the performance test of the hydraulic pump. ▊ Confirm whether the two output oil pipes of the hydraulic pump are severely shaken. Pay attention to tubing jitter a. Whether the jitter of the tubing is caused by large pressure changes and instability. b. The pilot filter element is clogged and should be cleaned frequently to prevent clogging. c. Check whether the safety solenoid valve switch is abnormally switched. ▊ Confirm whether there is metal powder in the hydraulic oil return filter element inside the oil tank. If the above three points are normal, check the following aspects: 1 Confirm whether to use genuine hydraulic oil and hydraulic return filter element; 2 Whether the hydraulic oil is seriously polluted, it is necessary to replace the hydraulic oil regularly. The long-life hydraulic oil is usually replaced in 5000 hours. If the working environment is dusty, it needs to be replaced a little earlier. In addition, the excavator for crushing work needs to be replaced every 2000 hours. , Because once the hydraulic oil is contaminated, it is difficult to achieve its due lubrication and protection; 3 The oil path is not smooth, which may be due to insufficient hydraulic oil or blockage of the suction filter element, which damages the hydraulic pump after inhaling air; 4 The installation accuracy of the hydraulic pump is not enough; 5 The regulator and solenoid valve are not working properly, and the swash plate angle of the hydraulic pump cannot be adjusted to the required angle, causing the output flow of the hydraulic pump to not match the required flow, causing abnormal pump noise; 6 Due to irregular operation or overload operation, the impact on the hydraulic system is too large, and the pressure relief valve produces pressure relief sound; 7 Start to work when the heat engine time is insufficient, which will cause the hydraulic oil to have a higher viscosity, affect its fluidity, and cause excessive impact on the pump; 8 Whether the internal plunger of the hydraulic pump is worn or not, it needs to be checked and determined. 7 Abnormal sound of safety lock lever Abnormal engine n
The distinction of excavator bucket teeth

The distinction of excavator bucket teeth

Therefore, many machine friends want to find bucket teeth that pass the process, quality, and wear resistance. This saves the cost of replacement on the one hand, and saves a lot of replacement time on the other hand. The following editor will give you a detailed introduction on how to select bucket teeth from the aspects of process, material, pores and physical comparison. To Process manufacturing: To At present, the best technology on the market is forging bucket teeth. Because of the high density of forging technology, bucket teeth not only have high hardness but also have very good wear resistance. Of course, the price is also a lot more expensive. The ordinary casting process is clearly distinguished from the forging process bucket teeth in terms of price. Of course, the feedback also has obvious differences in details such as the wear resistance and hardness of the bucket teeth. To Stoma To When a knowledgeable old driver first buys a bucket tooth of a certain brand or manufacturer, he will conduct detailed observation and inspection, even cutting. By observing the pores after cutting, you can tell whether the quality of the bucket tooth is too hard. The pores of castings are generally divided into separating pores, intrusive pores and reverberating pores, and the formation of shrinkage cavities and shrinkage porosity in castings is mostly accompanied by the separation of gas. The pores, shrinkage cavities and shrinkage porosity can be said to be associated . To To put it simply, bucket teeth processed with good technology and material have very few pores, and you will not see large, spherical or group-shaped pores after cutting. On the contrary, bucket teeth with general manufacturing technology and material. To Real picture comparison To Let's make a physical comparison. First, we will select the ones with good craftsmanship, ordinary craftsmanship and slightly worse craftsmanship from the three bucket teeth sold on the market, and we will introduce them in detail: To High quality: high surface gloss, smooth touch To Normal: There are bumpy particles on the touch, and the gloss is slightly poor To Inferior quality: obvious frosted graininess, thick paint Tooth tip thickness: The tip of high-quality bucket teeth will have a significant thickness difference than that of inferior models, which is why ordinary bucket teeth wear out after a period of time. Bucket tooth weight: According to the weighing point of view, the weight of inferior bucket teeth is the highest, followed by high-quality models, and the lightest is the ordinary model. It can be seen that although bucket teeth are distinguished by weight to a certain extent, they are not Not 100% accurate! Therefore, when some manufacturers use bucket tooth weight as a gimmick, everyone should pay special attention. To Tooth replacement cycle To The construction environment of an excavator directly determines the degree of wear of the bucket teeth and the frequency of replacement. For example, if the excavator is doing earthwork or sandy soil engineering, it is almost the same as replacing it twice a year, because the degree of wear will be much smaller. To However, if it is a quarry or rock project, the replacement cycle will be much shorter, especially for granite and other hard stones. It is commonplace to replace it once a week. Therefore, the quality of the teeth, the operation method and the construction environment determine the teeth. Replacement time. To to sum up To All in all, understanding the manufacturing process of bucket teeth, observing the number of pores on the cutting surface of the bucket teeth, as well as the weight and other details, can judge whether the quality of the bucket teeth is satisfactory.
