Js30 reducer is an important transmission device of scraper conveyor. During the operation of scraper conveyor, js30 reducer often has abnormal sound, oil leakage and high oil temperature. In view of the abnormality of js30 reducer of scraper, preventive measures should be taken during the use and maintenance to reduce the occurrence of abnormality as much as possible. Today, I'll teach you some tips on how to prevent the abnormality of js30 reducer. To prevent excessive noise of js30 reducer, first check whether the fixing bolts of js30 reducer are firm, whether there are impurities in the oil and whether there is enough oil in the oil tank, and then check if there is no problem. Due to the engagement maintenance of the internal gear of the reducer, the damaged parts shall be replaced in time. When js30 reducer works for a certain time, change the oil, check and add the oil on schedule. Regularly check the tightness of the sealing ring of the oil tank. If the sealing ring is aged and damaged, it must be replaced in time to prevent oil leakage of the oil tank. The tank body is reinforced and sealed with high matching components. Check the sealing of the closed part of the oil tank and the bearing cover to prevent oil leakage of the oil tank due to cracks and looseness. In order to prevent the phenomenon of too high temperature of js30 reducer oil, it is necessary to regularly check the reducer lubricating oil to prevent impurities from mixing in the oil, avoid using unqualified lubricating fluid, and ensure the proper oil volume in the oil tank. The radiator of oil tank shall be free of sundries, blocked and unobstructed, and the reducer parts shall be cleaned regularly to maintain the quality of parts. In view of the abnormal phenomena of js30 reducer of scraper, more attention should be paid to the daily inspection, maintenance and use process, which can greatly extend its service life.

Different main machine manufacturers of mine chain wheel components are equipped with different models, which are installed on the head frame of the head transmission part, mainly composed of bearing cover, bearing seat, sprocket body, sprocket shaft, oil seal, etc. How much do you know about mining sprocket components? Introduction to chain wheel components for Mining: There are two types of structure of sprocket assembly: split type and integral type. The structural advantage of the split sprocket assembly is that when the sprocket teeth are worn, only the sprocket body can be replaced or repaired instead of being replaced as a whole. And the integral sprocket is welded by the sprocket body and the roller, which is also often referred to as the "package sprocket". In this way, when the integral sprocket teeth are worn, they must be replaced or repaired in full. The basic requirements of the chain wheel assembly for mining are as follows: It has high strength, strong wear resistance, can bear pulsating combination and impact load, and has certain toughness; the tooth size parameter design is accurate, and the processing precision is high, so as to ensure good engagement between the chain socket and the chain, and avoid chain jumping and chain jamming.

As an important part of underground mining, scraper conveyor plays a role in transporting coal. In daily work, the phenomenon of chain jumping and chain dropping often occurs. There are many reasons for this phenomenon. Today we will discuss how to avoid it. We know that the components connected with the chain on the scraper conveyor are the scraper and the chain wheel assembly of the power department, thus forming the whole conveying working face. When the scraper conveyor is in normal operation, the scraper chain is fast and slow, and the chain speed is uneven. This is that the scraper chain is separated from the chain wheel, and it operates under abnormal conditions. Underground work, safety production is the premise. So we should do all the preparatory work: 1. First, ensure that the pitch error between the sprocket body and the chain mesh is not more than 1.0mm. Make sure that the chain socket is smooth and flat, so that the scraper chain and sprocket mesh smoothly. 2. The second is to define the position and angle of the head, so that the head and the second chute or base form a gap, so as to avoid uneven surface. The other is to ensure the coordination of the two chains in the normal operation process. It is forbidden to loosen and tighten one chain. The scraper shall be arranged in order and evenly distributed. The sundries in the sprocket groove shall be checked regularly and removed in time. 3. Since the scraper and sprocket assembly are all easy to wear parts after Zui, after using for a period of time, adjust the force direction of the sprocket or replace the sprocket with a new one according to the wear condition at the chain socket of the sprocket body. Remember to continue to work when the sprocket and chain are not stable to avoid unnecessary losses.

The working environment of scraper accessories is very bad. With the progress of science and technology, the major manufacturers of scraper conveyor in our country constantly use new technology to improve the quality and working conditions of scraper conveyor from the aspects of research and design, production and material selection. But in the actual work, the wear of scraper parts and the damage caused by external factors are inevitable. From the safety point of view, when the equipment is put into operation, its safety reliability is very high, but after using for a period of time, the safety reliability of the equipment will decline due to fatigue corrosion wear, so the scraper accessories need to be maintained, overhauled and replaced regularly, so as to avoid unnecessary loss and affect the coal mine production. When the number of times of the moving scraper reaches a certain value, the interface of the chute will affect the connection between the chute and the chute due to wear, and even the chute will be disjointed and overturned during the moving. Moreover, the wear between the scraper chain and the sprocket will increase the pitch of the circular chain. When the sundries are embedded, the scraper chain will be slotted at the head and tail of the machine. If it is stuck somewhere, the head and tail of the machine will be warped. These situations are not only the problems of the equipment itself, but also the hidden dangers that threaten the personal safety of the staff around the scraper accessories. Therefore, periodic maintenance and repair are needed to improve the safety and reliability of the equipment.

According to the analysis of the working principle, working condition and failure reason of the sprocket shaft group, the quality of the sprocket shaft group is not only related to the processing technology, but also to the material. The material and performance of the sprocket shaft group must meet the processing technology requirements of the sprocket shaft group. When selecting material of sprocket shaft group, its material performance shall meet the following aspects: Higher hardness The sprocket shaft group needs to be tempered during the processing, and the hardness after tempering should reach hb250 to hb280. The sprocket body and sprocket shaft need to be quenched, and the hardness after quenching should reach HRC50 to HRC55. Good toughness The toughness of the material determines the service life of the sprocket shaft group. The toughness of the material is good, which can effectively prevent the macro fracture of the sprocket and other problems, and also can inhibit the material removal caused by the fracture mechanism. Because the sprocket shaft group is used under high load, it is easy to produce fatigue cracks. The high plasticity and toughness of the material can reduce the generation of cracks. Excellent hardenability For the sprocket shaft group, good hardenability improves the ability to obtain martensite, which is conducive to improving the uniformity of quenching structure. High wear resistance In the process of working, the sprocket should be meshed with the ring chain, which will cause serious contact wear. Good wear resistance can improve the service life of the sprocket. Material 42CrMo The material of each drawing number sprocket shaft group produced by Luoyang vision is 42CrMo. Because 42CrMo is alloy quenched and tempered steel, its mechanical properties are better. After normalizing, tempering and heat treatment, the material has good hardenability, oxidation resistance, corrosion resistance, service life growth and is suitable for working face with bad working environment. Material and technology are the key factors affecting the quality of sprocket shaft group. When purchasing each drawing No. sprocket shaft group, select the material suitable for the working face according to the material and performance requirements of the drawing No. sprocket shaft group.

Due to the bad underground environment, geological conditions and three machine cooperation, scraper conveyor has serious wear and failure. In order to prolong its service life and improve its efficiency, let's analyze the reasons. Wear failure mainly includes: 1. The reducer has vibration noise or cannot bear heavy load Poor lubrication causes dry friction between gear teeth and bearings, or impurities exist in lubricating oil, resulting in poor engagement of gear teeth, resulting in tooth surface separation; the installed size does not meet the standard; the scraper has suffered intermittent hard impact in the working process for a long time. 2. The sprocket teeth are seriously worn or the bearing is damaged The chain is too tight, resulting in the increase of alternating pressure on the gear teeth; the sprocket assembly fails to rotate 180 ° in time for installation after 6 months of operation; the hardness is too high; the floating sealing property of the sprocket teeth is weak; the gap between the sprocket and the bearing is large, resulting in the damage of the sealing ring. 3. Wear of middle groove Under the bad working conditions, the middle groove bears the overload operation of the shearer, i.e. the heavy pressure of the shearer and the impact of the drum cutting the coal seam in the vertical direction; the large coal rock is stuck in the groove, the heavy pressure on the middle plate; the lateral and longitudinal forces of the push-pull hydraulic support. 4. The chain is seriously broken or worn. In addition to the sliding friction, the chain also bears a lot of static and dynamic loads, and is eroded by mineral water. Familiar with the causes of wear and failure of scraper conveyor, put forward preventive measures to achieve service life and improve production efficiency.

"Under the current situation of slow recovery of global economy and deep adjustment of China's economic structure, both the world and China's mining industry have entered a relatively difficult period. It is the only way to vitalize the metal mining industry to develop advanced and unconventional new mining theories and technologies -- Cai Meifeng, academician of the Chinese Academy of engineering. Open stoping, caving and filling are three common mining methods in metal mines. Because of its high cost, filling method is only used in some mines with high mineral value. In order to adapt to the requirements of green mining, reduce the environmental pollution caused by mining and damage to the ecological environment, it is necessary to fundamentally change the traditional mining mode and technology. 1、 Change of mining technology 1. Mechanical continuous cutting and driving technology From the long-term goal, it is an important direction to replace the traditional blasting mining technology with continuous cutting equipment by adopting the methods of mechanical driving and mechanical drilling. Because the blasting mining technology causes damage to the stability of surrounding rock, and the ore and waste rock are mined together, which greatly increases the workload of beneficiation and upgrading. advantage 1 & gt; mechanical cutting can accurately mine the target ore and reduce the ore dilution rate to Zui low. 2 & gt; can realize parallel and continuous cutting, loading and transportation process, which creates conditions for continuous mining. problem 1 & gt; the operation of mining machine is influenced by the variety of metal deposit forms 2 & gt; complex geological conditions and life and cost of cutting head 2. High pressure water jet rock breaking driving and mining technology High pressure water jet technology is a new cleaning and cutting technology developed in 1970s. At present, high-pressure water jet has been used to break soft rock and medium hard rock, which is widely used in coal mines. But when the hard rock is broken, higher water jet pressure is needed, which will reduce the reliability and life of the jet launcher system. In order to solve the problem of hard rock breaking, high-pressure water jet needs to develop towards the direction of ultra-high pressure and high power. It can be used to break rock under the condition of hard rock. 3. Laser rock breaking driving and mining technology Laser rock breaking is to use the heat generated by high-energy laser beam to heat the local rock rapidly. With the increase of temperature, the rock can be broken, decomposed, melted and vaporized in turn. Mining rock can be broken as long as it is broken. When the high-energy laser acts on the rock surface, the local thermal expansion of the rock rapidly results in the increase of local thermal stress. When the thermal stress is higher than the ultimate strength of the rock, the rock will be hot broken, and the rock will be cut. 4. Plasma rock breaking driving and mining technology This technology uses electric energy to change the electrolyte in the blast hole into high pressure and high temperature plasma gas, which expands rapidly to form shock wave and produces blasting effect similar to explosive. The pressure produced by blasting can exceed 2gpa, which is high enough to break hard rock. The implementation of this technology can greatly improve the working environment and reduce the impact and damage of traditional blasting on surrounding rock and environment. 2、 Support technology change 5. Paste filling mining technology Generally, because of the high cost, only some mines with high mineral value adopt filling method. However, in order to realize green mining, control the movement of rock strata and surface subsidence, protect the natural and ecological environment, effectively control the intense ground pressure activities of deep mining, and avoid the occurrence of various disasters caused by the instability and damage of roadways and stopes, the filling mining method will be the mining method that most mines, including iron mines, have to choose. This is a major change in the traditional mining model. However, the principle of balancing mining value and support cost should be abided by. In order to reduce the cost of filling, it is necessary to reform the filling technology and materials. Full tailings paste filling can obtain high quality filling body under the condition of low cement consumption, effectively maintain the empty area and control rock burst. It represents the development direction of this technology. 3、 Reform of integration of mining and beneficiation 6. Mining and separation integration technology Downhole pre selection and tail throwing technology. Before the ore is lifted to the surface, the ore lifting capacity can be significantly reduced by pre concentration and pre concentration in the underground and discarding most of the waste rocks. Pulp conveying technology. For deep mining, it is a potential technology to crush and grind the ore into slurry after pre concentration, and then send it to the surface concentrator by pipeline transportation. Compared with other transportation schemes, pipeline hydraulic transportation has a series of advantages, such as low capital construction investment, strong adaptability to terrain, no or less land occupation, little interference of continuous operation by external conditions, high degree of automation and reliable technology. The concentrator will be built underground. It is an important way to solve the lifting problem that concentrate is directly transported to the ground after underground beneficiation, which can greatly reduce the lifting amount of waste rock. At the same time, it is an important method to keep the waste rock and tailings in the mine for filling the goaf, realizing the original use, and reducing the pollution and damage to the ecological environment after discharging from the ground. Moreover, there is no concentrator or and tailings pond on the ground, which saves the cost of land acquisition and tailings pond management, and plays a role of more than one stroke. 4、 Mining technology change 7. No waste mining technology The goal of no waste mining is to reduce the output and discharge of waste materials to a large extent, improve the comprehensive utilization rate of resources, and reduce or eliminate the negative impact of mineral resources development. Therefore, mining activities should follow the view of industrial ecology, link the ecological environment, resource environment and economic environment of the mine, obtain the large resources and economic benefits of Zui with the small emissions of Zui, and fully protect the ecological environment. In order to realize waste free mining, first of all, mining method with small mining cut ratio should be adopted, ore dilution rate should be greatly reduced, Zui of waste output should be minimized, and waste rock output rate should be controlled from the source. At the same time, it is necessary to improve the level of beneficiation technology, improve the recovery rate of beneficiation, the comprehensive utilization degree and utilization rate of resources as much as possible, and reduce the discharge of tailings; develop innovative beneficiation technology and equipment, and reduce the unusable components of ore resources due to the low level of beneficiation and metallurgy to Zui. Through the methods of underground pre concentration and setting the concentrator under the well, the waste rock and tailings can not be discharged from the well, which can be used to backfill the goaf and realize the on-site and effective utilization of the waste from mining and separation. Strengthen the comprehensive recovery, realize the recycling of waste, improve the overall utilization level of waste, and strive to achieve zero discharge and zero storage of solid waste in mines.

The sprocket shaft group is a transmission part of the scraper chain operation, which is mainly composed of a shaft, a bearing, a bearing seat, a seal, a sprocket, and a positioning sleeve. So how to maintain the sprocket shaft group? The sprocket shaft group is lubricated with concentrated oil storage oil tank. The lubricating oil enters the sprocket shaft group through the oil tank, which makes it easier to refuel and prolongs the service life of the shaft group. After the sprocket set is replaced with new oil, it should wait for a period of time for the oil to reach the bearing and run at low speed for 2 minutes without the oil level passing the blind shaft. The sprocket body is forged from alloy steel. In order to increase its strength and extend its service life, it adopts quenching and tempering and surface hardening treatment. After one section is put into use, when the tooth surface on one side wears about 3mm, it is necessary to change the installation direction of the sprocket, change its force tooth surface and extend its service life. The sprocket shaft group stored as a spare part on the working surface is filled with working lubricating oil in the oil chamber to prevent internal rust. Regular rotation of the rotatable parts of the sprocket shaft set is required to ensure reliable lubrication of the bearings and non-condensing lubricant. Luoyang Yuanjian Mining Equipment Co., Ltd. was founded in 1996 and is a coal machine equipment expert with 24 years of experience. The company's scraper conveyors, scraper transferers and many other products have obtained national mining product safety mark certificates. The quality and safety of the products have been recognized, and the use of customers has been guaranteed. Regardless of technology and craftsmanship, they have absolute advantages in the same industry, and the business scope covers all major mining areas in the country. We are willing to cooperate wholeheartedly, develop together and create the future with your support. We use quality framework to build a bridge between us.
