Three methods to teach you to reduce the wear of the middle groove of the scraper conveyor The middle groove of the scraper conveyor is affected by factors such as the complex environment of the coal mine and its own design limitations, and is very prone to wear. If the wear of the middle groove of the scraper conveyor is not solved in time, it will seriously affect the transport capacity of the scraper conveyor and even affect the production of the coal mine. Luoyang Foresight today teaches you three ways to reduce the wear of the central groove. Proper operation and maintenance Improving the quality of personnel can effectively reduce the wear failure of the central groove of the scraper conveyor. Coal mining companies should provide technical training to the operators of the scraper conveyor, for example: the idler is prohibited from idling when there is no material to carry, reducing unnecessary energy consumption and wear; keep the work surface flat and straight before starting the scraper conveyor, Prevent the two scraper chains from wearing unevenly and wear; the middle slot and scraper chain should not be overloaded or run for too long at one time, otherwise fatigue and wear will occur. Reasonable selection of wear-resistant materials At present, the material of the central groove of the scraper conveyor in China is mostly 16Mn steel, and the wear resistance of this material is still a certain gap compared with the alloy steel of advanced foreign countries. Choose low-friction, anti-friction materials. In addition, the correct heat treatment process can also increase its abrasion resistance. Coal mining companies should choose powerful manufacturers and carefully consider their manufacturing processes when purchasing central tanks. Luoyang has seen 24 years of coal machinery equipment experts, and its products are trustworthy. Surface coating technology A surface coating is a thin film of one or more layers of material applied to a solid surface to strengthen the surface. Common coating methods include surfacing and thermal spraying. When selecting the middle slot of the scraper conveyor to apply the coating, the coating material should be selected according to the work conditions and coating properties of the workpiece. A coal mine enterprise can reach a cooperative relationship with a manufacturer. When the surface of the middle groove is severely worn, it is quickly sent to the manufacturer for surface treatment to prevent its wear from rapidly deteriorating. The middle groove of the scraper conveyor can effectively reduce the wear through reasonable design, material selection and heat treatment. Coal mining enterprises must choose a strong manufacturer when purchasing the central slot of the scraper conveyor, comprehensively review the production process, especially the above process, and then purchase. Luoyang Yuanjian Mining Equipment Co., Ltd. was established in 1996.

The abrasion of the middle groove of the scraper is mainly the abrasion of the middle and the groove side, especially the wear of the joint of the two sections is more. Aiming at the cause of the failure of the central groove of the scraper, improvement measures are proposed, which can not only reduce the wear on the central groove, but also reduce the wear of the scraper conveyor accessories.The improvement measures of the middle groove of the scraper can be considered from the following aspects:Point 1Made of high-strength wear-resistant material At present, the common material for scraper conveyors is high-manganese steel. The strength and wear resistance of high-manganese steel are relatively good, but this material also has shortcomings. Faced with a complex underground operating environment, high manganese steel has poor corrosion resistance, is susceptible to rust, and has a short service life. Although high manganese steel has good wear resistance, it has a large friction coefficient and consumes a lot of energy. In order to improve the defects of the current central groove, a material with good abrasion resistance, low friction coefficient and corrosion resistance should be used. The main materials.Point 2Strengthening the surface of the central grooveStrengthening the chute surface can not only reduce the friction distance between the scraper and the chain in the middle groove, but also improve the service life of the middle groove. At present, high-manganese steel is used in the chute. In addition to changing the composition during the improvement process, it should also be strengthened. DRR-2 numerical control technology can be used to partially cover the surface of the central groove to enhance the wear resistance of the material. Strengthening the chute surface can not only reduce the friction distance between the scraper and the chain in the middle groove, but also improve the service life of the middle groove.Point 3Strengthen the maintenance management of scraperIn the management and maintenance of the scraper conveyor, first of all, before the installation, the inspection of the parts of the scraper conveyor should be done to ensure the quality of the machine parts. Second, during the installation process, the installation position of each component of the scraper conveyor should be determined. Each component should be installed straight, and the left and right staggers at the middle slot interface, headstock, tailstock and transition slot interface should be Less than 3mm. For excessively worn links, a new chain replacement should be used. When the chute is fully loaded, the amount of double chain sag of the head empty chain should be 60 ~ 140mm, and the single chain should be 30 ~ 100mm. Furthermore, in the process of pushing the scraper conveyor, it should be ensured that the distance between the curved part of the scraper conveyor and the shearer should be more than 16m, and the bending length should be greater than 13m. Accidents such as chain breaks due to misalignment of the chute. After Zui, after the installation is completed, it should be inspected in strict accordance with relevant standards, especially the fluid filling capacity check of the hydraulic coupler, which should be matched with the motor. In addition, the chute should be cleaned regularly to ensure that the chute working environment is clean.Point 4Do rust removal and surfacing workSince the scraper conveyor is susceptible to rust, the rust removal work of the welding part should be done well. During the transportation of coal mines, the problem of abrasion is likely to occur on the coal crossing surface and the floor of the middle plate. To this end, the company should also do the overlay welding of two parts and use welding materials with better wear resistance to obtain better quality Grind the protective layer. After finishing the welding work, it should also do a good job of sanding to ensure the smooth passage of the coal scraper. Coal mining enterprises should prolong the life of the central tank of the scraper from the aspects of purchase, installation and maintenance. 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.

In order to save costs and achieve the goal of saving costs and reducing consumption, many coal mines usually repair and overlay the middle groove of the scraper conveyor with less severe wear. The following will reveal the "secret" of wear resistance after repairing the middle groove of the scraper conveyor. Descaling and descaling process Due to the adverse environmental conditions in the underground, the middle groove of the scraper conveyor will rust during the use in the coal mine. In order to reduce the impact of impurities during welding, the welding position of the middle groove of the scraper conveyor should be started before the welding process starts. Descaling is performed, and the middle groove of the unused scraper conveyor is protected by painting. Surfacing process Warm up Because the overlay welding process requires temperature, in order to reach a certain temperature before the overlay welding, the construction site of the middle tank and the welding material must be heat treated. 2. base Since the hardness of the central groove body is different from that of the wear-resistant material, if no bottoming measures are taken, the groove body and the wear-resistant layer are prone to delamination and fall off under stress. Therefore, it is necessary to adopt Overlay transition layer measures. 3. Insulation After the priming process is performed, the required priming site needs to be insulated to maintain a certain welding temperature. 4. Wear-resistant treatment Use the "self-fluxing alloy fusion surfacing method" to wear-resistant the wear parts of the chain, and fill the wear parts with the welding material; use the high-wear resistance welding material to the chute middle plate and the bottom plate scraper that are prone to wear problems Overlay welding is carried out to ensure that the site has a wear-resistant protective layer. 5. Polished After the surfacing welding is completed, use an angle grinder to grind the slag on the surfacing area to ensure the normal operation of the scraper. Through the above abrasion-resistant process, the service life of the middle groove of the scraper conveyor can be effectively extended, which is the "secret" of increasing the wear resistance of the middle groove after surfacing repair. Luoyang Yuanjian Mining Equipment Co., Ltd. produces various types of scraper accessories, reprinter accessories, etc. The products have higher wear resistance than the same industry, and the quality of the products is well-known. If necessary, you are welcome to come and buy.

Scraper conveyor is the first link of coal transportation. The quality of its operation determines whether coal safety production can be carried out smoothly. During the operation of the squeegee conveyor, the chain breaking of the squeegee chain occurs from time to time. What causes the chain breaking of the squeegee chain? Today Luoyang Vision will answer this question for you. Scraper chains are not paired The scraper chain is composed of a ring chain, a scraper, a bolt, a pressure plate and a lock nut. Scraper chains are usually used in pairs, so they must be paired. If there is no pairing, the length of the scraper chain is different, and the stress of the scraper chain is concentrated on one of the ring chains for a long time. Chain break accidents are prone to occur when the conveyor is running Link chain model is incorrect The strength level of the round chain must match the power of the scraper conveyor, the chain speed, and the high zui tension of the chain when starting at full load. If the ring chain is not selected properly and the strength level is insufficient, the chain will be broken during operation. Especially when starting at full load or when iron is dropped on the scraper conveyor, it will cause frequent breaks. The chute chain does not match the size of the scraper The size design of the lower chain of the chute of the scraper conveyor is also very critical and needs to match the size of the scraper. For example, the length of the scraper needs to match the width of the chute, and the height of the scraper must match the height of the lower chain of the chute. If the clearance between the scraper and the lower chain is very small, when the scraper conveyor is bent, the scraper will trip in the lower chain of the chute, plus the influence of coal return, it will often trip the chain, and then in the lower chain. Strangling the scraper chain caused a chain break accident. Excessive misalignment at the chute interface Due to the manufacturing error of the manufacturer, the pushing time is too large, the amount of misalignment at the chute interface caused by the bending and deformation of the interface board at the two ends of the chute, etc., will cause the scraper to trip during the operation, resulting in a chain breaking accident. . Scraper "out of slot" During the operation of the scraper, the friction with the chute is continuous. Friction will eventually cause the wear of the scraper to become shorter and the wings to wear. When the scraper is worn for a long time and its length is less than the slot of the chute, it is very easy to appear "phenomenon. If the "slot out" scraper is not found in time, the scraper will run to the head sprocket, and it will catch with the head frame and cause a chain break. Aiming at the above-mentioned reasons that may cause the scraper chain to break, find out the corresponding measures, which can reduce the failure rate of the scraper conveyor, reduce the number of abnormal shutdowns, and ensure the normal operation of safety production in the underground. Luoyang Yuanjian Mining Equipment Co., Ltd. looks forward to cooperating with you!

The vibration machinery and equipment used in the mining machinery industry must not lack one thing in production, that is, lubricants. Mining machinery and equipment have certain technical requirements for the selection of lubricants. It is not to say that any one can be used at will. Today, let's simply popularize the selection of lubricants in mining machinery and equipment, as follows: 1. The size of mining machinery and equipment is not exactly the same But in general, it is relatively large, but the oil tank capacity of mining machinery and equipment is relatively small, so the amount of lubricating oil installed is relatively small, so when the mining machinery and equipment are working, Higher temperature will also appear, which requires that the lubricating oil has better thermal stability and oxidation resistance. 2. The use environment of mining machinery and equipment is relatively harsh There are more dust impurities, so the lubricating oil is more susceptible to contamination, so it is required that the lubricating oil filled inside the mining machinery and equipment has relatively good rust and corrosion resistance and basic properties of anti-emulsification; and It is required that the basic properties of the lubricating oil cannot be changed greatly, and the sensitivity to pollution is also small. 3. When the mining machinery and equipment are used in the open air The temperature change in summer and winter is very large, so the viscosity change of this lubrication is required to be relatively small. It cannot be said that at high temperatures, the viscosity is low, and a lubricant film cannot be formed. , The viscosity is too high, so that starting and running are more difficult. 4. Lubricants should have good flame resistance to avoid fire and explosion If it is said that mining machinery and equipment are used in some places prone to fire and explosion accidents, then it is required to use a lubricant (flammable liquid) with good flame resistance, and cannot use flammable mineral oil.
