As the application field of wire rope continues to expand, there are more people, so it is very important for how to distinguish the quality of the wire rope when purchasing. The following points are distinguished from the following points. 1. Packaging. The quality of the packaging wire rope is mainly reflected in the packaging. After the wire rope arrives, the rope wheel deforms, breaks, or the scattered rack causes the wire rope to roll, squeeze, abraduate, or non -moisture -proof measures on the rope wheels, causing severe rust and affecting the user. However, strictly speaking, it is not stopped. For example, the packaging does not meet the standards or contracts, and the order contract does not match the real objects of the delivery. The main reason for the above quality is: First, the manufacturer does not take care of the intensity when designing the rope. Methods Store equal to Article 78 of Chapter 78 in accordance with the provisions of Article 78 of the Coal Mine Wire Rope Inspection Technical Regulations. Those who violate one of the provisions in the acceptance inspection must be held accountable. The quality of the steel wire rope packaging is as follows: The rope wheels break and the packaging cloth to tear the rope in the loading and unreasonable hanging rope is crowded in the gap of the rope and cannot be removed. Disposal causes damage rope wheel strength insufficient rope wheel strength, after breaking, causing severe random rolling warehouse management disorders, disorderly stacking stacking warehouse management disorders, stacking like the lower rope wheels of the mountain, the steel rope cards and the steel ropes are in the library and the pier Burned. 2. Surface injury. Warves such as wounds, bumps, trauma, scratches, or nail wounds caused by the surface of the wire rope or wire due to contact with the external contact are called surface injuries, but during the manufacturing process The plastic deformation generated does not belong to the category of surface injury. If one of the following conditions is found during the inspection process, the responsibility shall be held accountable in accordance with the standards. Pressure: After the rope stock is crushed, the wire rope deforms, the rope stock is crushed, the rope diameter deformation causes uneven twisted distance, the stock gap increases, the stock gap increases, and the hemp core is exposed. Cause. Trocketing injuries: After the stock injury, it causes the hard bend convex hemp to expose, which is generally caused by the transportation. Hanging injuries: After the rope stock is hung up, the stock is unevenly loose; the rope rope is severely traumatized and scratched during the production process: this injury is a defect caused by transportation or loading and unloading. Essence Nail injury: The phenomenon caused by the inner layer injury on the rope nails has caused the inner layer damage, and the rope head nails are generally not a quality problem. Scratch: The outer steel wire is scratched by hard objects and caused the outer wire of the stock to loosen, which is generally caused by transportation. 3. Differential defects. The so -called twist defect, in a broad sense, is that all kinds of defects that are not in line with the requirements of the steel wire rope standards in the standard requirements of the wire rope in the twisting of the wire rope Defects, including: uneven twisting and loosening, the shift of the rope core of the stock, the rope stocks are severely loose and tight, the rope stocks are unblocked, a loose tightness is raised, and the multiple stocks are relaxed to varying degrees of relaxation Drum out, multi -layer stocks do not rotate steel wire rope outer layer of rope stocks relaxing, severe hemp core shift, tied with iron wire in the stock filament, causing the stock wire to relax and chaos, a serious relaxation chaos, no hemp core in a rope, Severely jump examples, severe twisting distances, etc. 4. The surface rust (rust). The oxidation phenomenon that appears on the surface of the wire rope (local or overall). The cause of rust (rust) on the surface of the new steel wire rope: First, the production of acidic, alkali, salt and other substances on the surface of the steel wire, the other is that the acid, alkali or moisture on the steel rope oil is too large, and the third is coating in the production of steel rope in production. Poor oil, fourth, is caused by improper packaging and moisture -proof measures (which are transported by its imported steel ropes through distances). The new rope (especially the user’s request to apply oil wire rope) is allowed to rust slightly, but after rubbing, there are still rust spots or those who have caused a pit and hemp to the noodles should be held accountable. 5. Dalvation defect. Galvanized steel wire galvanized steel wires have cracking, falling off, accumulation, zinc scars, and dew steel. The cause of galvanizing defects is mainly due to the pollution of galvanized wire surface oil or oxidative skin without washing off, and the galvanized process is not strictly controlled, such as zinc liquid vitality, temperature, equipment operating speed and stability, improper zinc residue treatment. 6. Poor oil. Poor oil is the phenomenon of the lack of and unevenness of the impregnation agent and lubricant on the surface of the wire rope or the hemp. The national steel wire rope standard stipulates: “Unless the user has other requirements, there should not be places on the surface of all steel wires in the wire rope.” This is also a measure to improve the quality of the wire rope. There are two types of steel rope oil used by the wire rope manufacturing plant: one is (impregnation agent) hemp core fat, and the other is an outer coating agent (surface fat). The main reasons for poor oil -applying oil is: First, the current domestic oil quality is not closed, but it is improperly immersed in oil. For example, when the wire rope is heated by heating the oil tank, the parking time is long, the oil temperature is too high, and the oil evaporation or leakage will cause poor oil. If this phenomenon is found, it should be taken to protect it in time. 7. The phenomenon exposed from the full length of the wire rope or the local stock wire gap is called the exposure of hemp. The reason for the exposure of the hemp core is that the thickness of the hemp core is uneven, the poor hemp joints increase or disconnect, and the rope stock twisting uneven factors are caused. Generally, there should be a small gap between the gap between the fiber core (hemp core) steel wire rope under normal circumstances. The use of disconnection and the use of steel wire ropes should be claimed to manufacturers. 8. After the end of the steel wire rope is loosened and cut off, the steel wire (all or part) of the stock or stock is released. Steel rope -rope wire loosening is mainly caused by improper pre -deformation and post -deformation process in manufacturing. Almost all countries have stipulated in the standard of steel rope: “………. After cutting the wire rope, the stocks and wires should not be loose.” Therefore, it should not be found that loosening should not be in the inspection. However, the wire rope produced by many steel wire rope factories has not been loose at all. 9. Poor joints. The steel wire in the wire rope causes the wire to be too large due to improper connecting method, incorrect linked center or poor welding. The main reason for the poor joints is caused by poor steel firing welding in the process of pulling wire, twisting stocks, or rope. It is serious that some steel wire rope manufacturers do not follow the standards according to standards. At the same time, we also found different diameters and other phenomena. Poor joints sometimes cause increased stock diameter, sometimes forcing the wire near the steel wire to dislocate. The welding head is thick and prominent, making the surface of the stock rope not smooth. According to national standards, generally fine steel wire ropes u003C18mm steel wire rope must not exceed 4 within 1000 meters, and important use of wire rope or fixed ruler wire rope is not allowed. 10. Steak (twisted twist). The phenomenon of protruding or falling in individual stocks in the wire rope, which is often produced at the same time as the stock wire loosen. The cause of these defects is: uneven thickness of the hemp core, the position of the tiles is incorrect, the pre -deformed card control is improperly controlled, the depth of each stock is inconsistent or the equipment is unstable. This phenomenon is not allowed, but if the end of the steel wire rope does not affect the order length, it can be dealt with. If it is affected, it should be claimed. 11. The loosening of the stock wire is the relaxation of the steel wire in the stock. The cause of these defects is mainly due to the large steel tolerance, the center wire is not enlarged, and the tightness of each worker wheel is not adjusted. Often, this defect is mixed with the stock wire staggered. Unexplained stocks will seriously affect the unevenness of the steel wire rope, and it is also prone to local wear. Generally, the steel wire rope has a minor stock loosening and allows it to exist. It is not allowed. 12. Steel wire cross. One or multiple steel wires appear on the surface of the wire rope, and the wire does not appear in the specified geometric location. This defects may appear when twisting stocks, and may also appear on the twist rope. During the processing, the wires on the processing wheel are unevenly loosening, and the line tiles are different. The center line of the disk and the axis is not vertical, or it may be caused by uneven twisting of the inner steel wire of the stock, with improper wire. During the inspection, it can be determined according to the delivery technical conditions. Generally, the general use of the wire rope must not exceed three within 1000 meters, but the important mining wire rope is not allowed. 13. Lack of wire (or running). It refers to the phenomenon of full -length or running wire or running wire in the wire rope stock. Most of the lack of wire or running wire appeared during the twisting stock. When the axis was uneven during the twisting stock, the blind axis was pulled off, the wire was crispy, and the width of the worker wheel was insufficient. Essence This defect mostly occurs in the inner layer in the multi -layer wrapped stocks. It feels a depression with hands. Sometimes it is wavy and the external wire deficiency is obvious. The wireless wire rope should be claimed to the manufacturer. 14. Jump. The phenomenon of one or more steel wires in the wire of the wire rope is raised or a bow -shaped or ring -shaped. The cause of this defect is mainly caused by the steel wire on the wire shaft with hard bending or division plate and rotating forming roller. In addition, when the rope is twisted, the tile is too large, and the steel wire on the worker wheel is uneven. This defect may occur. This kind of defect is the same as the broken silk, but it is easier to find than the broken silk. If there is a jump phenomenon in use, the raised part of the jumping part should be cut off in time, otherwise the part that jumps out will be pressed on the other silk except that it will be worn quickly and quickly wear out. At the same time, it also affects the life of other nearby steel wires. Generally, it must not exceed two wires within 1000 meters of steel rope, and important mining steel wire ropes are not allowed. 15. Broken wire. The wire rope filament refers to the phenomenon of individual steel wires in the new steel wire rope (expenditure or exposed on the surface of the stock). Most of the new steel wire ropes occur in the process operation of twisting stocks or co -rope. The wire was pulled, the wire was twisted on the shaft, the shaft wheel was stuck in the basket, the steel wire was crispy, and the electricity was poor. In the process of production of steel rope, the joints are particularly inevitable during the process of twisting stocks, and there are clear regulations in domestic steel wire rope standards. The wire rope should be avoided as much as possible, because it will directly affect the quality of the wire rope. For example, if the steel wire is large or the pimples appear, the stock rope will be raised, which will cause local wear when used. It often forms a stress concentration to make the steel wire prematurely break. If the toughness of the welding is too low or the hair is crispy, it will also cause fatigue to break. Therefore, in order to ensure that the manufacturers of all manufacturing plants must be strictly controlled, the wire rope is found in the acceptance of the inspection. Silk is not allowed, especially the mining of important use of steel wire ropes.
During the twisting stocks of the wire rope lack of wire or running wires, the axis was pulled off due to unevenness during twisting stocks, and the steel wire was crispy. Creating this defect. This defect mostly occurs in the inner layer in the multi -layer entangled stocks. It feels depressed by hand, sometimes wavy shape, and the outer wire deficiency is relatively small. Generally, it can be seen by the naked eye. Because the broken wire of the steel wire rope often occurs in the inner layer, the naked eye cannot be seen that users can determine whether the steel wire ropes have a problem of wirelessness by touching the method of touching inspection. On the one hand, the problem of stepping wires of steel wire rope requires enterprises to regulate production, attach importance to factory testing, and prevent unqualified products from flowing into the market. On the other hand, customers need to pay attention to selection when buying.
The wire deficiency refers to the phenomenon of full or a section of the rope stock of the steel wire rope or running in the rope stock. Usually, the wireless wire ropes will be checked when the factory is tested, and it is classified as unqualified products. So teach you how to identify whether the wire rope is broken.
