1、英文原文Commissioning of the belt conveyor and automatically tighten its hydraulic device of Hydraulic belt conveyor automatically tensioning device is based on tape and in normal operation at the start of the strain of the different needs of the tape, after reasonable analysis of tension model designed
2、 Hydraulic automatically tensioning device is the traditional way tighten the upgrading products can be widely used in coal, metallurgical, power plants, cement plants, terminals and other bulk material conveyor belt of the take-up equipment. Belt conveyor after two centuries of development. Has be
3、come from the initial prototype development with a high-speed, long distance, high-power, the capacity of modern means of transport, belt conveyor widely used in metallurgy, mining, chemical industry, ports, power plants, light industry, building materials and food And many other enterprises on the
4、field. Because of their steady and reliable work belt conveyor, the noise of small, simple structure and operation of low-cost, anywhere in feeding or unloading. Has become a major granular material transport equipment one. As the conveyor belt of the viscoelastic properties, in order to ensure belt
5、 conveyor running the necessary friction, we must provide a suitable strain of. Tension belt conveyor device is an important and indispensable component of its properties have a direct impact on the overall performance of belt conveyorsConveyor belt by the nose, tail, drive, drag roller, roller, ask
6、ed planes, belts, consisting of cleaning, etc. Conveyor belt installed in the end, officially put into use, the equipment needed to debug.1. A conveyor belt of the debugging process 1.1 belt conveyor belt conveyor belt deviation running belt deviation is the most common fault. Failure to resolve the
7、 focus of attention should be paid to such installation of dimensional accuracy and day-to-day maintenance. Deviation due to a combination, depending on the need to address the reasons for differences. Such as:1.1.1 adjustment drag roller bearing GroupThe belt-belt in the central belt of the transpo
8、rt plane deviation, they can drag roll by adjusting the group to adjust the location of deviation. Specific method is biased belt which side of the trailer roll group which side of the direction of advancement in the belt, or the other side after the shift.1.1.2 adjustment bend drum-driven drum and
9、the location of drum-driven drum and bend the adjustment deviation adjustment of the belt is an important link. Because a belt transport planes at least 2-5 drum, drum all the installation location must be perpendicular to the length of the belt transports the centerline, if skewed too much inevitab
10、le deviation.1.2 unusual noiseRunning its transport belt drive, drive pulley and bend drum roll and drag Group, is not normal in abnormal noise will be issued, according to the abnormal noise judgement of equipment failure.1.2.1 serious drag roll eccentricity when the noise. Conveying belt running t
11、ractors will happen very often roll noise and vibration mix is cyclical. In particular, is a return drag roll, because of their greater length, its own weight, and also more noise. Noise in the two main reasons: First, manufacturing tractors roll of seamless steel pipe wall thickness uneven, the gre
12、ater the centrifugal force and the other is in the processing of bearings at either end of the round hole with the heart of bias, so that was too large centrifugal force . Bearing in not allowing the noise and damage to the existence of too large. Bearing in not allowing the noise and damage to the
13、circumstances may continue to use.1.2.2 shaft coupling the two different heart when the noise. In the high-speed drive motor-reducer and asked the coupling of the band or brake coupling Department issued a round of the unusual noise, the noise and also with the same frequency of rotating motor vibra
14、tion. This should be a noise reducer in time to motor to adjust the location, in order to avoid reducer input shaft fracture. 1.2.3 bend and rolling Chien Chien-driven roller abnormal noise. Bend and drum-driven drum normal working hours noise is very small, unusual noise in general is damaged beari
15、ngs, housings Department issued Kaka beep, at this time to replace bearings1.3 belt skid.Tensioning device using a heavy hammer of the belt when the plane skid in the belt to add weight to resolve, added to the belt so far not slippery. But should not add too much, so as to keep the belt too much to
16、 bear unnecessary tension and reduce belt life.2. tensioning device research2.1 tensioning device featuresIn the course of running belt conveyors, should be able to solve the start-up, parking at the tape skid, and the impact of the loss of tension and other issues, with the use of the belt conveyor
17、 continuous expansion and the constant development of science and technology, and rational design tensioning device It is particularly important. Tensioning device functions in the following points:2.1.1 ensure that the tape drive from the point of roller Ben sufficient tension, thus ensuring drive
18、must rely on the friction drive transmission friction traction, driven conveyor to the normal operation , The conveyor system to prevent skidding.2.1.2 ensure that the smallest branch of carrying the tension point must be tension, restrictions on the conveyor belt in the roller asked the sag, and en
19、sure normal operation of belt conveyors, not because of the conveyor system down through the vertical jump impact caused the coal roller Losses caused by the electrical energy and the materials, such as flesh littered the phenomenon. 2.1.3 compensation tape and plastic deformation transition conditi
20、on elongation qualitative change. As load will cause changes in the length of the conveyor system changes, creep phenomenon may cause conveyor belt extension, the tension there is a change in the trend of small, to absorb the need tensioning device by the creep of the SIN, to maintain normal operati
