A handsome §} Warming trend linked to the vibration on children, The inner and outer drum may occur between the bearing severe wear. W and axial clearance is too large or due to poor lubrication occurs because the bush near the feeding tube, the internal double oil seals and grease watts of $ 7108 may have been washed material. Which may cause wear or even in the shaft and axle tile. Wei and cause vibration plus point B than point A good working environment. Maintenance of the water almost in the same lubrication, A-point failure-prone than the B point. C, D of the working conditions and better working conditions than the point, and the material isolated. Thus the d-phase Yanshan Petrochemical us to point A as the core. Based on years of experience has shown several times, each time the direction of point A on the amplitude of slide bearing≥ 80p. m, the unit has a serious bearing wear. Can not continue to run, of course, caused by the vibration of the unit are many reasons, balancing the rotor itself is made good friends the direct cause of the vibration unit i, the outer rotor structure is relatively simple. Have been made prior to assembly, small balancing test. Balance the moment are in the allowable range. But also in the running of weight gain or weight loss will not be possible, because the ministries of the fastening components by snails. Although the material may stick to the drum itself, but has little effect on the drum itself. Moreover, the unit in operation,franklin marshall soldes, the continuous erosion by the materials, the possibility does not stick to the dogs. A point to prove whether the reason is that A vibration near the bearing problem, the point in the afternoon we make the addition of $ 7108.8 bearing on the measured data showed on l2. A point j_ direction amplitude 67rN. Slightly. Further confirmed that the point has serious bearing wear. By this time the condition remains unchanged, B, C,franklin marshall pas cher, D have increased the amplitude of each point. A, B point took place inside and outside the bearing wear. Had too due to the gap, and thus the introduction of C, D points of the chapter cited movement amplitude increased. And August l3 ~ ld after two days of monitoring further confirmed this view. Our timely development of maintenance strategies. That is, outside, inside the drum between the bearing and seal parts of the dismantling. Other parts do not move. Replacement of the spare drum. Only 7 hours to complete overhaul. And put into operation because only partial repair of the unit. Greatly reducing troubleshooting time. The unit in l986 April ~ August 1988 1d day,abercrombie pas cher, continuous operation 859 days. Nearly 20,000 hours, significantly reducing maintenance costs and increase the operation rate of equipment and plant capacity utilization. Continuous compliance for the PP plant production and lay the foundation. 3.4 Cross-diagnostic we rinse the unit supervisor. Usually selected amplitude as indicators for monitoring. But for some special cases. Specific point. We use Vrn63 amplitude at the same time remaining. Value is also used for cross-acceleration voltage Ying analysis in March 1990 we have two processes are similar. Structure exactly the same point C measured amplitude of the unit found. Two units in the C-point difference of about twice the amplitude. The other point is close to the amplitude values. However, point C is far from the maximum amplitude value is not exceeded, then change the speed measuring point C compared to 223-bit hole f [a plant called the fold Man hit jHsPM check the working conditions of the bearing point can be, for confirming our judgments - we the point bearing elm investigation found that the point of disintegration bearing slide with Ma Hang, timely replacement of small bearings. 4 to avoid the conclusion of a King incident gang through the use of any device described three processes (Figure dig) PP Zhuang enough already in operation i7 years old device. Heavy equipment accident in the aging high-mei. But we can keep equipment in good condition. Production year after year election mark. Actual production capacity exceeds the design level,christian louboutin pas cher, in addition to modify the equipment, the most important is to strengthen equipment management. Attained the status of the main unit to monitor the implementation status of the implementation of the host j = _ thatch small investment, big bear fruit. Barrier in the open on the unit during the period of high incidence of bribery test. Full play to the unit to contribute to the effective period. Lost no time and no damage to equipment, contribute more, which requires the group to conduct a comprehensive condition monitoring. The correct diagnosis. Literal-minded degree of maintenance to ensure continuous improvement of plant operating rates. To ensure smooth production. Large-scale implementation of a comprehensive state monitoring unit voltage. For continuous production of chemical equipment, so it is worthy of any sports' tt |
