Ran under the circumstances, often vibration phenomenon, the existence of this shortened time to replace spare parts. The demolition process in the pump was found,cheap ugg boots, the protective tube connected sets of serious wear and tear, while the corresponding parts of the shaft is also worn. Transported through the pump pump structure in Figure 1 Figure 1. Pump cover 2. Impeller 3. Under the shaft 4. Pump 5. Protected tube bushing 6. Protected shaft tube 7. Axis 8.

Shaft tube of Nursing 11, 2007, Ge Ning. . not line environment and operation of the analysis found that the pump medium is sewage, which contains particles and oil,tory burch, retaining a non-wear parts shaft tube, the user general re-use them. Then in the process of re-use, retaining the connecting thread shaft tube had corroded, and care management is the series from the top down, while retaining the shaft tube threaded through positioning,uggs online bestellen, when the threads from corrosion, the cause of the change retaining tube thread size , prone to error during installation, the error will accumulate in series mode, which reduces the accumulated error protection pipe connected sets of installation accuracy. Protective tube sockets on the role of axial sliding bearing, the bearing clearance radius of normal working hours for the 0.115 ~ 0.147mm. When the protective tube sockets installed bias, then it will have on the eccentric bearing, shaft eccentricity will result in running wear, the gap will be rapidly expanding, which is detrimental to the rotor components. More severe cases, there will be a small gap to traverse the situation may arise, this time retaining tube to become unstable, thus retaining control of the entire shaft of the bearing bush. Axis of the supporting work in an unstable system. In this case, it is prone to vibration, shaft bearing parts can easily result in abnormal wear, the wear of the increased work environment led to the deterioration of the rotor, reducing the use of spare cycles. Fourth,uggs australia, technological transformation program, through technical analysis and consultation with users, make the following changes to the program r, with l; string = shown in Figure 3. Changed its protective tube connection, then sets of protective tube removed, added support in question,MBT schuhe, directly located in the center bearing support tube pump t, intermediate care and support through the shaft tube with the location, change the previous shaft tube direct care knot structure in series, they are separated by intermediate support section. Protection tube and the shaft supporting the connection asked the Ministry of Tacitus with the 0-ring seal in Figure 3 to modify the program 3. Care shaft tube 2. Support in Q 4,5. o-ring plastic 77 plastic 14, nCCW. . net development and design DesIgn & Dev Peng turned five, the program to a comprehensive analysis of the variant can be seen from the above, retaining the shaft tube in series, through the provision of nursing support shaft tube the way the shaft is changed, the revised plan enabled the middle bearing, relative of the original pump has the following advantages. 1) directly by the support tube positioning, installation is easy to ensure accuracy, independent of the protection tube, while retaining the shaft tube re-use, it will not change the accuracy of any impact on the supporting shaft. 2) improve the protection tube axis reuse, reduce maintenance cost and improve economic efficiency. 3) the middle branch of fixed position tolerance is better than retaining control bush supporting the structure will not be affected by water flow, the structure supporting the shaft to become more reliable. 4) positioning screw connection is changed, which enables the shaft tube is simple to install than before. Care shaft tube after remodeling will occur as the rotation axis of the operation; retaining axle tube seals can guarantee isolation and wear particles into the water to prevent the sliding bearings. Axis and the radius of care gap between the shaft tube is 8mm, the shaft surface is very smooth in operation, only the surface of the water close to regional impact, for 8mm shaft tube outside the protection of a minor ; care outside the tube axis of rotation is not pumping water, its protection has hindered the rotational axis of the role of management, while retaining the middle shaft support tube and the positioning of the average with zero gap, retaining both ends of the shaft tube surface has been pressed position fully guarantee the protection of these points the stability of the shaft tube, rotate is not possible. At the same time the static 0-ring seals to ensure a good seal. Add the intermediate support, the support tube flow area decreases, flow resistance increases, the performance of the pump have a certain influence. VI Conclusion 1OQL14 pump after modification, the whole production has been carried out, test the pump running smoothly, the performance point of data: the flow Q = 200m / h, the head H = 39.1m, this change was to within acceptable range. The pump delivered nearly 5 months without failure.
