Deep well pump bearing disassembly and installation technology of the three allow

Deep well pump bearing disassembly and installation technology of the three allow

1 allows the speed: the device is correct, good lubrication environment, allowing 0.3-0.5 times the bearing speed limit. Under normal circumstances, the appropriate 0.2 times the speed limit.
2 to allow the tilt angle: water pump bearings generally do not allow the tilt axis relative to the shell hole, such as tilt, less than 2
3 Allowable temperature: normal load, and the lubricant has the advantages of high temperature performance, adequate lubrication conditions, the total IKO bearings allow operation in the 30-150 ℃ temperature environment.
In addition, leaving a gap between 0.20.5mm should be hole seat and bearing NSK bearings, the device error caused by inaccuracies caused by parts processing, operation, the center of the bearing ring offset, the gap can ensure that its automatic adjustment to prevent contact friction ,normal operation. Bearing knowledge
Deep well pump bearing device is the correct seat can be automatically adapted to move moving, located in the upper and lower raceway. NSK bearing device, maintenance should be vertical axis and axis centerline. Otherwise, it will cause serious damage to the pump bearings, the device process requires careful attention, the heart should be fine, strictly according to the normal operation method.
Deep well pump bearing assembly and assembly have a certain principle is three allow, remember that three can be successfully installed and disassembled. According to the size of the size, location and conditions of use and environmental conditions, the accuracy of the appropriate bearing is to ensure bearing life and reliability of the premise.
