(1) rolling bearing in operation in different sound and high temperature
　　
â‘ bearing quality problems. Check the bearing should pay attention to the appearance of the bearing, rolling body is flexible, bearing the size of the gap and other parts.
　　
â‘¡ bearing sleeve. When the bearing housing temperature is high and there are different sound, large amplitude small, vibration cycle indefinite, disintegration inspection found that the outer surface of the bearing outer wear marks, and the gap is too large, the bearing and running sleeve, available adhesive, make up Welding, set of methods to repair. Serious set, can not be repaired with the above method to be replaced.
　　
â‘¢ serious bearing wear or damage. Bearing running loud noise, and high temperature, amplitude, need to replace the bearing.
　　
â‘£ axial force is too large. For the cantilever pump (IS single-stage single-suction centrifugal pump), bearing temperature near the pump head is too high, and disintegration found by the pump head bearing raceway and rolling body found that the surface of the oil, lubricating oil inside the metal powder, black oil , While the other end of the bearing intact, the pump may be too large axial force, the bearing temperature is often too high, resulting in bearing damage. If it is a double bearing pump, the location of the bearing is too high, and the vibration is loud and the noise is loud. At this moment, the radial bearing, temperature, sound and vibration are normal, but also the bearing temperature caused by the excessive axial force High, the disintegration will find two centripetal thrust bearings wear more serious, raceway and rolling body Ma Hang. Approach is to balance the axial force.
　　
⑤ bearing axial positioning problems. Pump operation, the temperature is high and the vibration is not large, the bearing axial clearance may be too large, after parking, gently tap the tool with a tool found that the backrest wheel has obvious axial movement, the need to re-adjust the gap.
　　
(2) horizontal single-stage centrifugal pump rolling bearing operation, no different sound, but the temperature is high
　　
â‘ cooling water problems. Cooling water temperature is too high, the cooling water may not open or blocked, insufficient, need to clear or adjust the cooling water,
　　
â‘¡ too much oil, too little or bad oil. Hand touching the bearing temperature before and after the high, need to adjust the lubricating oil.
　　
â‘¢ bearing assembly gap or gland gap is small. At this time more difficult to crank, indicating that the gap should be re-adjusted.
　　
â‘£ vibration problems. Due to the vibration caused by the bearing temperature is high, we must first solve the vibration problem, eliminate vibration.
　　
⑤ rotor center and bearing box hole, a large lid different heart (bearing box or pump cover deformation). For the above reasons have been inspected still can not be resolved, can be considered as a large bearing housing or pump cover partial bearing shaft before and after different. The bearing load increases, wear increased, the temperature is too high, this situation can only be corrected on the lathe.
　　
â‘¥ centrifugal pump shaft bending. Bearing uneven force, but also lead to high bearing temperature. Approach is to straighten the pump shaft.
Direct Warping Machine
A-ZEN direct warping machine is a new-developed machine with advanced function. A brand new closed circuit tension technology, known as PID technology, is used on direct warping machine AZ118L type, and because of that, yarn tension stability and accuracy are both assured.
