The use of long axis pumps has increased our productivity and reduced the workload of our workers. However, in their work, the user is more concerned that in the work, the long-axis pump will have a fault occurs, then the common long axis pump fault what? Is there a fault solution? I believe these are all users want very much to understand the information. These questions will be analyzed next.
1, can not start up
Reason: Long shaft vibration can not vibrate due to motor or power supply system failure, there are foreign parts in the rotor, the bearing is stuck, starting conditions are not met.
The solution is to repair the motor or power supply system, clean rotor parts, clean or replace the bearings, check the conditions to be met lack of flow or no water.
2, lack of flow or no water
Reason: generally suction side or outlet side or clogged clogs, seal ring wear too much, impeller damage, steering is not, accommodation is too low, not enough depth of submergence, inhalation of air.
Solution: Clean the screen, impeller, guide vane body, exhaust pipe, valve system; replace damaged parts; correct steering; measure voltage, frequency, check the motor; increase suction water level.
3, long-axis pump abnormal vibration and noise
The solution: Need to improve the long-axis pump suction water level or off the gate valve, the impeller to adjust the static balance, the correction of the concentric shaft, than the straight shaft, tighten the anchor bolts, replace the bearing, guide bearing replacement.
Long axis pump is used to transport clean water and contains some solid particles of sewage, with corrosive industrial waste water and other harsh material equipment, it is in sewage treatment, primary water treatment, metallurgical steel industry, mining, power plants, municipal engineering, irrigation and other farmland Areas play an important role. It is believed that long axis pump failure problems can have a significant impact on long axis pump usage and accelerating the study of these failures will have a very positive effect on the future of long axis pumps.
