IMO screw pump Is a commonly used centrifugal pump, widely used in industry, construction, agriculture and other fields. During use, Screw pump Various faults may occur, such as water leakage, vibration, noise, etc. The following are some common problems in screw pump fault diagnosis and solutions:
Water leakage of pump body: water leakage of pump body is one of the most common faults of screw pump. Possible causes include aging of seals, wear, looseness or damage of seal rings, etc. The solution includes replacing the seals or sealing rings and ensuring that the fastening bolts are correctly installed.
Bending or wear of pump shaft: The pump shaft of screw pump may be bent or worn due to overload, imbalance or vibration. The solution includes regularly checking and adjusting the alignment of the pump shaft, avoiding overload operation, and replacing the pump shaft if necessary. ALLWEILER
Excessive clearance between pump shaft and shaft sleeve: excessive clearance between pump shaft and shaft sleeve may cause leakage and energy loss. The solution includes checking and adjusting the shaft sleeve clearance to ensure that it is within the allowable range.
Abnormal noise of pump motor: abnormal noise of screw pump motor may be caused by bearing damage, loose internal parts of motor, wear of mechanical parts, etc. Solutions include replacing bearings, inspecting and fastening loose parts, and regularly maintaining and lubricating mechanical components.
Pump vibration: screw pump vibration may be caused by imbalance, bearing damage, foundation instability and other reasons. The solution includes checking and balancing the rotor, replacing the bearing, ensuring the stability of the pump foundation, and eliminating possible external force interference. IMO agent
Jamming of foreign matters inside the pump: Jamming of foreign matters inside the pump may lead to difficult operation of the pump rotor and mechanical wear. The solution includes regular cleaning and inspection of the inside of the pump to ensure that there is no foreign matter and to avoid foreign matter input. ALLWEILER screw pump
The pump temperature is too high: the high temperature of the screw pump may be caused by overload, excessive friction heat, poor lubrication and other reasons. The solutions include avoiding overload operation, improving lubrication effect, and regularly checking and changing lubricating oil.
Abnormal pump outlet pressure: The abnormal outlet pressure of the screw pump may be caused by insufficient opening of the inlet valve, untight closing or blockage of the exhaust valve, etc. The solution includes checking and adjusting the valve opening, cleaning or replacing the blocked parts, and ensuring that the exhaust valve is closed normally.

Reduction of pump flow: The reduction of screw pump flow may be caused by the blockage of inlet pipeline, internal wear of pump or abnormal regulating valve. The solution includes cleaning the inlet pipeline, inspecting and replacing worn parts, and ensuring the normal operation of the regulating valve.
Difficulty in starting the pump: The difficulty in starting the screw pump may be caused by motor failure, unstable power supply or abnormal control system. Solutions include checking and replacing faulty motors, ensuring a stable power supply, and repairing or replacing faulty parts of the control system.
To sum up, the fault diagnosis and solutions of screw pump cover many aspects, such as pump body leakage, pump shaft bending or wear, excessive clearance between pump shaft and shaft sleeve, abnormal noise of pump motor, pump vibration, blockage of foreign matters inside the pump, high pump temperature, abnormal pump outlet pressure, reduced pump flow and difficulty in starting the pump. In actual use, users should regularly check and maintain the screw pump to ensure its normal operation and extend its service life.
