Screw pump It is a centrifugal pump widely used in the industrial field. Common faults will affect the normal operation of the pump and may lead to production interruption. Therefore, it is very important to identify and solve these faults in time. The following are the common faults of the screw pump.

Bearing fault: bearing fault is one of the common faults of screw pump. As the screw pump bears a lot of pressure and friction when working, the bearing is easily damaged. Typical manifestations of bearing failure include increased noise, temperature rise, vibration and reduced pump efficiency. Bearing failure may be caused by poor lubrication, impurities entering the bearing or bearing wear.

Leakage fault: IMO screw pump Leakage may occur during operation. Leaks often occur at seals, connections, or pump volumes. Pump leakage may be caused by aging, damage or improper installation of seals. Leakage will not only lead to energy waste, but also may cause environmental pollution and even accidents. IMO agent

Shaft seal failure: the shaft seal is a key component of the screw pump, which is mainly used to prevent the medium in the pump from leaking to the outside. The failure of shaft seal will lead to the decline of pump efficiency, pressure loss, shortening of pump life and other problems. The shaft seal failure may be caused by impurity intrusion, high operating temperature, bearing failure, etc.

Failure of inlet and outlet valves: the inlet and outlet valves of the screw pump are the key components to control the fluid inlet and outlet, and failure will affect the normal operation of the pump. Common faults include valve blockage, untight closing, leakage, etc. These failures may be caused by valve wear, scaling, impurities entering, etc.

Overload fault: when the screw pump is working, various factors (such as medium viscosity change, improper adjustment of pump speed, etc.) may lead to overload of the pump. Overload will increase the load of the pump, reduce the efficiency of the pump, and even cause damage to the pump. Therefore, it is very important to check the working state of the pump in time to avoid overload. ALLWEILER

Screw fracture or wear: screw may be fractured or worn due to the large pressure and friction force that the screw pump bears during a long time of operation. Screw fracture will lead to the shutdown of the pump, and wear will lead to the decline of pump efficiency.

Motor fault: the work of the screw pump needs the motor to provide power. If the motor fails, the normal operation of the pump will be seriously affected. Common motor faults include motor overheating, motor starting difficulty, abnormal noise, etc.

Excessive temperature rise: when the screw pump is working, the temperature rise of the pump may be too high due to the high viscosity of the medium and the large friction force in the pump. Too high temperature rise will not only lead to the decline of pump performance, but also may lead to pump blockage, bearing failure and other problems. ALLWEILER screw pump

The above are common faults of screw pump. Timely finding and solving these faults is the key to ensure the normal operation of screw pump. Pay attention to regular inspection and maintenance during daily maintenance to ensure the normal operation of screw pump and improve production efficiency.
