2025-07-24

DGP self-balancing multi-stage boiler feed water pumps may experience interruptions during pumping, which can negatively impact the normal operation of the boiler. The following are the main causes of pumping interruptions.

I. Pump-related causes

1. Blade damage or blockage: Damage or blockage of the blades can reduce pump efficiency and potentially cause pumping interruptions.

2. Seal wear: Seal wear can cause internal leakage in the pump, affecting its normal pumping operation.

3. Bearing wear: Bearing wear can cause unstable pump rotation, affecting the pumping process.

II. Water source issues

1. Water source depletion: When the water source is depleted, the pump cannot draw enough water, leading to pumping interruptions.

2. Water level too low: If the water level is too low, the pump may not be able to draw water, also causing pumping interruptions.

III. Piping system issues

1. Pipe blockage: Impurities or sediment in the pipes can cause blockages, affecting water flow.

2. Pipe leakage: Pipe leakage leads to water loss and may affect the pump's pumping process.

IV. Electrical control system issues

1. Motor failure: Motor failure can prevent the pump from working normally, causing pumping interruptions.

2. Control system malfunction: A malfunctioning control system can prevent the pump from operating according to the set program, affecting the pumping process.

V. Operation and maintenance issues

1. Improper operation: Improper operation by personnel can cause abnormal pump operation, leading to pumping interruptions.

2. Insufficient maintenance: Lack of regular maintenance can lead to decreased pump performance and increase the risk of pumping interruptions.

VI. Other factors

1. Ambient temperature: Extreme ambient temperatures can affect pump performance and may cause pumping interruptions.

2. Voltage fluctuations: Unstable voltage can cause abnormal motor operation, affecting the pumping process.

In summary, interruptions in the pumping of DGP self-balancing multi-stage boiler feed water pumps can involve multiple factors, including the pump itself, the water source, the piping system, the electrical control system, and operation and maintenance. In actual operation, troubleshooting and handling should be based on the specific situation to ensure the normal operation of the boiler feed water pump.
