The types of diesel engine water pumps and several factors that affect the efficiency of the clean water pump
Self-priming water pump: The water quality is good, the working position is relatively fixed, the suction distance is less than 3.Self-priming water pump: The water quality is good, the working position is relatively fixed, the suction distance is less than 3.5 meters, and the pipeline is stable.5 meters, and the pipeline is stable. When it is used for well water supply and orchard irrigation, it can reduce the trouble of irrigation. When it is used for well water supply and orchard irrigation, it can reduce the trouble of irrigation. The actual head is less than 22 meters, and the efficiency of the chemical pump is slightly lower. The actual lift is less than 22 meters. The efficiency of the chemical pump is slightly lower. When the pump is first put into operation, it is necessary to first add circulating drainage, and then the pump can be self-priming.
2. During the first operation of the pump, it is necessary to first add circulating drainage before the pump can complete its self-priming.
2. Clean water pump filled with water: The water quality is relatively constant and the main pipeline is relatively stable. The actual lift force within a suction distance of 2.5 meters is within 32 meters. Clean water pump filled with water: The water quality is relatively flowing, and the main pipeline is relatively unstable. The actual lift force within a suction distance of 2. The pump flow rate can be adjusted as needed and can be adapted for spraying pesticides and irrigation by planting and fruit professionals. The water supply is efficient.5 meters is within 32 meters. The suction pipe should be sealed well.
3. The pump flow rate can be adjusted as needed, and it can be adapted for use by planting and fruit professionals for spraying pesticides and irrigation. The water supply is efficient. Submersible Water Pump: With abundant water supply and low water head, it is suitable for large-scale irrigation in farmlands and orchards. The suction pipe should be sealed well.
3. Since the submersible pump is placed in water, the water flows axially along the shaft, which increases the load on the pump when the output decreases. Submersible Water Pump: With abundant water supply and low water head, it is suitable for large-scale irrigation in farmlands and orchards. Therefore, do not install the valve on the drainage pipe of the submersible pump to prevent the motor from burning out due to valve closure, which would cause excessive resistance on the pump.
Since the submersible pump is placed in water, the water flows axially along the shaft, which increases the load on the pump when the output decreases.Several factors that affect the efficiency of the cleaning pump:
The efficiency of the cleaning pump itself is the most fundamental factor that affects the outcome. Therefore, do not install the valve on the drainage pipe of the submersible pump to prevent the motor from burning out due to valve closure, which would cause excessive resistance on the pump. For pumps operating under the same conditions, the efficiency can vary by more than 15%.

2.Several factors that affect the efficiency of the cleaning pump:
The operating conditions of the water pumps are all below the rated conditions of the pumps, resulting in low pump efficiency and high energy consumption.
3.The efficiency of the cleaning pump itself is the most fundamental factor that affects the outcome. The efficiency of the motor remains relatively stable in practical applications. Therefore, it is crucial to select an efficient motor.
For pumps operating under the same conditions, the efficiency can vary by more than 15%.4.
2. The impact on the efficiency of the cleaning pump is mainly related to the quality of design and manufacturing. The operating conditions of the water pumps are all below the rated conditions of the pumps, resulting in low pump efficiency and high energy consumption.
3. After selecting the pump, the influence of subsequent management is relatively insignificant.
5. The efficiency of the motor remains largely unchanged in practical applications. Hydraulic losses include hydraulic friction loss and local resistance loss. Therefore, it is crucial to select an efficient motor.
4. The impact on the efficiency of the cleaning pump is mainly related to the quality of design and manufacturing. After a period of operation, the surfaces of the impeller and guide vanes will inevitably wear out, resulting in an increase in hydraulic losses and a decrease in hydraulic efficiency.
6. After selecting the pump, the influence of subsequent management is relatively insignificant.
5. Hydraulic losses include hydraulic friction loss and local resistance loss. The volume loss of the diesel engine water pump is also known as leakage loss, which includes three types of leakage losses from the impeller sealing ring, the inter-stage and axial force balance mechanism. After a period of operation, the surfaces of the impeller and guide vanes will inevitably wear out, resulting in an increase in hydraulic losses and a decrease in hydraulic efficiency.
6. The volumetric efficiency is not only related to design and manufacturing, but also to post-operation management. After the pump operates continuously for a period of time, due to the friction between components, the gap increases and the volumetric efficiency decreases.
7. The volume loss of the diesel engine water pump is also known as leakage loss, which includes three types of leakage losses from the impeller sealing ring, the inter-stage and axial force balance mechanism. Due to the blockage of the filter cylinder and the inlet of the pipeline, the centrifugal pump is running empty.
The volumetric efficiency is not only related to design and manufacturing, but also to post-operation management.8. Before the pump was started, the employees failed to pay attention to the preparatory work for the centrifugal pump. After the pump operates continuously for a period of time, due to the friction between components, the gap increases and the volumetric efficiency decreases.
7. Due to the blockage of the filter cylinder and the inlet of the pipeline, the centrifugal pump is running empty.
8. Basic operation procedures such as warming the pump, rotating it, and filling it with liquid were not fully carried out, which often led to air erosion of the pump, resulting in high noise, significant vibration, and low pump efficiency.
