What pump is used for sprinkler irrigation machine?
As the core equipment of efficient irrigation in modern agriculture, the performance of the sprinkler irrigation system is closely related to the selection of water pumps. This article combines the hot agricultural technology topics on the Internet in the past 10 days to sort out the key points for selecting sprinkler pumps, comparison of mainstream products, and analysis of usage scenarios to help users accurately match their needs.
1. Commonly used water pump types and characteristics of sprinkler irrigation machines
| Pump type | Working principle | Lift range | Flow range | Applicable scenarios |
|---|---|---|---|---|
| centrifugal pump | The rotation of the impeller generates centrifugal force | 10-200 meters | 5-1000m³/h | Large area irrigation in plains |
| submersible pump | The motor and pump body are integrated into the water | 5-150 meters | 3-500m³/h | Deep well/reservoir water intake |
| self-priming pump | Automatically evacuates gas to create a vacuum | 8-80 meters | 1-200m³/h | Mobile sprinkler system |
| pipeline pump | Low head and large flow design | 5-30 meters | 10-2000m³/h | Pipe network pressurization system |
2. Performance comparison of mainstream sprinkler pumps in 2023
| Brand model | Power(kW) | Maximum lift (m) | Rated flow (m³/h) | Price range (yuan) |
|---|---|---|---|---|
| Grundfos CRN3-7 | 3.0 | 52 | 7.2 | 5800-7200 |
| Wilo MVI1602 | 1.6 | 35 | 4.5 | 3200-4500 |
| New Territories 100GDL24 | 5.5 | 80 | twenty four | 4200-5500 |
| Kaiquan ISG65-160 | 7.5 | 32 | 50 | 6800-8500 |
3. Calculation Guide for Core Parameters of Pump Selection
1.Traffic demand= Number of nozzles × flow rate of a single nozzle × safety factor (1.1-1.3)
2.Lift calculation= Terrain height difference + Pipe loss + Nozzle working pressure
3.Power matching= (Flow rate × head × 9.8) ÷ (3600 × pump efficiency × 0.85)
4. Top 5 recent hot issues
| Ranking | question | solution |
|---|---|---|
| 1 | The water pump is damaged due to frequent starts and stops. | Install pressure tank/frequency controller |
| 2 | Pump efficiency decreases in plateau areas | Choose a plateau-resistant model with a power margin of 20% |
| 3 | Serious wear and tear in sandy water | Switch to wear-resistant material impeller + pre-filter |
| 4 | Electricity costs are too high | Replace IE4 energy efficiency motor + solar complementary |
| 5 | Winter frost cracking risk | Install electric heating tape + exhaust device |
5. Latest technology trends
1.Intelligent frequency conversion technology: Automatically adjust the speed according to soil moisture, saving more than 30% energy
2.IoT remote monitoring: View flow, pressure, and energy consumption data in real time through the APP
3.Composite material applications: Carbon fiber impeller reduces weight by 40% and extends life by 3 times
4.Photovoltaic direct drive system: Solar panels directly drive the water pump, eliminating the need for batteries.
6. Purchase suggestions
1. For small plots (<5 acres), self-priming pumps are preferred, as they are easy to move and require no irrigation or water diversion.
2. Choose a multi-stage centrifugal pump in hilly areas to ensure sufficient head.
3. Large-scale farms are recommended to configure a pipeline pump + pressure tank combination system
4. Pay attention to the NPSH parameters of the pump to avoid cavitation damage.
According to the latest data from the Ministry of Agriculture and Rural Affairs, reasonable pump selection can increase the energy efficiency of sprinkler irrigation systems by more than 25%. It is recommended that users do field measurements and calculations before purchasing, and consult professional irrigation engineers for system design when necessary.
