Diesel engine water pump unit is a kind of water pump equipment powered by diesel engine, which is widely used in fire protection, agricultural irrigation, emergency drainage and other fields. How to use a Diesel engine water pump unit. I hope the following introduction can bring reference to users.
1. Preparation before starting the Diesel engine water pump unit
Fuel & Lubricant Inspection
Ensure that the oil volume of the diesel fuel tank is sufficient, the oil level of the oil pan is within the calibration range, and the governor oil needs to be replenished to the specified value.
Check the cooling tank level, it is recommended to use clean fresh water or demineralized water.
Device status confirmation
Place the Diesel engine water pump unit on a stable ground and check whether the inlet pipe and the outlet pipe are tightly connected to avoid air leakage.
Make sure that the water inlet pipe is a rigid steel wire pipe and is firmly connected to prevent the water suction pipe from collapsing due to negative pressure.
2. Start and run the diesel engine pump
Diesel engine water pump start operation
Switch the control switch to "Manual" or "Auto" mode, press the start button, and the diesel engine gradually accelerates to the rated speed.
Observe the dashboard parameters (e.g., speed, pressure) to ensure that there is no abnormal noise or vibration.
Self-priming and delivery
The impeller rotates to create negative pressure, and the liquid is drawn into the pump chamber through the inlet pipe, and the self-priming process takes a few seconds to a few minutes (depending on the model and liquid characteristics).
During normal operation, the liquid is discharged through the outlet pipe, and the flow can be controlled by adjusting the speed of the diesel engine.
3. Diesel engine water pump unit shutdown and maintenance
Downtime steps
Reduce the load first, turn off the Diesel engine water pump unit, and cut off the power supply after the complete shutdown.
It is recommended to install a check valve for the outlet pipeline to prevent liquid backflow
Diesel engine water pump unit routine maintenance
Change the oil regularly, clean the filter, and check for seal wear.
Long-term storage needs to drain the water in the pump to prevent rust of parts.
4. Precautions for Diesel engine water pump unit
Suction range limit: The nominal suction distance of self-priming pumps is usually 6-7 meters, and it is recommended to control it within 4 meters to avoid the risk of cavitation.
Load monitoring: avoid overload operation, regularly check the engine temperature and diesel engine pump pressure.
Also pay attention to the daily inspection in the process of using the Diesel engine water pump unit, check the oil, fuel and coolant level, seal status, etc.I hope the above introduction can bring reference to users.
