A diesel engine pump is an electromechanical device powered by a diesel engine and directly drives a water pump through an elastic coupling. It is widely used in fire fighting, emergency drainage, agricultural irrigation, industrial water supply, and other fields.
I. Characteristics of Diesel Engine Pumps
Diesel engine pumps feature strong power, quick start-up, strong self-priming ability, and stable and reliable operation. They also integrate intelligent control and multiple protection functions, making them suitable for scenarios without power supply or for mobile operations, such as firefighting, emergency drainage, and agricultural irrigation.

III. Advantages of Diesel Engine Pumps
1. Diesel engine pumps start quickly and are highly reliable, making them suitable for emergency situations such as firefighting, drainage, and emergency water supply.
2. Diesel engine pumps have strong power and high flow and head capacity, meeting the needs for large volume, high-head water discharge or supply.
3. Diesel engine pumps do not require an external power source and have their own power, allowing stable operation during power outages, in remote areas, or in emergency scenarios.
4. They have a wide range of applications and are resistant to harsh environments, making them suitable for use in construction sites, mines, municipal projects, flood control, oil fields, and other settings.
5. Maintenance and use are flexible; fuel supply is convenient, mobility is easy, and they can operate continuously for long periods.
IV. Precautions for Using Diesel Engine Pumps
1. Pre-start Checks for Diesel Engine Pumps: Ensure sufficient fuel, oil level is up to the upper mark, and the cooling water tank is full; check fasteners and instrument wiring; flush the filter screen to prevent clogging; check that the battery terminals are clean to prevent oxidation; verify the model and specifications, select the correct gasket, and tighten bolts.
2. Operation Monitoring of Diesel Engine Pumps: Preheat before starting and gradually increase load; monitor instruments; ensure normal bearing temperature; packing leaks should be 15-30 drops per minute; listen for abnormal noises and vibrations; use clean diesel and maintain filters regularly; avoid overloading at low head.
3. Shutdown and Maintenance of Diesel Engine Pumps: Gradually unload before shutting down; close fuel and cooling water valves; in cold weather, drain the cooling system and any water in the pump to prevent freezing and cracking; regularly clean or replace the coarse filter of the fuel pump; press back the manual oil pump button after use; ensure the fuel pump’s "four springs" maintain elasticity and that sealing gaskets are intact; keep the pump body’s drain holes unobstructed; check and add governor oil daily.
4. Long-term Storage of Diesel Engine Pumps: Drain all remaining water and clean the internal and external systems; fill the fuel injection pump channels with diesel, and apply anti-rust oil after disassembly for dry storage; perform maintenance according to manufacturer schedules, replacing seals, filters, and lubricants; disassembly and adjustment of precision components should be carried out by professionals.
V. Questions and Answers on Diesel Engine Pumps
1. What preparations should be made before long-term storage of a diesel engine pump?
All oil and water should be drained, both the interior and exterior should be cleaned, and key metal parts should be coated with anti-rust oil.
2. What key areas should be checked before starting a diesel engine pump?
Check that the base, pipelines, and wiring are secure and leak-free, and flush the inlet and outlet strainers.
3. Which main instruments should be monitored during the operation of a diesel engine pump?
Closely monitor the oil pressure gauge, cooling water temperature gauge, and tachometer.
VI. Applications of Diesel Engine Pumps
1. Emergency Drainage: Diesel engine pumps can be rapidly deployed for emergency drainage during floods, heavy rain, or other natural disasters that cause urban waterlogging.
2. Industrial Water Supply and Drainage: Diesel engine pumps provide water for industrial production processes or are used to remove accumulated water and wastewater at construction sites.
3. Agricultural Irrigation: In areas with insufficient electricity or no power grid, they can be used to draw groundwater, river water, etc., for farmland irrigation.
4. Firefighting Systems: As fixed firefighting equipment or backup main pumps, diesel engine pumps can automatically start to provide a reliable water source and pressure for firefighting systems.
5. Petrochemical and Construction Engineering: They are used to transport process water, cooling water, or to address water accumulation issues at construction sites.
6. Post-Disaster Rescue: During post-disaster recovery, diesel engine pumps are used to remove accumulated water and clear drainage systems.
7. Water Supply in Special Situations: They can be used for industrial emergency purposes such as boiler feed water or high-temperature water supply, as well as in situations with special water supply requirements.
With powerful output, high reliability, and adaptability to environments without power or harsh conditions, diesel engine pumps are widely used in multiple critical areas. Users should choose the appropriate diesel engine pump based on specific work needs.
