Transportation field
1. Car (fuel vehicle)
Application scenarios:
Fuel supply system: The electric fuel pump (built-in or external) transports fuel from the fuel tank to the engine injector, providing stable pressure (such as gasoline engine 0.3-0.6MPa, diesel engine common rail system can reach more than 160MPa).
Lubrication system: The oil pump pressurizes the engine oil and transports it to various moving parts of the engine (such as crankshafts and camshafts) to lubricate, cool and clean.
Transmission system: The automatic transmission oil pump provides pressure to the hydraulic control system to achieve precise control of the gear shift actuator (clutch, brake).
Typical components:
Electric fuel pump (built-in fuel tank, silent and efficient);
Mechanical oil pump (driven by the engine crankshaft or camshaft, such as gear pumps, rotor pumps).
2. Motorcycle/tricycle
Application scenarios:
Carburetor model: Mechanical oil pumps (such as diaphragm pumps) are driven by negative engine pressure to send fuel from the fuel tank to the carburetor;
Electronic injection model: Small electric fuel pump provides fuel injection pressure and has a more compact structure.
3. Ship/Yacht
Application scenarios:
Diesel engine fuel supply: High-pressure oil pumps (such as plunger pumps) provide high-pressure fuel for marine diesel engines to meet high-power requirements;
Lubricating oil circulation: The oil pump ensures that the ship's engine is fully lubricated during long runs.
4. Aircraft (fuel aircraft)
Application scenarios:
Aviation fuel delivery: Electric oil pumps or gear pumps transport fuel from the wing fuel tank to the engine combustion chamber, which must meet the stability in high altitude and low pressure environments;
Hydraulic system: Some aircraft hydraulic systems use oil pumps to provide power to control flaps, landing gear and other components.

Industrial equipment field
1. Construction machinery (excavators, loaders, cranes, etc.)
Application scenarios:
Diesel engine fuel system: High-pressure oil pumps (such as electronically controlled single-body pumps) provide high-pressure fuel for construction machinery engines to adapt to heavy-load and high-load working conditions;
Hydraulic system: Hydraulic oil pump (gear pump, plunger pump) drives the hydraulic cylinder to realize excavation, lifting and other actions.
2. Power generation equipment (diesel generator set)
Application scenarios:
Fuel pumping: The oil pump transports diesel from the oil storage tank to the generator set engine to ensure continuous power generation;
Lubrication and cooling: The oil pump maintains the internal lubrication of the engine, and the cooling oil pump provides cooling fluid circulation power for the cooling system.
3. Machine tools/processing equipment
Application scenarios:
Cutting fluid supply: The oil pump pressurizes the cutting fluid and sprays it to the processing area to cool, lubricate and chip removal functions;
Rail lubrication: The micro-oil pump delivers lubricating oil to the machine tool guide rails regularly and regularly to reduce friction and wear.
4. Petrochemical industry
Application scenarios:
Crude oil delivery: Large oil transfer pumps are used for oil pipeline transportation, overcoming the resistance of long-distance transportation;
Chemical raw material pumping: Corrosion-resistant oil pumps (such as stainless steel gear pumps) are used to transport chemical liquids such as acids and alkalis.

Agriculture and Gardening Machinery
1. Agricultural machinery (tractors, harvesters, seeders, etc.)
Application scenarios:
Diesel engine oil supply: Mechanical oil pumps (such as distribution pumps) provide fuel to agricultural machinery engines to adapt to complex working conditions in the field;
Spray system: Liquid pump (centrifugal pump, plunger pump) Pressure the pesticide or fertilizer solution and spray it through the spray head.
2. Garden machinery (lawmower, sprayer)
Application scenarios:
Small engine oil supply: The diaphragm oil pump conveys mixed fuel (gasoline + oil) for a two-stroke engine;
Plant protection operation: Micro electric oil pump drives the sprayer to achieve precise application of medicine.
4. Aerospace and special scenarios
1. Aerospace propulsion system
Application scenarios:
Rocket engine: The turbo pump pressurizes propellants such as liquid oxygen and kerosene and injects them into the combustion chamber, generating huge thrust (such as the SpaceX Merlin engine uses a turbo pump);
Missile guidance system: The micro oil pump provides power to the hydraulic servo and controls the flight attitude.
2. Emergency and Special Vehicles
Application scenarios:
Fire truck / Firetruck: Fire pump (centrifugal pump) pumps water from the water source and pressurizes it to extinguish the fire by spraying the water gun;
Military vehicles: High-pressure oil pumps provide power to the hydraulic suspension system and weapon pitch mechanism of armored vehicles.
