Core features of DC submersible pumps
Wide voltage range: Common voltages include 12V, 24V, 48V, 60V, etc., making it suitable for DC power sources such as electric bicycles, solar panels, and vehicle-mounted batteries.
Smart control: Supports PWM speed regulation and analog signal input for speed adjustment; customizable features include music fountains and flow rate control.

The working principle of a DC submersible pump
A DC submersible pump drives an impeller to rotate via a DC motor. Utilizing centrifugal force, the pump propels liquid (such as water) from the center of the impeller outward. As the liquid flows within the pump casing, its velocity gradually decreases and its pressure increases, eventually being discharged through the outlet.

Testing methods for silicone tubes
Physical and Mechanical Property Testing: such as density, hardness, tensile strength, elongation, etc.
Electrical Property Testing: such as surface resistivity, dielectric properties, etc.
Main application scenarios of oil pumps
Automotive applications: Oil pump (for lubricating the crankshaft, camshaft, etc.), low-pressure fuel pump (from fuel tank to fuel lines), high-pressure direct-injection fuel pump (injects fuel directly into the cylinders at 150–300 bar), and diesel high-pressure injection pump.

The core working principle of an oil pump
The moving parts (gears, vanes, plungers) and the pump housing form a sealed cavity whose volume varies periodically.
When the cavity volume increases, a negative pressure is created, drawing oil fluid into the pump from the suction port.
