How a Tractor Hydraulic Pump Works?
The tractor hydraulic pump is an important component of the hydraulic system, providing power for various mechanical functions, such as steering, lifting, braking, and operating accessories. Its working principle is to convert the mechanical energy of the tractor engine into hydraulic energy, and then use it to drive different systems. The operation of a gear pump is based on the movement and displacement of hydraulic oil through precisely designed gears.
This tractor hydraulic gear pump is usually composed of two meshing gears, which are installed inside a metal casing. One of the gears is connected to the tractor's engine or power output (PTO) system, which drives the gears to rotate. When the gears rotate, they create a vacuum at the pump's inlet, drawing hydraulic oil (usually oil) from the oil tank into the pump. Then, the oil is trapped between the gear teeth and the wall of the pump casing.
As the gears continue to rotate, the hydraulic oil is delivered from the inlet side of the hydraulic pump to the outlet side. The meshing of the gears at the outlet forces the oil to flow out of the pump under high pressure. Then, these pressurized fluids are conveyed through hydraulic pipelines to various systems, such as lifting equipment or operating steering mechanisms.
This hydraulic pump for tractor operates continuously when the tractor is running, ensuring a stable supply of hydraulic oil and thus maintaining the system's functionality. Its simple yet sturdy design makes it efficient, durable and reliable in agricultural applications.
