The internal structure of a manual hydraulic forklift (DiNiu) is mainly divided into a power part, an execution part, a control part, and an auxiliary part, which work together to achieve the functions of lifting and transporting goods. Here is a detailed introduction:

1、 Power section

Hydraulic pump: As the source of power, manual hydraulic forklifts usually use manually operated plunger pumps or gear pumps. When the staff holds the handle and performs up and down reciprocating motion, the plunger or gear inside the pump operates accordingly, converting mechanical energy into hydraulic energy and providing power to the hydraulic system.

2、 Execution section

Hydraulic cylinder: The hydraulic cylinder is a key executing component for forklift operations. When the high-pressure oil output by the hydraulic pump is injected into the hydraulic cylinder, the pressure of the oil pushes the piston to make linear motion in the cylinder, converting hydraulic energy into mechanical energy. The fork connected to the piston will rise or fall with the movement of the piston, thus completing the lifting and lowering actions of the cargo.

3、 Control section

Pressure control valve: used to regulate the working pressure of the hydraulic system, ensuring that the system operates within a safe range.

Flow control valve: Based on actual work requirements, the flow rate of the oil is reasonably controlled to regulate the lifting speed of the fork.

Directional control valve: determines the direction of oil flow, thereby controlling the upward, downward, and static state of the fork.

4、 Auxiliary section

Pipelines and fittings: Accurately deliver hydraulic oil to various required parts to ensure the normal operation of the system.

Oil tank: As an energy storage reservoir, it reserves sufficient hydraulic oil for the entire system.

Filter: constantly filters out impurities and pollutants in the oil, ensuring the cleanliness of the oil and allowing the system to operate smoothly, avoiding component wear or failure caused by impurities.

Accumulator: absorbs pressure fluctuations to ensure stable operation of the system.

Seals: Ensure the sealing of the hydraulic system to prevent oil leakage.

Control instrument: used to monitor and display various parameters of the hydraulic system, such as pressure, flow rate, etc., to facilitate operators to timely understand the system status.
