What are the components of the hydraulic system of the forklift?

Pump – The one that pumps the oil out and supplies it to other hydraulic components.

Multi-way valve - transfer the pumped oil to the mast system, tilting cylinder, steering system.

Steering Gear – Distribute the oil from the multi-way valve to the steering mechanism.

Lifting cylinder - jacking the gantry, the oil comes from the multi-way valve.

Steering cylinder (also known as transverse cylinder) - oil comes from the steering gear and controls the steering of the rear wheels.

Attachments – the oil comes from a multi-way valve that controls special operations such as sideways, rotated, and tipped.

Hello, the hydraulic system of the forklift has the following components. Pump: Pumps out the oil and supplies it to other hydraulic components.

Multi-way valve: Pump the oil to the mast system, tilt cylinder, steering system. Steering gear:

The oil from the multi-way valve is distributed to the steering mechanism. Lifting cylinder: jacking the mast frame.

Steering cylinder: also known as transverse cylinder. The oil comes from the steering gear, which controls the rear-wheel steering.

Attachments – the oil comes from a multi-way valve that controls special operations such as sideways, rotated, and tipped. Hope it helps you and good luck.

It is composed of oil pump, multi-way reversing valve, steering gear, shut-off valve, oil cylinder and new divert speed limiting valve.

hydraulic steering of the rear wheels; The wishbone is tilted up and down, left and right, and back and forth. Give me some points, man!!

The working principle of the hydraulic system of the forklift mainly includes the following parts:

1. The working principle of the power mechanism: the oil pump is used to transfer the mechanical energy to the liquid, so that the liquid sealed in the container produces hydraulic energy.

2. The working principle of the actuator: including the oil motor or oil cylinder. Their function is the opposite of that of an oil pump, which converts the pressure energy of the liquid into mechanical energy, so that the working device produces rotational motion or linear displacement.

3. The working principle of the control element: including various operating valves, such as directional control valves, throttle valves, relief valves and other components, through which the pressure, flow and direction of the liquid are controlled and mediated to meet the requirements of the working performance of the mechanism.

4. The working principle of auxiliary components: including oil tank, oil pipe, oil joint, oil filter, etc. Through these elements, the above three parts can be connected into a system to form a hydraulic device.

The hydraulic device of the forklift has the following points:

Power Component - Oil Pump.

Cylinders. - At present, most of the forklifts use piston cylinders.

Hydraulic valves - the commonly used valves on forklifts are diverter valves (most of them are single-way stable diverter valves), one-way throttle valves, and relief valves.

multi-way directional valves, etc.

Auxiliary devices – oil tanks, tubing, fittings, oil filters, etc.

gantry systems (lifting systems); transmission system (gearbox); travel system (drive axle); powertrain (engine); steering system (transverse cylinders, steering horns, etc.); body systems (body frames, roof guards, etc.); In addition, there are circuit systems (vehicle line instrument panels) and hydraulic systems (hydraulic pumps, pipelines, cylinders, control valves, etc.), which are roughly divided into so many.

Internal combustion forklifts are generally composed of three parts: power unit, chassis and working device.

Power plant of forklift: power system, electrical system.

Forklift chassis: transmission system, walking system, steering system, braking system.

Forklift working device: mast system, hydraulic system, attachment system.

When the brake pedal is pressed, the brake fluid pressed out from the brake master cylinder enters the auxiliary pump first, and the hydraulic oil is passed into the front and rear brake cylinders from this part, and the other part acts on the control valve, so that the vacuum afterburner air chamber is pressed on the piston of the auxiliary pump, so that the pressure of the auxiliary pump and the wheel brake fluid becomes much higher than that of the master cylinder, thus increasing the braking force of the electric stacker.

When the vacuum level of the engine intake pipe is higher than that of the vacuum cartridge, the vacuum check valve opens; When the engine stops, the check valve closes. In this way, it can ensure that the vacuum cartridge and the vacuum afterburner chamber have a high vacuum degree.

The hydraulic system of the forklift is to provide hydraulic oil through a gear pump, the pressure is generally 20MPa, and the hydraulic oil passes through a multi-way control valve to control the lifting and tilting action of the mast. Generally, there is a priority valve in the control valve of the internal combustion forklift, and the hydraulic oil is preferentially supplied to the steering gear when the vehicle is steering, and the steering axle is controlled. When the vehicle is not moving, the hydraulic oil is discharged directly to the fuel tank through the multi-way valve.

It's very simple, find a forklift, and follow the oil road by yourself to understand everything.

1. The working principle of manual hydraulic forklift: the principle of hydraulic transmission, using oil as the working medium, transmitting movement through the change of sealing volume, and transmitting power through the pressure inside the oil.

Second, the internal structure of the manual hydraulic forklift:

1. The power part converts the mechanical energy of the prime mover into the pressure energy (hydraulic energy) of the oil. For example: hydraulic pumps.

2. The execution part converts the oil pressure energy input from the hydraulic pump into the mechanical energy of the driving mechanism. For example: hydraulic cylinders, hydraulic motors.

3. The control part is used to control and adjust the pressure, flow and flow direction of the oil. Examples: pressure control valves, flow control valves, and directional control valves.

4. The auxiliary part connects the first three parts together to form a system, which plays the role of oil storage, filtration, measurement and sealing. For example: pipes and fittings, fuel tanks, filters, accumulators, seals and control instruments.

In fact, it's the same principle as a pump, a piston rod, two check valves, a spring, one end to the cylinder, one end to the tank.
