Some Hydraulic Parts on Construction Machinery

There are very many hydraulic parts in every construction machinery, and this article briefly introduces two common hydraulic parts.

Hydraulic Cylinder

The hydraulic cylinder is the main hydraulic component in the hydraulic device of construction machinery to complete the actual operation. A hydraulic bucket cylinder is an important basic component indispensable in hydraulic excavators or other construction machinery.

What is a Hydraulic Cylinder

A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or oscillating motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating motion, it can eliminate the deceleration device, and there is no transmission gap, and smooth movement, so it is widely used in the hydraulic system of various engineering machinery and equipment. The output force of a hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between its two sides; the hydraulic cylinder basically consists of a cylinder barrel and cylinder head, piston and piston rod, sealing device, cushioning device, and exhaust device.

How Does a Hydraulic Cylinder Work

Hydraulic cylinder has 5 basic parts: 1. cylinder barrel and cylinder head 2. piston and piston cylinder 3. sealing device 4. cushioning device 5. exhaust devise. The working principle of each type of hydraulic cylinder is almost similar. Take the simplest cylinder jack as an example. The manual booster lever so that the hydraulic oil through a one-way valve into the cylinder, the hydraulic oil into the cylinder because of the one-way valve can not return, forcing the cylinder rod up to make the jack rise, to fall when you open the hydraulic valve, this is the simplest working principle of the hydraulic cylinder. The others are improved on the basis of this.

Hydraulic Motor

The weight of medium and large construction machinery generally weighs tens of tons. The machine's inertia is very large, so in the process of starting and stopping the machine will bring a relatively large impact on the hydraulic system, so the travel control system must be improved to adapt to such conditions. The characteristics of the hydraulic motor are suitable for this.

What is a Hydraulic Motor

The hydraulic motor is an actuating element of the hydraulic system, which transforms the liquid pressure energy provided by the hydraulic pump into the mechanical energy (torque and speed) of its output shaft. The fluid is the medium for transmitting force and motion. A hydraulic motor, also known as an oil motor, is widely used in construction machinery. MyMRO is a good online store that has the hydraulic motor for sale.

How Does a Hydraulic Motor Work

Hydraulic pump is the source of the power of construction machinery. The hydraulic pump is the source of power that converts the mechanical energy generated by the engine into hydraulic energy. Hydraulic oil is the power transmission medium, and hydrauli motor is the execution element, and the hydraulic energy into mechanical energy. The hydraulic pump is unidirectional rotating and flow adjustable. And walking motor is a two-way rotation of two-stage speed regulation. The hydraulic pump is the mechanical energy of the engine into hydraulic energy to achieve the linear motion of the hydraulic cylinder piston rod power parts, and the motor is the pump output of hydraulic energy and into mechanical energy to drive the excavator walking. Pump and motor structure is similar, but the opposite use.
