Anatomy of hydraulic cylinders

Anatomy of hydraulic cylinder hydraulic cylinder is 1 device that converts the energy from the pump into , for many technical and professional know about the hydraulic cylinder ( called ben south Hydraulic ) . However, there are also a lot of confusion when people encounter design , choosing a hydraulic cylinder suitable for your requirements .

Most of us who are familiar and seemed to know a lot about hydraulic cylinder ( in the south you called hydraulic ben ) . However, there are also a lot of confusion when people encounter design , choosing a hydraulic cylinder suitable for your requirements .

The first is the concept , called parts of the hydraulic cylinder . The following figure captions name some parts of a hydraulic cylinder .

Name :

- Barrel : Cylinder Shell

- Piston : Piston Fruit

- Cylinder rod : cylinder Officer

- Gland : Stock cylinder

- Pin eye / Clevis : Tai assembly

- Ports : Sugar , Oil on / off cylinder

- Piston Seal , Rod Seal , Wear ring , O -ring ; Wiper ... : The gasket seals

The working parameters and size of cylinder

3 The most important parameters of a hydraulic cylinder : cylinder diameter crush ( bore ) , usually denoted by D ; rolling diameter ( rod ) - d and stroke work ( stroke ) , or about running of the rolling cylinder , - s .

D and d denote the size and ability to push / pull the cylinder

S denotes the length and reach , range of cylinders that work .

Classification of hydraulic cylinders

The hydraulic cylinders are often divided into two basic groups : the impact cylinders ( one way) or two side effects Cylinders ( cylinder two -way ) .

Gu - hollow cylinder transplantation :

This type of cylinder is fitted and fixed by 4 gu - empty bar high tensile steel throughout lace lock to keep the two parts from the cylinder head cover (with the large-diameter cylinders can have up to 20 bar gu - empty hold ) . This structure helps shape cylinder removable , service cylinders are easy and also easy to make from standard parts . Cylinders of this type are often used in industrial applications .

Cylinders DC

Cylinders only one way to create a side thrust , the market usually needs cylinder , hydraulic oil through pressure on the rear cylinder . Officials in the cylinder itself by exerting a force of repulsion external or internal springs . It is most recognizable for its cylinders in a way that only an oil store .

Two -dimensional cylinder

Two -dimensional cylinder can generate power on both sides : When rolling cylinders sticking out and when it retracts into the cylinder shell . Structure sealing the inside of the cylinder more complex two -dimensional cylinder and one-way on its own oil line must have two levels . This large difference is that the hydraulic system uses two -dimensional cylinder valve must have changed direction ( distributor valve ) when you want to control this cylinder as shown below .

The cylinder can also split by rolling cylinder layouts : single cylinder rolling a cylinder floors or multiple floors ( telescopic ) .

Single rolling cylinder :

Single rolling cylinder is kind of a rolling cylinder sections are fastened together with results piston motion . This type of cylinder can only create a little more about moving the entire length of the cylinder , ie its working range is limited by the length of the rolling cylinder minus the thickness of the segment results and piston assembly inside the cylinder assembly .

Single rolling cylinder is commonly used types and have broad applications . Much of it has texture to rolling cylinders sticking out on one side of the cylinder . Some textured cylinder with cylinder rolling piston results in two directions (known as Double rod end cylinders ) . When a cylinder rolling poked the other side , the staff will " retract " into the cylinder shell .

Layered cylinder

Telescopic Cylinders are often layered or 2-3-4 or sometimes up to 6 floors . It consists of a cylindrical shell and tube should be nested together . The structure of this type can make cylinder stretched much longer journey dimensions of the cylinder base all rolled into withdrawal . This creates the ability to design details , textures lot of neat machine . However, many floor cylinders have higher costs than the single cylinder .

Cylinders are also two types of layered structures : one-dimensional cylinder and two -dimensional cylinder , cylinder type , however two -dimensional structure is complex and requires specially designed to prevent the risk .

There is also a hydraulic cylinder classified according to two types of structures are welded cylinders and cylinder assembly by - Rong gu ( Tie Rod cylinder ) .

Structural welding cylinders

This type of cylinder head is welded to the cylinder tube helps cylinders rigid structure suitable for heavy work on the mode of construction equipment or industrial motor skills .
