甚麽時刻選拉杆液壓缸,甚麽時刻選焊接液壓缸?二者的差別是甚麽?

我們先來看一個液壓油缸分類表:

 拉杆液壓缸 Tie rod cylinder 

拉杆液壓缸靠螺絲杆銜接前後缸蓋,小缸徑時爲四根螺絲杆,大缸徑會加多螺絲杆的數目來包管油缸的耐壓性,好比6根、16根,乃至20根。

分歧的應用壓力,螺絲杆的材質分歧,能夠爲A345號、合金鋼。

 

Tie rod style hydraulic cylinders use high strength threaded steel rods to hold the two end caps to the cylinder barrel. This method of construction is most often seen in industrial factory applications. Small bore cylinders usually have 4 tie rods, while large borecylinders may require as many as 16 or 20 tie rods in order to retain the endcaps under the tremendous forces produced.

拉杆液壓缸優勢 Advantages

1)易于拆裝、維修;

2)多爲尺度系列,半制品或制品有庫存,交期較短。

Tie rod style cylinders can be completely disassembled for service and repair, and they are not always customizable.

 

 焊接液壓缸 Welded cylinder

焊接液壓缸的後蓋焊接在缸筒上,油口焊接在缸筒上,前蓋與缸筒平日應用羅紋或螺栓固定。

Welded body cylinders have no tie rods. The barrel is welded directly to the end caps. The ports are welded to the barrel. The front rod gland is usually threaded into or bolted to the cylinder barrel. This allows the piston rod assembly and the rod seals to be removed for service.

 

 

焊接液壓缸的優勢 Advantages

1)全體的裝置尺寸小于拉杆油缸;

2)比拉杆油缸可以或許蒙受更大的壓力;

3)更輕易定制,好比特別油口、特別裝置方法、加裝鎖緊閥等

Welded cylinders have a narrower body and often a shorter overall length enabling them to fit better into the tight confines of machinery. Welded cylinders do not suffer from failure due to tie rod stretch at high pressures and long strokes. The welded design also lends itself to customization. Special features are easily added to the cylinder body, including special ports, custom mounts, valve manifolds, and so on.

 

 

 

總結:

1)裝置空間夠,壓力小,行程短,選拉杆液壓缸;

2)裝置空間有限制,壓力大,選焊接液壓缸;

3)應用壓力大,工況比擬卑劣,能夠須要按期改換密封件,選拉杆液壓缸;

4)油口地位有特別請求,或需加裝液壓鎖或均衡閥等,選焊接油缸。
