Excavator Hydraulic Cylinder

There are many types of faults in the excavator engine. I have explained the problems of abnormal noise, oil burning, carbon deposition, etc. before. What happened to the engine speed drop when the excavator was working? How should we solve it?

The engine speed drop refers to the failure of the engine speed drop during the excavator operation. The performance of the speed drop is divided into two types, one is a slight speed drop within 200 rpm, and the other is a serious speed drop over 300 rpm. It is very likely to cause the excavator to suddenly turn off. The main reasons for the engine speed drop of the excavator are the following 8 points.

Common cat excavator cylinder connection forms:
(1) Flange type connection has simple structure, convenient processing and reliable connection, but requires sufficient wall thickness at the end of the cylinder to install bolts or screw in screws. It is a commonly used connection form.
(2) The half-ring connection is divided into two connection forms: the outer half-ring connection and the inner half-ring connection. The half-ring connection has good manufacturability, reliable connection and compact structure, but weakens the strength of the cylinder. The application of half ring connection is very common, and it is often used in the connection of seamless steel tube cylinder and end cover.
(3) There are two types of threaded connection: external thread connection and internal thread connection, which are characterized by small size, light weight and compact structure, but the structure of the cylinder end is complex. light occasions.
(4) The tie rod connection has simple structure, good manufacturability and strong versatility, but the volume and weight of the end cover are large, and the tie rod will stretch and become longer after being stressed, which will affect the effect. Only suitable for medium and low pressure hydraulic cylinders with small lengths.
(5) Welded connection, high strength, simple manufacturing, but easy to cause cylinder deformation during welding.

Hitachi hydraulic cylinder for various excavators can be designed and manufactured according to customer requirements:
1. Select precision cold-drawn seamless steel pipe;
2. Cylinder bore size: ф30—ф600mm; length up to 8 meters;
3. The piston rod is made of 40Cr steel, and the diameter of the piston rod is ф5—ф300mm;
