excavator arm cylinder

Hitachi excavator filters product requirements 1. Strength requirements, production integrity requirements, withstand pressure difference, bear installation external force, bear pressure difference alternating load 2. Requirements for smoothness of oil passage and flow resistance characteristics 3. Resistant to a certain high temperature, compatible with the working medium 4. The fibers of the filter layer cannot be displaced and fallen off 5, to carry more dirt 6. Normal use in high altitude and cold areas 7. Fatigue resistance, fatigue strength under alternating flow 8. The cleanliness of the filter element itself must meet the standard We are top supplier of Donaldson filters in China, you can get lowest price of original Donaldson filters from us!

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.

Hitachi Excavator Arm/boom/bucket Hydraulic Cylinder Excavator is the most widely used construction machinery. The shock load, harsh working environment, precision movement control makes extremely high requirements on hitachi arm cylinder. We can make full size excavator cylinders from mini excavators to extremely large HItachi excavators including Excavator Arm/boom/bucket hydraulic Cylinder / steering cylinders.

The basic 5 parts of the excavator boom cylinder: cylinder barrel and cylinder head, piston and piston rod, sealing device, buffer device, exhaust device. Among them, the cylinder (TUBE) consists of four parts: cylinder block, flange, cylinder bottom and bushing. The piston rod (ROD) consists of three parts: the rod body; the earring; the bushing.

The hydraulic excavator arm cylinder of the excavator is one of the executive components of the hydraulic system of the excavator. The excavator arm cylinder is used to perform linear reciprocating motion. It is characterized by simple structure, convenient maintenance, small mass, large force transmission, and small motion inertia. Realize remote control and automatic control.
