1. What is the function of the excavator boom bucket cylinder hydraulic cylinder?
Excavator boom bucket cylinder hydraulic cylinder is one of the key hydraulic components of the excavator, which is used to control the movement of the stick and bucket teeth on the excavator boom. It is powered by the pressure of hydraulic oil to realize the opening and closing and up and down movement of the excavation bucket.

2. What are the components of the structure of the hydraulic cylinder?
The hydraulic cylinder is mainly composed of cylinder body, piston, sealing device, cylinder head, cylinder seat and so on. The cylinder body is the main part of the hydraulic cylinder, the piston reciprocates in the cylinder body, and the sealing device is responsible for maintaining the sealing of the hydraulic cylinder.

3. What is the working principle of hydraulic cylinder?
The working principle of the hydraulic cylinder is to use the pressure of the hydraulic oil to input the hydraulic oil into the cylinder body of the hydraulic cylinder through the hydraulic pump to make the piston reciprocate. When the hydraulic oil enters one side of the cylinder, different forces are generated to drive the work of the hydraulic cylinder through the difference in the area of ​​the piston.

4. What are the common faults of hydraulic cylinders?
Common failures of hydraulic cylinders include oil leakage, sticking, bent piston rods, aging seals, etc. These failures may lead to a decrease in the working efficiency of the hydraulic cylinder or even failure to work normally, and it is necessary to repair and replace related parts in time.

5. What are the precautions for the maintenance of hydraulic cylinders?
The maintenance of the hydraulic cylinder includes regular inspection of the state and amount of hydraulic oil, cleaning the appearance of the hydraulic cylinder, and checking the looseness of the fasteners. In addition, it is also very important to pay attention to the quality of the hydraulic oil used and select the appropriate hydraulic oil, and to replace the hydraulic oil and seals regularly.
