掘削機バケットロッドシリンダー

The advantages and characteristics of the excavator bucket rod cylinder produced by our company are small size, light weight and high strength. The strength, fatigue design and adaptability of the cylinder body and piston rod are selected according to the load frequency analysis, processing technology and welding technology. Through ultrasonic wave Flaw detection inspection, as a high-voltage specification, achieves small size, light weight, high strength, and high reliability. The production and assembly processes are very sophisticated, and all cylinders shipped from the factory have been tested on high-pressure test benches, ensuring reliable quality.

Bucket rod cylinder block:

The material is made of alloy steel 27SiMn, which has high strength, small appearance and light weight. It is ground and rolled to a very high surface finish to minimize internal friction and extend the service life of the seal.

Advantage:

1. The materials of different accessories are made of different high-strength steels to enhance the overall performance of the hydraulic cylinder.

2. Provide a variety of surface anti-corrosion treatment solutions: Ni/C electroplating, ceramic spraying, laser cladding, QPQ, etc.

3. Integrated hydraulic locks, explosion-proof valves, oil pipes, etc. can be designed according to customer needs.

4. The design temperature range is wide (-25℃~+120℃), and customized services for higher or lower temperature cylinders can be provided.

5. The integral die forging earrings can be equipped with standard self-lubricating bushings, and can also be configured according to customer needs.

6. The mature buffer design reduces the impact of the hydraulic cylinder of the bucket arm during the excavation operation, does not reduce the excavation force, and affects the work efficiency.
