Excavator cylinder: The hydraulic cylinder is a linear actuator whose output force is proportional to the effective area of the piston and the pressure difference between both sides. â€Its function is to convert hydraulic energy into mechanical energy. The input of the hydraulic cylinder is the flow and pressure of the fluid, and the output is the linear motion speed and force. The piston of the hydraulic cylinder can complete linear reciprocating motion, and the output linear displacement is limited. The hydraulic cylinder is an energy conversion device that converts hydraulic energy into mechanical energy for reciprocating linear motion. The hydraulic cylinder is basically composed of a cylinder tube and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device.

Qian Huantao said that the inclusion of the equipment manufacturing industry in a limited number of target systems is not only due to the large scale of its existing total volume. More importantly, equipment manufacturing industry is a core component of industry and is a national. Economic development is an important foundation for industrial development in particular. The establishment of a strong equipment manufacturing industry is the fundamental guarantee for enhancing the industrial synthesis forces and realizing the new type of industrialization. The level of industrial restructuring and transformation and upgrading in a region is a major sign of equipment manufacturing.
"Comparably, when we started to formulate this action plan last year, the Ministry of Industry and Information Technology was also working on the "Made in China 2025 Plan"." Qian Huantao said that the main thrust of the program is to develop smart manufacturing; one of the main goals It is necessary to develop advanced equipment manufacturing industry and vigorously support the development of strategically important industries such as CNC machine tools and basic manufacturing equipment, aviation equipment, marine engineering equipment and ships, and automobiles that are closely related to the national economy, national defense construction, and people’s lives. The international advanced level has already made breakthroughs in key industries such as space equipment, communication network equipment and rail transit equipment. "As a result, when we prepared our province's action plan, we repeatedly studied and discussed with the leaders and experts of the Ministry of Industry and Information Technology. While conducting comprehensive research and planning, we also focused on scientifically setting and guiding the goals and directions of the equipment manufacturing industry. We have now seen what we have seen, both in the development of new industries, high-end equipment manufacturing, and in the transformation and upgrading of traditional industries, including automobiles, construction machinery, ships, and agricultural machinery."
Cylinder maintenance method:
One. The hydraulic oil should be replaced regularly during the use of the cylinder, and the system filter should be cleaned to ensure cleanliness and prolong its service life.
two. Each time the oil cylinder is used, it needs to be fully extended and retracted for 5 strokes and then run with load. Doing so can exhaust the air in the system and preheat the systems, which can effectively avoid the presence of air or water in the system and cause gas explosion (or scorch) in the cylinder body, which will damage the seals and cause leakage in the cylinder. Wait for failure.
three. Control the system temperature. Excessive oil temperature will reduce the service life of the seal. Long-term high oil temperature will cause permanent deformation of the seal or even complete failure.
four. Protect the outer surface of the piston rod to prevent bumps and scratches from damaging the seals. Frequently clean up the mud and sand on the dust ring of the cylinder dynamic seal and the exposed piston rod to prevent difficult-to-clean dirt sticking to the surface of the piston rod Into the inside of the cylinder, damage the piston, cylinder or seal.
Fives. Check the connections of the threads and bolts frequently, and tighten them immediately if they are loose.
six. Frequently lubricate the connecting parts to prevent corrosion or abnormal wear in the absence of oil.

Equipment manufacturing industry is an important pillar of Shandong's industrial economy. It is both a traditional advantageous industry and a strategic emerging force. On the afternoon of the 13th, the director of the Shandong Provincial Economic and Information Committee and party secretary Qian Huaota pointed out at the press conference of the Information Office of the People's Government of Shandong Province that at present, the equipment manufacturing industry’s operating revenue accounts for 27% of the province’s industry, hopefully. It will exceed 28% by 2017 and 30% by 2020.
