Xichai recently held a postdoctoral research station report meeting, and Dr. Wang Zhong's post-doctoral report on the “Design and Research of Diesel Particulate Recycling Control Strategy†was reported on the site. This topic is closely related to the development of diesel engine research and development of Xichai , and it has certain forward-looking and advanced nature. After the completion of the project, the application of common rail injection technology to diesel engines can be promoted, diesel exhaust emissions can be effectively reduced, noise can be improved, fuel consumption can be reduced, and the overall performance of the diesel engine can be improved. This will make a significant contribution to upgrading the overall technical level of the diesel engine industry in China. .
Xiehai director Qian Hengrong pointed out that "Design and Research on Diesel Engine Particulate Recycling Control Strategy" is a key content of diesel engine after-treatment technology and has important practical significance for the future development of diesel engines . For the postdoctoral scientific research station construction and research, Qian Hengrong said that the topic should closely follow the actual situation and development direction of the enterprise and solve the problems of enterprise development. It is hoped that postdoctoral and whole-plant scientific and technical personnel will boldly innovate, work hard and produce early results.
Tower cranes typically use a combination of fixed and movable pulleys to lift and lower heavy loads. The pulleys are usually attached to the jib or boom of the crane and are used to change the direction and increase the mechanical advantage of the lifting system.
Some common types of pulleys used in tower cranes include:
1. Fixed Pulleys: These are stationary pulleys that are mounted at a fixed point on the crane. They change the direction of the lifting force and help distribute the load evenly.
2. Movable Pulleys: These pulleys are attached to a movable block that can be raised or lowered along the jib or boom of the crane. They provide additional mechanical advantage and allow for easier lifting of heavy loads.
3. Trolley Pulleys: These pulleys are used in conjunction with a trolley system that allows the crane to move horizontally along the jib or boom. The trolley pulleys help distribute the load evenly and provide smooth movement of the crane.
4. Counterweight Pulleys: Tower cranes often use a counterweight system to balance the load being lifted. Counterweight pulleys are used to attach the counterweights to the crane and ensure proper balance and stability.
It's important to note that the specific configuration and number of pulleys used in a Tower Crane can vary depending on the crane model and lifting capacity.
