The Maintenance Measures of Construction Machinery


The Maintenance Measures of Construction Machinery

First Tracy McGrady Jersey , establish a sound engineering machinery maintenance market

(1) Establish a regional service network.

(2) Establish industrial after-sales service network.

(3) Establish industrial management service network to promote the markets orderly operate.

Second, improve the mechanical maintenance system and management system

(1) Combined with China's national conditions Steve Francis Jersey , focus on reliability, integrating regular check and actual situation together;

(2) The maintenance system should be diversified Ryan Anderson Jersey , complex and flexible.

(3) The reform of maintenance system should be combined with the integrated management of the equipment.

(4) Set up management department with the rights and responsibilities unified as soon as possible that responsible for macroeconomic regulation and control of construction machinery maintenance industry, and planning the overall development.

(5) Construction machinery maintenance and management must be done from planning and design phase.

Third Robert Horry Jersey , strengthen the routine maintenance

Routine maintenance of construction machinery generally includes cleaning maintenance, lubrication maintenance and sturdy maintenance of three. In the building construction period PJ Tucker Jersey , construction machinery should be given appropriate maintenance means according to different operating environment and operating temperature.

Fourthly, improve maintenance techniques and methods

(1) Base on condition monitoring and fault diagnosis technology

Practice shows that the engineering with more advanced mechanical properties and more complex structure is more dependent on condition monitoring and fault diagnosis technology.

(2) Develop improved maintenance and composite maintenance technology. Improved maintenance refers to repair the old machine by new devices Nene Jersey , new materials and new technology to make machine close to the performance of new machine after the repair. In the future, with the wide application of advanced engineering techniques in construction machinery Michael Carter-Williams Jersey , the update cycle of new construction machinery will be further reduced; restorative maintenance will be replaced by improved maintenance.

WASHINGTON， Dec. 7 (Xinhua) -- People who have an optimistic view on life are more likely to live longer， a U.S. study said Wednesday.


The study， published in the American Journal of Epidemiology， analyzed data from 2004 to 2012 from 70，000 women enrolled in the Nurses' Health Study， a long-running U.S. study tracking women's health via surveys every two years.


The researchers looked at participants' levels of optimism and other factors that might play a role in how optimism may affect mortality risk， such as race， high blood pressure， diet， and physical activity.


It found the most optimistic women， or the top quartile， had a nearly 30 percent lower risk of dying from any of the diseases analyzed in the study compared with the least optimistic women， or the bottom quartile.


The most optimistic women had a 16 percent lower risk of dying from cancer; 38 percent lower risk of dying from heart disease; 39 percent lower risk of dying from stroke; 38 percent lower risk of dying from respiratory disease; and 52 percent lower risk of dying from infection.


Previous studies have linked optimism with reduced risk of early death from cardiovascular problems， but this was the first to find a link between optimism and reduced risk from other major causes.


"While most medical and public health efforts today focus on reducing risk factors for diseases， evidence has been mounting that enhancing psychological resilience may also make a difference，" said Eric Kim， research fellow at the Harvard T.H. Chan School of Public Health and co-lead author of the study.


"Our new findings suggest that we should make efforts to boost optimism， which has been shown to be associated with healthier behaviors and healthier ways of coping with life challenges."
