The high-pressure hose connecting the two hydraulic cylinders is bent forward in close contact with the crankshaft gear adjacent to the ninth main bearing, and there are unsafe factors, such as changing the joint position to make it bend backward, which affects the operation line of sight. The consequence is that the main bearing tensioner is scrapped. After careful study, combined with the opinions of the on-site operators, the design is modified to increase the height of the lower part of the cylinder, but at the same time reduce the height of the cap hole on the cylinder. The high-pressure hose connecting the cylinders is changed to a rigid straight tube and installed. Safety shield.
The four hydraulic cylinders of the cylinder head bolt tensioner prototype are jointed in the hydraulic system design. During the test, the distance of the last cylinder piston in the four hydraulic cylinders is found to be moved downward after the system is unloaded. Less than the other three cylinders, after analysis, it is determined that the cylinder is not well returned. Therefore, in order to ensure the synchronization of the four cylinders and increase the distance of the downward movement of the piston as much as possible, the workload of the manual compression piston is reduced, the working efficiency is improved, and at the same time, in order to ensure safety, the proper diameter of the oil pipe and the pipe joint is determined. Content of the study. Measures taken to re-purchase the high-pressure hose of the diameter under the same test conditions, design and manufacture the diameter, shirt, dumb and rigid oil pipes in order, carry out comparative experiments, observe the effect, and determine the best effect of the rigid oil pipe with the diameter. . In use, it has been found that the lever for dialing the nut in the supplied accessory has a short service life. This is due to oil stains and even sand between the nut and the screw during the disassembly operation. The lever is hard to be used when it is used. The material of the lever is hard and easy to break. The material is soft and easily deformed. Finally, it is scrapped on the diesel engine. The valve stem has improved, but the service life is still not ideal. This problem needs to be solved.
Advertisement lighting is a special lighting solution used to highlight and illuminate advertising media such as billboards, light boxes, signboards, in order to attract people's attention and effectively convey advertising information.
Billboard lighting uses LED technology as a light source, LED with high brightness, high energy efficiency, long life and other advantages. By precisely controlling the brightness and color temperature of the LED, rich colors and visual effects can be presented, thus making the advertisement more vivid and attractive.
In advertising display lights, lighting layout is very important. Generally, according to the shape and size of the advertising media, as well as the importance and key points of the advertising content, the design of a suitable lighting scheme. Through the distribution and angle setting of the lamps, it can ensure that the entire advertisement is evenly illuminated, avoiding dark or over-exposed areas, so as to improve the visibility and recognition of the advertisement.
In addition, outdoor advertising lighting can also be applied to some special effects, such as flashing, changing colors, gradients, etc., to attract attention and increase interest. The choice of these effects usually depends on the theme of the AD and the goal of the campaign.
Advertising sign lighting is widely used in commercial environments, including shopping malls, shops, roads, subway stations and so on. It can not only attract the attention of consumers, increase brand exposure and sales opportunities, but also create a unique urban landscape at night to enhance the beauty and vitality of the city.
All in all, advertising lighting is a lighting solution specifically designed to highlight and illuminate advertising media. Through LED technology and well-designed lighting schemes, it can improve the visibility and recognition of advertisements, attract people's attention, and effectively convey advertising messages.Advertisement Lighting,Billboard Lighting,Advertising Display Lights,Outdoor Advertising Light,Sign Lighting
