Landscape lighting should be in harmony with the natural night sky

Jinan City will gradually implement the centralized monitoring and time-sharing control mode of urban landscape lighting, and encourage the use of new technologies, new processes, new materials and new light sources in urban landscape lighting construction, from economical application, saving electricity, protecting the environment, green lighting, etc. In terms of urban landscape lighting, the landscape lighting is in harmony with the natural night sky. This is what the reporter learned today from the "Opinions on Strengthening the Management of Urban Landscape Lighting" issued by Jinan City. According to the regulations of Jinan City, the following areas and facilities should be constructed with landscape lighting facilities: buildings (structures) along the main roads; high-rise buildings, large and medium-sized public buildings; elevated roads, squares, parks, all kinds of bridges and culverts, all kinds of Public land; public sports and cultural facilities such as stadiums (halls), theaters, art galleries, museums, cultural relics protection units above the city level; outdoor advertising and commercial plaques, font sizes, logos; facilities of the municipal and district people's governments that should provide landscape lighting . Jinan City requires the implementation of centralized monitoring and time-sharing control mode of urban landscape lighting, and strives to reduce power consumption; strengthen the demonstration and review of landscape lighting design schemes, promote the use of energy-efficient products in accordance with lighting energy-saving design standards, and prohibit the use of inefficient Lighting products; to save energy, protect the environment, promote health as the purpose, actively promote green lighting, encourage all units and individuals to adopt new technologies, new processes, new materials, new light sources in urban landscape lighting construction, and guide urban landscape lighting Towards the direction of “high efficiency, energy saving, environmental protection and health”. It is understood that in the next period, Jinan City will compile and improve the overall planning of urban landscape lighting and detailed planning of landscape lighting for some major roads and key scenic spots, and formulate technical specifications for urban landscape lighting. Urban landscape lighting should be strictly designed according to standards and planned. Construction, pay attention to the scientific arrangement of brightness and color, avoid light pollution, make landscape lighting and natural night sky harmonious; speed up the legal system construction of urban landscape lighting, establish and improve laws, rules and regulations, and govern the construction, construction, construction, construction and construction Regardless of issues such as light pollution. Jinan City stipulates that the lighting time will be from 19:00 to 23:00 from May to October, and from 18:00 to 22:00 from November to April. It should be opened overnight in the holidays prescribed by the state. Activities that need to extend the opening time of landscape lighting facilities shall be implemented in accordance with the notice of the municipal construction administrative department.

Conveyor idler is the important part of all kinds of belt conveyor, it support the conveyor belt and holds the cargos. Such as Trough Idler, Return Idler, Impact Idler, which meet CEMA, ISO or any other standards. Conveyor idler designs are composed of more than one roller, where various parts of the idler connect to the conveyor belt at different points to keep the belt properly routed and operating well. These designs can also include metal racks for stability.

As a useful part of many industrial systems, conveyor idlers come in many different forms. Some common ones are inline idlers, inset or offset idlers, and return idlers. Inline, inset, and offset varieties are built in very specific ways to accommodate the belt according to optimal factors. Return idlers often deal with the undercarriage of the belt, which moves in the reverse direction. They can help to control aspects of belt return that contributes to the general function of the conveyor belt, such as the width or tension between the top belt and the return.

 

Conveyor idlers are used to take up extra belt length and provide adjustment for tensioning belt drives. Idler can be valuable belt drive components. bend Idler can alter belt paths, make the belt clear obstructions, or apply belt pre-tension. Idlers may remain in a fixed location, or may be adjustable to allow belt pre-tensioning and take up. Idlers may be applied to either the inside or backside of belts. Backside idlers are generally flat.

 

 

Structure of idler roller:

The internal components of idler rolls are essentially the same

The sealing arrangement protects the bearing from dust and moisture, as well as other environmental contaminants. In addition, the quality of idlers also varies depending on the quality of the individual components and of the manufacturing process. In addition to the idler roll itself, an idler set is supported in position by an idler bracket or base frame. These bases and brackets locate the individual idler rolls relative to each other and provide the necessary 'trough' angle.

 

1.The outer shells of idler rolls are generally manufactured from 89, 102, 108, 114, 127, 138, 152 and 178 mm tubing. 

2.The outer shells are generally closed off with an end cap of varying design.

3. The end caps are normally designed to house the anti-friction bearings (3)

4.and bearing dust seals

5. The anti-friction bearings support the non-rotating idler shaft

 

The idler shaft has special machined ends to positively location the idler within the base frame support bracket. and every one of our idlers passes through a comprehensive ISO 9001 quality.

 

 

Bearing Size

Most manufacturers use 6200 series deep groove ball bearings when constructing B series idlers, and either 6300 series ball bearings or regreasable tapered roller bearings when constructing C series idlers.

 

Special attention:

For our purposes, most CEMA idler manufacturers publish life expectations for 30,000 hours L10 life at 500 RPM.
