Guangzhou governance "light pollution" from 1 May on the strict control of LED

It is forbidden to open LED billboards from 22:30 to 7:30 every day; it is forbidden to set up in the direction of the road and the direction of the car; it is not allowed to set up outdoor advertising in state organs, schools, houses, scenic spots and other places. sign. The reporter learned from the Guangzhou Municipal Management Committee on the 14th that the "Guangzhou Outdoor Advertising and Signboard Management Measures (Revised)" will be officially implemented on May 1. "Limited LED order" can be said to be a highlight after the revision of this management method. According to Article 12 of the Measures, outdoor advertising and signboards set up in the form of LED outdoor electronic display screens shall comply with the following regulations: It is forbidden to set up in the forbidden zone and strict control zone determined by the special plan for outdoor advertising (public information electronic display) Except for the wall of a multi-storey building, the height of the upper wall shall not exceed 35 meters; the wall of the high-rise building shall not exceed the "daughter wall" of the main building (the low wall outside the roof of the building) The upper edge is prohibited from being set in a direction perpendicular to the road and the direction of the incoming vehicle; it is prohibited to open from 22:30 to 7:30 the next day. The reporter learned that the introduction of the "Limited LED Order" is mainly based on the complaints of more and more "light pollution" in recent years. For this reason, the illumination, brightness and color requirements of outdoor advertising and signboards should also comply with the "Guangzhou Outdoor Advertising and The requirements of the Signature Setting Specification. In the arrangement of the “lights out” period, the relevant person in charge of the Guangzhou Urban Management Committee said that there are few regulations in other cities in China. The specification mainly refers to the characteristics of Guangzhou. “After 10:30, the business operations of various commercial circles are basically At the end, this arrangement is appropriate."

CNC Quenching Machine

The main machine consists of a bed, a double-layer precision workbench, a sliding mechanism for adjusting the top seat, a sliding assembly for the top seat, a moving and driving system for the table, a rotating and driving system for the spindle, a rotating and adjusting mechanism for the parts, a matching balance, a cover frame, and an electrical numerical control part. CNC quenching transformer can be used to move up and down the lifting table at a constant speed, chuck or thimble fixed roll or shaft rotation at a constant speed, inductor water quenching while. The machine tool adopts advanced numerical control technology, through programming can realize continuous scanning quenching, quenching at the same time, section continuous scanning quenching, section quenching at the same time. The machine tool is driven by a stepper motor controlled by a programming controller, while controlling the heating equipment and workpiece rotation as well as liquid injection. The body is made of steel plate and channel steel structure, and the guide rail is made of cylindrical linear rolling guide. The workpiece moving drive screw is ball screw, and the top moving drive is T screw.
Main configuration of quenching machine host:
1. Numerical control system control;
2, stepper motor drive;
3, ball screw transmission;
4, cylindrical linear guide, ball slider sliding;
5. Ac speed regulating motor drives the sprocket chain, and the optical bar rotates the workpiece;
6, AC reducer motor drive lead screw, lead screw is the top lifting;
7, solenoid valve control water spray;
8, equipped with control heating equipment plug.
Main features of quenching machine host:
1, the use of numerical control technology, with connection, at the same time, segment connection, segment at the same time and other quenching functions.
2, used for shaft, disk, pin, gear and other parts of the induction quenching.
3, can be configured with integrated quenching liquid circulation cooling system.
4, the use of profile structure body, high degree of automation.
Notes for CNC quenching machine tools: CNC quenching machine tools are used to heat quench or normalize large workpieces with industrial electric frequency, low voltage and large current. Use should comply with the safety rules of electricity.
