HC Consortium Fire News announced on September 1, 2014 that the revised "Detailed Implementation Regulations for Compulsory Certification of Fire Products" was implemented. The "Detailed Rules" clearly states that fire alarm products , fire protection products, fire-fighting equipment products, and fire-fighting equipment products must be mandatory. After the certification, the new version of the “Detailed Rules” was introduced, to a certain extent, to eliminate the phenomenon of unlicensed operation, unlicensed sales, etc., from the source of control of product quality, can be said to inject a shot of “strengthening” for product quality.

The stand-alone photo-inductor smoke fire detection alarm includes a sensor component for detecting smoke particles, a circuit board for signal processing, a buzzer for providing sound indication, an indicator lamp for providing light indication, and a battery device for supplying power. Its working principle is as follows: The stand-alone photo-electricity smoke fire detection alarm has a built-in photoelectric labyrinth that avoids ambient light interference as a smoke particle detection chamber, which contains an infrared light-emitting diode (IRLED) as a light-emitting element and a photodiode as a light-receiving element. The element and the light-receiving element are arranged in the same plane at acute angles or obtuse angles, and the light-receiving element cannot normally receive light from the light-emitting element. Infrared LEDs work intermittently, working hundreds of microseconds every few seconds to save battery power. In the absence of a fire, even if the infrared LED emits a pulsed beam, the photodiode receiving the light does not generate photocurrent because it does not receive the emitted light, and the detection circuit has no output signal. In the event of a fire, smoke particles enter the photoelectric labyrinth. Since the smoke particles scatter the light emitted by the infrared LED, some of the scattered light is received by the photodiode, and the photodiode generates a weak photocurrent. After being processed by the conversion and amplification circuit, it is sent to The MCU or dedicated chip performs analysis. When the smoke concentration reaches the set alarm threshold, an alarm sound and light indication are issued to remind people to quickly escape or extinguish fire.

According to relevant data, 62% of home fire deaths are due to the fact that no stand-alone smoke detection alarms or fire detection alarms have not been installed; households that have installed smoke detection alarms have been involved in the fire. At that time, the chance of escape was 63% higher than that of households that had not been installed or installed without effective work. Especially when the fire was small, the timely alarm of independent smoke detection alarms increased the chance of self-extinguishing and evacuation. The mortality rate was only 1 %. The main reason for installing a stand-alone smoke detection alarm but not working effectively is due to an unmounted battery or battery failure. The promotion and proper use of stand-alone photo-inductive smoke detectors are beneficial to save lives and reduce property losses. At present, 22 companies have already passed the certification of independent optical smoke detectors.

Metal Processing Machinery Parts

Metal processing machinery parts are components that are used in the operation of machines that are designed to shape, cut, form, or join metal materials. These parts are typically made from high-quality metals such as steel, aluminum, or titanium, and are designed to withstand the high temperatures, pressures, and stresses involved in metalworking processes.

Examples of metal processing machinery parts include:

1. Cutting blades and knives: These parts are used to cut and shape metal sheets, bars, and other materials.

2. Rollers and bearings: These parts are used to support and guide metal materials as they are processed.

3. Dies and molds: These parts are used to shape metal materials into specific forms and shapes.

4. Heating elements and burners: These parts are used to heat metal materials to high temperatures for processing.

5. Welding electrodes and tips: These parts are used to join metal materials together through welding.

6. Hydraulic and pneumatic components: These parts are used to power and control metal processing machinery.

7. Electrical components: These parts are used to provide power and control to metal processing machinery.

Overall, metal processing machinery parts are essential components that enable the efficient and effective processing of metal materials.
