Energy Saving Details Of China Passenger Elevator
2022-6-15
Seven common energy-saving methods of China Passenger Elevator :

(1) Realize energy saving and consumption reduction in elevator software control, such as establishing an effective control traffic mode, setting the elevator operation mode to acceleration and deceleration variable parameters, minimizing the number of elevators stops, and determining the distance between different floors through simulation software... see more simulation. the best operating curve.

(2) Take advantage of the elevator machine room on the roof, and make full use of solar energy as the supplementary energy for the elevator through the transformation.

(3) Improve the elevator mechanical transmission and electric drive system, adopt planetary gear reducer, frequency conversion voltage regulation, and speed regulation drive system, which can effectively reduce the energy consumption of the elevator, and its power loss can be reduced by more than 20%.

(4) An Elevator energy feedback device is a high-performance feedback braking unit dedicated to elevators. It can effectively convert the regenerative electric energy stored in the capacitor of the elevator inverter into AC electric energy and send it back to the power grid so that the elevator becomes a green "power plant" to supply power to other equipment, which has the effect of saving electric energy. The regenerative power recovery efficiency is as high as 97.5%. In addition, instead of electricity Resistance, energy consumption reduces the ambient temperature of the machine room, improves the operating temperature of the elevator control system, and prolongs the service life of the elevator. The machine room does not need to use cooling equipment such as air conditioners, which indirectly saves electricity.

(5) The elevator car lighting system is updated, and LED lighting lamps are used, which saves about 90% of lighting power, and the life of LED lamps is about 40 times that of conventional lamps.

(6) Using advanced elevator control technology, including elevator car unmanned automatic light-off technology, driving building intelligent management technology, etc., can achieve a good energy-saving effect.

(7) By strengthening the maintenance management of the elevator in the later stage, taking effective operation maintenance and maintenance management measures, reducing the elevator failure rate, and prolonging the service life of the elevator, it is also the embodiment of the elevator energy-saving management measures.

China Wooden Crafts Manufacturers Introduces The Selection Strategy Of Wooden Toys
2022-6-14
China Wooden Crafts Manufacturers introduces how to choose wooden toys for children?

1. Open the package to see if there is any odor
General wooden toys have more or less the smell of wood itself. If the smell is too strong, it means that the toy is too tightly sealed or the paint on the surface of the toy has problems. If the plastic packaging is too tight and the toy... see more has a smell, you only need to put the toy in a cool and ventilated place for 2-3 days to solve the problem of the smell. Under normal circumstances, as long as it is a toy paint purchased from formal channels, there should be no problem.

2. Check whether the surface of the wooden toy is smooth and free of burrs
Most wooden toys are handmade, so the smoother the surface of the toy, the finer the workmanship. Parents should choose toys with a smooth surface and no burrs to prevent the baby from being stabbed by burrs when playing.

3. Toy materials
The materials used in wooden toys are roughly divided into three categories. One is imported rubber wood, beech, etc. This kind of wood has fine texture, good hand feel and durability, but the relative price is higher than that of ordinary toys. One is basswood, pine, etc. This kind of wood has beautiful texture and light hand feel, and is mostly used in general toys. One is the splint toys, which are generally suitable for the production of make-up or plane toys. Parents can choose suitable wooden toys according to their own preferences.

4. Check the age group
Each toy has a suggested age for toddlers, and parents should choose toys that are appropriate for your child's age group. Babies under the age of 3 have poor self-protection awareness and are easy to put toys in their mouths or nostrils. Therefore, when buying toys, they should choose toys with larger building blocks, simple shapes and smooth surfaces; babies over 3 years old have rich sensory experience. , Safety awareness is relatively increased, and parents can choose more sophisticated toys.

The steps of the polishing method are generally to burn the wood material to a... see more charred black and then use the polishing method to add different pigments.

2. Oxtail method, wooden crafts with stripes are very popular in the market, which is the result of using the oxtail method. The practice is generally to use a brush shaped like an oxtail to paint the surface of the wooden handicraft, and then quickly hit the surface of the wooden handicraft to form stripes on the surface.

3. Friction method, the fashion industry has the concept of being old and broken, and wood products often have this effect. Wooden handicrafts using the friction method will give people a sense of age. After the lacquer of the wooden crafts is dry, rub with different or uniform paints on different areas of the wooden crafts as needed to form a worn-out effect.

4. Fire smoking method. Wooden handicrafts also pay attention to techniques and skills. The surface of many wooden handicrafts will have a blackening effect as if they have been roasted by fire. In fact, this method is called the fire smoking method, which uses a small flame to smoke the surface of the wooden handicrafts to form a smoked effect.

5. Worm-eaten method, according to our common sense, wood that has been worm-eaten cannot be used for processing. The same is true, but the method to simulate moth-eaten will be welcomed by the public. The practice of this method is to heat an iron nail, and then use a hammer to drive it into the wooden handicraft, imitating the way of the moth, and following the grain of the wooden handicraft. But note that not to go too far, so as not to damage the wooden crafts.
