Since the beginning of this year, Blu-ray LED has been oversupplied and pressured on the price, which led to the weak operation of the epitaxial plant in the first half of this year. However, the upstream and downstream manufacturers have released the price reduction and deceleration information on the sapphire substrate and LED lighting.
In 2014, the LED lighting penetration rate will climb from 8% to 10% this year to 20%, becoming another major force in digesting chip capacity. Yiguang said that the price of mainstream LED lighting has fallen more than 20% this year. Although it is difficult to get rid of the price reduction trend next year, the decline has the opportunity to control within 20%, which is better than this year.
Yiguang currently adopts a dual-brand strategy on LED lighting, including EVERLIGHT and ZENANO, which have not yet officially entered the profit-breaking period. However, as the price of the chip is depressed and the terminal demand climbs, Yiguang estimates that the LED lighting penetration rate will be 20% next year. With only 8% to 10% of this year's penetration rate has grown significantly.
In addition, on the sapphire substrate, the price has temporarily bottomed out. The sapphire substrate factory pointed out that the ASP of the sapphire substrate changed little in the second quarter to the fourth quarter of this year. Compared with the earlier 9 to 10 seasons, the price is It has already bottomed out, and it remains to be seen whether the price will show a V-shaped trend or an L-shaped trend.
In some plants, the capacity of Slurry Pump is calculated based on the maximum demand of the process; which occurs only part of time. The excess capacity is usually controlled through a control valve; as a result, a lot of energy is wasted. In order to better meet the requirements of process capability or pressure, the flow control methods of throttling, by-pass control, speed control, impeller trimming and Variable Speed Drives (VFDs) are developed. Variable Frequency Drives (VFDs) are by far the most popular and effective type of adjusting the pump speed. Practice tells us that it is possible for VFDs to save 20-30% of the energy efficiency of the pumping system.
Product features:
1. Saving energy
The VFD controls the motor and automatically adjusts the motor load to make the motor run in an economical running state to achieve the effect of power saving.
2. Lower operating cost
The VFD can greatly reduce the energy cost of the motor, reduce the impact on the equipment after the frequency conversion start, and reduce the maintenance and repairing capacity, so the operation cost will be greatly reduced.
3. Improve pressure control accuracy
The VFD has accurate pressure control ability, which effectively improves the quality of system working condition.
4. Extend the service life of the motor
From the 0Hz starting motor, the starting acceleration time of the VFD can be adjusted to reduce the impact on the electrical and mechanical components of the motor when starting, so as to enhance the reliability of the system and prolong the service life of the motor. In addition, the VFD can effectively reduce the peak value of starting current to a minimum, and can reduce the impact on the grid and other electrical equipment.
5. Reduce the noise of the motor
According to the working condition of the motor, the motor running speed is slowed down obviously after the VFD is installed, so the noise of the motor running is effectively reduced.
