Xiao Hongqing, secretary-general of the Taiwan LED Lighting Industry Alliance and professor of electrical engineering at the Taiwan University of Science and Technology, said in the recent GreenLighting2014 China (Shanghai) International Semiconductor Lighting Application Technology Forum that the three major indicators of LED lighting timing are CRI80~85 (visual indicators). ; Lm / W170 (performance indicators); Lm / US $ 200 (market indicators). Xiao Hongqing said that when these three indicators are completed, energy conservation will not be the focus of users. Under the premise that the chip reaches the performance index, the lighting system light efficiency will reach 135lm/W, LED bulb light effect is 85lm/W; LED lamp tube 125lm/W, beyond T5 fluorescent tube; with the further development of chip technology, when the chip When the luminous efficiency is 200lm/W, the system efficiency (system efficiency 75~80) will reach 160lm/W, surpassing the high-pressure sodium lamp and all the current traditional light sources. Energy saving will become the basic essential performance of LED lighting. When performance indicators are no longer the focus, solving problems such as glare and glare will become the key to LED lighting applications. The reliability, stability and low light decay of LED lighting will become the focus of the LED market. Xiao Hongqing said that the development of LED lighting needs to first understand the needs of customers and the market, and what exactly do consumers and consumer markets want? What do you care about? As can be seen from the current industry trends, consumer concerns have gradually moved from performance to function. In the future, smart lighting and health lighting have become the focus of the LED lighting market. What kind of function should LED lighting have? Xiao Hongqing believes that the first is the high-quality lighting environment and vision health, as well as the purchase and construction costs that consumers think are reasonable. Some users also need high-efficiency lighting equipment and convenient control systems, and the convenience of maintenance and equipment compatibility. The problem is taken into consideration, considering the overall energy efficiency and electricity cost. Although LED lighting consumes less energy, Xiao Hongqing emphasized that the environmental recycling of LED lamps and other environmental issues are completely ignored by the industry. In addition, Xiao Hongqing said that the current industrial structure is still a lot of companies fighting alone, a loose sand, self-sweeping snow; and facing the challenges of the international LED lighting giants, domestic enterprises need to adopt alliance integration operations, brothers concentric, their offense Kim, work together to fight the world. Especially for small and medium-sized enterprises, in order to not be eaten, they must have the ability to look after the house. At the end of the speech, Xiao Hongqing said frankly that the domestic LED industry needs to create high-end lighting products, get rid of the low-cost and blind costdown thinking, and jointly develop the LED lighting industry.
Centrifugal Slurry Pump
Slurry Pump includes horizontal slurry pump, vertical slurry pump, submersible slurry pump, etc. For horizontal slurry pump, there are metal slurry pump and rubber lined slurry pump.
Horizontal Metal slurry pumps are cantilevered slurry pumps, horizontal centrifugal slurry pump, centrifugal pump theory slurry pump, heavy duty centrifugal slurry pump. They are designed for the handling highly abrasive, high density slurries in the metallurgical, mining, coal, power, building material and other industrial departments etc. The pumps of this type also may be installed in multistage series.
The frame plates have replaceable wear-resistant metal liners. The impellers are made of wear-resistant high chrome alloy .
Horizontal Metal slurry pumps may be adoptable of gland seal or expeller seal. The discharge branch can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications.
Rubber lined slurry pumps and spare parts can fully interchange with world famous brand. These pumps are of heavy-duty construction, designed for continuous pumping of highly abrasive and corrosive slurries. They feature a wide choice of replaceable abrasion resistant metal or moulded elastomer casting liners and impellers, which are all interchangeable within a common costing assembly.
BV pumps are vertical, centrifugal slurry pumps submerged in sump to work. They are designed for delivering abrasive,large particle and high density slurries. These pumps have no need of any shaft seal and sealing water. They can also be operated normally for insufficient suction duties. Wet parts of type BV pump are made of abrasion-resistant metal. All parts of type BVR pump immersed in liquid are lined with rubber outer liner. They are suited to transport non-edge angle abrasive slurry.
ZQ(R) series of slurry pumps are hydraulic devices composed of coaxial motors and pumps that are submerged in the fluid to work. These pumps are characterized by unique structure wide passage, high capacity of removing sewage, and high quality materials, offering excellent corrosion resistance. They are suitable for transferring the liquid containing solid particles, like sand, coal slag, and tailings, and removing slurries in metallurgical plants,mines, steel mills, or power plants, as an ideal alternative to traditional pumps for taking away slurries
