Submersible
pump is a multistage Centrifugal Pump, and it applies to tube 41/2 or
above it. Their discharge flow scope is 20-3000 steres at 50 HZ. And
grater discharge can be obtained by using frequency conference. The
impeller of Submersible pump adopted advanced CAD designation ,and it
has high efficiency. And customers could get the perfect product if they
offer the flow quantity, head of delivery and efficiency they need. At
the meantime, we also can design the degree of pump with different
material according to the condition of the well. The material such as
Ni-resist, high-chrome cast iron, copper aluminum alloy, stainless
steel. We could supply the pump for well with high sand and high gas
according to the requirement of customers.

What is the current status of the traditional electric light source to give the Chinese LED industry import and export market?
In recent years, LED products have been widely used in the world, and the total value of exports is increasing year by year. At the same time, more and more problems are gradually exposed. In 2015, the growth of export growth in the lighting industry is less than 10%, fell to single digits for the first time. In particular, the export volume of traditional electric light source products has fallen sharply, and the growth of the industry mainly comes from the export growth of LED lighting products. I. Overview of Import and Export Status of LED Industry According to customs data, the total import and export volume of China's LED industry in 2014 was 31,154,260,900 US dollars, an increase of 40.37%. The import value was 829,787,100 US dollars, an increase of 20.32% over the same period of last year; the export value was 228,561,478 US dollars, an increase of 49.41%; the trade surplus was 1,455,268,700 US dollars, an increase of 73.28%. Chart 1: 2012-2014 China LED industry import and export status table (unit: 10,000 US dollars, %) Second, the LED industry export product structure analysis as shown in the table below, from the perspective of export product structure, in 2014, China LED industry export products Sorted by amount, the top three are the unlisted lights and lighting products (tax codes), LED products (tax codes) and motor vehicle lighting products (tax codes), the export value of these three products The proportion is 62.21%, 21.80% and 8.65%. Chart 2: 2013-2014 China LED industry export product structure table (unit: one, kilogram, 10,000 US dollars) Chart 3: China's LED industry export product structure in 2014 (unit: %) Third, the LED industry imported product structure analysis as follows As shown in the structure of imported products, in 2014, China's LED industry imports were sorted by amount, and the top three were LED products (tax codes), electric lighting devices for motor vehicles (tax codes) and other semiconductors. Device products (tax code), the proportion of imports of these three products is 78.77%, 10.37% and 4.10%.
