Axial Flow Pumps have lower heads but higher flow rates and are extremely versatile in low lift areas. The axial Flow Pump is divided into three types: vertical, horizontal and inclined, and its basic structure is the same. The impeller is fixed to the lower end of the pump shaft. There are usually 4 to 5 blades on the impeller. The blades are available in fixed, semi-adjustable and fully adjustable versions. The latter two can adjust the mounting angle of the blades within a certain range for efficient operation. The blades are bolted to the hub, the base of the blade is engraved with a reference line, and the hub has several mounting angular positions. The adjustment method is as follows: first remove the impeller, loosen the bolts, mobilize the blades to align the reference line with the required angular position line, and then tighten the bolt. This adjustment method is called semi-adjusting. The full adjustment is achieved by a special adjustment mechanism to adjust the blade mounting angle. The role of the guiding impeller is to convert the kinetic energy of the rotary motion of the impeller outlet liquid into pressure energy to avoid the impact and vortex loss caused by the rotation of the liquid.

Global caprolactam consumption in 2004 was about 4 million tons. London, England Tec?nonOrbiChem company predicts that in 2010 the annual growth rate of global nylon fiber demand will be less than 1%, nylon resin annual growth rate will be 4.3%. According to this estimation, the annual growth rate of caprolactam in the world will be less than 2% in 2010. By then, the global production capacity will reach 4.98 million tons and the output will be 4.65 million tons. In 2015, global demand for caprolactam is about 5 million tons, and China's demand will account for 20% of the global total.
The senior consultant of Tecnon OrbiChem believes that China imported nearly 450,000 tons of caprolactam in 2004, due to a total capacity of 140,000 tons/year of new capacity built in China's Nanjing DSM and Hunan Yueyang Sinopec Baling, which will be voted later this year. Use, it is expected that China's imports this year will be reduced. The reduction in China's caprolactam imports will also affect the global market structure.
Europe is a traditional export destination to Asia. As China adopted anti-dumping policies on caprolactam in Germany, the Netherlands, Belgium and Russia in the first half of last year and the first half of this year, these countries have reduced their exports to Asia. In addition, due to low profitability, the suspension of production in some European plants also affected European exports. However, U.S. exports to Asia are increasing because the production of U.S. fiber has declined.
Although global demand for caprolactam is expected to slow down this year, plant utilization rate will exceed 90% in the world, because some production capacity will be shut down, including Mitsubishi Chemical's 50,000 tonne/year plant in Fukuoka, Japan, which will be shut down at the end of September and will intensify Supply and demand tension.
Due to rising raw material prices, some companies announced new price increases. BASF will increase prices by 10%-12% from October 1st; DSM also plans to increase prices by 8% from October 1 and increase prices by 6% from November 1st. The US spot market price was lowered by 3 cents/lb to 95-98 cents/lb in August, and was unchanged from August, and was unchanged from August at 2100-2150 USD/ton (FOB ) and 2200-2240 US dollars / ton (cost price shipping, China).
Global caprolactam demand growth slows Production capacity of spinning industry in Taiwan Province of China and Korea decreased by approximately 100,000 tons
Many analysts in the industry recently predicted that global caprolactam demand growth will slow down. Nylon Business Consultant of PCI Company stated that in stark contrast to the sharp increase in demand in 2003 and 2004, global demand for caprolactam will be reduced by 1.2% this year. The decrease in demand was mainly due to the reduction in production capacity of the spinning industry in Taiwan Province and South Korea by approximately 100,000 tons this year.
