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.

Abstract: According to Luo Baihui, secretary general of the International Association of Mould & Hardware Plastics Industry Suppliers, this cruise ship named “Beijiang Pearl†was jointly developed by the ship inspection department of Qingyuan Maritime Safety Administration and Qingyuan Ship Design Department, and produced by Qingyuan Baimiao Shipyard.
According to Luo Baihui, secretary general of the International Association of Mould & Hardware Plastics Industry Suppliers, the cruise ship named “Beijiang Pearl†was jointly developed by the ship inspection department of Qingyuan Maritime Safety Administration and Qingyuan Ship Design Department, and produced by Qingyuan Baimiao Shipyard. In addition, the Qinghai Maritime Department actively guided the shipyard to carry out research and development of new ship types, and organized the research on the feasibility of “Beijiang Bulk Cement and Coal Multipurpose Transport Vessels†to promote the successful transformation of Qingyuan Shipbuilding Industry.
On the afternoon of March 6, the first independent research and development in Qingyuan City, the luxury cruise ship made by the new technology of CNC cutting was successfully launched, and the maiden voyage was launched in the waters of Baijiang Temple in Beijiang.
According to Luo Baihui, secretary general of the International Association of Mould & Hardware Plastics Industry Suppliers, the cruise ship named “Beijiang Pearl†was jointly developed by the ship inspection department of Qingyuan Maritime Safety Administration and Qingyuan Ship Design Department, and produced by Qingyuan Baimiao Shipyard. Its hull is a steel skeleton with a cost of more than 5 million yuan. It adopts advanced and fashionable streamlined design. The interior is elegant and comfortable. It is equipped with radar, satellite navigation equipment and central air-conditioning. It has become a landscape of Beijiang.
"This cruise ship embodies Qingyuan's most advanced and mature shipbuilding technology. The shape design and mold production are all completed by numerical control technology." According to Luo Baihui, "Beijiang Pearl" is the first independent research and development in Qingyuan City, using digital lofting and CNC cutting. The tourism ship produced by the new technology has proved that the Qinghai water tourism economy has entered a new era. The Qingyuan shipbuilding industry has turned “magnificently turned†into the era of digital precision control and green environmental protection.
As a key scenic spot in the Feixia Scenic Area, the renovation and renovation of tourist ships is imminent. In response to this situation, Qingyuan Maritime Department has taken effective measures to promote the development of Qingyuan's water tourism industry, speeding up the management plan for existing tourist ships, and plans to divide nearly 100 old tourist ships in Feixia Scenic Area within five years. Batch elimination and renovation. At present, Qingyuan Maritime has launched three different levels of tourist boat programs, which have proposed new upgrade requirements for the quality, appearance, interior and function of tourist ships, which brings opportunities and challenges to Qingyuan's shipbuilding industry.
In China, in the past, the big ships were hand-punched, and some sand-picking vessels and cargo ships were built. The craftsmanship is relatively rough, and the cruise ships are basically still blank. Under the guidance of the Qingyuan Maritime Department, from 2010 onwards, the responsible persons of the shipyards in the area have been in abundance. Going out to learn new shipbuilding techniques all over the country, guiding shipyards to standardization, scale, and intensive development, introducing advanced technologies such as shipboard hardening, CNC cutting, digital stakeout, etc., greatly improving the quality of shipbuilding technology in Qingyuan area and shortening shipbuilding The cycle reduces production costs and enhances shipbuilding competitiveness.
In addition, the Qinghai Maritime Department actively guided the shipyard to carry out research and development of new ship types, and organized the research on the feasibility of “Beijiang Bulk Cement and Coal Multipurpose Transport Vessels†to promote the successful transformation of Qingyuan Shipbuilding Industry. It is understood that there are already three shipyards in the Qingyuan area that have invested heavily in the introduction of advanced shipbuilding equipment. Compared with the past, the construction of a similar ship, the construction period is reduced by 20%, the cost of manufacturing materials is reduced by 5%, shipbuilding capacity and economy. The benefits have been greatly improved.
