However, rising crude oil prices and rising labor costs have led to a significant increase in equipment rental costs. The fierce competition in the industry and disorderly market competition have caused companies to wage a price war. The business volume is still declining to a certain extent. The profitability is even lower than in previous years. Construction machinery has encountered a "cold stream". However, it is not necessary to be overly pessimistic. It is even more difficult to directly copy the mature industry standards of developed countries in Europe and America to China. After all, the domestic development environment is different from Europe and the United States.
In order to realize the continuous prosperity and development of construction machinery leasing industry, it is recommended to adopt the following five measures to strengthen: First, establish a credit system, improve relevant laws and regulations, and lay a solid foundation for the healthy development of the leasing industry; Second, China's construction machinery leasing industry More than 90% of the enterprises are small and medium-sized enterprises. Not only the overall strength is weak, but also the industry is in disorderly competition. It is necessary to conduct mergers and reorganizations, form leading companies, and promote sound development of the industry. Third, to enrich the brand range and product types of rental equipment. , And not only to provide leasing services to customers, but also to provide a comprehensive solution from business consulting, program planning, equipment selection, maintenance to customer return visits; Fourth, fully pay attention to and improve the leasing agreement, equipment delivery and recycling Equipment to do a comprehensive test, and pre-set the scope of responsibility for equipment loss; Fifth, training professionals.
It is understood that in the post-crisis era, the global economy is gradually recovering, and China’s engineering construction market is still booming. The construction of low-rent housing, high-speed railways, and urban rail transit has a huge demand for construction machinery. The potential of construction machinery leasing industry is huge, and the market prospects are promising. .
High Temperature Printing And Dyeing Pump
The main flow components of the high temperature printing and dyeing pump are the suction chamber, the impeller and the pressurized water chamber. The water suction chamber is located in front of the water inlet of the impeller, and plays the role of guiding the liquid to the impeller; the water pressure chamber mainly has three forms: a spiral pressure water chamber (volute type), a guide vane and a space guide vane; the impeller is the most important part of the pump. The important working element is the heart of the flow passage part, and the impeller consists of a cover plate and a middle blade. Before the high-temperature printing and dyeing pump works, first fill the pump with liquid, then start the high-temperature printing and dyeing pump, the impeller rotates rapidly, and the blades of the impeller drive the liquid to rotate. , in this process, the liquid in the impeller flows around the blades, and the liquid acts a lift force on the blades during the flow movement, and in turn, the blades act on the liquid with a force equal to and opposite to the lift force, and this force acts on the liquid. Do work, so that the liquid gets energy and flows out of the impeller, at this time, the kinetic energy and pressure energy of the liquid increase.
