离心泵是国民经济各领域中应用最广泛的通用机械,但是离心泵在使用前要灌注

Centrifugal pumps are the most widely used general-purpose machinery in various fields of the national economy. However, centrifugal pumps must be filled with a certain amount of water before use, and generally have low suction strokes, which restricts the development of centrifugal pumps. Based on this, a new type of vacuum centrifugal pump is designed. It is a combination of a rotary vane vacuum pump and a centrifugal pump. The rotary vane vacuum pump is used for vacuuming. The atmospheric pressure presses the water into the centrifugal water pump, and then passes The centrifugal pump drains water to achieve the purpose of pumping water. The article designs the structure of the new vacuum centrifugal pump, expounds its working principle, analyzes the feasibility of the new vacuum centrifugal pump, selects the typical components of the new vacuum centrifugal pump, and It has been verified by experiments, and the results show that the design of the new vacuum centrifugal pump is feasible. It avoids the trouble of filling and diversion, has the advantages of convenient operation and high degree of automation, and improves the suction stroke and work efficiency of the pump. The application of the pump provides the test basis.

Centrifugal pump is the most widely used general machinery in various fields of national economy, but the centrifugal pump must be filled with a certain amount of water before use, and the suction lift is generally not high, which restricts the development of centrifugal pump. Based on this, a new type of vacuum centrifugal pump is designed, which is composed of rotary vane vacuum pump and centrifugal pump. The vacuum is pumped by rotary vane vacuum pump, the atmospheric pressure will put the water pressure into the centrifugal pump, and then the water is drained by centrifugal pump to achieve the purpose of pumping water. This paper designs the structure of the new vacuum centrifugal pump, expounds its working principle, analyzes the feasibility of the new vacuum centrifugal pump, selects the typical components of the new vacuum centrifugal pump, and carries out experimental verification. The results show that the design of the new vacuum centrifugal pump is feasible, which avoids the trouble of filling and water diversion, The utility model has the advantages of convenient operation and high degree of automation, improves the suction lift and working efficiency of the pump, and provides a test basis for the application of the pump.

Centrifugal pump is the most widely used general machinery in all fields of national economy. However, centrifugal pump should be filled with water before use, and the suction range is generally not high, which restricts the development of centrifugal pump. Based on this, a new type of vacuum centrifugal pump is designed, which is composed of a rotary vane type vacuum pump and a centrifugal pump. The rotary vane type vacuum pump is used for vacuumizing, and the atmospheric pressure pushes water into the centrifugal pump, and then the centrifugal pump is used for draining water to achieve the purpose of pumping water. In this paper, the structure of the new vacuum centrifugal pump is designed, its working principle is expounded, the feasibility of the new vacuum centrifugal pump is analyzed, the typical components of the new vacuum centrifugal pump are selected, and the experimental verification is carried out. The results show that the design of the new vacuum centrifugal pump is feasible, it avoids the trouble of pouring water, has the advantages of convenient operation and high degree of automation, improves the suction range and working efficiency of the pump, and provides the experimental basis for the application of the pump.
