Self - priming centrifugal pump characteristics and principle of introduction

[Asia Fluid Network News] Self-priming centrifugal pump is mainly composed of impeller, pump body, pump shaft, bearings, seal ring, stuffing box and other parts. With the increasing use of such products in the aviation, marine, shipbuilding, chemical and petroleum industries, accelerating the understanding of such products is of utmost importance to the users. One self-priming centrifugal pump features and principles of self-priming centrifugal pump core knowledge. It is important for users to understand this information. Self-priming centrifugal pump features and principles of self-priming centrifugal pump features: 1, self-priming centrifugal pump with a simple structure, easy operation, smooth operation, easy maintenance features, with relatively easy to manipulate the structural features, the user can According to a certain method and scale to use, without complicated matters manipulation. In the use of the pipeline without the end of the valve, before the work just to ensure that the pump body can be stored quantitative oil, to ensure the smooth completion of the work, but also to ensure the normal use of the pump to ensure its service life. The centrifugal pump is mainly used for tankers or water ships, can also double as a stripping pump, stripping a good effect. 2, self-priming centrifugal pump with high efficiency, long life, strong self-priming ability and other strengths, in use can fully exert the upper hand, improve the efficiency and quality of work to ensure that save time and material resources, but also has a long life Superiority, not easily damaged, can play an important role and self-absorption capacity, the role of greater use. 3, self-priming centrifugal pump body, impeller is made of high-quality materials refined, sealed with carbide mechanical seal, durable, thus simplifying the piping system, but also improve the working conditions. Self-priming centrifugal pump principle: self-priming centrifugal pump with different over-flow material, mainly cast iron, stainless steel and other materials, according to the different material over-current, different material over-current with different characteristics and superiority, according to the detailed The situation is confirmed. Centrifugal pump flow and head range with different range of indicators, mainly in the flow range: 3.2-600m3 / h Head range: 12-80m, in use in accordance with certain parameters and flow to ensure that the use of cast important The role and value. Self-priming centrifugal pump has very good structural characteristics, in the production and use has a high role and value, in its work as long as the pump body to ensure that there is sufficient oil, it can maintain normal work. Self-priming centrifugal pumps have good effects, especially in cruise ships and ships, it can also serve as a cabin pump. There is a very good sweep effect.
