Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vertical self-priming pumps, in particular to a vertical self-priming pump. Background Art
[0002] A vertical self-priming pump is a liquid transportation device widely used in industrial and civil fields. Its main feature is that it can automatically complete the exhaust work after startup, thus realizing the self-priming function without additional drainage. The design of such pumps usually includes a special self-priming device, enabling it to generate negative pressure inside the pump body, quickly suck in the liquid and transport it. The vertical self-priming pump has the advantages of compact structure, small floor area, and convenient operation, and is suitable for various occasions requiring efficient and stable liquid transportation, such as water treatment, chemical industry, pharmaceutical industry, etc.
[0003] A vertical self-priming pump is an efficient liquid transportation device, usually used in conjunction with equipment such as water storage tanks, filters, and pipeline systems. Its structure mainly includes a pump body, an impeller, a pump shaft, and a self-priming device. In terms of working principle, the vertical self-priming pump generates centrifugal force through the rotation of the impeller, causing the liquid to form negative pressure inside the pump body, thereby realizing the self-priming function. After startup, the liquid is quickly introduced into the pump chamber through the self-priming device, and then is pressed into the output pipeline through the rotation of the impeller, realizing the continuous transportation of the liquid. Due to its good self-priming performance and compact design, this pump is widely used in fields such as agricultural irrigation, building water supply, and industrial liquid transportation.
[0004] Some vertical self-priming pumps have problems such as large particles entering the inside of the self-priming pump, which may damage the impeller. In addition, it will also cause the rotation of the impeller to be blocked due to being stuck in the gap between the impeller and the pump shell, increasing the motor load, overheating or burning out the motor, and shortening its service life. And when it is cold, the water in the pump body of the vertical self-priming pump freezes. The expansion of the ice will cause the pump body to rupture, and components such as the impeller will be frozen. Forced startup will cause the motor to be overloaded, the shaft to deform and break, increasing the risk of motor burnout, greatly affecting the normal operation performance of the pump, reducing efficiency and service life. The subsequent maintenance and replacement of components are costly and time-consuming, seriously affecting the production and use process. Therefore, a vertical self-priming pump is proposed to solve the above problems. Summary of the Utility Model
