introduction： Centrifugal pump is divided into general centrifugal pump and self-priming centrifugal pump two kinds。Self-priming centrifugal pump does not need to start irrigation，The small centrifugal pump adopts self-priming form，Easy to use。 one、Structural characteristics The efficiency of the self-priming centrifugal pump is determined by the hydraulic parameters of the flow channel of the impeller pump body and the rationality of the self-priming structure of the pump body，No factor can be ignored。BXType II are internal mixing self-priming centrifugal pumps，The main features of the pump are： 1、The hydraulic structure parameters of impeller and pump body choose large blade outlet installation Angle and outlet side width，The section area of the flow channel of the pump body is larger than that of the conventional design20-30%。

introduction： Battery maintenance goes through several stages，Its an evolving process，The advantages and disadvantages of each approach are discussed below 1、Measuring floating charge voltage method The setting of floating charge voltage has a very important effect on the life of the battery。In theory, the current generated by the floating charge voltage is required to compensate for the self-discharge of the battery。High floating charge voltage may cause battery positive electrode corrosion and water loss，The battery capacity decreases，The floating charging voltage is too low，It can also undercharge the battery，Cause battery lag，In severe cases, electrode sulphation occurs。The choice of floating charging voltage can be according to the manufacturer
