Problems solved by technology

While the self-priming pump is automated, there are still problems such as water shortage and impeller stuck. To solve these problems, it needs to be equipped with an intelligent circuit board with corresponding functions. Among the existing intelligent self-priming pumps, only the one with a built-in pressure switch Smart Electric Board's Smart Self-Priming Pump for Closed Circuits

Abstract

The invention provides an intelligent self-priming pump. The intelligent self-priming pump comprises a power input end, a main winding branch circuit and a secondary winding branch circuit. The main winding branch circuit and the secondary winding branch circuit are connected to the power input end in parallel. The secondary winding branch circuit comprises a secondary winding coil L2 and a working capacitor C and is formed by connecting the working capacitor C and the secondary winding coil L2 in series. The main winding branch circuit comprises a main winding coil L1. The intelligent self-priming pump is characterized by further comprising a control circuit; a relay KM is arranged on the control circuit; a normally-open contact of the relay KM is connected to the power input end of the pump so as to control power on-off of the pump. By using the intelligent self-priming pump, on-off of the pump can be controlled through a water level switch; and moreover, the functions of automatically turning off the pump and preventing the pump from getting stuck in the absence of water are achieved.

Description

Technical field [0001] The invention relates to a water pump, in particular to an intelligent self-priming pump. Background technique [0002] In the existing technology, there are several ways to realize the automation of the self-priming pump: On the closed pipeline, a built-in pressure switch can be placed on the self-priming pump with low power, and the pump can be controlled by sensing the water pressure. On-off, if it is a high-power self-priming pump, an external pressure switch can be placed on the pipeline, and then a pump control box can be used to control the on-off of the pump; if there is a water tank, a water level switch can be placed in the water tank. The water level switch of the low-power self-priming pump can directly control the on-off of the pump, and the water-level switch of the high-power self-priming pump can control the on-off of the pump through a pump control box. While the self-priming pump is automated, there are still problems such as water s...
