The improved pump's control box installed frequency inverter cooled by pump's discharge water for operation of booster pump system

摘要

The present invention is a booster pump system for supplying water at a constant pressure to each consumer of a multi-unit house such as an apartment, and has a vertical connector in the inner center of a control box in which a micro controller adopting a frequency inverter is incorporated. By connecting the upper and lower ends of the connecting pipe to the middle of the discharge pipe,;As the connection tube is cooled by the temperature of the high pressure discharged water at the pump side along the discharge tube and the connection tube, the inside of the control box is rapidly cooled, so the circuit inside the control box can be efficiently cooled without the need for a separate cooling means. Significantly reduced and of course, there is no need for a separate cooling means, which greatly reduces manufacturing costs. The control box is placed on the upper side of the pump and the branch pipe is drawn out on the upper side of the pump, minimizing the installation space of the entire system and The present invention relates to a control box incorporating an inverter for a booster pump system, which has an improved cooling structure, which reduces the cost of wire materials and enables easy finishing of various cables by shortening the length of a power line and a signal cable connecting a motor. .
