Abstract

The invention discloses a sewage pump control circuit and relates to the technical field of electrical control equipment manufacturing. The sewage pump control circuit comprises a first manual pump circuit, a first automatic pump circuit, a first standby automatic pump circuit, a second manual pump circuit, a second automatic pump circuit and a second standby automatic pump circuit. The sewage pump control circuit can solve the problems that when one water pump breaks down, sewage can not be discharged in time, and consequently property loss is caused.

Description

technical field [0001] The invention relates to the technical field of electrical control equipment manufacturing, in particular to a sewage pump control circuit for switching between two sewage pumps. Background technique [0002] With the continuous development of urban construction, there are more and more communities, hospitals and schools where people live. At the same time, there are more and more underground parking lots, and the requirements for the sewage pumps of underground parking lots are getting higher and higher. It is getting higher and higher. At present, most of the sewage pump units in the underground parking lot are a set of sewage pump units controlled by a motor. If this set of sewage pump units fails, the sewage will not be discharged in time in case of heavy rain or rainstorm. If the car parked in the parking lot cannot be driven out of the parking lot in time, the car will be submerged in water, thereby causing property damage. Contents of the inve...
