Description

Electronic pressure water flow control pump

technical field

Background technique

At present, the methods of controlling the start and stop of water pumps on the market usually include float ball control water pumps and induction water level control water pumps. Among them, the float control water pump adopts the float in the form of electricity to control the start and stop of the water pump through the buoyancy of the water, as well as the control of the water level of the water pump. The disadvantage is that if the water level is lower than the floating height of the float ball, the water pump cannot work and requires personnel to remove the float ball. Only when the water level is fixed upright can the water pump start to work. If the water level is higher than the floating height of the floating ball, if the personnel need to leave temporarily during the working process, such as closing the valve at the water outlet, the machine will work under pressure and reduce the machine. service life, or unplug the power plug, the machine will stop working when the power is off, and when the personnel come back, they need to plug in the plug again. The operation is inflexible and inconvenient to use. Inductive water level control pumps are controlled by two or more water level sensing points. The disadvantage is that the distance between the water level points is small and easily affected by water waves, causing frequent start and stop.
