Abstract

The invention discloses a stable submersible pump control switch. A cylindrical groove-shaped water containing groove is formed in a control column; a round-hole-shaped water inlet hole with an upward opening is formed in the upper side wall of the water containing tank; a pressure sensor is arranged on the bottom surface of the water containing tank; a pressing plate is vertically, elastically and movably arranged at the lower part of the water containing tank; the pressing plate and the cylindrical surface of the water containing tank are in sealed sliding arrangement; a cylindrical groove-shaped lower water groove is formed in the lower end surface of the control column; a plurality of U-shaped water flowing pipes which are circumferentially and uniformly distributed and are provided with inward openings are formed at the lower part of the side wall of the water containing tank; a plurality of lower water inlet holes with radial openings are circumferentially and uniformly distributed in the middle of the side wall of the lower supporting cylinder; floating plates are vertically and movably arranged at the left end and the right end of the lower supporting cylinder respectively; a vertical connecting rod is fixed on the upper end surface of the floating plate; a plug is formed at the upper end of the vertical connecting rod.

Description

technical field [0001] The invention relates to the technical field of water pump control switches, in particular to a stable submersible pump control switch. Background technique [0002] Submersible pumps are important equipment for drainage operations and are widely used in various industries. Since the submersible pump is used to submerge the whole pump into the water to work, an automatic switch is generally used, which controls the switch of the submersible pump by detecting the water level, and automatically shuts down when the water level drops to a certain lower limit. Most traditional submersible pumps use a float switch, but the float switch is connected to the submersible pump through a hose, which is prone to external interference. In the case of a narrow location, the float switch is easily interfered and cannot operate normally, causing the float switch to control the water pump. Misoperation, inability to start and stop the submersible pump, etc. SUMMARY O...
