The utility model has good integrity for the buoy is disposed in the cylinder, the needed water level of control is reached for the delay motion of the electromotor switch of the water pump is realized by the equilibrium of forces between the buoy and magnetic components, the utility model has simple structure and need only a few components, thereby the operation is reliable, the service time is long, and the manufacture cost is low.
Description
Technical field
The utility model belongs to water-level control apparatus, is specifically related to a kind of floating drum that utilizes and controls the water level controller that water pump is opened.
Background technology
The existing floating drum that utilizes is controlled the water level controller that water pump is opened, no matter be mechanical type or electronic type, all exists structure complicated, and globality is relatively poor, and reliability is bad, and serviceable life is not long, the production cost problem of higher.
The utility model content
The purpose of this utility model is the deficiency at above-mentioned existing water level controller, provides a kind of simple in structure, good integrity, good reliability, the water level controller that production cost is low.
Realize that the technical scheme that the utility model purpose adopts is: water level controller comprises a cylindrical shell, floating drum is housed in the cylindrical shell, on cylindrical shell, be provided with switch fixed contact parts, floating drum is provided with switch moving contact parts and forms the moving assembly of switch, switch fixed contact parts and switch moving contact parts are formed the pump motor switch, are respectively equipped with switch moving contact parts are in disconnect with switch fixed contact parts or the corresponding elements of magnetic material of closure state on moving assembly of switch and cylindrical shell.
Principle of work: the utility model water level controller is fixed in the pond, during water-filling, switch fixed contact parts and switch moving contact parts are in closure state, and the mutual adhesive of elements of magnetic material on moving assembly of switch and the cylindrical shell, along with water level increases, the buoyancy that floating drum is subjected to increases, when buoyancy during greater than the mutual magnetic force between the adhesive elements of magnetic material, floating drum drive switch moving contact parts move upward and break away from switch fixed contact parts, the elements of magnetic material on the moving assembly of while switch and the off-state of the mutual adhesive maintained switch of another elements of magnetic material moving contact parts on the cylindrical shell, at this moment pump motor outage quits work, and water level reaches desired height; During water, water level descends gradually, the buoyancy that floating drum is subjected to reduces, when the little self gravitation to floating drum of buoyancy can overcome magnetic force between the elements of magnetic material of mutual adhesive, floating drum will drive switch moving contact parts and move downward again and contact with switch fixed contact parts, connect the automatic water-filling of pump motor, in this position, elements of magnetic material adhesive mutually again on moving assembly of switch and the cylindrical shell, the reliable contact between the maintained switch contact element.
Moving contact parts on the moving assembly of switch all utilize elements of magnetic material to locate in disconnection or closure state, and disconnect or closed transfer process in then be cause the variation of the suffered buoyancy of floating drum when utilizing SEA LEVEL VARIATION and self gravitation is broken and elements of magnetic material between the equilibrium relation of magnetic force, breaking of this equilibrium relation has a deferring procedure, it is the amplitude range of SEA LEVEL VARIATION, adjust the relative distance between the elements of magnetic material, just can regulate the amplitude range of SEA LEVEL VARIATION.
Further technical scheme is:
One end of described moving contact parts is hinged on the cylindrical shell, and it is reliably contacted better with switch fixed contact parts;
Elements of magnetic material on the moving assembly of described switch is located on the switch moving contact parts, and corresponding elements of magnetic material is located at the above and below of switch moving contact parts on the cylindrical shell;
Elements of magnetic material on the moving assembly of described switch is located at the top and bottom of floating drum, and corresponding elements of magnetic material is located at the top of floating drum upper end and the below of floating drum lower end respectively on the cylindrical shell.
The utility model has globality preferably because floating drum is contained in the cylindrical shell.Again owing to be to utilize between floating drum and the elements of magnetic material equilibrium of forces to realize the delay voltage of pump motor switch, and then reach the requirement of the required water level of control, structurally very tube is single, it is required that parts are few in addition, therefore work is very reliable, and prolong serviceable life, and production cost reduces.
Further specify the technical solution of the utility model below in conjunction with accompanying drawing.
