Abstract
The utility model relates to a protector against the water shortage of a water pump, which comprises a shell, a membrane sheet in a containing chamber in the shell and a spring attachment tightly pressed on the membrane sheet, wherein the shell is provided with a water inlet and a water outlet, the containing chamber is arranged between the water inlet and the water outlet, a piston which is provided with a piston magnet is arranged in the water inlet, a magnetic control element is arranged on a position which corresponds to the piston magnet, and the magnetic control element is connected with a control circuit. When a water pool or a water well is short of water, water discharge is reduced, and the water pump is caused to stop working through the control circuit. The utility model has the advantages of accurate control, no requirement of accessory installation under water, simple installation and wide sphere of application.
Description
Technical field
The utility model relates to pump part, particularly a kind of electronic auto-control device of water pump.
Background technique
Water pump is when draining, and the water in pond or well is taken out to the greatest extent, and water pump idle running is not only wasted electric energy, and made water pump pump chamber lack of water, needs water filling again, troublesome poeration when reusing.A kind of water level controller appears recently, utilize ball float perception water level, as Chinese patent 99236731.X disclosed " full-automatic water level controller ", be in the ball float of sealing steel ball, switch to be set, switch is drawn by electric wire, and one end of electric wire is fixed on the pool wall during use, when ball float rises or descend, ball float and horizontal angle of inclination change, and steel ball makes switch motion because action of gravity is slided, and realizes opening or closing.This device need be fixed on an end of electric wire on the pool wall, can't install in some wells, has limited use; In addition owing to influenced by the mounting point, be difficult for accurately being controlled at water and just take out and water pump is quit work when most.
Summary of the invention
The utility model purpose is to provide a kind of water pump water shortage protective device by water flow control, with the raising precise control, and makes its installation simple, applied widely.
Scheme of the present utility model is: this device comprises a housing with water intake and water outlet, be arranged on the diaphragm in the cavity volume between the intake-outlet in the housing and be pressed on spring attachment on the diaphragm, piston is set in the water outlet, piston is provided with piston magnet, be provided with the magnetic control element with piston magnet opposite position, the magnetic control element is connected with control circuit.
The utility model has the advantages that: owing in the water outlet piston is set, in the pond or during the well lack of water, water flow reduces, current reduce the thrust of piston, and piston falls after rise, and piston magnet is near the magnetic control element, to its effect, and water pump is quit work by control circuit.Advantage with precise control, and do not need installation accessories under water, install simple, applied widely.
