Description
Technical field
This utility model belongs to field of mechanical technique, relates to a kind of water pump, particularly to a kind of frost-cracking-preventing self priming pump.
Background technology
The operation principle of self priming pump is: first fill water (or in pump case, self has water) in pump case before starting mode of pump.Current direction volute during impeller high speed rotating makes impeller conduit after startup, at this moment enters interruption-forming vacuum, makes to open into water non-return flap, and the air in suction tube enters in pump, and arrives outer rim through impeller conduit.Self priming pump belongs to self priming centrifugal pump, simple in construction little with its volume, easy to operate, operate steadily, safeguard easily, the advantage such as efficiency height, life-span length and be widely used in the fields such as family life water intaking, down-hole water intaking, tap water boosting, vegetable dish booth pouring.The each parts of pump head of existing self priming pump connect each via screw and structure is the firmest, and intake-outlet connects entirety impeller the most out of shape and stuck after hard tube, and when running into arctic weather, the pump housing is susceptible to bursting by freezing, causes unnecessary economic loss.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, it is provided that a kind of frost-cracking-preventing self priming pump preventing pump housing bursting by freezing.
The purpose of this utility model can be realized by following technical proposal: a kind of frost-cracking-preventing self priming pump, including motor and the pump housing that is connected with motor one end, it is provided with rosette on described motor, on the described pump housing, there is water inlet, outlet and liquid feeding mouth, described water inlet and outlet lay respectively at the both sides of the pump housing, described liquid feeding mouth is positioned at the top of the pump housing, it is characterized in that, the electrical heating wire being connected with pump body it is provided with inside the described pump housing, and described electrical heating wire is connected with rosette by two electric wires, it is positioned at place below liquid feeding mouth inside the described pump housing and is provided with the temperature/pressure sensor that can measure pump housing temperature and pressure size, and described temperature/pressure sensor is connected with rosette by electric wire.
In above-mentioned a kind of frost-cracking-preventing self priming pump, described pump housing top is provided with the level sensor being connected with pump body with liquid feeding mouth adjacent, and described level sensor is connected with rosette by electric wire.Level sensor can detect the water level in the pump housing at any time, and the water level being effectively prevented in the pump housing is too low.
In above-mentioned a kind of frost-cracking-preventing self priming pump, having the connection seat of outwardly convex inside the described pump housing, described connecting is provided with, on seat, the pressurized tank being connected with pump body.The setting of pressurized tank serves the effect of equilibrium water amount and pressure.
In above-mentioned a kind of frost-cracking-preventing self priming pump, the described seat that connects has the parcel wrapped up by electrical heating wire and for the tank connected threaded portion of pressure.
Compared with prior art, this frost-cracking-preventing self priming pump is provided with temperature/pressure sensor and electrical heating wire, and when temperature/pressure sensor senses pump body temperature less than certain value, electrical heating wire starts to heat the liquid in the pump housing, is effectively prevented the pump housing by bursting by freezing.
