Description

Antifreeze water pump

One, technical field

The utility model relates to a kind of water pump, relates in particular to the antifreeze water pump of a kind of family expenses.

Two, background technique

Present family expenses small-power water pump (below 2000 watts) is made up of the pump housing, drive motor, mechanical seal three parts such as self-priming centrifugal water pump, small-sized screw pump etc., these water pumps can draw water from the well of degree of depth 10m-50m, water lift in the well in extensive use low water level area, domestic water, also be specially adapted to building water supply, small-sized field irrigation, use easily.But, the household small-size water pump does not possess antifreeze function now, especially at cold night in winter, when temperature is lower than subzero, the surplus water that water pump is retained will freeze in the pump housing, causes pump to start, even startup can be burnt the motor lines bag under the situation of freezing, the damage water pump influences people and lives normally.

Three, summary of the invention

The purpose of this utility model is in order to overcome the deficiencies in the prior art, provides a kind of and can effectively prevent to freeze in the pump housing, high insulating effect, the antifreeze water pump that can normally start in cold winter.

The technological scheme that the utility model is taked: it comprises motor, the pump housing, and pump housing outside is provided with shell, is filled with thermal insulation layer in the space between the shell and the pump housing.

For ease of dismounting and maintenance water pump and raising water pump resistance to frost, shell is formed by left and right two housing sections butt joint, left shell is located at outside the pump connection of the pump housing, and left shell and pump are provided with the polyurethane foam thermal insulation layer and are bonded as a little single piece by the polyurethane foam thermal insulation layer between connecting; Right shell body is located at outside the pump head of the pump housing, is provided with the polyurethane foam thermal insulation layer between right shell body and the pump head and is bonded to a big single piece by the polyurethane foam thermal insulation layer; Little single piece is provided with screw hole, and described screw hole is corresponding with the attachment screw position that pump connects upward installation, and little single piece is fixedlyed connected by attachment screw with big single piece, is provided with rubber stopper seal in the screw hole.

In order not only to save material but also to guarantee better heat insulation effect, the thickness of polyurethane foam thermal insulation layer is between 2.5-10cm.

In order to strengthen sealability, more effective cool air that prevents enters, and is provided with a gasket seal in little single piece and big single piece joint.

Good effect of the present utility model is: simple in structure, set up shell and thermal insulation layer on the basis of existing water pump, easy processing, cost is low, and antifreezing effect is good and lasting, can solve water pump problem because of freezing and starting under sub-zero environment, prevent to damage water pump; Adopt left and right two-part shell and polyurethane foam thermal insulation layer that pump housing integral body is fixed to large and small single piece, dismounting is easy for installation, quick, good integrity, intensity height, resident's use easy to use, as needing can be widely used in water supply.

Five, embodiment

As shown in Figure 1, the utility model is to have additional shell 12 in the pump housing 10 outsides of existing water pump, shell 12 is anti-aging, impact-resistant rigidity thin-shell construction, can adopt steel, aluminium or high molecule plastic to make, the structure of the pump housing 10 belongs to prior art, and it is connected 3 by pump head 7 with pump and forms, and pump connection 3 is connected to form by electric motor end cap, connection gusset, pump end cap, connect gusset one end and connect electric motor end cap, the other end connects the pump end cap.

Be dismounting easily, maintenance water pump, shell 12 is formed by left shell 4, the butt joint of right shell body 8 two-part, as Fig. 1, Fig. 2, shown in Figure 3, left shell 4 is located at pump and connects 3 outsides, left shell 4 and pump are provided with thermal insulation layer 6 between connecting 3, for guaranteeing certain intensity and rigidity, this thermal insulation layer 6 adopts whole typing polyurethane foam thermal insulation layer 5, owing to have very strong cohesive property behind the polyurethane foam, can make left shell 4, pump connection 3, polyurethane foam thermal insulation layer 5 threes be bonded as a little single piece 17, be provided with motor output shaft hole 2 on the polyurethane foam thermal insulation layer 5 in left shell 4.

As Fig. 1, Fig. 4, shown in Figure 5, right shell body 8 is located at outside the pump head 7 of the pump housing 10, is provided with polyurethane foam thermal insulation layer 5 between right shell body 8 and the pump head 7, and right shell body 8, pump head 7, polyurethane foam thermal insulation layer 5 threes are bonded to a big single piece 18; The right shell body 8 of big single piece 18 and the polyurethane foam thermal insulation layer 5 of Qi Nei are provided with water inlet pipe mouth 9 and effluent pipe mouth 11.

In order not only to save material but also to guarantee better heat insulation effect, the thickness of above-mentioned polyurethane foam thermal insulation layer 5 is between 2.5-10cm.

Existing pump connects on four jiaos of 3 the pump end caps and respectively is provided with a silk hole, an attachment screw 14 that is used to connect pump connection 3 and pump head 7 is installed in each hole, be easy disassembly, gather materials on the spot, as shown in Figure 1, little single piece 17 can be fixedlyed connected by this attachment screw 14 with big single piece 18, offer four screw holes 15 on the left shell 4 of little single piece 17 and the polyurethane foam thermal insulation layer 5 of Qi Nei, screw hole 15 is corresponding with the position of attachment screw 14, after installing attachment screw 14, in screw hole 15, fill in and be used to the rubber stopper 16 that prevents that cool air from entering.In order to strengthen sealability, more effective cool air that prevents enters, and is provided with gasket seal 13 as shown in Figure 1 between two interfaces of little single piece 17, big single piece 18.

Polyurethane foam thermal insulation layer 5 of the present utility model is refrigeration, field of thermal insulation prior art, and its integral foam preparation process the those skilled in the art all can design and make, and no longer describes in detail here.
