It is characterized in that: the inner end of motor end cover (4) has a bearing base (14) which contains a bearing (9); the inner ring of bearing (9) is fixed on the motor axle (15) which contains several rotation induction chambers (1) in screw shape; the outer end of motor end cover (4) has screw oil seal base (2) which is connected to the end cover inner screw (13) via screw; the screw oil seal base (2) contains the oil seal (10); the oil seal (1) and the motor axle (15) are designed by mechanical sealing structure; the outer end of motor end cover (4) is mounted with external screw (3) which matches the locking nut (16) to fix and the external connecting elements of liquid inlet and outlet. The invention can be used in ground and underwater projects.
Description
Technical field: the present invention relates to a kind of interior spiral pump of motor shaft simple, low production cost of making.
Background technique: at present the liquid pump of domestic and international all kinds of models adopt on the pump shaft or motor shaft impeller is installed on conjuncted, liquid is thrown away its parabolic type by the impeller rotation, to its work done, its manufacturing process complexity, and also volume is big, cost is high, function singleness.
Summary of the invention: for a change above-mentioned technological deficiency, it is simple to the invention discloses a kind of manufacturing process, the interior spiral pump of motor shaft of low production cost.
Mode of execution: for achieving the above object, the present invention adopts following technical proposal:
Described interior spiral pump of motor shaft, inhale cavity (1), connect screw thread (3) outward by revolving, electric motor end cap (4) bearing (9), oil sealing (10), end cap internal thread (13), bearing support (14), motor shaft (15), locking nut (16) is formed.It is characterized in that: the inner of electric motor end cap (4) is provided with bearing support (14), and bearing (9) is installed in the bearing support (14), and bearing (9) inner ring is fixed on the motor shaft (15).Be provided with 1-9 in its motor shaft (15) and revolve suction cavity (1), also be provided with spiral oil sealing base (2) on its electric motor end cap (4), connect screw thread (3) outward, end cap internal thread (13).
The helicoid shaft inward turning suction structure that cavity (1) the present invention adopts a kind of uniqueness is inhaled in revolving of its described motor shaft, uses metallic material, or forms through metallic material, stainless steel material and the nonmetallic material manufacturing of antiseptic and rustproof special processing.
The inner of its described end cap internal thread (13) spins and is fixed with spiral oil sealing base (2), and oil sealing (10) is installed in the spiral oil sealing base (2), and oil sealing (10) adopts the mechanical seal structure design with motor shaft (15).
Outer end and locking nut (16) that its described outer connection screw thread (3) is located at electric motor end cap (4) are used, and are used for fixing the outer coupling member of liquid inlet and outlet.
Its described locking nut (16) outer end of the present invention is the metalwork or the non-metal part of shape or hand-screw type in many ways.
The drawing explanation: figure one is the structural representation of interior spiral pump of motor shaft;
Figure two is that revolving of interior spiral pump of motor shaft inhaled the cavity cross sectional representation;
As shown in the figure: (1) revolves the suction cavity among the figure, (2) spiral oil sealing base, (3) outer screw thread that connects, (4) electric motor end cap, (5) motor stator, (6) rotor, (7) motor housing, (8) motor drop hanger, (9) bearing, (10) oil sealing, (11) liquid outlet, (12) base, (13) end cap internal thread, (14) bearing support, (15) motor shaft, (16) locking nut.
Embodiment: the present invention as shown in FIG.: liquid by outer connection screw thread (3) and locking nut (16) fixing seal after electric motor end cap (4) motor stator (5) heat loss through conduction is cooled off, entering revolving of motor shaft (15) then inhales in the cavity (1), by motor shaft (15) it is rotated work done, liquid, cools off after the electric motor end cap of liquid outlet (4) dispels the heat to motor stator (5) once more rotor (6) heat radiation cooling by motor shaft (15) during this period.At last with the liquid after the work done in liquid outlet (11) is threaded to the outer coupling member of liquid outlet.Thereby saved the heat radiation fan blade of motor, the fan blade guard shield and is now compared with the pump series products, has saved belt pulley, water pump pulley (or coupling), pump shaft, bearing, impeller, pump volute body and the mounted pump of motor, the parts such as heavy base that motor is used.Thereby make its volume-diminished, weight saving, reduce production costs about 50%, and save electric power energy more than 30%.
Project organization of the present invention is simple, low production cost, move and use all very convenient, and can be used under ground, the liquid, multi-mode operation such as diving, be renewal and the update product of now using the liquid pump class, tool is by vast market prospect.
