Description

Multifunctional water pump

The utility model relates to a kind of multifunctional water pump, belongs to the blade type water pump.

Present employed submersible pump mainly is made of motor tube, motor stator, rotor, motor shaft, water inlet joint, impeller and pump head etc., the driven by motor wheel rotation, under the effect of impeller, water enters impeller through the water intake of water inlet joint and the mouth of a river of leading to impeller on its end wall, and is dumped into pump head and outlet pipe.Because the pump housing and the power section of submersible pump are connected as a single entity, thus it be convenient to move and carry, easy to use; Simultaneously owing to working in the pump housing and the whole potential water of motor, so can solve the heat dissipation problem of motor naturally.The shortcoming of submersible pump is: 1, can not be with the operation of drawing water of other on-electric power under the situation of not having electricity; 2, in the area of shallow water area and needs use centrifugal pump, can not more than the water surface, use.Though present employed centrifugal pump can be worked more than the water surface with other dynamic power machine as power source, it is less that it inhales journey, simultaneously since its pump housing and power section be separated, so install and move very trouble, be unfavorable for mobile operating, use inconvenient.

Therefore the purpose of this utility model is that existing submersible pump is improved, and a kind of new multifunctional water pump is provided, and this water pump both can be made submersible pump, can make centrifugal pump again.

The purpose of model utility realizes by following mode.

Multifunctional water pump, comprise motor tube, motor stator, rotor, motor shaft, water inlet joint, impeller and pump head, an end wall of water inlet joint is provided with the mouth of a river of leading to impeller, another end wall is provided with the mouth of a river of leading to the motor tube inner chamber, the perisporium of water inlet joint except that leaving water intake, all the other sealings.

When using as submersible pump, water is inhaled into into water joint from the water intake of water inlet joint, and one tunnel the mouth of a river through leading to impeller enters the suction inlet of impeller, is thrown away by impeller, by the snail direction of flow water output connector of pump head again; Another road then enters the motor tube inner chamber by the mouth of a river of leading to the motor tube, and the heat that is distributed when utilizing machine operation carries out cold and hot convection circulation, thereby plays the effect of heat radiation.When working more than the water surface as centrifugal pump, the water intake of water inlet joint should connect intake pipe and halter down, should pour water in the water pump chamber in advance as treating Ordinary Centrifugal Pumps simultaneously, and its working principle is the same with submersible pump.That is to say that the work or work of no matter pulling the plug particularly always has water in circulation around the rotor of motor tube inner chamber in the pump body, can reach the purpose of heat radiation, has overcome the shortcoming that submersible pump can not be worked more than the water surface more than the water surface.Because this water pump can work more than the water surface, thus also can be with other on-electric power machinery as diesel engine etc. as the power operation of drawing water, need only add that on-electric power drive wheel gets final product.Owing to solved the heat dissipation problem of motor when water pump is worked more than the water surface,, can utilize other on-electric power machinery to generate electricity if be equipped with cooling water tank and power distribution unit.The great advantage of the multifunctional water pump that the utility model provides is, this water pump both can be used as submersible pump, can be used as centrifugal pump again, and the work that both can pull the plug can be worked more than the water surface again.Simultaneously can also use other on-electric power to carry out operation, can also generate electricity.Therefore this water pump is not subjected to the influence of area and power supply situation, it is in office that where distinguish and do not have under the electric situation can proper functioning and use, and can reduce and avoid the overlapping investment of agricultural production aspect, the price of using logical submersible pump of a Daepori or the logical centrifugal pump of a Daepori to add a motor can reach the effect that existing centrifugal pump has submersible pump again, can also carry out on-electric power and draw water and generate electricity.The advantage of the existing submersible pump of this multifunctional water pump has the strong point of centrifugal pump again, and structure is ingenious simple, and cost is low, is specially adapted to the agricultural production under the various conditions.

Below in conjunction with accompanying drawing the utility model is described in detail.

Accompanying drawing 1 is the structural representation of the multifunctional water pump that provides according to the utility model, and accompanying drawing 2 and 3 is respectively the cross sectional view and the longitudinal section diagrammatic sketch of water inlet joint in the accompanying drawing 1, and attached Figure 4 and 5 are respectively the cross sectional view and the longitudinal section diagrammatic sketch of motor tube in the accompanying drawing 1.(cross section refers to the cross section parallel with motor shaft, and the longitudinal section refers to the cross section vertical with motor shaft)

Multifunctional water pump comprises water output connector (1) as shown in drawings, nut (2), rubber sheet gasket (3), bolt (4), pump head, (5), impeller gland nut (6), packing ring (7), impeller (8), rubber seal (9), (14), (15), (25), (27) and (30), water inlet joint (10), water seal (11), (12), (17), (18), (24), (26), (32) and (33), upper bearing (metal) (13), last water gland (16), motor windings (19), motor shaft (20), stator (21), motor tube (22), rotor (23), lower end cap (28), lower bearing (29), following water gland (31), on-electric power drive wheel (34), transmission wheel cover (35).Multifunctional water pump as shown in drawings, mainly comprise motor tube (22), motor stator (21), rotor (23), motor shaft (20), water inlet joint (10), impeller (8) and pump head (5), an end wall of water inlet joint is provided with the mouth of a river (36) of leading to impeller, another end wall is provided with the mouth of a river (38) of leading to the motor tube inner chamber, the perisporium of water inlet joint except that leaving water intake (37), all the other sealings.
