Background technique
Water pump is the machinery of carrying liquid or making the liquid supercharging, and water pump is widely used in daily life and industrial production, and existing water pump commonly used is Centrifugal water pump.One comprises impeller, motor and the pump housing Centrifugal water pump, and the output shaft of motor passes the pump housing and is connected with the impeller that is positioned at the pump housing.The working principle of Centrifugal water pump is as follows: the driven by motor vane rotary, the water intake of water from the pump housing sucked in the pump housing, and be displaced into the water outlet of the pump housing.Wherein active is impeller, the blade rotary of impeller, water is driven under centrifugal action to throw away to the inwall of the pump housing by blade again and flows out from water outlet, water in the pump housing is after throwing away, new current enter under atmospheric pressure in the pump housing again, and water continuously enters from water intake again and discharges from water outlet like this.But this water pump needs to fill first water in the pump housing before startup.If do not fill water, impeller can only drive the air rotation, because the per unit volume quality of air is very little, the centrifugal force that produces is just very little, and is unable with in the pump housing and the Bas Discharged in the water outlet, can not form vacuum in the pump housing, water also just can not suck, and water pump can't work.
Generally speaking, to adding water in the water pump, all realize by offering the filler, when water pump is poured water operation, because operator's error can cause the water spilling to motor, motor is got rusty, affect working life; And when the water spilling is to the motor, can cause the short circuit of circuit, cause the generation of security incident.After adding water, for guaranteeing the tightness in the water pump, the place has additional plug in the filler.But plug of the prior art is connected with the filler for making things convenient for it, long shank is set conveniently screwing in its end, but shank is exposed to the outside of water outlet, often bumps with the external world and causes shank to damage, and after the shank damage, is inconvenient to screw plug.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, proposed a kind of reasonable in design water pump add water-bound.
The purpose of this utility model can realize by following technical proposal:
This water pump add water-bound, the outlet pipe of water pump comprises the vertical tube that directly is communicated with the water pump inner chamber and is located at transverse tube this riser upper portions and that be communicated with this vertical tube, it is characterized in that, the described water-bound that adds comprises the filler of being located at transverse tube top and the pipe plug of being located in the filler, described filler is over against the vertical tube setting, the top of described transverse tube also is provided with dash curtain in the form of a ring, and described filler is positioned at this dash curtain.
When needs add water to water pump, open pipe plug, this moment, the inner chamber of water pump was in communication with the outside by family and the mouth of a river, and water is added in the water pump inner chamber in the filler, when water is added to certain value, closed the filler with pipe plug.In whole process, the dash curtain is prevented sealing spilling, the working life of having improved motor.
In adding in the water-bound of above-mentioned water pump, described pipe plug comprises that the joint that is inserted in the filler and its inner side surface of being located at the joint outer end are resisted against the head on the transverse tube, described filler is provided with outside thread, have the internal thread that matches with this outside thread in the described filler, the outer side surface of described head is provided with mounting groove.
After the joint with pipe plug partly screws in to the filler, can't continue to rotate pipe plug, need instrument to be inserted in the mounting groove this moment, further screws in to the filler by pulling tool and then with joint, behind the tool using, time saving and energy saving.Because mounting groove inwardly concaves, and is positioned at the dash curtain, can not bump with the external world, has guaranteed the stability of pipe plug, has improved the working life of this pipe plug.
In adding in the water-bound of above-mentioned water pump, described mounting groove is two: mounting groove one and mounting groove two, and described mounting groove one and mounting groove two square crossing settings, described mounting groove one is positioned on the medial axis of described head with the point of intersection of mounting groove two.
In adding in the water-bound of above-mentioned water pump, the edge of described mounting groove one and mounting groove two forms 4 and outwards outstandingly is fan-shaped stop part, is respectively equipped with the fan-shaped cavity that inwardly concaves on the described stop part.This cavity is set, can saves the application to material, reduce manufacture cost.
In adding in the water-bound of above-mentioned water pump, have the annular recess that arranges around above-mentioned joint on the inner side surface of described head, described outside thread extends in this annular recess.This annular recess is tool withdrawal groove, and is convenient to externally threaded processing on the joint.
Compared with prior art, the water-bound that adds of this water pump has the following advantages:
Be provided with the dash curtain at transverse tube, when the water pump inner chamber is added water, water can spilling to motor, effectively prolonged the working life of motor; Because mounting groove inwardly concaves, and is positioned at the dash curtain, can not bump with the external world, has guaranteed the stability of pipe plug, has improved the working life of this pipe plug; Inner side surface at head is provided with annular groove, and this groove is tool withdrawal groove, and is convenient to externally threaded processing on the joint; Pipe plug is connected with the filler by screw thread, and linkage structure is solid and reliable, good stability.
