Description
Technical field
The utility model relates to centrifugal pump technical field, relates in particular to a kind of solar water heater recycle pump.
Background technique
The basic structure of centrifugal water pump comprises motor, impeller, the pump housing, water intake and water outlet, water intake is connected with intake pipe, centrifugal water pump starts before action, the pump housing and intake pipe need to be filled water, discharge air, after starting mode of pump, driven by motor wheel rotation, at impeller high-speed rotary then under the effect of the centrifugal force producing, water in impeller channel is thrown out of water outlet, near space water intake forms vacuum, and water source is pressed in the pump housing along intake pipe under external atmospheric pressure, and bulged-in water is got rid of into outlet pipe by impeller again then.As can be seen here, in order to guarantee that centrifugal water pump works safely and efficiently, need to keep vacuum state in the pump housing, once entrained air, the inside and outside pressure difference of the pump housing is not enough to hydraulic pressure to enter in the pump housing, causes water pump " deadlock ", cannot be again from the normal water outlet of water outlet; Air is sneaked in water, forms bubble and contacts with the impeller of rotation, and therefore impeller shaft dallies and cause burning out.
In order to prevent that air from entering in water pump, generally can seal ring be set and filler seals the pump housing, but along with the infiltration of the aging and air of seal ring, the time one is long, just cannot continue to keep vacuum state in the pump housing; Therefore generally all venting gas appliance can be set on centrifugal water pump; The existing exhaust scheme for centrifugal water pump is all not satisfactory, not only complex structure, operation inconvenience, and long, the exhaust of period of exhaust is not thoroughly worse, the short time can repeatedly exhaust, cannot reach good exhaust effect all the time.
As can be seen here, although know in the pump housing and pour into the harm that air brings be also no lack of the deaeration for how perfectly well, keep the conceptual design of pump chamber degree of vacuum, but impeller shaft is damaged because of idle running, and the problem that water-outlet quantity is little still occurs in the using process of existing centrifugal water pump often.
Model utility content
The technical problems to be solved in the utility model is: in order to solve the exhauster structure complexity on existing centrifugal water pump, and the problem that exhaust effect is poor, the utility model provides a kind of solar water heater recycle pump to solve the problems referred to above.
The utility model solves the technological scheme that its technical problem adopts: a kind of solar water heater recycle pump, comprise the pump housing, motor, rotatingshaft, impeller and motor casing, described motor is fixed in motor casing, described rotatingshaft one end is connected with motor, motor casing is extended in one end in addition and impeller is fixed, described motor casing and the pump housing are fixedly connected to form pump chamber, described impeller is arranged in pump chamber, on the described pump housing, offer the exhaust port that is communicated with space outerpace and pump chamber, in described exhaust port, be provided with venting gas appliance, described venting gas appliance comprises air exhaust rod and Sealing, described air exhaust rod has inlet end and outlet side, between the end face of described inlet end and the end face of outlet side, offer through hole, described inlet end is communicated with exhaust port, described Sealing is arranged on outlet side, valve as the opening of described through hole on the end face of outlet side.
Preferred Placement: described inlet end offers an outside thread, described inlet end and exhaust port screw thread are fixed.
Described Sealing is connected with outlet side by link, thereby by link being applied to the position relationship that active force changes Sealing and opening, reaches the object that opens and closes opening.
Described link is spring, described Sealing is threaded stem, and described outlet side offers outside thread, and the two ends of described spring screw in respectively in the thread groove of Sealing and the thread groove of outlet side, spring has elastic deformability, and external force just can change the relative position of Sealing and opening a little; Spring deformation number of times is too much, can reduce elastic deformability, thereby Sealing decreases for the sealing of outlet side, screw thread on Sealing and the effect of the screw thread on outlet side are exactly when there is above-mentioned situation, spring is rethought in thread groove and screws in a little, keep Sealing to the enough active forces in outlet side, thereby keep good sealing effect.
Described link is the rubber pipe with elastic deformability, described Sealing and outlet side are cylindrical bar, described rubber tube terminal is attached to Sealing and outlet side, on described rubber pipe, edge circumferentially offers out air cleft, the effect that engages to reach sealed open of Sealing itself and outlet side, and rubber pipe is without under External Force Acting, two ends brace Sealing and outlet side and air cleft and close, reached the effect of double seal, by the Placement of rubber pipe, also reduce Sealing and outlet side for the complex structure degree of the part that is connected, change also very convenient.
In order to improve outlet side and Sealing degree of adaptability structurally, the end face of described outlet side is concave surface, described Sealing has the convex surface with concave surface sealing laminating, because the reset of Sealing after venting is mainly to realize by the restoring force of link, therefore utilize coordinating of concave surface and convex surface, in the situation that not needing manpower, Sealing can accurately return best sealing station, guarantees sealing.
In order to increase exhaust efficiency, described through hole is divided into first paragraph and second segment, and described first paragraph is near inlet end and be shaped as cylindrical body, and described second segment is near outlet side and be shaped as cylindrical body, described first paragraph through long for second segment through long 1.3～1.7 times.
According to the general mounting point of centrifugal water pump, the described pump housing comprises the drain pipe that pump chamber is threaded with external pipe, and described exhaust port is opened on drain pipe.
Further, the described pump housing also comprises the liquid inlet pipe that pump chamber is communicated with external pipe, point-blank, the central axes of described exhaust port is in the central shaft of liquid inlet pipe and have intersection point with the central shaft of drain pipe for the central shaft of described liquid inlet pipe and the central shaft of rotatingshaft.
The beneficial effects of the utility model are, for the water pump being applied in solar water heater, the pump housing simple in structure, pump chamber space is less, in pump chamber, the probability of entrained air is little, the amount of the required discharge air of venting gas appliance is very limited so, based on above-mentioned actual conditions, design the venting gas appliance of this solar water heater recycle pump, exhauster structure is simply ingenious, easy operating, help the time saving and energy saving Exhaust Gas of user, solve the not smooth problem of water outlet, outlet valve with respect to existing structure complexity, greatly reduce the cost of production of centrifugal water pump, improved the market competitiveness, in addition, exhaust port is directly opened on the pump housing, near impeller, timely and effectively by near the Bas Discharged impeller of harmfulness maximum, the use impression of the water heater bringing after exhaust significantly improves, and an exhaust can make water-outlet quantity remain in a long time normal stable.
