Abstract
A kind of fast self-priming high efficient horizontal self priming pump the invention discloses air entry in front end, including pump shaft and the pump housing, the pump shaft left end is provided with impeller, the impeller right end is provided with partition, the partition right end is fixed with seal case by screw, is provided with accessory impeller between the seal case and partition；The pump shaft outer ring is provided with axle sleeve, and organic envelope is arranged in the axle sleeve outer ring.Beneficial effects of the present invention, first lead to machine seal cooling water, after open pump, self-priming can be realized in 10 seconds, the efficiency of pump almost as centrifugal pump of horizontal axis, increases this self-absorbing structure consumption power limited, 3KW is no more than for large-scale self priming pump, small-sized self priming pump consumption power is lower.Compared to self-sucking pot is installed additional before traditional ZB type horizontal self-sucking pump or centrifugal pump, this new construction is without filling pump, and faster, the efficiency of pump is higher for self-priming time.
Description
Technical field
The present invention relates to pump valve equipment technical fields, and in particular to a kind of fast self-priming high efficient horizontal of air entry in front end
Self priming pump.
Background technique
Horizontal self-sucking pump, the pattern pump compared with the self-priming centrifugal pump of other patterns, because pump itself does not have non-return valve, knot
Structure is the simplest；It works the most reliable；Time between failures are long, safeguard, is easy to use, small in size, light-weight, high-efficient,
Special consideration has been done in design compared with the pump of identical bore, and discharge capacity is big, performance is high.
Horizontal self-sucking pump is in industrial and agricultural production, relief of speedily carrying out rescue work, as being used as emergency pump effective utilization more prominent in water drainage, fire fighting
Out.The industrial departments cities such as the generally applicable petroleum of horizontal self-sucking pump, chemical industry, metallurgy, machinery, chemical fibre, food, the energy, traffic are given
Water also can be used for agricultural drainage and irrigation, sprinkling irrigation.For conveying less than 5 ° E of clear water or viscosity, temperature is lower than 80 DEG C of physics and chemical property class
Like other liquid of clear water.
Self-sucking pot is installed additional before existing ZB type horizontal self-sucking pump or centrifugal pump, and complicated for operation, self-priming time is long, self priming pump
Service efficiency cannot reach actual demand.
Summary of the invention
In view of the above-mentioned problems, the present invention is intended to provide a kind of air entry front end fast self-priming high efficient horizontal self priming pump.
To realize the technical purpose, the scheme of the invention is:
Preferably, a kind of fast self-priming high efficient horizontal self priming pump of air entry in front end, including pump shaft and the pump housing, feature exist
In: the pump shaft left end is provided with impeller, and the impeller right end is provided with partition, and the partition right end is solid by screw
Surely there is seal case, be provided with accessory impeller between the seal case and partition；The pump shaft outer ring is provided with axle sleeve, institute
Organic envelope is arranged in the axle sleeve outer ring stated.
Preferably, the seal case front end is provided with machine sealing flushing water out, the seal case rear end is set
It is equipped with high-voltage end outlet.
The air of suction chamber is compressed preferably, the accessory impeller forms water ring by rotation.
Preferably, the impeller surface annular is provided with several air entries, the air entry and partition are formed
Negative pressure.
Beneficial effects of the present invention, first lead to machine seal cooling water, after open pump, self-priming can be realized in 10 seconds, the efficiency of pump is almost
As centrifugal pump of horizontal axis, increases this self-absorbing structure consumption power limited, 3KW is no more than for large-scale self priming pump, it is small-sized
It is lower that self priming pump consumes power.Compared to self-sucking pot is installed additional before traditional ZB type horizontal self-sucking pump or centrifugal pump, this new construction is without filling
Pump, faster, the efficiency of pump is higher for self-priming time.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
The present invention is described in further details in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, specific embodiment of the present invention is
A kind of fast self-priming high efficient horizontal self priming pump of air entry in front end, including pump shaft 8 and the pump housing 1, it is characterised in that: described
8 left end of pump shaft be provided with impeller 2,2 right end of impeller is provided with partition 5, and 5 right end of partition is fixed by screw
There is seal case 7, is provided with accessory impeller 3 between the seal case 7 and partition 5；8 outer ring of pump shaft is provided with axle sleeve
4, organic envelope 9 is arranged in 4 outer ring of axle sleeve.
7 front end of seal case is provided with machine sealing flushing water out 7.1, and the seal case rear end is provided with height
Pressure side outlet 7.2.
The accessory impeller 3 forms water ring by rotation and compresses to the air of suction chamber.
The 2 surface annular of impeller is provided with several air entries 6, and the air entry 6 and partition 5 form negative pressure.
When specific implementation:
First lead to machine seal cooling water, after open pump, accessory impeller 3 rotates, and in partition 5 and the formation of air entry 6 negative pressure, (air entry 6 is preceding
End), 1 entrance air of the pump housing is sucked from 2 balance hole of impeller and is sealed from the machine sealing flushing water out 7.1 of seal case 7 outflow machine
Flushing water, machine sealing flushing water press the air in suction chamber because the rotation of accessory impeller 3 forms water ring in the intracavitary of seal case 7
Contracting, compressed air is from 7.2 discharge air of seal case cavity rear end high-voltage end outlet and water, until pump inlet pipeline and the pump housing
Middle air emptying is hydraulically full, completes self-priming process, machine seal cooling water is turned off after termination of pumping.
The above, only presently preferred embodiments of the present invention, are not intended to limit the invention, all skills according to the present invention
Art any trickle amendment, equivalent replacement and improvement substantially to the above embodiments, should be included in technical solution of the present invention
Protection scope within.
