This scheme provides a horizontal self -priming centrifugal pump, realizes quick convenient blowdown through setting up the drain, has guaranteed the normal operating of water pump.
Description
Technical field
The utility model relates to a kind of horizontal self-suction centrifugal pump, belongs to water pump field.
Background technique
Horizontal self-suction centrifugal pump in industrial and agricultural production, relief of speedily carrying out rescue work, as water drainage, fire fighting in more outstanding as emergencypump effective utilization.But the impurities in liquid content drawn due to it is more, if discharge impurity not in time, easily causes impurity buildups in pump chamber too much to affect water pump operation.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of horizontal self-suction centrifugal pump, realizing blowdown quickly and easily, ensure that the normal operation of water pump by arranging sewage draining exit.
For achieving the above object, the utility model provides following technological scheme: a kind of horizontal self-suction centrifugal pump, comprise the pump housing, the pump housing is provided with into water chamber and water drain cavity, and separated by impeller between water inlet chamber and water drain cavity, the sidewall of described water inlet chamber is provided with side direction sewage draining exit, the shutoff of side direction sewage draining exit has side cover, the diapire of water inlet chamber is provided with bottom surface sewage draining exit, and bottom surface sewage draining exit shutoff has bottom, and described side cover and bottom removably connect with the pump housing respectively.
Preferably, described side cover and bottom respectively by screw fastening on the pump housing.
Preferably, between described side cover and the pump housing, be combined with seal ring, between described bottom and the pump housing, be combined with seal ring.
Preferably, described impeller is connected with transmission shaft, and transmission shaft is arranged with bearing, is provided with mechanical sealing assembly between bearing and impeller, and mechanical sealing assembly coordinates the isolation realizing bearing and impeller with the pump housing.
Preferably, the described pump housing is provided with bearing chamber, and described bearing is fixed on bearing bore indoor, and bearing chamber sidewall offers pouring orifice.
By adopting technique scheme, because most impurities is all deposited in water-inlet cavity indoor, affect the running of impeller, side direction sewage draining exit can be opened when water pump is normally placed, carry out blowdown process, bottom surface sewage draining exit being set in bottom simultaneously, can further clearing up the spot be deposited in into water cavity bottom when carrying out large repairs to water pump.The best area of side direction sewage draining exit is offered a little louder, conveniently takes out the large volume such as garbage bag, stone foreign matter, and bottom surface sewage draining exit opposite side diminishes to sewage draining exit area, avoids because opening causes too greatly that leakage rate is excessive affects pumping drainage efficiency.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural drawing of the present utility model;
Fig. 2 is the utility model side view;
Fig. 3 is the enlarged view at A place in the utility model Fig. 1.
Accompanying drawing illustrates: 1, the pump housing; 2, water inlet chamber; 3, water drain cavity; 4, side cover; 4a, side direction sewage draining exit; 5, bottom; 5a, bottom surface sewage draining exit; 6, seal ring; 7, transmission shaft; 8, pouring orifice; 9, bearing; 9a, bearing chamber; 10, stationary ring; 11, rotating ring; 12, impeller.
Embodiment
A kind of horizontal self-suction centrifugal pump, comprise the pump housing 1, the pump housing 1 is provided with into water chamber 2 and water drain cavity 3, separated by impeller 12 between water inlet chamber 2 and water drain cavity 3, the sidewall of described water inlet chamber 2 is provided with side direction sewage draining exit 4a, and side direction sewage draining exit 4a shutoff has side cover 4, and the diapire of water inlet chamber 2 is provided with bottom surface sewage draining exit 5a, bottom surface sewage draining exit 5a shutoff has bottom 5, and described side cover 4 removably connects with the pump housing 1 respectively with bottom 5.Because most impurities is all deposited in in water chamber 2, affect the running of impeller 12, side direction sewage draining exit 4a can open when water pump is normally placed, carry out blowdown process, bottom surface sewage draining exit 5a being set in bottom simultaneously, can further clearing up the spot be deposited in into bottom water chamber 2 when carrying out large repairs to water pump.The best area of side direction sewage draining exit 4a is offered a little louder, conveniently takes out the large volume such as garbage bag, stone foreign matter, and bottom surface sewage draining exit 5a opposite side diminishes to sewage draining exit 4a area, avoids because opening causes too greatly that leakage rate is excessive affects pumping drainage efficiency.
Wherein, side cover 4 and bottom 5 respectively by screw fastening on the pump housing 1.Adopt the mounting type of screw to coordinate fastening, convenient disassembly, can realize rapid pollution discharging.
Wherein, between side cover 4 and the pump housing 1, be combined with seal ring 6, between bottom 5 and the pump housing 1, be combined with seal ring 6.Arrange that seal ring 6 can be avoided into the liquid of water chamber 2 from side cover 4, let out bottom 5 and the pump housing 1 directly gap, affect the drainage efficiency of water pump.
Wherein, impeller 12 is connected with transmission shaft 7, transmission shaft 7 is arranged with bearing 9, is provided with mechanical sealing assembly between bearing 9 and impeller 12, and mechanical sealing assembly coordinates the isolation realizing bearing 9 and impeller 12 with the pump housing 1.Mechanical seal has leakage rate few and life-span and the advantage such as to grow, this mechanical sealing assembly is made up of rotating ring 11 and stationary ring 10 two-part, stationary ring 10 is fixed by screws on the pump housing 1, stationary ring 10 is provided with through hole and passes for transmission shaft 7, through hole is provided with depressed part with one heart, and rotating ring 11 to be fixed on transmission shaft 7 and to coordinate the function realizing mechanical seal with depressed part.
Wherein, the pump housing 1 is provided with bearing chamber 9a, and bearing 9 is fixed in bearing chamber 9a, and bearing chamber 9a sidewall offers pouring orifice 8.Bearing 9 major function is supported mechanical solid of rotation, reduces the friction factor in its movement process, therefore must ensure that it lubricates fully, by arranging pouring orifice 8 at bearing chamber 9a, conveniently irregularly lubricate to internal bearings 9, ensure effective work of bearing 9, avoid the generation of catching phenomenon.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
