Description

A kind of horizontal self-sucking pump
Technical fieldThe present invention relates to a kind of pump, relate in particular to a kind of self-priming pump.
Background techniqueSelf-priming centrifugal pump is to use more pump class in the industrial production, traditional self-priming centrifugal pump is need not pour water before startup (back startup for the first time is installed still need pour water), through short-time running, by the effect of pump itself, namely can finish self-priming, drop into proper functioning.But still there is shortcoming in traditional self-priming centrifugal pump in the process that reality is used, for example: 1, it adopts double shrouded wheel, can only adapt to no particle, pure medium operating mode, and this just brings significant limitation to use; 2, self-priming time 10s at least, self-priming time is long; 3, suction capacity is low, and the self-priming height can only reach 5-7m; 4, it can only normally use in-20 ℃~+ 120 ℃, and can only bear the pressure of 1Mpa, brings narrow limitation to use; 5, performance is low, and maximum flow can only reach 600m3/h, and lift can only be reached for 80m; So, for solving the inconvenience that traditional self-priming centrifugal pump brings to industrial production, the producer also adopts performance and efficient to be better than the self-priming pump of traditional self-priming centrifugal pump, and these non-traditional self-priming centrifugal pumps are made of jointly preposition self-priming apparatus and centrifugal pump, preposition self-priming apparatus mainly is that the employing pot type is taken out self-priming or blower fan is taken out self-priming or vacuumized to reach the self-priming purpose with diaphragm pump, but these contain non-traditional self-priming centrifugal pump and all exist floor space bigger, waste material, the drawback that cost is high, self-priming pump with the pot type self-priming apparatus is example, when feed flow during greater than 500m3/h, the volume of knockout drum can reach 3m3, this is waste material not only, and has very large floor space.
Summary of the inventionThe object of the present invention is to provide and a kind ofly not only can realize direct self-priming, and suction capacity is strong, the time short, be fit to contain the operating mode of granule medium, save material, floor space is little, the horizontal self-sucking pump that cost is low.
The present invention establishes self-priming impeller and black box etc. between the pump housing and link press span, concrete technological scheme of the present invention is as follows:
The present invention mainly includes the pump housing, underframe, impeller, pump shaft, link press span, bearing bracket stand, pump cover, seal case, self-priming impeller and mechanical seal, the pump housing lower end that wherein is provided with fluid inlet and outlet connects the underframe that is used for support by bolt, best, establish the center inlet hole wearing plate corresponding with pump housing import in the inside of the described pump housing, to increase the wear resistance of overcurrent part; The inside of the described pump housing is provided with impeller, this impeller is preferably half-opened impeller, it is fixed on the front end of horizontal pump shaft by impeller nut, described pump shaft passes link press span, the bearing bracket stand that is positioned at pump housing rear portion successively, the rear end is positioned at outside the bearing bracket stand housing, and wherein the front end of link press span links to each other with the rear end of the pump housing by bolt; The rear end of link press span links to each other with bearing bracket stand by bolt, the front portion is provided with front roll bearing in the described bearing bracket stand housing, rear rolling bearing is established at the rear portion in the bearing bracket stand housing, described front roll bearing and rear rolling bearing all are located between pump shaft and the bearing bracket stand, and rear rolling bearing is fixed by the bearing gland that links to each other with bearing bracket stand; The lower end of described bearing bracket stand also connects the underframe that is used for support by bolt; The rear portion of above-mentioned impeller is provided with the pump cover that is enclosed within on the pump shaft, and this pump cover is provided with the ring of evagination, and this ring is located between the described pump housing and the link press span, and pump cover is located; Be provided with the seal case that is enclosed within on the pump shaft in the formed die cavity of described pump cover and link press span, also be provided with the ring of evagination on the sealing casing, this ring is located between described pump cover and the link press span, and black box is located; One bolt is arranged, and it links to each other with link press span, seal case and pump cover successively, follows pump shaft and rotates to prevent them; Be provided with the self-priming impeller in the die cavity of above-mentioned seal case inside, this self-priming impeller is made up of axle sleeve and blade, the axle sleeve of self-priming impeller links to each other with pump shaft by key, the axle sleeve front portion is provided with 4 uniform axial air-breathing through holes, air-breathing through hole is made up of two sections different holes of internal diameter, front and back, its leading portion air inlet internal diameter is greater than the back segment internal diameter of giving vent to anger, and the outside of described axle sleeve is provided with 10 uniform blades, is provided with between the axle sleeve part at blade rear portion and the seal case and is enclosed within mechanical seal on the pump shaft; Above-mentioned black box is provided with the relief opening that communicates with its inner die cavity, the air of medium internal mix when discharging self-priming.
When starting, the present invention opens machine envelope sparge water, need not in pump, to pour water, directly replace the process of pouring water with sparge water, the self-priming impeller rotates at a high speed and makes into the interruption-forming vacuum after starting, and the air in the suction line passes through the pump housing, self-priming impeller front portion is the zone of high pressure, the rear portion is low pressure area, and air sucks the back and flows to low pressure area by the zone of high pressure, and is expelled to gas exhaust piping through the further pressurization of self-priming impeller, gas exhaust piping is connected to the pipeline that spues, so a large amount of air is expelled to the pipeline that spues; On the other hand, the gas-liquid mixture that is sucked by impeller is discharged in the pipeline that spues the part current and gets back to impeller outer edge through pump housing road, the gas of wherein separating continues to guarantee the isolation of gas between inlet ductwork and the export pipeline among pump discharge is discharged into the downstream pipeline medium retention pump housing, guarantee the continuous operation of self-priming impeller, air emptying in suction line, pump enters normal operating phase, if pump sucks air during normal the operation, by the self-priming impeller air is discharged to the downstream pipeline, thereby the appearance that can not cause pumping hole ring or mechanical seal dry grinding has guaranteed the safe operation of pump, reduces because the production accident that the suction line problem causes.
The present invention compared with prior art has following advantage:
1. need not storaging liquid in the pipe, just directly start and moment to reach the self-priming effect, shortened self-priming time greatly, save the energy, and avoided the corrosion phenomenon that produces because of the long term storage medium.
