Background technique
General water pump except that submersible pump, Under Water Pumps, is essentially horizontal type structure, the pump housing and motor transverse row cloth are provided with, and on the one hand, volume is big, be difficult for fixing, on the other hand, solve the air inlet of pump and the sealing problem that leaks, poor sealing performance with methods such as packing seal, the sealings of deadweight ring, the phenomenon that leaks outside is in various degree in use all arranged, particularly, just more difficult at the leaking outside of the liquid that is corrosive, and the maintenance, repair trouble.
The model utility content
The purpose of this utility model is to provide a kind of improved vertical self-sucking pump, and volume is little, and cost is low, and is fixing easily, and good seal performance, and maintenance, repair are easy.
Vertical self-sucking pump described in the utility model, the pump housing and motor are arranged, divide in the pump housing and be separated with admission chamber and go out sap cavity, admission chamber and the through hole that goes out between the sap cavity are provided with centrifugal impeller, liquid entering hole on the pump housing and liquid outlet are communicated with the admission chamber in the pump housing respectively and go out sap cavity, impeller shaft is connected with motor shaft, its pump housing and motor are vertically arranged the formation vertical structure are set, motor places the top of the pump housing, connecting cover is established at the top of the pump housing, closed chamber is established in the inboard of connecting cover, and the sealing unshrouded impeller that is installed on the impeller shaft is arranged in the closed chamber.
The utility model has been realized the vertical structure mode, and not only volume is little, fixing easily, and can utilize unshrouded impeller to realize mechanical seal, good seal performance, two of the best arranged in co-axial alignment of unshrouded impeller, enhanced leaktightness effect.Simultaneously, the design of connecting cover has made things convenient for maintenance, repair.
Establish the liquid fairlead in the outside of connecting cover, guarantee to have in termination of pumping the backwater of minute quantity to be discharged to the pond from this hole along pipeline, make the ground of the pump housing remain cleaning on every side, any leaks outside does not have yet.
Centrifugal impeller has multiple, as the centrifugal impeller of enclosed, open type, semi-open type and the centrifugal impeller etc. that has the device that minces, and the centrifugal impeller that has the device that minces that preferred properties is good, the device that minces can avoid foreign material to stop up at any time with the foreign material fragmentation.
Impeller shaft is arranged at out in the sap cavity, compact structure, solid and reliable.
In the utility model:
The pump housing and internal structure can adopt made such as magnesium iron, all steel, all steel, fluoroplastic, engineering plastics according to the purposes needs.
The utility model is compared with existing common horizontal self-sucking pump, has following beneficial effect:
(1) vertical structure, volume is little, and cost is low, and is fixing easily, can reduce constant expense in large quantities for the user.
(2) adopt the sealing of two-shipper tool air chamber, unshrouded impeller is realized sealing with impeller shaft rotation acting simultaneously under mutual effect, good seal performance, and also vibration force is little, has reduced the noise of pump.
(3) connecting cover structure, made things convenient for maintenance, repair, as long as connecting cover takes apart, the parts in just can disposable proposition pump housing inner chamber, change impeller, pump shaft is all very light, convenient, maintenance sealing or change the impeller time and can shorten to 30-120 minute by normal 1-2 days.
(4) suction is big, when first the use pump chamber liquid is filled it up with, and under the drive of impeller, makes another pump chamber produce pull of vacuum behind the turn on pump, and liquid moment from 4-5 rice pond will be mentioned in the pump, send after the acting.Through the Preliminary detection test, suction degree of vacuum is 680-720mpa behind the normal turn on pump, no net positive suction head in the pump chamber, the working life of having guaranteed the impeller and the pump housing.
(5) suction capacity is strong, inhales journey after only needing add a diversion toward the pump chamber the inside and can reach 4-5 rice, and reach in work from now on stopping and promptly open promptly with opening, and does not fall at pipeline under the situation of water to reach 9 meters of suction journeys.
The utility model is compared with existing Under Water Pumps, has following beneficial effect:
(1) convenient by dress: can aspirate with flexible pipe with any periphery that is intended to the pond groove by dress, flexible.
(2) reduce fixed cost: compare with the Under Water Pumps of same model, can reduce purchase cost 50%, reduce maintenance cost 50%.
The utility model is mainly the suction that enterprise solves fluids such as clear water, dope, mud, solvent or diluent, slag liquid, the task of falling pond, feeding, is mainly used in enterprises such as environmental protection, generating, chemical industry, mining, ore dressing, papermaking, cement, printing and dyeing, medicine, food.
