Abstract
The utility model relates to a submerged pump with a long axle, which is mainly composed of a pump body (4), a pump cover (1), an impeller (3), an impeller nut (2), a lower axle (5), an upper axle (11), a coupler (17) and a motor (18). Owing to the adoption of two or more sections of long axles, a coupling axle sleeve (8) is used for ensuring the concentricity of the pump axles through screwed connection, and a sliding bearing (9) is used for enhancing the acid-proof and alkali-proof performances, the service life of the submerged pump with a long axle is increased.
Description
The utility model relates to a kind of Under Water Pumps.
At present, Under Water Pumps is widely used in fields such as electric power, metallurgy, petrochemical industry, environmental protection, pharmacy, is used to carry have certain corrosive liquid body medium.Relevant by retrieval documents and materials, the submerged depth of Under Water Pumps are generally about 3 meters, if just can't normally move when surpassing this limit.The general turn up 2900rpm of homemade Under Water Pumps just can reach designed lift, because rotating speed height, add that the pump shaft coaxality is difficult to guarantee, pump housing high vibration when just having caused the Under Water Pumps operation, noise increases, main shaft fatiguability fracture, defective such as working life is short can not satisfy the needs of some engineerings.
The purpose of the utility model design provides the long shaft submerged pump that a kind of rotating speed is low, dive is dark.
For reaching the purpose of design, long shaft submerged pump adopts common electric machine, and its rotating speed is 1450rpm, but the decline rotating speed of motor can influence the power output of pump.We have done improvement on the overall structure of pump, increased the diameter of impeller and pump case, can guarantee that like this output power of entire pump is constant.When low-speed running, the wearing and tearing of its moving element become very little, and the stability of pump has obtained increase.For reaching the purpose of deep diving, in design, can form pump shaft by two sections or multistage according to the difference of the degree of depth under the liquid, it is characterized in that axle 11 and lower shaft 5 usefulness coupling bands 8 are with scyewed joint.On last axle 11 and lower shaft 5, be respectively equipped with sliding bearing 9 because pump shaft is long, the stability during with the running of assurance pump shaft.
Fig. 1 is the structural representation of long shaft submerged pump.
Structural representation according to Fig. 1 describes its working state in detail below.
Long shaft submerged pump is made up of pump cover 1, impeller nut 2, impeller 3, the pump housing 4, lower shaft 5, last axle 11, drain pipe 6, cooling tube 7, connecting tube 12, base plate 13, bearing support 14, bearing 15, motor cabinet 16, coupling 17 and motor 18.Liquid is discharged by the B end from drain pipe 6 through the centrifugal action of impeller 3 in suction inlet A suction pump.Whole pump shaft is made up of last axle 11 and lower shaft 5, and last axle 11 and lower shaft 5 are with scyewed joint with coupling band 8.The axle sleeve two ends are coaxial each other positioning spigots, upper and lower main shaft and axle sleeve are by the seam location with after being threaded, by positioning screwn that axle and axle sleeve is fastening again, thereby guaranteed the coaxality of whole major axis, sliding bearing 9 is fixed on the intermediate bearing support 10, has designed spiral irregular bosh at the inwall of sliding bearing 9, has set up outer cooling system, cooling liquid flows into the sliding bearing bosh from cooling liquid mouth 19 through cooling tube 7, makes sliding bearing 9 fully be cooled off.Sliding bearing 9 is to select for use the furfuryl alcohol resin impregnated graphite to make, lubricity is good, intensity and resistance to acids and bases than common graphite, polytetrafluoroethylmaterial material are high tens times, and it is not yielding, improve the working life of sliding bearing greatly, thereby long shaft submerged pump can be widely used in all trades and professions.
Claims (4)
1, a kind of long shaft submerged pump, it comprises pump cover (1), impeller nut (2), impeller (3), the pump housing (4), lower shaft (5), last axle (11), a coupling (17), motor (18) are formed, and it is characterized in that: axle (11) and lower shaft (5) are with scyewed joint with coupling band (8) on the described long shaft submerged pump.
2, long shaft submerged pump according to claim 1 is characterized in that axle (is respectively equipped with sliding bearing (9) on (11) and the lower shaft (5).
3, long shaft submerged pump according to claim 2 is characterized in that described sliding bearing (9) is made with the furfuryl alcohol resin impregnated graphite.
4, long shaft submerged pump according to claim 2 is characterized in that sliding bearing (9) is provided with cooling liquid mouth (19).
