Description
Technical field
The utility model relates to a kind of long shaft submerged pump.
Background technique
Long shaft submerged pump in the market, under special liquid, the degree of depth reaches 6 meters when above, because pump structure is the two cover corner connection corner-kick bearings that adopt above, intermediate section and hypomere and pump cover place all adopt guide bearing aiding support, there is inferior position easy to wear in guide bearing, thus pump operation get up, steady not, and working life is not long, maintenance difficult.
Model utility content
The technical problems to be solved in the utility model is, the faultiness design that exists for prior art is a kind of make pump operation steadily, the long shaft submerged pump of long service life.
The technical solution of the utility model is, a kind of long shaft submerged pump, it comprises the pump housing, impeller, pump cover, external mounted machine envelope, machine sealed cover, end seal, motor, motor cabinet and base, lower end at motor is provided with coupling, in the lower end of coupling, be provided with axle, upper axle is connected with lower shaft by middle coupling band, on upper axle, be provided with rolling bearing, on the pump housing, be provided with grease chamber, in grease chamber, be provided with oil water probe, end seal and machine sealed cover, on base plate, be provided with upper support pipe, middle bearing bracket, is provided with drain pipe in a side of the pump housing.
The utility model has the advantages that novel structure, operate steadily, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Embodiment
As shown in Figure 1, a kind of long shaft submerged pump, it comprises the pump housing 1, impeller 2, pump cover 3, external mounted machine envelope 4, machine sealed cover 5, end seal 6, motor 12, motor cabinet 14 and base 17, in the lower end of motor 12, be provided with coupling 13, in the lower end of coupling 13, be provided with axle 19, upper axle 19 is connected with lower shaft 22 by middle coupling band 20, on upper axle 19, be provided with rolling bearing 16, on the pump housing 1, be provided with grease chamber 24, in grease chamber 24, be provided with oil water probe 23, end seal 6 and machine sealed cover 5, on base 17, be provided with upper support pipe 10, middle bearing bracket 18, a side at the pump housing 1 is provided with drain pipe 11.
The utility model is loaded onto two cover rolling bearings 16 on upper axle 19, on base 17, load onto respectively motor cabinet 14, upper support pipe 10, middle bearing bracket 18, note between middle bearing bracket 18 and upper support pipe 10 with phenyl tetrafluoride pad sealing (lower same), then by axle 19 and on rolling bearing 16 pack into together in base 17 and middle bearing bracket 18, with bearing gland 15, axial restraint, in middle bearing bracket 18 lower ends, load onto intermediate support pipe 9, coupling band 20 in the middle of being inserted on upper axle 19, then pack successively lower support pipe 8 into, bearing 21, angular contact ball bearing 7, oil water probe 23, in grease chamber 24, pack end seal 6 and machine sealed cover 5 into, in pump cover 3, pack external mounted machine envelope 4 into, in the lower end of pump cover 3, be inserted in impeller 2, the pump housing 1, load onto drain pipe 11, finally load onto coupling 13, motor 12, complete assembling.
As shown in Figure 1, upper axle 19, lower shaft 20 all adopt bearing supporting and supporting outside seal, and axially two have two seals, guarantees so not feed liquor body of bearing, once the effect of oil water probe 23 is to have liquid to enter bearing, oil water probe 23 meeting generation signals, stops motor operation.The utility model structure is novel, operates steadily, and reliability is high, long service life.
