Abstract
The utility model is a generic water pump product, and is a shockproof major structure type long shaft drowned pump in particular. An upper metal bearing and a lower metal bearing are provided on a main shaft above an impeller. A main body connecting pipe and a main body shaft protecting tube are provided between the upper metal bearing and the lower metal bearing. A mechanical seal is provided above the upper metal bearing and two mechanical seals are provided under the lower metal bearing. A lower shaft protecting tube and a medium shaft protecting tube are provided around a transmission shaft above the upper metal bearing and close to periphery of a guide bearing. Disposable packing lubrication coolants are provided in the sealed chamber formed between a lower shaft protecting tube, the medium shaft protecting tube and the transmission shaft. The guide bearing of the utility model does not need pre-lubricating before start-up; the utility model is easy to be installed and operated, needs nothing but an ordinary three-phase asynchronous motor. The pump is more widely applied with use and maintenance cycle significantly increased.
Description
Technical field
The utility model is general water pump series products, especially a kind of shockproof agent structure formula borehole shaft drivenpump, it is applicable to electric power dell taking and discharging, Ferrous Metallurgy taking and discharging, petrochemical industry and airport taking and discharging, municipal dell taking and discharging, deep-well water intaking, and other all can select the occasion of borehole shaft drivenpump for use.
Background technique
Traditional borehole shaft drivenpump comprises compositions such as intake pipe, impeller, blower inlet casing, pump shaft, transmission shaft, guide bearing, connecting tube, this pump in the running, the axial force that impeller produces, be delivered to power section more than the mounting base by transmission shaft, radial force is then undertaken by the guide bearing below the mounting base, so the problem that produces is: (1) is higher to component processing, requirements on transport, and on-the-spot installation must be undertaken and debugging by the professional workforce.(2) owing to have the gap between guide bearing and the rotating shaft, rotatable parts can be produced in the running radially wobble, so just produced vibrations.(3) this pump must carry out fully pre-profit to guide bearing before startup, uses programmed sequence of operations loaded down with trivial details.(4) because the guide bearing of bearing radial force weares and teares easily, cause the grazing of impeller and blower inlet casing and damage equipment, so will often change, maintenance period is shorter.
Summary of the invention
Technical problem to be solved in the utility model: be to provide a kind of and can prevent to shake, simple to operate, shockproof agent structure formula borehole shaft drivenpump that Applicable scope is wider.
For solving above technical problem, the technological scheme that is adopted is such: at impeller and main shaft part that is shank, the main shaft that will be positioned at the impeller top partly is provided with metal bearing and following metal bearing, main body connecting tube and main body are housed between the metal bearing up and down protect central siphon, establish one mechanical seal above last metal bearing, twice mechanical seal is established in the below of following metal bearing.In addition, around the transmission shaft of last metal bearing top, and near the periphery of guide bearing, be provided with down and protect central siphon and central siphon is protected in the centre.Protect central siphon down, the centre is protected in the closed sandwich cavity that forms between central siphon and the transmission shaft, and disposable packing lubrication freezing mixture is set.
Because adopt above technological scheme, the effect of generation is conspicuous:
1, the part processing and the assembly precision of shank only depended in the technology gap between impeller and the blower inlet casing, and this gap is supported for metal bearing and is easy to guarantee.And the metal bearing play is very little, can not produce swing during wheel rotation, so can be shockproof.
2, because all bearings do not contact with sending medium, so the Applicable scope of pump is wider, use and service cycle prolong greatly.
3, guide bearing has prolonged the wear-out period of guide bearing because of bearing radial force not, even worn and torn, also can not have influence on the gap between impeller and the blower inlet casing.
4, need not before each the startup, guide bearing to be moistened in advance.
5, installation and simple to operate.
Description of drawings

Fig. 2 is the partial enlarged drawing of shanks such as the lower end impeller, main shaft of pump among Fig. 1.
Among the figure: 1, intake pipe 2, impeller 3, mechanical seal 4, blower inlet casing 5, mechanical seal 6, step 7, metal bearing 8, main body connecting tube 9, main shaft 10, main body are protected central siphon 11, upper bearing bracket 12, are gone up metal bearing 13, mechanical seal 14, protect central siphon 15, guide bearing body 16, intermediate connection tube 17, transmission shaft 18, guide bearing 19, centre down and protect central siphon 20, intermediate shaft coupling 21, base 22, motor cabinet 23, coupling 24, motor down
Embodiment
With reference to Fig. 1, Fig. 2, the utility model comprises intake pipe (1), impeller (2), water conservancy diversion (2), blower inlet casing (4), main shaft (9), transmission shaft (17), guide bearing (18), intermediate connection tube (16) and base (21) from bottom to up, at the main shaft (9) that is positioned at impeller (2) top partly, metal bearing (12) and following metal bearing (7) are set, and installation main body connecting tube (8) and main body are protected central siphon (10) between the metal bearing up and down.For the external agency of resistance enters in the cavity between the upper and lower bearing, specially mechanical seal (13) is set in the top of last metal bearing (12), in the below of descending metal bearing (7) twice mechanical seal (5), (3) are set.At the transmission shaft (17) of last metal bearing (12) top on every side and near the periphery of guide bearing (18), be provided with down and protect central siphon (14) and central siphon (19) is protected in the centre, and protect central siphon down, the centre is protected in the Sealed sandwich cavity that forms between central siphon and the transmission shaft, and disposable packing lubrication freezing mixture is set.
As Fig. 2, from the mechanical seal (13) of the intake pipe (1) of main shaft lower end, be the complete independence of the present utility model and the body type structure of having a style of one's own until the main shaft upper end, impeller and blower inlet casing gap have promptly been assembled by part before dispatching from the factory and have been realized.
As Fig. 1, transmitting torque is only played in the middle driving section of main shaft (9) top, so when using the utility model, as long as shank and driving section are made up, thereby power engine need not to use special-purpose well pump motor, only adopted common threephase asynchronous just.
