Abstract
The utility model discloses a radial force stabilizing device of a submersible sand discharging pump and relates to the field of submersible pumps of mechanical engineering. The radial force stabilizing device of the submersible sand discharging pump mainly solves the problems that a motor bearing is prone to damage and abrasion of an impeller is fast. The radial force stabilizing device of the submersible sand discharging deice is characterized in that two bearings are arranged at the lower end portion of an extending shaft of a motor rotor, the bearings are fixed in a bearing base shell and are arranged on the same shaft with the motor bearing and the impeller. The bearings are protected by a bearing gland and a sealing gland, and water can be prevented from entering through mechanical sealing and a sealing ring. According to the radial force stabilizing device of the submersible sand discharging pump, through fixation of the end portion of a rotor shaft, radial force generated by rotation of the impeller is stable, the radial stability is obviously improved, and the quality of the submersible sand discharging pump is improved.
Description
Affiliated technical field
The utility model relates to mechanical submersible pump field, relates in particular to the mine sand discharge apparatus that draws water.
Background technique
At present, existing submersible sand discharging pump is to be made of the electromechanical structure water outlet, water conservancy diversion cover, motor loam cake, motor casing, motor lower cover, rotor, upper bearing (metal) shell, upper bearing (metal), lower bearing shell, lower bearing, capsul, impeller, stator, the pump housing, base.Impeller is assemblied in the rotor shaft lower end, and axle head stretches out longer, and impeller progression is more many, and axle head stretches out more long.During running, because the radial force effect, the impeller swing is easy to wear, causes leakage rate big, and simultaneously, bearing bearing radial force load increases, and is fragile, makes product not long working life, causes difficulty for user installation, transportation.
Summary of the invention
(1) purpose that shows
The utility model has overcome shortcoming of the prior art, and a kind of rotor axle head fixing device is provided, and the radial force that produces when making the submersible sand discharging pump work is stable, can solve the problem that motor bearings is fragile, damage in impeller is fast, thereby improves product working life.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of submersible sand discharging pump radial force stabilizer, it comprises: in water outlet (14) bottom motor (13) is installed, at rotor shaft (1) extension, impeller (6), bearing (10), bearing base (3) are linked in sequence, rotor shaft (1) end bearing (10) is fixed in bearing base (3) shell, and is coaxial with motor bearings (12).In rotor shaft (1) end two bearings (10) are installed, bearing (10) is fixed in bearing base (3) shell, and the bottom is fixing by bearing gland (5), seal ring (4) sealing, and M8 bolt (11) is fastening; Top is by mechanical seal (9) sealing, M6 bolt (8) fit sealing gland (2).When motor (13) is worked, impeller (6) rotation, medium is discharged by water outlet (14), and the radial force that impeller (6) rotation produces is in rotor shaft (1) end maximum, and is stable by bearing (10).For guaranteeing bearing (10) proper functioning, the bottom is fixing by bearing gland (5), seal ring (4) sealing, and M8 bolt (11) is fastening.Top is sealed by mechanical seal (9), M6 bolt (8) fit sealing gland (2) guarantees not intake in the mechanical seal (9), and outside framework oil seal (7) is installed above the sealing gland (2), prevent that foreign matter from entering in the mechanical seal (9), guaranteed the normal operation of bearing (10).
(3) beneficial effect
The beneficial effects of the utility model are, this device is submersible sand discharging pump radial force stabilizer, fix by the rotor axle head, the radial force that the impeller rotation produced when submersible sand discharging pump was turned round is stable, and the impeller swing reduces, and acts on the radial load reduction that motor bearings bears, even product turns round for a long time, damage in impeller is also less, and bearing can not damage, and has improved quality of product.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that the utility model product submersible sand discharging pump is always schemed.
Fig. 2 is partial enlarged drawing among Fig. 1, i.e. the sectional structural map of the utility model enforcement.
Among the figure 1, rotor shaft, 2, sealing gland, 3, bearing base, 4, seal ring, 5, bearing gland, 6, impeller, 7, outside framework oil seal, 8, the M6 bolt, 9, mechanical seal, 10, bearing, 11, the M8 bolt, 12, motor bearings, 13, motor, 14, water outlet.
Embodiment
In Fig. 1, submersible sand discharging pump motor (13) places water outlet (14) bottom, and motor bearings (12) is assemblied in motor (13) cartridge housing, and rotor shaft (1) one end of motor (13) is stretched in the outside.
Figure 2 shows that the utility model enforcement structure, in rotor shaft (1) bottom 2 bearings (10) are installed, by bearing (10), connect rotor shaft (1) and be fixed in bearing base (3) shell, when the submersible sand discharging pump work, impeller (6) rotation, the radial force that produces is in rotor shaft (1) end maximum, and by the stable buffering of bearing (10), radial force reduces, impeller (6) swing is reduced, and the radial load that motor bearings (12) bears reduces.For guaranteeing bearing (10) proper functioning, the bottom is by bearing gland (5) protection, and seal ring (4) is installed on bearing gland (5) seal groove, guarantees not intake in bearing (10) chamber M8 bolt (11) connection bearing base (3) and bearing gland (5).Mechanical seal (9) is installed on top, and M6 bolt (8) connection bearing base (3) and sealing gland (2) guarantee not intake in the mechanical seal (9).Outside framework oil seal (7) is installed above the sealing gland (2), is prevented that foreign matter from entering in the mechanical seal (9), guaranteed the normal operation of bearing (10).
Claims (2)
1. submersible sand discharging pump radial force stabilizer, in water outlet (14) bottom motor (13) is installed, at rotor shaft (1) extension, impeller (6), bearing (10), bearing base (3) are linked in sequence, it is characterized in that: rotor shaft (1) end bearing (10) is fixed in bearing base (3) shell, and is coaxial with motor bearings (12).
