Abstract

The utility model discloses a submersible pump base comprising a bottom plate (9) and a fixing plate (8). The upper end face of the bottom plate (9) is provided with a step II (11) upwardly; the step II (11) is provided with a groove; the bottom plate (9) is provided with a plurality of mounting holes outside the step II (11); the center of the fixing plate is provided with a through hole; the fixing plate is fixedly mounted at the step II of the bottom plate. The submersible pump base has the advantages that a mounting shaft can be passed through the through hole in the center of the fixing and be connected with a bearing, the mounting shaft and the fixing plate are mounted together at the step II of the bottom plate, the part, passing the through hole, of the mounting shaft is hermetically arranged between the bottom plate and the fixing plate, a motor shell is arranged outside the base, and full sealing of the bearing is achieved; namely, when a submersible water operates underwater, the bearing and a water source can be isolated, and direct contact between the bearing and the water source is avoided; by the use of the submersible pump base, the problem that dropping of the bottom plate causes flooding of the bearing is avoided; the service life of the whole submersible pump is prolonged accordingly.

Description

Submersible pump base
Technical field
The utility model relates to a kind of base, and specifically a kind of submersible pump base, belongs to submersible pump technical field.
Background technique
Submersible pump is as a kind of water treatment instrument, different from common suction engine, its work that pulls the plug, mainly by base, installation shaft, motor housing, motor and water pump, formed, the bottom of installation shaft is arranged on base by bearing, and motor is arranged in installation shaft, and motor housing is positioned at motor outside, water pump is positioned at the top of motor, and the pump shaft of water pump is connected with the output shaft of motor by coupling; Before turn on pump, suction pipe and pump planted agent are full of liquid, after turn on pump, impeller High Rotation Speed, liquid is wherein along with blade rotates together, under the effect of centrifugal force, fly away from impeller and outwards penetrate, the liquid of ejaculation speed in pump case explosion chamber is slack-off gradually, and pressure increases gradually, then from the discharge tube of pump discharge, flow out, thereby realize draining; Be widely used in people and animals' water in field irrigation and mountain area, plateau, can be for city, factory, railway, mine, building site water supply and sewage.
As shown in Figures 2 and 3, existing submersible pump base is comprised of base body 2 and end cap 7, and the upper-end surface of base body 2 upwards forms two-layer step I5; On base body 2, the outside that is positioned at two-layer step I5 has several mounting holes 3; The center of base body 2 has through hole; During installation, base body 2 can be passed in the lower end of installation shaft 1, and be connected with bearing, then end cap 7 is arranged on to the downside of base body 2, installation shaft can be sealed in the cavity forming between end cap 7 and base body 2 part through through hole; The motor housing that adds upper bed-plate body 2 outsides, has realized the sealing to bearing; When submersible pump is worked under water, bearing and water source can be separated, avoid bearing directly to contact with water source, and then prevent the situation generation that damages bearing because of water inlet.But in actual use, end cap 7 easily comes off, and end cap 7 comes off and can cause bearing water inlet, not only bad for the work of submersible pump, and can damage bearing.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of submersible pump base, bearing and water source not only can be separated, and avoids bearing directly to contact with water source, and can reduce the situation generation of bearing waterlogged damage.
To achieve these goals, the technical solution adopted in the utility model is: a kind of submersible pump base, comprise base plate and fixed plate, and the upper-end surface of described base plate upwards forms one deck step II; On described step II, have groove; On described base plate, the outside of step II has several mounting holes; The center of described fixed plate has through hole, and fixed plate is fixedly mounted on the step II place on base plate.
Preferably, on described fixed plate, the surrounding of through hole has fixed hole, on described step II, have with fixed hole match, attachment hole that quantity is identical.
Preferably, the downside of described base plate is provided with projection.
Compared with prior art, the utility model, by existing base is improved, is set to the structure being comprised of base plate and fixed plate, installation shaft can be passed to the through hole at fixed plate center, and be connected with bearing, then installation shaft is arranged on to the step II place of base plate together with fixed plate; Installation shaft can be sealed between base plate and fixed plate the part through through hole; Add the motor housing of chassis outer side, realized the sealing in all directions of bearing; When submersible pump is worked under water, bearing and water source can be separated, avoid bearing directly to contact with water source, this structure there will not be base plate to come off to cause the situation of bearing water inlet to occur; And then extend working life of whole submersible pump.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of existing base;
Fig. 3 is the use phase diagram of existing base.
In figure: 1, installation shaft, 2, base body, 3, mounting hole, 4, projection, 5, step I, 6, end cap mounting hole, 7, end cap, 8, fixed plate, 9, base plate, 10, fixed hole, 11, step II.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, this submersible pump base comprises base plate 9 and fixed plate 8, and the upper-end surface of described base plate 9 upwards forms one deck step II11; On described step II11, have groove; On described base plate 9, the outside of step II11 has several mounting holes; The center of described fixed plate 8 has through hole, and fixed plate 8 is fixedly mounted on the step II11 place on base plate 9.
During use, one end of installation shaft 1 can be passed to the through hole of fixed plate 8 centers, and be connected with bearing; Then installation shaft 1 is arranged on to the step II11 place of base plate 9 together with fixed plate 8, and base plate 9 is fixedly connected with fixed plate 8; Can make like this installation shaft 1 be sealed in the cavity forming between step II11 and fixed plate 8 through the part of through hole, realize the sealing to bearing; When submersible pump is worked under water, bearing and water source can be separated, avoid bearing directly to contact with water source, and this structure there will not be base plate 9 to come off to cause the situation of bearing water inlet to occur; And then extend working life of whole submersible pump.
Preferably, can be on described fixed plate 8, the surrounding of through hole has fixed hole 10, on described step II11, have and fixed hole 10 matches, quantity is identical attachment hole; By link, fixed plate 8 can be connected with base plate 9, this structure is more convenient is installed on dismounting.As being provided with screw thread in fixed hole 10 and attachment hole, utilize screw bolt passes attachment hole and fixed hole 10 that both are linked together, by realize its installation and removal to different direction swivel bolt, simple to operate.
Preferably, can be provided with at the downside of described base plate 9 projection 4, can avoid the direct kiss the earth of base plate 9, reduce its friction, and then extend the working life of base plate 9.
