Description

Technical Field

[0002] Submersible electric pumps for sewage and sludge are widely used in various sewage discharge occasions. They are a commonly used pump product. Their main features are that the motor and pump are compact as one, the overall structure is compact, the volume is small, and there is no need to build a pump room. The whole machine can work by being submerged in water, which can greatly reduce engineering construction. Mechanical seal refers to a device that prevents fluid leakage by maintaining contact and relative sliding of at least one pair of end faces perpendicular to the axis of rotation under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the cooperation of the auxiliary seal. The elastic loading mechanism and the auxiliary seal are mechanical seals of metal bellows, which we call metal bellows seals. In light seals, rubber bellows are also used as auxiliary seals. The elastic force of rubber bellows is limited, and generally a spring is required to satisfy the loading elastic force. "Mechanical seals" are usually referred to as "machine seals".

The inside of the slide groove 19 is slidably connected to the outside of the slide block 12.

[0025] In this embodiment, the adjustment component includes a No. 2 motor 13 fixedly mounted on the inner wall at the back of the box body 2, the output shaft of the No. 2 motor 13 is fixedly connected to a rotating shaft 14, the outer side of the rotating shaft 14 is fixedly connected to a gear 15, the right inner wall of the box body 2 is slidably connected to a tooth plate 16 meshing with the gear 15, the right side of the tooth plate 16 is fixedly connected to a movable block 17, the interior of the movable groove 20 is slidably connected to the outer side of the movable block 17, and the top of the tooth plate 16 is fixedly connected to the bottom of the cabin body 3.

[0026] The working principle of the above embodiment is:

[0027] When the submersible sewage electric pump shaft seal positioning tool is used, a suitable limit plate 8 is selected according to the size of the seal, and the two limit rods 11 are manually pushed apart to make the two limit rods 11 move away from each other, and the limit rod 11 stretches the spring 10. By setting a slider 12 and a slide groove 19, the limit rod 11 is limited and supported to increase the stability of the limit rod 11 during movement. Then, the connecting groove on the limit plate 8 is inserted into the outer side of the connecting rod 7, and then the two limit rods 11 are loosened, and the two limit rods 11 are relatively moved by the spring 10 reset and inserted into the limit groove provided on the limit plate 8, so that the limit plate 8 is limited and fixed, and then the seal is placed between the two limit plates 8, and the No. 1 motor 4 is started, and the output shaft of the No. 1 motor 4 drives the reverse screw 5 to rotate, and the reverse screw 5 drives the threaded block 6 to rotate, and the support rod 18 is set. The threaded block 6 is limited and supported so that the threaded block 6 can only move left and right, thereby driving the two threaded blocks 6 to move relative to each other, and then driving the two limit plates 8 to move relative to each other to clamp and fix the machine seal. By setting the anti-slip pad 21, the stability of the limit plates 8 when clamped and fixed is increased. By setting the adjustment component, the No. 2 motor 13 is started, and the output shaft of the No. 2 motor 13 drives the rotating shaft 14 to rotate, the rotating shaft 14 drives the gear 15 to rotate, and the gear 15 drives the tooth plate 16 to move up and down. By setting the movable block 17 and the movable groove 20, the tooth plate 16 is limited and supported, and the stability of the tooth plate 16 when moving is increased. The tooth plate 16 drives the box body 2 to move up and down, so as to achieve the effect of adjusting the height of the machine seal, thereby facilitating the user to detect the machine seal, and then facilitating the use of users of different heights, facilitating the use of users, and improving the practicality of the positioning tooling.
