Description

Technical Field

[0001] The utility model relates to the technical field of submersible slurry pumps, in particular to a submersible slurry pump with a visible glass cover device. Background Art

[0002] The development of submersible slurry pump is to adapt to the increasingly complex working conditions and facilitate users. It has a more flexible way of use and fills a part of the blank in the application of slurry pump. When the liquid depth is deep and there is no good slurry outlet, that is, when the traditional slurry pump cannot be installed and operated, the submersible slurry pump can fill this part of the blank working point. The submersible slurry pump is a motor and pump coaxially submerged in water to work;

[0003] However, since the submersible slurry pump transports a large amount of particles, sand, and mud, and works underwater, long-term operation will lead to the inability to observe the wear of the shaft sealing components (packing, stuffing box, shaft sleeve, packing ring) and inconvenience in subsequent maintenance. Later maintenance of the shaft sealing components also requires the submersible slurry pump to be lifted out of the water for repair, which greatly increases the difficulty and cost. Based on this, a submersible slurry pump with a visual glass cover device is proposed. Utility Model Content

[0028] The mounting mechanism 6 includes a mounting shell 61, which is fixedly mounted on the connecting frame 2. A fixing rod 63 is fixedly mounted on the visual glass cover 4. The first inclined block 64 is fixed by the fixing rod 63, and the first inclined block 64 is driven to move by the fixing rod 63. The first inclined block 64 is fixedly mounted on the end of the fixing rod 63 away from the visual glass cover 4. A second inclined block 65 is movably mounted on the inner top wall of the mounting shell 61. When the inclined surface of the first inclined block 64 and the inclined surface of the second inclined block 65 contact each other, the second inclined block 65 is driven to move upward as the first inclined block 64 moves, and the inclined surface of the second inclined block 65 fits the inclined surface of the first inclined block 64. A first rectangular groove 65 is provided on the mounting shell 61. 2. The setting of the first rectangular groove 62 facilitates the first inclined block 64 to enter the mounting shell 61, which is beneficial to the use of the first inclined block 64. The first rectangular groove 62 is adapted to the first inclined block 64. A telescopic rod 66 is fixedly installed between the top of the second inclined block 65 and the inner top wall of the mounting shell 61. The second inclined block 65 is limited by the setting of the telescopic rod 66. The telescopic rod 66 is formed by a thick rod and a thin rod. A spring 67 is arranged on the outer sleeve of the telescopic rod 66. The setting of the spring 67 drives the second inclined block 65 to reset when the spring 67 resets. One end of the spring 67 is fixedly installed on the inner top wall of the mounting shell 61, and the other end is fixedly installed on the top of the second inclined block 65.

[0029] Embodiment 2

[0030] Based on Example 1, please refer to Figure 1-Figure 5 As shown, a threaded rod 69 is fixedly installed on the second inclined block 65, and a second rectangular groove 68 is opened on the mounting shell 61. The second rectangular groove 68 provides a moving space for the threaded rod 69, and the threaded rod 69 passes through the second rectangular groove 68. A threaded fixing ring 610 is sleeved on the second rectangular groove 68.

When the shaft sealing component 3 needs to be maintained, it is only necessary to rotate the threaded fixing ring 610 to disengage it from the outer surface of the mounting shell 61, thereby releasing the position fixation of the threaded rod 69, and then pull the second inclined block 65 upward through the threaded rod 69 until the second inclined block 65 moves to a certain position, and then the first inclined block 64 is driven to disengage from the mounting shell 61 through the visual glass cover 4, so as to complete the disassembly of the visual glass cover 4, which is beneficial to the maintenance of the shaft sealing component 3. When the maintenance of the shaft sealing component 3 is completed, the first inclined block 64 is inserted into the mounting shell 61 through the first rectangular groove 62. When the first inclined block 64 is When the inclined surface of the block 64 contacts the inclined surface of the second inclined block 65, the movement of the first inclined block 64 drives the second inclined block 65 to move upward, and at the same time drives the telescopic rod 66 and the spring 67 to be compressed, until the first inclined block 64 moves to a certain position, the telescopic rod 66 and the spring 67 perform a reset movement and then drive the second inclined block 65 to move downward, and the position of the first inclined block 64 is fixed by the second inclined block 65, thereby completing the installation of the visible glass cover 4, and then rotating the threaded fixing ring 610 so that the threaded fixing ring 610 contacts the outer surface of the mounting shell 61, thereby realizing the position fixing of the second inclined block 65, which is conducive to fixing the position of the second inclined block 65, thereby ensuring the position fixing of the visible glass cover 4.
