Description

Technical Field

[0001] The utility model relates to the technical field of shielded pumps, in particular to a shielded pump. Background Art

[0002] The drive of ordinary centrifugal pumps is to connect the impeller shaft of the pump with the electric shaft through a coupling, so that the impeller rotates with the motor to work. The canned pump is a sealless pump. The pump and the drive motor are sealed in a pressure vessel filled with pumping medium. This pressure vessel has only static seals, and a wire group is used to provide a rotating magnetic field and drive the rotor. This structure eliminates the rotating shaft sealing device of traditional centrifugal pumps, so it can be completely leak-free.

[0003] The existing shielded pump has no protective structure and is easily damaged by impact during operation, thereby suspending operation and affecting work efficiency. The existing shielded pump cannot adjust the height and cannot be installed in special environments. It needs to be supported by other objects, which is very troublesome. Utility Model Content

[0024] See also Figure 4 The limiting structure includes: four limiting guide rods 15, four guide sleeves 16, four limiting pads 17 and four return springs 18; the four limiting guide rods 15 are respectively installed in the four guide grooves 5, the four guide sleeves 16 are respectively sleeved on the outer wall surfaces of the four limiting guide rods 15, the four limiting pads 17 are respectively installed on the front wall surfaces of the four guide sleeves 16, and the four return springs 18 are respectively sleeved on the outer wall surfaces of the four limiting guide rods 15.

[0025] See also Figure 3 Four anti-skid pads 19 are installed on the lower wall of the fixing seat 2. When in use, the four anti-skid pads 19 can increase the friction with the ground and increase the stability of the shielded pump body 1 when working.

[0026] See also Figure 2 The two protective covers 9 are made of materials that can be magnetically adsorbed. When in use, the operator pulls out the two protective covers 9 along the two first receiving grooves 4. When the inner end faces of the two protective covers 9 contact the two protective guide rods 6 respectively, they are rotated ninety degrees around the two protective guide rods 6 toward the shielded pump body 1. At this time, the two protective covers 9 are respectively adsorbed by the two magnetic suction sheets 8.

[0027] See also Figure 4 Auxiliary wrenches 20 are respectively installed on the lower walls of the four limit plates 7. When in use, the operator presses the auxiliary wrench 20 and drives the guide sleeve 16 to move along the limit guide rod 15 through the limit pad 17. At this time, the reset spring 18 contracts, and the corresponding threaded rod 11 is not restricted and rotates outward around the corresponding load-bearing shaft 10.

[0028] Embodiment 1. In this embodiment, the operator pulls out two protective covers 9 along the two first receiving grooves 4. When the inner end faces of the two protective covers 9 contact the two protective guide rods 6 respectively, they are rotated ninety degrees around the two protective guide rods 6 toward the shielded pump body 1. At this time, the two protective covers 9 are respectively adsorbed by the two magnetic suction sheets 8.

[0029] Specifically, during installation, the operator pulls out two protective covers 9 along the two first receiving grooves 4. When the inner end faces of the two protective covers 9 respectively contact the two protective guide rods 6, they are rotated ninety degrees around the two protective guide rods 6 toward the shielded pump body 1. At this time, the two protective covers 9 are respectively adsorbed by the two magnetic sheets 8.

[0030] Embodiment 2. In this embodiment, the threaded sleeve 14 is rotated around the threaded rod 11 so that the threaded sleeve 14 moves upward along the threaded rod 11. When the threaded sleeve 14 contacts the lower wall surface of the fixed seat 2, the corresponding threaded rod 11 is limited by the threaded sleeve 14 and cannot rotate around the load-bearing shaft 10.

[0031] Specifically, when the installation environment of the shielded pump body 1 requires the shielded pump body 1 to be lifted off the ground, the operator presses the auxiliary wrench 20 and drives the guide sleeve 16 to move along the limiting guide rod 15 through the limiting pad 17. At this time, the reset spring 18 contracts, and the corresponding threaded rod 11 is not restricted and rotates outward around the corresponding load-bearing shaft 10. Then the operator releases the hand that moved the auxiliary wrench 20, and the corresponding reset spring 18 resets, and drives the limiting pad 17 to reset through the guide sleeve 16. At this time, the threaded rod 11 cannot be retracted into the guide groove 5 around the load-bearing shaft 10. At this time, the operator takes out the nearby threaded sleeve 14 along the corresponding second receiving groove 12, and the threaded sleeve 14 disengages from the magnetic suction block 13, rotates the threaded sleeve 14 around the threaded rod 11, and moves the threaded sleeve 14 upward along the threaded rod 11. When the threaded sleeve 14 contacts the lower wall of the fixing seat 2, the corresponding threaded rod 11 is limited by the threaded sleeve 14 and cannot rotate around the load-bearing shaft 10.
