The utility model discloses the structure of cancellation pump at the edge of export flange dish with the boss and bore the screw thread hole changes into and adds the boss and bore the screw thread hole on export flange neck, and processing is more convenient, and the structure is simpler, compact, has both saved the material, has also reduced the possibility that causes the interference to other part dismouting of pump.
Description
Technical Field
The utility model relates to a condensate pump, in particular to condensate pump flushing line structure.
Background
Generally, because the temperature of a medium conveyed by a condensate pump is high, a mechanical seal flushing system needs to be configured to flush and cool a mechanical seal when the condensate pump runs, and air and steam in a sealing cavity are discharged at the same time, so that dry grinding overheating damage of the mechanical seal is prevented. At present, referring to fig. 1, the structure of the mechanical seal flushing pipeline 3 of the condensate pump is generally as follows: a semicircular boss 102 is arranged on the outer wall of an outlet flange plate 101 of the pump body 1, a threaded hole 103 is processed on the boss 102 to serve as a boss interface, a long through hole 104 is drilled to the inner wall of the outlet flange plate 101, and a flushing pipeline 3 is led out from a mechanical seal cover 2 and then connected to the boss 102. When the condensate pump operates, high-pressure water at the outlet flange plate 101 returns to the pump cavity after washing the sealed cavity through the washing pipeline 3.
The disadvantages of this flushing line 3 construction are: for a boss interface, the operation of processing threads on the edge of an outlet flange plate 101 of a pump body 1 is inconvenient, and a long through hole 104 is easy to drill off; secondly, the axial distance between the boss 102 on the outlet flange plate 101 and the center of the interface on the mechanical seal gland 2 is small, the flushing pipeline 3 needs to turn and turn back twice to normally butt the boss 102 and the mechanical seal gland 2, so that not only is the material wasted, but also the processing difficulty is increased, and meanwhile, the space occupied by the flushing pipeline 3 is large, and the operation of other parts is interfered; third, the bosses 102 on the outlet flange 101 may interfere with the flange connection bolts, which may affect the normal installation of the flange.
SUMMERY OF THE UTILITY MODEL
The utility model provides a to above-mentioned problem, a condensate pump flushing line structure is provided.
The purpose of the utility model can be realized by the following technical scheme: a condensate pump flushing pipeline structure comprises a pump body, a mechanical seal gland and a flushing pipeline; the outlet flange of the pump body is provided with a boss on the outer wall of the flange neck, the boss is arranged on the side, close to the mechanical seal, of the outer wall of the flange neck of the outlet flange, a first threaded hole is formed in the boss, the hole bottom of the first threaded hole is provided with a first through hole communicated with the inner wall of the flange neck of the outlet flange, the upper side of the outer wall of the mechanical seal gland is provided with a second threaded hole, the hole bottom of the second threaded hole is provided with a second through hole communicated with the inner wall of the mechanical seal gland, and the two ends of the flushing pipeline are connected with the first threaded hole and the second threaded hole through.
Compared with the prior art, the beneficial effects of the utility model are that: the structure that the pump adds the boss and bores the screw hole at the edge of export flange dish is cancelled, changes to add the boss and bores the screw hole on export flange neck, and processing is more convenient. The flushing pipeline penetrates through a bracket gap of the condensate pump and is turned and folded once to realize the connection of the boss and the mechanical seal gland, the structure is simpler and more compact, materials are saved, and the possibility of interference on the disassembly and assembly of other parts of the pump is reduced.

Detailed Description
The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings to make it clear to those skilled in the art how to practice the invention. While the invention has been described in connection with its preferred embodiments, these embodiments are intended to be illustrative, and not to limit the scope of the invention.
Referring to fig. 2, a condensate pump flushing pipeline structure comprises a pump body 1, a mechanical seal cover 2 and a flushing pipeline 3.
The side, close to the mechanical seal, of the outer wall of the outlet flange neck 101 of the pump body 1 is provided with a boss 102, the boss 102 is provided with a first threaded hole 103, and the bottom of the first threaded hole 103 is provided with a first through hole 104 communicated with the inner wall of the outlet flange neck 101 of the pump body 1.
The machine seals the outer wall upside of gland 2 and is equipped with second screw hole 201, the hole bottom of second screw hole 201 is equipped with the second through-hole 202 with machine seals the inner wall intercommunication of gland 2.
The two ends of the flushing pipeline 3 are respectively connected with the first threaded hole 103 and the second threaded hole 201 through joints.
When the condensate pump operates, high-pressure water at the outlet flange neck 101 of the pump body 1 returns to the pump cavity after flushing the sealed cavity through the flushing pipeline 3.
The scheme changes the structure that the boss 102 is added at the edge of the outlet flange plate of the pump and the threaded hole is drilled into the structure that the boss 102 is added on the outlet flange neck 101 and the threaded hole is drilled, so that the processing is more convenient. Moreover, as can be seen from fig. 2, the flushing pipeline 3 passes through the gap of the bracket 4 of the condensate pump, and is turned and folded once to realize the connection of the boss 102 and the mechanical seal cover 2, so that the structure is simpler and more compact, the material is saved, and the possibility of interference on the disassembly and assembly of other parts of the pump is reduced.
It should be noted that many variations and modifications of the embodiments of the present invention are possible, which are fully described, and are not limited to the specific examples of the above embodiments. The above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. In conclusion, the scope of the present invention should include those changes or substitutions and modifications which are obvious to those of ordinary skill in the art.
