Description
Technical Field
The utility model belongs to the technical field of the industrial pump, specifically relate to an integral type pump cover structure for horizontal double-shell centrifugal pump.
Background
The pump cover and the bearing body bracket of the traditional horizontal double-shell centrifugal pump are positioned through a spigot and connected through bolts. The bolted structure has large assembly errors, the matching surfaces need finish machining, the machining cost is increased, and the pump cover and the bearing body are bolted mutually, so that the pump cover is limited in rigidity, easy to damage after the pump runs for a long time and poor in reliability.
Disclosure of Invention
Aiming at the problems, the utility model makes up the defects of the prior art and provides an integrated pump cover structure for a horizontal double-shell centrifugal pump; the utility model discloses can reduce assembly error, reduce the processing cost, improve the reliability of pump.
In order to achieve the above purpose, the utility model adopts the following technical scheme.
The utility model provides an integral type pump cover structure for horizontal double-shell centrifugal pump, including pump cover, bearing body bracket, its characterized in that, the pump cover with bearing body bracket welding is integrative, be provided with sealed letter in the bearing body bracket, sealed letter with the pump cover bolt joint, be close to in the pump cover bearing body bracket department sets up the balance plate, the outside cover of balance plate is equipped with the balance cover, the balance cover is pressed through balanced cover clamping ring in the pump cover, the balance cover with balanced cover clamping ring all through the bolt joint with the pump cover is connected, sealed letter with the balance plate bolt joint, the sealed letter has mechanical seal part through bolted connection, be provided with the bearing body subassembly on the bearing body bracket.
The beneficial effects of the utility model.
The utility model discloses need not the tang location, reduced assembly error, still reduced the finish machining cooperation surface that needs, reduced the processing cost, rigidity strengthens greatly simultaneously, has improved the reliability of pump.
Drawings
In order to make the technical problem, technical scheme and beneficial effect that the utility model solved more clearly understand, it is right to combine the attached drawing and detailed description mode below the utility model discloses further detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.
Fig. 1 is a sectional view of the structure of the present invention.
The mark in the figure is: the pump comprises a pump cover 1, a bearing body bracket 2, a sealing box body 3, a balance disc 4, a balance sleeve 5, a balance sleeve compression ring 6, a mechanical sealing part 7, a bearing body assembly 8 and a pump shaft 9.
Detailed Description
Shown in the attached drawings, the embodiment provides an integrated pump cover 1 structure for a horizontal double-shell centrifugal pump, which comprises a pump cover 1 and a bearing body bracket 2, wherein the pump cover 1 and the bearing body bracket 2 are welded into a whole.
Be provided with sealing letter body 3 in the bearing body bracket 2, sealing letter body 3 and 1 bolt joint of pump cover, be close to bearing body bracket 2 department in the pump cover 1 and set up balance disk 4, the outside cover of balance disk 4 is equipped with balance sleeve 5, and balance sleeve 5 passes through 6 pressures of balance sleeve clamping ring in pump cover 1. The balance disk 4 and the sealing box body 3 are sleeved on the pump shaft 9 in a matching mode.
The bearing body bracket 2 is provided with a bearing body assembly 8.
The pump cover 1 and the bearing body bracket 2 are welded into an integral piece, the spigot positioning of the traditional structure is not needed, and the assembly error can be reduced. The bolted matching surface does not need to be finished, the processing cost is reduced, the integrity of the bolt is integrally welded, the rigidity is greatly enhanced compared with the rigidity of the traditional bolt connection, and the reliability of the pump is improved.
It should be understood that the above detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can still be modified or equivalently replaced to achieve the same technical effects; as long as satisfy the operation needs, all be in the protection scope of the utility model.
