Abstract
The utility model discloses a pump body structure for a service water pump for a nuclear power plant. The pump body structure comprises a connecting pipe, an outlet elbow, a pump seat, a pump cover and a motor seat, wherein the upper part of the wall surface of the pump seat is provided with a water outlet, and a transverse drainage pipe is connected to the water outlet; the upper end of the connecting pipe stretches into the middle of an inner cavity of the pump seat; the outlet elbow is arranged in the inner cavity of the pump seat; the water outlet end and the lower end of the outlet elbow are respectively connected with the drainage pipe of the pump seat and the upper end of the connecting pipe; the upper part of a pipe wall of the outlet elbow is provided with an upper straight pipe; the lower end of the pump cover is provided with a lower straight pipe; the lower end of the lower straight pipe is connected with the upper straight pipe on the elbow; and the motor seat, the pump cover and the pump seat are sequentially superposed from top to bottom and are connected together through a plurality of connecting bolts. By the pump body structure for the service water pump for the nuclear power plant, working parts below the base of the pump can be maintained under the condition that the outlet pipeline is not detached, and the maintenance time of a rotor part is greatly shortened.
Description
Technical field
The utility model relates to a kind of house service pump that is used for nuclear power station, is specifically related to a kind of pump body structure that is used for the house service pump of nuclear power station.
Background technique
The working medium that is used for the essential service water pump of nuclear power station is to contain sea of sand water.The major function of essential service water pump in nuclear power station is that the liquid heat that the component cooling water system transmission comes finally is transferred to seawater, and extracting seawater is cooled off component cooling water in other words.It is as the ultimate heat sink of nuclear island, and its significance is self-evident.
The existing house service pump that is used for nuclear power station is vertical, major axis centrifugal pump, and the major axis pump of general structure will overhaul impeller rotor part must take rising pipe apart, could pull the rotor part of pump bottom, is unfavorable for very much site examining and repairing.
Summary of the invention
The purpose of the utility model is in order to overcome the deficiency of existing technology; A kind of pump body structure that is used for the house service pump of nuclear power station is provided; It can overhaul the workpiece below the basis of pump under the situation of not dismantling the outlet bend pipe, has shortened the repair time of rotor part greatly.
The technological scheme that realizes above-mentioned purpose is: a kind of pump body structure that is used for the house service pump of nuclear power station, comprise connecting tube, outlet bend pipe, pump seat, pump cover and motor cabinet, wherein,
The upper end of said connecting tube reaches the inner chamber middle part of said pump seat;
The wall top of said pump seat is offered a drain opening and is connected a horizontal waste pipe at this drain opening place;
Said outlet bend pipe is located in the inner chamber of pump seat; Dock with the inner of the waste pipe of said pump seat the waterexit end of this outlet bend pipe; Lower end of this outlet bend pipe is connected with the upper end of said connecting tube, and it is one coaxial and with the last straight tube of diameter with said connecting tube that the tube wall top of this outlet bend pipe is provided with;
The lower end of said pump cover be provided with one with said outlet bend pipe on last straight tube coaxial and with the lower straighttube of diameter, the lower end of this lower straighttube is connected with last straight tube on the said bend pipe;
Said motor cabinet, said pump cover and said pump seat are stacked successively from top to bottom and link together through some connecting bolts.
The pump body structure of the above-mentioned house service pump that is used for nuclear power station, wherein, the said pump housing also comprises three pump case groups that are connected in series and the import loudspeaker that are connected to said connecting tube lower end in turn.
The technological scheme of the pump body structure of the house service pump that is used for nuclear power station of the utility model; Adopt whole Drawing-Core structure; Promptly can be under the situation of not dismantling outlet conduit; The workpiece that will be positioned at pump seat inside and bottom pulls out from the upper end-hole of pump seat and overhauls, thereby has shortened the repair time of rotor part greatly.
Description of drawings
Fig. 1 is the schematic representation of the pump body structure of the house service pump that is used for nuclear power station of the utility model.
Embodiment
In order to understand the technological scheme of the utility model better, below through embodiment particularly and combine accompanying drawing at length to explain:
See also Fig. 1, a kind of pump body structure that is used for the house service pump of nuclear power station of the utility model comprises import loudspeaker, three pump case groups, connecting tube 1, outlet bend pipe 2, pump seat 3, pump cover 4 and motor cabinets 5, wherein:
The upper end of connecting tube 1 reaches the inner chamber middle part of pump seat 1;
The upper end of pump seat 3 is provided with a mounting flange, and the wall top of this pump seat 3 is offered a drain opening and connected a horizontal waste pipe 31 at this drain opening place, and the outer end of this waste pipe 31 connects outlet conduit 32;
The lower end of motor cabinet 5 is provided with outer ring flat-plate 50;
Three pump case groups are chopped-off head pump case group, secondary pump case group and final stage pump case group and the lower end that is connected in series in connecting tube 1 from bottom to top successively;
The import loudspeaker are arranged on the lower end of chopped-off head pump case group.
The pump body structure of the house service pump that is used for nuclear power station of the utility model; As long as unclamp the connecting bolt 50 between pump seat 3, pump cover 4 and the motor cabinet 5; Can be under the situation of not dismantling outlet conduit 32; Can extract the workpiece of pump cover 4 bottoms out, it is overhauled, shorten maintenance and maintenance time greatly rotor part.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not with the qualification of doing the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model the above embodiment's variation, modification.
