Abstract
A kind of nucleus three-level pump body structure belongs to core three-level parts technical field.This nucleus three-level pump body structure includes the pump housing, feed liquor mounting flange, goes out liquid mounting flange, impeller placement room and seal groove.The center of pump housing closing one side is set there are one feed liquor mounting flange, the upper position of the pump housing goes out liquid mounting flange there are one setting, it is set in pump chamber there are one with the inlet of feed liquor mounting flange and going out the impeller that the liquid outlet of liquid mounting flange connect and disposing room, equipped with the seal groove and multiple connection screw thread holes being connected with pump cover on the pump housing of pump chamber opening one side.The pump body structure is simple in structure, and convenient for hot investment casting, processing cost is low, and service life is long.The pump housing is applied on nuclear power domestic at present, mitigates wall thickness on the premise of pressure is ensured, substantially reduces overall weight, is more conducive to be easy to cast and process, cost-effective so as to reach, and drops low consumed purpose.
Description
Technical field
The utility model is related to a kind of nucleus three-level pump body structures, belong to core three-level parts technical field.
Background technology
Nuclear power is a kind of clean energy, and the polluter that nuclear energy power generation discharges flood tide unlike fossil fuel power arrives
In air, therefore nuclear energy power generation will not cause air pollution.Nuclear energy power generation will not generate the titanium dioxide for aggravating global greenhouse effect
Carbon.In the cost of nuclear energy power generation, the ratio shared by fuel cost is relatively low, and the cost of nuclear energy power generation is less vulnerable to international economy feelings
Gesture influences, therefore cost of electricity-generating is stabilization compared with other electricity-generating methods.But applied to the equipment in core field and the technology requirement of parts
It is very high, it not only needs to ensure excellent performance indicator, and should have high reliability and service life, therefore to core three-level
Developmental research is constantly carried out with parts, is improved from structure and technique etc., to meet high-performance, high reliability and height
The requirement in service life is necessary.
The content of the invention
In order to solve the problems in the existing technology, the utility model provides a kind of nucleus three-level pump body structure,
The pump body structure should be simple in structure, and convenient for hot investment casting, processing cost is low, and service life is long.
The technical solution adopted in the utility model is：A kind of nucleus three-level pump body structure, it is solid that it includes the pump housing, feed liquor
Determine flange and go out liquid mounting flange, it further includes impeller placement room and seal groove, and the centre bit of the pump housing closing one side installs
There are one feed liquor mounting flange, the upper position of the pump housing is set there are one going out liquid mounting flange, there are one the lower position of the pump housing is set
Pedestal with pedestal mounting hole, set in pump chamber there are one with the inlet of feed liquor mounting flange and go out liquid mounting flange go out liquid
The impeller placement room of mouth connection, opens in pump chamber and the seal groove being connected with pump cover and multiple connection spiral shells is equipped on the pump housing of one side
Pit.
The feed liquor mounting flange is set there are one inlet and multiple feed liquor flange connecting holes.
It is described go out liquid mounting flange set there are one liquid outlet and it is multiple go out liquid flange connecting hole.
The beneficial effects of the utility model are：This nucleus three-level with pump body structure include the pump housing, feed liquor mounting flange,
Go out liquid mounting flange, impeller placement room and seal groove.The center of pump housing closing one side is set there are one feed liquor mounting flange, is pumped
The upper position of body, which is set, there are one liquid mounting flange is gone out, to be set there are one the inlet with feed liquor mounting flange in pump chamber and goes out liquid
The impeller placement room of the liquid outlet connection of mounting flange, the sealing for being equipped on the pump housing of one side and being connected with pump cover is opened in pump chamber
Slot and multiple connection screw thread holes.The pump body structure should be simple in structure, and convenient for hot investment casting, processing cost is low, and service life is long.It should
The pump housing is applied on nuclear power domestic at present, mitigates wall thickness on the premise of pressure is ensured, substantially reduces overall weight, more
It is cost-effective so as to reach beneficial to being easy to cast and process, low consumed purpose drops.

Specific embodiment
Fig. 1,2 show a kind of nucleus three-level pump body structure figure.In figure, this nucleus three-level pump body structure bag
It includes the pump housing, feed liquor mounting flange 6, go out liquid mounting flange 7, impeller placement room 10 and seal groove 11.The pump housing closes the center of one side
Position is set there are one feed liquor mounting flange 6, and the upper position of the pump housing sets that there are one go out liquid mounting flange 7, the lower position of the pump housing
If there are one the pedestal 3 with pedestal mounting hole 2, set in pump chamber there are one the inlet 5 with feed liquor mounting flange 6 and go out liquid and consolidate
Determine the impeller placement room 10 that the liquid outlet 8 of flange 7 connects, opened in pump chamber close equipped with being connected with pump cover on the pump housing of one side
Sealing groove 11 and multiple connection screw thread holes 1.Feed liquor mounting flange 6 is set there are one inlet 5 and multiple feed liquor flange connecting holes 4.Go out
Liquid mounting flange set there are one liquid outlet 8 and it is multiple go out liquid flange connecting hole 9.
Using above-mentioned technical solution, which is made of with the pump housing four parts, and top connects out liquid for cylinder and consolidates
Determine flange, with liquid outlet, inside goes out liquid flange for 4 circles and fixes even hole, is coolant output department；Lower part is that pedestal is
Cuboid, band are the fixed parts of the pump housing there are two fixing groove；Left part is cylindrical connection feed liquor mounting flange, with into
Liquid mouth is coolant input department；Right part is the main part of the pump housing, passes through 4 connection screw thread holes, seal groove and engine phase
Connection, inside have impeller to dispose room, are the departments of the pump housing.
