Abstract
The utility model relates to a test reactor is with open water pump structure, apron (13) links with the pump body (1), and install on axle (5) axle sleeve (4), and impeller (2) are leaned on on axle sleeve (4) and are adopted impeller nut (12) to fix on axle (5), and bush (6) suit is on axle sleeve (4), and bush (6) are leaned on on pump cover (3), and the impeller is open impeller, and is the clearance between impeller and the apron 0.3 0.8mm. Direct trompil on the pump cover, the water under high pressure that uses pump itself to go out impeller exit territory washes as packing seal. This water pump simple structure, simple to operate. The important technical foundation and the guarantee of the design of nuclear power station water pump, have higher economic value and long -range development prospect.
Description
Technical field: the utility model relates to a kind of test reactor opened water pump configuration.
Background technology:
The most domestic nuclear power station of greatly developing, present nuclear power station is more and more with pump.But
The pump belonging to the intellectual property being our autonomous Design is little, especially under liquid under delivery pump and liquid
Spent resin delivery pump, because the particularity of this kind of pump configuration, is to be immersed under liquid to work, and uses
Condition rather harsh, and maintenance inconvenience, also the use cycle in power station is the longest.This just requires
The security of pump is high, and service life is long, and maintenance cycle is long.This kind of power station pump is in our country
There is presently no ready-made pump, be mostly to require, from external import, to come relative to this pump itself
Saying, cost is at a relatively high.
Summary of the invention: the purpose of this utility model be to provide simple in construction, stable performance, reliable,
A kind of test reactor opened water pump configuration of safety.The technical solution of the utility model is: test
Heap opened water pump configuration, cover plate (13) is connected with the pump housing (1), and axle sleeve (4) is arranged on axle (5)
On, impeller (2) leans against axle sleeve (4) and above and uses impeller nut (12) to be fixed on axle (5), lining
Set (6) is sleeved on axle sleeve (4), and lining (6) leans against on pump cover (3), loads onto by lining (6)
Packing seal assembly (15), the pump housing (1) uses securing member to be fixed on pump cover (3), couples parts
(8) being arranged on pump cover (3), the other end coupling parts (8) is arranged on base plate (10), axle
Bearing portion part (7) is fixed on base plate (10) through axle (5) and couples on parts (8), hitch (11)
Being fixed on parts of bearings (7), one end of discharge pipe parts (9) is fixed on the outlet of the pump housing (1)
End, the other end of discharge pipe parts (9) is fixed on base plate (10) through base plate (10).
Impeller (2) is that (having gap between impeller (2) and cover plate (13), gap width is unshrouded impeller
0.3-0.8mm).With through hole on pump cover (3).
The course of work of the present utility model is: axle (5) rotates impeller (2) and rotates,
Water sucks from the suction inlet of suction casing (1), is discharged to spue via the discharge opening of the pump housing (1)
Duct member (9), then by discharge pipe parts (9) excavationg pump outside.
Technological merit of the present utility model with good effect is:
1, the utility model is as shown in Figure 1, and this pump configuration is simple, easy for installation, does not has
Complicated component structural.
2, the utility model is as shown in Figure 1, and the utility model have employed unshrouded impeller, should
Plant impeller channel little, be designed to unshrouded impeller easy to process.
3, the utility model is as it is shown in figure 1, this kind of pump is inserted directly in spent resin liquid,
Asking sealing quite strict, machining accuracy is high.
4, the utility model advanced and reasonable design, for ensureing in 95%～105% flow region
Stable, efficient, the hydraulic model of pump is optimized, and reduces hydraulic loss, thus carries
High overall efficiency.
5, the material of the parts of the main body of the utility model pump portion is corrosion resistant stainless
Steel part.
6, the utility model is as shown in Figure 1, and direct perforate on pump cover, with the impeller of pump own
The water under high pressure of exit region is that packing seal is rinsed.
Accompanying drawing illustrates:
Fig. 1 is the utility model one test reactor opened water pump configuration schematic diagram
Fig. 2 is the utility model pump portion enlarged diagram
Detailed description of the invention:
A kind of test reactor opened water pump configuration as shown in Figure 1, cover plate 13 is connected with the pump housing 1
Connecing, axle sleeve 4 is contained on axle 5, is leaned against by impeller 2 and fixes with impeller nut 12 on axle sleeve 4
On axle 5.Lining 6 is enclosed within axle sleeve 4, leans against on pump cover 3, filling near lining 6
Upper packing seal assembly 15, is tightened against the pump housing 1 securing member on pump cover 3, then will couple
Parts 8 are associated on pump cover 3, and the other end coupling parts 8 is contained on base plate 10, then by axle
Bearing portion part 7 is fixed on base plate 10 through axle 5 and couples on parts 8, the most again by hitch
11 are fixed on parts of bearings 7.Again one end of discharge pipe parts 9 is fixed on the pump housing 1
The port of export, the other end is through base plate 10 and is fixed on base plate 10.
This pump pump portion under water or works under liquid spent resin liquid.Zero of the main body of pump portion
The material of part all uses stainless steel part to be processed.
As in figure 2 it is shown, impeller 2 is designed as unshrouded impeller, between impeller 2 and cover plate 13
Gap is 0.3-0.8mm.
Direct perforate on pump cover 3, is that filler is close with the water under high pressure in pump impeller outlet region own
Sealing assembly 15 is rinsed.
