Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Accompanying drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that retouched
The embodiment stated is a part of embodiment of the utility model, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to
The scope of the utility model protection.
Fig. 1 is the structural representation of the utility model thrust disc embodiment one, and the thrust disc is specially to be applied to inverse circulation
The thrust disc of the impeller end of type-RA type canned motor pumps, specifically, inverse circular form-RA type canned motor pumps are usually provided with two thrust discs,
The thrust disc of the present embodiment refers specifically to apply the thrust disc close to impeller one end, as shown in figure 1, the thrust disc of the present embodiment can
With including：Thrust disc body 1, keyway 2 and multiple guiding gutters 3, wherein, the thrust disc body 1 is ring-shaped cylinder, the edge of keyway 2
The short transverse of thrust disc body 1 is arranged on the inner surface of the thrust disc body 1, and the keyway 2 is used to connect into line unit, multiple to lead
Chute 3 is evenly distributed on the upper surface of the thrust disc body 1, and each guiding gutter 3 is the appearance from the thrust disc body 1
Groove of the face to inner surface.
Specifically, when being arranged on the thrust disc of the present embodiment in inverse circular form-RA type canned motor pumps, the upper surface is (i.e.
It is provided with the one side of guiding gutter) towards sliding bearing.In the inverse circular form-RA type canned motor pumps that the thrust disc of the present embodiment is applied
Portion cool down and lubrication sliding bearing the medium pumped for this against circular form-RA type canned motor pumps of lubricating fluid, you can be to liquefy
Oil gas, the lubricating fluid is by sliding bearing and the guiding gutter of the thrust disc, main shaft of the thrust disc in inverse circulation shield pump
Drive lower rotation at a high speed to produce centrifugal force, can be effectively increased and (cross liquid by the lubrication flow quantity of sliding bearing and the thrust disc
Amount) so that effectively cooling and lubrication sliding bearing and thrust disc.
Optionally, the number of multiple guiding gutters is relevant with inverse circular flow.Specifically, because liquefied gas easily gasifies, it is main
It is the saturated vapour pressure height under C3, C4, normal temperature to want composition, in order to prevent liquefied gas from producing gasification in course of conveying, it is ensured that
Inverse circulation shield pump is normally run, it is necessary to which inverse circular flow is defined, and inverse circular flow is to the cunning in inverse circulation shield pump
Dynamic bearing is lubricated and very important effect is played in motor cooling, if inverse circular flow is not enough, motor cavity liquid easily gasifies,
So that bearing lubrication is bad, bearing inordinate wear is caused, inverse recycle stream value is to be converted into heat energy according to loss of electric machine power, is made
What inverse circular flow temperature rise was determined no more than boundary.And the number of the guiding gutter of the thrust disc of the present embodiment can be inverse according to this
The actual value of circular flow is flexibly chosen, specifically, inverse circular flow is bigger, the number of the guiding gutter of thrust disc is got over

Optionally, the sectional area of each guiding gutter 3 is equal.Specifically, the depth and width phase of each guiding gutter 3
Deng.Because each guiding gutter 3 is from the outer surface of the thrust disc body 1 to the groove of inner surface, so each guiding gutter 3
Length be also equal.
Optionally, the sectional area of multiple guiding gutters 3 is relevant with inverse circular flow.Specifically, can also be according to inverse recycle stream
Value flexibly sets the sectional area of guiding gutter, and inverse circular flow is bigger, and the sectional area of the guiding gutter of thrust disc is bigger, on the contrary, inverse
Circular flow is smaller, and the sectional area of the guiding gutter of thrust disc is smaller.
Optionally, the material of the thrust disc is 304 stainless steels.Specifically, material for 304 stainless steels thrust disc compared to
Material is the sliding bearing of graphite, and it is not easy to wear, so, the sectional area for the guiding gutter being opened on thrust disc will not be due to making
Reduced with abrasion, so as to maintain stable sufficient mistake liquid measure.
Optionally, multiple guiding gutters 3 are located at the both sides of keyway 2.
Optionally, the number of multiple guiding gutters 3 can for 4,5 or 6.Thrust disc as shown in Figure 1, its thrust disc is led
Chute number is 4.Fig. 2 be the utility model thrust disc embodiment two structural representation, thrust disc as shown in Figure 2, its
The guiding gutter number of thrust disc is 5.
It should be understood that the thrust disc of the present embodiment can be used on the basis of existing thrust disc as shown in Figure 3
The special equipment of cutting metal mills out guiding gutter as shown in the figures 1 and 2, and its acquisition modes is simple and convenient.
The thrust disc of the present embodiment, the thrust disc is the thrust disc of the impeller end applied to inverse circular form-RA type canned motor pumps,
The thrust disc specifically includes thrust disc body, keyway and multiple guiding gutters, and the upper surface of the thrust disc is evenly arranged with multiple lead
Chute, and each guiding gutter is from the outer surface of the thrust disc body to the groove of inner surface.Due in thrust disc
Upper surface is provided with multiple guiding gutters, so as to increase the sliding bearing for the inverse circular form-RA type canned motor pumps for being provided with the thrust disc
With the mistake liquid measure of thrust disc, with effectively lubricating and sliding bearing and thrust disc can be cooled down, and then extend sliding bearing and thrust
The service life of disk.
Have, service life can extend to more than 1200 hours by original 200 hours, effectively reduce canned motor pump
Maintenance frequency and cost.
Fig. 4 is structural representation of the utility model against circular form-RA type canned motor pump embodiments, as shown in figure 4, this implementation
Inverse circular form-RA type the canned motor pumps of example include：Impeller 4, main shaft 5, sliding bearing 6 and thrust disc as shown in Figure 1 or 2,
Wherein, thrust disc is connected by keyway 2 with the key of main shaft 5 of inverse circular form-RA type canned motor pumps, the upper surface of thrust disc body 1 with
The sliding bearing 6 of inverse circular form-RA type canned motor pumps is contacted, as shown in figure 4, thrust disc is positioned close to the side of impeller 4.
Rotation produces centrifugal force to the thrust disc at a high speed under the drive of the main shaft 5 of inverse circulation shield pump, can be effectively increased
By the mistake liquid measure of sliding bearing 6 He the thrust disc, so that effectively cooling and lubrication sliding bearing 6 and thrust disc.
Inverse circular form-RA type the canned motor pumps of the present embodiment install the thrust disc for being provided with guiding gutter, can increase slip
The mistake liquid measure of bearing and thrust disc, effectively lubricating and cooling sliding bearing and thrust disc, and then extend sliding bearing and thrust
The service life of disk.
