Abstract
The utility model is a centrifugal pump with an eccentric structure, which includes a pump body, a pump cover as well as impellers. The impeller is positioned inside the pump body; the pump body includes an inner cavity, outlet flange section, a tongue; the outlet flange section is connected with the inner cavity; the inner cavity is a regular cavity with constant radius circle; the pump center and the impeller center have an eccentric distance. The utility model provides a centrifugal pump with an eccentric structure that can reduce production cost with high precision.
Description
(1) technical field
The utility model relates to a kind of centrifugal pump.
(2) background technique
The fed sheet of a media of pump housing collection impeller outlet is also external with it excavationg pump, simultaneously speed can be converted into the pressure energy, this is the main effect of the pump housing, it is different that the quantity of fed sheet of a media is collected between the pump housing and the impeller because each cross section, therefore the area size in each cross section is different, according to the certain rules even variation, near the outlet of the pump housing, area will be big more more.Concrete structure is seen Fig. 1, Fig. 2, and centrifugal pump comprises the pump housing 1, pump cover 3 and impeller 2.Because each cross section of the pump housing is in different size, can only adopt the method for casting that it is created, existing deficiencys such as cost of production height, accuracy of manufacturing is poor, roughness is undesirable like this, all is disadvantageous to aspects such as the overall cost of pump assembly, ride qualities.
(3) summary of the invention
In order to overcome the deficiency of existing centrifugal pump cost of production height, accuracy of manufacturing difference, the utility model provides a kind of can reduce cost of production, the centrifugal pump with eccentric structure that accuracy of manufacturing is high.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of centrifugal pump with eccentric structure, comprise the pump housing, pump cover and impeller, described impeller is positioned at the pump housing, the described pump housing comprises inboard cavity, outlet(discharge) flange section, cut water, described outlet(discharge) flange section is fixedlyed connected with inboard cavity, described inboard cavity such as is at the regular cavity of radius circle, and the center of described pump housing center and impeller has throw of eccentric.
Further, described pump cover comprises pump housing seam and bearing support seam, and is eccentric between pump housing seam center on the described pump cover and the bearing support seam center.
Further again, near the inboard cavity the import of outlet(discharge) flange section, cut water is installed.
Working principle of the present utility model is: pump body structure as shown in Figure 2, by inboard cavity, the outlet(discharge) flange section, cut water is formed, inboard cavity design becomes a regular cavity that waits the radius circle, the flange section is soldered on the inboard cavity, near cut water of the welding import of flange section, just can finish the manufacturing work of the pump housing, the center of the pump housing and the center of impeller are designed to have a throw of eccentric, because the existence of throw of eccentric, to making each cross-sectional sizes between the impeller and the pump housing become different, and the variation in each cross section is an even variation, size according to pump performance can design different throw of eccentric sizes, the generation of throw of eccentric can realize by manufacturing and designing of pump cover, with pump housing seam center (connecting) on the pump cover and bearing support seam center (connecting) decentraction with bearing support with the pump housing, produce a throw of eccentric, just reach eccentric purpose.
The beneficial effects of the utility model mainly show: 1, since the inboard cavity of the pump housing be rule etc. the cylindrical cavity body, can adopt simple processing method manufacturing, the method that need not cast is carried out manufacturing, will significantly reduce manufacturing cost; 2, can improve the manufacturing precision, improve the inner surface roughness, be very favorable to the ride quality of pump assembly.

(5) embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 3, Fig. 4, Fig. 5 and Fig. 6, a kind of centrifugal pump with eccentric structure, comprise the pump housing 1, pump cover 3 and impeller 2, described impeller 2 is positioned at the pump housing 1, the described pump housing 1 comprises inboard cavity 4, outlet(discharge) flange section 5, cut water 6, described outlet(discharge) flange section 5 is fixedlyed connected with inboard cavity 4, and described inboard cavity 4 such as is at the regular cavity of radius circle, and the center of the described pump housing 1 center and impeller 2 has throw of eccentric.Between two arrows of Fig. 4 and Fig. 5 is throw of eccentric.
Pump body structure as shown in Figure 3, by inboard cavity 4, outlet(discharge) flange section 5, cut water 6 is formed, inboard cavity 4 is designed to a regular cavity that waits the radius circle, flange section 5 is soldered on the inboard cavity 4, near cut water 6 of welding 5 imports of flange section, just can finish the manufacturing work of the pump housing, the center of the pump housing and the center of impeller are designed to have a throw of eccentric, because the existence of throw of eccentric, to making each cross-sectional sizes between the impeller 2 and the pump housing 1 become different, and the variation in each cross section is an even variation, size according to pump performance can design different throw of eccentric sizes, the generation of throw of eccentric can realize by manufacturing and designing of pump cover, with pump housing seam 7 centers (connecting) on the pump cover and bearing support seam 8 centers (connecting) decentraction with bearing support with the pump housing, produce a throw of eccentric, just reach eccentric purpose.
Claims (3)
1. centrifugal pump with eccentric structure, comprise the pump housing, pump cover and impeller, described impeller is positioned at the pump housing, the described pump housing comprises inboard cavity, outlet(discharge) flange section, cut water, described outlet(discharge) flange section is fixedlyed connected with inboard cavity, it is characterized in that: described inboard cavity such as is at the regular cavity of radius circle, and the center of described pump housing center and impeller has throw of eccentric.
