Abstract
The utility model provides a rolling bearing self-cooling type submerged pump. The rolling bearing self-cooling type submerged pump is formed by a pump body (1), a pump cover (2), an impeller (3), a pump shaft (4), a mechanical sealing cylinder (5), a mechanical seal (6), a supporting pipe (7), a bearing frame (8) and a rolling bearing (9). The rolling bearing self-cooling type submerged pump is characterized in that a liquid outlet cavity channel of the pump body (1) is connected with a liquid conveying pipe (12); the mechanical sealing cylinder (5) is provided with a cooling liquid inlet pipe (52) which is connected with the liquid conveying pipe (12); the supporting pipe (7) which is connected with the liquid conveying pipe (12) close to a bearing frame base plate (81) is provided with a cooling fluid feeding pipe (72) which faces the pump shaft (4); liquid flushing cooling is performed on the pump shaft (4), the bearing frame base plate (81) and a frame oil seal (84) through the cooling fluid feeding pipe (72) and accordingly the rolling bearing (9) can be cooled.
Description
technical field
What the present invention relates to is centrifugal Under Water Pumps.
background technique
Centrifugal Under Water Pumps comprises that the pump housing 1, pump cover 3, impeller 2, pump shaft 4, mechanical seal cylindrical shell 5, mechanical seal 6, support tube 7, bearing bracket stand 8, rolling bearing 9, motor 10 form.According to the difference of operating mode and performance requirement, its concrete structure is also identical to some extent.
The centrifugal Under Water Pumps of above-mentioned prior art is provided with rolling bearing cover for seat 82 and main shaft rolling bearing 9 on the chassis 81 of bearing bracket stand 8, is provided with outside framework oil seal 84 and coordinates the inner chamber of rolling bearing 9 is sealed with main shaft on 81 axis holes 83 of the chassis of bearing bracket stand 8.Can produce frictional heat and rolling bearing 9 self also can produce frictional heat because outside framework oil seal 84 coordinates with main shaft 4 pivoting frictions, rolling bearing 9 is heated and can not get coolingly, affects working life, increases maintenance cost.
Model utility content
The purpose of this utility model is to improve for above-mentioned the deficiencies in the prior art, provides a kind of manufacture easy, and made pump shaft easy to maintenance and rolling bearing obtain cooling Under Water Pumps.
The utility model rolling bearing self cooled Under Water Pumps is by the pump housing 1, pump cover 2, impeller 3, pump shaft 4, mechanical seal cylindrical shell 5, mechanical seal 6, support tube 7, bearing bracket stand 8, rolling bearing 9, motor 10 forms, on the chassis 81 of bearing bracket stand 8, be provided with rolling bearing cover for seat 82 for main shaft rolling bearing 9 is installed, on 81 axis holes 83 of the chassis of bearing bracket stand 8, being provided with outside framework oil seal 84 coordinates the inner chamber of rolling bearing 9 is sealed with main shaft, it is characterized in that being connected with indusion tube 12 on the fluid cavity of the pump housing 1, offer cooling liquid inlet opening 51 and liquid inlet pipe 52 at mechanical seal cylindrical shell 5, liquid inlet pipe 52 is connected with indusion tube 12, carry out cooling by interior the high-pressure medium introducing mechanical seal cylindrical shell 5 of the pump housing 1 fluid cavity to mechanical seal 6, on the support tube 7 near 81 places, bearing bracket stand chassis, be provided with cooling liquid fluid ozzle 73 and the feed pipe 72 of subtend pump shaft 4, have outage 70 in the underpart of support tube 7, feed pipe 72 is connected with indusion tube 12, the high-pressure medium of the fluid cavity of the pump housing 1 is introduced, by fluid ozzle 73, pump shaft 4 and 81 places, bearing bracket stand chassis, outside framework oil seal 84 are rushed to liquid cooling but, thereby it is cooling that rolling bearing 9 is obtained.
The utility model is manufactured easy to be easy to maintenance, can make pump shaft and rolling bearing obtain cooling, thereby improves working life, reduces maintenance.
