Abstract
The utility model belongs to fluid machinery technical field, is specifically related to a kind of vertical type multilevel barrel bag pump of improvement.This device, on existing barrel bag pump basis, the axle sleeve at the two ends up and down of impeller sets coordinates and is provided with the guide bearing body lubricated by medium; Be furnished with pumping lube plant at the lower end oil sump of the bearing housing of bearing housing, and grease input points is higher than the position of its top.The utility model structure is simple, and assembling easily, can be eliminated the quick-fried dead phenomenon of axle caused because of long the radially wobbling of generation of axle preferably simultaneously, and can avoid producing foam in the oil sump of bearing.
Description
Technical field
The utility model belongs to fluid machinery technical field, is specifically related to a kind of vertical type multilevel barrel bag pump of improvement, and be the first-selected pump of the low suction pressure of conveying, its structure is multistage, radial subdivision sectional type housing pump.The pattern of impeller is single-stage radial, and first stage impeller is generally inhalation type impeller.
Background technique
At present, in petrochemical industry in the conveying of liquefied petroleum gas and cryogenic engineering device, because the medium of pump is directly from storage tank and Fractionator Bottom, and in storage tank and fractionation tower, pressure on liquid level is saturation vapour pressure, so device net positive suction head (NPSHa) is very low, and the requirement of these low NPSHa has eliminated the possibility using horizontal pump usually, therefore uses multilevel barrel bag pump widely in petrochemical industry.But, because the cantilevered axle of existing barrel bag pump is long, be easy to generation and radially wobble, the vibration of the quick-fried dead and pump of rotor can be caused; Easily produce oil whip in the oil sump of bearing, have impact on lubrication effect, reduce working life.
Summary of the invention
The purpose of this utility model is to provide a kind of vertical type multilevel barrel bag pump of improvement, the problem of cavitation brought because of low device net positive suction head can be avoided, its structure is simple simultaneously, can eliminate radially wobbling because of the long generation of axle preferably, and can avoid producing foam in the oil sump of bearing.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions: coordinate on the axle sleeve at the two ends up and down of impeller sets and be provided with the guide bearing body lubricated by medium; Be furnished with pumping lube plant at the lower end oil sump of the bearing housing of bearing housing, and grease input points is higher than the position of its top.
What the bearing installed in described bearing housing adopted is one group of face-to-face angular contact ball bearing.
Advantageous Effects of the present utility model is: install guide bearing body additional at the two ends up and down of impeller sets, solves because cantilever axle is out long, easily produces and radially wobbles, and can cause the problems such as the vibration of the quick-fried dead and pump of rotor; An independent pumping lube plant rotated is furnished with in the bearing housing lower end surface of bearing housing, oil is transported to the position higher than bearing, flowing through bearing therefrom again gets back in oil sump, and this structure can ensure to provide lasting clean lubricant oil, avoids retained oil foam.What bearing adopted is one group of face-to-face angular contact ball bearing, can obtain good stability.

Embodiment
Be further elaborated below in conjunction with Fig. 1,2,3 pairs of the utility model.
On existing barrel bag pump basis, the axle sleeve 13 and 2 of the kit upper/lower terminal of impeller 7 coordinates respectively and guide bearing body 12 is installed and 3(refers to Fig. 1,3), guide bearing body 3 and 12 is lubricated by self medium, thus solve because cantilever axle is out long, easy generation radially wobbles, and causes the phenomenon generations such as the vibration of the quick-fried dead and pump of rotor.
Refer to Fig. 2: bearing box assembly lubricating fitting is, be furnished with an independent pumping lube plant rotated in the lower end surface of bearing housing 18.5 and (comprise oil sump 18.1, angular contact ball bearing 18.2, transport pipe 18.3 and bearing housing 18.5), when axle High Rotation Speed, lubricant oil flows through to transport pipe 18.3 from oil sump 18.1 and is transported to position higher than angular contact ball bearing 18.2, flowing through bearing therefrom again gets back in oil sump 18.1, can ensure like this to provide lasting clean lubricant oil, avoid retained oil foam, what this bearing adopted is one group of face-to-face angular contact ball bearing 18.2, thus better stress can be obtained.
Refer to Fig. 1, during installation, (1) by part 13 axle sleeve (in) come to part 25 shaft shoulder place.By part 11 dunnage and part 12 guide bearing body (in) be enclosed within part 13 axle sleeve.(3) part 6 stage casing, part 7 impeller, part 8 stator and part 27 impeller port ring, 28 stage casing chomas, 29 stator chomas, 30 chopped-off head chomas, 31 suction cover chomas are inserted in after assembling on part 25 axle, alignd with part 10 discharge cap seam by final stage stage casing seam, part 5 suction cover outer stopper aligns with stage casing inner stopper.(4) part 4 sleeve is close to the shaft shoulder, successively part 2 axle sleeve is close to sleeve lower end.(5) sucked in diffusing tube by part 3 guide bearing body loading part 32 and be then contained in together on part 5 suction cover and use screw-driving, spindle nose part then appliance 33 self-locking nut is tightened, and is sucked on diffusing tube by part 1 end gland screw-driving at part 32.(6) appliance 9 goes here and there thick stick bolt by part 5 suction cover and part 10 discharge cap tight.(7) part 26 cylindrical tube is tightened in below part 22 section of import and export.(8) part 14 balancing drum cover, part 15 balancing drum, part 16 seal case, part 17 bearing bracket are contained in above part 22 section of import and export successively.(9) bearing box assembly 18, part 19 electric machine support are contained in above part 17 bearing bracket successively.(10) motor is contained in above part 19 electric machine support, then part 20 coupling is loaded onto.
