Abstract
The utility model relates to a compact submerged pump and belongs to the technical field of a high-temperature fluid conveying machinery. The pump body (4) of the submerged pump is provided with a section of liquid outlet channel (5) while the complex structures such as liquid outlet pipe, flange, and the like are cancelled. The liquid outlet pipe is sufficiently close to a support part so the radial size of the pump is small enough in order to meet the demand of assembling through a small-bore baseboard. The submerged pump is also suitable for the occasions for transporting common medium under a limited assembling condition. A middle support tube and the liquid outlet pipe are separated but tightly close to each other so the structure is compact. When the pump runs, the liquid outlet pipe is filled with the high temperature medium and is tightly contacted with a center support tube so the temperature of the liquid outlet pipe and the support tube are almost the same, the thermal expansion quantities are almost the same, the axial uniform expansion is almost eliminated and the service life of a sliding bearing is prolonged.
Description
Technical field
The utility model relates to a kind of compact type Under Water Pumps, and it belongs to the high temperature fluid technical field of conveying machinery.
Background technique
The multiple operating mode occasion that needs to carry high temperature media is arranged in the petrochemical industry, the most melting point height of these high temperature medias, the solidifying point height, easily crystallization after the reduction temperature is as media such as phthalic anhydride, high-temperature molten salt, pitch, liquid-state sulfurs.Traditional design adopts bend pipe to change into axial discharge by the radial flow medium that the pump housing is derived more, does the radial dimension that has increased pump like this, can't guarantee uniform thermal expansion amount fully.In order to guarantee that medium temperature does not descend or do not produce crystallization, often on the fluid pipeline, insulation jacket be set, feeding insulation steam is incubated, simultaneously in order to prevent that temperature from reducing the crystalline material that produces and condensing at the gap location of sliding bearing, destroy the normal use of sliding bearing, also to feed steam and be incubated in the body of sliding bearing outer installment insulation jacket.So, increase the insulation jacket of many places and loaded down with trivial details steam pipeline system, added the selflubricating flushing line of pump itself etc., made pump structure become complicated, increased the difficulty of use and maintenance maintenance.
The model utility content
The purpose of this utility model is in order to solve the technical problem of above-mentioned existence, to provide a kind of fluid pipeline and sliding bearing place all to need not to adopt the insulation jacket device, compact type Under Water Pumps simple in structure again.
The technological scheme that the utility model is adopted for achieving the above object is:
A kind of compact type Under Water Pumps, it mainly comprises the pump housing that pump cover, inside are equipped with pump shaft, drives impeller is installed below one, and the pump housing is connected with support column, and a drain pipe is fixedly mounted on a side of support column; The described pump housing is provided with a fluid runner, and the bottom liquid entering hole of fluid runner is over against the tangential liquid outlet of described impeller, and the top liquid outlet is connected with described drain pipe.
Described support column and drain pipe are integrally welded with flange together.
Axle sleeve of fixed installation on the described pump shaft, axle sleeve becomes to be rotatably assorted with axle bush in being fixedly mounted on the body of sliding bearing.
Described the body of sliding bearing is provided with from flushing hole.
The beneficial effects of the utility model are: this Under Water Pumps has been cancelled labyrinths such as fluid bend pipe and flange, with fluid pipeline and supporting part close enough, reaches the purpose that changes the liquid flow path direction by pump housing Way out is changed.Make the radial dimension of pump enough little, can satisfy the requirement that the user adopts small-bore base plate to install, so this kind pump structure also is applicable to carries generic media but to the conditional occasion of installation conditions.Intermediate support pipe and drain pipe are separated, but abut against together, compact structure during pump operation, is full of high temperature media in the drain pipe, and central support tube and its tight contact, the temperature of drain pipe and support tube is basic identical like this, and thermal expansion amount is basic identical, and the thermal expansion force of generation is basic identical, basically eliminate axial differential expansion, prolong the working life of sliding bearing.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model;
Embodiment
As shown in Figure 1, a kind of compact type Under Water Pumps, it mainly comprises the pump housing 4 that pump cover 1, inside are equipped with pump shaft 13, drives impeller 3 is installed below one, and the pump housing 4 is connected with support column 6, and a drain pipe 7 is fixedly mounted on a side of support column 6; The pump housing 4 is provided with a fluid runner 5, and the radial flow of medium is changed into axial flow, and liquid outlet and pump body close enough guarantee that the overall radial dimension of pump liquid bottom realizes minimum; The bottom liquid entering hole of fluid runner 5 is over against the tangential liquid outlet of impeller 3, and the top liquid outlet is connected with drain pipe 7.Impeller 3 adopts chuck 2 forms to carry out secure fixation.Support column 6, drain pipe 7 weld together with flange 10, and both are separated but abut against together; Axle sleeve 8 is fixed on the pump shaft 13, and axle bush 9 is fixed in the body of sliding bearing 12, and axle sleeve 8 is rotatably assorted for 9 one-tenth with axle bush in being fixedly mounted on the body of sliding bearing 12.The body of sliding bearing 12 is same closely close with drain pipe 7, and fluid pipeline 7 and sliding bearing 12 places all need not to adopt the insulation jacket device.During pump operation, be full of high temperature media in the drain pipe 7, and support tube 6 and sliding bearing 12 all with its tight contact, the temperature of drain pipe 7, support tube 6 and sliding bearing 12 is basic identical like this, thermal expansion amount is basic identical, the thermal expansion force that produces is basic identical, eliminates axial differential expansion basically, prolongs the working life of sliding bearing 12.When carrying cleaning medium, by on the body of sliding bearing 12 from flushing hole 11, directly sliding bearing 12 is carried out from flushing, it is unnecessary from flushing line to need not to dispose, and makes simple in structure, easy to maintenance.
