Abstract
The utility model provides a novel waterproof seal axial -flow pump, including motor casing, pump shaft, bearing frame and water guide cone, pump shaft axial installation is in the motor casing, water guide cone passes through the bolt fastening at electric chassis bottom fixed connection bearing frame between water guide cone and the motor casing, the bearing frame is passed to pump shaft one end and water guide cone is connected with impeller seat, installs the impeller on impeller seat install the bearing between bearing frame and the pump shaft the organic seat that seals of installation between water guide cone and the pump shaft. The utility model has the beneficial effect of simple structure, it is sealed effectual, prolonged axial -flow pump life.
Description
Technical field
This utility model belongs to axial-flow pump technical field, especially relates to a kind of novel seal waterproof axial-flow pump.
Background technology
Axial-flow pump is conveying liquid or the machinery making fluid pressurization, axial-flow pump is mainly used to carry liquid to include water, oil, acid & alkali liquid, emulsion, suspended emulsion and liquid metal etc., also liquid can be carried, admixture of gas and the liquid containing suspended solids, the axial-flow pump commonly used at present adopts traditional mechanical seal such as single sealing gasket or sealing ring, in use this traditional mechanical seal easily connects loosening and comes off, and once mechanical connection loosens, medium enters and seals chamber, filler rapid wear can be caused, seal failure, now must change axial flow pump body guarantee equipment properly functioning.
Utility model content
The purpose of this utility model is to overcome prior art not enough, it is provided that a kind of novel seal waterproof axial-flow pump, its simple in construction, good sealing effect, extends axial-flow pump service life.
The technical solution of the utility model is: a kind of novel seal waterproof axial flow axial-flow pump, including motor casing, pump shaft, bearing block and water guide cone, described pump shaft is axially mounted in motor casing, described water guide cone is bolted on bottom motor casing, fixed connection shaft bearing between described water guide cone and motor casing, described pump shaft one end is connected to impeller base through bearing block and water guide cone, impeller base is provided with impeller, between described bearing block and pump shaft, bearing is installed, organic envelope seat is installed between described water guide cone and pump shaft.
Further, it is matched in clearance between described machine envelope seat and pump shaft.
Further, between described machine envelope seat bottom portion and pump shaft, it is connected to outside framework oil seal.
Further, sealing at described machine and be also installed with mechanical seal between seat and bearing block, described mechanical seal is sleeved on outside pump shaft.
This utility model has the advantage that and has the benefit effect that owing to adopting technique scheme, organic envelope seat is installed between described water guide cone and pump shaft, the effect sealing seat at machine is that solid mechanical seals, and ensure that mechanical seal is without prejudice, ensure that axial-flow pump in use mechanical seal does not get loose, not landing, improves sealing effectiveness.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is elaborated.
Such as Fig. 1, shown in structural representation of the present utility model, this utility model provides a kind of novel seal waterproof axial flow axial-flow pump, including motor casing 1, pump shaft 2, bearing block 3 and water guide cone 4, described pump shaft 2 is axially mounted in motor casing 1, described water guide cone 4 is bolted on bottom motor casing 1, fixed connection shaft bearing 3 between described water guide cone 4 and motor casing 1, described pump shaft 2 one end is connected to impeller base 5 through bearing block 3 and water guide cone 4, impeller base 5 is provided with impeller 6, between described bearing block 3 and pump shaft 2, bearing 7 is installed, organic envelope seat 8 is installed between described water guide cone 4 and pump shaft 2.
It is matched in clearance between described machine envelope seat 8 and pump shaft 2.Seal bottom seat 8 at described machine and be connected to outside framework oil seal 9 between pump shaft 2.Sealing at described machine and be also installed with mechanical seal 10 between seat 8 and bearing block 3, described mechanical seal 10 is sleeved on outside pump shaft 2.
The work process of this example: the novel seal waterproof axial flow axial-flow pump that this utility model provides, organic envelope seat 8 is installed between described water guide cone 4 and pump shaft 2, the effect sealing seat 8 at machine is that solid mechanical seals 10, and ensure that mechanical seal 10 is without prejudice, ensure that axial-flow pump in use mechanical seal 10 does not get loose, not landing, improve sealing effectiveness, when mechanical seal 10 changed by needs, only machine need to seal seat 8 to be disassembled by water guide cone 4, being sleeved on pump shaft 2 by new mechanical seal 10, it is convenient to change, simple to operate.Seal bottom seat 8 at described machine and be connected to outside framework oil seal 9 between pump shaft 2, further increasing the sealing effectiveness of axial-flow pump.
Above an embodiment of the present utility model is described in detail, but described content has been only preferred embodiment of the present utility model, it is impossible to be considered for limiting practical range of the present utility model.All equalizations made according to this utility model application range change and improvement etc., all should still belong within patent covering scope of the present utility model.
