Abstract
The utility model belongs to be suitable for petrochemical, the drain of the centrifugal pump pump body of use in the fields such as coal industry, chemical fibre, power plant, environmental engineering, seawater desalination, concretely relates to modified pump body flowing back structure. The flowing back flange that is fixed with the fluid -discharge tube is connected in the below of pump body flowing back interface to this device, and the lining has sealed the pad between pump body flowing back interface and flowing back flange, corresponds interval equipartition screw at the edge of pump body flowing back interface and flowing back flange, with hexagon head bolt with pump body flowing back interface and flowing back flange joint. The utility model discloses simple structure has solved the problem that drain line damaged easily when installation and change spare parts, reduce the probability that drain line leaked, installs the maintenance simultaneously than traditional flowing back form convenient and fast.
Description
Technical field
This utility model belongs to the fields such as applicable petrochemical industry, Coal Chemical Industry, chemical fibre, power plant, environmental project, desalinization
Used in centrifugal pump body pumping equipment, and in particular to a kind of improved pump housing drainage structure.
Background technology
Conventional centrifugal pump pump housing discharge opeing form is directly welded on the pump housing for drain line or blocks pump housing discharge opeing with plug
Mouthful, which has the disadvantage inflammable and explosive, and when the operating mode such as High Temperature High Pressure is used, the structure using plug is unreliable；Drain line is direct
Although being welded on the structure reliability of the pump housing, the pump housing in hoisting process as drain line is non-dismountable, drain line diameter
It is less, easily cause drain line and damage pipeline the problems such as deform.Drain line need to be changed together by the pump housing when spare part is changed,
Sometimes result in the problem that pump housing drain line is not connected with user scene drain line, the unnecessary fiber crops of cause the user
It is tired.It is therefore desirable to improving the discharge opeing form of the pump housing.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of improved pump housing drainage structure, can be applicable to inflammable easy
It is quick-fried, in the operating mode such as High Temperature High Pressure, the drainage structure have simple structure, easy processing, easily assembling, high temperature resistant, high pressure, sealing can
By, the characteristic such as easy to maintenance.
The purpose of this utility model is achieved through the following technical solutions：It is connected below pump housing discharge opeing interface
There is the discharge opeing flange of discharging tube, sealing gasket is lined between pump housing discharge opeing interface and discharge opeing flange.
In pump housing discharge opeing interface screw uniformly at intervals corresponding with the edge of discharge opeing flange, with hexagon-headed bolt by pump housing discharge opeing
Interface is connected with discharge opeing flange.
Advantageous Effects of the present utility model are：Pump housing discharge opeing interface and discharge opeing flange are isolating construction, therefore are changed
Drain line need not be changed during pump housing spare part, and surface is higher using machining positional precision, it is ensured that pump housing discharge opeing
The concordance of position when pipeline is installed again, when the pump housing is changed, drain line correctly can connect with user scene drain line.It is logical
Cross above-mentioned improvement and solve the problems, such as that drain line is easily damaged when installing and change spare part, reduce the several of drain line leakage
Rate, while install safeguarding more convenient and swift than traditional discharge opeing form.
Description of the drawings
This utility model is further described with enforcement below in conjunction with the accompanying drawings.
Fig. 1 is traditional discharge opeing form structure schematic diagram.
Fig. 2 is discharge opeing form structure schematic diagram after improving.
In figure：Base 1, the pump housing 2, hexagon-headed bolt 3, discharging tube 4, sealing gasket 5, discharge opeing flange 6.
Specific embodiment
2 discharge opeing interface of the pump housing is connected with the leakage fluid dram of the pump housing 2 by discharge opeing flange 6 in underface, discharge opeing flange 6 and pump
Body 2 is connected with hexagon-headed bolt 3, therefore need not change discharging tube 4 when changing pump housing spare part.The company of discharge opeing flange 6 and the pump housing 2
Position piece surface is connect using machining, positional precision is higher, it is ensured that the one of position when pump housing discharging tube 4 is installed again
Cause property, therefore discharging tube 4 can correctly connect with user scene drain line when changing the pump housing 2.Discharge opeing flange 6 is adopted with the pump housing 2
Sealing gasket 5 is sealed, sealing gasket 5 according to the different reliability for ensureing sealing using different materials of applying working condition, discharge opeing flange 6 with
Discharging tube 4 is adopted and is welded to connect.
Claims (1)
1. a kind of improved pump housing drainage structure, is characterized in that：Discharging tube is fixedly connected with below pump housing discharge opeing interface
Discharge opeing flange, is lined with sealing gasket between pump housing discharge opeing interface and discharge opeing flange；On pump housing discharge opeing interface and the side of discharge opeing flange
Pump housing discharge opeing interface is connected with discharge opeing flange by the corresponding screw uniformly at intervals of edge with hexagon-headed bolt.
