Abstract
The utility model discloses a reverse cycle shield pump cycle flow measuring device, which comprises a shield pump, wherein a reverse cycle outlet end of the shield pump is provided with a flange. One end of the flange is connected with a flow measuring device, and the measuring device comprises two valves, a flow meter and a pressure meter. The reverse cycle shield pump cycle flow measuring device is simple in structure and convenient to use.
Description
Technical field
The utility model relates to a kind of measuring device, particularly a kind of contrary circulation canned motorpump circular flow measuring device, and it comprises that a canned motorpump and is arranged on the flange on the said canned motorpump outlet end.
Background technique
The staor winding of existing canned motorpump places sealing metal cylindrical shell interior shielded motor driving, pump case to link to each other with flange seal with the drive motor shell respectively with the rotor winding, has cancelled the pump of pump shaft movable sealing structure.Be suitable for carrying precious liquid or be with radioactive liquid.
Canned motorpump connects together pump and motor, and the rotor of motor and the impeller of pump are fixed on the same axis, utilizes housing that the rotor and the stator of motor are separated, and rotor turns round in the medium that is transferred, and its power is passed to rotor through stator field.
In addition, the manufacturing of canned motorpump is also uncomplicated, and its fluid end can design, make with relevant standard specification according to the structural type that centrifugal pump adopts usually.
The circular flow of canned motorpump is one of most important factor that guarantees the canned motorpump proper functioning, but the circular flow size of existing canned motorpump is difficult to again measure through concrete test method.
The model utility content
For solving the problems of the technologies described above, the purpose of the utility model is to provide a kind of measuring device of contrary circulation canned motorpump circular flow.
For achieving the above object, the technological scheme of the utility model is following:
A kind of contrary circulation canned motorpump circular flow measuring device comprises a canned motorpump, and the contrary loop exit end of said canned motorpump is provided with a flange; Said flange one end connects a flow measuring device, and said measuring device comprises two valves, a flowmeter and a pressure meter.
Preferably, said two valves are respectively first valve and second valve.
Preferably, said flowmeter is placed in the below of said first valve, and the use that matches.
Preferably, said second valve is placed in said manometric below, and the use that matches.
Through technique scheme, the beneficial effect of the utility model is:
The utility model is installed a flow measuring device on the flange of canned motorpump outlet end, this flow measuring device can accurately be measured the size of contrary circular flow.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiments of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the utility model structural representation.
The numeral corresponding part title represented among the figure with letter:
100. canned motorpump 101. flanges 200. first valves 300. second valves 400. flowmeters 500. pressure meters.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to shown in Figure 1, a kind of contrary circulation canned motorpump circular flow measuring device comprises a canned motorpump 100, and said canned motorpump 100 contrary loop exit ends are provided with a flange 101; Said flange 101 1 ends connect a flow measuring device, and said measuring device comprises two valves, a flowmeter 400 and a pressure meter 500.
Said two valves are respectively first valve 200 and second valve 300.
Its second valve 300 is placed in the below of pressure meter 500; Second valve 300 is used for pilot pressure meter 500 and can bear the size of pressure; When internal pressure surpasses tolerance range, can reduce internal pressure, thereby improve safety greatly through closing second valve 300.
The utility model is simple in structure, and is easy to use.
More than show and described basic principle of the utility model and the advantage of major character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
