Description

The online flow detector of a kind of high accuracy

Technical field

This utility model belongs to lubricating utensil technical field, relates to the online flow detector of a kind of high accuracy.

Background technology

Along with the development of industrial technology, increasing equipment is come out one after another, and the most a lot of middle and high speed rotate Bearing is more and more higher to the quantitative requirement of the flow of lubricating oil, temperature and pressure, for accurate quantification, level pressure, fixed Gentle cunning, many main frame producers and lubricating utensil manufacturer widely used effusion meter measuring equipment, current flux meter city The effusion meter kind commonly used on field is divided into: float-type flowmeter, baffle-type effusion meter, screw effusion meter etc., The use of various effusion meters all has certain limitation, such as: float-type flowmeter must be situated between according to measuring when selecting Matter and temperature (as different in oil viscosity at different temperatures) are demarcated, and can be only achieved permissible accuracy.

The float-type flowmeter used in the market all can only measure the flow of single oil product, simultaneously medium reality temperature The certainty of measurement of such effusion meter is affected the biggest by the change of degree, it is difficult to accomplish accurately to control.Exist when effusion meter simultaneously When going wrong after long-play, owing to not having built-in bypath valve, scene is overhauled when can only wait shutdown again, Cannot accomplish that online maintenance is changed, bring certain difficulty to on-the-spot maintenance.Particularly papermaking equipment, produces Line length, oil site is many, need the most integrated multiple effusion meters in a flow rate disc, except float-type flowmeter has Outward, the design of other general effusion meter mostly is single-point profit to integrated multi point lubricating function (but low precision) together Sliding design, when requiring to provide multiple oil site to use, the same quantity effusion meter that can only correspondence be counted is integrated in one Rise, cause equipment profile excessive, cause certain difficulty to the over all Integration of relevant device.

The convenience of partial discharge meter producer precision Yu use in order to improve effusion meter, respectively from reducing profile, increasing Add the aspect such as external bypass valve, increase external display screen to improve, but overcome existing the most completely The obvious drawback of effusion meter, is not truly realized: the monitoring the most simultaneously of low-profile, modularized design, this locality, On-bne repair etc..

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of modularized design, compact conformation, Can every some flow of on-the-spot regulation in real time, can the online flow detector of high accuracy of on-bne repair.

The technical solution of the utility model is as follows:

The online flow detector of a kind of high accuracy, it includes effusion meter, signalling component, flow control valve and two Cross valve；At flowmeter shell built with upper and lower two pitch wheels；In flowmeter shell, gear A tooth on be inlaid with Magnet；On flowmeter shell, the surface of corresponding gear is provided with signalling component；? The porch of effusion meter is provided with flow control valve and two position four-way valves, the entrance of two position four-way valves and flow control valve Outlet connects, and the outlet of two position four-way valves is connected with the outlet of effusion meter, and two other interface of two position four-way valves divides It is not connected with the entrance and exit of effusion meter.

Further, described signalling component is proximity switch；Proximity switch refers to when switch is close to jobbie, I.e. send the switch of control signal.

Further, described signalling component band LED display.

Further, described signalling component (proximity switch) is electrically connected with external transducer.

The beneficial effects of the utility model:

Online flow detector of the present utility model, employing modularized design, compact conformation, can be according to difference Field condition is by integrated for multiple effusion meters, and measurement result is not affected by dielectric viscosity, the accurate range of measured value Extensively, every some flow can on-the-spot regulate in real time, can change signalling component with on-line cleaning, and flow loss is little；Sender Element band LED shows, more intuitive and convenient.

Detailed description of the invention

Below in conjunction with drawings and Examples, this utility model is further described.

Embodiment

As it is shown in figure 1, the online flow detector of this utility model one high accuracy, it includes effusion meter A, sends out News element, flow control valve D and two position four-way valve B；Flowmeter shell built with upper and lower two intermeshing Gear Z；In flowmeter shell, a tooth of gear is inlaid with Magnet；(housing on flowmeter shell Outside), the surface of corresponding gear is provided with signalling component proximity switch S, proximity switch and external transducer Electrical connection；Flow control valve D and two position four-way valve B it is provided with in the porch of effusion meter, two position four-way valve B's Entrance is connected with the outlet of flow control valve D, and the outlet of two position four-way valve B is connected with the outlet of effusion meter, two Two other interface of cross valve B is connected with the entrance and exit of effusion meter respectively.

Described effusion meter is a kind of gear type volumetric flowmeter；The traffic monitoring of gear type volumetric flowmeter is former Reason is: when pumped medium flows through effusion meter, flowmeter shell and gear pair (two gears being meshed, quite Then two rotors) the interior pressure that formed of front side cavity, so far produce pressure reduction before and after gear pair, under the effect of pressure reduction Gear rotates.When the flow increases, before and after gear pair, pressure reduction also increases, and gear rotational speed increases；When flow subtracts Time few, pressure reduction diminishes, and gear rotational speed is the most slack-off.It is definite value owing to gear pair revolves the amount of the institute's pumped (conveying) medium that turns around, institute With, as long as we measure the number of turns that a gear rotates in certain period of time, just can converse in the unit interval Flow through the flow of effusion meter.

The flow monitoring operation principle of the online flow detector of high accuracy of the present utility model is: fluid (lubricating oil) Entered in effusion meter A housing by flow control valve D, drive two gears being meshed to rotate, when on gear Being inlaid with the tooth spiral of Magnet when forwarding near proximity switch S, proximity switch S is just triggered once, proximity switch S Be equivalent to a signalling generator (signalling component), after signalling generator (proximity switch S) detects the rotational frequency of rotor, Real-time traffic signal is converted to according to the frequency signal rotated by external transducer；Each online flow detector Porch be provided with flow control valve D and two position four-way valve B (bypass valve), the flow of every can be by this point The built-in flow control valve D of flow detector individually sets, meanwhile, for the ease of scene cleaning and more gear changing Z (rotor), is additionally provided with bypass valve that is two position four-way valve B, it is possible to achieve do not shut down in the flow detector of every Line is changed.

This utility model is the volume principle design according to gear pump, and the rotation of gear is dependent on pumping fluid media (medium) Pressure provides power, and this device utilizes three-dimensional software dynamic analog, and information processing system integrated moduleization designs, There is monitoring, on the spot Flow-rate adjustment and editor's function such as setup parameter and warning in real time, and can remotely control, it is achieved Optimized design.
