Description
Technical field
The present invention relates to liquid measure field, in particular to a kind of liquid level alarming switch detection method based on static liquid level
And its scaling method of alarming line.
Background technique
For the detection method of liquid level alarming switch, detection in the prior art is mainly by manually moving liquid level
Standard of the float of alarm switch as detection, and the scaling method of liquid level alarming switch alarming line, are first to open liquid level warning
The float of pass is put into liquid, using the sink-float degree of float as foundation, liquid level line is drawn on float, then by manually moving
The float of liquid level alarming switch measures the liquid of float using distance-measuring device (generally using ruler) to the position just alarmed
The distance between bit line and reference-calibrating face, the calibrating parameters as liquid level alarming switch alarming line.
Using detection method and its alarm of the float as liquid level alarming switch for manually moving liquid level alarming switch
The scaling method of line cannot intuitively embody float and float on situation on liquid level；And passes through and first draw liquid level line, then measure alarming line
Calibration mode, on the one hand increase the pilot process of calibration, measurement result is unreliable, on the other hand in manual mobile float
When, stability is poor in moving process, be easy deflection or imbalance, another further aspect due to liquid level alarming switch individual difference,
The sink-float degree of its float in a liquid is different to establish a capital equally, and various reasons are very big so as to cause measuring result error value.
Summary of the invention
The purpose of the present invention is being directed to the corresponding deficiency of the prior art, a kind of liquid level warning based on static liquid level is provided and is opened
The scaling method for closing detection method and its alarming line, can intuitively detect whether liquid level alarming switch can work normally,
And in the case where not needing control changes in liquid level, the present invention is capable of accurate scale liquid position alarm switch alarming line
Position, precision is high, easy to operate, quick, substantially increases the efficiency of detection, calibration.
The purpose of the present invention is what is realized using following proposal: a kind of liquid level alarming switch detection based on static liquid level
Method includes for driving the vertical of liquid level alarming switch vertical lifting to be detected using following liquid level alarming switch detection device
Lifting device and liquid storage container for storing liquid, the vertical lifting device are equipped with and open for installing liquid level warning to be detected
The mounting rack of pass and driving device for driving the mounting rack vertical lifting, liquid storage container are located at vertical lifting device
Below mounting rack, liquid level alarming switch to be detected is mounted on the mounting rack of vertical lifting device, and liquid level warning to be detected is opened
The float of pass is located in liquid storage container, and the liquid level alarming switch to be detected is connect with warning device, in liquid level alarming switch liter
(when open type liquid level in liquid level alarming switch lifting process while the conversion of liquid level alarming switch open and-shut mode during drop
While alarm switch is closed or while closed type liquid level alarming switch disconnects), the liquid level alarming switch to be detected is used for
It controls warning device and carries out warning note.The liquid level alarming switch to be detected can directly control warning device carry out alarm mention
Show, warning device can also be controlled by relay etc. and carry out warning note.Certainly, the liquid level alarming switch to be detected can be with
It is connect with control unit (such as single-chip microcontroller, PLC), warning device is controlled by control unit and carries out warning note.
Specific step is as follows: liquid level alarming switch to be detected is clamped on the mounting rack of vertical lifting device, and to be detected
The float of liquid level alarming switch is located in liquid storage container, loads onto quantitative liquid in liquid storage container first, make it is clamping to
The float of detection liquid level alarming switch floats in a liquid, and the liquid level alarming switch on mounting rack is then driven by driving device
It is risen or is dropped, so that the float of liquid level alarming switch be driven to be risen or dropped, and then detected liquid level alarming switch and whether can
It works normally, if in the entire lifting process of float (including flood float completely from liquid and divide completely to liquid with float
Process between and the process flooded float completely is kept completely separate to liquid from liquid and float), warning device is all
There is no alarm, then judge that liquid level alarming switch is faulty or damages.
A kind of scaling method of the liquid level alarming switch alarming line based on static liquid level uses following liquid level alarming switch
The caliberating device of alarming line, the caliberating device of liquid level alarming switch alarming line include for driving liquid level alarming switch to be detected perpendicular
The vertical lifting device of drop and the liquid storage container for storing liquid are gone straight up to, and for measuring liquid level alarming switch alarming line
The distance-measuring device of calibrating parameters.The vertical lifting device is equipped with the mounting rack for installing liquid level alarming switch to be detected
And the driving device for driving the mounting rack vertical lifting, liquid storage container are located under the mounting rack of vertical lifting device
Side.The distance-measuring device is mounted on mounting rack.The liquid storage container for being stored with liquid provides liquid level for liquid level alarming switch
Source, and the benchmark of water level is provided.Any one in the liquid level alarming switch to be detected and warning device, driving device or two
Kind connection, in liquid level alarming switch lifting process while liquid level alarming switch open and-shut mode is converted, the liquid level warning
Switch stops working for controlling driving device, and control liquid level alarming switch stops lifting, in liquid level alarming switch lifting process
In when liquid level alarming switch open and-shut mode conversion while, the liquid level alarming switch for control warning device carry out alarm mention
Show, stops working for prompting the state of liquid level alarming switch and operator being reminded to manually control driving device.It is described to be checked
