Tank is connected.
It is micro-corrosion liquid in the pump A as present invention further optimization.
It is OSP liquid medicine in the pump B as present invention further optimization.
As present invention further optimization, the gear is connected with the output shaft of motor.
A kind of application method of OSP liquid medicine added automatically system, it the following steps are included:
Step 1: motor operating with moving gear after powering on at the uniform velocity operate；
Step 2: when needing to match micro-corrosion liquid in medicinal cupping and OSP liquid medicine with the ratio of 1:5, by central processing
Device sends the signal for matching data on counter,
Step 3: the signal for opening sensor is sent to sensor by counter, sensor receives gear and turns over 1
After the signal of tooth, sensor closes and the signal of a tooth is sent on counter, is sent the signal of a tooth by counter
To timer；
Step 4: after timer receives signal, control pump A is opened, the time that pump A6 is opened be gear turn over 1 tooth when
Between, pump A injects micro-corrosion liquid to medicinal cupping；
Step 5: when pump A close after, pump A stop to medicinal cupping inject micro-corrosion liquid meter, when device will pump A close signal send
To counter, the signal for opening sensor is sent to sensor by counter, and sensor receives after gear turns over 5 teeth, is passed
Sensor, which is closed, to be received signal and the signal of 5 teeth is sent on counter, and the signal of 5 teeth is sent to timing by counter
Device；
Step 6: after timer receives signal, control pump A is opened, the time that pump A is opened be gear turn over 5 teeth when
Between, pump B7 injects OSP liquid medicine to medicinal cupping.
As present invention further optimization, in step 2 Chinese medicinal pot the ratio of micro-corrosion liquid and OSP liquid medicine as needed into
Row adjustment.
As present invention further optimization, the quantity of the sensor and counter is at least one.
The utility model has the advantages that a kind of OSP liquid medicine added automatically system provided by the invention and its application, compared with prior art,
It has the advantage that
(1): promoting the stability of product quality；
(2): reducing liquid medicine waste, save production cost；
