1. The utility model provides a medicine pump control system, is formed by the pipeline with feed valve, medicine pump, material loading valve connect gradually, its characterized in that be equipped with pressure sensor on the pipeline between medicine pump and the material loading valve, pressure sensor links to each other with the pilot lamp.

2. The drug pump control system of claim 1, wherein there are two indicator lights corresponding to normal pressure and abnormal pressure conditions, respectively.

3. The drug pump control system of claim 1 or 2, wherein the pressure sensor is further coupled to a speaker.

Technical Field

The invention relates to a drug pump control system.

Background

Some medicine pumps draw corrosive solution, so the position of a control box must be far away from the pump and a valve, and the defect is that a pump opening operator cannot confirm the opening condition of a feeding valve at any time, so the medicine pump is usually idle, pump accessories are damaged, and even liquid medicine is leaked.

Disclosure of Invention

The invention aims to provide a medicine pump control system which can effectively reduce the idling condition of a medicine pump.

The drug pump control system is formed by sequentially connecting a feeding valve, a drug pump and a feeding valve through a pipeline, and is characterized in that a pressure sensor is arranged on the pipeline between the drug pump and the feeding valve and is connected with an indicator lamp.

The original medicine pump pipeline is only provided with two manual switches of a feeding valve and a feeding valve, and a feedback element is not arranged. The invention sets up the pressure sensor on the pipeline between feed valve and the medicine pump, when the medicine pump is idling, the pipeline between feed valve and the medicine pump is no liquid medicine to pass through, the pressure of the pressure sensor is lower than the predetermined value at this moment; when the medicine pump does not idle, the pipeline between the medicine pump and the feeding valve is provided with liquid medicine, the pressure of the pressure sensor is higher than a preset value, the corresponding pressure condition of the pressure sensor can be displayed through the indicating lamp, so that an operator can conveniently know whether the medicine pump idles or not, and timely take corresponding measures when the medicine pump idles.

Furthermore, the number of the indicator lamps is two, and the indicator lamps respectively correspond to the normal pressure condition and the abnormal pressure condition, so that an operator can conveniently distinguish whether the medicine pump idles.

Further, the pressure sensor is also connected with a loudspeaker, and when the medicine pump idles, the alarm is also sent through the loudspeaker, so that an operator at a remote place can know the idling condition of the medicine pump.

The medicine pump control system of the invention feeds back the liquid medicine condition in the pipeline through the pressure sensor, thereby reflecting whether the medicine pump idles or not, reminding an operator through the indicating lamp, being beneficial to avoiding the idling problem of the medicine pump and further prolonging the service life of the medicine pump.
