Atmospheric pressure bottled water filling machine is filled under atmospheric pressure by the weight of the liquid. When the machine is in the “automatic” state, the machine will automatically carry out continuous filling at the set speed . And when the machine is in the “manual” state, the operator steps on the pedal to realize the bottled water filling machine. If the step is kept on, it will also become the state of automatic continuous filling. This type of filling machine is divided into two types: timing filling and quantitative filling, which are only suitable for filling low-viscosity and gas-free liquids such as milk and wine.
Working principle: A piston is driven by the cylinder to extract and discharge the material. The flow direction of the material is controlled by a check valve, and the stroke of the cylinder is controlled by a magnetic reed switch to adjust the filling volume. The filling machine generally adopts the flow meter filling method. Because of its unique characteristics, the lubricating oil has strict requirements on the filling machine and is relatively expensive. Therefore, the accuracy of the filling machine is relatively high, and generally requires To achieve an accuracy of 0.2%, lubricating oil filling machines are generally equipped with a temperature tracking system to maintain the stability of measurement accuracy.
