The Control System Of Water Fountain
- Nov 01, 2017 -

Fountain control system, not only a wide range of water spray, but also the electromagnetic valve of the timing of the movement is very high. The traditional logic control of relays can not satisfy this requirement at all. In order to ensure the practicability and reliability of the system, the KDN-K3 series plc is used to control. Automatic cycle of the process for, eight minutes a cycle, a cycle of 12 times, each time, the solenoid valve action sequence is different, and then cycle. In the automatic cycle of each solenoid valve should be strictly according to their respective action sequence, reliable action.Water Fountain

In both processes, if each output point is controlled by a timer or counter, there is no doubt that the function required by the process can be realized, but the procedure will be more cumbersome. We analyzed the sequence diagram, the minimum time unit is 0.5 seconds, 49 solenoid valve to be in a time series datum according to the beforehand compiled pattern chart at different times opens or closes the stipulation solenoid valve, forms each kind of pattern the fountain. KDN-K3 System PLC function is powerful, the instruction is complete, we can use an accumulator to realize.Water Fountain

Fountain Experiment's basic principle is: the gas in the liquid solubility is very big, produces in the short time Enough pressure difference (negative pressure), then opens the piston, the barometric pressure will the beaker the liquid to press into the flask, forms the fountain in the tip conduit mouth. To solve this problem, we think of several factors that affect air pressure.Water Fountain

There are two ways to reduce the amount of matter in a gas: physical methods and chemical methods. Physical methods can take the gas away or physically dissolve, chemical methods can be chemically dissolved by chemical reaction or chemical, and the temperature of the gas can be lowered by pouring in cold water or by placing a wet towel at the bottom of the bottle, or by moving the device into a cooler environment, while increasing the volume of the gas can be taken to raise the temperature (e.g., A method of pouring or heating a towel on the bottom of a bottle or changing the volume of a container.Water Fountain
