Water pressure switch is not too low pressure on the power is too high to power it?
Answer: According to the normal logic of thinking, is the design of the control circuit.
Method: use the electrical contact pressure gauge to detect the pipeline water pressure, when the water pressure is less than the set value, the electrical contact conduction; when the water pressure is greater than the set value, the electrical contact is broken. Control the operation and stop of the pump with electric contacts.
Note: When the pump power is large, to use the electrical contact control relay on and off, in the use of relay control pump operation and stop. To prevent electrical contact burning.
The pressure switch is a simple pressure control device, when the measured pressure reaches the rated value, the pressure switch can issue an alarm or control signal. The general principle of the pressure switch is that when the pressure inside the system is higher or lower than the rated safety pressure, the sensor inner diaphragm moves instantaneously, pushing the switch connector through the connecting rod to turn on or off when the pressure drops to When the rated pressure is exceeded, the diaphragm is automatically reset, or the switch is automatically reset, or simply when the measured pressure exceeds the rated value, the free end of the elastic element is displaced, directly or after comparison, pushing the switching element, changing the switching element Of the state, to achieve the purpose of controlling the measured pressure. The pressure switch uses elastic elements such as single-ring spring tube, diaphragm, diaphragm and bellows. Switch components are magnetic switch, mercury switch, micro switch and so on. The following are the same as the "
When the pump power is large, to use the electrical contact control relay on and off, in the use of relay control pump operation and stop. To prevent electrical contact burning.
Water pressure switch is not too low on the power is too high to power is so designed. Use the electrical contact pressure gauge to detect the pipeline water pressure, when the water pressure is less than the set value, the electrical contact conduction; when the water pressure is greater than the set value, the electrical contact is broken. Control the operation and stop of the pump with electric contacts.
