This relay is established on the pipeline of a high pressure of the entrance channel of a dehumidifier of a broad tank and carries out functions of the relay of low pressure and the relay of a high pressure.
Operation of the relay of low pressure
Operation of the relay of a high pressure
Pressure of a coolant is higher 32,2±0,2 than kg/cm2.
In this case pressure of a coolant becomes higher than counteraction of a spring And therefore the mechanical diaphragm is deformed and displaces to the right a pin.
At this moment dot contact (II) is disconnected, thereby there is a condition is SWITCHED OFF, and the magnetic coupling is closed, t, е, there is a condition is INCLUDED.
Pressure of a coolant is lower 2,0±0,2 than kg/cm2.
Thus pressure of a metal diaphragm becomes higher than pressure of a coolant therefore the diaphragm comes back to the initial form, dot contact (II) becomes isolated, and there is a condition is SWITCHED OFF.
