Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.The present embodiment is with the utility model
Implemented premised on technical solution, the detailed implementation method and specific operation process are given, but the guarantor of the utility model
Shield range is not limited to the following embodiments.
A kind of low hydraulic pressure warning device of networking for water cooling air conditioning system, as shown in Figure 1, including sequentially connected water
Pressure sensor 1, analog to digital conversion circuit 2, controller 3 and wireless receiver 4 and shell 5, analog to digital conversion circuit 2, control
Device 3 and wireless receiver 4 are set in shell 5, and analog to digital conversion circuit 2, controller 3 and wireless receiver 4 are set to
It is connect in pipeline and by being routed through shell 5 with analog to digital conversion circuit 2.By configuring hydraulic pressure sensor 1, analog-to-digital conversion electricity
Road 2, controller 3 and wireless receiver 4 may be implemented to be monitored the hydraulic pressure in water cooling air conditioning system pipeline, from
And low hydraulic pressure alarm may be implemented, improve refrigeration effect.
As shown in Fig. 2, shell 5 is equipped with the anchor ear 51 for being connected on the outside of pipeline, convenient for the installation of single unit system.
As shown in Figure 3 and Figure 4, hydraulic pressure sensor 1 includes: sensor shell 11；Slider 12 is set in sensor shell 11,
And the elastic packing between 11 inside of sensor shell；Conducting spring 13, side are connect with slider 12, and the other side is connected to pressure
Quick resistance 14；Varistor 14 connects with divider resistance 15 and power supply 16 and forms closed circuit, and formed with divider resistance 15
