Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.
As shown in fig. 1-2, a pump station water pressure warning device is characterized in that: comprises a box body 1 and a signal receiving antenna 10 arranged in a pump room, the top of the box body 1 is provided with a signal transmitting antenna 2, the signal transmitting antenna 2 is connected with a control module A3 arranged in the box body 1 through a lead signal, the control module A3 is a ZKD-8I8RO-LORA wireless io module produced by Shenzhen, national comprehensive intelligent control science and technology development Limited company, the control module A3 is connected with a frequency converter 9 (MOTOR POWER 460Vac/3 phi) through a lead signal, a main pipeline 4 used for conveying is arranged inside the box body 1, one side of the main pipeline 4 is provided with a branch pipeline A5, the branch pipeline A5 is communicated with a liquid inlet of a first pump body 6, the first pump body 6 is specifically a booster pump, a liquid outlet of the first pump body 6 is communicated with a pressure stabilizing tank 7 (AQUACH 5L), the pressure stabilizing tank 7 is communicated with a branch pipeline B8, the branch pipeline B8 is communicated with the main pipeline 4, a pressure controller (PPTRANSTTER 4. PUST 4. 0104. P) is arranged at a tank opening of the pressure stabilizing tank 7, the pressure controller is in signal connection with the frequency converter 9 through a lead, when the pressure of a pressure gauge on the pressure stabilizing tank 7 is abnormal, the control module A3 transmits a signal to the signal receiving antenna 10 through the signal transmitting antenna 2, the signal receiving antenna 10 controls the second pump body 11 to be opened and operated after receiving the signal, the signal receiving antenna 10 is connected with the control module B through a lead, and the control module B controls the second pump body 11 to be opened or closed.
