Application of pressure transmitter in secondary water supply industry

The constant pressure water supply pump station uses multiple pumps and motors, which can be put into operation according to the water consumption. Therefore, the power of a single pump motor is not large, and the system has a backup pump for maintenance without stopping work. The running number of the water pump is controlled by PLC, and the motor speed is controlled by the frequency converter to meet the needs of different water consumption.

The pressure sensor is one of the main accessories in non-negative pressure water supply equipment and variable frequency constant pressure water supply equipment. The original remote pressure gauge is upgraded to a pressure sensor. The previous remote pressure gauge not only makes the entire water supply system unstable, but also It also needs to be replaced frequently, which increases the cost of after-sales service. The use of pressure sensors can not only solve the problem of unstable water supply, but also is not easy to damage. At the same time, it also reduces after-sales costs.

Through the high-sensitivity pressure switch or pressure sensor installed on the water supply pipe network, the pressure change of the water supply pipe network when the water consumption changes is detected, and the changing signal is continuously transmitted to the microcomputer. According to different operating conditions, the compensation amount is dynamically controlled to achieve dynamic pressure balance and ensure a constant pressure in the water supply pipe network to meet the water needs of users.

In fact, the pressure sensor can be divided into: pressure sensor and pressure transmitter according to the output signal and whether the amplifier circuit is installed in the body. At the same time, according to whether it can measure corrosive media and adapt to harsh environments, it can be divided into: general-purpose and isolated. According to the different signals, it can be divided into current-type pressure sensors: generally 4-20mA; and voltage signal-type pressure sensors. : 0 to 12V.
