Description

ZSW series microcomputer controlled constant pressure water supply equipment of power frequency pump is a new intelligent water supply equipment. It applies advanced automatic control technology to intelligently control the constant pressure variable automatic water supply of power frequency pump; Or equipped with full-automatic water supply equipment with compound control of frequency conversion high-speed stabilized pressure pump; After cooperating with the diesel pump set, it can automatically complete the fire water supply unattended in case of normal power supply failure. When the frequency conversion speed regulation is not used for fire control, the microcomputer is used for intelligent control according to the fire control requirements. It is suitable for various types of water supply (including fire control) to improve the reliability of water supply. It solves the problem of power frequency overpressure of water supply pump; Dead pump; And other problems, with a wider range of applications.

Due to the use of PLC (or PC), the intellectualization is realized according to the fire protection requirements, the reliability is improved, and the cost can be greatly reduced. It is an ideal new type of water supply equipment with high quality, low price and reliability.

In addition to the intelligent control of high-speed pressure stabilizing pump, it also solves the problem of automatic control of water supply network.

In the system with diesel pump set, it can completely achieve unattended fire water supply without grid power supply, especially suitable for fire water supply of petroleum enterprises.
