Manufacturer of constant pressure variable frequency water supply equipmentcharacteristic

It consists of three parts: a "rectifier" that converts power frequency into DC power, a "smoothing circuit" that absorbs voltage pulsations generated by converters and inverters, and an "inverter" that converts DC power into AC power. Current type is a frequency converter that converts the DC of a current source into AC, and its DC circuit filter is an inductor. The main circuit of the non negative pressure water supply frequency converter is the power conversion part that provides voltage and frequency regulation power to the asynchronous motor. The main circuit of the frequency converter can be roughly divided into two categories: voltage type is a frequency converter that converts the DC of the voltage source into AC, and the filtering of the DC circuit is a capacitor.

advantage

1. Convenient management: The equipment runs fully automatically and has functions such as overload, short circuit, overcurrent, water shortage, and automatic reset.

2. Stable water pressure: Real time detection of outlet pressure through sensors, using frequency conversion control to ensure constant outlet pressure

3. Low investment: No need to build water pools and tanks, no need for frequent cleaning and disinfection, saving more than 50% of construction costs and later cleaning and maintenance costs.
