Problems solved by technology
[0002] At present, the large and small pumps of the pressurized water supply system on the market are combined with frequency conversion and constant pressure water supply devices. Generally, the small pump is converted to frequency, and the large pump is soft-started to switch to power frequency operation. Phenomena such as ultra-high pressure and low-frequency operation of small pumps or frequent start and stop of large pumps affect normal water supply

A greening water-supply frequency conversion device comprises a rectangular support, a pressure stabilizing tank and three water supply pumps which are sequentially distributed on the support from left to right, a water supply pipeline is arranged at the bottom of the pressure stabilizing tank, three branch pipes are arranged on the water supply pipeline to be connected with the three water supply pumps respectively, a sluice valve and a ball valve are arranged on each branch pipe, the water supply pipeline is provided with a sluice valve and an electric contact pressure meter, the side wall of the pressure stabilizing tank is provided with a pressure release opening, and a safety valve is arranged at the top end of the pressure stabilizing tank. A frequency conversion soft starting mode is adopted, equipment operation is balanced, a large current impact is avoided, and the service life of equipment is prolonged; the equipment is compact in structure, small in occupied area and fast to install, the investment is saved, and secondary pollution is avoided.
Description
technical field [0001] The invention relates to the field of environmental protection water supply, in particular to a water supply frequency conversion device for greening. Background technique [0002] At present, the large and small pumps of the pressurized water supply system on the market are combined with frequency conversion and constant pressure water supply devices. Generally, the small pump is converted to frequency, and the large pump is soft-started to switch to power frequency operation. Phenomena such as ultra-high pressure and low-frequency operation of small pumps or frequent start and stop of large pumps affect normal water supply. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a product with compact structure and complete functions, which replaces traditional water supply devices such as water towers and high-level water tanks, saves engineering investment, shortens the engineering period, av...
