Double constant pressure branch pipe supercharger and control method

Abstract

The invention relates to a double constant pressure branch pipe supercharger which comprises a plurality of water supply branch pipes connected with a municipal water supply main pipe network. The supercharger is characterized in that each water supply branch pipe is internally provided with a water pump in a built-in mounting manner; each water pump is independently provided with a control unit, so that each water supply branch pipe has an ability to adjust water pressure; and with the adoption of a control method provided by the invention, the water outlet pressure at the tail end of each water supply branch pipe is kept constant. The supercharger and the control method have the technical benefits that according to the double constant pressure branch pipe supercharger, running states of the water pumps can be controlled dynamically in real time according to the water pressure variation, the water outlet pressure of the water supply branch pipes is kept relatively constant, and a citizen can enjoy the quality water supply service.

Description

technical field [0001] The invention relates to a constant pressure water supply technology, in particular to a double constant pressure branch pipe supercharger and a control method. Background technique [0002] The urban water supply system is generally composed of the main municipal water supply network and the water supply branch pipes connected to the main municipal water supply network. The water supply branch pipes transport the water from the main municipal water supply network to each water point. The pressure has an important impact; with the continuous expansion of the urban area, the water supply pressure of the municipal water supply main network fluctuates, and its specific manifestations are as follows: [0003] 1. During the peak of water consumption, the main municipal water supply network is not connected to the peak of water consumption, and there will be a serious shortage of water pressure. 2. Due to the limitation of the geographical environment, ...

AI Technical Summary

Problems solved by technology

[0003] 1. During the peak of water consumption, the main municipal water supply network is not connected to the peak of water consumption, and there will be a serious shortage of water pressure.

2. Due to the limitation of the geographical environment, the main municipal water supply network has a serious shortage of water pressure in places with relatively high geographical locations

3. The equipment for pressurizing the main municipal water supply network can only pressurize the main main network from the source. This method of pressurization is difficult to effectively control the water pressure at the end of the main municipal water supply network and the water supply branch pipes

4. Due to the inherent pipe damage of the main municipal water supply network, the water pressure will also be insufficient

5. The existing pressurization equipment will affect the normal water supply of the municipal water supply main network, and even cause negative pressure on the municipal water supply main network
