Full-automatic non-negative pressure water supply equipment and water supply method

Abstract

The invention relates to full-automatic non-negative pressure water supply equipment and a water supply method. In the convention non-negative pressure water supply equipment, the problem that the water supply capacity is less than the water consumption of users is solved by the measures of the pressure maintaining and machine halt of pipe networks. The full-automatic non-negative pressure water supply equipment comprises a source pipeline (1) connected with a water source, wherein two pipelines between the source pipeline and a water supply pipeline (2) connected with the users are connected with a water pump (3) respectively; the water supply pipeline is connected with an outlet pressure detector (4); the outlet pressure detector is connected with a control device (5); the control device is connected with an inlet pressure detector (7) on a buffer tank (6); the buffer tank is connected with a pressure gauge (8); the water pump is driven by the control device; and the buffer tank is connected with the source pipeline through a pipeline (9) with a valve. The full-automatic non-negative pressure water supply equipment is used for the secondary pressurization of water supply pipelines.

Description

Technical field: [0001] The invention relates to a fully automatic non-negative pressure water supply equipment and a water supply method. Background technique: [0002] Non-negative pressure water supply equipment is a new type of water supply equipment developed in recent years. It has many advantages such as environmental protection, energy saving, sanitation, and economy. It is an updated product for urban and rural secondary pressurized water supply equipment. However, the non-negative pressure water supply equipment currently available on the market almost all have a common property: that is, when the water supply of the water supply network (Q 管网供水 ) is greater than the user’s water consumption (Q 用户用水 ), the water supply of the equipment (Q 设备供水 ) is equal to the user’s water consumption (Q 用户用水 ), when the water supply of the water supply network (Q 管网供水 ) is less than the user’s water consumption (Q 用户用 水 ), the water supply of the equipment (Q 设备供水 ) is equ...

Problems solved by technology

However, the existing non-negative pressure water supply equipment in this area is almost always taken measures to maintain the pressure of the pipe network, which is obviously unreasonable from the perspective of being responsible to users
