Embodiment Construction

[0016] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] like figure 1 As shown, the self-flowing differential pressure water supply system composed of two pools and a set of hydraulic flat weirs used in the present invention includes: high level pool (1), high level pool overflow well (2), low level pool (3), Low-level pool overflow well (4), high-level pool overflow weir (5), low-level pool flat weir (6), high-level pool remote liquid level gauge (7), remote flowmeter (8), remote differential pressure gauge (9), the remote liquid level gauge of the low-level pool (10), the hydraulic opening and closing device (11), and the water supply pipeline (12).

[0018] Depend on figure 1 It can be seen that the high-level pool (1) provided by the present invention is provided with a pool water inlet, an overflow drain, and a water outlet (such as nodes N01, N02, and N03 respectively), ...

Abstract

The invention belongs to the field of an industrial water supply system, and relates to a self flow pressure difference regulating water supply system. The self flow pressure difference regulating water supply system comprises a high-position water pool, a low-position water pool, a water supply pipeline and water use equipment, wherein the high-position water pool is sequentially connected with the water use equipment and the low-position water pool through the water supply pipeline; and a low-position water pool flat plate weir is arranged in the low-position water pool, so that a low-position water pool overflow well is formed in the low-position water pool. When the self flow pressure difference regulating water supply system is used, the flow rate under the work conditions of different pressure differences can be continuously provided for the water use equipment without the additional addition of pressure generating equipment (such as a water pump). Compared with a common use water pump variable-frequency water supply system, the self flow pressure difference regulating water supply system has the advantages that the flow rate regulation range is wide; the hydraulic control is simple; and the operation is stable.

Description

technical field [0001] The invention belongs to the field of industrial water supply systems, and in particular relates to a self-flowing pressure difference water supply system. Background technique [0002] In terms of nuclear engineering or industrial water use, water equipment needs to operate in a steady state or dynamically under different working conditions, and different working conditions require different pressure differences between the inlet and outlet of the water equipment, and the flow required for different working conditions Also different. In the prior art, the frequency conversion of water pumps is used to supply water. On the one hand, under the condition of low pressure difference, it cannot meet the low flow supply requirements of water equipment; It will cause water hammer in the water supply pipeline and affect the safety of water equipment operation. Contents of the invention [0003] The purpose of the present invention is to provide a self-flow...
