Embodiment 1

[0036] This embodiment provides a water supply method, such as figure 1 As shown, the method includes the following steps:

[0037] Step 110, control the first valve to open according to the received first opening signal, and flow the cooling water into the water pump.

[0038] In this step, when water supply and drainage are required, the first opening signal is first received, and the first valve is controlled to open according to the received first opening signal, and the self-use cooling water of the water pump flows into the water pump to cool and lubricate the bearings of the water pump. Wherein, the first valve is specifically a solenoid valve, and the water pump is a vertical shaft water pump.

[0039] Step 111, receiving a second opening signal, and controlling the second valve to open to a preset first angle range according to the second opening signal.

[0040] In this step, when it is determined that the flow rate of the cooling water reaches the preset flow rate...

Embodiment 2

[0052] Corresponding to Embodiment 1, this embodiment provides a water supply system, such as figure 2 As shown, the system includes: a first controller 1, a first valve 2, a flow meter 3, a second controller 4, a second valve 5, a third controller 6, a water pump 7, a fourth controller 8, a first Three valves 9 and pressure gauges 10; wherein,

[0053] When it is necessary to perform water supply and drainage, first, the first controller 1 receives the first opening signal, and controls the first valve 2 to open according to the received first opening signal, and the cooling water for the water pump flows into the water pump 7 for the water pump 7. Bearings are cooled and lubricated. Wherein, the first valve 2 is specifically a solenoid valve, and the water pump 7 is a vertical shaft water pump.

[0054] Secondly, when the system determines that the cooling water flow has reached the preset flow rate according to the flow meter 3, the second controller 4 is used to receive...

Abstract

The invention provides a water supply method and a water supply system. The method comprises the following steps: opening a first valve in accordance with a received first opening signal, and leading cooling water of a water pump to the water pump; when the flow rate of the cooling water reaches a preset flow rate, receiving a second opening signal, and opening a second valve to a preset first angle range in accordance with the second opening signal; receiving a third opening signal, and turning on the water pump within a first preset time range in accordance with the third opening signal; receiving a fourth opening signal, and opening the second valve to a second preset angle in accordance with the fourth opening signal; and when a water supply pipeline reaches a preset pressure range, receiving a first closing signal, and closing the first valve in accordance with a first closing signal. Therefore, the water supply method and the water supply system, in water supply and drainage works, can achieve remote automatic control over opening and closing of the water pump, so that the labor intensity and error operation risks of operators are reduced and water supply efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of water supply and drainage, and in particular relates to a water supply method and system. Background technique [0002] In the field of water supply and drainage, the water supply project is to supply residents, factories, mines and transportation enterprises with domestic and production water, fire-fighting water, road greening water, etc. It consists of water supply sources, water intake structures, raw water pipelines, water supply treatment plants and water supply pipe networks. Transport raw water to improve water quality. Drainage works exclude human domestic sewage and various waste water in production. [0003] In water supply and drainage projects, vertical axial flow pumps are usually used for water supply and drainage. The operating characteristics of the vertical axial flow pump are that the higher the head, the greater the pump power, the higher the corresponding motor current; therefore, i...
