The water supply network is divided into three categories according to the water source, system composition method and water transmission method. So please ask the respective characteristics of these three categories...

Vertical partition water supply mode. For buildings with a large number of floors, when the water pressure of the outdoor water supply network cannot meet the indoor water consumption, it can be divided vertically. Each area adopts different water supply methods: l) Direct water supply in low areas, and water supply methods for storage pools, pumps and water tanks in high areas.

Direct water supply method: When the water volume and water pressure of the outdoor water supply network can be satisfied at any time of the day. It is adopted when the water volume and water pressure of the indoor pipe network are required. The indoor water supply pipe system is directly connected to the outdoor water supply network, and the pressure of the outdoor pipe network is used to directly supply water to the indoor water supply system. This is the simplest and most economical way to supply water.

Give directlyWater method This method refers to the water supply method that directly guides the outdoor pipe network to each water point inside the building. It is suitable for the water supply network (municipal pipe network or community pipe network). The water volume and water pressure provided by the outdoor water supply network (municipal pipe network or community pipe network) can meet the internal water requirements of the building at any time, such as single-storey, multi-storey buildings and lower floors of high-rise buildings.

Building drainage system Building drainage system excludes sewage from residential buildings, public buildings and production buildings. The drainage system inside the building is generally composed of water receivers, drainage pipes, clearing facilities, ventilation pipes, sewage and wastewater lifting equipment and local treatment structures of sanitary ware or production equipment.

This water supply method is characterized by reliable water supply, simple system, investment-saving, simple installation and maintenance, which can make full use of the water pressure of the external network and save energy.However, there is no water storage equipment inside, and the water inside is cut off immediately when the external network stops.

There are three main types of water supply network systems: unified water supply network system, multi-water supply network system and water supply network system with different water transmission methods.

The construction goal of the urban underground pipe network information system isWhat

1. Integrate existing surveying and mapping materials to establish an urban spatial basic data platform, and build a spatial basic data sharing and exchange system; on the basis of the urban spatial basic data platform, carry out the construction of an urban construction information management system, and update and improve the urban planning and construction management system. Set the foundation. 1 System construction goals.

2. Objective The overall goal of the construction of the comprehensive underground pipeline information management system project in Zibo City is to improve the overall management level of urban construction, give full play to the role of underground pipeline archives in urban planning, construction, management, disaster prevention and reduction, and promote urban informatization and digital Zibo construction.

3. IV) Construction pipeline comprehensive management information system. Local pipeline industry authorities and pipeline units should establish and improve professional pipeline information systems on the basis of pipeline census.

The main differences between the operation diagram of the drainage pipe network system and the engineering drawing

The differences are as follows: the drainage pipe network system is usually divided into sewage pipe network system and the rainwater pipe network system, and the design content includes sewage and rainwater. A set of systems. Engineering drawings are the designer's graphical presentation of the design scheme, which is an important basis for construction and acceptance.

Does the pipeline plan match the pipeline system diagram, especially whether the pipeline direction, pipe diameter, height, plane positioning, etc. match. Whether the plane and system diagram of the pipeline coincide with the detailed sample diagram. Whether the pipe plane matches the pipe flow chart and system diagram.

There are many large engineering pipeline construction drawings, with the name of the home page, set upThe counting unit, the designer's certificate number, followed by the drawing catalog, and then the description, which also describes the requirements of the project.

Gas pipeline network remote wireless monitoring system

Overview Gas pipeline network remote monitoring system is a computer-based production process control and scheduling automation system for on-site monitoring and automated management. Remote monitoring mainly uses RTU as the terminal. At present, there are many forms, such as using PSTN, laying special line radio stations, etc.

The natural gas remote monitoring system is mainly composed of dispatch center, natural gas monitoring center, communication platform, natural gas remote measurement and control terminal, measurement (flowmeter, pressure sensor, etc.) equipment, ventilation equipment, etc.

Pressure isolation station: It is used for water supply enterprises to remotely monitor the water supply network. Staff can remotely monitor the pressure and flow of the city's water supply network at the water department dispatch center. Scientifically direct the start and stop of water supply equipment in various water plants to ensure the balance of water supply pressure and stable flow; timely detect and predict the occurrence of pipe burst accidents.

First, enter the IP of the router in the address bar of the browser to establish a connection. After logging in, set the LAN parameters and subnet mask, and the WAN login link. Then set the router to intranet address forwarding, which we usually use port 80. Then enter the domain name of Peanut Shell on the computer's software.

Is the power of the return water circulation pump of the heating pipe network system the same

The difference in the power size of the circulation pump. The high-power circulation pump is suitable for large-area living rooms and high-rise households. The larger the area of the house, the larger the heating area, and the greater the demand for heat; while the low-power circulation pump is suitable for smaller spaces and low-rise households.

The power of household heating circulation pump is generally about 100W. Circulation pump refers to the pump for conveying reaction, absorption, separation and absorption of channel fluid regeneration. There is a low water head, which is only used to overcome the pressure drop in the circulation system. A low-lift pump can be used. Circulating pump refers to action pump, and centrifugal pump refers to structural pump. The two are completely different concepts.

The power of household heating circulation pump is generally about 100W. Circulation pump refers to the circulating liquid pump that transports reaction, absorption, separation and absorption liquid regeneration in the device. It has a low lift, which is only used to overcome the pressure drop of the circulatory system.A low-lift pump can be used.
