Secondary water supply frequency conversion unit
Secondary water supply frequency conversion unit, widely used in various fields such as water conservancy, construction, fire protection, electric power, environmental protection, petroleum, chemical industry, etc.
Constant pressure variable frequency water supply equipment, composed of anti-fouling partition unit, variable frequency pressurizing unit, pressure compensation unit, pressure transmitter, microcomputer control unit and pipeline system, etc., and through the variable frequency water pump under the conditions permitted by the municipal water supply network A device that can automatically and continuously supply water to the water supply network during operating or non-operating hours.
The variable frequency constant pressure water supply unit and the water supply equipment pump have a good sealing structure: the friction pair of the mechanical seal adopts graphite to tungsten carbide, which does not leak water and has a long service life. The pump body of the water supply equipment can be cast with cast iron, ductile iron, carbon steel, alloy steel, stainless steel and other materials, and can be customized and produced according to the special needs of users. The frequency conversion constant pressure water supply system is widely used in various fields such as water conservancy, construction, fire protection, electric power, environmental protection, petroleum, chemical industry and so on.
The variable frequency constant pressure water supply equipment is a water supply method in which water pumps are superimposed on the water pressure of the municipal water supply pipe network, and water is directly taken from the municipal water supply pipe network.
Frequency conversion constant pressure water supply equipment According to the form of municipal pipe network, year-round water pressure, water cut-off conditions, and user requirements for water quality and water supply guarantee rate, the suction pipe of frequency conversion constant pressure water supply equipment should be independently connected to the outdoor municipal pipe network. When it is a ring network, it should be connected from the ring network. The pipe diameter of the municipal water supply pipe network should not be less than the standard, and it should not be less than 50mm. Municipal water supply pipe network pipe diameter water supply equipment suction pipe 100 ≤40 150 ≤50 200 ≤80 300 ≤100
5.1.6 The diameter of the suction pipe of the water pump should be two or more levels smaller than that of the municipal water supply pipe network, or no more than 1/3 of the pipe diameter of the municipal water supply pipe network.
Features:
The frequency conversion constant pressure water supply equipment avoids the frequent start of the water pump, which is highly efficient and energy-saving, with low noise.
Application scope:
1. Domestic water supply for newly built residential quarters, villas, office buildings and complex buildings.
2. Domestic water supply for high-rise buildings, firefighting water, high-end hotels, restaurants, etc.
3. Renovation of traditional water supply systems such as air pressure water supply and ground pool pressurization.
4. Various boiler cold water supply systems and boiler hot water.
5. The intermediate pressurization pump station of the water plant and the secondary pressurization of the tap water.
6. Stabilize the production, domestic water and pipe network of various industrial and mining enterprises.
7. Various types of circulating water and cooling water supply systems.
8. The pressure of tap water cannot meet the requirements of life, fire-fighting pressurized water supply, etc.
