The barrel of the prefabricated pumping station is made of thickened mechanically wound GRP FRP material. One-time investment, low long-term operating cost, obvious energy-saving benefits, and in the case of demolition or occupied land, it can be hoisted up for secondary landfill reuse; Reliable quality, no leakage, no pollution to the environment; Light weight and low cost. The integrated prefabricated pumping station is upgraded and developed on the basis of the original variable frequency constant pressure water supply equipment and non-negative pressure water supply equipment, which is composed of stainless steel water tank, water pump, intelligent frequency conversion control cabinet, non-negative pressure device, pressurization device, water diversion device and pressure stabilizing tank, etc., which is a new type of mechatronics water supply equipment combined with computer technology, frequency conversion technology and motor pump, so as to meet the requirements of urban water supply pipe network, which does not produce negative pressure when pumping, and has a certain storage capacity, and continuously stops water during peak periods.
The equipment adopts microcomputer control inverter pump to operate at a constant number of revolutions, and the original pressure of tap water can be used to ensure that the pressure required by the user is constant. It has the advantages of energy saving, environmental protection, low noise and constant water supply pressure.
Prefabricated pumping station applications.
1. Applicable geographical scope: It is suitable for pressurized water supply in areas with sufficient pressure in the urban pipe network;
2. Applicable project types: large-scale intermediate pressurized pumping stations for production, domestic water and water supply plants of industrial and mining enterprises;
3. Applicable engineering parts: secondary pressurization system for water supply;
4. Other scope of application: domestic water for new construction, reconstruction, expansion of residential buildings, office buildings, hotels, restaurants and other public buildings;
5. Type of user: design unit, construction unit, supervision unit.
Principle. The equipment is linked with the fire control center, under normal conditions, through the control of the pressure stabilizer pump, the pressure required by the fire water supply network is maintained, and when the fire alarm occurs, it receives external signals such as the fire hydrant button and the fire control center, and automatically opens the fire main pump.
Construction time: Before the installation of the integrated prefabricated pumping station equipment, as long as the foundation pit is dug and the floor of the prefabricated pumping station is placed, the installation can be completed within 5-7 days. The traditional concrete pumping station is a steel concrete structure, and the bottom plate, pool wall and roof of the pumping station are constructed step by step, and the pouring and maintenance require 2-3 months of construction period. The accuracy of on-site construction is poor compared with that of product factory production.
Environmental pollution: The original sewage lifting pumping station is a traditional concrete pool, and the pre-buried pipeline is also a cement pipeline, and later it was found that the odor produced by the wastewater of the concrete pool volatilized into the air at will, which also polluted the atmosphere. The area of the concrete pool is also too large, and once the project is completed, it will be impossible to carry out landscaping treatment in a large area. The equipment is buried under the surface, and the above can be greened, and the environment is beautiful. The whole equipment generally does not need to be managed by a special person. The floor space can be reduced.
