The pressure tank is used in the closed water circulation system to balance the water volume and pressure, avoid frequent opening of the safety valve and frequently replenishment of the automatic replenishment valve. The expansion tank plays the role of accommodating the expansion water, and can also function as a replenishing tank. The expansion tank is filled with nitrogen, and a large volume can be obtained to accommodate the amount of expansion water. The high and low pressure expansion tanks can use their own pressure and are connected to the regulated system. Make up water. All the control points of the device are interlocking reactions, automatic operation, small pressure fluctuation range, safety, reliability, energy saving, and good economic effect.
No need to build a water tower, small investment, small footprint, the use of water and gas automatic adjustment, automatic operation, energy and tap water automatically connected to the grid, after the power is still available for water, after a few years without supervision. Compared with the construction of a water tower, it saves 70% of investment, and saves 60% of investment compared to a high-level water tank, which greatly saves civil engineering investment.
Widely used in enterprises, institutions, residential areas and rural areas of production, living, office water. Water users are in 20-2000 households. The daily water supply is 20-50000m3, and the water supply height is 150 meters, which is a 50-storey building.
The operation management of pressure tank pipe network has important practical significance for guaranteeing service quality, extending pipe network life, reducing operating costs, and reducing leakage.
The contents of pipe network management mainly include:
(1) Pressure tank pipe network information data management.
(2) Monitoring and simulation of pressure tank network operation.
(3) Pressure tank network optimization scheduling.
(4) Leak detection and browning of pressure tanks.
(5) Pressure tank pipeline anti-corrosion and descaling.
