During the flood season, as the water level in the reservoir rises to a certain height, the vacuum system automatically activates. With the air in the flushing chamber gradually being evacuated by the vacuum system, a negative pressure state is formed, maintaining a constant storage state for the water level and volume in the flushing chamber.
The Myuan-VFS vacuum flushing system, with the assistance of a vacuum system and a group of control valves, can absorb an adequate amount of water and maintain it at a certain height. This generates sufficient potential energy. After the pool is emptied, the water in the treated water room is released, converting the water's potential energy into kinetic energy, creating a powerful flushing water flow. This flow carries the residual sediment in the pool to the collection pit and discharges it to the wastewater treatment plant.
Vacuum Negative Pressure System
Power unit of a vacuum flushing system unit, this system consists of a complete set of equipment including a single-stage scroll vacuum pump, vacuum valves, vacuum gauges, intelligent control cabinet, vacuum tank, and corresponding pipeline valves. It can be started and stopped manually or automatically. Optional single-pump/dual-pump alternating operation mode.
Features:
◆ No underwater facilities or parts; maintenance is accessed within the regulating pond.
◆Supply of extra water, utilizing stored rainwater (or mixed wastewater) for flushing.
◆High cleaning efficiency (up to 7 meters of water head).
◆ Even in long or gently sloping channels, it offers superior flushing effects.
Features:
◆Even with light rainfall, it can still function as a flushing agent.
◆Available for external water supply for flushing as needed.
The system's use is not restricted to the geometric shape of the water storage room.
Low energy consumption.
◆Automated operation; the system can also be upgraded for remote control.
The pool contains no equipment requiring maintenance, offering a superior work health and environment.
Minimal maintenance (simply requires regular oil changes).
Automatic Diaphragm Valve
Made of SUS304, it includes a large EDPM diaphragm valve, vacuum retention device, and vacuum break device. It is a component of the entire vacuum flushing system, connected to the vacuum negative pressure system via vacuum tubes and air supply pipes.
