The concrete practice of liquid level centralized automatic control

Situation analysis In real estate residential community development projects, there are often water supply problems. First, there are many pump rooms and large floor space. The second is that it is not convenient for future property management. Third, it is time-consuming, labor-intensive, time-consuming, expense-consuming and time-consuming. Fourth, waste of water resources.

A ten-story high-rise residential community often uses ten household water supply pump rooms, and each living pump room needs two domestic water pumps. A total of ten pump rooms, twenty pumps, and ten life pump control boxes are used. Ten dual power supply control boxes. A pump room needs to use an area of ​​20 square meters, a total area of ​​20,000 square meters.

Shanghai Su Mao Automation Equipment Co., Ltd. has accumulated decades of experience and developed and developed new products for the new century. High-level centralized water supply for real estate residential quarters (automatic control of water supply for liquid level display), multiple roof tanks, and one water pump to supply water to multiple roof tanks. The area of ​​the water pump room is only 50 square meters, so that the pump room can save an area of ​​10 square meters. Only two sets of water pumps are used to save 18 pumps. As long as the life pump control box is used, it saves nine units. As long as one dual power control box, save nine.

From the analysis of the above data, we know that it saves a lot of resources, a lot of costs, a lot of manpower, a lot of time, convenient for property management, from the original 10 inspections, reduced to just one inspection. The equipment is composed of JZK06 series centralized level automatic display control water supply complete device consists of liquid level sensor, display control instrument, centralized control box, logic circuit, living water pump control box, living water pump and float ball valve. With open pump, stop pump position setting and adjustment, the tank water level can be controlled within a certain range. Visually display the water level of each tank, and output the high and low alarm contacts.

Working principle When the water level in any water tank on the roof reaches the lower limit, a low water level signal is sent from the water tank level sensor and sent to the display control instrument. The display control instrument control mechanism controls the secondary control loop of the living water pump control box, and the power is turned on. The water pump starts to run and supply water to the roof tank. When the water level of the first tank reaches the upper limit, a high water level signal is sent from the tank sensor and sent to the display control instrument. The control instrument control mechanism is shown to close the tank control circuit. At this time, the water tank enters The water is closed by the float valve and the tank is stopped from entering the water. Equivalent to the tank out of the control system and water supply system. When the water level of the second tank reaches the upper limit, a high water level signal is sent from the tank sensor and sent to the display control instrument. The control instrument control mechanism is shown to close the tank control circuit. At this time, the water inflow of the tank is closed and stopped by the float valve. The water tank enters the water. Equivalent to the tank out of the control system and water supply system. By analogy, when the last tank reaches a high water level, the liquid level sensor sends a high water level signal and sends it to the display control instrument. The display control instrument control mechanism controls the secondary circuit of the living water pump control box, shuts down the power supply, and stops the domestic water pump.

The above process is repeated for a round trip to realize automatic water supply in the community.

The above is the specific practice of our centralized water supply in residential quarters, hoping to bring convenience to everyone.
