Non negative pressure variable frequency water supply equipment Manufacturer of non negative pressure water supply equipment Variable frequency domestic water supply equipment

Description :

Non negative pressure variable frequency water supply equipmentPut into use, the water from the tap water pipeline enters the steady flow tank, and the air inside the tank is discharged from the vacuum eliminator. After the water is filled, the vacuum eliminator automatically shuts off. When the pressure of the tap water network can meet the water requirements, the system supplies water directly to the water network through a bypass check valve; When the pressure of the tap water network cannot meet the water requirements, the system pressure signal is fed back to the variable frequency controller through a remote pressure gauge. The water pump runs and automatically adjusts the speed and constant pressure water supply according to the amount of water used. If the running water pump reaches the power frequency speed, another water pump will start variable frequency operation. When the water pump is supplying water, if the water volume in the tap water network is greater than the flow rate of the water pump, the system maintains normal water supply: during peak water usage, if the water volume in the tap water network is less than the flow rate of the small pump, the water in the stabilizing tank can still supply water normally as a supplementary water source. At this time, air enters the stabilizing tank through a vacuum eliminator, and the vacuum inside the tank is destroyed, ensuring that the tap water network does not generate negative pressure. After the peak water usage, the system returns to normal water supply. When the water supply network is shut down, causing the liquid level in the stabilizing tank to continuously decrease, the liquid level detector will feedback the signal to the variable frequency controller, and the water pump will automatically stop to protect the water pump unit. When there is a low flow of water supply at night and the pressure of the tap water network cannot meet the requirements, the pressure tank can store and release energy, avoiding frequent starting of the water pump.

Non negative pressure variable frequency water supply equipmentThe Seven Major Advantages

　　1. Pollution free: There are no pools or water containers, and the incoming water operates in a fully enclosed form, with no secondary pollution at all.

　　2. Low investment: No need to build pools and water storage boxes, no need to clean and disinfect frequently, saving more than 50% of construction costs and later cleaning and protection fees.

　　3. Less land occupation: There is no need to build ponds or water storage boxes, and the facilities take up less space. The vacated pool space can even be used as parking spaces, increasing revenue.

　　4. Energy saving: Fully utilize the pressure of urban management work pipeline network, make up for the difference and supplement the difference; When the water supply pressure meets the requirements, the facility is in a shutdown state. When the water supply pressure is insufficient, the facility starts working semi-automatic. Energy saving of 20% to 80% compared to traditional water supply facilities.

　　5. Stable water pressure: The outlet pressure is measured in real-time through sensor inspection, and variable frequency control is used to ensure that the outlet pressure is permanently fixed.

　　6. Easy and convenient installation: The complete set of facilities is factory installed, small in size, and can be directly connected to the inlet and outlet of the pipeline, with a short construction period.

　　7. Convenient management: The facilities operate fully semi-automatic, with features such as transfer, short circuit, overcurrent, water shortage, and semi-automatic reset.

　　The non negative pressure variable frequency water supply equipment takes the municipal pipeline network as the water source, fully utilizes the existing pressure of the municipal pipeline network, and forms a closed continuous relay pressurized water supply method. It has good energy-saving effect and no secondary pollution of water quality. It is the development and extension of variable frequency constant pressure water supply equipment. Directly stacking water supply on the basis of municipal pipeline pressure saves energy, and also has many advantages such as fully enclosed, pollution-free, small land occupation, fast installation, reliable operation, and easy maintenance.
