Non negative pressure variable frequency water supply equipment Production of non negative pressure variable frequency water supply equipment Product characteristics

Description :

Non negative pressure variable frequency water supply equipmentProduct features: 1. Cost saving: Save about 50% of investment, no need to build reservoirs or roof water tanks, adopt stacked water supply, reduce initial equipment investment. 2. Efficient and energy-saving, with low operating costs: It can fully utilize the water supply pressure of the municipal pipeline network, adjust the difference and supplement, without generating negative pressure, and can save 30% -90% energy compared to traditional water supply equipment. Power outages can also maintain the water pressure and supply of the municipal pipeline network. 3. High degree of intelligence, simple operation, and labor-saving: The device is controlled by a fully automatic intelligent controller, which adjusts itself according to the user's water consumption and the tap water pressure of the pipeline network, and is unmanned. And it adopts a human-machine interface (text, numbers) display, allowing customers to more intuitively see the operation status of the equipment. 4. Environmental hygiene: The equipment operates in a fully enclosed manner, completely eliminating secondary pollution of the water source. 5. Complete protection functions: It has perfect automatic protection functions for overload, short circuit, overvoltage, undervoltage, phase loss, overcurrent, short circuit, water source shortage, etc. Can perform signal alarm, self check, fault diagnosis, etc. in abnormal situations. 6. Small footprint and easy installation: The entire equipment consists of only one set of water supply control cabinet, non negative pressure stabilizing tank, and water pump unit, making installation very simple and convenient. 7. Extend the service life of the equipment: It can reliably achieve soft start for multiple pump units, avoiding impact on the power grid and pipeline network, and rotating them alternately, greatly extending the service life of the water pump and motor. The lifespan of the equipment can be extended by more than three times.

　　Working principle of non negative pressure variable frequency water supply equipment: When the non negative pressure variable frequency water supply equipment is put into use, the water in 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.
