Non negative pressure variable frequency water supply equipment, household variable frequency water supply equipment, variable frequency water supply equipment, usage

Description :

Non negative pressure frequency conversionWater supply equipmentIt is a water supply equipment composed of a non negative pressure device, a pump group, and a control cabinet. The stabilizing device is a closed structure, and the closed flow regulator is a tank type pipe network stacking (non negative pressure) device. The system equipment is connected in series to the area where the pressure of the municipal tap water pipe network is insufficient. The equipment detects the outlet pressure through a pressure sensor, compares the detection value with the set value, calculates the pressure value that needs to be added on the basis of the original pressure of the municipal tap water pipe network, determines the number of water pumps to be put into operation and the output frequency of the frequency converter (reflected in the speed of the motor and water pump) to achieve constant pressure according to the water curve. The non negative pressure variable frequency water supply equipment maximizes the use of the original pressure of the municipal tap water pipe network, does not generate negative pressure on the municipal tap water pipe network, and replaces the old water Secondary pollution of water, It is a new generation of energy-saving products in the field of water supply.

　　1. No negative pressure:

　　The direct connection between the system and the municipal water supply network for pressurized operation will not cause negative pressure in the municipal water supply network;

　　Intelligent computer programming control;

　　◆ Independently developed, with diverse functions, able to provide level of control, has reached a certain level

　　2. Stacking:

　　The equipment relies on the pressure of the municipal water supply network during operation, and on this basis, it is pressurized. Compared with absorbing water from ordinary reservoirs, it can reduce the number of pumps or lower the speed during operation to achieve energy-saving goals;

　　3. Maintain a constant pressure:

　　The equipment detects the outlet pressure in real time through a pressure sensor, compares and calculates the detected and set values, determines the number of water pumps to be put into operation, and determines the output frequency of the frequency converter (reflected as the speed of the motor and water pump) to achieve constant pressure

　　4. Stable water supply:

　　When the power supply line experiences a power outage, the system achieves uninterrupted water supply through a bypass pipeline, which means that the system automatically switches to municipal tap water pressure supply during the power outage.

　　5. Safety and hygiene:

　　The overcurrent components are made of food grade materials such as stainless steel, which comply with international water safety regulations.

　　6. Highly intelligent:

　　The system can achieve fully automatic control, with functions such as manual/automatic switching, timed rotation of main and auxiliary pumps, pressure adjustment, constant voltage, high and low voltage protection, under phase protection, leakage protection, overload protection, overheating protection, water shortage protection, stopping without water, and instantaneous trip protection. Alternatively, the human-machine interface can be configured according to user needs, allowing for visual remote adjustment, detection, and maintenance.

　　7. Save investment:

　　The system does not have civil water storage facilities such as reservoirs, which saves land area and reduces building load capacity, thus greatly reducing investment costs.

　　8. Save operating costs:

　　The system ensures constant pressure in the pipeline by adjusting the number of units and operating speed according to changes in water consumption. When the water consumption is high, the input power is high, and when the water consumption is low, the input power is low. When the water consumption is low (such as at night), the system is supplied with a low-power pump with variable frequency speed regulation and constant pressure water supply. The system has been running continuously, greatly reducing operating costs and saving over 60% of energy.

　　The system runs fully automatically without the need for dedicated personnel to be on duty; Due to the lack of civil water storage facilities such as reservoirs and water quality treatment equipment, regular cleaning and disinfection work are avoided. Therefore, it further reduces operating costs.

　　If there is a certain pressure in the municipal pipeline network, it only needs to be pressurized on the basis of the municipal pressure during operation. Compared to traditional water supply equipment with reservoirs, it achieves the same effect with less power drawn from the power grid. The energy-saving effect is very significant.
