1. Saving investment Small footprint? The variable frequency constant pressure water supply equipment system does not have civil storage facilities such as reservoirs, which saves the floor space and reduces the load carrying capacity of the building, thus greatly reducing the investment cost. The system ensures that the constant pressure of the pipeline is adjusted according to the change of water consumption and the running speed of the pump. When the water consumption is large, the input power is large, and the water consumption is small when the water consumption is small. When the water consumption is small (such as at night), the system is supplied by the air pressure tank or the small flow pump. The system has been running at high efficiency points, thus greatly reducing operating costs. It can save more than 60% of energy. If the municipal pipe network has a certain pressure, it is only necessary to apply pressure on the basis of the pressure of the municipal pipe network during operation. The same effect is achieved compared to a conventional water supply with a reservoir, while the power drawn from the grid is less. The energy saving effect is very significant. The automatic operation of the system does not require special personnel to be on duty, and the closed operation will not cause secondary pollution, eliminating the need for regular cleaning and disinfection, thus further reducing operating costs.
2. Sanitary Overflow parts are made of food grade materials such as stainless steel, which conforms to national wading sanitary regulations. The box type non-negative pressure device can ensure that the water stored in the water tank is automatically updated every day through the user's water, and the tank type non-negative pressure variable frequency constant pressure water supply equipment is replaced to ensure water sanitation.
3, highly intelligent automatic automatic control, with manual / automatic switching, primary and auxiliary pump timing rotation, pressure adjustment, constant pressure, high and low voltage protection, phase loss protection, leakage protection, overload protection, overheat protection, water shortage protection, no Water parking sleep, instantaneous trip protection and other functions. In addition, the man-machine interface can be configured according to user requirements to visualize remote adjustment, detection and maintenance.
4. When the power supply line of the water equipment is out of power, the power supply is continuously shut down by means of bypass, etc., that is, the system automatically switches to the municipal tap water pressure supply when the power is cut off.
5. Maintain a constant pressure to detect the outlet pressure through the pressure sensor in real time, and compare the detected value with the set value to determine the number of motors and pumps and the output frequency of the inverter (reaction is the motor and pump speed) to achieve constant pressure water supply. purpose.
6. By means of pressure (or stacking) equipment, the pressure of the municipal water pipe network is used during operation, and the pressure is increased on the basis of this, and the number of water pumps can be reduced or the pump speed can be reduced when running compared with water absorption from a common reservoir. Energy saving purposes.
7, no negative pressure frequency conversion constant pressure water supply equipment system in the municipal water pipe network direct water pressure operation will not cause negative pressure on the municipal water pipe network. High-quality intelligent microcomputer control, dedicated and self-developed with diversified functions, capable of providing cutting-edge precision control, has reached the leading level in the same industry.
