Non negative pressure pipe network stacked water supply equipment

The non negative pressure pipe network stacked water supply equipment uses the principle of microcomputer frequency converter and negative pressure solution technology to achieve non negative pressure power supply. Based on the operation status displayed on the electronic display screen, the vacuum pump compensation system software and fully enclosed structure are used to immediately connect with the drinking water pipe network, eliminating the negative impact on the pipe network.

　　
Principle of non negative pressure pipe network stacked water supply equipment
　　
Adjust the frequency of the soft starter using negative pressure feedback based on the inspection of pipeline pressure using a microcomputer. First, set the working pressure of the tap water point according to the specific situation, check the specific pressure of the water outlet and compare it with the set pressure, and then adjust the frequency of the soft starter. Microcomputer can check the pressure of the pipeline anytime and anywhere. The processing speed is fast. The adjustment rate is also made instantly to maintain the pipeline pressure at the set standard value continuously. The fully enclosed construction and negative pressure feedback suppression system software enable the system software to immediately connect with drinking water. By applying the superposition theorem in the operation of the water pump, the machine equipment can flexibly use the original pressure of drinking water, improving the performance of the DC variable frequency variable speed water supply and drainage machine equipment. When the pressure of drinking water is insufficient and causes a decrease in pressure, this machine collects the vacuum value and water level data signal inside the steady flow pipeline compensator based on the inspection equipment in the vacuum pump suppressor and steady flow pipeline compensator. It controls the unique equipment posture in the vacuum pump suppressor and steady flow pipeline compensator based on the microcomputer to suppress negative pressure and ensure that the system software does not cause any harm to the urban pipeline network.
　　
When the drinking water supply pressure P1 of the municipal engineering pipeline network is lower than the customer's required pressure P2, the automatic control system will automatically control the operation of the variable frequency pump until it can meet the customer's pressure requirements, and operate the pump at a stable speed ratio to carry out variable frequency constant pressure water supply. When the water demand increases, the speed ratio increases, and when the water demand decreases, the speed ratio decreases, ensuring stable tap water pressure for customers at all times. The lower the pressure of drinking water, the higher the speed ratio of the water pump; The higher the pressure of drinking water, the lower the speed ratio of the water pump. When the pressure of the drinking water is not less than the pressure required by the customer, the water pump stops running. When several pumps are operated, the control board will automatically start the second water pump, the third water pump... until the customer pressure preset value is reached, and then maintain variable frequency constant pressure water supply. Overheated steam power supply for repairing drinking water during power outages.
　　
When supplying power, if the water flow of the drinking water pipe network matches the total flow of the water pump, the machinery and equipment will be powered normally. During peak hours of tap water supply, if the water flow rate in the drinking water network is lower than the total flow rate of the water pump, the water in the non negative pressure stable flow tank can still provide normal power supply as a filling water resource. At this time, gas enters the tank through the vacuum pump controller, and the vacuum pump in the tank is damaged, ensuring that the drinking water network does not cause negative pressure tap water. After that, the system software restores the power supply situation.
　　
The non negative pressure pipe network stacked water supply equipment can immediately connect to any pipe network with insufficient drinking water pressure for pressurized power supply, and should not have a reservoir. In addition, it can also eliminate the need for disinfection machines that require capital investment due to secondary pollution.
　　
The non negative pressure pipe network stacked water supply equipment places domestic water sources into underground daily water storage tanks, and then uses water pumps to pressurize and supply power to various tap water points. The original design of the pressurized power supply method resulted in the waste of drinking water's original power supply pressure. And the non negative pressure pipe network stacked water supply equipment is immediately connected to the drinking water pipeline network, which can flexibly use the original pressure of the drinking water pipeline network; The motor pump of the machine equipment is operated by a microcomputer to adjust the speed ratio of the motor based on the pressure of the drinking water, and only applies pressure to the difference between the seepage pressure of the drinking water and the required pressure, without making any arbitrary decisions; When the water demand is high, the tap water is immediately supplied to the customer by the pressurization machine equipment. When the total flow rate is small or there is no tap water, the non negative pressure pipe network stacked water supply equipment is checked for data signals by the microcomputer monitoring center, and the automatic control system automatically shuts down and solidifies.
　　
The non negative pressure pipe network stacked water supply equipment thoroughly simulates the human brain's intelligent technology for automatic operation of machine equipment, and has various maintenance functions such as overvoltage, overcurrent, load, water shortage, video and voice alarms, etc; And the machine equipment can be configured with real-time monitoring and detection systems according to customer requirements for real-time monitoring and supervision. It can also help customers create a centralized monitoring system to detect pump current, working voltage, inlet and outlet pressure, pump frequency, etc. Once abnormalities are detected, the machine equipment will immediately sound an alarm. Some soft faults (such as common faults caused by sudden interference signals, fluctuations in working voltage, etc.) can be cleared based on real-time monitoring; In addition, the monitoring system can also remotely operate the start and stop of machine equipment.
　　
The non negative pressure stacked water supply equipment is the seventh generation product upgraded and developed based on the original variable frequency non negative pressure stacked water supply equipment and non negative pressure stacked water supply equipment. It consists of a stainless steel water tank, a dedicated water pump, an intelligent variable frequency control cabinet, a non negative pressure device, a boosting device, a water diversion device, and a stabilizing tank. It is a new type of electromechanical integrated water supply equipment that combines computer technology, variable frequency technology, and motor pumps. To meet the requirements of urban water supply network, which not only does not generate negative pressure during pumping, but also has a certain capacity for regulating and storing water, and continuously stops water supply during peak periods. Using a microcomputer controlled variable frequency pump to operate at a constant speed and utilizing the existing pressure of tap water can ensure that the pressure required by the user is constant. It has the advantages of energy saving, environmental protection, low noise, and constant water supply pressure.
　　
The properties and functions of non negative pressure water supply equipment and variable frequency constant pressure water supply equipment are the same, both playing the role of constant pressure. From a microscopic perspective, non negative pressure water supply equipment also belongs to variable frequency constant pressure water supply equipment, and from a macroscopic perspective, variable frequency constant pressure water supply equipment is also a non negative pressure water supply equipment.
　　
Why is it said that the properties and functions of non negative pressure water supply equipment and variable frequency constant pressure water supply equipment are the same at the macro and micro levels? Because non negative pressure water supply equipment is directly connected to the tap water pipe, and has a steady flow tank with vacuum suppressors, pressure detection devices, and water shortage protection devices. When tap water cannot be supplied or has fallen below the rated pressure, the equipment will automatically stop supplying water to protect the pipeline network. The operation of the two non negative pressure water supply equipment is controlled by a variable frequency control cabinet, which controls the number and frequency of working pumps to achieve the effect of constant pressure water supply. Therefore, non negative pressure water supply is also constant pressure.
