Frequency conversion non negative pressure water supply equipment frequency conversion non negative pressure water supply equipment selected manufacturers direct sales

  Intelligent frequency conversion non negative pressure water supply equipment, also known as intelligent frequency conversion laminated water supply equipment, takes tap water as the water source and makes full use of the pressure of tap water pipe network to realize & ldquo; Make up for the difference & rdquo; Continuous pressurized water supply mode
A pressure tank is connected in series on the equipment inlet pipeline to buffer and compensate the municipal pipe network and prevent negative pressure, so as to prevent excessive suction to the municipal pipe network

 
Functional features of intelligent frequency conversion non negative pressure water supply equipment: 1
During operation, the laminated energy-saving non negative pressure water supply equipment uses the pressure of municipal tap water to superimpose the required pressure difference on the basis of the original pipe network pressure
How much is the difference and how much is the supplement? Make full use of the residual pressure of the pipe network, and the system automatically adjusts the number of water pumps or the speed of water pumps to realize the high-efficiency operation all the time
When the inlet pressure can meet the design pressure, the water pump enters the dormant energy-saving state, so the operation cost is greatly saved 2
The pressure control non negative pressure water supply equipment detects the outlet pressure through the pressure sensor in real time, compares the detected value with the set value, calculates the pressure value to be increased based on the residual pressure of the municipal self incoming water pipe network, determines the number of water pumps and the output frequency of the frequency converter, and adjusts the speed of the water pump to realize the control of superimposed constant pressure water supply or superimposed variable pressure water supply
3
With high degree of automation, it has the functions of manual start and stop, automatic start and stop mode, reserved remote operation interface, automatic switching of standby pump, pressure control (constant voltage / variable voltage), high and low voltage protection, leakage protection, trip protection, overload protection, overheating protection, under phase protection, etc
the system operates fully automatically without special personnel on duty, and the man-machine interface can be adjusted remotely Monitoring and maintenance 4
Health, safety and sealed operation
Foreign matters cannot enter the system and will not be in direct contact with the air
For example, when the anti negative pressure device is started, the membrane filtration device blocks the bacteria in the air from entering the system to prevent secondary pollution of water
The steady flow tank and main flow passage components are made of 304 stainless steel to ensure water sanitation, meet people's higher and higher requirements for drinking water, and also comply with international water related sanitation standards
5
Without power failure, the water is directly connected with the municipal tap water pipe network
Although the booster pump stops working in case of power failure, the pressure of the tap water pipe network can still maintain the water supply of users in low areas
Even in case of water failure, users can maintain the water supply for a short time by filling and storing water with stable flow
6
Water cut-off or water shortage protection when there is water cut-off or water shortage, the non negative pressure water supply equipment stops running
When the equipment recovers water inflow and reaches the set conditions, the equipment will automatically resume normal operation
7
Save investment, operation and maintenance costs, no water storage facilities such as reservoirs, save floor area and reduce building load, so as to save a large amount of civil engineering investment
The system operates automatically without special personnel on duty, and there is no water treatment instrument, which eliminates the work of regular cleaning and disinfection; The loss of dripping, leakage and profit flow of the system is reduced
Therefore, the energy-saving effect is very significant
8
The installation is simple and fast
The non negative pressure water supply equipment only needs to assemble the large parts of the equipment on site and connect the inlet and outlet pipe flanges
The construction cycle is short and the installation is simple
