System innovation function

1、 Water supply window system The water supply window software used adopts a touch based operation mode on the human-machine interface, which displays the working status, real-time pressure, frequency conversion, various fault displays, modified operating parameters, and system parameters of each pump on site in the corresponding screen (page number) of the window. The organic combination of text, numbers, and graphics enriches the content of the system and increases its integrity, making it easier, more intuitive, and accurate for operators to grasp the system's operating status, greatly improving the reliability of the system. There are multiple interfaces left on the window system for necessary upgrades and corresponding communication functions.

2、 Voice alarm system The device can be equipped with a remote voice alarm function. When the device control system fails, the system triggers an alarm on the pre-set fixed telephone or voice notification to the management personnel that the device needs to be repaired in a timely manner to avoid affecting the normal use of water by users. This control function requires the use of a telephone line for dialing.

3、 Remote control system The device can have a remote monitoring interface, utilizingGPRS/MODEMRealize wired or wireless remote control of equipment, real-time control of the working status, real-time pressure, frequency conversion and other system parameters of each pump in different locations, and perform alarm and memory processing for faults.

Pump box integrated pressurization equipmentWorking Principle:

1Pump box integrated pressurization equipmentAdopting microcomputer controlled variable frequency speed regulation to achieve constant pressure water supply.

2Pump box integrated pressurization equipmentSet a certain pressure value. If the municipal pipeline pressure is higher than the set pressure value, the pressure transmitter will send the signal to the variable frequency control cabinet to put the water pump unit in a sleep state.

3Pump box integrated pressurization equipmentTap water can be directly supplied to the user's pipeline network through connected pipelines. When the pressure of the municipal pipeline network decreases or the water consumption of the user pipeline network increases, the pressure sensor feeds back the signal that the pressure of the user pipeline network is lower than the set value to the PID controller in the frequency conversion control cabinet, and starts the water pump unit through it to adjust the output frequency of the frequency converter and adjust the pump speed to maintain constant pressure water supply.

4Pump box integrated pressurization equipmentIf a few pumps cannot meet the water supply requirements after starting, the frequency converter will control multiple pumps to operate at variable frequency or power frequency to achieve the requirement of constant pressure variable water supply.

5Pump box integrated pressurization equipmentWhen the water supply of the water pump unit is balanced with the water inlet of the tap water pipeline network, the negative pressure eliminator isolates the stabilizing compensator from the outside world, and the water pump unit can use the pressure of tap water for constant pressure water supply.

6Pump box integrated pressurization equipmentWhen the municipal pipeline network is shut down, the water pump unit can still continue to work until the water level in the stabilizing compensator drops to the lower limit of the liquid level, and then automatically shuts down. After water comes in, it automatically starts up again.

Changsha HuazhenPump box integrated pressurization equipmentProduct Brief

The traditional water supply method cannot do without a reservoir, and the water in the reservoir is usually supplied by the tap water network. In this way, the pressurized water enters the reservoir and becomes zero, resulting in a large amount of energy waste. Huazhen HZH typePump box integrated pressurization equipmentOur company's professional technical personnel are hereVariable frequency pressurized water supply pump for daily useA secondary pressurization system developed on the basis of, which can be directly connected to the tap water pipeline network and does not generate any negative pressure on the tap water pipeline networkNon negative pressure variable frequency booster pumpOn the basis of the original pressure, compensate for the pressure difference as much as possible. It can fully utilize the pressure of the tap water network to directly or indirectly supply water, avoiding secondary waste of energy and secondary pollution of water quality. It eliminates the need for water storage tanks and rooftop water tanks, greatly saving infrastructure investment and shortening construction period.Pump box integrated pressurization equipmentIt is a fully automated water supply equipment that is directly connected to the municipal water supply network, does not create negative pressure on the municipal pipeline network, and can regulate and stabilize the flow rate.Variable frequency pressurized water supply pump for daily useWorking principle: Tap water enters the regulating 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 tap water can meet the requirements of water pressure and quantity,Pump box integrated pressurization equipmentDirectly supplying water to the water supply network through water pump pipelines and bypass pipelines; When the pressure of the tap water network cannot meet the water requirements, the system sends a pump start signal through pressure sensors or remote pressure gauges to start the water pump 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,Variable frequency pressurized water supply pump for daily useMaintain normal water supply. During peak water usage periods, if the water volume in the tap water network is less than the pump flow rate, the water in the regulating tank can still be supplied as a supplementary water source. At this time, air enters the regulating tank through a vacuum eliminator, eliminating the negative pressure in the tap water network. After the peak water usage period,Variable frequency pressurized water supply pump for daily useRestore normal state. If the tap water supply is insufficient or the pipe network is shut down, causing the water level in the regulating tank to drop to zero, the liquid level controller will give a shutdown signal to protect the water pump unit. The water pump automatically resumes water supply when water comes in. Due to the use of variable frequency control technology, it has soft start, overload, short circuit, overvoltage, undervoltage, phase loss, overheating and stall protection, signal alarm in abnormal situations, self check, fault diagnosis and other functions. It also automatically adjusts the water supply flow according to the level of water consumption.
