Product overview
The traditional way of water supply is inseparable from the reservoir, the water reservoir in general supplied by the municipal water supply pipe, so the pressure water into the pool becomes zero, caused a lot of waste of energy.
WZG type (tank) intelligent pipe network pressure (no negative pressure) water supply equipment is developed by our professional technical personnel on the basis of air pressure water supply equipment, can be directly connected with the water pipe network, and the water pipe network does not produce any negative effect of complete sets of water supply equipment. The water supply device composite of intelligent control cabinet, pressure tank, water pump, flow meter, a valve and a pipeline and a base. The combination of pressure tank using food grade stainless steel material, no pollution, to ensure water security.
Working principle
The equipment put into use, water pipe network water enters the pressure tank, when sufficient municipal pressure, flow tank is direct replenished by the bypass pipe to the user, no need to start the pump; when the water users increases, water pipe network pressure can not meet the water requirements, start frequency conversion pump pressurized supply user. At this time signal system consists of a pressure sensor feedback to the frequency conversion controller, through systematic analysis to convey the signal to start the pump, and according to the water consumption volume, automatically adjust the pump speed, to ensure the constant pressure water supply, if the operation of the pump speed to power frequency, Thus, move the other pump frequency operation.
When pump water supply, if the amount of water in the water pipe network is greater than the pump flow, to maintain system normal water supply; peak time for water use, if the water pipe network water is less than the pump flow rate and the water of pressure tank as a supplementary water source to supply water normally, by vacuum inhibition system and a unique non negative pressure protection device (patent technology), we safely and sustainably supply water to the user to ensure that the municipal pipe network are not generated negative pressure; after the peak water, the system returned to normal water again.
When water pipe network water shut, resulting in declining level of the pressure tank, liquid level detector will feedback signals to the frequency conversion controller, water pump automaticly stop, to protect the pump unit.
Night small flow of water supply and water pipe network pressure can not meet the requirements, can be stored and released by the bypass pipe pressure tank and release energy, so that small flow pressure to avoid frequent start pump.
WZG (irrigation) intelligent pipe network pressure (no negative pressure) water supply equipment used for all the need to increase the water pressure, constant flow of water supply system. If the water supply equipment is connected in series in a municipal tap water pipe network when pressure is insufficient, equipment checked through the outlet pressure of the pressure sensor, after this immediately detection and set value, control module is automatically calculated on the basis of the pressure of the municipal pipe network increase the pressure value need to, confirmed water pump units put into operation and output frequency of the inverter, so as to realize the running of water pump outlet and the network pressure superposition, to ensure compliance with water curve close to the constant pressure of pipeline. This water supply equipment to maximize the use of the original pressure of the municipal pipe network, can replace the old irrigation water supply equipment or water tank model, and to avoid the two waste of energy and two pollution, greatly saving the infrastructure investment and shorten the construction cycle.
WZG type (irrigation) intelligent pipe network pressure (no negative pressure) water supply equipment is a new generation of energy-saving products in the field of water supply.
application range
Pressure technology suitable for areas with inadequate water pressure:
New residential or office buildings, such as the use of water.
Low level running water pressure can not meet the requirements of the fire water.
Transformation of a good pool, you can use the non negative pressure equipment and the pool of water supply in a common way to further energy saving.
Water supply intermediate pressure pumping station.
Production of industrial and mining enterprises, domestic water, etc..
