WFY series non-negative pressure lamination steady flow water supply equipment is a complete set of water supply equipment developed by our company's technical staff on the basis of domestic variable frequency water supply equipment, which can be directly connected to the water pipe network without causing any side effects to the water pipe network. Under normal circumstances, it can replace the reservoir, can make full use of the pressure of the water pipe network to directly supply water or relay water, avoid secondary pollution and waste of energy, greatly save infrastructure investment and shorten the construction period. WFY series non-negative pressure lamination steady flow water supply equipment is composed of variable frequency control cabinet, steady flow tank, pump unit, instrument, valve, base and connecting pipeline, etc. It is suitable for running water pipe network, which needs to increase water pressure and constant flow. Water supply system.
1. When the pressure Pz of the tap water is lower than the set pressure Py required by the user, the programmable controller will automatically run with frequency conversion and soft start until the actual pressure of the pipeline Pz = Py. The programmable controller controls the variable frequency pump to run at a constant speed. The tap water pressure Pz is extremely high, the lower the speed of the frequency conversion pump, and the lower the tap water pressure Pz, the higher the speed of the frequency conversion pump. When the pressure of tap water Pz = Py, the variable frequency pump stops working. Not only make full use of the original pressure of tap water, but also ensure that the user needs a constant pressure.
2. The water inlet of the variable frequency pump is connected to the non-negative pressure tank. The programmable controller always detects the pressure in the non-negative pressure tank. So as to ensure the normal water supply of the water pipe network.
3. The tap water stops, the equipment automatically shuts down, the tap water starts automatically, and the power supply of the tap water is automatically restored when the power fails.
Conditions of Use:
1. There is no need to build a pool, a water tank and a tap water pipe network to directly connect the pressurized water supply, which can make full use of the original pressure of the tap water.
2. The quality of water supply is improved. Pure tap water is directly supplied to the user after being pressurized by the equipment. There is no anti-corrosion treatment of the negative pressure tank. The connection is sealed. The water source is not polluted. The water quality is good. Secondary pollution problem.
3. Energy saving effect is 50% ~ 90%.
4. Significant water saving. Overcome the phenomenon of running, running, dripping, leaking, and seepage in the pool.
5. There is no need to build a pump room or a pool. Reduce investment by more than 60%.
6, improve the quality of water supply constant pressure. Solve the problem of secondary pollution.
7. The equipment is ordered to extend more than 5 times.
8. Power failure without stopping water (recovering the pressure water supply of the original pipe network).
9, fully automatic operation.
Structural characteristics and working principle:
1. Living water in newly built residential quarters or office buildings.
2. Low-level tap water pressure cannot meet the requirements of fire fighting water.
3. Transform the original pneumatic water supply equipment. Can make full use of the original air pressure tank.
4. The water supply method shared by the non-negative pressure equipment and the pool can be used for the pool that has been built. Further energy savings.
5. Large intermediate pressure pumping station in waterworks.
6. Production and domestic water of industrial and mining enterprises.
7. Various circulating water systems.
When the equipment is put into use, the water from the tap water pipe network enters the steady-flow tank. After the water fills the steady-flow tank, the pump runs. In the initial stage of the pump operation, there will be an imbalance between the amount of water entering and the output. The destroyer works to avoid the generation of negative pressure in the steady flow tank, so that the operation of the equipment does not affect the normal water supply of the pipe network. When the pump is running, the system pressure signal is fed back to the frequency conversion controller by the pressure sensor, and the speed is automatically adjusted to achieve constant pressure water supply according to the amount of water consumption. If one pump cannot meet the requirements, two pumps will run at the same time with variable frequency. When the water pipe network stops, causing the liquid level in the steady-flow tank to drop continuously, the liquid level detector feeds back the signal to the variable frequency controller, and the pump automatically stops to protect the pump unit.
