No negative pressure water supply equipment four technologies.

No negative pressure water supply equipment four technologies.

No negative pressure water supply equipment is a kind of pressurized water supply unit directly connected to municipal water supply network, in the municipal pipe network based on the residual stress in series the overlying water and ensure the municipal pipe network pressure set is not less than protection (can be a relative pressure zero pressure, less than zero pressure called negative pressure) of secondary pressure water supply equipment.
1. Exclusive elimination of negative pressure technology double insurance;
On the basis of the original elimination of negative pressure technology, a negative pressure suppressor was employed to control the negative pressure generation. On the basis of this, a one-way one-way channel was added to eliminate the negative pressure.Two kinds of elimination of negative pressure function, when the suppressor cannot completely eliminate the negative pressure or the failure, another eliminates the negative pressure emergency intake channel to open immediately, 100% completely eliminates the negative pressure generation.
2. Double protection without water detection;
Steady flow when the municipal pipeline network of water tank water level drops, liquid level sensor detects the anhydrous signal, immediately to signal the secondary inverter has no negative pressure water supply equipment, stop the pump work, protection of water pump, to prevent motor burn down, when the water pump automatically restore water supply.The second type of protection: when the liquid level sensor fails, the pressure gauge is operated by the electric contact point under the non-negative pressure steady flow tank;When the pressure gauge detects the pressure drop setting pressure of the inlet pressure of the pump;The pressure signal is fed back to the frequency converter, so that the water pump can reduce the frequency immediately, until the machine is shut down to prevent the motor from burning, protect the water pump, and automatically restore the water supply when the water comes in.
3. No scar technology for the outlet of the exclusive pump outlet:
Secondary pump no negative pressure water supply equipment export port use exclusive special extension monthly elbow, cancelled the regular 90 - degree bend welding pipe way again, the pump outlet port more unobstructed, reduced the head loss, improve the pump performance, not only beautiful and very practical.
Iv. Exclusive special liquid level sensor replacement products:
The current domestic production of no negative pressure tank liquid level sensor are stainless steel 304 or 316 materials products, over the years has proved that many users are found in secondary no negative pressure water supply equipment, stainless steel fluid of steady flow tank.
