Four technologies for non-negative pressure water supply equipment

Four technologies of non-negative pressure water supply equipment Non-negative pressure water supply equipment is a pressurized water supply unit that is directly connected to the municipal water supply pipe network, and is connected in series on the basis of the remaining pressure of the municipal pipe network to ensure that the pressure of the municipal pipe network is not less than the setting The secondary pressurized water supply equipment with protection pressure (it can be 0 pressure of relative pressure, and negative pressure when it is less than 0 pressure). One: Exclusive negative pressure elimination technology double insurance; on the basis of the original negative pressure elimination technology, a negative pressure suppressor works to control the generation of negative pressure, and an emergency air intake to eliminate negative pressure is added on this basis. One-way channel; two negative pressure elimination functions. When the suppressor cannot completely eliminate negative pressure or malfunction, the other emergency air intake channel for eliminating negative pressure is opened immediately, 100% completely eliminates the generation of negative pressure. Two: Exclusive double protection for anhydrous detection; when the municipal pipe network stops water, the water level in the steady flow tank drops, and when the liquid level sensor detects an anhydrous signal, it immediately gives the signal a secondary non-negative pressure water supply equipment inverter to let the water pump Stop working to protect the water pump to prevent the motor from burning out. The water pump automatically restores water supply when water comes in. The second type of protection: when the liquid level sensor fails, the electric contact pressure gauge under the non-negative pressure steady flow tank works; when the pressure gauge detects that the pressure at the inlet of the water pump drops to the set pressure; the pressure signal is fed back to the inverter to allow the water pump Immediately reduce the frequency and work until it stops to prevent the motor from burning out, protect the pump, and automatically restore the water supply when the water comes in. Three: Exclusive water pump outlet elbow flow channel no scar technology: secondary non-negative pressure water supply equipment pump outlet flow channel uses exclusive special The extended big moon elbow eliminates the conventional 90-degree elbow re-welding pipe method, and the water outlet flow channel of the pump is smoother, reducing the head loss and improving the working performance of the pump. It is not only beautiful but also very practical. Four: Exclusive special liquid level sensor replacement product: At present, the liquid level sensor on the non-negative pressure tank is made of stainless steel 304 or 316. It has been proved over the years that many users have found that it is installed in the secondary Non-negative pressure water supply equipment stainless steel steady flow tank filling liquid.
