What is the difference between non-negative pressure water supply equipment and constant pressure water supply equipment?

There are three main differences between non-negative pressure water supply equipment and constant pressure water supply equipment:

First of all, from the product hardware.

Non-negative pressure water supply equipment includes: water pump, negative pressure tank, pneumatic tank, pipeline valve and channel steel base. Constant pressure water supply equipment includes: water pump, stainless steel water tank or pool, pneumatic tank, pipeline valve and channel steel base.

Second, from the perspective of product energy saving.

Because these two kinds of equipment are operated by frequency conversion, frequency conversion energy saving in some places is not mentioned. Non-negative pressure water supply equipment can superimpose the existing pressure of municipal pipe network, but constant pressure water supply equipment can't. Therefore, on the whole, the energy-saving effect of non-negative pressure water supply equipment is better than that of constant pressure equipment.

Third, from the product water source.

Non-negative pressure water supply equipment is directly connected with the municipal tap water pipeline. If the tap water is cut off, the equipment will also be cut off. Constant pressure water supply equipment is that tap water is pressurized by stainless steel water tank, which has a specific water storage function, so the water supply is temporarily stopped, and the water supply in the equipment community is not stopped.
