1、 Product Overview:

A non negative pressure steady flow tank (negative pressure eliminator steady flow compensation tank, etc.) is a type of tank specifically designed for non negative pressure water supply equipment. The non negative pressure tank is equipped with a vacuum suppressor at the top of the tank, with the inlet connected to the tap water pipeline and the outlet connected to the inlet of the water pump. Due to the function of the vacuum suppressor, the interior of the tank maintains positive pressure in any working state, avoiding the direct extraction of water from the tap water pipeline by the water pump, protecting the water pump, and avoiding water shortage for users.

2、 Product features:

1. Excellent Material: The non negative pressure tank produced by our company is made of stainless steel materials such as 304 and 316, with oval heads on the top and bottom. It has undergone precision manual mirror polishing treatment, resulting in a beautiful appearance.

2. Precision welding process: The tank body interface is welded using argon arc welding, mainly including fish line welding and seamless welding, both using stainless steel beads of the same material as the stainless steel tank body as the welding material. Good welding effect, able to withstand pressure of 6Mpa or more.

3. Polishing treatment: All stainless steel components are polished and then sandblasted or sprayed to give the non negative pressure water supply equipment a brand new look.

3、 Vacuum Suppressor:

A vacuum suppressor is an essential device without negative pressure. Its function is to prevent vacuum and pressure imbalance in the series pipeline network when the municipal tap water supply flow rate is less than the user water flow rate.

4、 Working principle:

As tap water continuously enters the tank, the air inside the tank is automatically discharged through a vacuum suppressor as the water level continues to rise. When the water level rises to a certain level, the vacuum suppressor automatically shuts off. At this time, tap water continues to enter, and the pressure inside the tank gradually increases until the final pressure inside the tank is equal to the pressure of the tap water pipe network. When the user's water usage increases or the flow pressure of the tap water network decreases, the water level inside the tank will gradually decrease. When the water level drops to a certain value, the vacuum suppressor will automatically open, connect to the atmosphere, and there will be no negative pressure inside the tank. The water pump will extract water from the tank. When the user consumes a large amount of water, the tap water pipe has a small volume, or the tap water stops running, the liquid level controller on the tank controls the stop or start of the water pump.
