Water collection tank is an important water collection equipment in water supply and drainage engineering. Water collection tanks are mainly divided into perforated water collection tanks and triangular weir water collection tanks according to their structural forms. Its material can be stainless steel, carbon steel, fiberglass, etc. The water collection tank produced by our company is bent by a large bending machine in one go, avoiding unnecessary welding processes. The slot holes are uniformly punched by a punch press to ensure the accuracy of the opening. To enhance the strength of the groove, there are folded edges on the sides of the groove, which are both aesthetically pleasing and sturdy. After the stainless steel water collection tank is made, it is acid washed and passivated to improve its corrosion resistance, while also making the tank body look smooth and beautiful. When installing the water collection tank, its elevation accuracy can be controlled within ± 2mm, effectively ensuring that the water collection tank collects water evenly. The elevation of the weir plate of the adjustable triangular weir collection tank can be adjusted arbitrarily, which can avoid the impact of uneven settlement in civil engineering.
