Introduction to Water Dispenser:

A water collector, also known as a separate water collector, is a water flow distribution and concentration device composed of a collector and a water distributor. A water distributor is a device that disperses the incoming water into several output channels, while a water collector is a device that gathers the incoming water into several output channels. The structure is composed of a main pipe, branch pipes, sewage outlets, exhaust outlets, pressure gauges, thermometers, etc., and a cylinder with a larger diameter is equipped with a manhole or handhole. The material is made of carbon steel plate or welded steel pipes, which can withstand a certain pressure. It belongs to the pressure vessel industry manufacturing, and the outer surface is treated with anti-corrosion or insulation. The cylinder of the water collector is connected to an inlet and outlet pipe as needed, which can collect or divert water from various channels. The cylinder is equipped with a pressure gauge or thermometer, which can facilitate the observation of the water flow status inside the cylinder. The lower end of the cylinder is equipped with a drainage outlet, which is used for the discharge of sewage during the cleaning of the cylinder. Its models range from DN2000 to DN1500. It allocates the flow of water from the main pipeline as needed, ensuring that the flow of branch circuits in each region meets the load requirements. At the same time, it also collects the water flow from each branch circuit and inputs it back into the main pipeline for circulating operation. The reuse of its return water can achieve energy-saving results and simultaneously meet the needs of heating and cooling. It is applied in boilers, central air conditioning, industrial circulating cooling water systems, and hot water systems. It is different from other air conditioning systems such as heat exchange units and vacuum degassers, and the water collector is mainly used in water systems.
