The water ejector is the fundamental source of negative pressure in the entire chlorination system and is key to the injection of chlorine gas after it combines with water. The performance of the water ejector directly affects the stability of the system's operation. Water ejectors are widely used for injecting chemical solutions into pressure pipelines, offering advantages such as simple installation and operation, ease of use, and reliable performance. They are suitable for the injection of various types of chemicals at different dosages and are a cost-effective injection component. Different models are available based on the required dosing volume. Working principle: When high-pressure water is ejected from the nozzle of the water ejector into the throat tube, the high-speed flow of water creates a pressure difference with the surrounding fluid. The faster the flow rate, the lower the pressure, the higher the vacuum, and the stronger the suction force. Under the action of high-pressure water, the water ejector draws in gaseous or liquid chemicals, forming a mixture of water and chemical that is injected into water pipes or pools.
