Does the high-pressure pump of the industrial edi pure water treatment equipment have the function of manually adjusting the door? Author: edi industrial water treatment equipment is composed of a reverse osmosis system, and thus virtually free of impurities, contamination of the membrane element is not a problem. In actual use, except for the influent water of the secondary reverse osmosis system using the product water of the primary reverse osmosis system as the raw water, the influent water of other reverse osmosis systems is almost all the raw water after ordinary pretreatment. Although the pretreatment process removes some of the impurities, the quality of the influent water is still poor compared with the water source under the standard test conditions. An important component of the reverse osmosis system is the high-pressure pump. The following editor will introduce why the industrial edi pure water treatment equipment should be equipped with manual adjustment doors and electric slow-opening doors behind the high-pressure pumps? In actual use, follow the membrane element manufacturer The provided design guidelines are used, but the reverse osmosis membrane element will still be slowly contaminated. Of course, its performance can be partially restored by chemical cleaning after a period of time, but it is difficult to fully restore its performance, so experienced designers are designing This issue should be taken into consideration when the system is in operation. At this time, a feedwater pump that can guarantee the designed water output after 3 years should be selected, that is, a higher pressure feedwater pump needs to be designed, but the system does not need to be high pressure when it is initially put into operation. The water output is designed so that the pressure of the feedwater pump is rich during the initial operation of the system. As time goes by, the pressure richness gradually decreases. Therefore, a manual adjustment gate should be set behind the high-pressure pump to adjust the feedwater pressure. In some cases, a frequency conversion adjustment device can be installed on the feed water pump. In this case, the frequency conversion method can be used to realize the adjustment of the feed water pressure. The manual adjustment door behind the high-pressure pump generally does not need to be adjusted frequently after it is set up. It is basically kept at a constant position for a period of time, and there is no need to open and close this valve every time the system is started. But if there are no other valves behind the high-pressure pump, the high-pressure water source of the high-pressure pump will directly impact the membrane element every time the system is started, especially when there is air in the system, it will produce 'water hammer' phenomenon, which is easy to cause membrane Fracture of the component. In order to prevent the occurrence of the above phenomenon, an electric slow-opening door should be installed behind the high-pressure pump. After starting the high-pressure pump, slowly open the electric slow-opening door, that is, slowly load pressure on the reverse osmosis membrane of the system. The electric slow-opening door should be fully open. For fully closed valves, the fully open and fully closed time can be adjusted, but it is generally set to 45-60s. Therefore, from the perspective of the safety of reverse osmosis membrane elements, electric slow-opening doors should be installed. That’s it for the introduction of why the industrial edi pure water treatment equipment high-pressure pump should be equipped with a manual adjustment door and an electric slow-opening door. I hope it will be helpful to everyone. I also want to know more about the industrial edi pure water treatment equipment. Welcome to continue to pay attention to our website.
