Supercharging device for nanofiltration machine

The pressurizing device comprises a pressurizing pump main body, one end of the pressurizing pump main body is fixedly connected with a water inlet pipe, one end of the water inlet pipe is fixedly connected with a first flange plate, the interior of the water inlet pipe is in threaded connection with a fixing ring, and the interior of the fixing ring is fixedly connected with a filter screen. One end of the booster pump main body is fixedly connected with a water inlet pipe, the other end of the booster pump main body is fixedly connected with a water outlet pipe, a flow valve is arranged in the water outlet pipe, and one end of the water outlet pipe is fixedly connected with a second flange plate. The water flow flows out of the water outlet pipe and enters the nanofiltration machine, the flow valve can automatically eliminate the hydraulic disorder phenomenon caused by various factors in a water system, the flow needed by a user is kept, and the device can avoid the problem that the water flow is unbalanced
