4. The installation of pipelines follows the principle of horizontal and vertical alignment, which is aesthetically pleasing and elegant;
5. The equipment adopts a stainless steel frame structure, which is lightweight;
During the pressure test, there will be no self drop phenomenon due to equipment system problems;
7. Install a safety valve at the high-pressure outlet to prevent equipment overpressure and protect system safety;
8. Drive air inlet: NPT1/2F;
9. Inlet: NPT1/2F;
10. High pressure outlet: 6MF 9/16-18UNF;
11. Unloading outlet: NPT1/2F;
12. Adjusting the driving air pressure reducing valve can regulate the output pressure;
13. The high-pressure unloading valve unloads the pressure in the system;
14. High pressure safety valve pressure limit protection;
15. The high-pressure discharge port must have a device to prevent injury during high-pressure water discharge;
There should be a valve between the outlet of the high-pressure pump and the outlet of the low-pressure pump to prevent damage to the outlet pipeline of the low-pressure pump caused by high pressure;
