The main function of the water ring vacuum pump separator is to separate the liquid from the entrainment in the gas, and according to the different parts of the installation position, the pre gas liquid separator and the rear gas liquid separator are divided.
Pre-gas-liquid separator is mainly used to separate the liquid entrained in the pumped gas, such as the vacuum pump used in the paper industry more.
The post-installed gas-liquid separator is mainly used to separate a large amount of liquid entrained in the discharge gas when the water ring vacuum pump and compressor work.
The design pressure and working pressure of separators can be roughly divided into three types:
The first is a separator that works in a vacuum. The design pressure is from -0.1Mpa to -0.02Mpa. The standard for design and calculation is GB150 – 1998 steel pressure vessel. The products of the company mainly include pre – splitter.
The second kind is the separator working in the normal pressure state. The design pressure is from more than -0.02Mpa to less than 0.1Mpa. The standard of design and calculation is JB/T4735–1997 “steel welding permanent pressure vessel”. The products of the company are mainly used in the separator of various vacuum pumps.
The third kind is a separator working under positive pressure. The design pressure is from 0.1Mpa to no more than 35Mpa. The rules and standards based on the design and calculation are “Pressure Vessel Safety Technical Supervision Regulations” and GB150 – 1998 “steel pressure vessel”.vacuum-pump-application-in-the-freeze-drying-industry
Water ring vacuum pump nouns interpretation:
Working pressure: pressure vessel withstanding internal pressure, the highest working pressure refers to the normal use of the process, the top may appear the highest pressure;
The maximum pressure is the maximum pressure difference that may occur during the normal use of the pressure vessel, and the maximum pressure difference may appear on the top of the jacket container.
Design pressure: design pressure refers to the highest pressure at the top of the set of the set, with the corresponding design temperature as the design load condition, the pressure vessel design pressure should not be lower than the maximum working pressure, the pressure vessel equipped with safety relief device, its design pressure should not be lower than the opening pressure of the safety valve or the explosion of the blasting piece.
