Quenching and tempering disposal, processing must be quality and so on, the pump shaft must have corrosive gas and liquid ring material, to use the corresponding corrosion resistance.
International similar product technology, research and development of energy-saving products. It is usually used for suction of non-solid particles, insoluble in water, non-corrosive gas, in order to form a vacuum and pressure in an airtight container. It is a scientific research achievement for many years to produce 2BE1 series water ring vacuum pump and compressor after modifying the flow parts and combining with the experience
It shall be equal to the inlet diameter of the pump. In the installation of the measurement of the pumping rate, there are detailed rules in D(jb1875-73), and the pressure data are recorded in the ministry specifications for the construction size of the test cover and the inner diameter of the test cover. If pressure has change, should use the pressure in measurement process even value. Before the pressure reading on the vacuum gauge is stable for 3min
Ordinary structure of mechanical pump is not suitable for smoke contains a great deal of gases, water yan gas because water vapor will condense in the compression process, and because of pressure increase gradually to the compression chamber are reaching saturation vapor pressure when they are not only used as a diffusion pump or pump before condensation pump, also often used to reduced pressure cooling, drying, distillation process, etc.).
Screw dry vacuum unit brand, international similar product technology, the development of energy-saving products. It is usually used for suction of non-solid particles, insoluble in water, non-corrosive gas, in order to form a vacuum and pressure in an airtight container. 2BE1 series water ring vacuum pump and compressor are produced on the basis of modified flow parts combined with experience.
Jzjs300-2.1 is more suitable. The selection of a larger pre-stage pump should be working at a higher pressure, the longer to and unit to the ability of strong pre-pumping than roots water ring vacuum unit system requirements if but save energy. You can do better
