پمپ خلاء حلقه مایع
نام انگلیسی:
Liquid ring vacuum pump PW, DW series
برند:
Hydro-Vacuum
مشخصات:
Rotating liquid ring vacuum pumps and blowers (commonly known as compressors) are used in various processes which demand suction and forced flows of oil-free gases, especially in the chemical, pharmaceutical, food processing, paper-making, and textile industries, as well as for the priming of impeller pumps and siphons.
PW, DW pumps are used in:
chemical,
pharmaceutical,
food processing,
paper,
textile industry.
It is possible to pump dry gases at temperatures of up to 150oC, and vapour-saturated gases at temperatures of up to 100oC with a 30% maximum liquid content of the working fluid demand, for operation in direct supply systems, termed “PB”. When pumping saturated gases, the amount of working liquid at the input to a compressor via a line shall be reduced by the amount of liquid arriving with the gas to prevent the drive from overloading. If the mixture temperature at the pump intake exceeds the rated temperature in the PB system (which is 15oC for water), the efficiency of the gas pumped by an IP should be corrected as required. The permissible temperature of the working liquid at the compressor output should not exceed 80oC.
Various types of working liquids can be used, as required by processing, but the liquid must meet the following requirements:
density: 800 to 1200kg/m3,
viscosity: 60 mm2/s maximum at 20oC,
corrosivity of the working liquid: should not exceed the resilience of the compressor hydraulic stage materials.
