Single screw pump pressure to determine the maximum output pressure of single screw pump is based on series lead bushing bushing is determined by the:
Level 1: the maximum working pressure is 0.6MPa;
Level 2: the maximum working pressure is 1.2MPa;
Level 4: the maximum working pressure is 2.4MPa;
According to media wear of pump selection speed wear medium. The rotational speed (RPM) no fresh water, coagulant, oil, juice, minced meat and heat pumps, soap and water, blood, glycerin 400-1000 general mud, suspension, industrial wastewater, paint pigments, waste water (sugar), mortar, fish, wheat bran, rapeseed oil filter sediment 200-400 serious lime, clay, plaster, clay 50-200 mechanical seal is given in the delivery of specific media and wear characteristics of a special case of, please pay attention to the changes in the characteristics of the medium concentration and temperature changes. The single screw pump when the pump size is large, the speed should be lower. Diving sewage pump table three vacuum pump fluid viscosity select pump speed medium viscosity (CST) 1-10001000-1000010000-100000100000-1000000 speed (RPM) 400-400 rotary vane vacuum pump 200-400<200<100 in the selection of speed to according to the experience, because a number of other factors also affect the choice of speed.
