liquid pump
7.Based on the theories of aerodynamics and fluid dynamics,the efficiency formulas of the pulse generator and the pulsed liquid jet pump device are derived in the pulsed liquid jet pump device with gas__liquid piston The theoretical analysis of pulses liquid jet pump device is compared with the experimental results,the theory agrees with the experiment
10.This paper has technical and economic analyses about urea capacity enlargement from 60 kt/a to 100 kt/a by modifying main units of 60 kt/a total solution recycling urea plant, such as CO 2 compressor, liquid ammonia pump,primary ammonium aminoformic pump, urea converter and medium and low pressure absorption and decomposition systems.
