High-pressure ammonium pump operating conditions Characteristics: The pump is used to medium pressure recovery of the bottom of the recovered methyl ammonium solution from about 1-7MPa (G) boost to about l5.4MPa (G), after the pre-heater Send to high-pressure ammonium condenser. The pump (magnetic pump) operating conditions are as follows: ①transmission medium carbamate aqueous solution, different components of different processes. For the ammonia stripping method, the components of the ammoniacal liquid are as follows: NHa 48.5%, C0219%, H2032.5%, temperature 75-80 ℃, solution density 0.9-1 × 10-8k / Information free to send!

Pump inlet pressure is higher, stripping process for the 0.5 ~ 2.5MPa (G), so that the pump shaft seal pressure slightly higher than the conditions used. Pump working pressure up to 15 ~ 25MPa (G). ③ Methylammonium solution is highly corrosive to metal materials, coupled with high pressure pump body, the pump material must have excellent anti-fatigue corrosion resistance and mechanical strength. ④ high reliability requirements. The pump is one of the key equipment in the production of urea, but also the easiest part of the entire device failure, the reliability of the level of a direct impact on the urea production of continuous operation cycle.
