Working conditions: liquefied petroleum gas LPG / propylene (C3H6) n transportation parameters: the general design of the import pressure of 13 to 16 kilograms, to be 150 or more pump head pump options: API standard petrochemical process pump VS shielding pump reference manufacturers: Dalian Baolong Pump Manufacturing Co., Ltd. Petrochemical industry liquid hydrocarbons / light oil / LPG / propylene and other conditions. Compared with the petrochemical process pump, the shield pump produced by Dalian Baolong Pump Manufacturing Co., Ltd. has obvious advantages. 1. Flammable and explosive conditions: the use of mechanical seal of the petrochemical pump, seal the principle of the closure of the mirror ring to form a liquid film at high speed rotation, the machine seal cooling. There are hidden dangers of leakage. Shielding pump machine explosion-proof, completely leak-free. Explosion-proof grade DIIBT3 / DIIBT4, protection class: IP54 / IP55, more suitable for flammable and explosive conditions; 2. Petrochemical process pump according to API610 standard, according to machine seal standard API682 PLAN11 / PLAN11 +52 program comparison: import pressure is too large, resulting in PLAN11 machine seal service life is short. PLAN11 +52 program led to procurement costs are too large. The selection of shielding pump can be designed according to user requirements pressure, do not have to consider the import pressure. 3. Use cost comparison: In addition to the impeller, the pump body and other components, two years of spare parts of petrochemical pump spare parts generally need to be reported bearing / mechanical seal / shaft nut / shaft / bearing retainer / plum pad / coupling / machine gland , While the shield pump generally only need to mention bearing / sleeve + thrust plate can be. Summarize the main points above, the choice of shielding pump in the industry has the advantage. Source: Dalian Baolong Pump Manufacturing Co., Ltd.
