Pump Manufacturing Co., Ltd. Dalian Baolong by the production and petrochemical process pump shield pump compared to a clear advantage.

1. Explosive conditions: petrochemical pumps with mechanical seals, sealing rings moving mirror principle of mechanical seal formed when the liquid in the high-speed rotation of mechanical seal for cooling. Leak hazards. Explosion-proof shield pump machine, completely leak. Explosion levels DIIBT3/DIIBT4, protection grade: IP54/IP55, more suitable for explosive conditions;

2. Petrochemical process pump according to API610 standards, according to the standard mechanical seal in PLAN11/PLAN11 +52 API682 program comparison: the inlet pressure is too large, resulting in short life PLAN11 mechanical seal. PLAN11 +52 program led to excessive procurement costs. The selection of shielding design pressure pump according to user requirements, regardless of inlet pressure.

3. The use of cost comparison: In addition to the impeller, the pump and other components, the petrochemical pump spare parts, which normally takes 2 years to submit a bearing / mechanical seal / shaft nut / shaft / bearing retainer / Plum pad / coupling / machine closure pressure cover, etc., but generally only submitted shield pump bearing / shaft + thrust bearing can be.
