Scope of application
This type of pump is suitable for oil refineries, petrochemical industry, coal processing engineering, low temperature engineering, paper industry, sugar industry, water supply plant, seawater desalination plant, power plant, environmental protection engineering and shipbuilding industry. Seen from the motor end, the rotation direction of the pump is clockwise.
Material selection
Optional corrosion-resistant materials include 303, 305, 306, 307, 316, 316L, 904, 904L, 804, ECR alloy, NiCr alloy, Hastelloy, CD-4MnCu and titanium alloy, etc., which can meet the requirements of the above media. When ordering, please provide the details of the medium to be transported.
Structural features
1. This type of chemical process is designed according to API standard pipeline. Impeller can be closed, semi-open, open three. Can transport clean, containing particles, containing a small amount of gas medium. Can also transport high temperature, low temperature, strong corrosive medium. The impeller is provided with a balance hole and a corrosion-resistant ring to balance the axial force.
2. The pump body and the bearing frame are connected by the middle connecting section. According to different working conditions, the intermediate connecting section can be made of different materials to avoid serious corrosion of the bearing frame and bearing when conveying strong corrosive medium. At the same time, the middle connecting section is provided with a water-cooled cavity, which passes through the cooling circulating water to block the high temperature medium from transmitting the high temperature to the bearing.
3. The sealing form can adopt packing seal, single and double mechanical seal, and container type single mechanical seal. According to different situations and user requirements for cooling and flushing, sealing can be selected from the case according to API682 design specifications.
4. The bearing frame is designed with three forms: air-cooled heat sink, air-cooled fan and water-cooled cavity, which can be selected by users according to the working conditions.
The bearings are lubricated by oil rings splashed with thin oil from the oil tank. The oil in the oil tank is cooled by the water in the water cooling chamber, and the heat in the bearing is taken away by the cold water to ensure that the bearing is in normal working condition at any time.
5. According to the medium temperature and pressure, the support form adopts the center support and the tripod support.
6. The rated pressure rating of the suction and discharge flanges is the same.
