Chemical process pump is the general name of various pumps in the chemical production process. The pump is equipped with large power, high speed, small overall volume, simple structure and easy maintenance, but high temperature, easy wear and large maintenance coefficient. Therefore, it is relatively difficult to maintain and maintain the pump. In order to reduce the number of overhauls, the maintenance and maintenance of the equipment must be done well.
advantage
1. Impeller can be closed, semi-open or open. Can transport clean, containing particles, containing a small amount of gaseous media. It can also transport high temperature, low temperature, and strong corrosive media. 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 an intermediate connection section. According to different working conditions, the intermediate connection section can be made of different materials to avoid severe corrosion of the bearing frame and bearings when conveying strong corrosive media. At the same time, the middle connection section is provided with a water-cooled cavity, which is passed through the cooling circulating water to block the high-temperature medium from transmitting high temperature to the bearing.
3. The sealing form can adopt packing seal, single and double end mechanical seal, and cartridge type single end mechanical seal. According to different situations and user requirements for cooling and flushing, the seal can be selected from the case according to the API682 design specification.
4. The bearing frame is designed with air-cooled fins, air-cooled fans, and water-cooled cavities. Users can choose according to the operating conditions. The bearings are lubricated by oil rings splashing thin oil from the oil tank. The oil in the oil tank is cooled by the water in the water-cooled cavity, 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 temperature and pressure of the medium, the support form uses center support and foot support.
