Structure Description multistage pump consists of a stator, rotor, bearings and shaft seal: 1, multi-stage pump stator portion mainly by inhalation, middle, spit segments and vanes and other components DG6-25X9 multistage centrifugal pump, there is tension bolt clamping the segments constituting the studio. D-type pumps are generally horizontal suction, vertical spit up; when used in oilfield water injection pump inlet are vertical. DG-type multi-stage pump out the entrance are vertical. 2, multi-stage pump rotor portion consists of shaft, impeller, balance disc and sleeve and other components. The axial force on the balance disc balance. 3, multi-stage pump bearings consist of bearing body, bearing and bearing gland and other components, bearings with grease or oil lubrication. 4, multistage pump shaft seal soft packing seal DG12-25X3 multistage centrifugal pumps, mainly by water segment and end cap sealed casing, packing, retaining rings and other components. D-type pump seal water from the pressure of the water pump. DG pump seal water from an external water supply. 5, multi-stage pump rotational pump through flexible coupling directly driven by the prime mover. From the motor end pump, the pump is clockwise rotation D, DG-type pump is a horizontal single-suction multistage segmental centrifugal pump. For the transport of water (less than 1% impurity mass, particle size less than 0.1mm) or physical and chemical properties similar to water, other liquids. D-type pump transmission medium temperature less than 100 ℃, applicable to mine drainage, oil field water, factories and urban drainage and other occasions. Oilfield injection pump according to corrosive media, the pump using different materials. DG pump transmission medium temperature less than 120 ℃ DG12-25X4 multistage centrifugal pumps for a variety of boiler feedwater. Anguo Shi Yuan Pump Co., Ltd. is the design, development, manufacturing, sales and service in one, Main: slurry pump, filter feed pump, filter pumps, filter pump, filter press feed feed pump, D-type multi-stage pump, DG-type multi-stage pump, LG-type multi-stage pump, pipeline pumps, chemical pumps, slurry country established 26 branch structure, the consolidation of a sound sales service network. Three, D single suction multistage centrifugal pump to start moving forward and stop handling: (a) connection with the order: (1) the seal ring are firmly mounted in the water segment and guide vanes bezel. (2) the lead in the middle of the wing suit, and then the guide wings installed in all of the middle of the bezel up. (3) will be installed and suspect yu A shaft sleeve through the water segment, and push the impeller into the water segment sequentially in the middle and end cap packing room. (8) the bearing body were installed to cover more water segment and tail and bolted. (9) into the bearing retainer sleeve, ball bearings, and nuts to secure. Boiler feed pump (Figure), DG6-25X8 multistage centrifugal pumps, multistage centrifugal pump provided by the Anguo City Pump Co., Ltd. Shi Yuan. Anguo Shi Yuan Pump Co., Ltd. (www.shiyuanbeng.com) located in Hebei Province Road King Industrial Zone Anguo pump. Scraps and development in the wave of market economy, the current Shiyuan water pump has a high profile in centrifugal pumps, and enjoys a good reputation. Shiyuan water pump made whole network business alliance certification, marking our service and management level has reached a new height. Shiyuan Pump staff is willing to common development with all people a better future.
