Construction feature
Type DG pump is single casing segmental multi-stage centrifugal pump; the main parts of it are stator, rotor, bearing and shaft seal.
Stator parts: It mainly consists of suction stage, mid-stage, discharge stage and diffuser; they are strained through a lever and form a working chamber. The inlet and the outlet are vertical upward. The combined surface between each stage is sealed through metal surface and also with sealing o-ring as auxiliary seal.
Rotator parts: It mainly consists of shaft, impeller, balancing drum and shaft sleeve. Shaft transfers power to impeller and make it work. The axial force is balanced by balance disc (kettle) and there is exchangeable shaft sleeve in shaft to protect shaft.
Bearing parts: It mainly consists of bearing body, shaft cover and sliding bearing. There are two single centripetal ball bearings in bearing body to prevent balance disc (kettle) from abrasion. The sliding bearing is lubricated by dilute oil, there is cooling chamber in bearing body and the bearing can be cooled with exterior water.
Shaft seal parts: Shaft seal uses soft packing seal. It mainly consists of seal box, packing, packing ring and packing cover. The shaft is sealed, cooled and lubricated by exterior water from seal chamber. The mechanical seal can also be used as requirement and it need be cooled, lubricated and washed by exterior water.
Drive: Pump is directly driven by motor through flexible c |
