Accompanying drawing explanation
Fig. 1 is the structural drawing of an embodiment of the present utility model.
Embodiment
To illustrate below in conjunction with accompanying drawing and embodiment further illustrates the utility model.
As shown in Figure 1, the structural drawing of the radial subdivision centrifugal pump of two-stage single suction, comprises drive end pump cover 15, inter-stage pump cover 13, anti-drive end pump cover 12, the pump housing 1 and rotor part fill 17, described drive end pump cover 15, anti-drive end pump cover 12 covers at the described pump housing 1 two ends, and described inter-stage pump cover 13 is arranged in the described pump housing 1, the described pump housing 1, drive end pump cover 15, inter-stage pump cover 13, run through described rotor part in anti-drive end pump cover 12 and fill 17, the two ends that described rotor part fills 17 pass described drive end pump cover 15, anti-drive end pump cover 12, described rotor part fills on 17 and is provided with two impellers 14, described impeller 14 is arranged in the described pump housing 1 back-to-back, the described pump housing 1 is provided with a suction port and a discharge opening, the two ends that described rotor part fills 17 be separately installed with front axle bearing portion fill 18 and rear axle bearing portion fill 10, described front axle bearing portion fills between 17 and described drive end pump cover 15, described rear axle bearing portion fills between 10 and described anti-drive end pump cover 12 and is equipped with bearing bracket 9, described impeller 14 and described drive end pump cover 15, inter-stage pump cover 13, anti-drive end pump cover 12, casing ring 7 is equipped with, impeller ring 3 between spacer sleeve 16, throat's lining 2, throat's lining 4, throat's quilt cover 8.
In the utility model, the described pump housing is connected with oil draining system 61 time, and described bearing bracket is connected with drainage 59 times, and the described pump housing 1 and machine seal rinse-system 11 and be connected, and described oil draining system 6, drainage 5 are all connected with same outer pipe.Centered by the radial subdivision centrifugal pump of described two-stage single suction, line supports.
Structure of the present utility model is from compact type pumps such as traditional integral pump pin, water-cooling type bearing support, the huge type of single spiral case equal-volume split type technique pump pin till now, alternative type of cooling (water-cooled, air-cooled, naturally cool), double socket shells, not only make the profile of pump more attractive in appearance, and further increase the reliability of pump.This pump is radial subdivision two end supports formula heavy duty centrifugal pump, can be used on petroleum refining, petrochemical industry and chemical industry and carry the oil, liquefied petroleum gas (LPG) and other medium that do not contain solid particle, be particularly suitable for conveying High Temperature High Pressure and inflammable and explosive or poisonous liquid, its mounting type is that horizontal center line supports.
