Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated:
With reference to accompanying drawing, inducer is equipped with in the present invention below lower drive shaft, and medium is introduced to impeller inlet end, impeller location on pump-foot, better like this axial force while having reduced pump operation, the vibration during to pump operation also improves significantly.Between transmission shaft and transmission shaft, by split type snap ring, be connected, snap ring and two transmission shaft outer ring sleeves have sleeve, and sleeve is spacing by sliding bearing inner sleeve, is convenient to dismounting and change part.Bearing unit adopts two kinds of bearings, while having avoided the interior split bearing assembly of industry to only have a thrust ball bearing, by thrust ball bearing, born rotor part weight and the operation axial force of pump, whole rotor part does not have radial location, in pump operation process, because rotor part exists dynamic unbalance, rotor part can swing, cause pump operation vibration large, sliding bearing abrasion is fast, the mechanical seal fault such as leak; The present invention, above thrust-bearing, sets up a deep groove ball bearing as the radial location of whole rotor part, and the existing axially locating of pump rotor parts has again radial location, and the operation of pump will be more steadily reliable.Bearing adopts thin oil lubricant, on bearing support, the position of oil level indicator is rear definite by calculating, adopt permanent oil level indicator, as long as the lubricating cup of oil level indicator has oil level to show, oil level in bearing support is constant, can guarantee that 1/2 of thrust ball bearing rolling element is immersed in lubricant oil, keep the good lubrication effect of bearing; While uploading moving axis rotation, the deep groove ball bearing on bearing support top is to rely on thrust collar to be distributed with axial rectangular spiral groove and radially to get rid of oilhole along excircle, oil is thrown on the rolling element of upper deep groove ball bearing, realizes splash lubrication.Motor cabinet changes ironcasting into by weldment, and is provided with adjusting bolt, regulates the concentricity of motor and pump, has avoided the welding stress deformation of weldment.
