Technical Field
The utility model relates to a barring ware technical field especially relates to an automatic barring ware.
Background
At present, a similar barring gear does not exist in the same industry, manual barring by a hexagon wrench is needed, the vertical type multistage centrifugal pump is also called as a CDLF vertical type multistage centrifugal pump, the vertical type multistage centrifugal pump is a non-self-absorption vertical type multistage centrifugal pump which is designed and manufactured by absorbing advanced technologies at home and abroad, a standard vertical motor and multistage mechanical sealing are adopted, the sealing effect is good, the standard vertical type centrifugal pump is suitable for slightly corrosive media, and the standard vertical type centrifugal pump is widely applied to the chemical industry at present. However, because the gaps of the multi-stage sealing surfaces of the pump are small, the gaps of the sealing surfaces are easily blocked by impurities when the pump is in a standby state, and the phenomenon of 'locking of a pump shaft' of the pump can be caused by the superposition of multi-stage sealing resistances. Generally, a maintenance worker must be contacted to disassemble and maintain the pump, and a large amount of manpower and material resources are consumed. If the emergency pump is not processed in time, the emergency pump is not available in case of emergency, and the device can be stopped or even a safety accident can be caused in case of serious emergency. In order to solve the problems, inspection personnel are generally arranged to perform manual barring every hour;
because the pump shaft of the vertical multistage centrifugal pump is sealed in the equipment, the pump shaft cannot be turned for maintenance like a common centrifugal pump. The barring position is located in a groove at the highest position of the pump body, and workers need to climb to the top of the pump body to use an inner hexagon to perform barring when performing barring. The manual barring is low in efficiency, the labor amount of inspection personnel is greatly increased when the field installation quantity is large, and potential safety hazards exist when the inspection personnel operates in seasons easy to freeze in winter.
To this end, we propose an automatic barring gear to solve the above problems.
