Centrifugal pump lubricating oil supply system and circulating method thereof

Abstract

The invention relates to the technical field of centrifugal pump lubrication, in particular to a centrifugal pump lubricating oil supply system and a circulating method thereof. The centrifugal pump lubricating oil supply system comprises a lubricating assembly, wherein a circulating device is fixedly connected to the bottom of the lubricating assembly, a filter pipe fitting is inserted into the bottom of the circulating device, a water temperature adjusting device is fixedly connected to the right side of the circulating device, and the top of the circulating device communicates with a pressure reverse stopping device. The lubricating assembly is improved, lubricating oil is concentrated above a rotating shaft, the rotating shaft is continuously lubricated in an infiltrating mode, the lubricating oil is gathered in an oil channel, the smearing area of the lubricating oil is increased, the heat dissipation effect is improved, oil on the rotating shaft is scraped away through a scraping strip, and therefore, long-time detention of oil on the rotating shaft is avoided, the cleanliness of lubricating oil is guaranteed, the use period and the replacement period are prolonged, carbon deposition and impurities are avoided in the process, and the safety of the rotating shaft is protected.

Description

technical field [0001] The invention relates to the technical field of centrifugal pump lubrication, in particular to a centrifugal pump lubricating oil supply system and a circulation method thereof. Background technique [0002] Centrifugal pump refers to the pump that transports liquid by the centrifugal force generated when the impeller rotates. It is mainly composed of impeller, pump body, pump shaft, bearing, sealing ring and stuffing box. Its main features include: compact structure, wide range of flow head, uniform flow, stable operation, small vibration, low maintenance and repair costs, etc. [0003] During the operation of the centrifugal pump, since the rotating shaft needs to be coated with lubricating oil, the internal lubricating oil will change color under the action of dust and high temperature after long-term use, and solid particles will appear on the rotating shaft if it is not cleaned for a long time. When rotating, scratches appear on the surface of th...

AI Technical Summary

Problems solved by technology

[0003] During the operation of the centrifugal pump, since the rotating shaft needs to be coated with lubricating oil, the internal lubricating oil will change color under the action of dust and high temperature after long-term use, and solid particles will appear on the rotating shaft if it is not cleaned for a long time. When rotating, scratches appear on the surface of the rotating shaft, which will affect the life of the rotating shaft, and when the centrifugal pump is used in winter, the internal lubricating oil will emulsify or even agglomerate, which will affect its normal use, and the lubricating oil in the centrifugal pump that has been running for a long time The oil temperature rises abnormally, causing the internal parts to be heated, affecting long-term use
