AI Technical Summary

Technical Problem

Existing centrifuges lack monitoring devices to monitor the flow changes of lubricant in real time, which makes it difficult to detect leakage and blockage problems in a timely manner, affecting equipment performance, and traditional flow meters are large in size and occupy space.

Method used

A lubricating structure including a differential pressure sensor is designed. By providing a differential pressure sensor between the first oil circuit and the second oil circuit, the change in the pressure difference between the two is detected to monitor the flow of the lubricating fluid, and a sealing mechanism is used to prevent it. Liquid leakage and blockage, the pressure differential sensor is not affected by the electrical characteristics of the lubricating fluid, and does not occupy additional space in small size.

Benefits of technology

Real-time monitoring of lubricant flow is achieved, leakage and blockage can be detected in time, and the performance and efficiency of the centrifuge are improved, and the equipment is compact and requires no additional space.

Abstract

The utility model discloses a lubricating structure of a centrifugal machine, which belongs to the technical field of centrifugal machine equipment and comprises a driving motor, an output shaft, a plurality of bearings, a shaft sleeve, a connecting sleeve, a lubricating oil tank, a first oil way and a second oil way. A differential pressure sensor is arranged in the connecting sleeve, and the two detection ends of the differential pressure sensor are located in the first oil way and the second oil way correspondingly. And a differential pressure sensor is arranged between the first oil way and the second oil way to detect the differential pressure of the lubricating liquid in the two oil ways and monitor the flow between the oil ways. The differential pressure sensor performs numerical conversion on electric signals generated by the bridge through the pressure difference between internal media at the two ends, so that the differential pressure sensor is not influenced by the electrical characteristics of lubricating liquid, is small in size and does not occupy extra space of a centrifugal machine.
