Description

Technical Field

[0001] This utility model relates to the field of centrifugal pump technology, and in particular to a temperature and vibration measuring structure bearing bracket for centrifugal pumps. Background Technology

[0002] Centrifugal pumps operate by using the centrifugal motion of an impeller to move water. Before starting the pump, the pump casing and suction pipe must be filled with water. Then, the motor is started, causing the pump shaft to drive the impeller and water to rotate at high speed. The water undergoes centrifugal motion, being thrown towards the outer edge of the impeller and flowing into the pump's discharge pipe through the flow channel of the volute casing. As crucial equipment in industries such as chemical, petroleum, and pharmaceutical, the performance and stability of centrifugal pumps are essential for the operation of the entire production line.

[0003] In the past, real-time monitoring equipment for the operating status of centrifugal pump bearings was not widely used during operation. Repairs were often only carried out after bearing failures caused problems with the pump's safe operation. Bearing temperature and vibration have a significant impact on the lifespan of both the bearing and the pump. Without real-time monitoring of bearing temperature and vibration values, it is impossible to predict bearing fatigue strength in advance, leading to uncontrollable production accident risks and increased maintenance costs. Utility Model Content

[0004] The purpose of this invention is to address the problem that in the past, real-time monitoring equipment for the operating status of centrifugal pump bearings was not widely used. Repairs were often only carried out after bearing failures caused problems with the safe operation of the pump. Bearing temperature and vibration have a significant impact on the lifespan of both the bearing and the pump. Without real-time monitoring of bearing temperature and vibration values, it is impossible to predict bearing fatigue strength in advance, leading to uncontrollable risks of production accidents and increased maintenance costs. Therefore, this invention proposes a temperature and vibration measuring bearing bracket for centrifugal pumps.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a bearing bracket for a centrifugal pump with temperature and vibration measurement structure, comprising a frame body, wherein the frame body has a drive end assembly cavity and a non-drive end assembly cavity, both of which are used to install bearings; an outer mounting block is fixedly connected to the outer surface of the frame body, located outside the drive end assembly cavity; a non-drive end temperature measurement interface and a non-drive end vibration measurement interface are provided on the outer surface of the frame body, located outside the non-drive end assembly cavity; the number of outer mounting blocks is four, wherein the interior of two of the outer mounting blocks has a through-hole drive end temperature measurement interface, and the interior of the other two outer mounting blocks has a through-hole drive end vibration measurement interface. Both the drive-end vibration measurement interface and the drive-end temperature measurement interface are connected to the drive-end assembly cavity. Both the non-drive-end temperature measurement interface and the non-drive-end vibration measurement interface are connected to the non-drive-end assembly cavity. The central axes of the drive-end vibration measurement interface and the drive-end temperature measurement interface are perpendicular to each other, and the central axes of the non-drive-end temperature measurement interface and the non-drive-end vibration measurement interface are perpendicular to each other. The interiors of both the drive-end temperature measurement interface and the non-drive-end temperature measurement interface are used to install temperature measuring elements, and the interiors of both the drive-end vibration measurement interface and the non-drive-end vibration measurement interface are used to install vibration measuring elements. Both temperature measuring elements adopt the form of adjustable movable threaded ferrules, which can reduce the assembly risk caused by machining errors. Both temperature measuring elements and vibration measuring elements contact the outer ring of the bearing.
