Improve the daily maintenance plan and quality issues of the circular arc oil pump

[1] Improve the daily maintenance plan of the circular arc gear oil pump

The maintenance technicians of the circular arc gear oil pump should fully grasp the various parameter states of the circular arc gear oil pump during operation. During the inspection and testing process, through parameter analysis, timely eliminate mechanical problems that will not occur at this time. Based on the feeding situation of the circular arc gear oil pump, pump body pressure, vibration situation, and various values obtained from sensors, make the final fault judgment, so as to quickly identify the fault problems of the circular arc gear oil pump operation and propose targeted solutions.

In petrochemical production, technicians often inspect and repair arc gear oil pumps. In response to the problems that occur during the operation of arc gear oil pumps, technicians should fully record the specific problem phenomena and solutions. After long-term inspection and maintenance observation, reasonable daily maintenance plans should be formulated to prevent possible problems that may occur during the operation of arc gear oil pumps. The daily maintenance plans of arc gear oil pumps (including specific inspection plans for key parts and key parts that need close attention, as well as maintenance plans for various mechanical sealing problems) should be analyzed, such as whether there is deformation problem on the mechanical surface. The specific reason for deformation is the loosening of mechanical sealing components. The specific solution strategy is to closely monitor the firmness of mechanical sealing components and reinforce them. Processing

[2] Quality issues with the mechanical seal of the circular arc pump

The principle of the mechanical seal of the circular arc pump is to achieve a tight fit between the sealing pairs through elastic components and medium pressure. When the equipment is running, the dynamic ring that rotates with the shaft and the static ring connected to the sealing shell generate relative rotation, forming a stable liquid film between the sealing surfaces, thereby blocking the leakage of the medium and achieving the end face sealing effect.

(1) There are problems with the manufacturing quality of sealing components

Insufficient hardness of sealing rings, poor sintering quality of graphite rings, and manufacturing quality problems of elastic components.

(2) Insufficient manufacturing accuracy

Mechanical seal manufacturing requires high roughness and flatness of the sealing end face, which is an important quality indicator for sealing.

. If the roughness and flatness of the sealing surface do not meet the standard, it will seriously affect the stability of sealing use; In addition, the manufacturing accuracy of auxiliary seals is also important. For example, if the interference of the auxiliary seal ring of the moving ring is too large, it will jam the moving ring, making it unable to compensate for axial movement and leak. If the interference is too small, it will not be able to play a role in static sealing
