How to effectively reduce the wear of the intelligent self suction pump crankshaft

Intelligent self suction pump is a device that draws air through a vacuum zone formed by an internal water ring. Due to the high working intensity of self priming pumps, equipment wear may occur after long-term operation, among which crankshaft wear is a common type. Introduce how to effectively reduce wear.

The surface wear of the crankshaft journal of the self suction pump is uneven, and the radial wear of the main journal and connecting rod journal is mainly elliptical. The wear parts of the pump correspond to each other, that is, the wear parts of each main journal are close to the side of the connecting rod journal; The wear of the connecting rod journal is also close to the side of the main journal. The crankshaft journal also has conical wear along the axial direction, and the elliptical wear of the journal is caused by the uneven distribution of forces acting on the journal in the circumferential direction.

When the self priming pump engine is working, the comprehensive force on the connecting rod journal always acts on the inner side of the connecting rod journal, and the direction is outward along the radius of the crankshaft, causing wear on the inner side of the connecting rod journal and forming an oval shape. The reason for the wear of the connecting rod journal of the intelligent self suction pump is that the oil passage leading to the connecting rod journal is tilted. Under the action of centrifugal force, mechanical impurities in the lubricating oil accumulate on one side of the connecting rod journal, causing the wear of the connecting rod journal to be conical.

When using a self priming pump, the surface of the shaft neck may be scratched and burned. Wear is mainly caused by unclean engine oil, which has large hard mechanical impurities scraping on the surface of the journal. The burning of tiles on the shaft surface is caused by burning tiles, mainly due to insufficient oil and other factors.

The wear of the crankshaft of the self suction pump is mainly caused by uneven force and improper cleaning and maintenance, because the wear of the crankshaft directly affects the service life of the intelligent self suction pump equipment. Therefore, when using the intelligent self suction pump in practice, we must operate it in a standardized manner, regularly maintain and lubricate the self suction pump, so as to ensure that the self suction pump will not have potential problems.
