Abstract

The invention discloses a chemical process pump with an ultralow vibration value, and belongs to the technical field of chemical process pumps. The chemical process pump comprises a pump body, a pump cover, a bearing body, a pump shaft and an impeller, supporting arms on the two sides of the pump body are designed in an inclined-pull slope shape, and the stability of the center of the pump is improved; the pump cover adopts a forging process, an ultra-large water cooling cavity is used, and a sealing threaded hole is formed in a water cooling cavity cover; and the bearing body adopts a forging process and a cylindrical structure, so that the rigidity and the flexibility of the bearing body are ensured. The chemical process pump has the advantages of high operation reliability, long maintenance period, low accessory replacement rate and long service life, and completely meets the GB / T29531A vibration standard.

Description

technical field [0001] The invention belongs to the technical field of petrochemical process pumps, in particular to an ultra-low vibration value chemical process pump. Background technique [0002] At present, most of the domestic petrochemical process pumps adopt the GB standard. In the refining and chemical enterprises, the maintenance standard of the American refining and chemical enterprises is five years. In our country, the technical indicators of the products cannot reach the technical level of foreign products. In large-scale chemical plants, maintenance is still carried out every three years. In order to achieve the same technical level as foreign equipment, improve the reliability of the equipment, and prolong the service life, parking is not allowed to replace parts within five years, so as to achieve the goal of maintenance every five years. Now, higher requirements are put forward for domestic pump factories. The API610 standard of the American Petroleum Insti...
