Abstract

The invention relates to a petrochemical industry process pump. Two pump body insulating jackets are respectively arranged at the outer ring of an inlet section and the outer ring of an outlet section of a pump body, and adopt the all-surrounding structure; an insulating board C is mounted at the lower half part of a flange at the inlet section of the pump body, and the insulating board C is connected with an insulating board A through an insulating board B; a cylinder body insulating board A is a semicircle cylinder body and is arranged along the outer ring of the upper part of the flange at the inlet section of the pump body; a cylinder body insulating board B is a cylindrical cylinder body and arranged along the outer ring of the flange at the outlet section of the pump body, and the cylinder body insulating board B and the cylinder body insulating board A are in penetration; a rightwards-opened n shaped notch is formed in the right end of the cylinder body insulating board B; an insulating top board is arranged above the rightwards-opened n shaped notch; an insulating bottom board is arranged under the rightwards-opened n shaped notch; the insulating top board and the insulating bottom board are connected through a cylinder body insulating board C; two side surfaces of the cylinder body insulating board C are respectively in contact with the cylinder body insulating board B through an insulating sealing board. The petrochemical industry process pump disclosed by the invention is good in insulating effect and can effectively prevent media from solidifying.

Description

technical field [0001] The invention belongs to the field of centrifugal pumps, in particular to a ZE type petrochemical process pump. Background technique [0002] ZE type petrochemical process pump is mainly used in petroleum, chemical industry, water supply plant, power station, food and other industrial sectors to transport clean or particle-containing liquid, low temperature or high temperature liquid, neutral or corrosive liquid. [0003] At present, in the application of horizontal chemical centrifugal pumps, it is found that the traditional pump has no heat preservation structure of the pump body or the heat preservation effect of the existing pump body heat preservation structure is poor. The phenomenon of the pump affects the normal operation of the pump, reduces the service life of the pump and the efficiency of the pump. Contents of the invention [0004] The object of the present invention is to solve the above-mentioned technical problems. [0005] The obje...
