Abstract

The invention provides a pump shell, and relates to the field of mechanical design and manufacturing thereof. A pump shell comprises a bearing seat and a suspension body, the bearing seat is of a barrel structure, a first cavity, a second cavity and a third cavity are sequentially formed in the bearing seat in the same direction, the diameter of the second cavity is larger than that of the first cavity and that of the third cavity, and an oil injection hole is formed in the bearing seat and communicated with the second cavity. And a heat dissipation layer is arranged on the side wall of the second cavity. According to the pump shell, a better heat dissipation effect can be provided, and the service life of the pump shell is prolonged.

Description

technical field [0001] The invention relates to the field of mechanical design and its manufacture, in particular to a pump casing. Background technique [0002] High temperature heat medium pump, also known as hot oil pump, is a fluid machine used to transport high temperature heat medium. Widely used in petroleum, chemical, rubber, plastic, pharmaceutical, textile, printing and dyeing, road construction, food and other industrial fields, the amount is huge, and the annual sales amount to billions of yuan. The polyester chemical fiber industry alone purchases and uses hundreds of millions of high-temperature heat medium pumps every year. The hot oil pump is an ideal hot oil circulation pump or a heat transfer pump, and it is an ideal matching pump for heat exchange equipment. [0003] However, most of the current hot oil pumps have the problem of poor heat dissipation, which causes the hot oil pump to be used at high temperature for a long time, which affects its service ...
