Abstract

The invention provides coal mining equipment and a cooling system of the coal mining equipment. The coal mining equipment comprises a cooling machine set arranged on a coal mining equipment body, a cooling liquid container and a cooled device set. The cooled device set comprises a plurality of cooled parts which are connected in series and / or in parallel through cooling liquid pipelines, the cooled device set, the cooling machine set and the cooling liquid container are connected in series through the cooling liquid pipelines to form a circulation loop, and split-flow valves are arranged on the pipelines among the cooling machine set and the cooled parts. The cooling system of the coal mining equipment adopts a closed circulation system, external influences on cooling liquid are small, therefore, a cooling effect is good, in addition, all the parts can further adjust flow of the cooling liquid through the split-flow valves to adjust cooling temperature, cooling efficiency is improved, and the failure rate of the equipment is lowered. Furthermore, the cooling liquid does not need to be discharged outwards, water discharging pressure of an operational working face is reduced, less hydration of the working surface is achieved, and therefore operational efficiency can be improved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a coal mine equipment and a cooling system thereof. Background technique [0002] At present, high-power equipment in coal mines is widely used, and it has been recognized and widely used in the industry under the conditions of good ventilation and complete drainage facilities. However, the ventilation conditions of most roadways in coal mines in my country are poor, and the ambient temperature of the working face is greater than 35°C. Therefore, the temperature of existing high-power equipment in coal mines rises rapidly during operation. The working efficiency of coal mining equipment. The cooling system of the existing coal mine high-power equipment mainly has the following deficiencies: [0003] 1. With an open cooling system, the temperature of the coolant is greatly affected by the environment, so the cooling effect is highly correlated with the ambient temperature, the cooling effe...
